Description

Technical Field

[0001] The invention relates to the technical field of bag dust collector manufacturing, and in particular to a quick cleaning device for a bag dust collector box before spraying. Background Art

[0002] A bag-type dust collector is a device used to filter solid particles and dust in the air. It is suitable for capturing fine, dry, non-fibrous dust. The filter bags are made of textile filter cloth or non-textile felt, and use the filtering effect of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag-type dust collector, the large particles and high specific gravity of the dust settle down due to gravity and fall into the ash hopper. When the gas containing fine dust passes through the filter bag, the dust is retained, so that the gas is purified.

[0003] Bag dust collectors are often used for dust treatment and air purification in industrial production. In industrial environments, bag dust collectors need to have good adaptability. Therefore, in the manufacturing process of bag dust collectors, the bag dust collector box needs to be protected by paint to prevent the surface of the bag dust collector box from being corroded by the gas in the industrial environment. Quick cleaning of the bag dust collector box is a very important step in implementing paint protection. This step can affect the spraying effect and the overall quality.

[0004] The existing cleaning method of the bag dust collector box is to clean the box surface by manually holding a high-pressure nozzle. However, on the one hand, humans can only use a single nozzle. For a large area of ​​the box, it takes a long time to complete the cleaning, and the work efficiency is low. On the other hand, since humans have a low grasp and maintenance of the flushing distance, when there are uneven surfaces on the box or the degree of impurity adhesion on the surface of the box varies, if the flushing distance is not appropriate, the flushing effect of the box surface is uneven or low, which in turn affects the overall spraying effect. After long-term use, the paint surface in the area where the flushing effect is not good is prone to cracking, which is not conducive to the long-term use of the bag dust collector box.

[0038] During specific operation, the motor 222 is operated to control the screw rod 226 to rotate and drive the rightmost moving seat 224 to move along the guide rod 1 227. The connecting arm 223 and the short-circuit arm 225 are connected and linked to make each moving seat 224 move synchronously and equidistantly, so that the main nozzle 23 is adjusted according to the distribution position of the concave or convex surface on the box body, so that the main nozzle 23 is opposite to the concave or convex surface, thereby meeting the comprehensive liquid spray cleaning of the concave and convex surfaces of the box body.

[0039] See also Figure 1 and Figure 3 The length adjustment component 21 includes a hinge arm 216 hinged on the rear side of the telescopic nozzle 24. The two hinge arms 216 at the same main nozzle 23 are distributed in a V shape and hinged on the same movable sleeve 215.

[0047] See also Figure 5 The inner wall of the main nozzle 23 is symmetrically provided with a plurality of guide grooves 232 equidistantly distributed around the circumference, and the outer wall of the telescopic nozzle 24 is fixedly connected with a guide block 231 at a position corresponding to each guide groove 232 , and the guide block 231 is slidably connected to the guide groove 232 .

[0048] During operation, the guide block 231 and the guide groove 232 are connected in coordination to prevent the telescopic nozzle 24 from rotating, thereby ensuring that the nozzles 25 of the telescopic nozzle 24 and the main nozzle 23 remain flush, thereby achieving smooth and effective spraying of the cleaning liquid.

[0049] See also Figure 2 The lower side of the electric slider 2 36 is fixedly connected to a multi-head pipe 5, one of the pipe openings of the multi-head pipe 5 is connected to the output pipe opening of an external high-pressure pump (the high-pressure pump is not shown in the figure) through a pipeline, the input pipe opening of the high-pressure pump is connected to an external container (the container is not shown in the figure) storing cleaning liquid through a pipeline, and the remaining pipe openings of the multi-head pipe 5 are respectively connected to each connecting pipe 26 through a pipeline.

[0051] See also Figure 1-Figure 6 , When in use: S1: Place the box of the bag dust collector on the support 1 through the sling and arrange it neatly, and then adjust it according to the convex surface distribution position of the actual flushing surface of the box, and control the screw rod 226 to rotate through the operation of the motor 222 to drive the rightmost moving seat 224 to move along the guide rod 1 227, and the connection linkage of the connecting arm 223 and the short-circuit arm 225 makes each moving seat 224 move synchronously, so that the main nozzle 23 corresponds to the convex surface, and at the same time, the electric push rod 1 212 controls the mounting block 213 to drive the connecting rod 214 to move up and down, and the connecting rod 214 drives each movable sleeve 215 to move up and down to control the two hinge arms 216 in a linkage manner, and the telescopic nozzle 24 is controlled to be extended and retracted through the two hinge arms 216, and the number of nozzles 25 is increased by extending the telescopic nozzle 24, and the overall spray range is expanded to make the spray range adapt to the width of the convex surface of the box.

[0052] S2: The liquid spraying mechanism 2 is controlled to approach the surface of the box body by the electric push rod 2 34, and then the cleaning liquid in the filling tank is pumped into the multi-head pipe 5 by the high-pressure pump, and the multi-head pipe 5 disperses the high-pressure cleaning liquid into each connecting pipe 26, and then the high-pressure cleaning liquid is input into the main nozzle 23 through the connecting pipe 26. The main nozzle 23 and the telescopic nozzle 24 cooperate to spray the cleaning liquid from the nozzle 25, and the cleaning liquid sprayed by the high-pressure spray is synchronously sprayed on the surface of the box body for decontamination. At the same time, the electric slider 1 33 moves along the guide rod 3 35, so that the electric slider 2 36 drives the liquid spraying mechanism 2 to move downward along the box body.

[0053] S3: After the convex surface is cleaned, the spray range is adjusted according to the width of the concave surface, and the electric slider 2 36 is moved along the guide rod 2 31, so that the electric slider 1 33 drives the spray mechanism 2 to move horizontally along the box body, so that each main nozzle 23 moves to the position corresponding to the concave surface, and then the electric push rod 2 34 is used to fine-tune the spray mechanism 2 to approach the multiple concave surfaces of the box body, and then the spray cleaning is started, and the spray mechanism 2 is moved from bottom to top.

[0054] S4: After one side is cleaned, the motor 133 controls the gear 132 to rotate and drives the gear ring 135 to control the rotating seat 134 to rotate 90°, so that the support plate 131 rotates 90° around the support, so that the spray mechanism 2 faces the other side of the box, and then repeats the steps S2-S3 to complete the cleaning of this side. The cleaning process of the remaining sides of the box is the same.

[0055] S5: During the cleaning process of the box, the through hole 11 will recover the downstream spray liquid, and the recovered spray liquid will be quickly concentrated to the inner edge of the support 1 through the truncated cone ring wall 12, and then the used cleaning liquid will be discharged from the liquid outlet.
