Description

Technical Field

[0001] The invention belongs to the technical field of elbow spraying processing, and specifically relates to an elbow environmentally friendly spraying equipment and a use method thereof. Background Art

[0002] Elbows are a type of pipe fittings that change the direction of the pipeline. According to different production processes, they can be divided into: welded elbows, stamped elbows, cast elbows, etc. During the production and processing of elbows, corresponding spraying equipment is required to spray the outer and inner walls of the elbows. Spraying improves the aesthetics, corrosion resistance and wear resistance of the elbows.

[0003] Currently, common elbow spraying equipment is mainly composed of a spraying system, a clamping structure and a control system. When in use, the elbow is clamped and positioned through the clamping structure, and the paint is guided through the spraying system to spray the inner and outer pipe walls of the elbow.

[0004] Since the inner tube wall of the elbow is curved, and the nozzles of most elbow spraying equipment in the prior art are arranged vertically, when the nozzle moves in the elbow, the distance around the nozzle and the inner tube wall of the elbow will continue to change. This will make the coating thickness of the inner tube wall of the elbow close to the nozzle thicker than the coating thickness of the inner tube wall of the elbow away from the nozzle, resulting in poor uniformity in the spraying treatment of the elbow and waste of some coating. The waste of coating will not only increase the production and processing cost of the elbow, but the escaped coating will pollute the processing environment, making the efficiency and environmental protection of the elbow spraying equipment poor.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

The linkage frame is driven to rotate by controlling the operation of the second drive motor, so as to facilitate the driving of the inner spray disc to spray the inner wall of the elbow.

[0017] In one or more embodiments of the present invention, a plurality of evenly distributed conducting sleeves are fixedly mounted on the inner side of the outer tube spray ring and the outer side of the inner spray disc. The plurality of conducting sleeves serve as assembly limiters and liquid conduction for the threaded inner tube. The threaded inner tubes are threadedly connected inside the plurality of conducting sleeves. The threaded inner tube serves to connect the nozzle and the conducting sleeve, and the spraying position of the nozzle is adjusted by controlling the telescopic state of the conducting sleeve. A nozzle is fixedly connected to one end of the plurality of threaded inner tubes outside the conducting sleeve. The paint is sprayed and discharged through the nozzle.

[0018] In one or more embodiments of the present invention, a liquid storage tank is installed in the base of the equipment. The liquid storage tank plays the role of storing the paint. A liquid delivery pump is connected to one side of the liquid storage tank. The paint stored in the liquid storage tank is extracted and pressurized by controlling the operation of the liquid delivery pump. A liquid delivery pipe is connected to the liquid outlet of the liquid delivery pump. The liquid delivery pipe plays the role of connecting the liquid delivery pump and the conducting liquid pipe, so that the paint extracted by the liquid delivery pump is delivered to the conducting liquid pipe.

[0019] In one or more embodiments of the present invention, the end of the liquid delivery pipe away from the liquid delivery pump is connected to a conducting liquid pipe. The conducting liquid pipe serves to connect the liquid delivery pipe with the inner liquid discharge pipe, so as to facilitate the delivery of the paint transported in the conducting liquid pipe to the inner liquid discharge pipe. The end of the conducting liquid pipe located in the outer spray rack is fixedly connected to the inner liquid discharge pipe, and the inner liquid discharge pipe is connected to multiple groups of conducting sleeves in the outer tube spray ring.

[0020] In one or more embodiments of the present invention, one end of the conductive liquid pipe located in the arc connecting rod is fixedly connected to a flow guiding inner pipe, and the flow guiding inner pipe is connected to multiple groups of conductive sleeves located in the inner spray plate. The flow guiding inner pipe serves to connect the conductive liquid pipe and the inner spray plate, so as to facilitate the conveying of paint into multiple groups of conductive sleeves through the flow guiding inner pipe.

[0021] In one or more embodiments of the present invention, the positioning and suction assembly includes a negative pressure drainage tube, which is fixedly mounted in the partition. The negative pressure drainage tube serves to store, limit and control the movement of the piston rod. A pair of piston rods are slidably mounted in the negative pressure drainage tube. The pair of piston rods serves to support, fix and control the movement of the positioning block. One end of the pair of piston rods located outside the negative pressure drainage tube is fixedly connected to a positioning block. The elbow is squeezed and positioned by the interaction between the pair of positioning blocks and the elbow.

[0022] A method for using an elbow environmental protection spraying device comprises the following steps:

[0023] S1. Place the elbow that needs to be sprayed on the outer tube on the inner tube positioning seat, and place the elbow that needs to be sprayed on the inner tube on the outer tube positioning seat, generate compressed gas by controlling the operation of the compressed air pump, and transport the compressed gas to multiple groups of control air cylinders along the exhaust pipe and the delivery air pipe, so that the inner extrusion top block will pop out under the action of the compressed gas, and the inner wall of the elbow is supported and positioned by the movement of the multiple groups of inner extrusion top blocks;

[0024] S2. At the same time, compressed gas is transported along the guide air pipe, the ventilation ring pipe and the control air pipe to the multiple sets of outer tube positioning air cylinders, so that the outer extrusion top blocks extend out of the multiple sets of outer tube positioning air cylinders under the action of the compressed gas, and the outer wall of the elbow is clamped and positioned by the extension of the multiple sets of outer extrusion top blocks;

[0025] S3, and the compressed gas in the compressed air pump can be transported to the negative pressure drainage tube along the driving air pipe, so that a pair of driving piston blocks in the negative pressure drainage tube can slide in the negative pressure drainage tube under the action of the compressed gas, and the sliding of the driving piston blocks drives the positioning blocks to move, thereby squeezing and positioning the elbow;

[0026] S4. The paint stored in the liquid storage tank is extracted and pressurized by controlling the operation of the liquid delivery pump. The paint can be delivered to the outer tube spray ring along the liquid delivery pipe, the guide liquid pipe, and the drainage inner pipe. The outer tube of the elbow is sprayed by spraying the paint through multiple groups of nozzles. The paint is delivered to the inner spray plate along the liquid delivery pipe and the guide inner pipe, and is sprayed to the inner tube of the elbow through multiple groups of nozzles on the outer side of the inner spray plate;

[0027] S5. During operation, the compressed air pump can extract the air in the inner top pad through the air delivery pipe, so that the inner top pad is in a negative pressure state, and the waste liquid or waste gas generated by spraying on the inner wall of the elbow can be collected and diverted through the internal negative pressure diversion hole, and the waste liquid or waste gas generated by spraying on the outer wall of the elbow can be collected and diverted through the external negative pressure diversion hole. The collected waste liquid or waste gas can be transported to the collecting and purifying cylinder along the drainage pipe, and can be accumulated and collected in the collecting and purifying cylinder, and the waste gas can be discharged after being adsorbed and purified by the adsorption filter plate.

[0028] Compared with the prior art, the present invention can evenly spray the inner and outer pipe walls of the elbow through the setting of corresponding structures, which greatly improves the quality of the spraying treatment of the elbow. At the same time, it reduces the waste of paint during the spraying process and significantly improves the efficiency and environmental protection of the spraying treatment of the elbow.

Compressed gas is delivered to the negative pressure drainage pipe 401 through the driving air pipe 406, so as to facilitate the driving control of the driving piston block 404.

[0089] It is worth noting that an inner negative pressure guide hole is provided on one side of the positioning block 403 close to the outer tube positioning seat 204. The waste liquid and waste gas generated by spraying on the inner wall of the elbow are collected and guided through the inner negative pressure guide hole.

[0090] Specifically, an external negative pressure guide hole is provided on one side of the positioning block 403 close to the inner tube positioning seat 201. The waste liquid or waste gas generated by spraying on the outer wall of the elbow is collected and guided through the external negative pressure guide hole.

At the same time, the waste liquid or exhaust gas in the collecting and purifying cylinder 408 can be diverted by the rotation of the multiple groups of adsorption filter plates 412.

[0097] A method for using an elbow environmental protection spraying device comprises the following steps:

[0098] S1. Place the elbow that needs to be sprayed on the outer tube on the inner tube positioning seat 201, and place the elbow that needs to be sprayed on the inner tube on the outer tube positioning seat 204. Control the operation of the compressed air pump 215 to generate compressed gas, and the compressed gas is transported to the multiple groups of control cylinders 202 along the exhaust pipe 216 and the delivery pipe 209. By transporting compressed gas to the multiple groups of control cylinders 202, the inner extrusion top block 203 will pop out under the action of the compressed gas, and the inner wall of the elbow is supported and positioned by the movement of the multiple groups of inner extrusion top blocks 203;

[0099] S2. At the same time, the compressed gas is transported to the multiple sets of outer tube positioning gas cylinders 205 along the guide gas pipe 214, the ventilation ring pipe 213 and the control gas pipe 212, so that the outer extrusion top blocks 206 extend out of the multiple sets of outer tube positioning gas cylinders 205 under the action of the compressed gas, and the outer wall of the elbow is clamped and positioned by the extension of the multiple sets of outer extrusion top blocks 206;

[0100] S3. In addition, the compressed gas in the compressed air pump 215 can be transported to the negative pressure drainage tube 401 along the driving air pipe 406, so that a pair of driving piston blocks 404 in the negative pressure drainage tube 401 can slide in the negative pressure drainage tube 401 under the action of the compressed gas, and the sliding of the driving piston blocks 404 drives the positioning blocks 403 to move, thereby squeezing and positioning the elbow;

[0101] S4. Subsequently, the paint stored in the liquid storage tank 312 can be extracted and pressurized by controlling the operation of the liquid delivery pump 313. The paint can be delivered to the outer tube spray ring 303 along the liquid delivery pipe 314, the guide liquid pipe 315, and the drainage inner pipe 316. The outer tube of the elbow is sprayed by spraying the paint through multiple groups of nozzles 311. The paint is delivered to the inner spray plate 306 along the liquid delivery pipe 314 and the guide inner pipe 317, and sprayed to the inner tube of the elbow through multiple groups of nozzles 311 outside the inner spray plate 306.

[0102] S5. Furthermore, the first drive motor 307 can be controlled to drive the flip shaft 301 to rotate, and the outer tube spray ring 303 can be driven to move around the outer tube of the elbow by the rotation of the flip shaft 301, so as to spray the outer tube of the elbow. The second drive motor 308 can be controlled to drive the linkage frame 304 to rotate, so as to push the inner spray disc 306 to move along the inner tube of the elbow, and the inner tube of the elbow can be sprayed by the movement of the inner spray disc 306, so as to achieve uniform spraying of the inner tube and the outer tube of the elbow;

[0103] S6. In addition, during operation, the compressed air pump 215 can extract the air in the inner top pad 208 through the delivery air pipe 209, so that the inner top pad 208 is in a negative pressure state, and the waste liquid or waste gas generated by the spraying of the inner wall of the elbow is collected and diverted through the inner negative pressure diversion hole, and the waste liquid or waste gas generated by the spraying of the outer wall of the elbow is collected and diverted through the outer negative pressure diversion hole. The collected waste liquid or waste gas can be transported to the collection and purification cylinder 408 along the drainage pipe 407, and can be accumulated and collected in the collection and purification cylinder 408, and the waste gas is discharged after being adsorbed and purified by the adsorption filter plate 412.
