Horizontal foam pump capable of preventing backflow

Abstract

The utility model relates to the technical field of horizontal foam pumps, in particular to an anti-backflow horizontal foam pump which comprises a pump body. When the horizontal foam pump is started, fluid passes through the pump body to smash large foam, the fluid enters the water outlet pipe, the baffle moves upwards under the action of impact force, the spring is compressed, the fluid flows through the leakage plate to drive the blades to rotate, and then the transverse rod is driven to rotate through transmission of the first bevel gear and the second bevel gear. When the horizontal foam pump is shut down, the baffle without extrusion force resets under the action of self-elasticity of the spring, so that the pump body is prevented from being damaged by fluid, the fluid can pass through the paddle to generate power to pump the defoaming agent, and the defoaming agent is pumped into the water outlet pipe. And meanwhile, the situation that the pump body is damaged due to the fact that the residual fluid in the pipe flows back after shutdown is avoided, and the service life of the pump body is prolonged.

Description

Technical Field

[0001] The utility model relates to the technical field of horizontal foam pumps, in particular to a horizontal foam pump capable of preventing backflow. Background Art

[0002] Extracting minerals from ores generally requires crushing and grinding the ores. For complex ores, in order to maximize the recovery of minerals, they need to be ground into fine particles. The fine particles of mineral ores are fully mixed with water to form a fluid, and the mineral particles float to the surface in the form of mineral foam, while the waste rock sinks. The mineral foam produced by the flotation tank contains fine particles, and the bubbles are very finely dispersed. To move the mineral foam from one flotation tank to another, and then to the next process, it is necessary to pump the fluid. Generally, a horizontal foam pump is selected. The blades of the horizontal foam pump can effectively break up the larger mineral foam.

[0003] However, some horizontal foam pumps nowadays are not convenient for removing smaller foams and have low practicality. At the same time, the water outlet of the horizontal foam pump is at the top, and the residual fluid in the pipe will flow back after shutdown, causing damage to the pump body and reducing its service life. Therefore, we propose a horizontal foam pump with anti-backflow function to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a horizontal foam pump capable of preventing backflow, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a horizontal foam pump capable of preventing backflow, comprising a pump body, the pump body being provided with a water inlet and a water outlet, a water outlet pipe being fixed to the top of the water outlet through a flange, a defoaming agent tank and a circular tube being fixedly connected to the left side of the water outlet pipe, a vertical rod being provided inside the water outlet pipe, a paddle being fixedly connected to the outer side of the vertical rod, a first bevel gear being fixedly connected to the top of the vertical rod, a second bevel gear being meshed with the outer side of the first bevel gear, a cross rod being fixedly connected to the left side of the second bevel gear, the left end of the cross rod extending into the circular tube, the water outlet pipe being rotatably sleeved on the outer side of the cross rod, a reciprocating screw being fixedly connected to the left end of the cross rod, the left end of the reciprocating screw being rotatably connected to the circular tube, and a slide being provided on the outer threaded sleeve of the reciprocating screw.

[0006] Further preferably, the slide plate is slidably connected to the inside of the round tube, and a feed pipe is connected between the round tube and the defoaming agent tank body.

[0007] Further preferably, the right side of the circular tube is connected to a discharge pipe, and the discharge pipe extends into the water outlet pipe.

[0008] Further preferably, a baffle is slidably connected to the interior of the water outlet pipe, and a leaking plate is fixedly connected to the interior of the water outlet pipe.

[0010] Further preferably, the top end of the second round rod is fixedly connected to the bottom of the leaking plate, and the vertical rod is rotatably connected to the top of the leaking plate.

[0011] Further preferably, a spring is fixedly connected between the second round rod and the baffle, and the spring is movably sleeved on the outside of the first round rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when the horizontal foam pump of the utility model is started, the water inlet draws the fluid into the water outlet and discharges it, and the larger foam is broken through the pump body, and the fluid enters the water outlet pipe. Under the action of the impact force, the baffle moves upward, the spring is compressed, and the fluid flows through the leak plate to drive the blade to rotate, and then drives the cross bar to rotate through the transmission of the first bevel gear and the second bevel gear, and the cross bar drives the reciprocating screw to rotate, thereby driving the slide plate to move reciprocatingly and laterally, and the defoaming agent is pumped into the water outlet pipe. When the horizontal foam pump is shut down, the baffle that loses the extrusion force is reset under the action of the spring's own elastic force, thereby avoiding the fluid from damaging the pump body, so that the defoaming agent can be pumped in by the fluid passing through the blade to be fully mixed with the fluid to remove smaller foams, and at the same time, the residual fluid in the pipe after shutdown is avoided from flowing back to damage the pump body, thereby improving its service life.
