Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slurry pumps, and more specifically, relates to a slurry pump which is convenient for dredging slurry. Background Art
[0002] Slurry pump belongs to centrifugal pump in terms of working principle. Conceptually, it refers to a machine that increases the energy of solid-liquid mixed medium by the action of centrifugal force, and converts electrical energy into kinetic energy and potential energy of the medium. It is mainly suitable for mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum industries. However, when selecting sand in seawater and dredging sand in rivers, slurry pumps are more likely to be called sand pumps or dredging pumps. Although the names are different, they can be generally called slurry pumps in terms of structural characteristics and pump performance principles.
[0003] Based on the above, the inventors have found the following problems: when the existing slurry pump is in use, when blockage occurs, the staff cannot accurately and quickly determine the cause of the blockage. During the dredging process, they generally dismantle the pump directly to inspect or clean the inside, but disassembly is more troublesome, resulting in a long downtime, which in turn affects production efficiency and indirectly increases the labor cost of the staff.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a slurry pump that is convenient for slurry drainage is provided, in order to achieve a purpose with greater practical value. Utility Model Content
[0005] The purpose and effect of the slurry pump of the utility model for facilitating slurry drainage are achieved by the following specific technical means:
[0006] A slurry pump for facilitating slurry drainage includes a support base, a drive motor mounted on the top of the support base, a slurry pump body connected to the output end of the drive motor, a feed pipe connected to one end of the slurry pump body, a small air pump connected to one side of the feed pipe, a first flange connected to one end of the feed pipe, a discharge pipe connected to one side of the slurry pump body, a water inlet connected to the surface of the discharge pipe, a second flange connected to one end of the discharge pipe, and a sealing cover mounted on one side of the second flange.
[0007] Furthermore, a plurality of sets of fixing bolts are installed on the surface of the slurry pump body.
[0008] Furthermore, a control panel is installed on the surface of the small air pump.
[0009] Furthermore, a first thread is provided on the surface of the first flange, and a second thread is provided on the surface of the second flange.
[0010] Furthermore, a handle is fixedly installed on the top of the sealing cover, a sealing gasket is installed inside the sealing cover, and a third thread is opened on the inner wall of the sealing cover.
[0011] Furthermore, the third thread engages with the first thread and the second thread.
[0012] Furthermore, the material of the slurry pump body is set to be high chromium alloy material.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] Under the action of the small air pump, when the discharge pressure of the slurry pump body is insufficient or no material is discharged, the staff can operate the small air pump to evacuate the inside through the control panel. When the value shows that the internal air pressure has not changed, it may be that there is a leak somewhere that is not sealed, which leads to insufficient discharge pressure or no material discharge. It can be quickly determined whether the discharge is caused by leakage. At the same time, this design can quickly determine the cause of the internal blockage of the slurry pump, improve the detection efficiency, and indirectly save the labor cost of the staff, greatly increasing practicality.
[0015] Through the cooperation between the sealing cover, the third thread, the first thread and the second thread, when the staff determines that the internal impeller is blocked, the sealing cover can be sealed by rotating the handle through the thread to seal the feed end of the slurry pump body, and water can be injected into the water inlet at the same time, and the pump body and pipeline can be flushed with water until the water flow is discharged regularly from the discharge end. The sand and gravel stuck inside can be punched and discharged, and the residual slurry inside can be cleaned conveniently. The operation steps are very simple, and some minor problems can be avoided by directly disassembling it, which indirectly brings convenience to the staff.
[0016] Through the design of high chromium alloy, it can be made to have extremely strong wear resistance, corrosion resistance and high temperature strength, and can be widely used in the treatment of waste slag with higher hardness and larger particles. BRIEF DESCRIPTION OF THE DRAWINGS
