Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for grinding mills, in particular to a dust removal and filtering mechanism for Raymond grinding mills. Background Technology

[0002] Raymond mill is a mechanical equipment used for high-fine powder processing. However, when the mill is in operation, dust may be generated due to various reasons, such as equipment aging, improper operation, and poor sealing of the equipment. These conditions cause dust to be generated during the mill production, and suction equipment is required to suck and collect the dust. Usually, a fan is used in conjunction with a filter to collect the dust. The fan is used to suck the air so that the dust in the air is intercepted by the filter after passing through the filter. However, the filter is prone to clogging after intercepting the dust, which affects the airflow and is inconvenient. In addition, the dust ground from some production raw materials may have a certain odor. At the exhaust point of the fan, the surrounding air is sucked by the fan and discharged here, which may cause a strong odor here. Generally, most fans are fixed and it is difficult to adjust the fan outlet, which is inconvenient. Contents of utility model

Detailed Description of the Preferred Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 In the embodiment of the present utility model, a dust removal and filtration mechanism for a Raymond mill includes a bottom plate 100. Above the bottom plate 100, a dust removal mechanism 300 is provided, and an adjustment mechanism 200 is provided between the dust removal mechanism 300 and the bottom plate 100. The dust removal mechanism 300 is equipped with a cleaning mechanism 400;

[0023] The adjustment mechanism 200 includes two U-shaped frames 210, and U-shaped plates 220 are provided at both arms of the two U-shaped frames 210. The two arms of the two U-shaped frames 210 are located between the two arms of the adjacent U-shaped plates 220, and the two U-shaped frames 210 are respectively located at both ends of the dust removal mechanism 300. One end of the two arms of the two U-shaped plates 220 on the same U-shaped frame 210 is fixedly connected to the dust removal mechanism 300. Threaded holes 221 are opened on the inner walls of the four U-shaped plates 220, and threaded bolts 222 are screwed into the four threaded holes 221. A chute 101 is opened on the top surface of the bottom plate 100, and sliding blocks 211 are fixedly connected to the bottom surfaces of the two U-shaped frames 210. Among them, one sliding block 211 is slidably clamped inside the chute 101, and the other sliding block 211 is fixedly sleeved inside the chute 101.

[0024] Specifically, by using the dust removal mechanism 300 to suck dust, the user can adjust the height positions of both ends of the dust removal mechanism 300 on the two U-shaped frames 210 by sliding both ends of the dust removal mechanism 300, so as to adjust the orientation, inclination angle and overall height of the dust removal mechanism 300, and thus adjust the position of the air outlet of the dust removal mechanism 300, so as to facilitate the user to adjust the dust removal mechanism 300. When the user needs to fix the height position of the dust removal mechanism 300 on the U-shaped frame 210, the threaded bolt 222 can be rotated to abut against the U-shaped frame 210 for fixation. Embodiment 1

[0025] As Figures 2 - 3As shown, in this embodiment, one end of each of the plurality of screwed bolts 222 is rotatably connected to a pressing plate 223. The dust removal mechanism 300 includes a square pipe 310. At both ends of the opposite sides of the square pipe 310, a rotating plate 312 is rotatably connected. The four U-shaped plates 220 correspond to the four rotating plates 312 one by one, and one end of each arm of the four U-shaped plates 220 is fixedly connected to one side of the corresponding rotating plate 312. One end of the square pipe 310 is fixedly connected to a connecting frame 320. A fan is arranged inside the connecting frame 320. A plurality of horizontally placed fixing frames 340 are fixedly connected between the two opposite inner side walls of the square pipe 310, and all the plurality of fixing frames 340 are U-shaped. A main filter screen 341 is fixedly connected between the two arms of the plurality of fixing frames 340. A plurality of connecting holes 313 are formed in the top surface of the square pipe 310, and the plurality of connecting holes 313 correspond to the plurality of fixing frames 340 one by one. A conduit 350 is fixedly sleeved inside each of the plurality of connecting holes 313, and one end of each of the plurality of conduits 350 is fixedly connected to a spray head. All the plurality of spray heads are located at the top of one side of the corresponding fixing frame 340. At both ends inside the connecting frame 320, a secondary filter screen 321 is fixedly sleeved.

[0026] In this embodiment, the surface of the U-shaped frame 210 and the pressing plate 223 are both coated with abrasive material. When the user rotates the screwed bolt 222, the pressing plate 223 can be pressed against the surface of the U-shaped frame 210 to increase the contact area between the screwed bolt 222 and the U-shaped frame 210, improving the fixing effect on the square pipe 310. The user can start the fan to suck the dust from the other end of the square pipe 310 through the square pipe 310 and filter it by the plurality of main filter screens 341. If the dust has an odor, the user can adjust the orientation of one end of the square pipe 310 to change the orientation of the air discharged by the fan. And the user can connect the conduit 350 to a water pump to make the water flow out from the spray head through the conduit 350, so that the spray head sprays on the adjacent main filter screen 341. When there is too much dust on the main filter screen 341, the dust can be washed away by the sprayed water flow.

[0027] As Figures 2 - 3 As shown, in this embodiment, a collection box 330 is fixedly connected to the bottom surface of the square pipe 310, and a communication port 311 is formed in the bottom surface of the square pipe 310. The inside of the communication port 311 is communicated with the inside of the collection box 330. The plurality of fixing frames 340 are all located above the communication port 311. A plurality of partition plates 331 are fixedly connected to the inner bottom surface of the collection box 330, and the plurality of partition plates 331 correspond to the plurality of main filter screens 341 one by one. The top ends of the plurality of partition plates 331 all penetrate through the bottom surface of the square pipe 310 and are fixedly connected to the bottom ends of the corresponding main filter screens 341.

[0028] During specific implementation, the water flow sprayed by the spray head can flow down along the main filter screen 341 and enter the collection box 330 to be collected. And through the partition plate 331, the air flow sucked by the fan can pass through the main filter screen 341, making it difficult for the air flow sucked by the fan to enter the communication port 311 and pass through one end of the square pipe 310. Embodiment Two

[0029] On the basis of the first embodiment, the cleaning mechanism 400 is provided to further clean the main filter screen 341.

[0030] As Figures 1 - 5 shown, in this embodiment, the cleaning mechanism 400 includes a plurality of clamping strips 410, and the plurality of clamping strips 410 correspond to the plurality of fixing frames 340 one by one. The plurality of clamping strips 410 are all located on one side of the corresponding fixing frame 340. A plurality of clamping grooves 314 are opened on both opposite sides of the square pipe 310. The plurality of clamping grooves 314 on the same side of the square pipe 310 correspond to the plurality of fixing frames 340 one by one. The plurality of clamping grooves 314 on the same side of the square pipe 310 are all located at one side of the corresponding fixing frame 340. Both ends of the plurality of clamping strips 410 are slidably clamped inside two adjacent clamping grooves 314 respectively, and a brush plate 420 is fixedly connected to the bottom surface of the plurality of clamping strips 410. A moving strip 430 is arranged on one side of the square pipe 310, and one ends of the plurality of clamping strips 410 are rotatably connected to one side of the moving strip 430. A turntable 440 is arranged on the other side of the moving strip 430, and a clamping block 441 is fixedly connected to the outer ring edge of one side of the turntable 440. A moving groove 431 is opened at the center of the other side of the moving strip 430, and the clamping block 441 is slidably clamped inside the moving groove 431. One side of the square pipe 310 is fixedly connected with a motor box 442 through a mounting frame, and a driving motor is arranged inside the motor box 442. The motor shaft of the driving motor is fixedly connected to the center of the other side of the turntable 440.

[0031] During specific implementation, the clamping strip 410 can only slide in the adjacent clamping groove 314 and cannot rotate. There are bristles on one side of the brush plate 420, and the bristles are all abutted against the adjacent main filter screen 341. The bristles can be made of pig bristles. By starting the driving motor to drive the turntable 440 to rotate, the turntable 440 drives the clamping block 441 to rotate around itself, and while the clamping block 441 slides in the moving groove 431, it drives the moving strip 430 and the plurality of clamping strips 410 to move synchronously, so that the plurality of clamping strips 410 slide back and forth in the adjacent clamping grooves 314. When the spray head sprays, some dust on the main filter screen 341 may adsorb the water flow to form sludge. The main filter screen 341 is cleaned by the bristles on the brush plate 420 brushing the main filter screen 341 back and forth and cooperating with the water flow scouring, so as to avoid the blockage of the main filter screen 341. The size of the clamping groove 314 can be designed and adjusted as required, so that the dust in the air flow is not easy to fly out of the square pipe 310 through the clamping groove 314. And when the dust in the air flow moves to the main filter screen 341, it will contact the water droplets sprayed by the spray head, and the water droplets will adsorb the dust and discharge it into the collection box 330 together, further avoiding a large amount of dust from escaping from the square pipe 310 through the clamping groove 314.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0033] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
