Description

Technical Field

[0001] This utility model relates to the field of dust collection technology for sludge dryers, and in particular to a dust collection device for sludge dryers. Background Technology

[0002] Sludge is a product of wastewater treatment. It is an extremely complex heterogeneous body composed of organic fragments, bacterial cells, inorganic particles, colloids, etc. When treating sludge, it needs to be dried using a sludge dryer to reduce its water content. However, dust is generated during the sludge drying process. To prevent dust from adhering to the bottom of the sludge dryer, a dust collection device can be used to clean the dust.

[0003] The prior art patent CN220110628U discloses a dust collection device for a sludge dryer, including a sludge dryer body, a dust collector, and a dust collector. The dust collector and the dust collector are connected by a connecting pipe. When the dust collector is working, it sucks out the dust inside the sludge dryer body. A dust collection pipe assembly is installed on the front of the sludge dryer body. A filter device is connected to the dust collection pipe assembly and the dust collector via a flange. A collection box is connected to the bottom of the filter device. This utility model is equipped with a vertical inclined pipe, a vertical pipe, a horizontal inclined pipe, and a filter device. Since the vertical inclined pipe and the horizontal inclined pipe are both inclined, the water droplet-shaped sludge generated by the mixing of dust and steam moves along the inclined pipe under its own gravity and does not accumulate inside the pipe. Finally, it enters the collection box through the sewage outlet pipe for collection. This device eliminates the need for frequent pipe cleaning, reduces labor consumption, and improves the production efficiency of the sludge dryer.

[0004] However, the existing dust collection devices are connected to the sludge dryer and dust collection box through pipes. Since the equipment is exposed to the outside, regardless of the environment, the pipe connections will loosen over time, affecting subsequent use. In addition, the pipe connection structure is not perfect, and the pipe connections will rust over time, making it difficult to disassemble. To a certain extent, this affects the use of the entire equipment. Utility Model Content

[0005] To overcome the problems of existing sludge dryers and dust collection devices being connected by pipes, which are exposed to the elements for a long time, causing the pipe connections to loosen and become unstable, and the pipe connections to rust, making subsequent installation and disassembly inconvenient.

[0006] The technical solution of this utility model is as follows: a dust collection device for a sludge dryer, comprising a sludge dryer body, a plurality of evenly arranged dust collection pipes connected to the front end of the sludge dryer body, a dust collection connector fixedly connected to the lower end of the dust collection pipes, a filter device connected to one side of the dust collection connector, a collection box arranged below the filter device, a vacuum cleaner arranged on one side of the collection box, a second pipe connecting the vacuum cleaner and the collection box, and a mounting base fixedly connected to the surface of the vacuum cleaner near the second pipe, the mounting base having a slot inside, and positioning grooves on all four end faces of the mounting base. Each positioning slot has a spring fixedly connected inside, and one end of the spring is fixedly connected to a plug rod. The four end faces of the mounting base are each provided with an arc-shaped plate fixedly connected to the front and rear ends of one side surface of the vacuum cleaner. The front and rear ends of the two arc-shaped plates are movably connected to each other, and the two movable plates are movably connected to each other with a U-shaped buckle. The second pipe is fixedly sleeved with a mounting collar. The four ends of the mounting collar are fixedly connected to positioning blocks that snap into the positioning slots. The four positioning blocks are each provided with a plug hole. The four ends of the upper end face of the mounting collar are fixedly connected to L-shaped fixing plates.

[0007] Preferably, the installation of the pipeline is improved by fixing the positioning block and the positioning groove, and by inserting the rod into the insertion hole. At the same time, the fixing relationship between the U-shaped buckle and the L-shaped fixing plate enhances the stability of the pipeline connection and greatly improves the practicality of the overall pipeline and equipment connection structure.

[0008] Preferably, a water pipe is connected between the suction pipes, and a dust pipe is connected between the filter device and the collection box.

[0009] Preferably, a dust collection box is provided on the side of the vacuum cleaner away from the collection box, and a first pipe connects the dust collection box to the vacuum cleaner.

[0010] Preferably, the front face of the vacuum cleaner is equipped with a display screen, and on one side of the display screen are multiple evenly arranged control buttons.

[0011] Preferably, the inner wall of the mounting base is provided with a sealing groove, and a sealing ring is fixedly connected to the other side of the mounting collar away from the L-shaped fixing plate, and the sealing ring is inserted into the sealing groove.

[0012] Preferably, a first short axis is movably connected between the two curved plates and the two movable plates, and a second short axis is movably connected between the two movable plates and the U-shaped buckle.

[0013] Preferably, the U-shaped buckle is fitted onto the outside of the L-shaped fixing plate, and the insertion rod is inserted into the insertion hole.

[0014] The beneficial effects of this utility model are:

[0015] The dust collection device of this sludge dryer works by inserting a second pipe into a slot. At the same time, the mounting collar fixed to the outside of the second pipe is located on the surface of the mounting base, and the positioning blocks of the four ends of the mounting base are locked into the positioning grooves opened on the four ends of the mounting base. The insertion rod is also inserted into the insertion hole inside the positioning block. By pulling the movable plate, the U-shaped buckle is folded over. Under the action of the movement of the second short shaft, the U-shaped buckle is folded to one side, so that the U-shaped buckle is fixed to the outside of the L-shaped fixing plate. Thus, the connection structure between the pipe and the equipment is strengthened by force. At the same time, its installation method is relatively simple and convenient, preventing long-term exposure and loosening of the connection. Attached Figure Description

Springs 21 are fixedly connected inside each of the components 9. One end of each spring 21 is fixedly connected to a rod 20. Each of the four end faces of the mounting base 11 has an arc-shaped plate 14 fixedly connected to the front and rear ends of one side surface of the vacuum cleaner 6. Movable plates 16 are movably connected between the front and rear ends of two arc-shaped plates 14. U-shaped buckles 18 are movably connected between two movable plates 16. A mounting collar 10 is fixedly sleeved on the outside of the second pipe 9. Positioning blocks 22, which snap into the positioning grooves 19, are fixedly connected to the four ends of the mounting collar 10. Each of the four positioning blocks 22 has an insertion hole 24 inside. L-shaped fixing plates 23 are fixedly connected to the four ends of the upper surface of the mounting collar 10. Figure 1 As shown, the device includes a sludge dryer body 1 and a vacuum cleaner 6. In this application, the structure of the sludge dryer body 1 and the vacuum cleaner 6 is a prior art solution. The applicant will not provide a detailed description of the internal structure and components or their connection relationships of the sludge dryer body 1 and the vacuum cleaner 6. Therefore, the above-mentioned structure and connection relationships are all prior art. The applicant has not made any improvements to the components inside the handle.

[0024] Please see Figures 1-2 In this embodiment, a water pipe is connected through the suction pipes 2, a dust pipe is connected between the filter device 4 and the collection box 5, and a dust collection box 7 is provided on the other side of the vacuum cleaner 6 away from the collection box 5. A first pipe 8 is connected between the dust collection box 7 and the vacuum cleaner 6. A display screen is provided on the front face of the vacuum cleaner 6, and a number of evenly arranged control buttons are provided on one side of the display screen. By aligning the second pipe 9 with the slot 13 of the mounting base 11 on one side of the vacuum cleaner 6 and inserting it, the sealing ring 25 is locked into the sealing groove 12 opened inside for sealing. At the same time, the mounting collar 10 fixedly sleeved on the outside of the second pipe 9 is located on the surface of the mounting base 11, and the positioning blocks 22 of the four ends are locked into the positioning grooves 19 opened on the four ends of the mounting base 11 for fixing.

[0025] Please see Figures 3-5In this embodiment, a sealing groove 12 is provided on the inner wall of the mounting base 11. A sealing ring 25 is fixedly connected to the mounting collar 10 on the other side away from the L-shaped fixing plate 23. The sealing ring 25 is inserted into the sealing groove 12 to enhance the sealing effect between the pipe and the equipment and prevent it from falling off. The sealing ring 25 is made of rubber. A first short shaft 15 is movably connected between the two arc-shaped plates 14 and the two movable plates 16. A second short shaft 17 is movably connected between the two movable plates 16 and the U-shaped buckle 18. The U-shaped buckle 18 is sleeved on the L-shaped... The outside of the fixing plate 23, the insertion rod 20 is inserted into the insertion hole 24. The insertion rod 20 inside is inserted into the insertion hole 24 opened inside the positioning block 22 for reinforcement. By pulling the movable plate 16, it is folded to one side, which at the same time drives the U-shaped buckle 18 to fold. Under the action of the second short shaft 17, the U-shaped buckle 18 is folded to one side, so that the L-shaped fixing plate 23 is fixed in the U-shaped buckle 18. This strengthens the connection between pipes, and its installation method is relatively simple and convenient, thereby improving the overall practicality.

[0026] During operation, the second pipe 9 is aligned with the slot 13 of the mounting base 11 on one side of the vacuum cleaner 6 and inserted.

Simultaneously, the mounting collar 10 fixedly sleeved on the outside of the second pipe 9 is located on the surface of the mounting base 11, and the positioning blocks 22 at the four ends of the mounting base 11 are engaged in the positioning grooves 19 at the four ends of the mounting base 11 for fixation. At the same time, the insert rod 20 inside the positioning block 22 is inserted into the insertion hole 24 inside the positioning block 22 for reinforcement. By pulling the movable plate 16, it is folded to one side, which at the same time drives the U-shaped buckle 18 to fold. Under the action of the second short shaft 17, the U-shaped buckle 18 is folded to one side, so that the L-shaped fixing plate 23 is engaged in the U-shaped buckle 18 for fixation. This strengthens the connection between the pipes, and the installation method is relatively simple and convenient, thereby improving the overall practicality.

[0027] Through the above steps, the second pipe 9 is inserted into the slot 13. At the same time, the mounting collar 10 fixedly sleeved on the outside of the second pipe 9 is located on the surface of the mounting base 11, and the positioning blocks 22 of the four ends are inserted into the positioning grooves 19 opened on the four ends of the mounting base 11 for fixation. The insertion rod 20 is also inserted into the insertion hole 24 inside the positioning block 22. This solves the problem that the existing sludge dryer and dust collection device are connected by pipes. Long-term exposure to the outside will cause the pipe connection to loosen and become unstable. In addition, the pipe connection will rust, which will make subsequent installation and disassembly inconvenient.
