Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a dry ice air compressor cleaning integrated machine. Background Technology

[0002] A dry ice cleaning machine is a device that uses solid carbon dioxide (dry ice) for cleaning. Its working principle is to spray dry ice particles onto the surface to be cleaned by high-pressure air. Taking advantage of the property of dry ice to sublimate rapidly at room temperature, it absorbs a large amount of heat and produces a low-temperature effect, which freezes, embrittles and eventually peels off the dirt.

[0003] Chinese utility model patent CN216369338U discloses a dry ice cleaning machine, which includes a body and a dry ice chamber movably disposed within the body and open at both the top and bottom. An intermittent feeding mechanism is connected below the dry ice chamber. An air inlet pipe and a spray pipe are respectively connected to the lower end face of the intermittent feeding mechanism. Vibration mechanisms are provided on the left and right sides of the dry ice chamber. A mesh is provided inside the dry ice chamber. In use, dry ice is placed into the dry ice chamber. An air compressor is connected to the air inlet pipe, and a spray gun is connected to the spray pipe. Then, the air compressor, vibration mechanism, and intermittent feeding mechanism are started. The vibration mechanism can drive the dry ice chamber to vibrate, causing the dry ice located above the mesh to vibrate and then fall through the mesh of the mesh into the dry ice chamber below and into the intermittent feeding mechanism. Intermittent feeding is achieved through the intermittent feeding mechanism. At this time, high-pressure air enters from the air inlet pipe, carries away the dry ice from the spray pipe, and finally sprays it out through the spray gun.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the air inlet pipe is connected to an external air compressor, which provides high-pressure air to blow out the gas after the dry ice sublimates under high pressure to rinse the items to be cleaned. When using a dry ice cleaner to clean items in different locations, it is necessary to move the dry ice cleaner and carry an air compressor. At the same time, a connecting pipe is used to connect the air compressor to the air inlet pipe of the dry ice cleaner, which makes the operation relatively complicated. Therefore, the relevant technologies need to be improved and designed. Utility Model Content

[0005] To solve the above problems, this utility model provides a dry ice air compressor cleaning integrated machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dry ice air compressor cleaning integrated machine, comprising a machine body, wherein an installation chamber and a working chamber are provided inside the machine body, an air compressor unit is provided in the installation chamber, a pressure holding tank connected to the output pipe of the air compressor unit and a hopper for storing dry ice are provided in the working chamber, and a material tray unit for receiving dry ice falling from the hopper is also provided in the working chamber, an air inlet pipe is fixed and connected to the top of the material tray unit, the air inlet pipe is connected to the output pipe of the pressure holding tank through a connecting pipe, a feeding pipe for blowing out biochemical dry ice particles is fixed and connected to the bottom of the material tray unit, and a perforation for the connector of the feeding pipe to pass through is provided on the side wall of the machine body.

[0007] By adopting the above technical solution, the air compressor unit is integrated into the air compressor cleaner. After the air compressor unit is working, the air pressure output is collected in the pressure tank, and then transported to the material tray unit through the connecting pipe and the air inlet pipe. This provides high-pressure gas to the dry ice particles received by the material tray unit, so that the dry ice particles form a high-pressure airflow and are discharged through the feeding pipe. Finally, the ice is discharged by the ice discharge gun connected to the feeding pipe and cleans the items to be cleaned. This changes the traditional separate design of the air compressor and the dry ice cleaner, reducing the difficulty of carrying the equipment.

[0008] Furthermore, the material tray unit includes an upper tray fixed in the working chamber and located near the bottom of the hopper, and a lower tray detachably connected to the bottom of the upper tray. The bottom of the upper tray is provided with a mounting groove. The material tray unit also includes a turntable rotatably mounted on the lower tray and extending into the mounting groove. The top of the upper tray is provided with a material discharge through hole communicating with the mounting groove. The top of the turntable is provided with a plurality of receiving holes evenly distributed about the axis of the turntable. The orthographic projection of the output end of the air inlet pipe is located within the annular area of ​​the plurality of receiving holes. The connection hole between the feed end of the feed pipe and the lower tray corresponds to the position of the output end of the air inlet pipe.

[0009] Furthermore, a geared motor for driving the turntable to rotate is fixed in the installation chamber.

[0010] By adopting the above technical solution, when the dry ice particles in the receiving hole corresponding to the air inlet pipe are consumed, the geared motor works and drives the turntable to rotate, so that the dry ice particles in the receiving hole corresponding to the air inlet pipe are replenished in time, ensuring the smooth operation of the dry ice cleaning machine.

[0011] Furthermore, an upper groove is provided at the bottom of the upper plate near the output end of the air inlet pipe, and an upper annular member is provided in the upper groove, which surrounds the axis of the output end of the air inlet pipe. The bottom of the upper annular member abuts against the top of the turntable, and an upper annular rubber ring for sealing is provided between the top of the upper annular member and the inner top wall of the upper groove; a lower groove is provided at the top of the lower plate near the feed end of the feed pipe, and a lower annular member is provided in the lower groove, which surrounds the axis of the output end of the air inlet pipe. The top of the lower annular member abuts against the bottom of the turntable, and a lower annular rubber ring for sealing is provided between the bottom of the lower annular member and the inner bottom wall of the lower groove.

[0012] By adopting the above technical solution, the high-pressure gas provided by the air inlet pipe can smoothly eject the dry ice in the corresponding receiving hole from the feed pipe under high pressure.

[0013] Furthermore, a pressure relief notch is provided on the lower plate near the lower annular component.

[0014] By adopting the above technical solution, the pressure relief notch plays a good role in balancing air pressure, reducing the probability of the air inlet pipe and feed pipe rupture due to excessive gas pressure provided by the air compressor unit and pressure tank.

[0015] Furthermore, a partition net is installed inside the hopper, and a material distribution rack is fixed inside the hopper near its discharge port.

[0016] By adopting the above technical solution, the partition mesh allows dry ice particles to be temporarily stored on the vertical bars of the mesh, reducing the probability of clogging the hopper outlet due to dry ice absorbing water and freezing. The distribution rack allows the dry ice particles to be dispersed into multiple receiving holes corresponding to the hopper outlet.

[0017] Furthermore, the bottom of the machine body is evenly provided with multiple air inlets communicating with the installation chamber, the top of the machine body is provided with an air outlet communicating with the installation chamber, and a cooling fan is fixed at the top of the machine body corresponding to the air outlet.

[0018] By adopting the above technical solution, it is beneficial to dissipate the heat generated by the air compressor unit during operation.

[0019] Furthermore, the bottom of the machine body is provided with four rectangular array of universal wheels with brakes, and a handle is fixed on the side wall of the machine body near its bottom.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, the air compressor unit is integrated into the air compressor cleaner. After the air compressor unit is working, the air pressure output is collected in the pressure tank, and then transported to the material tray unit through the connecting pipe and the air inlet pipe. This provides high-pressure gas to the dry ice particles received by the material tray unit, so that the dry ice particles form a high-pressure airflow and are discharged through the feeding pipe. Finally, the ice is discharged through the ice discharge gun connected to the feeding pipe and cleans the items to be cleaned. This changes the traditional separate design of the air compressor and the dry ice cleaner, and reduces the difficulty of carrying the equipment.

[0022] 2. In this application, when the dry ice particles in the receiving hole corresponding to the air inlet pipe are consumed, the geared motor works and drives the turntable to rotate, so that the dry ice particles in the receiving hole corresponding to the air inlet pipe are replenished in time, ensuring the smooth operation of the dry ice cleaning machine.

[0023] 3. In this application, the pressure relief notch plays a good role in balancing air pressure, reducing the probability of the air inlet pipe and feed pipe rupture due to excessive gas pressure provided by the air compressor unit and pressure tank. Attached Figure Description

Detailed Implementation

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] like Figure 1-9 As shown in the embodiment of this application, a dry ice air compressor cleaning integrated machine is disclosed, including a body 1. The body 1 is provided with an installation chamber 11 and a working chamber 12. An air compressor unit 2 is provided in the installation chamber 11. The working chamber 12 is provided with a pressure tank 3 connected to the output pipe of the air compressor unit 2 (a pressure gauge 13 for monitoring the air pressure in the pressure tank 3 is provided on the side wall of the body 1) and a hopper 4 for storing dry ice (an ice filling port 14 for adding dry ice to the hopper 4 is provided on the top of the body 1). The working chamber 12 is also provided with a receiving device for receiving the dry ice from the hopper 4. The dry ice feeding tray unit 5 has an air inlet pipe 15 fixed to its top and connected to it. The air inlet pipe 15 is connected to the output pipe of the pressure tank 3 through a connecting pipe (not shown in the figure, the connecting pipe is equipped with a solenoid valve for controlling the pressure, and the machine body 1 is equipped with a pressure regulating knob 16 for controlling the operation of the solenoid valve). The bottom of the feeding tray unit 5 is fixed to and connected to a feeding pipe 6 for blowing out the biochemical dry ice particles. The side wall of the machine body 1 is provided with a perforation for the connector of the feeding pipe 6 to pass through. The end of the feeding pipe 6 located outside the machine body 1 is the ice outlet.

[0036] The air compressor unit 2 is integrated into the air compressor cleaner. After the air compressor unit 2 is working, the air pressure output is collected in the pressure tank 3, and then transported to the material tray unit 5 through the connecting pipe and the air inlet pipe 15. This provides high-pressure gas to the dry ice particles received by the material tray unit 5, so that the dry ice particles form a high-pressure airflow and are discharged through the feeding pipe 6. Finally, the ice is discharged by the ice gun connected to the feeding pipe 6 and cleans the items to be cleaned. This changes the traditional design of separate air compressor and dry ice cleaner, reducing the difficulty of carrying the equipment.

[0037] The material tray unit 5 includes an upper tray 51 fixed in the working chamber 12 and located near the bottom of the hopper 4, and a lower tray 52 detachably connected to the bottom of the upper tray 51. The bottom of the upper tray 51 is provided with a mounting groove 510. The material tray unit 5 also includes a turntable 53 rotatably mounted on the lower tray 52 and extending into the mounting groove 510. The top of the upper tray 51 is provided with a material discharge through hole 511 communicating with the mounting groove 510. The top of the turntable 53 is provided with a plurality of receiving holes 531 evenly distributed about the axis of the turntable 53. The orthographic projection of the output end of the air inlet pipe 15 is located in the annular area of ​​the plurality of receiving holes 531. The connection hole between the feed end of the feed pipe 6 and the lower tray 52 corresponds to the position of the output end of the air inlet pipe 15. A geared motor 17 for driving the turntable 53 to rotate is fixed in the mounting chamber 11.

[0038] When the dry ice particles in the receiving hole 531 corresponding to the air inlet pipe 15 are consumed, the geared motor 17 works and drives the turntable 53 to rotate, so that the dry ice particles in the receiving hole 531 corresponding to the air inlet pipe 15 are replenished in time, ensuring the smooth operation of the dry ice cleaning machine.

[0039] To ensure that the high-pressure gas provided by the air inlet pipe 15 can smoothly eject the dry ice from the corresponding receiving hole 531 through the feed pipe 6, an upper groove 512 is provided at the bottom of the upper plate 51 near the output end of the air inlet pipe 15. An upper annular member 7 is provided in the upper groove 512, which surrounds the axis of the output end of the air inlet pipe 15. The bottom of the upper annular member 7 abuts against the top of the turntable 53, and an upper annular rubber ring 71 for sealing is provided between the top of the upper annular member 7 and the inner top wall of the upper groove 512. A lower groove 521 is provided at the top of the lower plate 52 near the feed end of the feed pipe 6. A lower annular member 8 is provided in the lower groove 521, which surrounds the axis of the output end of the air inlet pipe 15. The top of the lower annular member 8 abuts against the bottom of the turntable 53, and a lower annular rubber ring 81 for sealing is provided between the bottom of the lower annular member 8 and the inner bottom wall of the lower groove 521.

[0040] To ensure a stable airflow output within the air inlet pipe 15 and the feed pipe 6, and to reduce the probability of bursting, a pressure relief notch 522 (small pressure relief notch 522) is provided on the lower plate 52 near the lower annular component 8. When the air pressure is too high, some airflow seeps out from the gap between the upper annular component 7 and the turntable 53 and the gap between the lower annular component 8 and the turntable 53, and the pressure is released through the pressure relief notch 522.

[0041] A partition net 41 is installed inside the hopper 4, and a distribution rack 42 is fixed inside the hopper 4 near its outlet. The partition net 41 allows dry ice particles to be temporarily stored on the vertical rods of the partition net 41, reducing the probability of the dry ice absorbing water and freezing, thus clogging the outlet of the hopper 4. The distribution rack 42 allows the dry ice particles to be dispersed into the multiple receiving holes 531 corresponding to the outlet of the hopper 4.

[0042] Multiple air inlets 18 that communicate with the installation chamber 11 are evenly arranged at the bottom of the machine body 1, and an air outlet 19 that communicates with the installation chamber 11 is arranged at the top of the machine body 1. A cooling fan 191 is fixed at the position corresponding to the air outlet 19 at the top of the machine body 1, which is conducive to the dissipation of heat generated by the air compressor unit 2 during operation.

[0043] To facilitate movement of the dry ice air compressor cleaning unit, four rectangular arrayed casters 9 with brakes are installed at the bottom of the unit body 1, and handles 10 are fixed on the side wall of the unit body 1 near its bottom. To minimize the probability of blockage at the discharge port of the hopper 4, a vibration motor 43 is fixed to the outer wall of the hopper 4.

[0044] The working principle of the dry ice air compressor cleaning integrated machine in this embodiment is as follows: the air compressor unit 2 is integrated into the air compressor cleaning machine. After the air compressor unit 2 is working, the air pressure output is collected into the pressure tank 3, and then transported to the material tray unit 5 through the connecting pipe and the air inlet pipe 15. This provides high-pressure gas to the dry ice particles received by the material tray unit 5, so that the dry ice particles form a high-pressure airflow and are discharged through the feeding pipe 6. Finally, the ice is discharged through the ice discharge gun connected to the feeding pipe 6 and cleans the items to be cleaned. This changes the traditional separate design of the air compressor and the dry ice cleaning machine, reducing the difficulty of carrying the equipment.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
