Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for processing electric heating pipes. Background Art

[0002] The electric heating tube spraying device is a device specially designed for coating the surface of the electric heating tube with special coatings or insulating materials. During the production and processing of the electric heating tube, its surface needs to be coated. The existing spraying device for electric heating tube processing is not convenient for disassembling the nozzle, and the existing spraying device is not convenient for maintaining the nozzle. The nozzle disassembly process is time-consuming and labor-intensive, which greatly increases the workload of the staff, and is also not convenient for cleaning the recovered solution. The solution causes the recovered solution to remain inside the spraying device, which brings great inconvenience to the user.

[0003] In response to the above problems, the "A new type of spray device for processing electric heating tubes" with Chinese publication number: CN210474399U can facilitate disassembly of the spray nozzle while ensuring that it is firmly installed through the arrangement of connecting tubes, limit plates, pull rods, movable plates, springs, card plates, card slots, recovery boxes, removal outlets, fixed blocks, fixed rotating shafts and baffles, so that it is convenient for staff to maintain the spray nozzle, thereby ensuring that the spray device has a better spraying effect and reducing the workload of the staff. At the same time, it is also convenient for the staff to take out the recovery box and to clean the recovery box thoroughly to avoid the recovery solution remaining inside the recovery box to avoid contaminating the next recovery solution. The reinforcement rod is arranged to reinforce the spray shell to prevent the spray shell from tilting due to gravity or other external forces.

[0004] However, this type of spray device still has certain defects when in use. For example, when this type of spray device is used for a long time, it is necessary to always pay attention to the recovery of the spray liquid in the recovery box.

In addition, when the existing spray device is in use, solid particles, impurities or condensates may exist in the paint. These substances are easy to gather in the nozzle and clog the nozzle, thereby causing the internal pressure of the equipment to increase, resulting in damage to the pump. Utility Model Content

[0029] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Secondly, through the setting of the pressure relief component, when the nozzle 302 is blocked, the pressure inside the spray box 3 can be relieved in time, and the spray liquid inside the spray box 3 can be returned to the spray liquid storage tank 101 to prevent the spray box 3 and the pump 102 from being damaged due to excessive internal pressure. At the same time, the buzzer 402 can be used to alert the user that the nozzle 302 is working abnormally.

[0034] Example 2

[0035] On the basis of Example 1, the recovery component includes: two plugging cavities 205 opened inside the recovery box 2, one side of the inner wall of the two plugging cavities 205 is provided with a drain hole 208, the two plugging cavities 205 are provided with a sealing rubber block 207, two support rods 106 are provided inside the spray box 1, one side of the two plugging cavities 205 is provided with a loop pipe a209, and one end of the two loop pipes a209 is connected to the spray liquid storage box 101; a plurality of limiting holes 105 opened inside the spray box 1, and the bottom of the recovery box 2 is provided with a limiting hole 105. 05 corresponding number of limiting rods 203, and the bottom ends of the plurality of limiting rods 203 respectively extend into the limiting holes 105, and the outer sides of the plurality of limiting rods 203 are sleeved with springs 204; two support plates 201 are arranged inside the recycling box 2, and a filter screen 202 is arranged inside the recycling box 2, and the filter screen 202 is located on the top of the two support plates 201; one side of the two sealing rubber blocks 207 is fixedly connected to the limiting plate 206, and the top ends of the two support rods 106 respectively extend into the sealing cavity 205, and are fixedly connected to the two limiting plates 206 respectively.

[0036] When in use, the user can clamp the electric heating tube through the clamping block inside the spray box 1, and then start the pump 102 to extract the spray liquid in the spray liquid storage box 101, so that the spray liquid passes through the liquid extraction pipe 104 and the guide pipe 103, enters the spray box 3, and then enters the multiple nozzles 302 through multiple connecting water pipes 301, and is sprayed onto the electric heating tube from the multiple nozzles 302. At this time, the spray liquid that does not adhere to the electric heating tube will fall into the recovery box 2 and be filtered by the filter net 202 inside the recovery box 2. As the spray liquid in the recovery box 2 accumulates, The recovery box 2 and the spray liquid inside it will squeeze the multiple springs 204 at the bottom of the recovery box 2, causing the limiting rod 203 at the bottom of the recovery box 2 to move downward along the limiting hole 105.
