In addition, the upper part of the cone air cannon is blocked, the labor intensity is high in the blockage clearing process, and the collapse blowout danger is high; and the air cannon is used for cleaning the materials in the lower part, so that the impact force is large, large-area material leakage around the batching scale and the conveying belt is caused, the cleaning is difficult, and the safety problem exists during the material cleaning.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a clay reservoir bottom cleaning device, which aims to solve the problems in the prior art in the background art.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the clay warehouse bottom cleaning device comprises a clay warehouse cone and an air cannon arranged on the outer wall of the clay warehouse cone, wherein the air outlet end of an air injection pipe connected with the air cannon extends into the clay warehouse cone, the air outlet end of the air injection pipe is connected with an annular spray pipe, the annular spray pipe is tightly attached to and fixed on the inner wall of the clay warehouse cone, a plurality of nozzles are arranged on the annular spray pipe at intervals along an annular ring, and the nozzles are arranged along the inner wall of the clay warehouse cone.

Preferably, a plurality of nozzles are arranged above and below the annular spray pipe at intervals along the annular ring respectively, so that the upper part and the lower part of the cone can be cleaned comprehensively.

Preferably, a branch pipe is connected between the annular spray pipe and the nozzle, and the cleaning range of the inner wall of the cone is enlarged.

Preferably, the nozzle is a duckbill nozzle, and the effect of cleaning and blowing the sticky materials on the bin wall is good.

Preferably, the air ejector pipe is provided with an electromagnetic valve, and the electromagnetic valve is connected with a central control system for cement production. The blowing air quantity is controlled by the electromagnetic valve, so that the impact force during blanking can be effectively reduced, and the material is prevented from being sprayed around the batching scale and the belt, so that secondary pollution is avoided.

Compared with the defects and shortcomings of the prior art, the utility model has the following beneficial effects:

according to the clay warehouse cone, the annular blowing pipeline is additionally arranged in the clay warehouse cone and connected with the air cannon outside the cone, the plurality of nozzles are arranged on the annular blowing pipeline at intervals, multi-point cleaning is achieved, the cone wall sticky material cleaning effect is good, and the stability of batching and the reliability of equipment are improved. The KH qualification rate of the milled raw material is improved to more than 90 percent, and the reliability of the raw material mill reaches 100 percent. The shed does not need to be cleaned manually, so that the labor intensity of workers is reduced, and the risk of blockage cleaning operation is avoided. In addition, the blowing air quantity is controlled by the electromagnetic valve, so that the blanking impact force is reduced, the problems of material scattering and material spraying during air cannon blockage clearing are solved, and the environment under a blending warehouse is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, according to the clay warehouse bottom cleaning device provided by the utility model, a mounting hole is formed in the side wall of a clay warehouse cone 1, an air injection pipe 3 of an air gun 2 on the outer wall of the clay warehouse cone 1 extends into the clay warehouse cone 1 through the mounting hole, and the mounting hole is sealed and fixed. Annular spray tube 4 is add to clay storehouse cone 1 inside, the radian of

annular spray tube

4 and 1 inner wall looks adaptation of clay storehouse cone, hug closely annular spray tube 4 and be fixed in on 1 inner wall of clay storehouse cone, the end of giving vent to anger of jet tube 3 is connected on annular spray tube 4 and the intercommunication, the annular ring interval along annular spray tube 4 is equipped with a plurality of nozzles 5, carry out the multiple spot clearance to the cone inner wall, nozzle 5 adopts the duckbilled type, and set up along clay storehouse cone 1's inner wall, make the 5 openings of nozzle can blow the sizing on the internal wall of spray cone, blow off cone inner wall sizing, it is effectual to clear the blowing. In order to comprehensively clean the upper part and the lower part of the cone, a plurality of nozzles 5 (refer to fig. 3) are arranged above and below the annular nozzle 4 at intervals along the annular ring respectively, the nozzles 5 above the annular nozzle 4 clean the upper part of the inner wall of the cone, and the nozzles 5 below the annular nozzle 4 clean the upper part of the inner wall of the cone, so that the cleaning is comprehensive and thorough. As the inner cavity of the clay reservoir cone 1 is larger, in order to enlarge the cleaning range of the inner wall of the cone, the nozzles 5 are spaced at a certain distance in the vertical direction, and a branch pipe 6 is connected between the annular nozzle 4 and the nozzles 5, as shown in figures 2-3.

Because the impact force is large when the air cannon is directly used for filling materials at the lower part of the cone, the large-area leakage phenomenon around the burden scale and the belt can be caused, the electromagnetic valve 7 is additionally arranged on the air injection pipe 3, and the electromagnetic valve 7 is connected into a central control system for cement production and is controlled by the central control system. Because the blowing amount of the electromagnetic valve 7 is small, the nozzle 5 is controlled by the electromagnetic valve 7 to blow the sticky materials, the impact force during blanking is small, the materials are not suitable to be sprayed around the batching scale and the belt, secondary pollution is not formed, the cleaning workload is reduced, and meanwhile, the safety is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
