Description

Technical Field

[0001] This utility model relates to the field of water tank cleaning technology, and more specifically, to a water tank structure that uses water for heat preservation. Background Technology

[0002] In the coating industry, many commonly used batch parts (such as conveyor belt hangers) come into contact with different colors of paint and powder during the production process. These paints can solidify on the parts, affecting the overall appearance, and need to be cleaned.

[0003] Because some cleaning solutions are more effective when heated, they need to be heated. However, some existing cleaning tanks have heating elements that come into direct contact with the cleaning solution. This method has the following drawbacks: firstly, direct contact between the heating element and the cleaning solution poses a safety hazard; secondly, if the cleaning solution is corrosive, it will corrode the heating element, thus affecting its service life; and thirdly, impurities generated by components during the cleaning process are difficult to remove in a timely manner.

[0004] Therefore, a water tank structure using water insulation is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water tank structure that uses water for insulation.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A water tank structure using water insulation includes an outer casing and a heat-conducting inner casing disposed within the outer casing. A gap exists between a portion of the outer side wall of the inner casing and a portion of the inner side wall of the outer casing. A heating element is disposed on the outer casing, and the heating section of the heating element extends between the outer side wall of the inner casing and the inner side wall of the outer casing. A slag collection box is disposed on the outer side wall of the outer casing, and a slag collection mechanism is disposed within the inner casing for feeding solid particles generated during the cleaning process into the slag collection box.

[0008] Furthermore, in this utility model, the slag collection mechanism includes at least two filter plates that rotate synchronously and have different filtration capacities, as well as a flipping mechanism and a guiding mechanism both disposed within the inner box. The two filter plates are rotatably disposed within the inner box at intervals, and both filter plates are connected to the flipping mechanism in a transmission manner. The two filter plates have two states: horizontal and vertical. When neither of the two filter plates is in a horizontal state, the solid particles on the two filter plates can fall into the slag collection box through the guiding mechanism.

[0009] Furthermore, in this utility model, two rotating shafts are rotatably arranged at intervals inside the inner box, and the two filter plates are respectively fixedly connected to the two rotating shafts; the flipping mechanism includes a drive motor that is pulsatorically connected to one of the rotating shafts, and a connecting rod, which is respectively hinged to the two filter plates; when both filter plates are in a vertical state, the connecting rod is also in a vertical state.

[0010] Furthermore, in this utility model, the inner box has two through holes spaced one above the other on the side near the slag collection box, and both through holes communicate with the slag collection box; the guiding mechanism includes two inclined plates disposed at an angle inside the inner box, and a sealing mechanism disposed in each of the two through holes, the two through holes being lower than the connection between the corresponding filter plate and the rotating shaft in the vertical direction, and the top of any of the inclined plates being located below the connection between the corresponding filter plate and the rotating shaft, and the bottom of any of the inclined plates being disposed in the corresponding through hole; the sealing mechanism is used to open or close the through holes.

[0011] Furthermore, in this utility model, any of the above-mentioned sealing mechanisms includes an electric push rod disposed in the inner box and a sealing plate disposed at the actuating end of the electric push rod. The end of the sealing plate away from the electric push rod can abut against the corresponding inclined plate. When the sealing plate abuts against the corresponding inclined plate, the solid particles on the corresponding filter plate cannot fall into the slag collection box through the through hole.

[0012] Furthermore, in this utility model, any of the above-mentioned inclined plates are provided with a plurality of water passage holes.

[0013] Furthermore, in this utility model, a partition is provided inside the slag collection box, and the partition is located between the two through holes.

[0014] Furthermore, in this utility model, when both of the above-mentioned filter plates are in a horizontal position, the side of any of the above-mentioned filter plates abuts against the inner wall of the inner box.

[0015] The beneficial effects of this utility model are:

[0016] 1. There is a gap between part of the outer side wall of the inner chamber and part of the inner side wall of the outer chamber. The heating section of the heating element extends between the outer side wall of the inner chamber and the inner side wall of the outer chamber. In this way, when heating the cleaning fluid, the cleaning fluid will not come into direct contact with the heating element, thereby extending the service life of the heating element.

[0017] 2. By installing a slag collection mechanism inside the inner box, it is convenient to place the parts to be cleaned; on the other hand, the design of the filter plate can intercept most of the impurities generated during the cleaning process of the parts, so the amount of solid particles deposited at the bottom of the inner box will be greatly reduced, thereby reducing the workload of cleaning the inner box; after the cleaning liquid is discharged, the filter plate is flipped at a certain angle, and the impurities on the filter plate will fall into the slag collection box for easy collection.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A water tank structure using water insulation includes an outer casing 101 and a thermally conductive inner casing 201 installed inside the outer casing 101. Water is filled into the outer casing 101, and cleaning fluid is filled into the inner casing 201. A gap exists between a portion of the outer side wall of the inner casing 201 and a portion of the inner side wall of the outer casing 101. A heating element 301 is installed on the outer casing 101, with its heating section extending between the outer side wall and the inner side wall of the inner casing 201. This design prevents direct contact between the cleaning fluid and the heating element 301 when heating the cleaning fluid. The heating element 301 first heats the water in the outer casing 101; the increased water temperature then transfers heat to the cleaning fluid through the inner casing 201, thus heating the cleaning fluid. The parts to be cleaned can then be immersed in the inner casing 201 for a period of time before being removed.

[0027] During the immersion of parts in a cleaning solution at a certain temperature, some impurities on the surface of the parts to be cleaned will be dissolved. If these impurities are not cleaned in time, they will accumulate at the bottom of the inner box 201, making them difficult to clean. To solve this problem, a slag collection box 401 is installed on the outer wall of the outer box 101, and a slag collection mechanism is installed inside the inner box 201 to send solid particles (impurities) generated during the cleaning process into the slag collection box 401.

[0028] Specifically, refer to Figures 2-4 In this embodiment, the slag collection mechanism includes at least two synchronously rotating filter plates 501, as well as a rotating mechanism and a guiding mechanism both installed within the inner housing 201. Figure 2 or Figure 3 From the perspective of the rotating mechanism, both filter plates 501 can be rotated from a horizontal to a vertical position. To ensure that the cleaning fluid can pass smoothly through both filter plates 501 during operation, the filtration capacity of the upper filter plate 501 is less than that of the lower filter plate 501 in this embodiment. Thus, when the parts to be cleaned are placed on the upper filter plate 501 for immersion cleaning, larger diameter impurities remain on the upper filter plate 501, while smaller diameter impurities fall onto the lower filter plate 501.

[0029] from Figure 2 or Figure 3 From the perspective of the inner housing 201, to facilitate the installation of the two filter plates 501, two rotating shafts 502 are installed at an interval, one above the other. The two filter plates 501 are fixedly connected to the two rotating shafts 502 respectively. One end of the upper rotating shaft 502 is connected to a drive motor 503. The right ends of the two filter plates 501 are connected by a connecting rod 504, which is hinged to the two filter plates 501 respectively. When both filter plates 501 are in a vertical position, the connecting rod 504 is also in a vertical position.

[0030] Thus, when the two filter plates 501 need to be rotated from a horizontal position to a vertical position, that is, from... Figure 2 The state changes to Figure 3 When in the vertical position, the drive motor 503 works, causing the upper rotating shaft 502 to rotate counterclockwise, and the upper filter plate 501 to rotate clockwise in sync. The lower filter plate 501 also rotates counterclockwise in sync under the drive of the connecting rod 504, until both filter plates 501 are in a vertical position.

[0031] Reference Figure 2 It is important to note that, in order for the upper filter plate 501 to completely intercept larger diameter impurities and prevent them from falling onto the lower filter plate 501 and clogging the filter holes, and for the lower filter plate 501 to intercept smaller diameter impurities passing through the upper filter plate 501 and prevent them from settling at the bottom of the inner chamber 201 and increasing the workload of cleaning the inner chamber 201, in the actual design, when both filter plates 501 are in a horizontal position, the side of either filter plate 501 abuts against the inner wall of the inner chamber 201. Under the action of the two inclined plates 701, impurities intercepted by the upper filter plate 501 cannot fall onto the lower filter plate 501; and impurities intercepted by the lower filter plate 501 cannot fall to the bottom of the inner chamber 201.

[0032] The design of the two filter plates 501 can intercept most of the impurities generated during the cleaning process of the parts, which will greatly reduce the amount of solid particles deposited at the bottom of the inner box 201, thereby reducing the workload of cleaning the inner box 201.

[0033] To facilitate the entry of impurities from the two filter plates 501 into the slag collection box 401, in this embodiment, two through holes 601 are spaced one above the other on the side of the inner box 201 near the slag collection box 401. Both through holes 601 penetrate the outer box 101 and communicate with the slag collection box 401. The guiding mechanism includes two inclined plates 701 installed at an angle within the inner box 201, and sealing mechanisms installed in the two through holes 601 respectively. Each of the two inclined plates 701 has several water passage holes. The vertical position of each through hole 601 is lower than the connection point between the corresponding filter plate 501 and the rotating shaft 502, and the top of any inclined plate 701 is below the connection point between the corresponding filter plate 501 and the rotating shaft 502, while the bottom end of any inclined plate 701 extends into the corresponding through hole 601. (Refer to...) Figures 2-4The arbitrary sealing mechanism includes an electric actuator 702 installed inside the inner housing 201 and a sealing plate 703 installed at the actuating end of the electric actuator 702. The extension and retraction direction of the electric actuator 702 is vertical. The sealing plate 703 is located above the through hole 601. The end of the sealing plate 703 away from the electric actuator 702 is provided with an inclined surface with the same inclination angle as the inclined plate 701, so that the end of the sealing plate 703 away from the electric actuator 702 can abut against the inclined plate 701. When the sealing plate 703 abuts against the corresponding inclined plate 701, it blocks the through hole 601.

[0034] from Figure 2 or Figure 3 From the perspective of the filter plate, since the upper filter plate 501 intercepts larger diameter impurities and the lower filter plate 501 intercepts smaller diameter impurities, if the impurities on the upper filter plate 501 fall into the slag collection box 401 and accumulate to a certain depth, blocking the lower through hole 601, then the impurities on the lower filter plate 501 cannot enter the slag collection box 401 through the lower through hole 601. Therefore, to solve this problem, in this embodiment, a partition plate 801 is installed in the middle of the slag collection box 401, located between the two through holes 601. In this way, the partition plate 801 will intercept the impurities falling from the upper filter plate 501, preventing them from blocking the lower through hole 601.

[0035] Working principle:

[0036] from Figure 2 or Figure 3 From the perspective of the process, before immersing the parts to be cleaned, the two electric actuators 702 first control the two sealing plates 703 to move downwards until they abut against the inclined plate 701, thus preventing the cleaning fluid in the inner chamber 201 from flowing into the slag collection box 401. Then, water is injected into the outer chamber 101, and the cleaning fluid is injected into the inner chamber 201. The heating element 301 first heats the water in the outer chamber 101; as the water temperature rises, its heat is transferred to the cleaning fluid through the inner chamber 201, thus heating the cleaning fluid. Next, the drive motor 503 operates to control the rotation of the upper shaft 502 until both filter plates 501 are in a horizontal position, facilitating the placement of the parts to be cleaned on the upper filter plate 501. It is important to note that when both filter plates 501 are in a horizontal position, the cleaning fluid in the inner chamber 201 must completely submerge the upper filter plate 501. The parts to be cleaned are then placed on the upper filter plate 501 and soaked for a period of time before being removed.

[0037] When the cleaning fluid is changed, impurities on the surface of the components remain on the two filter plates 501 after the cleaning fluid is drained. This causes the two electric actuators 702 to shorten, and the two sealing plates 703 to move upwards, opening the two through holes 601. Then, the drive motor 503 operates, controlling the upper rotating shaft 502 to rotate until the two filter plates 501 are in a vertical position. The impurities on the two filter plates 501 then fall onto the two inclined plates 701 under the influence of gravity. The impurity particles on the inclined plates 701 then fall into the slag collection box 401 under the influence of inertia and gravity.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
