[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0040] like Figures 1-7 As shown:

[0041] An embodiment of this application provides an edible oil filter screen cleaning device, which includes an ultrasonic cleaning tank 1 and a frame 3. The frame 3 is provided with a lifting frame 4 that can move up and down, and the lower end of the lifting frame 4 is provided with a hoisting frame 5 that can move in the horizontal direction and can hoist multiple filter screens 13 at the same time.

[0042] In this embodiment, the lifting frame 4 moves horizontally in the left-right direction.

[0043] The hoisting frame 5 can be moved into the ultrasonic cleaning tank 1.

[0044] The ultrasonic cleaning tank 1 is connected to a heating device 2 that forms a circulating water circuit with it and is used to heat the water.

[0045] In this embodiment, a bracket is fixed to the lower end of the ultrasonic cleaning tank 1, and a drain pipe 7 with a valve is connected to the lower end of the ultrasonic cleaning tank 1 to discharge the cleaning wastewater in the ultrasonic cleaning tank 1. An inlet pipe 8 connected to a water source is connected to the upper part of the ultrasonic cleaning tank 1.

[0046] In use, a certain amount of clean water is injected into the ultrasonic cleaning tank 1 through the water inlet pipe 8, allowing the clean water to circulate between the ultrasonic cleaning tank 1 and the heating device 2. The heating device 2 heats the clean water in the ultrasonic cleaning tank 1. While heating the clean water, the hoisting frame 5 is moved to the side of the ultrasonic cleaning tank 1, and the operator manually hangs the filter screen 13 to be cleaned on the hoisting frame 5. When the clean water in the ultrasonic cleaning tank 1 boils, the circulation of clean water is stopped, and then the hoisting frame 5 is moved upward, causing the filter screen 13 to move upward. When the lower end of the filter screen 13 is above the ultrasonic cleaning tank 1, the upward movement of the hoisting frame 5 is stopped, and then the hoisting frame 5 is moved above the ultrasonic cleaning tank 1. Then the hoisting frame 5 is moved downward, moving the filter screen 13 into the ultrasonic cleaning tank 1. When the filter screen 13 is completely immersed in the clean water in the ultrasonic cleaning tank 1, the downward movement of the hoisting frame 5 is stopped. At this point, the filter screen 13 can be ultrasonically cleaned in the ultrasonic cleaning tank 1.

[0047] After cleaning, move the hoisting frame 5 upwards and move the filter screen 13 above the ultrasonic cleaning tank 1 for draining. After draining, move the hoisting frame 5 to the side of the ultrasonic cleaning tank 1 and remove the filter screen 13.

[0048] When cleaning the next batch of filter screens 13, first drain the cleaning wastewater from the ultrasonic cleaning tank 1 through the drain pipe 7, and then add clean water again to carry out the cleaning work.

[0049] The edible oil filter screen cleaning device provided in this embodiment includes an ultrasonic cleaning tank 1 and a frame 3. The frame 3 is equipped with a lifting frame 4 that can move up and down. The lower end of the lifting frame 4 is equipped with a hoisting frame 5 that can move horizontally and simultaneously suspend multiple filter screens 13. The hoisting frame 5 can move into the interior of the ultrasonic cleaning tank 1. The ultrasonic cleaning tank 1 is connected to a heating device 2 that forms a circulating water circuit with it and is used to heat the water. In use, the hoisting frame 5 can simultaneously move multiple filter screens 13 into the ultrasonic cleaning tank 1 and use hot water to perform ultrasonic cleaning on the filter screens 13. Thus, while ensuring the cleaning effect of the filter screens 13, batch cleaning of the filter screens 13 is possible, which not only reduces the labor intensity of the workers, but also improves the cleaning efficiency of the filter screens 13.

[0050] In some embodiments of this application, the lifting frame 4 includes a horizontal column I 401, both ends of which are fixedly connected to a horizontal column II 402 perpendicular to it, and both ends of the horizontal column II 402 are fixedly fitted with a sliding sleeve 403.

[0051] In this embodiment, the horizontal columns I 401 are distributed along the left and right direction, and horizontal columns II 402 are provided at the left and right ends of the horizontal columns. Sliding sleeves 403 are provided at the front and rear ends of the horizontal columns II 402.

[0052] The frame 3 includes a top frame 301. Four uprights 302 are fixed to the lower end of the top frame 301, each penetrating through one of the four sliding sleeves 403 and slidably connected to the sleeves 403. Specifically, one upright 302 penetrates one sliding sleeve 403, and the outer wall of the upright 302 contacts and slidably connects to the inner wall of the sliding sleeve 403. The top frame 301 has a rectangular frame structure, with uprights 302 positioned at each of the four corners of its lower end.

[0053] A horizontal bar 303, fixed to the column 302, is provided below the horizontal column II 402. A vertically distributed hydraulic cylinder I 11, connected to the horizontal column II 402, is fixed at the upper end of the horizontal bar 303. Specifically, a connecting seat is hinged to the free end of the hydraulic cylinder via a pin, and the connecting seat is fixedly connected to the lower end of the horizontal column II 402.

[0054] In this embodiment, a hydraulic station (not shown in the figure) is also included. The hydraulic station is connected to two hydraulic cylinders I11 simultaneously, and the hydraulic station controls the two hydraulic cylinders to extend and retract synchronously. The hydraulic station and the method by which the hydraulic station controls the synchronous extension and retraction of the two hydraulic cylinders are existing technologies and will not be described in detail. The column 302 is fixed to the ground by embedded parts.

[0055] In use, the operator controls the hydraulic station. After the hydraulic station controls the two hydraulic cylinders I11 to extend synchronously, the lifting frame 4 moves upward. After the hydraulic station controls the two hydraulic cylinders I11 to retract synchronously, the lifting frame 4 moves downward, thereby realizing the up and down movement of the lifting frame 4.

[0056] In some embodiments of this application, a tensioning device 6 is connected between two sliding sleeves 403 located on the same side of the frame 3 to balance the force on the sliding sleeves 403. The tensioning device 6 consists of two tensioning structures.

[0057] The tensioning structure includes vertically distributed turnbuckles 601, pulley I 602, and two pulleys II 603 located in the same straight line.

[0058] In this embodiment, the lower end of the turnbuckle 601 has an O-shaped structure, and the upper end of the turnbuckle 601 has a C-shaped structure.

[0059] The upper end of the turnbuckle 601 is connected to the lower part of one of the sliding sleeves 403. The lower end of the turnbuckle 601 is connected to a steel rope 604. The steel rope 604 first extends downward, then passes around pulley I 602 and extends upward, then passes around two pulleys II 603 and extends downward to the upper part of another sliding sleeve 403 and connects to the upper part of the sliding sleeve 403. Specifically, pulley I 602 is rotatably connected to support I via bearings. Support I is fixed to the lower part of the column 302 located on the same side as it. Pulley II 603 is rotatably connected to support II via bearings. Support II is fixed to the top of the frame 3.

[0060] In this embodiment, a connecting ear I 605 is fixed to the upper part of the sliding sleeve 403, and a connecting ear II 606 is fixed to the lower part of the sliding sleeve 403. Both connecting ear I 605 and connecting ear II 606 have connecting holes. The upper end of the basket structure passes through the connecting hole of the connecting ear II 606 and hangs on the connecting hole. One end of the steel rope 604 passes through the lower end of the turnbuckle 601 and is fixed to the lower end of the turnbuckle 601 by the U-shaped clamp 607. The other end of the steel rope 604 passes through the connecting hole of the corresponding connecting ear I 605 and is fixed to the corresponding connecting ear I 605 by the U-shaped clamp 607.

[0061] In the same sliding sleeve 403, the lower part of the sliding sleeve 403 is connected to the turnbuckle 601 of one of the tensioning structures, and the upper part of the sliding sleeve 403 is connected to the steel rope 604 of another tensioning structure.

[0062] In this embodiment, the turnbuckle 601 and the U-shaped clamp used to fix the steel rope 604 are existing technologies and will not be described in detail.

[0063] During use, the staff manually adjusts each turnbuckle 601 to make all steel ropes 604 taut. After all steel ropes 604 are taut, they simultaneously pull the four sliding sleeves 403 in the vertical direction, so that the sliding sleeves 403 are balanced under force. As a result, when the two hydraulic cylinders I11 drive the lifting frame 4 to move up and down, the lifting frame 4 can move smoothly and stably without jamming.

[0064] In some embodiments of this application, the hoisting frame 5 includes a frame body 501, the lower end of the frame body 501 is fixed with a plurality of hooks 502 for hoisting the filter screen 13, and the upper end of the frame body 501 is suspended on the horizontal column I 401 and can move along the horizontal column I 401.

[0065] The frame 501 is connected to hydraulic cylinders II12 that are distributed along the horizontal column I401 and fixed to the upper end of the horizontal column I401.

[0066] In this embodiment, a lifting lug 14 is fixed at the upper middle position of the filter screen 13. The lifting lug 14 has a through hole 15. The filter screen 13 can be hung on the lifting hook 502 by passing the hook 502 through the through hole 15.

[0067] In this embodiment, hydraulic cylinder II12 is connected to a hydraulic station, and the hydraulic station controls the extension and retraction of hydraulic cylinder II12.

[0068] In use, the operator operates the hydraulic station. After the hydraulic station controls the hydraulic cylinder II 12 to extend, the lifting frame 5 moves to the right, that is, to the side of the ultrasonic cleaning tank 1. After the hydraulic station controls the hydraulic cylinder II 12 to shorten, the lifting frame 5 moves to the left, that is, to the top of the ultrasonic cleaning tank 1.

[0069] In some embodiments of this application, the horizontal column I401 has an I-shaped structure;

[0070] The upper end of the frame 501 is detachably fixed with multiple equidistantly distributed mounting seats 503, and the mounting seats 503 are provided with two symmetrically distributed guide wheel assemblies 504. Specifically, the mounting seat 503 includes two symmetrically distributed mounting plates, and each mounting plate is equipped with a guide wheel assembly 504. The guide wheel assembly 504 consists of two guide wheels distributed along the moving direction of the lifting frame 5. The guide wheels are rotatably connected to the mounting shaft through bearings. The mounting shaft is fixedly connected to the mounting plate, and the horizontal column I 401 is located between the two mounting plates.

[0071] The vertical section of the horizontal column I 401 is located between the two guide wheel groups 504, and the guide wheel group 504 is in contact with the upper end of the lower horizontal section of the horizontal column I 401, so that the hoisting frame 5 can move smoothly along the horizontal column I 401.

[0072] One of the mounting bases 503 is fixed with a connecting bracket 505, which is connected to the hydraulic cylinder II12.

[0073] Specifically, the mounting base 503 located on the far right of the frame 501 is fixedly connected to the connecting frame 505, and the connecting frame 505 is sleeved on the horizontal column I 401. The free end of the hydraulic cylinder II 12 is hinged to the connecting frame 505 via a pin.

[0074] In this embodiment, two mounting tubes 506 are provided between the two mounting plates. The two mounting plates and the mounting tubes 506 are fixedly connected by bolts 507. The bolts 507 pass through one of the mounting plates, the mounting tubes 506 and the other mounting plate in sequence and are engaged with nuts. The mounting tubes 506 are fixed to the upper end of the frame 501, thereby realizing the detachable connection between the mounting base 503 and the frame 501, which facilitates the hanging frame 5 on the horizontal column I 401.

[0075] In some embodiments of this application, the heating device 2 is a boiler, the water inlet of the boiler is connected to the water outlet of the ultrasonic cleaning tank 1 through a water inlet pipe 9, and a water pump and valve are installed on the water inlet pipe 9.

[0076] The boiler outlet is connected to the ultrasonic cleaning tank 1 inlet via an outlet pipe 10.

[0077] In this embodiment, the water inlet of the ultrasonic cleaning tank 1 is located at the lower part of the ultrasonic cleaning tank 1, the water inlet of the ultrasonic cleaning tank 1 is located at the upper part of the ultrasonic cleaning tank 1, the water inlet of the boiler is located at the lower part of the boiler, the water outlet of the boiler is located at the upper part of the boiler, and the water outlet pipe 10 is horizontally distributed, so that the water in the boiler can automatically flow into the ultrasonic cleaning tank 1.

[0078] In this embodiment, the boiler is existing technology and will not be described in detail.

[0079] When in use, after the ultrasonic cleaning tank 1 is filled with water, open the valve on the inlet pipe 9 and start the water pump. The water pump will pump the water in the ultrasonic cleaning tank 1 to the boiler for heating. The hot water in the boiler will flow into the ultrasonic cleaning tank 1 from the outlet pipe 10, so that the water circulates between the ultrasonic cleaning tank 1 and the boiler. During the circulation, the boiler heats the water. When the water in the ultrasonic cleaning tank 1 boils, close the valve on the inlet pipe 9 and turn off the water pump. At this time, the filter screen 13 can be moved into the ultrasonic cleaning tank 1 for cleaning.

[0080] In some embodiments of this application, the ultrasonic cleaning tank 1 includes a tank body 101 with an opening at the top. Multiple ultrasonic generators (not shown in the figure) are installed inside the tank body 101, thereby enabling the ultrasonic cleaning tank 1 to perform ultrasonic cleaning on the filter screen 13.

[0081] In this embodiment, the ultrasonic generator is existing technology and will not be described in detail.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
