[0013] Beneficial effects

[0014] The utility model provides a kind of refrigerating machine used in high oil mist environment.Compared with prior art, it has the following beneficial effects:

[0015] 1. This refrigeration unit, used in high oil mist environments, works by filtering large oil mist particles from stainless steel buffer filters as air containing oil mist enters the separator through the intake pipe. The pre-filtered oil mist then enters an electrostatic filter, where a high-voltage electric field is applied. The oil mist enters the charged region and is charged by the ions present. The charged oil mist then passes through a collection plate, which carries the opposite charge to the electrostatic filter, adsorbing the charged oil mist. Finally, a stainless steel post-filter filters out any remaining charged particles, separating the oil mist from the air. The clean air then enters the condenser inside the refrigeration unit, preventing condenser blockage. This separation mechanism, utilizing stainless steel buffer filters, electrostatic filters, collection plates, and a stainless steel post-filter, filters, adsorbs, and separates oil mist from the air in high oil mist environments, preventing oil mist from entering the condenser and causing blockage, thus extending the refrigeration unit's lifespan.

[0016] 2. This refrigeration unit, designed for use in high oil mist environments, utilizes a mobile motor to drive a rotating rod and worm gear. The worm gear's rotation causes two sets of worm wheels to rotate synchronously, which in turn drives a transmission screw. This rotation of the transmission screw causes the transmission plate and the connecting plates on both sides to slide downwards synchronously. The connecting plates then slide on the surface of the limiting rods. This sliding motion causes the connecting rods and moving wheels at both ends to slide downwards synchronously, allowing the moving wheels to slide within the slots and eventually contact the ground. These four sets of moving wheels synchronously lift the base and the refrigeration unit, propelling the unit to the high oil mist environment. The mobile mechanism, driven by the mobile motor, allows for free adjustment of the height of the four sets of moving wheels. By synchronously lifting the base and the refrigeration unit, the unit's position can be easily adjusted by the operator, enhancing its flexibility. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A refrigeration unit for use in high oil mist environments includes a base 1, a refrigeration unit body 2 mounted on top of the base 1, a moving mechanism 3 inside the base 1, and a separation mechanism 4 on one side of the refrigeration unit body 2 along a first direction. The separation mechanism 4 includes:

[0026] The separation assembly 41 includes a separation box 411 installed on the refrigerator body 2. An air inlet pipe 412 is installed on the side of the separation box 411 away from the refrigerator body 2. Mounting plates 413 are fixedly connected to the top and bottom of the inner cavity of the separation box 411. Along the first direction, a stainless steel buffer filter plate 414, an electrostatic filter screen 415, a collection plate 416 and a stainless steel post-filter plate 417 are installed sequentially on the inside of the mounting plate 413 in the direction that gradually approaches the refrigerator body 2. The side of the separation box 411 near the refrigerator body 2 is fixedly connected to the inside of the refrigerator body 2 through a connecting pipe 418.

[0027] Support component 42 is located at the bottom of separation box 411.

[0028] One end of the connecting pipe 418 extends through to the interior of the refrigerator body 2; the stainless steel buffer filter plate 414 is mainly used to filter large particles of oil mist in the air; the electrostatic filter screen 415 is mainly used to add charge to the oil mist in the air; the collection plate 416 is mainly used to adsorb charged oil mist; the stainless steel post-filter plate 417 is mainly used to filter the remaining charged particles in the air.

[0029] In this embodiment, the support assembly 42 includes a support plate 421 installed at the bottom of the separation box 411. A support frame 422 is fixedly connected to the bottom of the support plate 421, and one side of the support frame 422 is fixedly connected to the left side of the refrigerator body 2.

[0030] When air containing oil mist enters the separator 411 through the intake pipe 412, it first passes through a stainless steel buffer filter plate 414 to filter large oil mist particles. After preliminary filtration, the oil mist enters an electrostatic filter 415, where a high-voltage electric field is added. The oil mist enters the charged region and is charged by the ions present. The charged oil mist then passes through a collection plate 416, which carries a charge opposite to that of the electrostatic filter 415. The collection plate 416 adsorbs the charged oil mist. Finally, the air passes through a stainless steel post-filter plate 417. The remaining charged particles in the air are filtered to separate the oil mist from the air. Finally, the clean air enters the condenser inside the refrigerator body 2, preventing the condenser from becoming dirty and clogged. By setting up a separation mechanism 4, using a stainless steel buffer filter plate 414, an electrostatic filter screen 415, a collection plate 416, and a stainless steel post-filter plate 417, the oil mist in the high oil mist environment can be filtered, adsorbed, and separated, so that the oil mist is separated from the air. This prevents the air containing oil mist from entering the condenser inside the refrigerator body 2 and causing the condenser to become dirty and clogged, thereby improving the service life of the refrigerator.

[0031] In this embodiment, the moving mechanism 3 includes a moving motor 31 installed on the left side of the base 1. One end of the output shaft of the moving motor 31 is fixedly connected to a rotating rod 32 via a coupling. A worm gear 33 is fixedly connected to the surface of the rotating rod 32. The surface of the worm gear 33 is connected to a connecting plate 35 via a transmission assembly 34. A connecting rod 36 is fixedly connected to the bottom of the connecting plate 35. A moving wheel 37 is fixedly connected to the bottom end of the connecting rod 36.

[0032] The mobile motor 31 is a three-phase asynchronous motor and is connected to an external circuit via wires; the rotating rod 32 rotates inside the base 1.

[0033] In this embodiment, the transmission assembly 34 includes a transmission screw 341 rotatably mounted at the bottom of the inner cavity of the base 1. A worm gear 342 is fixedly connected to the surface of the transmission screw 341. The surface of the worm gear 342 meshes with the surface of the worm 33. A transmission plate 343 is threadedly connected to the surface of the transmission screw 341. One end of the transmission plate 343 is fixedly connected to one side of the connecting plate 35.

[0034] Two sets of worm gear 33, worm wheel 342 and transmission screw 341 are provided; transmission plate 343 is used to connect and fix the connecting plates 35 on both sides.

[0035] In this embodiment, a limiting rod 5 is fixedly connected to the bottom of the inner cavity of the base 1, and the surface of the limiting rod 5 is slidably connected to the inside of the connecting plate 35.

[0036] The limiting rod 5 is used to slide and limit the connecting plate 35.

[0037] In this embodiment, a support leg 6 is fixedly connected to the bottom of the base 1. The support leg 6 has a slot inside, and the movable wheel 37 is disposed inside the slot.

[0038] By starting the mobile motor 31, the rotating rod 32 and worm gear 33 are driven to rotate. The rotation of the worm gear 33 drives the two sets of worm wheels 342 to rotate synchronously. The rotation of the worm wheels 342 drives the transmission screw 341 to rotate synchronously. The rotation of the transmission screw 341 causes the transmission plate 343 and the connecting plates 35 on both sides to slide downward synchronously. This causes the connecting plate 35 to slide on the surface of the limit rod 5. The sliding of the connecting plate 35 causes the connecting rods 36 at both ends and the moving wheels 37 to slide downward synchronously. This causes the moving wheels 37 to slide inside the slot, and then the surface of the moving wheels 37 to contact the ground. The four sets of moving wheels 37 synchronously lift the base 1 and the refrigerator body 2 as a whole, and then push the refrigerator body 2 to the working location with a high oil mist environment. By setting up the moving mechanism 3, the height of the four sets of moving wheels 37 can be freely adjusted by the mobile motor 31. The four sets of moving wheels 37 synchronously lift the base 1 and the refrigerator body 2 as a whole, which makes it easy for the staff to move and adjust the position of the refrigerator body 2, thus improving the flexibility of the refrigerator.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] First, the moving motor 31 is started, driving the rotating rod 32 and worm gear 33 to rotate. The rotation of the worm gear 33 drives the two sets of worm wheels 342 to rotate synchronously. The rotation of the worm wheels 342 drives the transmission screw 341 to rotate synchronously. The rotation of the transmission screw 341 causes the transmission plate 343 and the connecting plates 35 on both sides to slide downward synchronously, allowing the connecting plate 35 to slide on the surface of the limit rod 5. The sliding of the connecting plate 35 causes the connecting rods 36 at both ends and the moving wheels 37 to slide downward synchronously, allowing the moving wheels 37 to slide inside the empty groove, thus bringing the surface of the moving wheels 37 into contact with the ground. The four sets of moving wheels 37 synchronously lift the base 1 and the refrigerator body 2, then push the refrigerator body 2 to the working location with a high oil mist environment. Then, the moving motor 31 is started to rotate in the opposite direction, causing the moving wheels 37 to retract into the empty groove. The support legs 6 support the base. 1. Supports the refrigeration unit 2. When the refrigeration unit 2 operates in a high oil mist environment, the air containing oil mist enters the separation box 411 through the intake pipe 412. Then, it first passes through the stainless steel buffer filter plate 414 to filter large particles of oil mist. After the initial filtration, the oil mist enters the electrostatic filter 415. At this time, a high voltage electric field is added to the electrostatic filter 415. After the oil mist enters the charged area, it is charged by the ions present therein. Then, the charged oil mist passes through the collection plate 416. Since the collection plate 416 has the opposite charge to the electrostatic filter 415, the charged oil mist is adsorbed by the collection plate 416. Finally, the remaining charged particles in the air are filtered through the stainless steel post-filter plate 417, realizing the separation of oil mist and air. Finally, the clean air enters the condenser inside the refrigeration unit 2 to prevent the condenser from getting dirty and clogged.
