Description

Technical Field

[0001] The utility model relates to the technical field of calcium powder processing equipment, in particular to a calcium powder collection device. Background Technique

[0002] Calcium powder, commonly known as limestone and stone powder, is needed in industries such as rubber, plastics, paints, water-based coatings, and construction. It is a common substance on the earth. During the production process of calcium powder, a large amount of particulate dust and sundries will be generated. Therefore, after the raw materials are crushed, calcium powder needs to be screened before collection. The traditional dust filtration and collection box is relatively complex when distinguishing powders, and it cannot effectively distinguish dust and particles, resulting in low work efficiency. Therefore, in the patent document with the publication number of CN216225449U, a calcium carbonate powder screening device is disclosed. The motor drives the semi-gear to rotate, and through the meshing and separation between the semi-gear and the rack, the reciprocating movement of the moving frame is driven, so as to form a screening effect. However, when the gear rotates, during the continuous meshing and separation process, the tooth surfaces constantly impact, which is extremely easy to cause wear and affect the overall service life of the equipment. And the screening frame is a slope surface. During the reciprocating movement of the moving frame, some small particles of calcium powder are very easy to fall from the left side of the screening frame quickly under the action of inertia and the slope, resulting in the omission of calcium powder screening and affecting the screening effect. And the screened calcium powder falls into the collection box on the left side, and then the calcium powder in the collection box is transferred. The collection box has a small volume and needs to be removed and cleaned one by one, which is rather troublesome.

[0003] Therefore, the utility model provides a calcium powder collection device to improve the screening quality and save the labor burden of collection. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and a calcium powder collection device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A calcium powder collection device, comprising a housing, an upper hopper is provided at the upper end of the housing, a plurality of sieve plates are vertically spaced below the upper hopper in the housing, the sieve plates are slidably engaged with the housing left and right, the sieve holes of several sieve plates gradually decrease from top to bottom, a first slot frame is inserted at the right end of all sieve plates, a seesaw is fixedly connected to the opposite side of adjacent two first slot frames and rotatably installed on the inner wall of the housing, a second slot frame is fixed at the other end of the seesaw, a driving rod slidably installed on the inner wall of the housing left and right is commonly inserted between adjacent two second slot frames, a connecting rod is rotatably connected to the center of the driving rod, the other end of the connecting rod is rotatably connected to a driving disc, the driving disc is driven by a motor fixed on the housing, and the connecting rod and the driving disc are not coaxially connected; the bottom wall of the housing is provided with a slope inclined to the lower left, a diversion plate inclined to the lower left is provided at the left side of the housing at the left end of all sieve plates, and a blanking bin is communicated with the ends of all diversion plates and the slope;

[0008] Preferably, chutes corresponding to the sieve plates one by one are provided in the housing, an arc-shaped groove inclined to the upper right is communicated with the right side of each chute, and two round rods are provided at the left and right ends of the front and rear side walls of the sieve plate, and the round rods are inserted into the chutes.

[0009] Preferably, insertion rods are provided at the upper and lower ends of the right end of the sieve plate and the driving rod.

[0010] Preferably, the diversion plate is a mesh plate, and the diameter of the mesh holes on the mesh plate corresponds to the diameter of the sieve holes of the corresponding sieve plate.

[0011] Preferably, a guide plate inclined to the lower right is provided between the left end of the sieve plate and the upper adjacent diversion plate.

[0012] Preferably, the ends of the blanking bins are arranged staggeredly from top to bottom.

[0013] Preferably, the lengths of the plurality of sieve plates gradually increase from top to bottom.

[0014] Preferably, a baffle cloth is commonly connected between the right ends of adjacent two sieve plates.

[0015] Preferably, a convex pillow is provided at the left side of the upper end of each sieve plate.

[0016] Preferably, the dust collection assembly includes a long strip-shaped air duct embedded in the rear side wall of the housing, a suction fan is provided in the air duct, one end of the air duct outside the housing is a closed end, a collection box is detachably installed at the closed end, and a filter box is provided at the pipe orifice of the end of the air duct extending into the housing.

[0017] Compared with the prior art, the present utility model provides a calcium powder collection device, which has the following beneficial effects:

[0018] 1. The motor drives the driving disk to rotate, and drives the driving rod to slide back and forth left and right through the connecting rod, and then drives the screen plate to move back and forth left and right. Under the action of inertia, the calcium powder particles fall from the left side of the screen plate and fall to the outside of the shell through the discharge port of the lower hopper. Since the sieve holes of the screen plate gradually decrease from top to bottom, the calcium powder is distinguished according to the particle size, and the calcium powder is collected by particle classification. Moreover, all the screen plates are driven by the same motor and opened and closed synchronously. Compared with the background technology mentioned that the reciprocating engagement and separation of the half gears will cause tooth surface damage, when the tooth surfaces are in contact, the operating state of the screen plate changes suddenly and causes the screen plate to shake. This device has less wear and more stable operation.

[0019] 2. A dust collection assembly is provided on the rear side wall of the shell under each sieve plate. During screening, the exhaust fan starts and sucks out of the shell, sucking the dust away through the air duct and then falling into the collection box. The filter box prevents calcium powder particles from being sucked into the air duct, thus completing the dust collection operation, which is simple and quick.

[0020] 3. Each chute is connected to an arc groove facing the upper right on the right side. The size of the arc groove corresponds to the round rod. When the screen plate moves to the right, the round rod on the right side moves upward along the arc groove, causing the right side of the screen plate to tilt up and the screen plate to tilt toward the lower left. Under the action of inertia, the calcium powder particles are prompted to move left to achieve separation.

[0021] 4. A convex pillow is provided on the left side of the upper end of each sieve plate to slow down the movement of calcium powder when it moves to the left end of the sieve plate, avoiding the calcium powder moving too fast and sticking to some small particles of calcium powder and separating from the left end of the sieve plate, thereby improving the uniformity of calcium powder screening.

[0022] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present invention.

Specific implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the attached Figures 1-5 drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1, in order to solve the problems existing in the prior art, the present embodiment provides a calcium powder collecting device, including a shell 1, an upper hopper 2 is provided at the upper end of the shell 1, a plurality of chutes are vertically spaced apart on the inner walls on both the front and rear sides of the shell 1 below the upper hopper 2, two round rods are inserted into each chute at intervals on the left and right, and a sieve plate 3 is fixedly connected to the four round rods in the same horizontal plane, that is, a plurality of sieve plates 3 are vertically spaced apart in the shell 1, in the present embodiment, two groups of sieve plates 3 are provided, a plurality of sieve holes are evenly distributed on the surface of the sieve plates 3, the sieve plates 3 and the shell 1 slide left and right in cooperation, the sieve holes of the plurality of sieve plates 3 gradually decrease from top to bottom, a motor is fixedly installed on the right side of the sieve plate 3 in the shell 1, and the motor A driving disk 4 is fixedly installed on the output shaft, and a connecting rod 5 is rotatably connected to the end face of the driving disk 4 non-coaxially. The other end of the connecting rod 5 is rotatably connected to a vertical driving rod 6. The driving rod 6 is slidably installed on the inner wall of the shell 1 left and right. A first plug rod is fixed to both upper and lower ends of the driving rod 6. A seesaw 8 is rotatably installed on the inner wall of the shell 1 at both upper and lower ends of the driving rod 6. A first slot frame 7 is fixed to the side of the seesaw 8 facing the driving rod 6. The first plug rod is inserted into the straight slot of the first slot frame 7. A second slot frame 9 is fixed to the side of the seesaw 8 away from the driving rod 6. A second plug rod is inserted into the second slot frame 9. The second plug rod is fixedly connected to the corresponding sieve plate 3. The bottom wall of the shell 1 is provided with a slope inclined toward the lower left. The left side of the shell 1 is located at A guide plate 10 inclined toward the lower left is provided at the left end of all the sieve plates 3, and a lower bin 11 is connected to all the guide plates 10 and the end of the slope; when the calcium powder is poured into the shell 1 from the upper hopper 2, the calcium powder falls onto the uppermost sieve plate 3, the motor drives the driving disk 4 to rotate, and drives the driving rod 6 to slide back and forth left and right through the connecting rod 5, forming a crank slider mechanism, because the seesaw 8 is connected with the first plug rod and the driving rod 6 through the first slot frame 7, when the driving rod 6 slides back and forth left and right, the seesaw 8 deflects synchronously, and then drives the sieve plate 3 to move back and forth left and right through the second slot frame 9 and the second plug rod, and under the action of inertia, the calcium powder particles fall from the left side of the sieve plate 3 onto the guide plate 10, and then follow the guide plate 10 to move back and forth. The flow plate 10 enters the lower material bin 11 and falls to the outside of the shell 1 through the discharge port of the lower material bin 11. A collecting device can be hung below the lower material bin 11, which has a larger capacity and does not require frequent replacement or cleaning. The ends of the lower material bin 11 are staggered from top to bottom, and the various levels do not interfere with each other during material discharge. Since the sieve holes of the sieve plate 3 gradually decrease from top to bottom, the calcium powder is distinguished according to the particle size, and all the sieve plates 3 are driven by the same motor and opened and closed synchronously. Compared with the background technology mentioned that the reciprocating engagement and separation of the half gears will cause tooth surface damage, when the tooth surfaces are in contact, the operating state of the sieve plate 3 changes abruptly, causing the sieve plate 3 to shake. The device has less wear and more stable operation.

[0031] A dust collection assembly is provided on the rear side wall of the shell 1 below each sieve plate 3. The dust collection assembly includes a long air duct 13 embedded in the rear side wall of the shell 1. The movement range of the sieve plate 3 is always within the range of the air duct 13. An exhaust fan 14 is provided in the air duct 13. The air duct 13 is located at one end outside the shell 1 and is closed. A collection box is detachably installed at the closed end. A filter box is provided at the pipe opening at one end of the air duct 13 extending into the shell 1. When the exhaust fan 14 is started, it sucks outside the shell 1, and the dust is sucked away through the air duct 13 and then falls into the collection box. The filter box prevents calcium powder particles from being sucked into the air duct. In this way, the dust collection operation is completed simply and quickly.

[0032] In this embodiment, if the number of sieve plates 3 is greater than or equal to three, except for the seesaw 8 directly connected to the driving rod 6, two adjacent seesaws 8 among the remaining seesaws 8 are connected by a structure similar to the first insertion rod and the first slot frame 7, so that all the sieve plates 3 move synchronously.

[0033] In Example 2, each chute is connected to an arc groove facing the upper right on the right side, and the size of the arc groove corresponds to the round rod, so that when the sieve plate 3 moves left and right, when the sieve plate 3 moves right, the round rod on the right side moves upward along the arc groove, so that the right side of the sieve plate 3 is tilted, and the sieve plate 3 is tilted toward the lower left. Under the action of inertia, the calcium powder particles are prompted to move left to achieve separation.

[0034] Embodiment 3. In this embodiment, the lower hopper is arranged above the right end of the sieve plate 3. In this way, when loading, the calcium powder falls to the right side of the sieve plate 3. In this way, during the screening process, the calcium powder particles gradually move from right to left, so that the sieve hole area of ​​the sieve plate 3 is fully utilized, the calcium powder is spread more evenly, and the screening is more sufficient. A convex pillow is provided on the left side of the upper end of each sieve plate 3 to slow down the movement speed of the calcium powder when it moves to the left end of the sieve plate 3, thereby avoiding the calcium powder moving too fast and sticking to some small particles of calcium powder and separating from the left end of the sieve plate 3, thereby improving the uniformity of calcium powder screening.

[0035] In Example 4, the guide plate 10 is tilted and faces the lower left side of the sieve plate 3. During the screening process, it is inevitable that small particles of calcium powder will fall due to inertia. Therefore, in this embodiment, the guide plate 10 is set as a mesh plate. The mesh diameter on the mesh plate corresponds to the mesh diameter of the corresponding sieve plate 3. A guide plate 12 tilted toward the lower right is provided between the left end of the sieve plate 3 and the adjacent guide plate 10 above. When the calcium powder particles fall onto the guide plate 10, the small particles of calcium powder fall onto the guide plate 12 along the mesh on the guide plate 10 again, and fall onto the lower sieve plate 3 along the guide plate 12, so that the calcium powder can be more evenly separated according to particle size.

[0036] Embodiment 5: The lengths of the multiple sieve plates 3 gradually increase from top to bottom and the widths are equal. The front and rear sides of the sieve plates 3 are in contact with the inner walls of the front and rear sides of the housing 1, so that the calcium powder sifted by the upper sieve plate 3 can all fall onto the lower sieve plate 3. Moreover, a baffle cloth 15 is commonly connected between the right ends of two adjacent sieve plates 3 to prevent the calcium powder from scattering from the right side. The baffle cloth 15 is flexible and does not prevent the adjacent sieve plates 3 from moving.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
