Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of diaphragm pumps, specifically to a suction pipe for a material-suction diaphragm pump. Background Technology
[0002] A diaphragm pump uses a diaphragm to separate the pumped liquid from the piston and cylinder, thus protecting the piston and cylinder. The left side of the diaphragm, which is in contact with the liquid, is made of corrosion-resistant material or coated with a corrosion-resistant substance; the right side of the diaphragm is filled with water or oil.
[0003] However, when the diaphragm pump draws powder out of the powder tank, the powder will enter the suction pipe. Because the powder accumulation can easily block the suction pipe, the diaphragm pump may be damaged due to the powder accumulation causing the pipe to become sealed. Utility Model Content
[0004] This utility model proposes a suction pipe for a diaphragm pump, which can prevent powder inside the suction pipe from clogging by setting a movable component and opening a second hollow groove at the outer end of the suction pipe.
[0005] Therefore, the technical solution adopted is as follows:
[0006] A suction pipe for a diaphragm pump is disclosed, wherein the suction pipe absorbs powder through the diaphragm pump. The pipe includes two fixed rings fitted onto the suction pipe at a certain distance from each other. Each of the two fixed rings has a groove on its opposite side, the groove being a circular structure surrounding the suction pipe. A movable rod is located between the two fixed rings, and a fixing nut with matching thread is fitted onto the movable rod. Both ends of the movable rod are inserted into the grooves on both sides and can be locked to the fixed rings by the fixing nuts. A movable tube is fitted onto the suction pipe between the two fixed rings, the movable tube having a first hollow groove and a second hollow groove corresponding to the first hollow groove. The movable tube is fixedly connected to the movable rod by a support rod.
[0007] A further technical solution is that the diaphragm pump also includes a base and a pump body, the pump body being fixedly connected to the upper end of the base, and the suction pipe being fixedly connected to the top of the pump body.
[0008] A further technical solution includes a linkage component, which comprises a fixed gear fixed to the end of the suction pipe, a planetary gear meshing with the fixed gear, and a gear ring meshing with the planetary gear on the outermost side. A fixed rod is fixed on the planetary gear, and a baffle is fixed to the other end of the fixed rod. The gear ring and the movable rod are fixed together by a connecting rod. When the movable rod rotates to close the second hollow groove, the gear ring rotates accordingly to close the end of the suction pipe with the baffle.
[0009] Further technical solutions are that the connecting rod is in a U-shaped structure.
[0010] Further technical solutions are that the diameter of the baffle is the same as that of the material suction pipeline, and the inner side of the baffle is flush with the outer side of the material suction pipeline.
[0011] The working principle and beneficial effects of the present application are as follows: the material suction pipeline of the material suction diaphragm pump provided by the present application is provided with a movable assembly, a second hollow groove is formed at the outer end of the material suction pipeline, so that the powder inside the material suction pipeline cannot be blocked inside the material suction pipeline, and the movable rod is rotated to drive the movable pipe to rotate through the support rod, so as to change the position of the first hollow groove, so that the second hollow groove and the first hollow groove are staggered, so as to close the second hollow groove, so that dust and dirt from the outside cannot enter the inside of the material suction pipeline when the material suction pipeline is not in use.
