Description

Technical Field

[0001] The utility model relates to a capsule type filtering device. Background Art

[0002] At present, most capsule filter elements are made of a filter body as the core body and a shell. The shell of the product is made of hot-melt welding and cannot be disassembled. Due to the gap between the shell and the filter body, there is residual space inside the capsule filter element. Due to the high viscosity of the battery slurry, when replacing the capsule filter element, the shell is made of hot-melt welding and cannot be disassembled, so the filter element cannot be opened, and the remaining battery slurry inside the filter element cannot be quickly and effectively discharged. It is not convenient for the recycling of raw materials. In addition, the cost of battery slurry is high, which will cause great economic waste to the user.

[0003] In view of this, it is necessary to improve the existing capsule filter device to solve the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 to Figure 2 As shown, the capsule filter device 100 of the present invention comprises a capsule housing 1 and a filter element 2 arranged in the capsule housing 1 .

[0021] The capsule housing 1 includes an upper shell 11 and a lower shell 12 welded and fixed to the upper shell 11 .

[0022] A receiving space 114 is formed in the upper shell 11 , and the filter element 2 is disposed in the receiving space 114 . The lower shell 12 is welded to the upper shell 11 to close the receiving space 114 .

[0023] The lower shell 12 includes a fixing portion 121 connected to the upper shell 11 , a side wall 122 extending from the fixing portion 121 toward a direction away from the upper shell 11 , and an end cover 123 connected to one end of the side wall 122 away from the upper shell 11 .

[0024] The fixing portion 121 is fixed to one end of the upper shell 11 by welding.

[0025] The side wall 122 is recessed inward from the outer surface to form a cutting groove 1221. Since the fixing portion 121 is fixed to the lower shell 12 by welding, the cutting groove 1221 can be used to cut the lower shell 12 to expose the receiving space 114, so that the raw materials in the receiving space 114 can be discharged for recycling.

[0026] The cutting groove 1221 has a depth of 2.5 mm and a width of 1 mm. This data has been verified by theory and experiment to have no influence on the pressure bearing capacity and filtering performance of the capsule filter device 100, and the cutting groove 1221 under this data is the most convenient when the lower shell 12 is opened by circular cutting with a special tool.

[0027] The distance between the cutting groove 1221 and the end cover 123 is 5 mm. This distance is preferably such that the cutting groove 1221 is located in the middle of the side wall 122.

[0028] The end cover 123 is provided with a feed port 1231 and a discharge port 1232 . The filter element 2 and the upper shell 11 are both columnar. The discharge port 1232 is coaxially arranged with the filter element 2 and the upper shell 11 . The feed port 1231 and the discharge port 1232 are spaced apart.

[0029] The lower shell 12 further includes a discharge portion 1234 extending from the discharge port 1232 toward a direction away from the upper shell 11 , and a feed portion 1233 extending from the feed port 1231 toward a direction away from the upper shell 11 .

[0030] The feed portion 1233 and the discharge portion 1234 are both provided with O-rings 1235 to provide a seal when the feed portion 1233 and the discharge portion 1234 are connected to an external pipeline.

[0031] The end cover 123 is also provided with a shielding sheet 1236 for sealing the feed port 1231 and a sealing sheet 1237 for pressing the shielding sheet 1236 onto the feed port 1231 on the side facing the upper shell 11. In the absence of external force, the sealing sheet 1237 presses the shielding sheet 1236 onto the feed port 1231 to prevent the fluid in the receiving space 114 from overflowing. When the feed portion 1233 is connected to an external pipeline, the shielding sheet 1236 and the sealing sheet 1237 are opened under external force, so that the fluid can enter the receiving space 114.

[0032] The filter element 2 is provided with a receiving portion at one end facing the end cover 123, and the capsule filter device 100 further includes a sealing spring 1238 disposed in the receiving portion and a sealing plug 1239 abutting between the sealing spring 1238 and the discharge port 1232. External force pressing the sealing plug 1239 can compress the sealing spring 1238, so that the discharge port 1232 is exposed, and the fluid in the filter element 2 can be discharged from the discharge port 1232.

[0033] An exhaust port 111 is disposed at one end of the upper housing 11 away from the lower housing 12, and the capsule filter device 100 further includes an exhaust plug 112 for closing the exhaust port 111. A sealing ring 113 may also be disposed between the exhaust plug 112 and the exhaust port 111.

[0034] When in use, the capsule filter device 100 is installed in a dedicated filter, and the O-rings 1235 of the feed port 1231 and the discharge port 1232 of the lower shell 12 ensure the sealing of the installation; after installation, the sealing sheet 1237 and the shielding sheet 1236 of the feed port 1231 and the sealing plug 1239 of the discharge port 1232 are respectively pushed open by the ejector pin of the filter, and the exhaust plug 112 is unscrewed to allow the slurry to enter the filter element 2 through the feed port 1231 and discharge the air in the receiving space 114; when the slurry fills the receiving space 114, the exhaust plug 112 is installed, and the slurry passes through the filter element 2 from the outside to the inside under the action of the system pressure, impurities in the slurry are intercepted, and clean slurry is discharged from the discharge port 1232.

[0035] After use, the capsule filter device 100 is taken out from the dedicated filter, and the sealing sheet 1237 of the feed port 1231 and the sealing plug 1239 of the discharge port 1232 automatically seal the feed port 1231 and the discharge port under the action of elasticity to prevent slurry leakage; after taking out the capsule filter device 100, a dedicated tool is used to cut the lower shell 12 open by circumferentially cutting along the cutting groove 1221 of the lower shell 12, so that the raw material will be discharged from the opening of the lower shell 12, and the discharged raw material is recovered into a dedicated container.

[0036] The capsule filter device 100 of the utility model has a compact structure, is easy to install, and operates stably. It can ensure the sealing and pressure-bearing capacity of the capsule filter device 100. By setting the cutting groove 1221, the slurry raw material can be effectively recovered to reduce the waste of raw materials, and it has excellent economy.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
