Description

Technical Field

[0001] The utility model relates to the technical field of dry powder feeding, in particular to a dry powder feeding machine with a dust collection unit. Background Art

[0002] Dry powder feeder, also known as dry powder elevator, can automatically feed raw materials during the production process to improve production efficiency and product quality. However, due to its own characteristics, dry powder often produces dust at its discharge port, affecting the working environment.

[0003] The existing dust treatment method is often to place a high-power dust collection device at the point where dust is generated. When dust is generated, the dust collection device can be used to generate a negative pressure airflow, and the dust is sucked into the interior of the dust collection device along with the negative pressure airflow;

[0004] This type of method of installing a vacuum cleaner to handle dust will have some problems in operation. Dry powder has characteristics. Dry powder subjected to negative pressure airflow will produce more dust. For this reason, we propose a dry powder loader with a dust collection unit. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a dry powder loader with a dust collection unit, which will not generate more dust due to the intersection of the dry powder's own characteristics with the dust collection unit, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dry powder feeder with a dust collection unit, comprising a bracket, a feeding mechanism and a dust collection mechanism;

[0007] Bracket: A feed hopper is arranged inside the bracket, and a silo is arranged at the upper end of the feed hopper;

[0008] Feeding mechanism: It includes a feeding cylinder and a discharging pipe. The feeding cylinder is arranged at the lower end of the feeding hopper, and the discharging pipe is arranged at the right end of the outer arc surface of the feeding cylinder;

[0009] Dust suction mechanism: it includes a dust box, a dust outlet pipe and an oblique arrangement plate. The dust box is fixedly connected to the left inner wall of the silo. An evenly distributed oblique arrangement plate is provided on the right side between the front and rear inner walls of the dust box. A dust outlet pipe is provided at the upper end of the dust box. The outer arc surface of the dust outlet pipe is fixedly connected to the upper side wall of the silo. The dust outlet pipe is connected to an external dust suction device. The structure of the dust suction unit is simple and clear, and more dust will not be generated due to the intersection of the characteristics of the dry powder itself with the dust suction unit, thereby avoiding affecting the feeding operation.

[0010] Furthermore, it also includes a control switch, which is arranged on the front side of the bracket, and the input end of the control switch is electrically connected to an external power supply to control the normal operation of the driving machine.

[0011] Furthermore, the feeding mechanism also includes a bearing seat, a rotating rod and a spiral piece. The bearing seat is arranged on the left side of the discharge pipe. The inside of the bearing seat is rotatably connected to the rotating rod. The right end of the rotating rod is rotatably connected to the right side wall of the discharge pipe. The outer arc surface of the rotating rod is provided with a spiral piece to realize the function of conveying dry powder.

[0012] Furthermore, the feeding mechanism also includes a driven tilt gear, a driving tilt gear and a driving machine. The driven tilt gear is fixedly connected to the right end of the rotating rod. The driving machine is provided at the bottom of the bracket. The output shaft of the driving machine is fixedly connected to the driving tilt gear. The driven tilt gear is meshingly connected with the driving tilt gear. The input end of the driving machine is electrically connected to the output end of the control switch to realize the driving function.

[0013] Furthermore, it also includes a barrel rack, which is arranged in the middle of the left end of the bracket. The interior of the barrel rack is fixedly connected to the middle of the outer arc surface of the feed barrel to achieve the function of middle support of the barrel.

[0014] Furthermore, it also includes universal wheels, which are respectively arranged at the four corners of the bottom surface of the bracket to achieve the function of simply moving the loader.

[0015] Furthermore, the dust suction mechanism also includes a sealing door and a handle. The sealing door is connected to the upper end of the silo through a pin shaft, and a handle is provided on the right side of the upper surface of the sealing door.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the dry powder feeder with a dust collection unit has the following advantages:

[0017] During the lifting operation and the dry powder feeding process, it is necessary to pour the dry powder into the silo manually. In the process of pouring the dry powder, the dry powder will generate a large amount of dust due to its own properties. The dust will fill the entire silo. If not handled in time, the dust will overflow. At this time, the external dust collection equipment can be adjusted to generate negative pressure airflow. The negative pressure airflow continues to inhale the dust along the dust outlet pipe and the oblique arrangement plate. At the same time, the manual operation can also close the sealing door by the handle to temporarily seal the silo. After the dust is sucked out, the external dust collection equipment can be adjusted to reduce the suction force. At this time, the sealing door can be opened. At this time, the oblique arrangement plate will continue to absorb the small amount of dust generated by subsequent transportation with a smaller suction force to complete the dust collection operation. The structure of the dust collection unit is simple and clear, and more dust will not be generated due to the intersection of the dry powder's own characteristics with the dust collection unit, thereby avoiding affecting the feeding operation.
