Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum pump technology, and in particular to an air-cooled dry vacuum pump. Background Technology
[0002] Air-cooled dry vacuum pumps represent an advanced vacuum pump technology that eliminates traditional oil lubrication and water cooling methods, employing dry exhaust gas cooling technology and an oil-free operation design. The working principle of this pump is primarily based on physical adsorption and compression. A high-speed rotating rotor generates airflow, and the collision and physical adsorption of gas molecules by the airflow extracts the gas, creating a vacuum. Air-cooled dry vacuum pumps are compact and small in size, with their internal rotor surface covered with highly efficient adsorption material, enabling rapid adsorption of gas molecules.
[0003] In the prior art, for example, Chinese Patent No. CN221121527U discloses an air-cooled self-circulating water ring vacuum pump unit, including a channel steel base frame. A water ring vacuum pump and a motor are mounted on the top of the channel steel base frame. Several evenly distributed positioning beams are welded inside the channel steel base frame. An assembly seat located at the bottom of the water ring vacuum pump or motor is installed on the top of the positioning beams. The assembly seat is fixedly installed to the bottom of the water ring vacuum pump or motor by bolts. The assembly seat includes a support component fixedly installed to the bottom of the water ring vacuum pump or motor. An adjustment component is provided inside the support component, and a positioning block is provided at the bottom of the support component. Due to the assembly seat, and with the cooperation of the positioning slots, this utility model allows workers to easily remove the water ring vacuum pump or motor from the channel steel base frame, and also facilitates their installation back onto the channel steel base frame. This avoids the inconvenience of frequently disassembling and reassembling bolts during maintenance, effectively improving the efficiency of daily maintenance.
[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although the mounting base, with the cooperation of the positioning slot, makes it easy for workers to remove components such as water ring vacuum pumps or motors from the channel steel base frame, and also makes it easy to install them onto the channel steel base frame, avoiding the inconvenience of frequently disassembling and reassembling bolts during maintenance and effectively improving the efficiency of daily maintenance, the vacuum pumps and motors have a certain weight, making it time-consuming and laborious to disassemble and lift them from the channel steel base frame, thus reducing the efficiency of maintenance of vacuum pumps and motors. Utility Model Content
[0005] The purpose of this invention is to address the problem in the existing technology that, although the mounting base, with the cooperation of the positioning groove, allows workers to easily remove components such as water ring vacuum pumps or motors from the channel steel base frame and also facilitates their installation on the channel steel base frame, avoiding the inconvenience of frequent bolt removal and installation during maintenance and effectively improving the efficiency of daily maintenance, the vacuum pumps and motors, due to their considerable weight, are time-consuming and laborious to disassemble and lift from the channel steel base frame, thus reducing the efficiency of maintenance of vacuum pumps and motors.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an air-cooled dry vacuum pump, comprising: a base plate, on which a motor and an air-cooled dry vacuum pump body are disposed, and further comprising:
[0007] A chute is equidistantly formed on the top of the base plate. A mounting plate is fixedly connected to the bottom of the motor and the air-cooled dry vacuum pump body. Multiple grooves are equidistantly formed on the bottom of the mounting plate. Two rotating rods are symmetrically rotatably connected to opposite sides of the inner wall of the groove. Rollers are fixedly connected to the outer surface of the rotating rods. The outer surface of the rollers is slidably connected to the inside of the chute.
[0008] Preferably, a connecting strip is fixedly connected to each opposite side of the mounting plate, and two square grooves are symmetrically opened on one side of each connecting strip. A round rod is fixedly connected to the opposite side of the inner wall of the square groove, and a limit block is rotatably connected to the outer surface of the round rod.
[0009] Preferably, two torsion springs are symmetrically arranged on the outer surface of the round rod. One end of each torsion spring is fixedly connected to the opposite side of the limiting block, and the other end of each torsion spring is fixedly connected to the opposite side of the inner wall of the square groove.
[0010] Preferably, a fixing plate is fixedly connected to each of the four corners of the top of the base plate, and a screw is threadedly connected to one side of the fixing plate.
[0011] Preferably, a limiting hole is provided on one side of the limiting block, and the outer surface of the screw is slidably connected to the inside of the limiting hole.
[0012] Preferably, the top of the base plate is provided with a plurality of strip grooves at equal intervals, and the top of the mounting plate is provided with a plurality of strip grooves at equal intervals.
[0013] Preferably, the top of the mounting plate is symmetrically fixed with two handles.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. This utility model allows the motor and air-cooled dry vacuum pump body to be easily removed from the base plate by holding the handle and pulling the mounting plate to one side. The mounting plate and connecting strip move to one side with the cooperation of the rotating rod, rollers, and sliding groove. A transport vehicle is placed on the side of the base plate, allowing the mounting plate and connecting strip to slide onto the vehicle. The transport vehicle facilitates the convenient transport of the motor and air-cooled dry vacuum pump body to the location requiring maintenance. This process is time-saving and labor-saving, thereby improving the efficiency of maintenance of components such as the motor and air-cooled dry vacuum pump body.
[0016] 2. This utility model, with the cooperation of rollers, allows the rollers to roll into the interior of the sliding groove, enabling the mounting plate to move onto the top of the base plate. Then, by hand, the limiting block is pulled outwards, causing it to rotate around the outer surface of the round rod and exit from the interior of the square groove. Simultaneously, the torsion spring twists, making the limiting block fit tightly against the fixing plate. Then, by hand, the screw is turned to insert into the limiting hole, limiting the limiting block and thus restricting the connecting strip and mounting plate. Conversely, the restriction on the connecting strip and mounting plate can be easily released. This allows for easy installation and fixing of the motor and the air-cooled dry vacuum pump body, simplifying the operation and improving the efficiency of installing or disassembling the motor and the air-cooled dry vacuum pump body.

Detailed Implementation
[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Examples, such as Figure 1-4 As shown, this utility model provides an air-cooled dry vacuum pump, including: a base plate 1, a motor 201 and an air-cooled dry vacuum pump body 202 are arranged on the top of the base plate 1, and also includes: a sliding groove 101, which is equidistantly opened on the top of the base plate 1. A mounting plate 2 is fixedly connected to the bottom of the motor 201 and the air-cooled dry vacuum pump body 202. A plurality of grooves 205 are equidistantly opened on the bottom of the mounting plate 2. Two rotating rods 206 are symmetrically rotatably connected to opposite sides of the inner wall of the grooves 205. Rollers 207 are fixedly connected to the outer surface of the rotating rods 206. The outer surface of the rollers 207 is slidably connected to the inside of the sliding groove 101 and the outer surface of the rollers 207 is slidably connected to the inside of the grooves 205.
[0026] Furthermore, such as Figure 1-4 As shown, connecting strips 3 are fixedly connected to opposite sides of the mounting plate 2. Two square grooves 301 are symmetrically opened on one side of each connecting strip 3. A round rod 302 is fixedly connected to the opposite side of the inner wall of the square groove 301. A limit block 304 is rotatably connected to the outer surface of the round rod 302. With the above arrangement, the limit block 304 can rotate around the outer surface of the round rod 302.
[0027] Furthermore, such as Figure 1-4 As shown, two torsion springs 303 are symmetrically arranged on the outer surface of the round rod 302. One end of each torsion spring 303 is fixedly connected to the opposite side of the limiting block 304, and the other end of each torsion spring 303 is fixedly connected to the opposite side of the inner wall of the square groove 301. Under the restoring force of the torsion springs 303, the limiting block 304 can rotate around the outer surface of the round rod 302 towards the inside of the square groove 301.
[0028] Furthermore, such as Figure 1-4 As shown, a fixing plate 102 is fixedly connected to each of the four corners of the top of the base plate 1. A screw 103 is threadedly connected to one side of the fixing plate 102. With the cooperation of the screw connection between the fixing plate 102 and the screw 103, when the screw 103 is rotated, the screw 103 can be moved to one side. When it is not rotated, the screw 103 can be kept in a fixed state.
[0029] Furthermore, such as Figure 1-4 As shown, a limiting hole 305 is provided on one side of the limiting block 304, and the outer surface of the screw 103 is slidably connected to the inside of the limiting hole 305. By inserting the screw 103 into the inside of the limiting hole 305, the limiting block 304 is limited.
[0030] Furthermore, such as Figure 1-4 As shown, the top of the base plate 1 is provided with multiple strip grooves 104 at equal intervals, and the top of the mounting plate 2 is provided with multiple strip grooves 204 at equal intervals. By setting the strip grooves 104 and 204, the weight of the base plate 1 and the mounting plate 2 can be reduced, and a certain heat dissipation effect can be achieved.
[0031] Furthermore, such as Figure 1-4 As shown, two handles 203 are symmetrically fixedly connected to the top of the mounting plate 2.
[0032] Working principle: When it is necessary to disassemble the motor 201 and the air-cooled dry vacuum pump body 202 for maintenance, the screw 103 is turned by hand to disengage it from the inside of the limiting hole 305, releasing the limiting block 304. The torsion spring 303 in the figure is in a torsion state. At this time, under the restoring force of the torsion spring 303, the limiting block 304 can be rotated around the round rod 302 into the inside of the square groove 301, releasing the relatively fixed state of the connecting strip 3 and the mounting plate 2. Then, by holding the screw 103 by hand... Hold handle 203 and pull mounting plate 2 to one side. This allows mounting plate 2 and connecting strip 3 to move to one side with the cooperation of rotating rod 206, roller 207, and slide groove 101. By placing a transport vehicle on the side of base plate 1, mounting plate 2 and connecting strip 3 can slide onto the transport vehicle. This allows motor 201 and air-cooled dry vacuum pump body 202 to be easily removed from base plate 1. With the help of the transport vehicle, motor 201 and air-cooled dry vacuum pump body 202 can be easily transported to the required location. In areas requiring inspection and maintenance, this process is relatively time-saving and labor-saving, thereby improving the efficiency of inspection and maintenance of components such as the motor 201 and the air-cooled dry vacuum pump body 202. When the inspection and maintenance is completed, with the cooperation of the roller 207, the roller 207 is rolled into the interior of the slide groove 101, which allows the mounting plate 2 to move onto the top of the bottom plate 1. Then, by hand, the limiting block 304 is pulled outward, causing it to rotate out of the interior of the square groove 301 around the outer surface of the round rod 302. Simultaneously, the torsion spring 303 is twisted, causing the limiting block to rotate out of the interior of the square groove 301. The positioning block 304 is tightly attached to the fixing plate 102. Then, by manually rotating the screw 103, it is inserted into the limiting hole 305 to limit the positioning block 304, thereby limiting the connecting strip 3 and the mounting plate 2. Conversely, the limiting of the connecting strip 3 and the mounting plate 2 can be easily released. This makes it easy to install and fix the motor 201 and the air-cooled dry vacuum pump body 202. The operation is relatively simple, thereby improving the efficiency of installing or disassembling the motor 201 and the air-cooled dry vacuum pump body 202.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
