Technical Field

[0001] This utility model relates to the field of ash mixer technology, specifically to a dustproof and enclosed structure for the mechanical chamber of an ash mixer. Background Technology

[0002] A cement mixer uses a mixing mechanism to mix building materials such as cement. Since cement and other materials are in powder form, a large amount of dust is generated when mixing them. Currently, many cement mixers are open-type structures, resulting in a working environment filled with a large amount of dust. This can easily cause workers to inhale excessive dust, leading to health problems.

[0003] Although dust collection structures are currently designed for mixing devices, the large amount of dust drawn in can easily clog the filter screen. If it is not cleaned in time, the dust collection structure will not achieve the intended effect. Currently, cleaning and replacing the filter screen is cumbersome, time-consuming and labor-intensive, and cannot guarantee the efficient mixing of raw materials by the ash mixer. Therefore, it is urgent to design a dustproof and enclosed structure for the mechanical chamber of the ash mixer to solve the above problems. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-5As shown in the figure, the present invention provides a dustproof sealing structure for the mechanical chamber of an ash mixer, including a dust collection hood 1 installed above the ash mixer. A dust collection pipe 2 is provided on the top of the dust collection hood 1, which is used at least to collect the dust generated by the ash mixer through the dust collection hood 1. A fan 4 is connected to the bottom end of the dust collection pipe 2. A filter assembly 5 is provided on the outside of the end of the dust collection pipe 2 near the fan 4. A housing 59 is provided on the outside of the filter assembly 5, which is used at least to seal the outside of the filter assembly 5. A locking module 8 is provided on one side of the filter assembly 5. A high-pressure cleaning module 6 is provided on the top side of the filter assembly 5, which is used at least to clean the filter assembly 5. A shifting mechanism 7 is provided on the top of the filter assembly 5 and fixed to the outer wall of one side of the dust collection pipe 2, which is used at least to rotate the filter assembly 5.

[0032] In this embodiment, a dust collection hood 1 is installed above the ash mixer. The dust collection hood 1 can be designed according to the shape of the ash mixer to cover and seal the top of the ash mixer, thereby better collecting dust.

[0033] Specifically, the dust collection hood 1 is externally fixed with a fixing plate 11, and the dust collection hood 1 is fixed to the ash mixer by the fixing plate 11 and bolts.

[0034] In this embodiment, a dust collection pipe 2 is provided on the top of the dust collection hood 1. The dust collection pipe 2 is used at least to collect the dust generated by the dust mixer through the dust collection hood 1.

[0035] Specifically, the vacuum cleaner fitting 2 includes an upper suction pipe 21 connected to the dust collection hood 1 and a lower suction pipe 22 connected to the exhaust fan 4. A certain gap is left between the upper suction pipe 21 and the lower suction pipe 22, so that the filter assembly 5 can be rotatably inserted into the gap. The filter assembly 5 forms a sealed connection with the upper suction pipe 21 and the lower suction pipe 22, ensuring the suction power of the vacuum cleaner fitting 2.

[0036] Specifically, several support frames 3 are fixedly installed between the upper air intake pipe 21 and the lower air intake pipe 22, which serve to reinforce the upper air intake pipe 21 and the lower air intake pipe 22.

[0037] In this embodiment, the bottom end of the suction pipe 2 is connected to the exhaust fan 4, and the outer side of the end of the suction pipe 2 near the exhaust fan 4 is provided with a filter assembly 5. The exhaust fan 4 generates suction, so that the suction pipe 2 can suck and transport the dust inside the dust collection hood 1.

[0038] Specifically, the filter assembly 5 includes a rotating disk 51 located on one side of the suction pipe 2. The top two sides of the rotating disk 51 are provided with mounting grooves 52. The inner walls of the mounting grooves 52 are provided with slots 53. The mounting grooves 52 are fitted with clamps 54. The mounting grooves 52 are provided with filter discs 55 located below the clamps 54. By rotating the rotating disk 51 180 degrees, the two filter discs 55 can be swapped, so that one filter disc 55 can be used to filter dust while the other filter disc 55 is cleaned.

[0039] Specifically, a rotating shaft 56 is provided on both outer walls of the filter disc 55, and the two ends of the rotating shaft 56 are respectively located inside the slot 53. The bottom two outer walls of the clamp 54 are provided with through grooves 58 for installing the rotating shaft 56. The filter disc 55 is installed inside the mounting groove 52, and the rotating shaft 56 is engaged between the slot 53 and the through groove 58, so that the filter disc 55 can rotate inside the clamp 54. When the filter disc 55 is used to filter the inside of the dust suction pipe 2, the rotation of the filter disc 55 can be locked by the locking module 8. When the high-pressure cleaning module 6 is used to clean the filter disc 55, the rotating filter disc 55 design is more conducive to its efficient cleaning.

[0040] In this embodiment, a housing 59 is provided on the outside of the filter assembly 5, and the housing 59 is used at least for sealing the outside of the filter assembly 5;

[0041] Specifically, the housing 59 is composed of a shield 591 located outside the rotating disk 51, an upper sealing plate 592 located above the shield 591, and a lower sealing plate 593 located below the shield 591. A discharge hopper 60 is provided on one side of the bottom of the lower sealing plate 593. The shield 591, the upper sealing plate 592, and the lower sealing plate 593 are used to seal the filter assembly 5.

[0042] In this embodiment, a locking module 8 is provided on one side of the filter assembly 5;

[0043] Specifically, the locking module 8 includes an energized coil 81 fixed on the side wall of the rotating disk 51, and a plug rod 82 is provided on one side of the energized coil 81. An insertion hole 83 is provided on the outer wall of one side of the rotating disk 51. The plug rod 82 is slidably inserted into the inside of the insertion hole 83. A notch 57 is provided on the outer wall of one side of the filter disk 55. One end of the plug rod 82 is engaged in the inside of the notch 57. When the energized coil 81 is activated, the energized coil 81 drives the plug rod 82 to move inside the insertion hole 83, so that one end of the plug rod 82 is inserted into the inside of the notch 57, thereby limiting the filter disk 55 inside the mounting groove 52 using the plug rod 82.

[0044] Because the high-pressure nozzles are designed to open and close independently, the filter disc 55 can rotate when the high-pressure nozzles are biased to flush the filter disc 55. Several high-pressure nozzles can be opened simultaneously, or a single high-pressure nozzle can be opened by biasing. When the filter disc 55 rotates, the locking module 8 is activated to stop the filter disc 55 from rotating and to make it horizontally located inside the mounting groove 52. After the rotating disc 51 is repositioned by the switching mechanism 7, the filter disc 55 is used to intercept and filter the dust inside the dust suction pipe 2.

[0045] In this embodiment, a high-pressure cleaning module 6 is provided on one side of the top of the filter assembly 5. The high-pressure cleaning module 6 is used at least for cleaning the filter assembly 5.

[0046] Specifically, the high-pressure cleaning module 6 includes a high-pressure water pump 61. A water inlet pipe 62 is provided on one side of the top of the high-pressure water pump 61, and several independently operable high-pressure nozzles are provided at the bottom of the high-pressure water pump 61. When the high-pressure water pump 61 is started, water enters the interior of the high-pressure water pump 61 through the water inlet pipe 62 and is sprayed downwards through the high-pressure nozzles in the form of high pressure, thereby cleaning the dust on the filter disc 55.

[0047] In this embodiment, a shifting mechanism 7 is provided above the filter assembly 5 and fixed on the outer wall of one side of the suction pipe 2. The shifting mechanism 7 is used at least for rotating the filter assembly 5.

[0048] Specifically, the switching mechanism 7 includes a motor base 71 fixed on the outer wall of one side of the suction pipe 2, and a drive motor 72 is provided on the motor base 71. The output shaft at the bottom of the drive motor 72 is connected to the rotating disk 51. When it is necessary to clean the filter disc 55 inside the suction pipe 2, the rotating disk 51 is rotated to position it directly below the high-pressure cleaning module 6, so that one filter disc 55 can filter continuously while the other filter disc 55 is cleaned, thus improving the dust removal effect of the dust agitator.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
