Description
Technical Field
The utility model relates to the technical field of blasting sealing, in particular to a directional sealing structure for a carbon dioxide blasting blockage removing device of a powder warehouse.
Background
The cement caking in the powder storehouse is caused by cement pre-hydration, and the moisture is mainly brought along with mixed materials, gypsum and other materials in grinding, and along with the higher temperature in the powder storehouse, the longer the material storage time is, the more caking on the wall of the powder storehouse, when the caking is to certain thickness, according to the change of the storage height in the storehouse, the automatic fall off can be realized, small blocky materials can flow into the decompression cone, the flow valve is blocked, and large blocky materials can be blocked at the feed inlet of the decompression cone, so that the feed inlet is blocked.
The carbon dioxide blocking removal device is adopted at the present stage to remove the blocking powder warehouse, and the carbon dioxide blocking removal device at the present stage only uses the blasting pipe to blast, and does not have any seal structure in the blasting pipe, so that after blasting, a plurality of caking dust can enter into the blasting pipe, and when the blasting pipe needs to be replaced with a heating rod in the blasting pipe again, dust caking and the like are required to be cleaned out together, which is time-consuming and labor-consuming.
Disclosure of Invention
According to the technical problem, the utility model provides the directional sealing structure with high sealing performance for the carbon dioxide blasting blockage removing device of the powder warehouse.
The utility model provides a directional sealing structure for a carbon dioxide blasting blocking removal device of a powder warehouse, which is characterized by comprising a positioning device and a guiding device, wherein the positioning device is connected with the guiding device.
The positioning device comprises a shell, a spring and a bidirectional sealing valve cone, wherein the spring is arranged in the shell and is connected with the bidirectional sealing valve cone, and air outlets are respectively formed in the left side and the right side of the upper portion of the shell.
The guiding device comprises a sealing ring and a guiding positioner, the sealing ring is arranged at the lower part of the cone of the bidirectional sealing valve, the guiding positioner is arranged at the lower part of the sealing ring, the bottom of the guiding positioner is conical, and a gap is reserved in the middle of the guiding positioner.
The beneficial effects of the utility model are as follows: the utility model relates to a directional sealing structure for a carbon dioxide blasting blocking remover of a powder warehouse, wherein the bottom of a guiding positioner is conical, a gap is arranged in the middle of the guiding positioner, when a blasting pipe enters the guiding positioner from bottom to top, only a bulge of the pipe body of the blasting pipe can pass through the empty slot, when the bulge position correctly enters the empty slot and is propped by the upper part of the empty slot, the direction of the blasting pipe does not move upwards any more, the positioning effect is achieved, air outlets on two sides of the blasting pipe correspond to air outlets of a shell, and the situation that the positions of the blasting pipe in the shell deviate to cause the air outlets to be out of correspondence is prevented, so that the blasting effect cannot be achieved; when the blasting is finished, the blasting tube moves downwards, and the bidirectional sealing valve cone moves downwards to the sealing ring, is tightly attached to the sealing ring, plays a role in sealing a pipeline, prevents powder in the powder warehouse from flowing into the tube, wherein the spring is connected with the bidirectional sealing valve cone, and the elastic action of the spring can prevent the bidirectional sealing valve cone from directly falling down to cause impact damage to the sealing ring.

Detailed Description
The technical scheme of the present utility model will be clearly and completely described in the following with reference to the accompanying drawings.
The utility model provides a directional sealing structure for a carbon dioxide blasting blocking removal device of a powder warehouse.
The positioning device comprises a shell 6, a spring 1 and a bidirectional sealing valve cone 2, wherein the spring 1 is arranged in the shell 6, the spring 1 is connected with the bidirectional sealing valve cone 2, and air outlets 61 are respectively arranged on the left side and the right side of the upper part of the shell 6.
The guiding device comprises a sealing ring 4 and a guiding positioner 5, the lower part of the two-way sealing valve cone 2 is provided with the sealing ring 4, the lower part of the sealing ring 4 is provided with the guiding positioner 5, the bottom of the guiding positioner 5 is conical, and a hollow groove is formed in the middle of the guiding positioner 5.
Examples
Starting the lifting equipment of the carbon dioxide blasting device to enable the blasting tube to push upwards, enabling the blasting tube to slowly pass through the guide positioner 5, jacking up the bidirectional sealing valve cone 2 upwards, enabling the blasting tube to not push upwards when the bulge moving to the blasting tube is just clamped in the empty slot of the guide positioner 5, enabling the air outlet hole of the blasting tube to just correspond to the air outlet hole 61 of the shell 6, and then enabling the staff to perform next blasting operation.
When blasting work is finished, the lifting device conveys the blasting tube downwards, the blasting tube slowly passes through the sealing ring 4, the bidirectional sealing valve cone 2 slowly descends under the action of the spring 1, and when the bidirectional sealing valve cone moves to the sealing ring 4, the bottom of the bidirectional sealing valve cone is just tightly attached to the sealing ring 4, so that powder in a powder warehouse is prevented from entering the pipeline.
