DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 8 , a technical solution provided by the utility model:

[0033] A gypsum board production dust removal device comprises a base frame 1 and a box body 2 connected to each other, wherein four pillars are arranged on the base frame 1, and the box body 2 is raised. A dust suction mechanism 4 is arranged on the base frame 1, and a filtering mechanism 3 is arranged in the box body 2. The dust suction mechanism 4 cooperates with the filtering mechanism 3 to remove gypsum dust in the gypsum board production workshop.

[0034] Specifically, the filtering mechanism 3 in this embodiment includes a lower pressing plate 31, the bottom surface of which is in contact with the inner bottom wall of the box body 2, and one side of the lower pressing plate 31 is fixedly connected to a frame body 32. A guide rod 34 is fixedly connected to the top of the lower pressing plate 31, and an upper pressing plate 35 is slidably connected to the surface of the guide rod 34, wherein there are four guide rods 34, which are distributed at four diagonal positions of the lower pressing plate 31, so that the movement of the upper pressing plate 35 is more stable, and the upper pressing plate 35 can cooperate with the lower pressing plate 31 after moving downward to press the gypsum dust in the box body 2 into a powder cake, which is convenient for collecting and cleaning the dust. A filter plate 33 is inserted into the frame body 32, and one side of the filter plate 33 is in contact with the surface of the upper pressing plate 35, so that the upper pressing plate 35 can scrape off the dust attached to the surface of the filter plate 33 during the movement.

[0035] Combination Figure 6 and Figure 7 As shown, a groove 321 is provided on one side of the frame 32 close to the upper pressure plate 35 and the lower pressure plate 31, and slots 322 are connected on both sides of the groove 321. Accordingly, a side of the filter plate 33 away from the upper pressure plate 35 and the lower pressure plate 31 is fitted with the inner wall of the groove 321, and plug-in parts 332 are provided on both sides of the filter plate 33, and the plug-in parts 332 are plugged into the slots 322 to achieve a limiting effect and prevent the filter plate 33 from tilting or shifting.

[0036] Combination Figure 5 and Figure 6 As shown, a positioning groove is downwardly opened on the inner bottom wall of the groove 321, and a plurality of springs 314 are fixedly connected to the inner bottom wall of the positioning groove. The plurality of springs 314 are distributed in a straight line with equal distances along the length direction of the positioning groove. An elastic plate 313 is fixedly connected to the top of the spring 314. The bottom end of the filter plate 33 is inserted into the positioning groove and fits against the top surface of the elastic plate 313. The top of the filter plate 33 and the top of the frame 32 are both in contact with the inner top wall of the box body 2. The top of the filter plate 33 is subjected to the pressure of the inner wall of the box body 2 and shrinks into the inside of the frame body 32, thereby making the elastic plate 313 in a compressed state. When the frame body 32 is detached from the box body 2, the filter plate 33 will pop up upward under the elastic force of the spring 314, so that its top is exposed outside the frame body 32, so that the filter plate 33 is easy to be taken out of the frame body 32.

[0037] Furthermore, a slope 331 is provided at the top of the filter plate 33 , so that when the frame 32 enters the interior of the box body 2 , the top of the filter plate 33 can automatically shrink into the interior of the frame 32 under pressure.

[0038] In this embodiment, the outer wall of the frame 32 is in contact with the inner wall of the box 2 and can be pulled out from the box 2, so that the filter plate 33, the upper pressing plate 35, the lower pressing plate 31 and the pressed powder cake can be taken out of the box 2.

[0039] Specifically, a through slot is provided on the inner wall of the frame 32, and a baffle 36 is slidably connected to the inner wall of the through slot. The length of the baffle 36 is greater than the length of the through slot, and the through slot can be blocked to prevent dust inside the box 2 from escaping through the through slot. The upper and lower ends of the baffle 36 penetrate the box 2, so that the frame 32 can be restricted in the box 2. The frame 32 is separated from the box 2. A slide 23 for the baffle 36 to slide is provided at the bottom of the box 2. One end of the slide 23 is connected to the outside. When the top end of the baffle 36 is separated from the box 2, the baffle 36 and the frame 32 can be pulled out of the box 2 together.

[0040] See also Figure 8 One side of the upper pressing plate 35 is fixedly connected to the baffle 36. When the frame 32 is pulled out from the box body 2, the upper pressing plate 35 can be taken out together through the baffle 36, and then cooperate with the lower pressing plate 31 to take the gypsum powder cake out of the box body 2.

[0041] In this embodiment, the filter mechanism 3 further includes a swing arm 37, the bottom end of which is rotatably mounted on a side of the frame 32 away from the upper pressing plate 35 and the lower pressing plate 31, and a connecting plate 39 is slidably connected to the inner wall of the swing arm 37, one end of which is fixedly connected to the baffle 36, and the connecting plate 39 can slide along the length direction of the swing arm 37, so that the up and down linear motion of the baffle 36 can adapt to the angle change when the swing arm 37 rotates. Round rods 38 are fixedly connected to both sides of the connecting plate 39, and the surface of the round rod 38 is slidably connected to the inner wall of the swing arm 37, which is used to limit the connecting plate 39 and prevent the connecting plate 39 from detaching from the swing arm 37. The swing arm 37 is connected to the frame 32 by a tension spring 312, and the tension of the tension spring 312 enables the swing arm 37 to be maintained at a certain angle without external interference, so that the top of the baffle 36 can be inserted into the inner wall of the box 2, and the upper pressing plate 35 and the lower pressing plate 31 can be in an open state.

[0042] In addition, a connecting seat 310 is fixedly connected to a side of the swing arm 37 away from the baffle 36 , and a pull rod 311 is fixedly connected to the connecting seat 310 for controlling the rotation of the swing arm 37 .

[0043] Combination Figure 1 and Figure 2As shown, the dust collection mechanism 4 includes an exhaust fan 41, which is fixedly mounted on the base frame 1. The output end of the exhaust fan 41 is connected to a dust collection hood 43 through a hose 42, and the dust collection hood 43 is fixedly mounted on the inner wall of the second dust suction port. In coordination with this, a first dust suction port 21 is provided on one side of the box body 2, and a box door 22 is provided on the other side of the box body 2. The box door 22 is provided with a second dust suction port, and the dust collection mechanism 4 is connected to the second dust suction port. When in use, the dust collection mechanism 4 provides suction, so that the gypsum dust in the workshop passes through the first dust suction port 21 and the second dust suction port in sequence.

[0044] When the gypsum board production dust removal device of the utility model is used, the filter mechanism 3 is placed in the box body 2, so that the baffle 36 in the filter mechanism 3 is inserted into the inner top wall of the box body 2, and the box door 22 is closed to seal one side of the box body 2. Then, the exhaust fan 41 is started, and the exhaust fan 41 provides negative pressure to the box body 2 through the hose 42 and the dust hood 43. The air in the workshop enters the box body 2 through the second dust suction port on one side of the box body 2. After the gypsum dust in the air is filtered by the filter plate 33, the clean air enters the exhaust fan 41 through the dust hood 43 and the hose 42, and is discharged into the workshop again.

[0045] After vacuuming is completed, the vacuuming mechanism 4 is closed and the door 22 is opened. Then the pull rod 311 is pulled downward, and the pull rod 311 drives the swing arm 37 to swing outward through the connecting seat 310. The swing arm 37 drives the baffle 36 to move downward through the connecting plate 39 and the round rod 38. The baffle 36 drives the upper pressing plate 35 to move downward. During the movement, the upper pressing plate 35 can scrape the dust attached to the surface of the filter plate 33 and the inner wall of the box body 2. After the upper pressing plate 35 moves a certain distance, it can cooperate with the lower pressing plate 31 to press the gypsum dust between the two into a powder cake. Then the frame 32 is pulled outward so that the filter mechanism 3 is separated from the box body 2. When the frame 32 is completely pulled out of the box body 2, the filter plate 33 will pop up under the elastic force of the spring 314, so that its top is exposed outside the frame body 32, and then the filter plate 33 can be taken out from the top of the frame body 32, which is convenient for cleaning the gypsum powder and the filter plate 33.
