Description

Technical Field

[0001] This utility model relates to the field of airflow pulverizer technology, specifically to an anti-clogging airflow pulverizer feeding control device. Background Technology

[0002] An air jet mill is a device that uses high-speed airflow or superheated steam to pulverize material particles through mutual collision and friction. Its core advantages are that it does not damage heat-sensitive materials and has low pollution characteristics. At present, this technology has been widely used in the processing of superhard materials, high-purity pharmaceutical powders and heat-sensitive chemical materials.

[0003] Air jet mills often process powdery or granular materials. For granular materials, the size of the particles varies during production, and external debris may be mixed in during the bagging process, all of which can cause blockages in the feeding process of the air jet mill. In addition, differences in particle size and the presence of external debris can reduce the grinding effect. Different models of air jet mills also have different requirements for the size of the feed particles. Therefore, we propose an anti-clogging feeding control device for air jet mills. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an anti-clogging airflow pulverizer feeding control device. Driven by a drive motor and a linkage crank, the pulling block continuously pulls and pushes the main frame. Particles of the specified size fall through the round holes on the detachable screen plate into the receiving box on the lower side. Rod-shaped debris and larger particles in the material are separated on the upper side of the detachable screen plate, thus creating a continuous lateral shaking effect on the main frame. By screening out larger materials and debris, clogging can be avoided when feeding the airflow pulverizer. The detachable screen plate is installed and fixed with bolts and is easy to disassemble and replace, thus being suitable for screening different specifications of material particles and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed control device for an anti-clogging airflow pulverizer, comprising a main frame, an oscillation generating unit, and a screening and discharging unit; Main frame: It is arranged horizontally and its side section is a U-shaped structure. The main frame is inclined at a 3° angle in the horizontal direction. A transfer bucket is placed on the lower right front side of the main frame, and a hoist is installed at the position adjacent to the transfer bucket. Oscillation generating unit: installed on the left end and front and rear sides of the main frame; Screening and discharge unit: includes a receiving box, a guide block, a discharge port, a detachable screen plate, and a guide frame. The receiving box is fixedly connected to the lower end of the main frame. The receiving box is in the same direction as the main frame and has a U-shaped side cross-section. A rectangular channel connected to the receiving box is opened on the bottom inside the main frame. A guide block is fixedly connected to the rear wall on the right side of the receiving box. The guide block has a right-angled triangular structure and a discharge port facing the right front is separated at the right end of the receiving box. A detachable screen plate is fixedly installed at the upper end of the rectangular channel inside the main frame with bolts. A guide frame is installed on the right side inside the main frame. The guide frame has a 7-shaped folded structure, and its shorter end is fixed to the front inner wall of the main frame with bolts. The longer section of the guide frame's vertical plate is attached to the upper end of the detachable screen plate, and the longer section of the guide frame faces obliquely backward.

[0006] The oscillation unit drives the main frame and internal screening and receiving components to reciprocate laterally. The continuously oscillating detachable screen plate screens the material on the upper side, and particles that meet the specifications fall through the round holes on the detachable screen plate into the receiving box on the lower side. Rod-shaped impurities and larger particles in the material are separated on the upper side of the detachable screen plate. The tilt angle of the main frame, combined with its own oscillation effect, allows the material in the receiving box and on the upper side of the detachable screen plate to be conveyed to the right while shaking. The guide block causes the qualified material in the receiving box to be conveyed obliquely forward and fall into the transfer hopper, and then conveyed to the feed inlet of the air jet mill by the elevator. The guide frame installed on the upper side of the detachable screen plate allows unqualified materials and impurities to be discharged obliquely backward. By offsetting the discharge direction from the discharge direction of qualified materials, mixing during discharge is avoided. The detachable screen plate is installed and fixed with bolts and is easy to disassemble and replace, thus adapting to the screening needs of different particle sizes.

[0007] Furthermore, the oscillation generating unit also includes a guide plate and a support frame. A guide plate is fixedly connected to the upper left side of the main frame, with its lower end bent to the left. A support frame is fixedly connected to the inner corner of the guide plate, and the support frame consists of a long rod and a short rod. The guide plate can separate a material loading area on the inner left side of the main frame. Its lower outer structure allows more material to fall onto the left side of the detachable screen plate, and its narrowing effect disperses the material, facilitating screening. The support frame provides support on the inner corner of the guide plate, ensuring its structural stability.

[0008] Furthermore, the oscillation generating unit includes a connecting block, a pulling block, a drive motor, a linkage crank, and a connecting shaft. Two connecting blocks are fixedly connected to the lower left side of the main frame. The two connecting blocks are rotatably connected to one end of the pulling block via a rotating shaft.

A connecting shaft is fixedly connected to the side of the linkage crank closest to the pulling block, and the other end of the connecting shaft is rotatably connected to the interior of the left end of the pulling block. A drive motor is installed at the front linkage crank, and the output shaft of the drive motor is fixedly connected to the interior of the front linkage crank away from the connecting shaft. The drive motor drives the linkage crank to rotate, and the linkage crank drives the left end of the pulling block to perform circular motion via the connecting shaft. The connecting block is used for the movable connection between the pulling block and the main frame. Under the drive of the linkage crank, the pulling block can continuously pull and push the main frame, thereby creating a continuous lateral swaying effect on the main frame.

[0009] Furthermore, the oscillation generating unit also includes a connecting slide plate, an external clamping frame, and a support frame. Long, strip-shaped connecting slide plates are fixedly connected to the lower positions of both the front and rear sides of the main frame. These connecting slide plates are horizontally arranged. A set of support frames is provided below the front and rear sides of the main frame. Each support frame consists of a vertical support plate and a bottom plate. Bolt through holes are equidistantly spaced on the outer side of the bottom plate. An external clamping frame is fixedly connected to the upper end of the vertical support plate of the support frame. The external clamping frame has a U-shaped structure with its opening facing inwards. The connecting slide plate is engaged with the connecting slide plate on the outer side of the main frame, limiting the lateral sliding of the main frame and ensuring stable horizontal sliding without vertical displacement.

[0010] Furthermore, the oscillation generating unit also includes a mounting bracket and a motor retaining ring. Two mounting brackets, one front and one rear, are located on the left side of the main frame. Bolt through holes are provided on the lower side plate of each mounting bracket. A motor support plate is fixedly connected to the upper part of the linkage crank on the front side. The drive motor is mounted on the upper side of the motor support plate, and a motor retaining ring is installed on its outer side. Both ends of the motor retaining ring are fixed to the motor support plate by bolts. The upper end of the mounting bracket on the rear side is rotatably connected to the linkage crank via a short shaft. The mounting bracket is used to install and support the drive motor and to support the short shaft at the end of the linkage crank. The motor retaining ring is used to reinforce the drive motor.

[0011] Furthermore, it also includes a support frame and a connecting hose. The feed end of the elevator on its lower side extends into the interior of the transfer bucket, and a connecting hose is fitted onto the discharge end of the elevator on its upper side. The connecting hose connects to the feed inlet of the air jet mill. A vertical support frame is fixedly connected to the lower side of the elevator, and the plate at the lower end of the support frame also has bolt through holes. The support frame is used to support the elevator, and the bottom plate can be fixed in position by adding bolts. The connecting hose at the upper end of the elevator can be bent to connect to the feed inlet of the air jet mill.

Rod-shaped debris and larger material particles in the material will be separated on the upper side of the detachable screen plate. The tilt angle of the main frame, combined with its own oscillation effect, can keep the material in the receiving box and the upper side of the detachable screen plate conveyed to the right while shaking. The guide block makes the qualified material in the receiving box obliquely conveyed forward and fall into the transfer bucket, and then conveyed to the feed port of the air jet pulverizer by the elevator. 2. The guide frame installed on the upper side of the detachable screen plate allows unqualified materials and debris to be discharged obliquely backward. By staggering the discharge direction with that of qualified materials, mixing during discharge is avoided. By screening out larger materials and debris, blockages can be avoided when feeding into the air jet mill. The detachable screen plate is installed and fixed with bolts and is easy to disassemble and replace, thus making it suitable for screening different specifications of material particles. 3. The support frame is used to support the external clamping frame. By adding bolts at the bottom, the support frame can be fixed. The connecting slide plate is engaged with the connecting slide plate on the outside of the main frame to limit the lateral sliding of the main frame, ensuring that the main frame can slide stably in the lateral direction without vertical displacement.

Particles that meet the specifications fall into the receiving box 51 on the lower side through the round holes on the detachable screen plate 54.

The connecting slide plate 48 is engaged with the connecting slide plate 48 on the outside of the main frame 1, which can limit the lateral sliding of the main frame 1 and ensure that the main frame 1 slides horizontally in a stable manner without vertical displacement. The guide frame 55 installed on the upper side of the detachable screen plate 54 allows unqualified materials and debris to be discharged obliquely backward. By offsetting the discharge direction from that of qualified materials, mixing during discharge is avoided.
