Description

Technical Field

[0001] This utility model relates to the field of distillation kettle filtration technology, and in particular to a filtration device for the finished liquid product after distillation. Background Technology

[0002] The resource recovery workshop uses sorting and resource recovery technologies to classify and process waste, extracting valuable resources and thus achieving waste reuse. One method for reusing waste resources is to use a distillation kettle to distill the waste, thereby separating harmful components from recyclable substances.

[0003] The finished liquid obtained after distillation is difficult to control in terms of purity, resulting in a high level of impurities that fail to meet the required high purity. Furthermore, the impurities in the container adhere to the inner wall of the container, preventing its reuse and leading to resource waste. To address these issues, we designed a filtration device for the distilled finished liquid. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a filtration device for distilled finished liquid. By designing a multi-stage filtration system, the finished liquid after distillation is filtered to improve its purity. Furthermore, the quality of the finished liquid after distillation can be judged by observing the impurities on the filter cloth.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A device for filtering the finished liquid product after distillation, characterized in that it includes a primary filtration component, a secondary filtration component, and a container. The liquid outlet of the primary filtration component is connected to the liquid inlet of the secondary filtration component via a pipe, and the liquid outlet of the secondary filtration component is connected to the container via a flexible steel wire hose. The secondary filtration component and the primary filtration component have the same structure.

[0007] The primary filtration assembly consists of a filter barrel, a lid, and filter elements. The lid is installed at the top opening of the filter barrel. The filter elements are located inside the filter barrel and include a filter bag frame, a filter bag, a filter bag retaining ring, and a rubber ring. The filter bag is fitted over the filter bag frame. The opening of the filter bag is located between the filter bag retaining ring and the end portion of the filter bag frame. The filter bag retaining ring is fixedly connected to the end portion of the filter bag frame with bolts. A rubber ring is provided between the filter bag retaining ring and the filter bag.

[0008] The filter barrel has a retaining ring on its inner wall. The inner diameter of the retaining ring is smaller than the diameter of the filter bag fixing ring, and the inner diameter of the retaining ring is larger than the diameter of the filter bag skeleton. This allows the filter bag fixing ring to be engaged with the retaining ring inside the filter barrel, thus completing the installation of the filter element.

[0009] The inner diameter of the filter bag retaining ring is larger than the diameter of the filter bag frame, while the inner diameter of the filter bag retaining ring is smaller than the diameter at the end of the filter bag frame. This allows the filter bag retaining ring to be fitted onto the filter bag frame from the bottom, and then bolted to the end of the filter bag frame, pressing the filter bag opening tightly between the filter bag retaining ring and the end of the filter bag frame.

[0010] The filter bag frame is a cylindrical structure assembled and welded from multiple stainless steel pipes, and the lower part of the port of the filter bag frame is set in an arc shape, which makes it easy for the filter bag to stick tightly to the filter bag frame and be fixed by the filter bag fixing ring.

[0011] Furthermore, the inlet and outlet of the filter barrel are connected to the pipeline via connecting flanges, and a filter cloth is provided between the two connecting flanges to further enhance the filtration effect on the finished liquid.

[0012] Furthermore, the filter canister is mounted on the ground via a support frame.

[0013] The beneficial effects of this utility model are:

[0014] This invention improves the purity of the distilled liquid by using a primary and a secondary filtration assembly to perform multi-stage filtration. Both the inlet and outlet ends of the filtration assembly are equipped with filter cloths, which are clamped and fixed between two sets of connecting flanges used for pipe connection. The filter cloth at the connection between the secondary filtration assembly and the container can be removed for observation. The impurities on the filter cloth can be checked by visual inspection or by using a microscope to determine whether repeated filtration is necessary until the impurities are basically eliminated, thus completing the filtration operation.

[0015] This utility model designs a filter assembly that uses a filter bag set fixed to a filter bag frame. The filter bag is opened by the filter bag frame, and the finished liquid is transported into the filter bag. The liquid filtered by the filter bag is discharged, while impurities are left inside the filter bag. Moreover, the filter element is clipped into the filter barrel, which makes the disassembly and cleaning of the filter bag very convenient. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1

[0023] As shown in the figure, the liquid outlet of the primary filter assembly 101 is connected to the liquid inlet of the secondary filter assembly 102 via a pipe. The liquid outlet of the secondary filter assembly 102 is connected to the container 9 via a flexible steel hose 8. The secondary filter assembly 102 and the primary filter assembly 101 have the same structure.

[0024] The primary filtration assembly 101 consists of a filter barrel 1, a lid 2, and filter elements. The lid 2 is installed at the top opening of the filter barrel 1. The filter elements are installed inside the filter barrel 1. The filter elements include a filter bag frame 31, a filter bag 32, a filter bag fixing ring 33, and a rubber ring 35. The filter bag 32 is fitted onto the outside of the filter bag frame 31. The opening of the filter bag 32 is located between the filter bag fixing ring 33 and the port portion 311 of the filter bag frame 31. The filter bag fixing ring 33 is fixedly connected to the port portion 311 of the filter bag frame 31 by bolts 34. A rubber ring 35 is provided between the filter bag fixing ring 33 and the opening of the filter bag 32.

[0025] The filter barrel 1 has a retaining ring 4 on its inner wall. The inner diameter of the retaining ring 4 is smaller than the diameter of the filter bag fixing ring 33, and the inner diameter of the retaining ring 4 is larger than the diameter of the filter bag skeleton 31, so that the filter bag fixing ring 44 is locked on the retaining ring 4 inside the filter barrel 1, thus completing the installation of the filter element.

[0026] The inner diameter of the filter bag retaining ring 33 is set to be larger than the diameter of the filter bag frame 31, and smaller than the diameter at the port 311 of the filter bag frame 31. This allows the filter bag retaining ring 33 to be inserted from the lower end of the filter bag frame 31 after the filter bag 32 is fitted onto it, then moved upwards to the port 311 of the filter bag frame 31, and finally secured to the port 311 of the filter bag frame 31 with bolts 34. This presses the opening of the filter bag 32 tightly between the filter bag retaining ring 33 and the port 311 of the filter bag frame 31.

[0027] The filter bag frame 31 is a cylindrical structure assembled and welded from multiple stainless steel pipes. The lower part of the port 211 of the filter bag frame 21 is set as an arc shape, which makes it easy for the filter bag 32 to stick tightly to the filter bag frame and be fixed by the filter bag fixing ring 33.

[0028] Furthermore, the filter bucket 1 is installed on the ground via a support frame 7. The inlet end 11 and outlet end 12 of the filter bucket 1 are connected to the pipeline via connecting flanges 5, and a filter cloth 6 is provided between the two connecting flanges 5 to further enhance the filtration effect on the finished liquid.

[0029] Example 2

[0030] In use, the finished liquid obtained after distillation in the distillation vessel is first stored in a temporary storage tank. This temporary storage tank is connected to the inlet of the primary filtration assembly 101 through a pipe, so that the finished liquid 100 to be filtered enters from the inlet 11 of the filter barrel 1 of the primary filtration assembly 101. The finished liquid 100 to be filtered undergoes multiple filtrations through multiple layers of filter cloth 6 and filter bags 32 in the two-stage filtration assembly, thereby improving the purity of the finished liquid after distillation.

[0031] The filter cloth 6 is clamped and fixed between the two sets of connecting flanges 5 used for pipe connection. After each filtration, the finished liquid 100 flows into the container 9. The filter cloth 6 at the connection between the secondary filtration component 102 and the container 9 can be removed for observation. The condition of impurities on the filter cloth can be checked by visual inspection or by using a microscope to determine whether filtration needs to be repeated. Before repeated filtration, the filter cloth 6 used for the last layer of filtration needs to be cleaned after observation and then installed back between the two sets of connecting flanges 5. The remaining filter cloths 6 and filter bags 32 can be cleaned by the user according to their own judgment. Repeat filtration until there are basically no impurities, and the filtration operation is completed.

[0032] The filter bag 32 in the filter element is fixedly mounted on the filter bag frame 31. The filter bag frame 31 opens the filter bag 32, and the finished liquid 100 is delivered into the filter bag 32. The liquid filtered by the filter bag 32 enters the filter tank 1, while the filtered impurities are retained in the filter bag 32. The filter element is fastened to the retaining ring 4 set in the filter tank 1 by the filter bag fixing ring 33. During cleaning, simply open the tank cover 2, pull out the filter bag frame 31 and the filter bag 32, and remove the filter bag 32 for cleaning. The operation is convenient.
