Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pump impeller cleaning auxiliary devices, in particular to a vacuum pump impeller cleaning device. Background Art

[0002] In the alumina production industry, an important factor restricting the production capacity and efficiency of alumina production equipment is the scarring in each link of the production process. The scarring of alumina in each link of the production process will have a great impact on the production process and procedures of alumina. At present, there is no completely effective method to prevent the formation of alumina scarring. During the operation of the vacuum pump, the main component of aluminum hydroxide will gradually adhere to and deposit on the impeller with the airflow to form scars, causing the dynamic balance of the impeller to be destroyed, thereby increasing the energy consumption of the equipment and even damaging the equipment.

[0003] The existing vacuum pump impeller cleaning method is that the staff cleans the impeller with a handheld cleaning auxiliary tool, which has the problems of low cleaning efficiency and poor cleaning effect. Therefore, it is particularly important to design a vacuum pump impeller cleaning device to solve the above technical problems. Utility Model Content

[0004] The utility model aims to solve the problem that the existing vacuum pump impeller cleaning method in the prior art requires staff to clean the impeller with handheld cleaning auxiliary tools, resulting in low cleaning efficiency and poor cleaning effect, and proposes a vacuum pump impeller cleaning device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vacuum pump impeller cleaning device, comprising a pump body, an impeller is fixedly connected to the pump body, a spray device is installed on the pump body, the spray device comprises a ball valve, an adapter is connected to the bottom of the ball valve, the top of the ball valve is connected to a water pipe, the adapter is a four-way valve, and hoses are fixedly connected on both sides and below the adapter.

[0006] Preferably, the software on both sides of the adapter is an arc-shaped structure, and the end position of the hose is connected to a nozzle through an elbow.

[0007] Preferably, adjacent nozzles are evenly distributed around the impeller in the circumferential direction, and the nozzles are facing the impeller.

[0008] Preferably, the water spray inclination angle of the nozzle is 15 degrees, and the nozzle is fixedly connected to the pump body through a flange.

In the utility model, during use, the spray device is movably and detachably connected to the pump body, and the adjacent nozzles are tilted at an angle of 15 degrees, so that the nozzles in the spray device achieve the optimal spray cleaning effect. Compared with the conventional cleaning method in which the staff holds a cleaning auxiliary tool, the technical solution adopted by the utility model cleans the impeller with a nozzle tilted at 15 degrees. The overall structure is compact and can be directly installed on the pump body, which is easy for the staff to install and maintain. This solves the problem of low cleaning efficiency and poor cleaning effect in the existing vacuum pump impeller cleaning method in which the staff holds a cleaning auxiliary tool to clean the impeller.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] The utility model provides a vacuum pump impeller cleaning device, comprising a pump body 1, wherein an impeller 2 is fixedly connected to the pump body 1, a spray device 3 is installed on the pump body 1, and the spray device 3 comprises a ball valve 301, a converter 302 is connected to the bottom of the ball valve 301, a water pipe 303 is connected to the top of the ball valve 301, the converter 302 is a four-way valve, and hoses 304 are fixedly connected to the two sides and the bottom of the converter 302, the software on both sides of the converter 302 is an arc structure, and nozzles 306 are connected to the end positions of the hose 304 through elbows 305, and the adjacent nozzles 306 are uniformly distributed around the impeller 2 in the circumferential direction, and the nozzles 306 are facing the impeller 2 to improve the spray cleaning effect of the nozzles 306.

[0018] When the vacuum pump impeller 2 cleaning device is in use, the water connecting pipe 303 at the position above the ball valve 301 is connected to the external water valve, and the high-pressure hot water (or cleaning liquid) is divided to the three nozzles 306 through the adapter 302. The spray device 3 is detachably connected to the pump body 1 according to the angle, so that the three nozzles 306 can spray to the entire impeller 2, thereby achieving the purpose of cleaning the impeller 2. The angle and position of the spray device 3 are set, and the spray device 3 is detachable. During later maintenance, it can be removed and replaced with a new spray port and spray device 3. By making the spray device 3 detachably connected to the pump body 1 as a whole, and the adjacent inclination angles of the nozzles 306 are 15 degrees, the nozzles 306 in the spray device 3 achieve the optimal spray cleaning effect. Compared with the conventional cleaning method in which the staff holds a cleaning auxiliary tool, the technical solution adopted by the utility model cleans the impeller 2 with the nozzle 306 set at an inclination of 15 degrees. The overall structure is compact and directly installed on the pump body 1, which is easy for the staff to install and maintain.

[0019] like Figure 1 As shown, the water spraying inclination angle of the nozzle 306 is 15 degrees. The nozzle 306 is fixedly connected to the pump body 1 through the flange 4. The pressure in the nozzle 306 is 0.3~1MPa.

[0020] The effect achieved by the entire embodiment 1 is that, during use, the water spraying inclination angle through the nozzle 306 is 15 degrees, so that the pressurized water spray directly acts on the impeller 2, achieving the effect of cleaning the impeller 2.

[0021] Working principle: The water inlet pipe above the ball valve is connected to an external water valve. High-pressure hot water (or cleaning fluid) is diverted to three nozzles through the adapter. The spray device is detachably connected to the pump body according to the angle, so that the three nozzles can spray to the entire impeller, thereby achieving the purpose of cleaning the impeller. The spray device is set at an angle and position, and the spray device is detachable. During later maintenance, it can be removed and replaced with a new spray port and spray device.
