Description

Technical Field

[0001] The utility model belongs to the technical field of an esterification EG pump inlet filter, and in particular relates to an esterification EG pump inlet filter with good filtering effect. Background Art

[0002] The esterification process tower is an important equipment for separating esterified EG and esterified water. Since the gas phase equilibrium line of the esterification EG tank is inserted into the tank low, the operating condition of the process tower is affected, causing the tower plate fasteners to fall off and enter the esterification EG tank along the esterification EG reflux pipeline. The tower plate fasteners will enter the esterification EG pump together with the EG, causing the esterification EG pump impeller and pump casing to wear, and the pump body to be damaged, causing the esterification EG pump to be unable to operate normally, affecting normal process production. In view of the above phenomenon, an esterification EG pump inlet filter has been derived to complete the filtering of impurities inside the fluid and tower plate fasteners.

[0003] However, the existing inlet filter of the esterified EG pump also has certain shortcomings. The existing inlet filter of the esterified EG pump simply uses a filter to filter the fluid. Due to the influence of factors such as the adhesion characteristics of impurities, long-term use will cause the filter to be blocked, resulting in poor circulation effect of the filter. Summary of the invention

[0004] The utility model aims to provide an esterification EG pump inlet filter with good filtering effect, which solves the problem that the existing esterification EG pump inlet filters mostly simply use filter screens to filter the fluid, and due to the influence of factors such as the adhesion characteristics of impurities, long-term use may cause clogging of the filter screen, resulting in poor circulation effect of the filter screen.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an esterification EG pump inlet filter with good filtering effect, comprising a process tower, an esterification EG tank, a basket filter and an esterification EG pump, the process tower and the esterification EG tank are connected by a reflux pipeline, the esterification EG tank and the basket filter are connected by a reflux pipeline, the basket filter and the esterification EG pump are connected by a reflux pipeline, the esterification EG pump and the process tower are connected by a reflux pipeline, the upper end of the basket filter contacts with a shell cover, the lower end of the shell cover is fixedly connected with an insert block, the insert block is slidably connected to the basket filter, the inside of the basket filter is slidably connected with an insert rod, the insert rod is slidably connected to the insert block, the outer side of the insert rod is fixedly sleeved with a movable disk, the movable disk is slidably connected to the basket filter, and a filtering mechanism is arranged inside the basket filter.

[0006] The principle of the utility model is that through the setting of the filter screen, the fluid inside the return pipeline can be filtered for impurities, and the waterproof motor is started to drive the output shaft to rotate, so as to drive the filter screen to rotate, and then drive the rotating disk to rotate along the inner wall of the basket filter, so that the bristles slide along the surface of the filter screen, and the impurities attached to the filter screen are cleaned to avoid the clogging problem of the filter screen. In this process, the waterproof motor drives the output shaft to rotate, so as to drive the moving cylinder to rotate, and then drive the guide block to rotate, and finally drive the limiting ball to slide along the inner wall of the limiting ring groove, and the output shaft of the waterproof motor is rotationally limited to avoid the problem of shaking of the output shaft of the waterproof motor, so as to ensure the stable rotation of the filter screen. Under the deformation action of the second spring, the guide block can be pushed to drive the limiting ball to always contact with the inner wall of the limiting ring groove to ensure the limiting effect of the limiting ball.

[0007] By pulling the rod to move away from the basket filter, the movable plate is driven to move. Once the spring is deformed, the rod is finally separated from the plug block. Then the shell cover is pulled upward to drive the plug block to separate from the basket filter. The shell cover is quickly removed, making it easier for operators to clean impurities attached to the filter screen.

[0008] The beneficial effects of the utility model are as follows: the scheme can filter out impurities from the fluid inside the return pipeline through the setting of the filter screen, and the filter screen can be driven to rotate by the driving action of the waterproof motor. Under the action of the bristles, impurities attached to the filter screen and impurities such as the tower plate fixing parts can be cleaned to avoid the blockage problem of the filter screen to ensure the normal circulation of the filter screen. Under the action of the spring 2, the guide block, the limit ball, the limit ring groove and other structures, the output shaft of the waterproof motor can be rotationally limited to avoid the shaking problem of the output shaft to ensure the stable rotation of the filter screen. By pulling the plug rod to move away from the basket filter, the movable disk can be driven to move. When the spring is deformed, the plug rod will eventually be separated from the plug block, and the shell cover can be pulled away from the basket filter, so that the operator can quickly remove the shell cover, which is convenient for subsequent cleaning of impurities and the like.

[0009] Furthermore, a spring 1 is welded to the end face of the movable disk close to the plug block, and the other end of the spring 1 is welded to the basket filter. Through the provision of the spring 1, the movable disk can be connected for use.

Through the setting of the filter, impurities in the fluid inside the return pipeline can be filtered out. The waterproof motor is started to drive the output shaft to rotate, so as to drive the filter to rotate, and then drive the rotating disk to rotate along the inner wall of the basket filter, so that the bristles slide along the surface of the filter to clean the impurities attached to the filter to avoid clogging of the filter. During this process, the waterproof motor drives the output shaft to rotate, so as to drive the moving cylinder to rotate, and then drive the guide block to rotate, and finally drive the limiting ball to slide along the inner wall of the limiting ring groove to limit the rotation of the output shaft of the waterproof motor to avoid the problem of shaking of the output shaft of the waterproof motor, so as to ensure the stable rotation of the filter. Under the deformation action of the second spring, the guide block can be pushed to drive the limiting ball to always contact the inner wall of the limiting ring groove to ensure the limiting effect of the limiting ball.

[0012] Furthermore, the filter screen is circular in shape as a whole and is woven from stainless steel wires. Impurities in the fluid can be filtered out by setting the filter screen, and the stainless steel wire material has good durability.
