Description

Technical Field

[0001] This utility model relates to the technical field of shoe sole production equipment, specifically to a circulating filtration device for a chemical soaking machine. Background Technology

[0002] Adhesive bonding is an important step in shoe manufacturing. Current bonding processes involve soaking the sole in a chemical solution, which is then fully adhered to the surface of the sole. After soaking, the sole is heated in an oven and irradiated with ultraviolet light. The chemical solution on the surface of the sole undergoes a chemical reaction, which increases the polarity of the sole surface (the difference between positive and negative charges on the sole surface), thereby increasing viscosity and adhesion.

[0003] In the process of soaking shoe sole materials in a soaking tank with UV-curing adhesive, the solvent and solid components of the UV-curing adhesive often react chemically with the shoe material and release agent, and impurities are introduced, resulting in sediment. If these sediments are not treated, the soaked shoe soles will develop yellowing defects. The existing treatment method is to have an outlet at the bottom of the soaking tank connected to a filtration and circulation system. The filtration and circulation system filters and recycles the UV-curing adhesive with accumulated sediment. However, the outlet occupies a relatively small area at the bottom of the soaking tank, and the sediment accumulated at the bottom of the soaking tank, which is relatively far from the outlet, cannot flow into the filtration and circulation system through the outlet, resulting in a relatively poor filtration effect.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0005] The purpose of this invention is to provide a circulating filtration device for a medicine soaking machine with relatively high filtration efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A circulating filtration device for a medicinal soaking machine includes a frame with a soaking tank on the frame. A settling trough, arranged along the width of the soaking tank, is located at the center of the bottom of the soaking tank. One end of the settling trough extends to one side of the width of the soaking tank, and the other end extends to the other side of the width of the soaking tank. The bottom of the soaking tank slopes downwards from both ends towards the settling trough, and the depth of the settling trough gradually increases from one end to the other. An external water tank is located outside the soaking tank on the side corresponding to the end with the greatest depth of the settling trough. A notch is formed at the bottom of the side wall of the end with the greatest depth of the settling trough, connecting the settling trough and the external water tank. A water outlet pipe is connected to the bottom of the external water tank, and the connection point between the water outlet pipe and the external water tank is close to the notch. A water pipe is connected to a first connecting pipe and a second connecting pipe via a three-way valve. The end of the first connecting pipe not connected to the three-way valve is suspended. A first control valve is installed on the first connecting pipe. A filter assembly is connected to the end of the second connecting pipe not connected to the three-way valve. A second control valve is installed on the second connecting pipe. The filter assembly includes a Y-type filter, a diaphragm pump, a first oil removal filter, and a second oil removal filter. The inlet of the Y-type filter is connected to the end of the second connecting pipe not connected to the three-way valve. The outlet of the Y-type filter is connected to the inlet of the diaphragm pump. The outlet of the diaphragm pump is connected to the inlet of the first oil removal filter. The outlet of the first oil removal filter is connected to the inlet of the second oil removal filter. The outlet of the second oil removal filter is connected to the soaking tank via a third connecting pipe. A third control valve is installed on the third connecting pipe.

[0007] As an improvement of this utility model, the third connecting pipe is connected to a fourth connecting pipe at a position between the outlet of the third control valve and the outlet of the second oil removal filter. The end of the fourth connecting pipe that is not connected to the third connecting pipe is connected to a medicine tank, and a fourth control valve is provided on the fourth connecting pipe.

[0008] As an improvement of this utility model, the first oil removal filter includes a vertically arranged first cylinder and a first filter bag disposed in the first cylinder. The first cylinder has a first collection chamber formed below the first filter bag. The outlet of the first oil removal filter is located on the side wall of the first collection chamber and communicates with the first collection chamber. A first drain pipe communicating with the first collection chamber is connected to the side wall of the first cylinder. The horizontal position of the connection between the first drain pipe and the first cylinder is lower than the horizontal position of the outlet of the first oil removal filter. A fifth control valve is provided on the first drain pipe.

[0009] As an improvement of this utility model, the second oil removal filter includes a vertically arranged second cylinder and a second filter bag disposed in the second cylinder. The second cylinder has a second collection chamber formed below the second filter bag. The outlet of the second oil removal filter is located on the side wall of the second collection chamber and communicates with the second collection chamber. A second drain pipe communicating with the second collection chamber is connected to the side wall of the second cylinder. The horizontal position of the connection between the second drain pipe and the second cylinder is lower than the horizontal position of the outlet of the second oil removal filter. A sixth control valve is provided on the second drain pipe.

[0010] As an improvement of this utility model, both the first oil removal filter and the second oil removal filter are bag filters.

[0016] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The terms "first," "second," "third," "fourth," "fifth," and "sixth," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0018] like Figure 1 As shown, this embodiment provides a circulating filtration device for a medicine soaking machine, including a frame (not shown in the figure), on which a soaking tank 10 is provided. A settling trough 11 is provided at the bottom of the soaking tank 10 along the width direction of the soaking tank 10. One end of the settling trough 11 extends to one side of the width direction of the soaking tank 10, and the other end of the settling trough 11 extends to the other side of the width direction of the soaking tank 10. The bottom of the soaking tank 10 is arranged to gradually slope downward from both ends toward the settling trough. The depth of the settling trough 11 gradually increases from one end to the other end. An external water tank 20 is provided on the side of the soaking tank 10 corresponding to the end with the greatest depth of the settling trough 11. The external water tank 20 is located outside the soaking tank. In this embodiment, the soaking tank 10 is a stainless steel soaking tank, and the external water tank 20 is a stainless steel external water tank. A notch is opened at the bottom of the side wall of the end with the greatest depth of the settling trough 11 to connect the settling trough 11 and the external water tank 20. In this example, the bottom of the external water tank 20 is flush with the deepest part of the bottom of the settling trough 11.

[0019] The bottom of the external water tank 20 is connected to a water outlet pipe 21. The connection point between the water outlet pipe 21 and the external water tank 20 is close to a notch. The water outlet pipe 21 is connected to a first connecting pipe 22 and a second connecting pipe 23 via a three-way valve. The end of the first connecting pipe 22 not connected to the three-way valve is suspended. A first control valve 24 is installed on the first connecting pipe 22. The end of the second connecting pipe 23 not connected to the three-way valve is connected to a filter assembly. A second control valve 25 is installed on the second connecting pipe 23. The filter assembly includes a Y-type filter 30, a diaphragm pump 31, a first oil removal filter 32, and a second oil removal filter 33. The first oil removal filter 32 and the second oil removal filter 33... All filters 32 are bag filters. It should be noted that these are conventional bag filters, and will not be described in detail here. The inlet of the Y-type filter 30 is connected to the end of the second connecting pipe 23 that is not connected to the three-way valve. The outlet of the Y-type filter 30 is connected to the inlet of the diaphragm pump 31. The Y-type filter 30 effectively prevents foreign objects from being sucked into the diaphragm pump 31 and damaging its diaphragm. The outlet of the diaphragm pump 31 is connected to the inlet of the first oil removal filter 32. The outlet of the first oil removal filter 32 is connected to the inlet of the second oil removal filter 33. The outlet of the second oil removal filter 33 is connected to... The soaking tank 10 is connected, and a third control valve 35 is installed on the third connecting pipe 34. Before use, UV solution is added to the soaking tank 10. After a period of use, the UV solution in the soaking tank 10 produces sediment. Due to gravity, the sediment slowly accumulates at the bottom of the soaking tank 10. The UV solution containing sediment flows through the settling tank 11 and the notch into the external water tank 20 due to gravity. The UV solution containing sediment in the external water tank 20 is pumped by the diaphragm pump to the Y-type filter 30, the first oil removal filter 32, and the second oil removal filter 33 for filtration. The filtered UV solution then passes through... The third connecting pipe 34 delivers the material to the soaking tank 10, and this cycle repeats. By providing a settling tank 11 and an external water tank 20 connected to the settling tank 11 at the bottom of the soaking tank 10, the sediment accumulated at the bottom of the soaking tank 10 can flow from shallow to deep along the settling tank 11 to the external water tank 20, and finally flow into the filter assembly for filtration. The filtration effect is relatively high. Sediment that does not flow into the outlet pipe for filtration will accumulate at the bottom of the external water tank 20. When the sediment needs to be cleaned, it can be cleaned directly through the opening of the external water tank 20. The operation is simple and convenient.

[0020] The third connecting pipe 34 is connected to a fourth connecting pipe 36 at a position between the outlet of the third control valve 35 and the outlet of the second oil removal filter 33. The end of the fourth connecting pipe 36 that is not connected to the third connecting pipe 34 is connected to a medicine tank 37. A fourth control valve 38 is provided on the fourth connecting pipe 36. Through the cooperation of the fourth connecting pipe 36 and the fourth control valve 38, the operator can store the filtered UV medicine in the medicine tank 27.

[0021] The first oil removal filter 32 includes a vertically arranged first cylinder and a first filter bag disposed within the first cylinder. A first collection chamber 39 is formed in the first cylinder below the first filter bag. The outlet of the first oil removal filter 32 is located on the side wall of the first collection chamber 39 and communicates with the first collection chamber 39. A first drain pipe 40 communicating with the first collection chamber 39 is connected to the side wall of the first cylinder. The horizontal position of the connection between the first drain pipe 40 and the first cylinder is lower than the horizontal position of the outlet of the first oil removal filter 32. A fifth control valve 41 is provided on the first drain pipe 40. By opening the fifth control valve 41 on the first drain pipe 40, the residual chemical solution of the first oil removal filter 32 can be discharged.

[0022] The second oil removal filter 33 includes a vertically arranged second cylinder and a second filter bag disposed within the second cylinder. A second collection chamber 42 is formed in the second cylinder below the second filter bag. The outlet of the second oil removal filter 33 is located on the side wall of the second collection chamber 42 and communicates with the second collection chamber 42. A second drain pipe 43 communicating with the second collection chamber 42 is connected to the side wall of the second cylinder. The horizontal position of the connection between the second drain pipe 43 and the second cylinder is lower than the horizontal position of the outlet of the second oil removal filter 33. A sixth control valve 44 is provided on the second drain pipe 43. By opening the sixth control valve 44 on the second drain pipe 43, the residual chemical solution of the second oil removal filter 33 can be discharged.
