Debugging steps for fully automatic dosing device

 As the name suggests, the dosing device is a mechanical automated dosing system, which is widely used in water treatment, petroleum, chemical and other industries. The operation process of the dosing device is very simple. It can be operated manually or through a controller, but when adding Corresponding debugging work must be done before the medicine device starts working. This is necessary to avoid unnecessary trouble!

 

  1. 1.Check whether the water source and power supply are connected.

 

  1. 2.Set the control button of the electric control box to the "manual" position, and check one by one whether each device is intact and whether the motor rotation is correct (the valve on the water inlet pipe should be opened when checking the rotation of the feed motor).

 

  1. 3.Use your hands to move the float ball up and down one by one to see if it can send out a signal normally, and then check whether the level alarm in the hopper can work normally.

 

  1. 4.Put dry PAM solid powder (not less than 5Kg) into the hopper and place a suitable container at the feed port.

 

  1. 5.Open the water inlet valve and press the feed motor start button. Feeding will start at this time. After running for one minute, feeding will stop.

 

  1. 6.Weigh the polymer mass in the container and make records.

 

  1. 7.Repeat steps 5 and 6 above, and predict the average weight of the powder fed through the feeder.

 

  1. 8.Repeat the above three steps and make good records. Since the feed rate is controlled and the feeder speed is known, the feed rate curve can be drawn for future reference. You can also directly adjust the amount of powder and water to a certain value to prepare the solution (for example, to prepare a 5‰ PAM solution of 1000L/h, you can directly adjust the amount of powder to 5Kg/h and the amount of water to 1000L/h).

 

  1. 9.Stop the feeder.

 

  1. 10.Turn the control switch in the electric control box to the "automatic" position.

 

  1. 11.When the liquid level reaches a high level, the feeder should be able to automatically stop, stop water inflow at the same time, and start the metering pump (or open the drain ball valve of the liquid storage room). When the liquid level reaches a low level, the feeder should be able to automatically open the feeder. Material, water.

Comparison of filter press selection, which one has more advantages in treating sludge?

图片
  Now, no matter which industry it is, and no matter what kind of  sludge treatment equipment  is needed, filter press is indispensable after all, because whether it is to compress the sludge first or to transport the sludge, it still needs to be processed. The effect of dewatering sludge will be better than that of dewatering sludge, because only  filter press equipment  can effectively utilize the sludge and meet environmental protection standards after filtration. For example, some sludge is filtered and the filtrate becomes clear water, which can be directly It is recycled again. As for the filtered mud cake, some are landfilled and incinerated, and some are recycled and reused, depending on the needs of various industries, and only filter press equipment can achieve these. Therefore, users are dazzled when it comes to filter press selection, because not every filter press can achieve low filter cake moisture content and high filtration speed. Today we will ...

Which industries use high-pressure membrane filter presses?

图片
Ordinary  chamber filter presses  are suitable for most industries. The normal moisture content of the mud cake is about 75%, while the normal moisture content of the mud cake of high-pressure membrane filter press is about 65%, depending on the materials and processes. The  diaphragm filter press  is a filter press with a diaphragm plate and a chamber filter plate arranged alternately to form a filter chamber. It is a filter press with an elastic membrane installed between the filter plate and the filter cloth. The solids and liquids in the slurry are separated through the filter media (filter cloth). When the solids in the slurry form a cake, air or water is passed into the membrane filter plate to fully squeeze the solids in the filter chamber and reduce the moisture content. Generally, this filter press can be used for materials with higher viscosity and users with higher moisture content requirements. During use, when the feeding is completed, high-pressure flui...
