Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, specifically a vacuum pump set with output flow control function. Background Technology

[0002] Vacuum pumps create, maintain, or improve a vacuum environment in a closed space through mechanical, physical, or chemical methods. Essentially, they reduce the density of gas molecules by changing volume or directional movement of gas molecules, thereby achieving gas extraction. Therefore, Chinese invention patent (publication number: CN120007577A) discloses a box-type fully enclosed vacuum pump unit. This invention installs a heater on the pipeline between the screw vacuum pump and the Roots vacuum pump, and a temperature transmitter A is installed inside the screw vacuum pump. This allows the gas transported throughout the vacuum pump unit to be heated during use, preventing organic waste liquid contained in the exhaust gas from liquefying and precipitating into the system due to temperature drop during gas flow.

[0003] However, the vacuum pump unit has heat dissipation holes directly opened on the side panel of the housing, making it difficult to adjust the size of the heat dissipation holes. When the vacuum pump is left unused for a long time, some flying insects, as well as airborne fluff and dust, can easily enter the housing through the heat dissipation holes. This can cause impurities such as flying insects or dust to adhere to the surface of the vacuum pump unit's components inside the housing, which can easily lead to component failure and affect the normal operation of the vacuum pump unit. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum pump unit with output flow control function. Through the structural design of heat dissipation mesh, U-shaped bracket and pneumatic push rod, the size of heat dissipation holes on the box can be easily adjusted, effectively preventing flying insects and floating dust and other impurities from entering the box through the heat dissipation holes, thus solving the problem of difficulty in adjusting the size of heat dissipation holes.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a vacuum pump unit with output flow control function, including a housing. Rectangular through slots are provided on both side plates of the housing. Sliding grooves are provided on the side walls of the rectangular through slots. A second heat dissipation mesh is interference-fitted in the rectangular through slots, and a first heat dissipation mesh is slidably fitted in the rectangular through slots. The first heat dissipation mesh is located on one side of the second heat dissipation mesh. One end of the first heat dissipation mesh is fitted with the sliding groove. A guide groove is provided at the bottom of the first heat dissipation mesh. A receiving groove is provided at the bottom of the inner wall of the rectangular through slot. A pneumatic push rod is provided in the receiving groove. A U-shaped bracket is provided at the output end of the pneumatic push rod. The bottom end of the first heat dissipation mesh is fitted with the U-shaped bracket.

[0007] Furthermore, a slider is provided at one end of the heat dissipation mesh, and the slider cooperates with the slide groove.

[0008] Furthermore, two limiting grooves are opened at the bottom of the inner wall of the rectangular through groove, and two limiting plates are provided at the bottom of the U-shaped bracket, with the limiting plates cooperating with the limiting grooves.

[0009] Furthermore, a guide groove is provided at the bottom of the heat dissipation mesh, and an installation groove is provided on the U-shaped bracket. A row of guide wheels is evenly arranged in the installation groove, and the row of guide wheels cooperates with the guide groove.

[0010] Furthermore, a through groove is provided on the side wall of the rectangular through groove away from the slide rail. The heat dissipation mesh 1 cooperates with the through groove. A pull plate is provided at the end of the heat dissipation mesh 1 away from the slide rail. One end of the pull plate passes through the through groove to the outside of the box.

[0011] Furthermore, a cylinder is provided on the housing, an air inlet pipe is provided on one side of the cylinder, an air outlet pipe is provided on the housing, and a solenoid valve is provided on the air outlet pipe. The solenoid valve is a proportional solenoid valve.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of heat dissipation mesh one, U-shaped bracket and pneumatic push rod, pushes the U-shaped bracket upward by the output end of the pneumatic push rod, so that the heat dissipation holes on heat dissipation mesh one move upward and intersect with the heat dissipation mesh holes on heat dissipation mesh two. This allows for convenient adjustment of the size of the heat dissipation holes on the housing, effectively preventing flying insects and floating dust from entering the housing through the heat dissipation holes, preventing flying insects or floating dust from adhering to the surface of the vacuum pump unit components inside the housing, reducing the failure rate of the components on the vacuum pump unit inside the housing, and ensuring the normal operation of the vacuum pump unit.

[0014] 2. This utility model, through the structural design of guide wheels and through grooves, moves the heat dissipation mesh one upwards until it is completely aligned with the through groove. Then, by pulling the pull plate, the bottom end of the heat dissipation mesh one rolls between the guide groove and a row of guide wheels on the U-shaped bracket, allowing the heat dissipation mesh one to be moved out of the rectangular through groove. This makes it easy to disassemble and clean the heat dissipation mesh one, effectively reducing the difficulty of disassembling and assembling the heat dissipation mesh one, saving time and effort, and making the operation simple, thus effectively improving the cleaning and maintenance efficiency of the heat dissipation mesh one.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a vacuum pump set with output flow control function, including a housing 1, rectangular through slots 101 are provided on both side plates of the housing 1, and sliding grooves 102 are provided on the side walls of the rectangular through slots 101. A cylinder 6 is provided on the housing 1, an air inlet pipe is provided on one side of the cylinder 6, an air outlet pipe 7 is provided on the housing 1, and a solenoid valve is provided on the air outlet pipe 7. The solenoid valve is a proportional solenoid valve, which can control the displacement of the valve core and linearly adjust the valve opening to realize the control of the output flow of the vacuum pump set.

[0024] A second heat dissipation mesh 3 is interference-fitted inside the rectangular through groove 101, and a first heat dissipation mesh 2 is slidably fitted inside the rectangular through groove 101. The first heat dissipation mesh 2 is located on one side of the second heat dissipation mesh 3. One end of the first heat dissipation mesh 2 is fitted with the sliding groove 102. A sliding strip 201 is provided at one end of the first heat dissipation mesh 2. The sliding strip 201 is fitted with the sliding groove 102. The sliding strip 201 is a square strip, which can realize the sliding and separation of the sliding strip 201 in the sliding groove 102. A guide groove 202 is opened at the bottom end of the first heat dissipation mesh 2.

[0025] The bottom of the inner wall of the rectangular through groove 101 is provided with a receiving groove 103. A pneumatic push rod 5 is provided in the receiving groove 103. A U-shaped bracket 4 is provided at the output end of the pneumatic push rod 5. The bottom end of the heat dissipation mesh 2 cooperates with the U-shaped bracket 4. Two limiting grooves 104 are provided at the bottom of the inner wall of the rectangular through groove 101. Two limiting plates 403 are provided at the bottom of the U-shaped bracket 4. The limiting plates 403 cooperate with the limiting grooves 104 to ensure the stability of the U-shaped bracket 4 moving up and down in the rectangular through groove 101.

[0026] When the vacuum pump unit is not used for a long time, the pneumatic push rod 5 in the receiving groove 103 is activated, causing the output end of the pneumatic push rod 5 to push the U-shaped bracket 4 upward. Through the cooperation of the limiting plate 403 and the limiting groove 104, the U-shaped bracket 4 moves stably upward in the rectangular through groove 101. Through the cooperation of the slide bar 201 and the slide groove 102, the heat dissipation mesh 2 moves upward in the rectangular through groove 101 under the push of the U-shaped bracket 4. This causes the heat dissipation holes on the heat dissipation mesh 2 to intersect with the heat dissipation mesh holes on the heat dissipation mesh 3. The size of the heat dissipation gap formed by the intersect between the heat dissipation mesh 2 and the heat dissipation mesh 3 gradually changes until the top of the heat dissipation mesh 2, pushed by the U-shaped bracket 4, contacts the top inner wall of the rectangular through groove 101. At this time, the heat dissipation holes on the heat dissipation mesh 2 and the heat dissipation mesh 3 are completely intersected. At this time, the heat dissipation gap formed by the intersect between the heat dissipation mesh 2 and the heat dissipation mesh 3 disappears, thereby closing the heat dissipation gap on the housing 1.

[0027] The bottom of the heat dissipation mesh 2 is provided with a guide groove 202, and the U-shaped bracket 4 is provided with an installation groove 401. A row of guide wheels 402 are evenly arranged in the installation groove 401. The row of guide wheels 402 cooperate with the guide groove 202, which can facilitate the heat dissipation mesh 2 to slide out of the rectangular through groove 101. A through groove 105 is provided on the side wall of the rectangular through groove 101 away from the sliding groove 102. The heat dissipation mesh 2 cooperates with the through groove 105. A pull plate 203 is provided at the end of the heat dissipation mesh 2 away from the sliding strip 201. One end of the pull plate 203 passes through the through groove 105 to the outside of the box 1, which can facilitate the pulling of the heat dissipation mesh 2 through the through groove 105 to move it out of the rectangular through groove 101.

[0028] When the heat dissipation mesh 2 needs to be disassembled and cleaned after long-term use, the output end of the pneumatic push rod 5 is used to move the heat dissipation mesh 2 upwards until its top end contacts the top inner wall of the rectangular through groove 101. At this time, the heat dissipation mesh 2 is completely aligned with the through groove 105. Then, the pull plate 203 is pulled, so that the bottom end of the heat dissipation mesh 2 rolls between the guide groove 202 and a row of guide wheels 402 on the U-shaped bracket 4, thereby making the heat dissipation mesh 2 slide in the through groove 105, so that the slide bar 201 disengages from the slide groove 102, until the heat dissipation mesh 2 is completely removed from the rectangular through groove 101 through the through groove 105, thus realizing the convenient disassembly of the heat dissipation mesh 2. Similarly, when installing the heat dissipation mesh 2, the above operation is repeated in reverse order to realize the installation of the heat dissipation mesh 2.
