Description

Technical Field

[0001] This utility model relates to the field of slurry pump processing technology, specifically a painting device for slurry pump processing. Background Technology

[0002] A slurry pump is a pump used to transport solid-liquid mixtures or liquids containing solid particles. It is widely used in mining, chemical, power, environmental protection and other industries. In order to achieve long-term stable operation of slurry pumps in dusty and highly corrosive working conditions such as mining, chemical, and water conservancy, it is usually necessary to use a painting device to paint the slurry pumps during the manufacturing process.

[0003] When painting existing slurry pumps, the slurry pump is first fixed on the processing table. Then, part of the process involves workers holding a paint gun and walking around the slurry pump to spray its surface, while another part involves spraying the slurry pump using multiple sets of nozzles surrounding it.

[0004] The following problems exist: the former requires workers to hold the spray gun and move around constantly during the spraying process, which increases the workload of the workers and results in low painting efficiency; the latter has the spray nozzle surrounding the slurry pump, which is not flexible when facing slurry pumps of different heights and will cause paint waste. Therefore, we propose a painting device for slurry pump processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a painting device for slurry pump processing. By adjusting the mechanism to control the movement of the spray head, it can meet the painting work of slurry pumps of different heights within a certain range, improve the flexibility of equipment use, reduce paint waste, and reduce the workload of workers, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a painting device for slurry pump processing, including a painting chamber, an adjustable spray head inside the painting chamber, and an adjustment mechanism;

[0007] Adjustment mechanism: It includes limit rods, movable plate, mounting holes, fixed rods, connecting rods, sliding plate, and sensing components. Limit rods are provided on both the front and rear sides of the right side of the paint spray chamber. A movable plate is slidably connected between the two limit rods. A nozzle is installed in the mounting hole on the left side of the movable plate. A connecting rod is provided at the rear end of the left side of the movable plate. Fixed rods are provided on both the front and rear sides of the left side of the paint spray chamber. The connecting rod is slidably connected to the outer surface of the fixed rod on the rear side through a sliding hole on the left side. A sliding plate is slidably connected between the two fixed rods. The connecting rod is located below the sliding plate. A sensing component is provided inside the paint spray chamber. The movement of the nozzle is controlled by the adjustment mechanism. Within a certain range, it can meet the painting work of slurry pumps of different heights, improve the flexibility of equipment use, reduce paint waste, and reduce the workload of workers.

[0008] Furthermore, it also includes a controller, which is located on the left side of the spray booth. The input terminal of the controller is electrically connected to an external power source to facilitate the normal operation of the equipment.

[0009] Furthermore, the sensing component includes a photoelectric sensor, a contact sensor, and rubber protrusions. A photoelectric sensor is provided on the right side of the sliding plate, and contact sensors are provided on the rear side of the lower surface of the sliding plate and the rear side of the bottom wall of the spray booth. The side of the contact sensor facing the connecting rod is a sensing surface. Rubber protrusions are provided on both the upper and lower sides of the left end of the connecting rod. The output ends of the photoelectric sensor and the contact sensor are electrically connected to the input end of the controller, which facilitates the sensing adaptation to the spraying operation of slurry pumps at different heights.

[0010] Furthermore, the adjustment mechanism also includes electric push rod one and electric push rod two. Electric push rod two and electric push rod one are respectively installed in the mounting ports on the left and right sides of the top wall of the spray booth. The lower ends of the telescopic shafts of electric push rod one and electric push rod two are fixedly connected to the upper surfaces of the movable plate and the sliding plate, respectively. The input ends of electric push rod one and electric push rod two are electrically connected to the output end of the controller, which facilitates the control of the height of the spray nozzle and the photoelectric sensor.

[0011] Furthermore, a paint tank is installed in the placement opening on the right wall of the spray booth. The outlet on the left side of the paint tank is connected to the inlet of the spray head through a conveying pipe. The left and right ends of the conveying pipe are respectively connected in series with a corrugated pipe with steel wire and a paint pump. The input end of the paint pump is electrically connected to the output end of the controller to facilitate the spraying operation.

[0012] Furthermore, it also includes a rotating mechanism, which includes a rotating shaft, a positioning plate, threaded positioning holes, and a motor. The bottom wall of the spray booth is rotatably connected to the positioning plate via the rotating shaft. The outer surface of the positioning plate is provided with evenly distributed threaded positioning holes. The inside of the spray booth is equipped with a motor. The upper end of the motor's output shaft is fixedly connected to the lower end of the rotating shaft. The input end of the motor is electrically connected to the output end of the controller to facilitate the control of the slurry pump rotation.

[0013] Furthermore, the rotating mechanism also includes balls and annular grooves. Balls are rotatably connected in the evenly distributed clearance holes on the lower surface of the positioning plate. Annular grooves are provided on the bottom wall of the spray booth. The outer surfaces of the four balls are in contact with the bottom wall of an annular groove to reduce friction.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This painting device for slurry pump processing has the following advantages:

[0015] The sliding plate drives the photoelectric sensor to move along the fixed rod. Based on the height of the slurry pump, the range of movement of the movable plate and the nozzle along the limit rod is limited. When the sensing surface of the contact sensor is touched by the rubber protrusion, the electric push rod changes its working mode, causing the nozzle to move up and down repeatedly within the limited range. In conjunction with the intermittent rotation of the slurry pump, the slurry pump is painted. Within a certain range (the stroke of the electric push rod), the painting work of slurry pumps of different heights can be met, which improves the flexibility of equipment use, reduces paint waste, and reduces the workload of the staff.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a painting device for slurry pump processing, including a painting chamber 1 (the upper surface of the painting chamber 1 is provided with an air inlet pipe, the left side of the painting chamber 1 is provided with evenly distributed exhaust ports, and the front side of the painting chamber 1 is provided with a switch door), the interior of the painting chamber 1 is provided with an adjustable spray head 7, and also includes an adjustment mechanism 3, and a controller 2, which is located on the left side of the painting chamber 1. The input terminal of the controller 2 is electrically connected to an external power supply. A paint tank 4 is provided in the placement opening on the right wall of the painting chamber 1 (the right side of the paint tank 4 is provided with a glass observation window for observing the remaining paint), and the discharge port on the left side of the paint tank 4 is connected to the inlet of the spray head 7 through a conveying pipe 5. The left and right ends of the conveying pipeline 5 are respectively connected in series with a corrugated pipe 8 with steel wire and a paint pump 6. The input end of the paint pump 6 is electrically connected to the output end of the controller 2. It also includes a rotating mechanism 9, which includes a rotating shaft 91, a positioning plate 92, threaded positioning holes 93, and a motor 94. The bottom wall of the spray booth 1 is rotatably connected to the positioning plate 92 through the rotating shaft 91. The outer surface of the positioning plate 92 has evenly distributed threaded positioning holes 93. The inside of the spray booth 1 is equipped with a motor 94 (the motor 94 can be a stepper motor. The rotation of the stepper motor is a step-by-step movement at a fixed angle. The rotation angle depends on the number of pulses. The rotation angle of the positioning plate 92 can be controlled by controlling the number of pulses). The output of the motor 94 is... The upper end of the shaft is fixedly connected to the lower end of the rotating shaft 91. The input end of the motor 94 is electrically connected to the output end of the controller 2. The rotating mechanism 9 also includes balls 95 and annular grooves 96. Balls 95 are rotatably connected in the evenly distributed clearance holes on the lower surface of the positioning plate 92. Annular grooves 96 are provided on the bottom wall of the paint spraying chamber 1 (the central axes of the annular grooves 96, the rotating shaft 91, and the positioning plate 92 are all coincident). The outer surfaces of the four balls 95 are in contact with the bottom wall of one annular groove 96. The external hot air blower is connected to the inside of the paint spraying chamber 1 through the air inlet pipe on the paint spraying chamber 1. Then, the switch door on the front side of the paint spraying chamber 1 is opened. The flange at the bottom of the slurry pump is fixed to the positioning plate 92 through the threaded positioning hole 93 using fixing bolts. Then, under the control of controller 2, paint pump 6 works, and paint pump 6 transports the paint in paint tank 4 to nozzle 7 through conveying pipe 5. The paint is sprayed from nozzle 7 onto the right side of slurry pump. Due to the presence of steel wire corrugated pipe 8, conveying pipe 5 is more flexible. At this time, the output shaft of motor 94 drives positioning plate 92 to rotate 90 degrees through rotating shaft 91, causing slurry pump to rotate 90 degrees. Due to the presence of ball bearing 95 and annular groove 96, friction is reduced, making the rotation of positioning plate 92 smoother. Through the up and down movement of nozzle 7 and the rotation of slurry pump, slurry pump is painted. After the painting is completed, external hot air blower provides hot air to the paint booth 1 to dry the painted slurry pump.

[0023] Adjustment mechanism 3 includes a limiting rod 31, a movable plate 32, a mounting hole 33, a fixed rod 34, a connecting rod 35, a sliding plate 36, and a sensing component 37. Limiting rods 31 are provided on both the front and rear sides of the right side inside the spray booth 1. A movable plate 32 is slidably connected between the two limiting rods 31. A nozzle 7 is installed in the mounting hole 33 on the left side of the movable plate 32. A connecting rod 35 is provided at the rear end of the left side of the movable plate 32. Fixed rods 34 are provided on both the front and rear sides of the left side inside the spray booth 1. The connecting rod 35 is slidably connected to the outer surface of the rear fixed rod 34 through a sliding hole on the left side. A sliding plate 36 is slidably connected between the two fixed rods 34. The connecting rod 35 is located below the sliding plate 36. A sensing component 37 is provided inside the spray booth 1. The sensing component 37 includes a photoelectric sensor 371, a contact sensor 372, and a rubber protrusion 373. The photoelectric sensor 371 is located on the right side of the sliding plate 36. (The photoelectric sensor 371 is a diffuse reflection type photoelectric switch. The detection head of the photoelectric sensor 371 contains a light emitter and a light receiver. When the slurry pump is present, it blocks the light and partially reflects it back. The light receiver receives the light signal and transmits it to the controller. An E3ZG-LS series sensor can be selected. The detection distance can be set; objects beyond this distance, even if present, will not trigger a signal due to insufficient reflected light intensity.) The contact sensor 372 is located on the rear side of the lower surface of the sliding plate 36 and the rear side of the bottom wall of the spray booth 1. The side of the contact sensor 372 facing the connecting rod 35 is the sensing side. (The contact sensor 372 can be a piezoelectric contact sensor. Based on the positive piezoelectric effect, when the sensing surface is subjected to external mechanical force, equal and opposite charges are generated. After the mechanical force disappears, the charges also disappear.) Rubber protrusions 373 are provided on both the upper and lower sides of the left end of the connecting rod 35. The output ends of the photoelectric sensor 371 and the contact sensor 372 are electrically connected to the input end of the controller 2, respectively. The adjustment mechanism 3 also includes an electric push rod 38 and an electric push rod 39. The electric push rod 39 and the electric push rod 38 are respectively installed in the mounting ports on the left and right sides of the top wall of the spray booth 1. (When the electric push rod 38 and the electric push rod 39 are subjected to radial force, due to the presence of the limiting rod 31 and the fixing rod 34, the electric push rod 38 and the electric push rod 39 are...) This provides force protection and limit, making the operation of electric push rod 38 and electric push rod 39 more stable. The lower ends of the telescopic shafts of electric push rod 38 and electric push rod 39 are fixedly connected to the upper surfaces of movable plate 32 and sliding plate 36, respectively. The input ends of electric push rod 38 and electric push rod 39 are electrically connected to the output end of controller 2. After adjusting the detection distance of photoelectric sensor 371, the door is closed. Under the control of controller 2, electric push rod 38 starts working. The telescopic shaft of electric push rod 38 drives movable plate 32 to move downward along limit rod 31 until the lower rubber protrusion 373 contacts the sensing surface of contact sensor 372. Contact sensor 372 transmits a signal to controller 2, and electric push rod 38 stops working.Then, the electric push rod 39 operates, and its telescopic shaft drives the sliding plate 36 to move up and down along the fixed rod 34 until the photoelectric sensor 371 detects the presence of the slurry pump within its detection range. The photoelectric sensor 371 then transmits a signal to the controller 2, and the electric push rod 39 stops operating. Simultaneously, the electric push rod 38 operates, causing the movable plate 32 to move the nozzle 7 upwards, and the connecting rod 35 moves accordingly. When the upper rubber protrusion 373 contacts the sensing surface of the upper contact sensor 372, the electric push rod 38 changes its operating mode, and the movable plate 32 moves the nozzle 7 downwards. When the lower rubber protrusion 373 contacts the sensing surface of the lower contact sensor 372 again, the electric push rod 38 changes its operating mode again.

[0024] The working principle of the painting device for slurry pump processing provided by this utility model is as follows: An external hot air blower is connected to the interior of the painting chamber 1 through an air inlet pipe. Then, the switch door on the front side of the painting chamber 1 is opened. The flange at the bottom of the slurry pump is fixed to the positioning plate 92 through the threaded positioning hole 93 using fixing bolts. The detection distance of the photoelectric sensor 371 is adjusted. Then, the switch door is closed. Under the control of the controller 2, the electric push rod 38 operates. The telescopic shaft of the electric push rod 38 drives the movable plate 32 to move downward along the limit rod 31. The process continues until the lower rubber protrusion 373 contacts the sensing surface of the lower contact sensor 372. The contact sensor 372 transmits a signal to the controller 2, and the electric push rod 1 38 stops working. Then, the electric push rod 2 39 operates, and its telescopic shaft drives the sliding plate 36 to move up and down along the fixed rod 34 until the photoelectric sensor 371 detects the presence of the slurry pump within its detection range. The photoelectric sensor 371 transmits a signal to the controller 2, and the electric push rod 2 39 stops working. Then, under the control of the controller 2, the paint pump 6 operates. Paint pump 6 transports paint from paint tank 4 to nozzle 7 via conveying pipe 5. Paint is sprayed from nozzle 7 onto the right side of slurry pump. The presence of the corrugated steel wire pipe 8 makes conveying pipe 5 more flexible. Simultaneously, electric actuator 38 operates, causing movable plate 32 to move nozzle 7 upwards, and connecting rod 35 moves accordingly. When the upper rubber protrusion 373 contacts the sensing surface of the upper contact sensor 372, electric actuator 38 changes its operating mode, and movable plate 32 moves nozzle 7 downwards. When the lower rubber protrusion 373 contacts the sensing surface of the upper contact sensor 372, electric actuator 38 changes its operating mode, and movable plate 32 moves nozzle 7 downwards. When the contact surface of the contact sensor 372 on the lower side comes into contact again, the electric push rod 38 changes its working mode again. At this time, the output shaft of the motor 94 drives the positioning plate 92 to rotate 90 degrees through the rotating shaft 91, causing the slurry pump to rotate 90 degrees. Due to the presence of the ball bearing 95 and the annular groove 96, the friction is reduced, making the rotation of the positioning plate 92 smoother. Through the up and down movement of the nozzle 7 and the rotation of the slurry pump, the slurry pump is painted. After the painting is completed, the external hot air blower provides hot air to the paint booth 1 to dry the painted slurry pump.

[0025] It is worth noting that the controller 2 disclosed in the above embodiments can be an STM32 series, the photoelectric sensor 371 can be an E3ZG-LS series, the contact sensor 372 can be a SAYL101Y, the paint pump 6 can be an NCB series rotor pump, and the motor 94 can be a NEMA11 stepper motor. The controller 2 controls the operation of the photoelectric sensor 371, the contact sensor 372, the electric actuator 1 38, the electric actuator 2 39, the paint pump 6, and the motor 94 using methods commonly used in the prior art.
