Device for preventing wax explosive from blocking pipeline

Technical Field

The utility model relates to the field of explosive production, in particular to a device capable of preventing materials from entering a discharge pipeline and preventing the materials from being accumulated to block the pipeline, which is suitable for equipment which needs to use a blocking mode to prevent the materials from blocking the pipeline, and particularly relates to a device for preventing certain wax-like explosive from blocking the pipeline.

Background

The method comprises the following steps of putting the molten waxy explosive into a dilution crystallization tank from a reaction kettle, crystallizing the molten waxy explosive under a pressure-air stirring state by filling a large amount of chilled water in the dilution crystallization tank, and then discharging crystallized materials from a discharge pipeline.

Before the pipeline device is prevented from being blocked by certain wax-like explosive by not installing, because of the reason of diluting the crystallization effect of the crystallization tank, the wax-like explosive which is not completely crystallized enters the feeding pipeline along with water flow, and the following problems can occur:

1. when the molten waxy explosive is put into the dilution crystallization tank from the reaction kettle, the incompletely crystallized granular explosive enters the discharge pipeline because the discharge pipe is low.

2. The specific gravity of the molten waxy explosive is larger than that of water, so that the material blocks a discharge pipeline and cannot be discharged, a discharge ball valve needs to be opened during blocking, a copper bar or a non-ignition material needs to be manually used for dredging, the friction and the impact of the explosive are caused, and potential safety hazards exist.

Through retrieval, no corresponding technical scheme exists in the prior art.

Disclosure of Invention

The utility model provides a device for preventing wax-like explosive from blocking a pipeline, which aims to solve the technical problem that the wax-like material enters a discharging pipeline without being completely crystallized to cause blockage of the discharging pipeline.

The utility model is realized by adopting the following technical scheme: a device for preventing wax-like explosive from blocking a pipeline comprises a vertically arranged transmission rod, wherein the bottom of the transmission rod is connected with an inserting plate for blocking a discharge pipe orifice of a discharge pipeline, the top of the transmission rod is connected with a drawing handle, and the outer side of the middle upper part of the transmission rod is sleeved with a polytetrafluoroethylene sleeve and a stainless steel sleeve supported by external equipment; the bottom of the tetrafluoro sleeve extends into the stainless steel sleeve from top to bottom and is fixedly connected with the stainless steel sleeve; the transmission rod, the tetrafluoro sleeve and the stainless steel sleeve can move freely.

In order to solve the problems that when materials are discharged into a dilution crystallization tank, the outlet of the dilution crystallization tank is blocked due to material accumulation, and when the materials need to be discharged from the dilution crystallization tank, the materials cannot be discharged due to the outlet blockage, so that potential safety hazards exist.

The utility model has reasonable structural design, can effectively prevent the materials from being accumulated to block the outlet and avoid the potential safety hazard, and has the advantages of simple installation, low cost and convenient operation. The utility model is suitable for equipment which needs to use a blocking mode to prevent materials from blocking a pipeline.

Detailed Description

Example 1

A device for preventing wax-like explosive from blocking a pipeline comprises a drawing handle 1, a tetrafluoro sleeve 2, a stainless steel sleeve 3, an equipment connecting point 4, a transmission rod 5 and a plugboard 6; the bottom of the transmission rod 5 is connected with a plugboard 6 for plugging a discharge pipe orifice 7 of a discharge pipeline 8, the top of the transmission rod 5 is connected with a drawing handle 1, and the outer side of the middle upper part of the transmission rod 5 is sleeved with a polytetrafluoroethylene sleeve 2 and a stainless steel sleeve 3 supported by external equipment; the bottom of the tetrafluoro sleeve 2 extends into the stainless steel sleeve 3 from top to bottom and is fixedly connected with the stainless steel sleeve 3; the transmission rod 5, the tetrafluoro sleeve 2 and the stainless steel sleeve 3 can move freely. As shown in FIG. 1, the bottom of the material discharge pipe 8 is closely attached to the bottom of the dilution crystallization tank, and if wax-like materials are directly discharged, the wax-like materials are easily accumulated at the material discharge pipe orifice to cause the pipe orifice to be blocked; according to the wax-like material feeding device, the material feeding pipe orifice is blocked through the inserting plate, and after the wax-like materials in the material feeding pipeline and the reaction kettle are crystallized, the crystallized materials cannot cause the blockage of the material feeding pipe orifice.

The tetrafluoro sleeve 2 consists of a bottom sleeve and a top sleeve with the outer diameter larger than that of the bottom sleeve; the bottom sleeve partially extends into the stainless steel sleeve 3 from top to bottom and is fixedly connected with the stainless steel sleeve 3. The tetrafluoro sleeve 2 is equivalent to the extension of the stainless steel sleeve 3, so that the up-and-down movement of the transmission rod is limited, the transmission rod is ensured to move up and down in the vertical direction basically, and deviation is avoided.

Example 2

The inserting plate 6 is formed by cutting off a part of a sphere on a plane, the discharging pipe 8 is horizontally arranged, the cut-off part of the sphere is a vertical surface and matched with the discharging pipe opening 7, and the sectional area is larger than the outer diameter of the discharging pipe opening 7.

As can be seen, the distance from the material discharge pipe to the bottom of the tank body is short, so that the wax-like material is easy to block the material discharge pipe orifice after being discharged. The cut surface of the inserting plate is opposite to the discharging pipe orifice and the area of the cut surface is larger than the outer diameter of the pipe orifice, so that the discharging pipe orifice is conveniently blocked by the structure. And under the natural state, the bottom that the picture peg was more just in time touched the jar body bottom of holding the material, had realized spacing automatically.

Example 3

The inserting plate 6 is in threaded connection with the transmission rod 5; the stainless steel sleeve 3 is provided with an equipment connecting point 4; the equipment connecting point 4 and the supporting equipment are welded or punched and are connected by using a bolt so as to fix the stainless steel sleeve; the inserting plate 6 is a polytetrafluoroethylene inserting plate; the transmission rod 5 and the equipment connection point 4 are made of stainless steel; the connection mode of the drawing handle 1 and the transmission rod 5 is welding. The polytetrafluoroethylene has certain elasticity, so that the discharging pipe orifice can be effectively plugged.

As shown in figure 1, a drawing handle 1 is used for pressing downwards, a material discharging pipe opening 7 is plugged by an inserting plate 6, then materials are placed into a dilution crystallization tank from a reaction kettle, the pressure and air agitation are opened, after the melted wax-like explosive is crystallized into particles, the inserting plate 6 is pulled up by the drawing handle 1, the materials flow out through a material discharging pipeline 8 along with water flow, and the condition that the materials are stacked and block the pipeline is effectively prevented.
