[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 8The present invention provides a technical solution: a dust blockage detection device, including a housing 1, an air inlet 2 and an air outlet 3 respectively opened at the upper and lower ends of the housing 1, a release channel 4 provided at the bottom end of the housing 1, a support rod 5 fixedly connected in the inner wall of the housing 1, a threaded groove opened on the outer wall of the support rod 5, an installation sleeve 6 sleeved on the outer peripheral wall of the support rod 5, and a plurality of filter plates 7 for filtering dust are arranged at equal intervals on the outer wall of the installation sleeve 6. The mounting sleeve 6 is equipped with a cleaning mechanism 8 for clearing dust blockages.

[0024] In this embodiment, as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the mounting sleeve 6 includes several support sections 61 arranged vertically at equal intervals, and each of the support sections 61 has a T-shaped rotating groove at both the upper and lower ends. A rotating sleeve 62 is rotatably connected in the rotating groove, and every two support sections 61 are connected by the rotating sleeve 62. Both the rotating sleeve 62 and the support section 61 are movably sleeved with the support rod 5. By setting the rotating sleeve 62, the support section 61 can be sealed without affecting the rotation drive cleaning brush 84 to clean the filter plate 7.

[0025] In this embodiment, as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the cleaning mechanism 8 includes a rubber sealing sleeve 81 sleeved on the outer wall of the rotating sleeve 62, and mounting holes 82 are provided at both ends of the rubber sealing sleeve 81 and the rotating sleeve 62. An installation rod 83 passes through the inner wall of the mounting hole 82. Both ends of the installation rod 83 are equipped with cleaning brushes 84, which are used to clean the filter plate 7. The other end of the installation rod 83 is fixedly connected to a sliding sleeve 85. The inner wall of the sliding sleeve 85 is threadedly engaged with the outer wall of the support rod 5. When the filter plate 7 falls, the sliding sleeve 85 moves down synchronously and rotates through the threads on the outer wall of the support rod 5, driving the cleaning brushes 84 to clean the filter plate 7.

[0026] In this embodiment, as Figure 5 , Figure 6 and Figure 8 As shown, the two cleaning brushes 84 are slidably connected to the outer peripheral wall of the mounting rod 83, and the two cleaning brushes 84 and the inner wall of the mounting rod 83 are connected by a return spring. When the cleaning brush 84 passes through the clumps of dust or the filter holes, the cleaning brush 84 moves up and down by the return spring. The return force of the return spring can keep the cleaning brush 84 in close contact with the filter plate 7, thereby increasing the cleaning effect.

[0027] In this embodiment, as Figure 6 andFigure 7 As shown, the cleaning mechanism 8 also includes several trigger plates 86 fixed on the inner wall of the support section 61. Inclined plates 87 are fixedly connected to the side walls of the trigger plates 86. Through the combination of the inclined plates 87 and the trigger plates 86, the vibration rod 810 can be driven to move back and forth, continuously generating a vibration effect and preventing dust from sticking.

[0028] In this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the cleaning mechanism 8 also includes a mounting cavity 88 opened inside the mounting rod 83. Both the upper and lower ends of the mounting cavity 88 are provided with movable grooves 89 that penetrate the outer peripheral wall of the mounting rod 83. A vibration rod 810 is slidably connected in the inner wall of the mounting cavity 88. The vibrating rod 810 has an I-shaped structure, and a buffer spring is sleeved on the outer wall of the vibrating rod 810. One end of the buffer spring is fixedly connected to the inner wall of the mounting cavity 88. Both ends of the vibration rod 810 are fixedly connected to contact rods 811. The contact rods 811 slide in contact with the trigger plate 86. When the vibration rod 810 contacts the inclined plate 87 and the trigger plate 86 and moves back and forth continuously, the vibration rod 810 swings back and forth through the buffer spring, so that the mounting rod 83 keeps vibrating and reduces the adhesion of dust.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the cleaning mechanism 8 also includes a fixing plate 812 fixed to the top wall of the housing 1, and two symmetrically arranged inclined grooves 813 are provided on the outer wall of the fixing plate 812; A spring telescopic plate 814 is also fixedly connected to the top wall of the housing 1. An active cavity 815 is opened in the inner wall of the spring telescopic plate 814. Two L-shaped trigger rods 816 are symmetrically slidably connected in the inner wall of the active cavity 815. One end of each trigger rod 816 is connected to a trigger block 817 that is slidably connected to the inclined groove 813. A support block 818 is passed through each of the two trigger rods 816. Both support blocks 818 are fixedly connected to the top of the filter plate 7. The two trigger rods 816 are connected to the inner wall of the movable cavity 815 by springs. By setting the two trigger rods 816 and the support block 818, several filter plates 7 can be suspended inside the equipment. By the weight moving down, the trigger rods 816 and the support block 818 are separated, the filter plates 7 are released from locking, and the dust accumulation is detected.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 8As shown, an electric push rod body 819 is fixedly connected to the bottom wall of the housing 1, and a support plate 820 is fixedly connected to the top of the electric push rod body 819. The support plate 820 is fixedly connected to the bottom of the filter plate 7. A compression spring is fixedly connected between the support plate 820 and the bottom of the housing 1, and the compression spring is sleeved on the support rod 5. It can push several filter plates 7 to reset through the electric push rod body. The two support blocks 818 squeeze the two trigger rods 816 to retract, so that the support blocks 818 can be reset to the initial state, and the spring resets and passes through the support blocks 818 again to hoist the filter plates 7.

[0031] In this embodiment, as Figure 2 and Figure 3 As shown, accordion-style dust covers 9 are fixedly connected to the top and bottom walls of the housing 1, and both accordion-style dust covers 9 are fixedly connected to the outer wall of the filter plate 7 to protect the electric push rod body 819 and the spring telescopic plate 814.

[0032] The computer software involved in the hardware carrier, such as the electric push rod body, in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carrier. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned hardware carrier, nor is it a key technical point of the invention.

[0033] Therefore, the "electric push rod body" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, in order to solve the corresponding technical problems to be solved by this application.

[0034] A method for clearing blockages in a dust blockage detection device includes the following steps: S1. As the airflow passes through several filter plates 7 in the housing 1, the dust in the airflow will be gradually adsorbed by the filter plates 7, purifying the airflow. The dust on the filter plates 7 will continuously accumulate and clump together. S2. As the weight of several filter plates 7 gradually increases, the support block 818 on the filter plate 7 drives the trigger rod 816 to pull the spring telescopic plate 814 downward. The spring telescopic plate 814 begins to stretch. At this time, the trigger block 817 on the two trigger rods 816 slides in the inclined groove 813, causing the two trigger rods 816 to move relative to each other, causing the trigger rod 816 to move out of the support block 818 and release the lock on the support block 818. S3. As the filter plate 7 moves downward by its weight, the entire support section 61 and the rotating sleeve 62 move downward along the support rod 5. At the same time, due to the threaded engagement between the sliding sleeve 85 and the support rod 5, the sliding sleeve 85 can rotate on the support rod 5. The sliding sleeve 85 drives the rotating sleeve 62 and the rubber sealing sleeve 81 to rotate together through the mounting rod 83, causing the cleaning brushes 84 at both ends of the mounting rod 83 to clean the filter plate 7 and break up and sweep away the clumps of dust. S4. Immediately afterward, when the mounting rod 83 rotates together, the contact rod 811 on the vibrating rod 810 contacts the inclined plate 87, the vibrating rod 810 moves backward and compresses the buffer spring, until the contact rod 811 passes through the inclined plate 87 on the trigger plate 86 and moves out, the vibrating rod 810 resets through the buffer spring and generates a vibration impact, causing the cleaning brush 84 on the mounting rod 83 to vibrate together, shaking off the dust adhering to the cleaning brush 84; S5. When the filter plate 7 finally moves to the bottom, the electric push rod body 819 pushes the filter plate 7 upward, so that the support block 818 on the filter plate 7 comes into contact with the two trigger rods 816, squeezing the two trigger rods 816 relative to each other, so that the support block 818 and the trigger rods 816 come into contact again, causing the trigger rods 816 to penetrate the support block 818 again to limit the position of the filter plate 7, waiting for the next accumulation cleaning operation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
