Abstract
Description
Technical Field
[0001] The utility model relates to a cleaning spraying device, in particular to a paper machine frame cleaning spraying device, belonging to the technical field of paper machine frame cleaning. Background Art
[0002] In the papermaking industry, due to the warm and humid environment of the papermaking wet-end system, the organic components in the slurry, such as fiber, starch, protein, etc., are prone to breed bacteria and produce stickies, sediments, and rotten pulp, which will contaminate the papermaking machine frame, not only affecting the appearance, but also contaminating the papermaking felt and forming mesh, causing production obstacles. Therefore, the frame needs to be cleaned regularly, and during the cleaning process, a spray device is usually used to spray the cleaning liquid in the form of foam on the frame.
[0003] Due to the large size of the papermaking machine frame, the commonly used cleaning spraying device is a movable type. However, most mobile cleaning spraying devices do not have a stable support structure, or only have a simple limit on the moving wheel, which makes the overall stability of the mobile cleaning spraying device poor. It is easy to move on its own during the cleaning process, resulting in the inability to accurately spray the agent on the frame, which not only reduces the cleaning effect, but also causes waste of agents.
[0004] Therefore, it is urgent to improve a paper machine frame cleaning spraying device to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of the utility model is to provide a papermaking machine frame cleaning and spraying device, which can stably support the entire movable support frame through the setting of a support limiting structure, and fix the position of the movable support frame by relying on multiple support plates in contact with the ground to prevent movement during spray cleaning of the papermaking machine frame, so that the agent can be accurately sprayed on the frame, thereby improving the cleaning effect and avoiding agent waste.
[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:
[0007] The control cabinet that is located at the bottom of described movable frame is provided with the control cabinet of said liquid-gas mixing box, and the control cabinet of said liquid-gas mixing box is provided with the control cabinet of said liquid-gas mixing box.
[0008] Preferably, a limiting rod installed on the fixed plate is provided above the bidirectional screw, and a limiting block slidably connected to the limiting rod is fixedly installed on the top of the moving block.
[0009] Preferably, an air pressure regulating valve is fixedly installed on one end of the air compressor.
[0010] Preferably, a slide rail is fixedly installed on the surface of the fixed frame, an adjusting rod connected to the nozzle is slidably installed inside the slide rail, a fixing rod is fixedly installed on one side of the adjusting rod, a spring is fixedly installed on the fixing rod, a second support rod is fixedly installed on one end of the spring, the second support rod passes through the spring and a tooth block is fixedly installed on one end of the fixing rod, and a tooth plate used in conjunction with the tooth block is fixedly installed on one side of the slide rail.
[0011] Preferably, a pointer is fixedly mounted on one end of the fixing rod, and a scale plate is fixedly mounted on the surface of the sliding rail.
[0012] Preferably, a support bar is fixedly mounted on the adjusting rod, and a collection box is provided on the support bar.
[0013] Preferably, a slide groove is provided on the top of the support bar, a slide plate is fixedly installed on the bottom of the collection box, a plurality of first magnetic blocks are fixedly installed on one side of the support bar, and a plurality of second magnetic blocks are fixedly installed on one side of the collection box.
[0014] The utility model has at least the following beneficial effects:
[0015] By setting the support and limiting structure, the mobile support frame can be stably supported as a whole and moved to the vicinity of the papermaking machine frame. At the same time, the two motors are started to drive the bidirectional screws to rotate. The rotation of the bidirectional screws drives the two moving blocks to approach each other through the bidirectional threads. When the two moving blocks approach each other, the two first support rods are used to push the support plates, so that the two support plates descend and contact the ground. The position of the mobile support frame is fixed by relying on the friction force generated by the contact between the multiple support plates and the ground, preventing movement during spray cleaning of the papermaking machine frame, so that the agent can be accurately sprayed on the frame, thereby improving the cleaning effect and avoiding agent waste.

At the same time, the two motors 10 are started to drive the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 drives the two moving blocks 11 to approach each other through the bidirectional thread. When the two moving blocks 11 approach each other, the two first support rods 12 are used to push the support plate 13, so that the two support plates 13 descend and contact the ground. The friction force generated by the contact between the multiple support plates 13 and the ground is used to fix the position of the mobile support frame 1 to prevent it from moving during the spray cleaning of the papermaking machine frame, so that the agent can be accurately sprayed on the frame, thereby improving the cleaning effect and avoiding agent waste.
[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a limit rod 14 mounted on the fixed plate 8 is provided above the bidirectional screw 9, a limit block 15 slidably connected to the limit rod 14 is fixedly installed on the top of the moving block 11, an air pressure regulating valve 16 is fixedly installed at one end of the air compressor 4, a slide rail 17 is fixedly installed on the surface of the fixed frame 2, an adjusting rod 18 connected to the nozzle 6 is slidably installed inside the slide rail 17, a fixed rod 19 is fixedly installed on one side of the adjusting rod 18, a spring 20 is fixedly installed on the fixed rod 19, a second support rod 21 is fixedly installed on one end of the spring 20, the second support rod 21 passes through the spring 20 and a tooth block 22 is fixedly installed on one end of the fixed rod 19, and a tooth plate 23 used in conjunction with the tooth block 22 is fixedly installed on one side of the slide rail 17. By setting the limit rod 14 and the limit block 15, the movable block 11 can be limited when it moves, so that it can move smoothly and prevent twisting. By setting the air pressure regulating valve 16, the air pressure can be adjusted to control the speed and distance of the medicinal foam spraying. By setting the slide rail 17, the adjusting rod 18, the fixed rod 19, the spring 20, the second support rod 21, the gear block 22 and the tooth plate 23, the slide rail 17 and the adjusting rod 18 are set at the bottom of the nozzle 6.

After the adjustment is completed, the second support rod 21 is toggled so that the gear block 22 at one end is engaged with the tooth plate 23 and supported by the spring 20. When the gear block 22 and the tooth plate 23 are engaged, the adjusting rod 18 can be fixed, thereby fixing the adjustment height of the nozzle 6.

By setting the support bar 26 and the collection box 27, after stopping cleaning, a small amount of medicine will flow out of the nozzle 6, and the collection box 27 can collect the medicine to prevent the medicine from falling directly outside and causing waste. By setting the slide 28, the slide 29, the first magnetic block 30 and the second magnetic block 31, the slide 28 and the slide 29 can limit the collection box 27 after being connected, so that it can be accurately installed under the nozzle 6, and the first magnetic block 30 and the second magnetic block 31 can fix the collection box 27 after being fitted to prevent it from falling off.
[0028] In this embodiment, if Figure 1-Figure 5As shown, the working process of a paper machine frame cleaning spraying device provided in this embodiment is as follows:
[0029] Move it to the vicinity of the papermaking machine frame, and start the two motors 10 at the same time to drive the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 drives the two moving blocks 11 to approach each other through the bidirectional thread. When the two moving blocks 11 approach each other, the two first support rods 12 are used to push the support plate 13, so that the two support plates 13 descend and contact the ground.
