Description

Technical Field

[0001] This invention belongs to the field of blade cleaning technology, specifically relating to a refrigeration device that facilitates blade cleaning. Background Technology

[0002] Existing industrial refrigeration equipment mainly consists of compressors, expansion valves, evaporators, condensers, accessories, and pipelines. According to their working principles, they can be divided into compression refrigeration equipment, absorption refrigeration equipment, steam jet refrigeration equipment, heat pump refrigeration equipment, and electric heating refrigeration devices. Some production equipment in factories generates a lot of heat during industrial production, which can affect the performance and lifespan of the equipment. In order to reduce the heat of the production equipment and enable it to work normally, industrial refrigeration equipment is generally used to cool the production equipment.

[0003] When industrial refrigeration equipment is in use, the blades generate static electricity during rotation. Under the influence of static electricity, dust around the blades is attracted to the blades. Over time, excessive dust accumulation on the blades will negatively affect the operation of the equipment. Most existing blade cleaning methods require disassembling the blades for cleaning. Since the blades have protective mesh covers on the outside and are fixed to the motor shaft, multiple parts need to be disassembled before cleaning and reassembled after cleaning. This operation is cumbersome, inefficient, and not conducive to cleaning blades on large-scale refrigeration equipment.

[0004] Therefore, a refrigeration device that facilitates the cleaning of blades is proposed. Summary of the Invention

[0005] The present invention provides a refrigeration device that facilitates the cleaning of blades, and its purpose is to solve the problems mentioned above.

[0006] This invention provides a refrigeration device for easy blade cleaning, including a refrigeration unit. Two movable slots are symmetrically formed on one outer wall of the refrigeration unit, and a panel is provided on one outer wall of the refrigeration unit near the two movable slots. Installation slots are formed on the inner side walls of the two movable slots near the outer wall of the refrigeration unit. A gear cavity is formed inside the refrigeration unit near the lower part of the movable slots, and a through hole is formed inside the refrigeration unit near the position between the movable slots and the gear cavity. Both the movable slots and the gear cavity are connected to the through hole. A pull-out slot is formed on the horizontal side of the refrigeration unit near the gear cavity. A stop is provided on the inner wall of the pull-out slot near the outer side. A blade deflection assembly is provided inside the movable slot. A disassembly plate is fixedly connected to one outer wall of the refrigeration unit near the outer side of the movable slot by screws. A filter screen is provided on the outer wall of the disassembly plate away from the refrigeration unit. The blade steering assembly includes a support cover embedded and fixed inside a movable slot. Two mounting plates are symmetrically arranged on the outer wall of the support cover. The mounting plates are embedded in the mounting slot and fixed to the mounting slot by screws. An upper rotating column is provided on the top of the support cover, and through holes are provided on the top and bottom of the support cover. The upper rotating column and the lower rotating column respectively movably pass through the two through holes. A circular sleeve is provided between the upper rotating column and the lower rotating column. The lower rotating column movably passes through the through hole, and a gear is provided at the bottom end of the lower rotating column near the gear cavity. A pull-out toothed plate movably slides inside the pull-out slot. A limit block is provided on one side of the outer wall of the pull-out toothed plate near one end, and a connecting plate is provided on the other side of the pull-out toothed plate. The connecting plate is fixed to the refrigeration unit, and the pull-out toothed plate and the gear are connected by gear meshing.

[0007] Furthermore, the inner wall of the support cover is provided with an arc surface that allows the circular sleeve to rotate horizontally. The outer circumferential surface of the circular sleeve is provided with a first mating surface and a second mating surface that dynamically seal with the arc surface. The first mating surface is located on one side of the second mating surface. Two motor brackets are symmetrically arranged on the inner circumferential surface of the circular sleeve. A servo motor is fixedly connected between the two motor brackets by bolts. An impeller is fixedly connected to the servo motor through its output end on one side. Several blades are arranged at equal intervals in the circumferential direction on the outer circumferential surface of the impeller.

[0008] Furthermore, an air inlet channel is provided inside the refrigerator near the horizontal side of the movable slot. A water-blocking component is installed inside the air inlet channel. A vertical sliding groove is provided on the inner wall of the air inlet channel near the connection with the movable slot. A horizontal slot is provided on the outer wall of the refrigerator near the top of the movable slot. The horizontal slot and the vertical sliding groove are connected. The water-blocking component includes two water-blocking plates that slide symmetrically inside the vertical sliding groove. A crossbar is provided on one side of the outer wall of the two water-blocking plates near the inner position of the horizontal slot. A frustum is provided at one end of the crossbar near the outer position of the refrigerator. A slider is provided at the top and bottom of the water-blocking plates. Two elastic sleeves are symmetrically arranged on one side of the outer wall of the refrigerator near the outer position of the horizontal slot. An inclined guide plate is provided at both ends of the two elastic sleeves.

[0009] Furthermore, a drainage groove is provided at the bottom of the air inlet channel near the baffle plate, and an inclined drainage channel connected to the drainage groove is provided on one side of the outer wall of the refrigeration unit. The inclined drainage channel is composed of a vertical channel and a horizontal channel that are vertically connected, and the horizontal channel has an inclination angle of 15 degrees with the horizontal plane.

[0010] Furthermore, the circular sleeve and its internal impeller do not come into contact with the filter screen, support cover, and baffle plate during rotation; By adopting the above technical solution, the smooth rotation of the sleeve and impeller can be guaranteed. After the sleeve rotates 180 degrees, the impeller inside the sleeve can move 180 degrees in a synchronous circumferential direction, so that the reverse side of the blades on the impeller faces the outside of the refrigerator, which is convenient for cleaning the reverse side of the blades under external high pressure flushing.

[0011] Furthermore, the stop block and the limiting block are located on the same horizontal axis. When the pull-out toothed plate slides in a straight line, the limiting block on the pull-out toothed plate and the stop block will cause motion interference. By adopting the above technical solution, the limiting block on the toothed plate can move synchronously during the pulling process of the toothed plate. Under the limitation of the stop block, the toothed plate is prevented from falling out of the pulling groove, and the maximum moving distance of the toothed plate is also limited. By using the pulling distance of the toothed plate, the number of rotations of the gear can be controlled, and thus the gear can be controlled to rotate 180 degrees, which facilitates the impeller to flip direction, so as to clean the impeller from all directions.

[0012] Furthermore, the elastic sleeve is a ring-shaped structure with a notch, and the outer peripheral surface of the elastic sleeve forms a 150-degree angle with the inclined guide plate, and the inner peripheral surface of the elastic sleeve matches and fits the outer peripheral surface of the frustum. By adopting the above technical solution, with the guidance and cooperation of the two inclined guide plates, the frustum can be easily embedded in the interior of the elastic sleeve during horizontal movement. The elastic sleeve limits the position of the frustum, ensuring the stability of the baffle plate.

[0013] Furthermore, when the elastic retaining sleeve and the frustum are engaged together, the two water baffles are tightly joined together and block the air inlet channel. By adopting the above technical solution, two baffles can be used to block the air intake channel, thereby preventing water and dust mixture generated during blade cleaning from entering the interior of the refrigeration unit and avoiding pollution, corrosion and damage to the interior of the refrigeration unit.

[0014] The beneficial effects of this invention are as follows: 1. This invention, through the cooperation of the blade steering component and the water-blocking component, not only achieves precise adjustment of the blade orientation, but also discharges the wastewater generated during the cleaning process from the refrigeration unit. The blade orientation adjustment can be achieved simply by pulling the toothed plate, making the operation simple and convenient. High-pressure water flow is used to rinse the front and back of the blades, which can be achieved without disassembling the filter screen and blades. The cleaning efficiency is high, and the operation is convenient and efficient. By blocking and guiding the water flow, not only can the wastewater generated during the cleaning process be discharged, but it can also prevent the wastewater from entering the interior of the refrigeration unit and avoid damage to the internal components of the refrigeration unit.

[0015] 2. By adjusting the position of the two baffles inside the refrigeration unit, the present invention can control the opening and closing state of the air inlet channel. When the air inlet channel is closed, it can prevent water from entering the blades during the rinsing process, thus preventing water and dust mixture generated during blade cleaning from entering the interior of the refrigeration unit, avoiding contamination, corrosion and damage to the interior of the refrigeration unit, and can discharge the wastewater generated during cleaning from the refrigeration unit, ensuring the cleanliness of the blades and the overall refrigeration unit.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Reference Figure 1-5 and Figure 7-8 This invention provides a refrigeration device for easy blade cleaning, comprising a refrigeration unit 1. Two movable slots 11 are symmetrically formed on one outer wall of the refrigeration unit 1, and a panel 5 is provided on one outer wall of the refrigeration unit 1 near the two movable slots 11. Mounting slots 111 are formed on the inner side walls of the two movable slots 11 near the outer wall of the refrigeration unit 1. A gear cavity 13 is formed inside the refrigeration unit 1 near the lower part of the movable slots 11. The interior of the refrigeration unit 1 is located near the movable slots 11 and the gear cavity 13. A through hole 12 is provided at the position of the space. The movable groove 11 and the gear cavity 13 are both connected to the through hole 12. A pull-out groove 14 is provided on the horizontal side of the interior of the refrigerator 1 near the gear cavity 13. A stop block 141 is provided on the inner wall of one side of the pull-out groove 14 near the outer position. A blade deflection assembly 3 is provided inside the movable groove 11. A disassembly plate 2 is fixedly connected to the outer wall of one side of the refrigerator 1 near the outer side of the movable groove 11 by screws. A filter screen 21 is provided on the outer wall of the disassembly plate 2 away from the refrigerator 1. The blade steering assembly 3 includes a support cover 31 embedded and fixed inside the movable groove 11. Two mounting plates 311 are symmetrically arranged on the outer wall of the support cover 31. The mounting plates 311 are embedded in the mounting groove 111 and fixed to the mounting groove 111 by screws. An upper rotating column 312 is provided on the top of the support cover 31, and through holes 315 are provided at both the top and bottom of the support cover 31. The upper rotating column 312 and the lower rotating column 313 respectively movably pass through the interior of the two through holes 315. A circular sleeve 32 is provided between the components. During rotation, the circular sleeve 32 and its internal impeller 35 do not contact the filter screen 21, support cover 31, or baffle plate 41, ensuring smooth rotation of the circular sleeve 32 and impeller 35. After the circular sleeve 32 rotates 180 degrees, the impeller 35 inside the circular sleeve 32 can synchronously move 180 degrees circumferentially, thus allowing the reverse side of the blades on the impeller 35 to face the outside of the refrigerator 1, facilitating cleaning of the reverse side of the blades under external high-pressure rinsing. The lower rotating column 313 movably penetrates the through hole 12, and the lower rotating column 313... A gear 314 is located at the bottom end of the gear cavity 13 near the interior of the gear cavities 13. A pull-out toothed plate 36 slides movably inside the pull-out groove 14. A limit block 361 is located on one side of the outer wall of the pull-out toothed plate 36 near one end. The stop block 141 and the limit block 361 are located on the same horizontal axis. When the pull-out toothed plate 36 slides linearly, the limit block 361 on the pull-out toothed plate 36 interferes with the stop block 141. During the pull-out process of the pull-out toothed plate 36, the limit block 361 on the pull-out toothed plate 36 moves synchronously and... The stop block 141 limits the pull-out toothed plate 36 to prevent it from falling out of the pull-out groove 14 and also limits the maximum movement distance of the pull-out toothed plate 36. By using the pull-out distance of the pull-out toothed plate 36, the number of rotations of the gear 314 can be controlled, and the gear 314 can be controlled to rotate 180 degrees, which facilitates the flipping direction of the impeller 35 for all-round cleaning of the impeller 35. A connecting plate 362 is provided on the other side of the pull-out toothed plate 36. The connecting plate 362 is fixedly connected to the refrigerator 1. The pull-out toothed plate 36 and the gear 314 are connected by gear teeth meshing. The inner wall of the support cover 31 is provided with an arc surface 316 for the circular sleeve 32 to rotate horizontally. The outer circumferential surface of the circular sleeve 32 is provided with a first mating surface 321 and a second mating surface 322 that dynamically seal with the arc surface 316. The first mating surface 321 is located on one side of the second mating surface 322. Two motor brackets 33 are symmetrically arranged on the inner circumferential surface of the circular sleeve 32. A servo motor 34 is fixedly connected between the two motor brackets 33 by bolts. An impeller 35 is fixedly connected to the output end of the servo motor 34 on one side. Several blades are arranged at equal intervals in the circumferential direction on the outer circumferential surface of the impeller 35. To facilitate convenient and efficient blade cleaning, this embodiment utilizes the cooperation of the blade deflection assembly 3 and the water-blocking assembly 4. This not only enables precise adjustment of the blade orientation but also discharges wastewater generated during the cleaning process from the chiller 1. Blade orientation adjustment can be achieved simply by pulling the toothed plate 36, making operation simple and convenient. High-pressure water flow is used to rinse both the front and back of the blades, allowing cleaning without disassembling the filter screen 21 and the blades. This method offers high cleaning efficiency and convenient operation. Furthermore, by blocking and guiding the water flow, wastewater generated during cleaning is discharged, preventing it from entering the chiller 1 and damaging its internal components. Specifically, before cleaning the blades, the air inlet channel 19 is blocked using the water-blocking assembly 4. Then, the blades are cleaned using an external high-pressure water gun. The front of the blades is rinsed first. After rinsing one side, the connection plate 362 is disconnected from the chiller 1, and then the connection plate 362 is pulled outward from the chiller 1. Guided by the pull-out groove 14, the pull-out toothed plate 36 is stably pulled out. As the pull-out toothed plate 36 is pulled out, through the meshing transmission between the pull-out toothed plate 36 and the gear 314, the pull-out toothed plate 36 pulls the gear 314 to rotate during the movement. Under the connection of the lower rotating column 313, the gear 314 pulls the circular sleeve 32 to rotate. Under the support and rotation of the upper rotating column 312, the circular sleeve 32 rotates inside the support cover 31. With the cooperation of the arc surface 316, the first mating surface 321 and the second mating surface 322, the circular sleeve realizes... As the sleeve 32 rotates stably, the servo motor 34 and impeller 35 inside the sleeve 32 rotate synchronously. After the blades on the impeller 35 move 180 degrees in the circumferential direction, the back of the blades faces the outside of the refrigerator 1. At this time, the blades are exposed. The blades are rinsed again with an external high-pressure water gun to achieve double-sided rinsing of the blades. Finally, the pull-out toothed plate 36 is pushed into the pull-out groove 14, and the impeller 35 is reset, realizing the position adjustment of the impeller 35, which facilitates the airflow under the rotation of the impeller 35.

[0020] Example 2 Reference Figure 2 , Figure 6 , Figure 7 and Figure 9Based on the above embodiments, this embodiment of the invention further proposes that an air inlet channel 19 is provided inside the refrigerator 1 at a horizontal position near the movable slot 11. A water-blocking component 4 is provided inside the air inlet channel 19. A vertical sliding groove 17 is provided on the inner side wall of the air inlet channel 19 near the connection with the movable slot 11. A horizontal slot 18 is provided on the outer side wall of the refrigerator 1 near the upper position of the movable slot 11. The horizontal slot 18 and the vertical sliding groove 17 are connected. The water-blocking component 4 includes two baffles that slide symmetrically inside the vertical sliding groove 17. A crossbar 411 is provided on one side of the outer wall of the water plate 41 near the interior of the horizontal slot 18. A frustum 412 is provided at one end of the crossbar 411 near the exterior of the refrigerator 1. A slider 413 is provided at the top and bottom of the water plate 41. Two elastic sleeves 42 are symmetrically arranged on one side of the outer wall of the refrigerator 1 near the outer side of the horizontal slot 18. An inclined guide plate 421 is provided on both sides of the two elastic sleeves 42. The elastic sleeves 42 are annular structures with notches. The outer circumferential surface of the elastic sleeve 42 forms a 150-degree angle with the inclined guide plate 421. The inner circumferential surface of the elastic sleeve 42 matches and fits with the outer circumferential surface of the frustum 412. Under the guidance of the two inclined guide plates 421, the frustum 412 is easily embedded inside the elastic sleeve 42 during horizontal movement. The elastic sleeve 42 limits the position of the frustum 412, ensuring the stability of the baffle plate 41. When the elastic sleeve 42 and the frustum 412 are engaged, the two baffle plates 41 are tightly joined together, blocking the air inlet channel 19. Two baffles 41 can be used to block the air inlet channel 19, thereby preventing water and dust mixture generated during blade cleaning from entering the interior of the refrigerator 1, and preventing the interior of the refrigerator 1 from being contaminated, corroded and damaged. A drainage groove 15 is provided at the bottom of the interior of the air inlet channel 19 near the baffle 41. An inclined drainage channel 16 connected to the drainage groove 15 is provided on one side of the outer wall of the refrigerator 1. The inclined drainage channel 16 is composed of a vertical channel and a horizontal channel that are vertically connected. The horizontal channel has an inclination angle of 15 degrees with the horizontal plane. To block and guide the wastewater generated during blade rinsing, in this embodiment, the opening and closing state of the air inlet channel 19 can be controlled by adjusting the position of the two baffles 41 inside the refrigerator 1. When the air inlet channel 19 is closed, it can block the water flow from entering the blades during rinsing, preventing the water and dust mixture generated during blade cleaning from entering the refrigerator 1, thus preventing contamination, corrosion, and damage to the refrigerator 1. It can also discharge the wastewater generated during cleaning from the refrigerator 1, ensuring the cleanliness of the blades and the refrigerator 1 as a whole. Specifically, before cleaning the blades on the impeller 35, the two baffles 41 are controlled to move and block the connection between the movable slot 11 and the air inlet channel 19, pushing the frustum 412, and the crossbar 4 With the connection of 11, the frustum 412 and the crossbar 411 move along the horizontal slot 18. At this time, the baffle plate 41 at one end of the crossbar 411 moves synchronously and moves along the vertical slide 17 until the frustum 412 at the other end of the crossbar 411 is engaged inside the elastic sleeve 42. The elastic sleeve 42 limits and fixes the frustum 412 to prevent the frustum 412 and the baffle plate 41 from changing position. After the two baffle plates 41 are tightly connected, they can block the air inlet channel 19. During the blade washing process, the water washed off the blades and the water flow down the drain trough 15 into the inclined drain channel 16 under the obstruction of the air inlet channel 19. Under the inclination of the inclined drain channel 16, the wastewater is discharged from the chiller 1.
