[0001] This utility model relates to the field of catering technology, and more specifically, to a device for recycling grease from catering wastewater. Background Technology

[0002] The catering industry, also known as the food service industry, is a food production and operation industry that integrates on-the-spot processing, commercial sales and service labor to provide consumers with various beverages and food, as well as consumption venues and facilities. In the catering industry, a lot of wastewater and grease are generated. In order to avoid waste of wastewater and grease, catering wastewater and grease recycling devices are needed to recycle and reuse wastewater and grease.

[0003] However, in actual use, there are many impurities in the wastewater grease, such as food scraps and paper towels. The catering wastewater grease recycling device needs to use a filter screen to filter the impurities in the wastewater grease. However, the traditional catering wastewater grease recycling device has a poor cleaning effect on the filter screen and cannot perform regular and quick self-cleaning. Moreover, the self-cleaning process usually requires stopping the machine, which is very troublesome and reduces the working efficiency of the device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a catering wastewater grease recycling device to solve the problems of poor cleaning effect of filter screen in the prior art, inability to perform regular and rapid self-cleaning, and the need to stop the machine for self-cleaning, which is very troublesome and reduces the working efficiency of the device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a catering wastewater grease recycling device, including a recycling box, a partition fixed at the center of the inner cavity of the recycling box, a rotating shaft longitudinally rotatably mounted on the bottom of both sides of the inner cavity of the recycling box, a filter screen fixed on the rotating shaft, a guide seat slidably mounted on the top of both sides of the partition, the bottom of which is attached to the top of the filter screen, a feeding frame for use with the filter screen embedded on both sides of the top of the recycling box, a guide plate for use with the filter screen fixed on the bottom of both sides of the inner cavity of the recycling box, a discharge box for use with the guide plate connected to the bottom of both sides of the recycling box, and a self-cleaning component for use with the filter screen on the recycling box.

[0006] The self-cleaning component includes a reinforcing frame fixed to one end of a rotating shaft. A small cylinder is installed at the bottom of the front of the recycling bin. A conversion structure for use with the small cylinder is installed on the front of the recycling bin. The piston rod of the small cylinder is fixed to a drive frame for use with the reinforcing frame. One end of the drive frame is inserted into one of the reinforcing frames. Impact seats for use with the filter screen are inserted on the top of both sides of the recycling bin. Multiple sets of buffer springs are fixed on the protruding end of the impact seat away from the recycling bin. One end of the buffer spring is fixed to the side of the recycling bin. Multiple sets of impact tubes for use with the filter screen are connected sequentially along the front-back direction on both sides of the top of the recycling bin. The top ends of adjacent sets of impact tubes are connected to a connecting frame for connecting to an external water pipe.

[0007] The conversion structure includes an L-shaped fixing plate fixed to the bottom front of the recycling bin. The L-shaped fixing plate has symmetrical fixing grooves on the left and right sides. A movable frame is slidably arranged in the fixing groove. The bottom of the movable frame is rotatably equipped with an installation block and a small cylinder is fixed in the installation block. The top of the movable frame is fixed to a protrusion. An auxiliary spring is fixed on the side of the protrusion and the bent end of the L-shaped fixing plate that are close to each other. An L-shaped anti-shift plate is snapped into each of the fixing grooves and the back of the L-shaped anti-shift plate is attached to the movable frame.

[0008] The recycling bin has buffer frames inserted on both sides of its top. The bottom of the buffer frame is fixed to the flow guide seat.

The pre-positioning bolt on the right is inserted into the corresponding positioning sleeve, and there is a gap between the pre-positioning bolt on the left and the corresponding positioning sleeve.

[0010] The drive frame has an overall T-shaped structure, and the end of the drive frame away from the small cylinder has a cylindrical structure.

[0011] The guide plate has a guide strip fixed to the right side of its top, which is attached to the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above solution, by setting up a self-cleaning component, the filter screen can reciprocate and impact the guide seat while filtering impurities in the wastewater grease, causing the filter screen to vibrate continuously, thus preventing excessive adhesion of impurities. The angle of the filter screen can also be significantly changed, swinging the side with attached impurities to contact the impact seat and continuously impacting it, causing the filter screen to vibrate continuously. This quickly shakes off the impurities on the filter screen and makes them fall onto the guide plate. Furthermore, with the cooperation of the connecting frame and the impact tube, the purified water filter screen can be used for impact, further cleaning the filter screen. At this point, using multiple and varied self-cleaning methods, the impurities attached to the filter screen can be quickly removed. The design of the conversion structure allows the filtration of two sets of filter screens to use the same drive structure, saving costs. Both filtration systems can continuously filter wastewater grease, and the entire cleaning process can be completed without stopping the machine to replace the filter screen, greatly improving the filtration efficiency of the device for impurities in wastewater grease.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1: Please refer to Figures 1 to 5This utility model provides a technical solution: a device for recycling grease from catering wastewater, including a recycling box 1. A controller is installed on the top of the back of the recycling box 1. A partition 2 is fixed at the center of the inner cavity of the recycling box 1. Rotating shafts 7 are longitudinally rotatably mounted on the bottom of both sides of the inner cavity of the recycling box 1. Filter screens 6 are fixed on the rotating shafts 7. Guide seats 8 with their bottoms attached to the top of the filter screens 6 are slidably installed on the top of both sides of the partition 2. Feeding frames 4 that cooperate with the filter screens 6 are embedded on both sides of the top of the recycling box 1. Guide plates 5 that cooperate with the filter screens 6 are fixed on the bottom of both sides of the inner cavity of the recycling box 1. A guide strip 11 is fixed to the right side and fits onto the rotating shaft 7. The design of the guide strip 11 prevents impurities from accumulating at the contact point between the rotating shaft 7 and the guide plate 5, thus affecting the normal swing of the rotating shaft 7. The bottom of both sides of the recycling box 1 is connected to a discharge box 3 that works with the guide plate 5. The recycling box 1 is equipped with a self-cleaning component that works with the filter screen 6. The self-cleaning component includes a reinforcing frame 12 fixed to one end of the rotating shaft 7. A small cylinder 19 is installed at the bottom of the front of the recycling box 1. The piston rod of the small cylinder 19 is fixed to a drive frame 21 that works with the reinforcing frame 12. One end of the drive frame 21 is inserted into one of the sets of reinforcing frames. Inside frame 12, drive frame 21 has a T-shaped structure. The end of drive frame 21 away from small cylinder 19 has a cylindrical structure so that drive frame 21 can be stably connected to reinforced frame 12 and can drive reinforced frame 12 to swing back and forth stably without obstruction. Impact seats 24 for use with filter screen 6 are inserted on the top of both sides of recycling box 1. Multiple sets of buffer springs 25 are fixed on the protruding end of impact seat 24 away from recycling box 1. One end of buffer spring 25 is fixed to the side of recycling box 1. Multiple sets of impact seats for use with filter screen 6 are connected sequentially on both sides of the top of recycling box 1 along the front and back direction. The top of each of the multiple sets of impact pipes 22 is connected to a connecting frame 23 for docking with an external water pipe. Buffer frames 9 are inserted on both sides of the top of the recovery box 1. The bottom of the buffer frame 9 is fixed to the flow guide seat 8. A return spring 10 is wound around the column of each set of buffer frames 9. The two ends of the return spring 10 are fixed to the top protrusion of the buffer frame 9 and the recovery box 1. By utilizing the elastic rebound of the return spring 10, a certain pulling force can be continuously applied to the buffer frame 9 and the flow guide seat 8 so that the flow guide seat 8 can be reset in time when subjected to force, which facilitates the reciprocating impact on the filter screen 6 and improves the shaking effect on the impurities on the filter screen 6.

[0023] By setting a self-cleaning component, when the filter screen 6 filters impurities in the grease of sewage, it reciprocates with the guide seat 8, causing the filter screen 6 to vibrate continuously, thus preventing excessive adhesion of impurities. The angle of the filter screen 6 can also be changed significantly, swinging the side with impurities attached to it to contact the impact seat 24 and continuously impacting the impact seat 24, so that the filter screen 6 can continuously generate vibration. This can quickly shake off the impurities on the filter screen 6 and make them fall onto the guide plate 5. With the cooperation of the connecting frame 23 and the impact tube 22, the water purification filter screen 6 can be impacted, thereby further cleaning the filter screen 6. At this time, by using multiple and various forms of self-cleaning methods, the impurities attached to the filter screen 6 can be quickly removed.

[0024] Example 2: Based on Example 1, in order to adaptively drive the two sets of filter screens 6 and make the self-cleaning of the two sets of filter screens 6 use the same drive structure to save costs, a conversion structure needs to be set on the small cylinder 19. This allows the other set of filter screens 6 to be continuously driven to swing and continuously impact the guide seat 8 after one set of filter screens 6 has finished cleaning, thus avoiding excessive adhesion of impurities. The front of the recycling box 1 is provided with a conversion structure that works in conjunction with the small cylinder 19. The conversion structure includes an L-shaped fixing plate 13 fixed to the bottom of the front of the recycling box 1. The L-shaped fixing plate 13 has symmetrical fixing grooves 15 on the left and right sides. A movable frame 14 is slidably arranged in the fixing grooves 15. The bottom of the movable frame 14 is rotatably equipped with a mounting block 17 and the small cylinder 19 is also rotatably mounted on it. The cylinder 19 is fixed inside the mounting block 17. The top of the moving frame 14 is fixed to the protrusion, and an auxiliary spring 16 is fixed on the side of the protrusion and the bent end of the L-shaped fixing plate 13 that are close to each other. Each set of fixing slots 15 is fitted with an L-shaped anti-slip plate 18, and the back of the L-shaped anti-slip plate 18 is attached to the moving frame 14. The top of each set of reinforcing frames 12 is threaded with a pre-positioning bolt 20 through a screw hole. The recycling box 1 is fixed with a positioning sleeve that works with the pre-positioning bolt 20. The right pre-positioning bolt 20 is inserted into the corresponding positioning sleeve, and there is a gap between the left pre-positioning bolt 20 and the corresponding positioning sleeve. The design of the pre-positioning bolt 20 and the positioning sleeve is so that the reinforcing frame 12 can be pre-positioned during conversion, so that the drive frame 21 can be stably inserted into the reinforcing frame 12.

[0025] The design of the conversion structure allows for rapid adjustment of the angle of the small cylinder 19, which in turn allows for synchronous adjustment of the position of the drive frame 21. When one set of filter screens 6 becomes clogged, after cleaning that set of filter screens 6, the position of the drive frame 21 can be quickly switched and connected to another set of reinforcing frames 12. This allows the other set of filter screens 6 to continue swinging and continuously impacting the guide seat 8, preventing excessive adhesion of impurities. The other set of filter screens 6 can be continuously cleaned subsequently. The self-cleaning of both sets of filter screens 6 uses the same drive structure, which saves costs and ensures continuous filtration of impurities in wastewater and grease.

[0026] The working process of this utility model is as follows:

[0027] The user pours wastewater grease through one set of discharge frames 4 onto the corresponding filter screen 6. Simultaneously, the user activates the small cylinder 19 via the controller and presets its reciprocating stroke, which drives the drive frame 21 to move back and forth. This, in turn, drives the reinforcing frame 12 to swing back and forth. The elastic rebound of the return spring 10 assists in the reset of the buffer frame 9, allowing the corresponding filter screen 6 to continuously impact the guide seat 8 with a small amplitude, shaking off the impurities attached to it and preventing excessive accumulation of impurities. If there is a large amount of impurities clogging the mesh of the filter screen 6, the user pours the wastewater grease through another set of discharge frames 4, and drives the drive frame 21 via the small cylinder 19. The frame 21 moves a longer distance, thereby expanding the swing angle of the reinforcing frame 12 until the side of the filter screen 6 with impurities attached swings to contact the impact seat 24. At this point, the entire filter screen 6 swings to a right-tilted position. The reciprocating stroke of the small cylinder 19 is then reset, driving the filter screen 6 to swing rapidly with a small amplitude. The elastic rebound of the buffer spring 25 drives the impact seat 24 to quickly return to its original position, thus reciprocatingly impacting the impact seat 24. This causes the filter screen 6 to continuously vibrate, quickly shaking off the impurities on the filter screen 6. Due to the change in tilt, the impurities are directly shaken off without slowly passing through the filter screen 6 again. As the filter falls, impurities will fall directly and quickly onto the guide plate 5. The user then connects the external water pipe to the connecting frame 23 and rapidly delivers clean water to the impact pipe 22. The water then impacts multiple points on the filter screen 6, further cleaning it. After cleaning, the user resets the filter screen 6 and inserts the pre-positioning bolts 20 corresponding to the filter screen 6 into the positioning sleeve, positioning the corresponding reinforcing frame 12. The user then removes the L-shaped anti-shift plate 18 from the fixing groove 15, releasing the locking state of the moving frame 14. Pulling the moving frame 14 forward then drives the mounting block 17. Move forward until one end of the drive frame 21 disengages from the reinforcing frame 12. At this point, the user rotates the mounting block 17 until it rotates 180 degrees. The elastic rebound of the auxiliary spring 16 will reset the mounting block 17, and the other end of the drive frame 21 will be inserted into another set of reinforcing frames 12. Then, the user reinserts the L-shaped anti-shift plate 18 into the fixing slot 15 to limit the mounting block 17. At this point, the user rotates the pre-positioning bolt 20 on the other set of reinforcing frames 12 to disengage it from the corresponding positioning sleeve. This will drive the other set of filter screens 6 to swing slightly and reciprocate against the guide seat 8, thereby continuously filtering sewage grease.
