Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid separation technology, specifically relating to a dilute phase suspension concentration device. Background Technology

[0002] Currently, filtration of liquid materials is necessary in research and production processes in the food, cosmetics, chemical, biological, and pharmaceutical industries to purify the liquids. However, most existing pressure filtration devices have complex pressurization structures; filter cloth replacement is cumbersome, requiring disassembly of the filter cloth each time sludge is discharged, which is time-consuming and labor-intensive; sludge discharge efficiency is low, and filter residue accumulates on the surface of the filter cloth, requiring manual cleaning after machine shutdown, which increases the operating cost of the device and affects its ease of use.

[0003] Chinese patent CN 222218833 U discloses a quick-release pressure filter for epoxy resin, which solves the problems of difficulty in replacing or cleaning the filter screen and the easy breakage of the filter screen during pressure filtration after epoxy resin production. However, when cleaning the filter screen, it is necessary to manually remove it using a steel rod welded to the spiral cover plate, and then clean the filter screen, which affects the overall efficiency of the device.

[0004] Chinese patent CN 222468197 U discloses an inlet filter for a coarse brine pressurization pump with a backwashing structure, which can realize online backwashing of the filter screen, ensuring the continuous and stable operation of the coarse brine pressurization pump and avoiding frequent manual cleaning of the filter screen. However, the structure is relatively complex and the operation of replacing the filter screen is cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a dilute phase suspension concentration device that has a simple structure, low cost, reduces labor intensity, and facilitates slag discharge and filter cloth replacement and maintenance.

[0006] To achieve the above objectives, the present invention provides a dilute phase suspension concentration device, comprising a water pump and a support. The water pump inlet is connected to a dilute phase suspension storage tank. A cylinder is connected to the support via a bracket. A drain port is provided on one side of the bottom of the cylinder. A cover plate and a bottom plate are connected to the top and bottom of the cylinder via quick-release buckles, respectively. A pressure relief valve and a liquid inlet are provided on the cover plate. The liquid inlet is connected to the water pump outlet. A slurry discharge port is connected to the bottom plate, and a slide valve is connected to the slurry discharge port. A permeable plate is connected inside the cylinder via a partition. A filter cloth is installed on the inner side of the permeable plate via a fixing ring.

[0007] As a further embodiment of this utility model, the quick-release buckle is a latch-type or clamp-type structure.

[0008] As a further embodiment of this utility model: the diameter of a single sieve hole in the permeable plate is 1mm to 5mm, and the opening rate is 40% to 80%.

[0009] As a further embodiment of this invention, the filter cloth has a pore size of 200 mesh to 800 mesh.

[0010] As a further embodiment of this utility model: the slide gate valve is a pneumatic or manual slide gate with a stroke of 50-100mm and a pressure resistance of 0.5MPa-1MPa.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: A water pump automatically feeds low-solids liquid into the filter through the inlet. The water pressure forces the liquid through the filter cloth, improving filtration efficiency. The filter cloth is fixed to the perforated plate. During slag discharge, the baffle valve is opened, pressurizing the material and causing it to be discharged through the slag outlet, achieving automatic slag discharge. This allows for cleaning of filter slag without disassembling the filter cloth, further improving discharge efficiency. Simultaneously, the water pump introduces cleaning fluid through the inlet to rinse the filter cloth, achieving automatic cleaning without disassembling it. To replace the filter cloth, simply open the quick-release clips and remove the filter cloth retaining ring. Operation is simple and convenient. This device has a simple structure, low cost, reduces labor intensity, and can meet the requirements of large-scale industrial production. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2As shown, the dilute phase suspension concentration device includes a water pump 1 and a support 12. The water pump 1 has a head of 20m-80m, preferably 40m. The inlet of the water pump 1 is connected to the dilute phase suspension storage tank. The solid particle content of the dilute phase suspension is 5%-40%. A cylinder 13 is connected to the support 12 via a support 8. A drain port 9 is provided on one side of the bottom of the cylinder 13. A cover plate 4 and a bottom plate 10 are respectively connected to the top and bottom of the cylinder 13 via quick-release buckles 5. The cylinder 13 is equipped with a pressure relief valve 2 and a liquid inlet 3. The liquid inlet 3 is connected to the outlet of the water pump 1. The bottom plate 10 is connected to a slurry discharge port 15, and a slide valve 16 is connected to the slurry discharge port 15. The cylinder 13 is connected to a permeable plate 7 through a partition 11. A filter cloth 14 is installed on the inner side of the permeable plate 7 through a fixing ring 6. The slide valve 16 is used to close the bottom of the cylinder 13, thereby using the permeable plate 7 and the filter cloth 14 to achieve the concentration and filtration of the dilute phase suspension.

[0017] To facilitate the disassembly and maintenance of the cover plate 4 and the base plate 10, the quick-release buckle 5 is a snap-on or clamp-type structure, ensuring that the disassembly and assembly time of the cover plate 4 or the base plate 10 is 0.5-3 minutes.

[0018] In order to meet the requirements of pressure bearing and high filtration area in pressurized filtration, the perforated plate 7 has a single sieve hole diameter of 1mm to 5mm and an opening rate of 40% to 80%. The perforated plate 7 is made of materials including but not limited to stainless steel, PVC, and PVDF. The sieve hole diameter is preferably 4mm, the opening rate is preferably 70%, and the material is preferably stainless steel.

[0019] To ensure the concentration and filtration effect, the filter cloth 14 has a pore size of 200 mesh to 800 mesh, and the material of the filter cloth 14 includes, but is not limited to, polypropylene, polyester, PPS, nylon, and PTFE. Preferably, the filter cloth 14 has a pore size of 500 mesh and is made of polyester.

[0020] Furthermore, the slide gate valve 16 is a pneumatic or manual slide gate with a stroke of 50-100mm and a pressure resistance of 0.5MPa-1MPa. Preferably, the stroke is 60mm and the pressure resistance is 0.5MPa.

[0021] The specific steps for using this utility model are as follows: Step 1: Automatic feeding. Close the pressure relief valve 2, turn on the power, and the dilute phase suspension enters the cylinder 13 through the water inlet 3 via the water pump 1 and the water inlet pipe. The water pressure in the cylinder 13 continuously increases, causing the clear liquid to pass through the filter cloth 14 and be discharged through the permeable plate 7 and the drain port 9.

[0022] Step 2: Automatic slag discharge. Turn off water pump 1, open pressure relief valve 2 to release pressure in cylinder 13, close drain port 9, open slide valve 16, and turn on water pump 1. The water pump 1 pressurizes the material so that it is discharged through slurry discharge port 15.

[0023] Step 3: Automatic cleaning of filter cloth 14. Water pump 1 is used to introduce cleaning solution into cylinder 13, and the cleaning solution is discharged through slurry outlet 15 to achieve automatic cleaning of filter cloth.

[0024] The third step is to adjust the liquid output. Adjust the operating frequency of water pump 1, which in turn adjusts the pressure in cylinder 13. When the liquid output is insufficient, increase the frequency to increase the pressure in cylinder 13 and increase the liquid flow rate; conversely, decrease the frequency to reduce the liquid flow rate.

[0025] Step 4: Replace filter cloth 14. Open the quick-release buckle 5 and remove the retaining ring 6 to quickly replace filter cloth 14.
