Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for dry vacuum pumps, and in particular to a housing for a dry vacuum pump with heat dissipation function. Background Technology

[0002] Oil-free dry mechanical vacuum pumps, also known as dry mechanical pumps, are mechanical vacuum pumps that can start pumping gas from atmospheric pressure and discharge the pumped gas directly into the atmosphere. There is no oil or other working medium in the pump chamber, and the ultimate pressure of the pump is on the same order of magnitude or close to that of oil-sealed vacuum pumps.

[0003] Dry vacuum pumps generate a lot of heat during operation. Existing dry vacuum pumps are usually equipped with cooling shells for heat dissipation. However, traditional dry vacuum pump shells are often fixed with simple bolts or clips, which is not only cumbersome to operate, but also makes it difficult to ensure the stability and adaptability of the dry vacuum pump. At the same time, for pump bodies of different sizes and specifications, traditional shells often cannot provide suitable clamping force and stability. Furthermore, traditional dry vacuum pump shells have low heat dissipation efficiency, leading to heat accumulation and affecting the performance and lifespan of the dry vacuum pump. Utility Model Content

[0004] The purpose of this invention is to provide a housing for a dry vacuum pump with heat dissipation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a breathable outer shell, a clamping assembly is provided inside the breathable outer shell, a dry vacuum pump is provided inside the clamping assembly, and a heat dissipation assembly is provided on the top of the breathable outer shell.

[0006] As a preferred embodiment of the present invention, the clamping assembly includes a T-shaped mounting groove formed in a ventilated outer shell, a pair of support seats symmetrically arranged in the T-shaped mounting groove, a bidirectional lead screw inserted between the two support seats, a pair of driving blocks spirally and symmetrically sleeved on the outer side of the bidirectional lead screw, a pair of moving tracks symmetrically arranged in the T-shaped mounting groove, and both driving blocks slidably arranged on the moving tracks.

[0007] As a preferred embodiment of this invention, each of the two drive blocks is provided with a fixed seat on its top, and each of the two fixed seats is provided with a melamine sponge pad on one side, with the dry vacuum pump located between the two fixed seats.

[0008] In a preferred embodiment of this utility model, a gear is sleeved on the outer side of one end of the bidirectional lead screw, a telescopic cylinder is provided on one side of the T-shaped mounting groove, a mounting plate is provided on the top of the telescopic rod of the telescopic cylinder, a rack is provided on the side of the mounting plate away from the telescopic cylinder, a second moving track is provided in the T-shaped mounting groove, the second moving track is located on one side of the first moving track, the included angle between the first moving track and the second moving track is 90 degrees, the rack is slidably mounted on the second moving track, and the gear meshes with the rack.

[0009] As a preferred embodiment of the present invention, the heat dissipation component includes a mounting box disposed on the top of the ventilated outer shell, a protective plate disposed at the bottom of the mounting box, and a ventilation opening provided on the protective plate.

[0010] As a preferred embodiment of this utility model, a motor is provided on the top surface of the mounting box, a fan shaft is provided on the transmission end of the motor, and several fan blades are provided on the outer side of the fan shaft.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. This utility model achieves efficient and stable clamping of a dry vacuum pump by setting up a clamping assembly. The combination of a bidirectional lead screw and a drive block converts the rotational motion into linear motion, allowing the two fixed seats to synchronously and smoothly approach or move away from the dry vacuum pump, greatly simplifying the clamping and releasing process. At the same time, the melamine sponge pad not only enhances the clamping force, but also helps to disperse the heat generated by the dry vacuum pump during operation due to its good air permeability, improving the overall heat dissipation effect of the equipment. In addition, the linkage mechanism of gears, bidirectional lead screws, telescopic cylinders and racks enables the clamping assembly to automatically adjust the distance between the two fixed seats and the clamping force, adapting to dry vacuum pumps of different sizes and specifications, and improving the flexibility and applicability of the ventilated shell.

[0012] 2. By setting up a heat dissipation component, the motor-driven fan shaft and fan blades can generate airflow, which is directly blown onto the dry vacuum pump through the ventilation port at the bottom of the mounting box, effectively accelerating the heat dissipation and reducing the operating temperature of the equipment. Secondly, the protective plate not only protects the motor, fan shaft and fan blades from interference from the external environment, but also optimizes the airflow path and improves heat dissipation efficiency through the cooperation of its ventilation port and the round hole on the ventilated shell.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figures 1-5 As shown, the present invention proposes a housing for a dry vacuum pump with heat dissipation function, which includes a ventilated housing 1, a clamping assembly 2 disposed inside the ventilated housing 1, a dry vacuum pump 3 disposed inside the clamping assembly 2, and a heat dissipation assembly 4 disposed on the top of the ventilated housing 1.

[0017] The clamping assembly 2 includes a T-shaped mounting groove 27 formed inside the ventilated housing 1. The T-shaped mounting groove 27 provides a mounting base for other components in the clamping assembly 2. A pair of support seats 21 are symmetrically arranged inside the T-shaped mounting groove 27. The support seats 21 serve as support points for the bidirectional lead screw 22, ensuring that the bidirectional lead screw 22 can rotate smoothly. The bidirectional lead screw 22 is inserted between the two support seats 21. By rotating, the rotational motion of the bidirectional lead screw 22 is converted into the linear motion of the drive block 23, realizing the simultaneous clamping or release of the two fixed seats 24, thereby facilitating the assembly and disassembly of the dry vacuum pump 3. A pair of drive blocks 23 are spirally and symmetrically sleeved on the outside of the bidirectional lead screw 22. The drive blocks 23 provide a mounting base for the fixed seats 24. A pair of moving rails 26 are symmetrically arranged inside the T-shaped mounting groove 27. Both drive blocks 23 are slidably mounted on the moving rails 26. The moving rails 26 provide a sliding path for the drive blocks 23, ensuring that the drive blocks 23 can move smoothly.

[0018] Both drive blocks 23 are equipped with a fixed seat 24 on their tops. The fixed seat 24 is used to clamp the dry vacuum pump 3 to ensure its stable operation. A melamine sponge pad 25 is provided on one side of each of the two fixed seats 24. The dry vacuum pump 3 is located between the two fixed seats 24. The melamine sponge pad 25 increases the friction between the dry vacuum pump 3 and the fixed seat 24 to prevent the dry vacuum pump 3 from slipping during operation. At the same time, it has good air permeability, which helps to absorb and disperse heat.

[0019] A gear 28 is fitted on the outer side of one end of the bidirectional lead screw 22. The gear 28 meshes with the rack 211. When the rack 211 moves, it drives the gear 28 to rotate, thereby driving the bidirectional lead screw 22 to rotate. A telescopic cylinder 29 is provided on one side of the T-shaped mounting groove 27. The telescopic cylinder 29 provides power, which drives the mounting plate 210 to move through the extension and retraction of the telescopic rod, thereby driving the rack 211 to move along the moving track 212. The top of the telescopic rod of the telescopic cylinder 29 is provided with a mounting plate 210. The mounting plate 210 connects the telescopic cylinder 29 and the rack 211, transmitting the power of the telescopic cylinder 29. The mounting plate 210 is located away from the extension rod. A rack 211 is provided on one side of the cylinder 29. When the mounting plate 210 moves, the rack 211 moves accordingly and meshes with the gear 28 to transmit power. A second moving track 212 is provided in the T-shaped mounting groove 27. The second moving track 212 is located on one side of the first moving track 26. The angle between the first moving track 26 and the second moving track 212 is 90 degrees. The rack 211 is slidably mounted on the second moving track 212. The gear 28 meshes with the rack 211. The second moving track 212 provides a sliding path for the rack 211 to ensure that the rack 211 can move smoothly.

[0020] The heat dissipation assembly 4 includes a mounting box 41 located on the top of the ventilated housing 1. The mounting box 41 provides a mounting base for other components in the heat dissipation assembly 4. A protective plate 42 is provided at the bottom of the mounting box 41. A vent 43 is provided on the protective plate 42. The vent 43 on the protective plate 42 allows airflow to pass through, accelerating the removal of heat generated by the dry vacuum pump 3 during operation from the ventilated housing 1.

[0021] A motor 44 is installed on the top surface of the mounting box 41. The motor 44 provides power to drive the fan shaft 45 to rotate. The transmission end of the motor 44 is equipped with the fan shaft 45. Several fan blades 46 are installed on the outside of the fan shaft 45. When the motor 44 drives the fan shaft 45 to rotate, the fan blades 46 will rotate accordingly, generating airflow, which is blown to the dry vacuum pump 3 through the vent 43 to accelerate the removal of heat.

[0022] In use, the user first places the dry vacuum pump 3 into the ventilated housing 1, and then starts the telescopic cylinder 29. The telescopic rod of the telescopic cylinder 29 drives the mounting plate 210 to move. The mounting plate 210 transmits the power of the telescopic cylinder 29 to the rack 211, so that the rack 211 moves along the second moving track 212. The rack 211 meshes with the gear 28. When the rack 211 moves, it can drive the gear 28 to rotate. The gear 28 transmits power to the double-acting screw 22, driving the double-acting screw 22 to rotate. The rotational motion of the double-acting screw 22 is converted into the linear motion of the drive block 23, so that the two drive blocks 23 move closer or further away from each other along the first moving track 26. This allows the two fixed seats 24 to clamp or release the dry vacuum pump 3 at the same time, which helps the user to quickly assemble and disassemble the dry vacuum pump 3, and also improves the flexibility and applicability of the ventilated housing 1.

[0023] After the two mounting bases 24 securely clamp the dry vacuum pump 3, the melamine sponge pad 25 on one side of the mounting base 24 not only increases the friction between the dry vacuum pump 3 and the mounting base 24, but also has good air permeability, which helps to disperse the heat generated by the dry vacuum pump 3 during operation and avoid local overheating of the dry vacuum pump 3. When the dry vacuum pump 3 has a high operating temperature due to long-term operation, the user can start the heat dissipation component 4, which drives the fan shaft 45 to rotate through the motor 44. The fan shaft 45 drives several fan blades 46 to rotate, thereby generating airflow. The airflow blows towards the dry vacuum pump 3 through the vent 43, accelerating the discharge of the heat generated by the dry vacuum pump 3 during operation through the round hole on the side of the vent housing 1.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
