DETAILED DESCRIPTION

[0023] In order to make the technical personnel of the prior art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0024] As shown in Figures 1-4 A kind of lime bunker exhaust treatment device and lime bunker, including the bunker 1 being provided with inlet 11, further including the protective tube 2 being movably sleeved on inlet 11, hoop strip 3 being hingedly arranged in the protective tube 2, and rubber membrane 4 being fixedly installed between the hoop strip 3 connected with each other;

[0025] The end of hoop strip 3 is provided with a rotating seat 30, and the inner wall of protective tube 2 is provided with a concave hole 20 for the rotating seat 30 to move, and the plurality of hoop strips 3 are in a default state of being mutually converged to form a sharp cone, and the rotating seat 30 is fixedly installed with a protrusion 31 for plugging the concave hole 20.

[0026] Specifically, the protective tube 2 is assembled with the inlet 11 for a long time, and the inlet 11 is in a default state of being inclined, so that external dirt and rainwater cannot seep into the bunker 1 from the inlet 11, and the inlet 11 also has a blocking valve to prevent the raw materials in the bunker 1 from leaking downward, which is prior art and will not be described here.

[0027] Further, the protective tube 2 is specifically a corrosion-resistant and high-temperature-resistant hard plastic tube, the hoop strip 3 is specifically a corrosion-resistant and elastic metal strip, and the rubber membrane 4 is specifically a corrosion-resistant rubber, and the materials are prior art and will not be described here.

[0028] Further, the rotating seat 30 is installed with a torsion spring, and the torsion spring makes the ends of the plurality of hoop strips 3 abut against each other in a default state and form a triangular cone.

[0029] By inserting the pipeline end on the trolley into the protective tube 2, the plurality of hoop strips 3 are mutually opened and abut against the side wall of the pipeline end, and the rotating seat 30 is rotated in the concave hole 20, and the rubber membrane 4 is deformed to adhere to the side wall of the pipeline, thereby realizing reinforced sealing during the injection process, and the protrusion 31 opens the concave hole 20 during the deflection of the hoop strip 3 being pushed, so that the internal air in the protective tube 2 is extruded and discharged, and the airflow generated by the extrusion acts on the side wall of the pipeline to clean the connection position of the pipeline and the protective tube 2, thereby ensuring the sealing of the connection, and when the injection is completed, the pipeline is pulled out of the protective tube 2, the torsion spring on the rotating seat 30 is reset, and the plurality of hoop strips 3 quickly present a converging state, so that the circumferentially arranged hoop strips 3 present a triangular sharp cone towards the inside of the protective tube 2, to block the residual lime in the protective tube 2, avoid dust falling and entering the air, and realize exhaust treatment during the injection process.

[0030] As a further embodiment of the present application, the concave hole 20 further radially movably has a shaft block 32, and the rotating seat 30 rotates on the shaft block 32.

[0031] The inner wall of the protection pipe 2 is further provided with a receiving groove 22 for receiving the clamp strip 3, and the concave hole 20 is provided with an arc hole 21 for sliding the protrusion 31.

[0032] Specifically, a spring is fixedly installed between the shaft block 32 and the concave hole 20, and the shaft block 32 slides on the side wall of the concave hole 20, so that the shaft block 32 drives the rotating seat 30 to keep stable radial movement, so that the clamp strip 3 is connected with the end of the pipeline, and the depth of the arc hole 21 is greater than the depth of the concave hole 20, that is, the arc hole 21 is farther away from the shaft of the protection pipe 2.

[0033] During the extrusion of the clamp strip 3, the shaft block 32 is retracted into the concave hole 20, and the protrusion 31 enters the arc hole 21, so that the protrusion 31 blocks the arc hole 21 for ventilation, so that the inside of the protection pipe 2 is in a sealed state, and the leakage of lime during the injection of the pipeline is avoided. At the same time, the thick clamp strip 3 is pushed into the receiving groove 22, so as to tightly fit the side wall of the pipeline with the inner wall of the protection pipe 2, and the rubber film 4 can further enhance the sealing effect.

[0034] As a further embodiment of the utility model, the inner wall of the protection pipe 2 is further provided with a suction port 23 communicated with the concave hole 20, and the port of the protection pipe 2 is provided with an opening 231 communicated with the suction port 23.

[0035] Specifically, the cross-sectional area of the suction port 23 is greater than the cross-sectional area at the position communicated with the concave hole 20, so as to increase the air flow, and the opening 231 is communicated with the inner wall of the protection pipe 2.

[0036] During the process of inserting the pipeline into the protection pipe 2, the air flow discharged from the concave hole 20 enters the suction port 23, and the opening 231 blows and cleans the side wall of the pipeline, and after the pipeline is taken out from the protection pipe 2, the protrusion 31 returns to the default position, at this time the arc hole 21 is used as the ventilation in the protection pipe 2, and the inside of the protection pipe 2 is free of dust, which does not affect the air.

[0037] As another embodiment of the utility model, a plurality of sliding blocks 24 are fixedly installed on the inlet 11, and the inner wall of the protection pipe 2 is provided with a sliding hole 241 for sliding the sliding block 24.

[0038] Specifically, a spring is fixedly installed between the sliding block 24 and the sliding hole 241, and the inner wall of the protection pipe 2 is kept in close contact with the side wall of the inlet 11.

[0039] By repeatedly pushing and pulling the protective tube 2 to slide on the feeding opening 11, and accompanying the slider 24 compressing the spring deformation, the internal of the protective tube 2 constantly generates negative pressure and high pressure, the purpose is to use the vacancy at the arc hole 21 to suck the external air into the protective tube 2, and because the feeding opening 11 is in the open state, the part of the circulating suction airflow can supplement the residual lime in the protective tube 2 into the stock bin 1 again, reduces the residual lime in the protective tube 2, avoids dust leakage to the external air, and reduces the lime resource waste.

[0041] Specifically, the slider 24 is fixedly provided with a rubber block, and the rubber block is used for closing the gas supplementing opening 26 in the default state, avoiding the external dirt from seeping into the protective tube 2.

[0042] Further, the slider 24 and the sliding hole 241 are further provided with a ventilation gap, and the feeding process of the stock bin 1 is carried out in the rainy weather.

[0043] Through the process of pushing and pulling the protective tube 2, the external air enters from the gas supplementing opening 26, and under the action of the slider 24, the airflow is sent into the protective tube 2 from the flow guiding hole 25, so that the protective tube 2 is blown by more clean airflow, the power of the residual lime in the protective tube 2 sent into the stock bin 1 through the feeding opening 11 is increased, and the lime raw material waste is reduced.

[0044] Working principle: by inserting the pipeline end on the trolley into the protective tube 2, the plurality of hoop strips 3 are mutually opened and abut against the side wall of the pipeline end, and the rotating seat 30 is rotated in the concave hole 20, and the rubber film 4 is deformed and attached to the side wall of the pipeline, so that the sealing is strengthened during the feeding process, and the convex 31 opens the concave hole 20 during the deflection of the hoop strip 3, so that the internal air in the protective tube 2 is extruded and discharged, and the airflow generated by the extrusion acts on the side wall of the pipeline, which is used for cleaning the connection position of the pipeline and the protective tube 2, and guarantees the sealing property of the connection, and when the feeding is completed, the torsional spring on the rotating seat 30 is reset during the process of pulling out the pipeline from the protective tube 2, and the plurality of hoop strips 3 quickly present the close state, the hoop strips 3 arranged in the circle present the triangular pyramid towards the internal of the protective tube 2, which is used for blocking the residual lime in the protective tube 2, avoiding the floating dust from falling and entering into the air.

[0045] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
