Description

Technical Field

[0001] This invention relates to the field of food cleaning equipment technology, and in particular to a cleaning equipment for pre-processed food. Background Technology

[0002] Cleaning equipment for pre-made pet food is a specialized device used in the production of pet food to clean food raw materials (such as meat, grains, vegetables, etc.). Its core function is to remove stains, impurities, pesticide residues, or microorganisms from the surface of raw materials through a series of structural designs, providing clean raw materials for subsequent pet food processing (such as crushing, mixing, pelleting, etc.) and ensuring the safety and hygiene of pet food.

[0003] For example, application number CN202122826657.1 discloses a water-saving cleaning device for pet food processing, including a cleaning tank. A cleaning bucket is mounted on top of the cleaning tank, and a processing tank is fixedly connected to the outer wall of one end of the cleaning tank. A water pump is fixedly connected to one side of the top of the processing tank. A water pump pipe is fixedly connected to the top of the water pump and inserted into the cleaning tank, while a drain pipe is fixedly connected to the bottom of the water pump and inserted into the processing tank. A return pipe is fixedly connected to the bottom of the processing tank and inserted into the processing tank, with a one-way valve on one side of the return pipe. A filter screen is fixedly connected between the side wall and the bottom inner wall of the cleaning tank. This utility model facilitates the cleaning of pet food raw materials. The pet food raw materials in the cleaning bucket are propelled out by an auger, making operation convenient. The water is recycled back into the cleaning tank through the return pipe, effectively saving water.

[0004] For example, application number CN202322013549.1 discloses a raw material cleaning device for meat and pet food processing, relating to the field of meat and pet food processing technology. It includes a meat and pet food raw material cleaning tank, with a filtration and discharge mechanism located below the tank. The filtration and discharge mechanism includes a discharge trough, with a filter plate slidably connected to the inner wall of the discharge trough. A discharge port is opened on the right side of the discharge trough. Below the filtration and discharge mechanism is a striking mechanism, including a motor body and a striking plate. Four evenly distributed support columns are fixedly connected to the bottom of the discharge trough. By using the cooperation between the filtration and discharge mechanism and the striking mechanism, it can not only accelerate the separation of meat and pet food raw materials from water, but also concentrate and transport the separated meat and pet food to the outside of the device, thereby facilitating the collection of the cleaned meat and pet food and improving the efficiency of meat and pet food cleaning.

[0005] Food cleaning devices similar to those described above also have the following shortcomings: It is inconvenient to turn food raw materials in multiple directions during cleaning, resulting in poor cleaning effect; it is not possible to perform double cleaning inside and outside, resulting in low cleaning efficiency; after cleaning, a separate dehydration device or dehydration structure is required for dehydration, which is costly. Summary of the Invention

[0006] This invention relates to a cleaning device for pre-processed food, which solves the problems of inconvenience in multi-directional turning of food raw materials during cleaning, resulting in poor cleaning effect; inability to perform double cleaning inside and outside during cleaning, resulting in low cleaning efficiency; and the need for separate dehydration equipment or dehydration structure after cleaning, which leads to high costs.

[0007] This invention provides a cleaning device for pre-processed food, specifically comprising: a liquid storage tank; a first mounting arm fixed to the liquid storage tank by a screw, a second mounting arm rotatably mounted on the first mounting arm, a worm gear welded to the first mounting arm, a worm rotating on the second mounting arm, the worm meshing with the worm gear, a first motor fixed to the second mounting arm, and the output shaft of the first motor fixed to the worm.

[0008] Furthermore, two first hydraulic cylinders are symmetrically fixed to the bottom end of the second mounting arm. Each first hydraulic cylinder has a mounting seat fixed to its extended end. A drive rod is welded to the upper end of each mounting seat. The first mounting arm, the second mounting arm, the worm gear, the worm, the first motor, the first hydraulic cylinder, the mounting seat, and the drive rod together form the adjustment part. The drive rod is a cylindrical rod structure. The upper end of the drive rod is polished, and after polishing, the upper end of the drive rod is an arc-shaped structure.

[0009] Furthermore, a receiving part is installed on the first hydraulic cylinder. The receiving part consists of a base, a rotating shaft, a cleaning cylinder, a through hole, a retaining ring, a coil spring, gear A, a second motor, and gear B. Each first hydraulic cylinder has a fixed base, and a rotating shaft rotates on the two bases. A cleaning cylinder is welded on the rotating shaft, and through holes are opened at equal intervals on the cleaning cylinder.

[0010] Furthermore, gear A is welded onto the rotating shaft, a second motor is fixed on a base on the right side, and gear B is fixed on the output shaft of the second motor, with gear B meshing with gear A.

[0011] Furthermore, a retaining ring is welded to the extended end of each of the first hydraulic cylinders, and a helical spring is sleeved on the extended end of each of the first hydraulic cylinders. The upper end of the helical spring contacts the retaining ring, and the lower end of the helical spring contacts the seat. The drive rod is engaged with the through hole. When the cleaning cylinder rotates, the cleaning cylinder vibrates continuously under the action of the drive rod.

[0012] Furthermore, the rotating shaft is a hollow structure with spray holes evenly spaced on it. A cleaning unit is installed on the rotating shaft, which consists of a first liquid supply pipe, an air supply pipe, a spray pipe, a second liquid supply pipe, and a water pump. The first liquid supply pipe is connected to the rotating shaft through a rotating joint, and the other end of the first liquid supply pipe is connected to the water pump, which is fixed inside the liquid storage tank.

[0013] Furthermore, nozzles are fixed on both of the seats, and a second liquid supply pipe is connected to the nozzles. The second liquid supply pipe is also connected to a water pump.

[0014] Furthermore, an air supply pipe is connected to the first liquid supply pipe, and the air supply pipe is connected to an external air pump. Both the first liquid supply pipe and the air supply pipe are equipped with electric valves.

[0015] Furthermore, a collection section is installed on the liquid storage tank. The collection section consists of a second hydraulic cylinder and a storage box. Two second hydraulic cylinders are symmetrically fixed to the rear end of the liquid storage tank. The extended ends of the two second hydraulic cylinders are fixed to the storage box, and the storage box slides on the liquid storage tank.

[0016] This invention provides a cleaning device for pre-processed food, which has the following beneficial effects: In this application, the design of the adjustment unit is particularly crucial in the cleaning process. A primary motor drives a worm gear to mesh with a worm wheel, allowing for flexible adjustment of the cleaning cylinder's tilt angle. This, combined with the first hydraulic cylinder on the second mounting arm, lifts and lowers the cleaning cylinder, ensuring thorough agitation of the raw materials in the cleaning solution and enabling cleaning above the liquid surface. Simultaneously, the cleaning cylinder itself rotates via gear transmission driven by a secondary motor, further enhancing the mixing effect of the raw materials and preventing uneven cleaning caused by localized accumulation. The drive rod is ground into an arc shape, effectively reducing wear when in contact with the through-hole of the cleaning cylinder, thus lowering equipment maintenance frequency and costs, and extending service life.

[0017] This application, through the setting of the cleaning section, uses a water pump to spray the cleaning liquid in the storage tank directly onto the raw material in the cylinder through the rotating shaft nozzle. At the same time, it rinses again from the outside through the through hole via the spray pipe. The combination of internal and external cleaning ensures that the stains are thoroughly removed. Compared with existing devices, this device has a better cleaning effect.

[0018] In the dehydration process of this application, after the washing cylinder is removed from the water surface, it rotates under the drive of the motor. The cooperation between the drive rod and the through hole causes the washing cylinder to vibrate continuously, accelerating the removal of water. In addition, the air supply pipe is connected to the air pump, and the sprayed airflow blows the raw materials. The dual effect significantly improves the dehydration efficiency. No additional dehydration equipment is required, saving equipment investment and space occupation. Moreover, when dehydrating with gas, there is no need to set up a separate air jet pipe for dehydration, making the structure more optimized.

[0019] The unloading and collection process of this application is equally efficient. The second hydraulic cylinder of the collection unit can precisely drive the storage box to move under the washing cylinder. The raw material collection can be completed by opening the cylinder door, avoiding spillage and waste during manual unloading and reducing operation steps. Attached Figure Description

[0027] Example 1: Please refer to Figures 1 to 8 : This invention proposes a cleaning device for pre-processed food, comprising: a storage tank 1; a first mounting arm 201 fixed to the storage tank 1 by a screw, a second mounting arm 202 rotatably mounted on the first mounting arm 201, a worm gear 203 welded to the first mounting arm 201, and a worm 204 rotatably mounted on the second mounting arm 202, the worm 204 meshing with the worm gear 203; a first motor 205 fixed to the second mounting arm 202, the output shaft of the first motor 205 fixed to the worm 204; when the food raw materials in the cleaning cylinder 303 are turned over, the first motor 205 is driven to rotate, which in turn drives the worm 204 to rotate. Under the meshing transmission of the worm 204 and the worm gear 203, the cleaning cylinder 303 can be tilted, thus turning over the food raw materials. By turning over the food raw materials, the cleaning quality can be improved.

[0028] Two first hydraulic cylinders 206 are symmetrically fixed to the bottom end of the second mounting arm 202. Each first hydraulic cylinder 206 has a mounting seat 207 fixed to its extended end. A drive rod 208 is welded to the upper end of each mounting seat 207. The first mounting arm 201, the second mounting arm 202, the worm gear 203, the worm 204, the first motor 205, the first hydraulic cylinder 206, the mounting seat 207, and the drive rod 208 together form the adjustment part 2. The drive rod 208 is a cylindrical rod structure. The upper end of the drive rod 208 is polished. After polishing, the upper end of the drive rod 208 is an arc-shaped structure. Under the action of the arc part on the drive rod 208, the wear of the cleaning cylinder 303 and the drive rod 208 itself can be reduced, thus reducing the subsequent maintenance cost.

[0029] The first hydraulic cylinder 206 is equipped with a storage part 3, which consists of a base 301, a rotating shaft 302, a cleaning cylinder 303, a through hole 304, a retaining ring 305, a coil spring 306, a gear A 307, a second motor 308, and a gear B 309. Each first hydraulic cylinder 206 is fixed with a base 301, and a rotating shaft 302 rotates on the two bases 301. A cleaning cylinder 303 is welded to the rotating shaft 302, and through holes 304 are opened at equal intervals on the cleaning cylinder 303.

[0030] Among them, a gear A307 is welded on the rotating shaft 302, and a second motor 308 is fixed on a seat 301 on the right side. A gear B309 is fixed on the output shaft of the second motor 308. Gear B309 meshes with gear A307. When cleaning food raw materials, the food raw materials are added into the cleaning cylinder 303, which drives the two first hydraulic cylinders 206 to extend. The two first hydraulic cylinders 206 drive the cleaning cylinder 303 to move downward until the cleaning cylinder 303 is immersed in the liquid inside the storage tank 1. This drives the second motor 308 to rotate. Through the meshing transmission of gear B309 and gear A307, the rotation of the cleaning cylinder 303 can be realized. When the cleaning cylinder 303 rotates, the food raw materials inside can be turned over and cleaned, resulting in a good cleaning effect.

[0031] Each first hydraulic cylinder 206 has a retaining ring 305 welded to its extended end, and a helical spring 306 sleeved on its extended end. The upper end of the helical spring 306 contacts the retaining ring 305, and the lower end of the helical spring 306 contacts the seat 301. The drive rod 208 is engaged with the through hole 304. When the washing cylinder 303 rotates, it vibrates continuously under the action of the drive rod 208. When dehydration is required after washing, the two first hydraulic cylinders 206 are driven to retract until the washing cylinder 303 is removed from the water surface, driving the second motor 308 to rotate. Through the meshing transmission of gear B309 and gear A307, the washing cylinder 303 can be rotated. During the rotation of the washing cylinder 303, it vibrates continuously under the action of the drive rod 208 and the through hole 304, thereby realizing the vibration dehydration of food raw materials without the need for separate dehydration equipment, saving costs.

[0032] The rotating shaft 302 is a hollow structure with spray holes evenly spaced on it. A cleaning unit 4 is installed on the rotating shaft 302. The cleaning unit 4 consists of a first liquid supply pipe 401, an air supply pipe 402, a spray pipe 403, a second liquid supply pipe 404, and a water pump 405. The first liquid supply pipe 401 is connected to the rotating shaft 302 via a rotating joint. The other end of the first liquid supply pipe 401 is connected to the water pump 405, which is fixed inside the liquid storage tank 1. When cleaning the food raw materials inside the cleaning cylinder 303, the water pump 405 is started, and the water pump 405 delivers the cleaning liquid to the rotating shaft 302. The liquid is sprayed out through the spray holes of the rotating shaft 302 to clean the food raw materials inside the cleaning cylinder 303.

[0033] The two bases 301 are fixed with spray pipes 403, and the spray pipes 403 are connected to a second liquid supply pipe 404. The second liquid supply pipe 404 is also connected to a water pump 405. During cleaning, the water pump 405 delivers the cleaning liquid to the spray pipes 403 through the second liquid supply pipe 404. The liquid sprayed from the spray pipes 403 passes through the through hole 304 and can clean the food raw materials inside the cleaning cylinder 303 again, resulting in a good cleaning effect.

[0034] The liquid storage tank 1 is equipped with a collection section 5, which consists of a second hydraulic cylinder 501 and a collection box 502. Two second hydraulic cylinders 501 are symmetrically fixed to the rear end of the liquid storage tank 1. The extended ends of the two second hydraulic cylinders 501 are fixed to the collection box 502. The collection box 502 slides on the liquid storage tank 1. When the food raw materials are unloaded after cleaning, the two second hydraulic cylinders 501 are driven to retract. The two second hydraulic cylinders 501 drive the collection box 502 to move into the liquid storage tank 1. When the collection box 502 moves into the cleaning cylinder 303, the door panel on the cleaning cylinder 303 is opened. At this time, the food raw materials inside the cleaning cylinder 303 will fall into the collection box 502 for collection.

[0035] Example 2, based on Example 1, such as Figures 1-8 As shown, a gas supply pipe 402 is connected to the first liquid supply pipe 401. The gas supply pipe 402 is connected to an external air pump. Both the first liquid supply pipe 401 and the gas supply pipe 402 are equipped with electric valves. When dehydrating the food raw materials inside the washing cylinder 303, the washing cylinder 303 is first removed from the liquid surface, and then the external air pump is started. At this time, the gas is sprayed out through the nozzle on the rotating shaft 302. The airflow sprayed out from the nozzle can play an auxiliary role in dehydrating the food raw materials and improve the dehydration effect of the food raw materials.

[0036] The working principle of this embodiment is as follows: When using the pre-processed food cleaning equipment, the food raw materials to be cleaned are first added into the cleaning cylinder 303; then, the two first hydraulic cylinders 206 are driven to extend, causing the cleaning cylinder 303 to move downwards until the cleaning cylinder 303 is completely immersed in the liquid inside the storage tank 1; subsequently, the water pump 405 is started, and the water pump 405 delivers the cleaning liquid in the storage tank 1 to the hollow rotating shaft 302 through the first liquid supply pipe 401. The liquid is sprayed out through the nozzles on the rotating shaft 302. The cleaning solution is also supplied to the spray nozzle 403 through the second supply pipe 404. The liquid sprayed from the spray nozzle 403 passes through the through hole 304 on the cleaning cylinder 303 for cleaning. During this process, the drive motor 308 rotates, which drives the rotating shaft 302 to rotate through the meshing of gear B309 and gear A307, thereby causing the cleaning cylinder 303 to rotate. At the same time, because the drive rod 208 is engaged with the through hole 304, the cleaning cylinder 303 vibrates continuously during rotation. If it is necessary to further agitate the food raw materials, the drive motor can be used to further agitate the raw materials. The first motor 205 rotates, driving the worm gear 204 to rotate. Through the meshing transmission between the worm gear 204 and the worm wheel 203, the second mounting arm 202 rotates relative to the first mounting arm 201, achieving the tilting of the cleaning cylinder 303. After cleaning, the two first hydraulic cylinders 206 are driven to retract, moving the cleaning cylinder 303 upward until it is removed from the liquid surface in the storage tank 1. Then, the second motor 308 is driven to rotate, keeping the cleaning cylinder 303 rotating and the drive rod 208 and the through hole 3... Under the action of 04, continuous vibration occurs, and the electric valve on the air supply pipe 402 is opened, starting the external air pump. Gas enters the rotating shaft 302 through the air supply pipe 402 and the first liquid supply pipe 401, and is ejected from the nozzle of the rotating shaft 302. After dehydration, the two second hydraulic cylinders 501 are driven to retract, causing the storage box 502 to slide into the liquid storage tank 1 until the storage box 502 moves to the bottom of the washing cylinder 303. Finally, the door panel on the washing cylinder 303 is opened, allowing the food raw materials inside to fall into the storage box 502.

[0037] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
