Abstract
Description
Technical Field
[0001] The present application relates to the field of diaphragm pumps, and more specifically, to a diaphragm pump assembly. Background Art
[0002] The diaphragm pump is a new type of conveying machinery, which uses compressed air as the power source. It can pump out all kinds of corrosive liquids, liquids with particles and highly toxic liquids. The diaphragm pump uses a thin film to separate the liquid being transported from the piston and the pump cylinder, thereby protecting the piston and the pump cylinder. The left side of the diaphragm that contacts the liquid is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances; the right side of the diaphragm is filled with water or oil. The transmitted liquid often contains impurities. In order to ensure long-term and stable use, it needs to have a filtering function.
[0003] Some existing diaphragm pumps have a filter screen in the liquid inlet pipe. When the device is used for a long time, the filter screen may be clogged, thereby affecting the efficiency of subsequent liquid transmission and reducing the use effect of the device. Therefore, in order to solve the above problem, we propose a diaphragm pump assembly. Utility Model Content
[0004] In order to solve the above problems, the present application provides a diaphragm pump assembly, which adopts the following technical solutions:

[0006] A filter tube is connected to the end of the liquid inlet pipe, and an opening is provided on the side wall of the filter tube, an arc plate is hinged in the opening, a fixing component is provided between the arc plate and the filter tube, a filter plate is slidably installed in the filter tube, two symmetrically distributed blocks are fixedly installed on the side wall of the filter plate, a card groove matching the card block on the same side is provided on the inner side of the arc plate and the inner wall of the filter tube, a sealing gasket is provided on the outer side of the filter plate, and a cleaning component is provided on the side of the filter plate away from the liquid inlet pipe.
[0007] By adopting the above technical solution, when the equipment is used, the staff installs the pump body above the support plate through the support assembly, and then fixes it through the mounting block installed on the side wall of the base through the existing fasteners to fix the pump body. Then, the staff flips the arc plate to disengage the arc plate from the opening opened on the side wall of the filter tube. Then, the staff places the filter plate in the filter tube to engage the block installed on the side wall of the filter plate with the groove opened on the inner wall of the filter tube. Then, the staff flips the arc plate to engage the arc plate with the opening, and fixes the arc plate to the filter tube through the fixing assembly, thereby engaging the groove opened on the inner wall of the arc plate with the block installed on the side wall of the filter tube. The installed card block can be engaged to play the role of installing and fixing the filter plate, and a sealing gasket is provided on the outside of the filter plate. The squeezing of the arc plate and the filter tube is beneficial to improve the sealing of the installation between the filter plate and the filter tube. Vibration may be generated when the pump body is running. The setting of the shock-absorbing component between the support plate and the base plays a role of shock absorption and buffering. The operation of the pump body allows the liquid to enter the filter tube, and then enter the pump body through the liquid inlet pipe after being filtered through the filter plate, which helps to prevent impurities from entering the pump body and facilitates the subsequent continuous use of the pump body. The cleaning component can be driven to operate by the flow rate of the liquid to play a role of self-cleaning the filter plate, which is beneficial to maintain the filtering effect of the filter plate.
[0008] Furthermore, the support assembly includes two rings that are slidably sleeved on the side walls of the pump body, a support frame is fixedly installed between the two rings and the top of the support plate, the ring includes a second half ring that is fixedly installed on the top of the support frame, and a first half ring is provided above the two second half rings, first support blocks are fixedly installed on both sides of the first half ring and the second half ring, and the two first support blocks in the same group are screwed together and fixed by a first bolt and a first nut.
[0009] By adopting the above technical solution, the staff places the pump body inside the two second half rings, and then shines the first half ring on the side wall of the pump body to align and fit the first half ring with the second half ring, and then passes the first bolt through the two first support blocks of the same group and cooperates with the first nut to fix the two first support blocks, thereby fixing and splicing the first half ring and the second half ring of the same group, and then through the cooperation of the support plate, the support frame and the ring, it can support and stabilize the pump body.
[0010] Furthermore, two symmetrically distributed stabilizing rods are fixedly mounted on the bottom ends of the two first half rings, and stabilizing grooves matching the stabilizing rods in the same group are formed on the top ends of the two second half rings.
[0011] By adopting the above technical solution, when the first half ring and the second half ring of the same group are fitted together, the staff makes the stabilizing rod installed at the bottom end of the first half ring engage with the stabilizing groove opened on the side wall of the second half ring. Through the cooperation of the stabilizing rod and the stabilizing groove, the first half ring and the second half ring are positioned and fixed, which is convenient for the staff to install later.

[0013] By adopting the above technical solution, vibration may be generated when the pump body is running. The vibration force generated when the pump body is running is absorbed by the support spring and the shock-absorbing spring. Subsequently, the rebound force of the shock-absorbing spring and the support spring is offset by the shock absorber, which is conducive to maintaining the stability of the pump body during use. The shock absorber and the support assembly play a role in supporting the pump body.
[0014] Furthermore, the fixing assembly includes a second support block fixedly mounted on the arc plate and the side wall of the filter tube, the two second support blocks are screwed together and fixed by a second bolt and a second nut, the side wall of the arc plate is provided with a rubber pad, the bottom end of the arc plate is fixedly mounted with an insertion rod, and the top end of the opening is provided with a slot matching the insertion rod.

Subsequently, the staff passes the second bolt through the two second support blocks, and the cooperation of the second bolt and the second nut can fix the arc plate, and the side wall of the arc plate is provided with a rubber pad, which is beneficial to increase the sealing between the arc plate and the opening.
[0016] Furthermore, the cleaning assembly includes a mounting plate arranged in the filter tube, the bottom end of the mounting plate is fixedly sleeved with a support plate, the top end of the support plate is provided with two symmetrically distributed third bolts, the inner wall of the filter tube is provided with screw grooves matching the third bolts, the top and bottom ends of the mounting plate are fixedly installed with positioning rods, the inner wall of the arc plate and the inner wall of the filter tube are provided with positioning grooves matching the positioning rods, a rotating rod is rotatably installed on the side of the mounting plate away from the filter plate, a turbine blade is fixedly sleeved on the side wall of the rotating rod, the rotating rod passes through the mounting plate at one end close to the filter plate, and the rotating rod passes through the side wall of one end of the mounting plate and is fixedly installed with two symmetrically distributed brush plates.
