Description

Technical Field

[0001] The utility model relates to the field of injectors, in particular to a solid-liquid injector. Background Art

[0002] At present, injectors are extremely widely used, such as powder transfer or mud movement. In the prior art, an injector generally has an inlet and an outlet. Usually, a machine with a large suction force is installed at the inlet to suck powder or mud into the injector, and then it is ejected from the outlet of the injector to transfer the powder or mud. However, the combination of such an injector in the prior art with a machine having a large suction force makes its structure complex, with high energy consumption, and poor injection effect, that is, poor transfer effect of materials or mud. Summary of the Invention

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a solid-liquid injector.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A solid-liquid injector includes a suction pipeline, a power connection valve, and a discharge pipeline. Among them, the power connection valve has a first power inlet and a second power inlet. The suction pipeline is inserted into the power connection valve, and the suction pipeline has a first inlet and a first outlet, and the first inlet and the first outlet are connected. The discharge pipeline is respectively connected to the power connection valve and the first outlet of the suction pipeline, so that the power gas or power liquid entering from the first power inlet and the second power inlet of the power connection valve flows into the discharge pipeline, and the liquid, gas or solid-liquid mixture to be transferred is sucked into the suction pipeline and discharged from the discharge pipeline.

[0005] Further, it further includes a nozzle. One end of the nozzle is connected to the power connection valve, the other end of the nozzle is connected to the discharge pipeline, and the nozzle 3 connects the power connection valve and the discharge pipeline.

[0006] Further, the nozzle includes a housing and a central column. The central column has a communication through-hole that penetrates the central column. An annular cavity is formed between the housing and the central column. When the nozzle is connected to the power connection valve, both the first power inlet and the second power inlet are connected to the annular cavity; when the nozzle is connected to the discharge pipeline, the annular cavity of the nozzle is connected to the discharge pipeline; the suction pipeline is clamped together with the nozzle, so that the first outlet of the suction pipeline is docked and connected to the communication through-hole.

[0007] Further, the annular cavity is a conical annular cavity, and the cross-section of the annular cavity near the power connection valve is larger than the cross-section of the annular cavity near the discharge pipe.

[0008] Further, the communication through-hole is a conical through-hole, and the cross-section of the communication through-hole near the suction pipe is larger than the cross-section of the communication through-hole near the discharge pipe.

[0009] Further, the power connection valve includes a first interface, a second interface, a third interface, and a fourth interface. The first interface has a first power inlet, the second interface has a second power inlet, and the fourth interface is fixedly connected to the nozzle.

[0010] Further, a fixed mounting plate is installed at the third interface of the power connection valve. The fixed mounting plate is hermetically connected to the third interface. A through-hole is provided on the fixed mounting plate. The suction pipe is inserted into the through-hole on the fixed mounting plate and extends into the power connection valve and extends to the fourth interface of the power connection valve. The suction pipe is hermetically connected to the fixed mounting plate.

[0011] Further, a first connecting plate is fixedly sleeved on the outer wall of the first inlet of the suction pipe, and a second connecting plate is fixedly sleeved on the outer wall of the second interface of the power connection valve.

[0012] Further, the discharge pipe has a second inlet and a second outlet, and the second inlet and the second outlet are communicated. When the nozzle is connected to the discharge pipe, the annular cavity is communicated with the second inlet, and the communication through-hole is communicated with the second inlet.

[0013] Further, a third connecting plate is fixedly sleeved on the outer wall of the second outlet of the discharge pipe.

[0014] The beneficial effect of the present application is as follows: The solid-liquid injector provided by the present application forms a high flow rate at the annular cavity of the nozzle. The high flow rate generates a negative pressure area. The pressure at the annular cavity and the pressure at the first outlet of the suction pipe form a pressure difference. Under the action of the pressure difference, the substance at the first inlet of the suction pipe is sucked into the suction pipe, then flows into the discharge pipe, and finally discharges from the second outlet of the discharge pipe. Based on this, one of the advantages of the present application is large suction and good cleaning effect; another advantage is simple structure and convenient assembly. Description of the Drawings
