Abstract
The utility model provides a vacuum pump. When a prior vacuum pump is used, a main factor which restricts the service life of the vacuum pump is that a main part of the vacuum pump is easy to abrade, especially in environments with plenty of particles and dust, due to the fact that plenty of dust is sucked in the vacuum pump and stays at a transmission position, abrasion of the vacuum pump is accelerated, and the service life of the vacuum pump is reduced greatly. The vacuum pump comprises a machine shell (1), wherein an impeller (2) is installed in the machine shell (1), the machine shell (1) is connected with an air inlet pipe (3) and an air outlet pipe (4), the impeller (2) is connected with a driving motor (5), and a filter device (6) is arranged at the position of the air inlet pipe (3). According to the vacuum pump, cleanness of the transmission part of the vacuum pump is kept, and the service life the vacuum pump is effectively prolonged.
Description
Technical field
The utility model relates to a kind of vacuum pump, belongs to the chemical machinery technical field.
Background technique
Vacuum pump is to utilize machinery, physics, chemistry or physicochemical method that quilt is taken out that container is bled and the device or the equipment that obtain vacuum is widely used in the fields such as pigment chemical industry, tile machinery, Cryo Equipment, papermaking equipment, medication chemistry, food machinery, industrial furnace, electron trade, vacuum equipment, chemical fertilizer, metallurgy, oil, mine, ground processing.Vacuum pump can be divided into two types basically, i.e. gas transport pump and gas capture pump.Vacuum pump in use, its major component is worn and torn easily, it is the topmost reason of restriction service life of vacuum pump, particularly in the many environment of some particle dusts, because a large amount of dust is inhaled in the vacuum pump, rest on the transmission position, more accelerated the wearing and tearing of vacuum pump, greatly reduce the working life of vacuum pump.
The model utility content
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of vacuum pump, can effectively avoid vacuum pump to be inhaled into the dust wearing and tearing in the environment that high particle dust exists, thereby prolong the working life of vacuum pump.
Above-mentioned purpose is achieved through the following technical solutions:
Vacuum pump comprises casing, and impeller is installed in described casing the inside, and described casing connects respectively suction tude and outlet pipe, and described impeller connects drive motor, and filtrating equipment is installed at described suction tude place.
Described vacuum pump, described filtrating equipment comprises two-layer filter screen, is positioned at the aperture of outer field described filter screen greater than the aperture of the filter screen that is positioned at nexine.
Described vacuum pump, described casing bottom arranges shock bracket.
Beneficial effect:
1. the utility model is installed filtrating equipment at the suction port place of existing vacuum pump, can at first filter out the particle dust that exists in the vacuum pump environment of living in, avoid a large amount of particle dusts to be inhaled into the wearing and tearing of the transmission part that causes behind the vacuum pump, the cleaning that keeps vacuum pump transmission position can effectively prolong working life of vacuum pump.
2. the utility model adopts two-layer strainer filtering, and the outer filter aperture is larger, filters out first the impurity of larger granularity, inner filter screen carries out secondary filter again, reduces the burden of individual layer filter screen, avoids filter screen blocked fast, reduce the number of times of changing filter screen, save manpower.
3. the utility model is provided with shock bracket in the casing bottom, can reduce vibrations, builds a preferably working environment, reduces simultaneously vibrations and is beneficial to less noise pollution.
