Description

Technical Field

[0001] This utility model relates to the field of powder pumping technology, and in particular to a powder pumping device with a quick-connect structure. Background Technology

[0002] A powder pump, also known as a powder conveying pump, is a device specifically designed for conveying powdery materials. It utilizes fluid dynamics principles, such as the Venturi principle, to attract and transport powdery materials by creating a pressure difference. Powder pumps are widely used in various industries, including food, medical, pharmaceutical, and chemical, for conveying dry powders such as pigments, plasticizers, and pharmaceutical raw materials. Their simple structure offers greater ease of use and better economic benefits compared to traditional, complex powder conveying systems. Driven by a motor, the powder pump efficiently and cleanly transports materials through pipelines, meeting diverse production needs.

[0003] In existing powder pumps, the inlet pipe at the rear of the pump is connected to a blower, and the outlet pipe at the front of the pump is connected to the powder conveying pipe via a flange. However, the two sets of flanges often require multiple bolts and nuts to be screwed together, making the assembly and use of the outlet pipe and the powder conveying pipe cumbersome and inconvenient for the use and maintenance of the pump. Therefore, we propose a powder pump with a quick-connect structure. Utility Model Content

[0004] The main objective of this invention is to provide a powder pump with a quick-connect structure. A sleeve head is installed at the powder outlet pipe of the powder pump body, and a connecting head is fitted at the sleeve head. After the sleeve head is assembled outside the powder outlet pipe, the connecting head can be assembled outside the powder conveying pipe. The connecting head can then be screwed into the sleeve head to cover the flanges of both the powder conveying pipe and the powder outlet pipe. Half-connector A and half-connector B form an external threaded connector that fits over the flanges of both the powder conveying pipe and the powder outlet pipe. This allows for quick connection of the powder outlet pipe of the powder pump body to an external powder conveying pipe. Compared to the multiple bolts and nuts used in flange connections, the screwing connection of the sleeve head and the connecting head enables rapid connection or disassembly of the powder outlet pipe to the external powder conveying pipe, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] By adopting the above technical solution, after the abutment ring is fitted outside the powder outlet pipe, the T-shaped mating plate A between the half-cover pipe A and the half-cover pipe B can connect the abutment ring to the flange at one end of the powder outlet pipe.

[0013] Furthermore, notches are provided at the ring bodies of the inner ring A and the inner ring B;

[0014] By adopting the above technical solution, the ring bodies of inner ring A and inner ring B can be opened from the notch, so that they can be respectively fitted onto the powder outlet pipe and the powder conveying pipe.

[0015] Furthermore, the bolts of the hexagonal socket screws are screwed into the small cavities of the connecting holes A and B, and the heads of the hexagonal socket screws are engaged in the large cavities of the connecting holes A and B.
