Description

A parallel PE filter device that is easy to clean Technical Field

[0001] This utility model relates to the field of filtration devices, and in particular to a parallel PE filtration device that is easy to clean. Background Technology

[0002] In the production of soda ash, the filtration and purification of raw material liquid is a key link affecting product quality and production efficiency. Early processes mostly adopted the clarification tank primary clarification technology, but it had problems such as large equipment size, insufficient effective clarification area, and poor resistance to production fluctuations, making it difficult to meet the production needs of high-purity soda ash. In the past, PE microporous filters were mostly used for filtration.

[0003] However, existing equipment is prone to causing impurities to flow back into the raw material liquid during maintenance and cleaning, thus contaminating the raw material liquid. It is also difficult to isolate the raw material liquid during cleaning and maintenance, which reduces production efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a parallel PE filter device that is easy to clean and facilitates the isolation of raw material liquid for maintenance and cleaning, thereby improving production efficiency.

[0005] The technical solution is: a parallel PE filter device that is easy to clean, comprising four support legs, a tank fixedly connected between the four support legs, a diversion pipe fixedly connected to the lower part of the tank, two connecting bends fixedly connected to one side of the diversion pipe, a filter fixedly connected to the end of each connecting bend away from the diversion pipe, one of the filters, one of the connecting bends, the diversion pipe and the interior of the tank being in communication, a tee pipe fixedly connected to the outlet of each filter, a wastewater pipe fixedly connected to each tee pipe, and a tee ball valve installed inside each tee pipe. A water pump is fixedly connected to one side of the tank. An inlet pipe is fixedly connected to the inlet of the water pump. The end of the inlet pipe away from the water pump is located inside the tank. A limit frame is fixedly connected between two connecting bends. A movable interface is slidably connected to the limit frame. A flow plate is slidably connected inside the diversion pipe. The flow plate has two through holes. An electric push rod is fixedly connected to the diversion pipe. The telescopic rod of the electric push rod is connected to the flow plate. A connecting rod is connected between the telescopic rod of the electric push rod and the movable interface. A connecting hose is connected between the upper part of the movable interface and the outlet of the water pump.

[0006] The beneficial effects are: by rinsing before introducing the raw material liquid and isolating the filter part that needs to be cleaned, the filter will not allow impurities to flow back into the raw material liquid due to being connected to the tank during cleaning, and the filtration work can be carried out continuously during cleaning or maintenance of the filter without affecting production efficiency.

Detailed Implementation

[0011] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] Example 1

[0013] A parallel PE filter device for easy cleaning, as shown in Figures 1-3, includes four support legs 1, with a tank 2 fixedly connected between the four support legs 1. A diversion pipe 3 is fixedly connected to the lower part of the tank 2. Two connecting bends 4 are fixedly connected to one side of the diversion pipe 3. A filter 5 is fixedly connected to the end of each connecting bend 4 away from the diversion pipe 3. One filter 5, one connecting bend 4, the diversion pipe 3, and the tank 2 are in communication. A tee pipe 6 is fixedly connected to the outlet of each filter 5. A wastewater pipe 7 is fixedly connected to each tee pipe 6. A tee ball valve 8 is installed inside each tee pipe 6. The tank 2 is fixedly connected to one side of the diversion pipe 2. A water pump 9 is provided, and an inlet pipe 10 is fixedly connected to the inlet of the water pump 9. The end of the inlet pipe 10 away from the water pump 9 is located inside the tank body 2. A limit frame 11 is fixedly connected between the two connecting bends 4. A movable interface 12 is slidably connected to the limit frame 11. A flow plate 13 is slidably connected inside the diversion pipe 3. The flow plate 13 has two through holes. An electric push rod 14 is fixedly connected to the diversion pipe 3. The telescopic rod of the electric push rod 14 is connected to the flow plate 13. A connecting rod 15 is connected between the telescopic rod of the electric push rod 14 and the movable interface 12. A connecting hose 16 is connected between the upper part of the movable interface 12 and the outlet of the water pump 9.

[0014] In actual operation, the operator first introduces the raw material liquid into the upper part of the tank 2. Due to sedimentation, a clear liquid layer forms on the upper part of the tank 2. Initially, the electric push rod 14 is in the extended state, and the three-way ball valve 8 disconnects the three-way pipe 6 from the connecting hose 16, thus connecting the other two ports of the three-way pipe 6. The hole on the flow plate 13 connects the diversion pipe 3 to one of the connecting bends 4, and the moving interface 12 connects to the other connecting bend 4. Therefore, the liquid entering the tank 2 only flows through one of the connecting bends 4 and one of the filters 5, while the other filter 5 and connecting bend 4 are idle. After being filtered by the filter 5, the raw material liquid finally flows out through the three-way pipe 6. When it is necessary to clean the filter 5, the operator first opens the three-way ball valve 8 located at the idle filter 5, connecting the three-way pipe 6 to the connecting hose 16, thus disconnecting the other two ports of the three-way pipe 6. Then, the operator starts the water pump. 9. Pump 9 draws out the clear liquid layer in tank 2 and passes it through connecting hose 16 and moving interface 12 into one of the unused connecting bends 4. The pumped clear liquid then flushes the unused filter 5, cleaning any impurities or waste residue that may be present inside the filter 5. Finally, the liquid is discharged through wastewater pipe 7. After flushing, the operator resets the three-way ball valve 8, shuts off pump 9, and then starts electric push rod 14. The retraction of electric push rod 14 causes flow plate 13 to move horizontally a certain distance, aligning the through hole on flow plate 13 with one of the previously unused connecting bends 4. One of the connecting bends 4 that was previously connected to the diversion pipe 3 is blocked. Flow plate 13 ensures that only one connecting bend 4 remains connected to diversion pipe 3 at a time. This prevents impurities from flowing back into the raw material liquid when the filter 5 is being cleaned due to its connection with tank 2, and allows continuous filtration during cleaning or maintenance of filter 5 without affecting production efficiency.
