Description

Technical Field

[0001] This utility model relates to the technical field of material feeding, and in particular to a dust-free feeding device for high-concentration color masterbatch powder raw materials. Background Technology

[0002] A powder feeding device is a device used for feeding materials, commonly used in material storage or processing. In masterbatch production plants, powdered raw materials, such as inorganic or organic pigments, need to be stored in silos. During production, the raw materials are retrieved from the silos. When adding powdered raw materials to the silos, a feeding device is needed. For example, utility model patent application number 202123032935.2 discloses a dust-free feeding device for environmentally friendly white masterbatch, which mainly consists of a silo with a feeding port at the top. When feeding materials into the silo, the materials are added through the feeding port at the top. However, this device has the following problems: when powdered materials are added to the silo through the feeding port, the powdered materials collide with the side wall near the feeding port, easily generating dust near the feeding port, affecting the working environment and making it inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a dust-free feeding device for high-concentration color masterbatch powder raw materials that reduces dust drifting into the environment during the feeding process, is easy to use, environmentally friendly, and highly practical.

[0004] This utility model relates to a dust-free feeding device for high-concentration masterbatch powder raw materials, comprising a base plate, a hopper, and a feeding port. The hopper is mounted on the base plate and contains a chamber. The feeding port, communicating with the chamber, is located at the top of the hopper. The device also includes a conveying pipe, a suction pipe A, a suction pipe B, a conveying mechanism, and a vacuum suction mechanism. The conveying mechanism is mounted on the hopper and facilitates material transport. The input end of suction pipe B is near the feeding port, and the input end of suction pipe A is located at the top of the hopper chamber. The output ends of both suction pipes A and B are connected to the conveying pipe, which is connected to the vacuum suction mechanism. The vacuum dust collection mechanism has a dust collection function. In the color masterbatch production plant, when it is necessary to add powdered raw materials into the hopper, the powdered raw materials are first added into the feeding port. Then, the conveying mechanism is opened to promote the downward movement of the powdered raw materials in the feeding port, preventing the raw materials from clogging in the feeding port. At the same time, the vacuum dust collection mechanism is opened, so that the dust floating near the feeding port enters the conveying pipe through the dust collection pipe B, and the dust floating in the hopper chamber enters the conveying pipe. Then, the dust enters the vacuum dust collection mechanism for treatment. This reduces the dust that is scattered into the environment during the feeding process. It is convenient to use and has high environmental protection and practicality.

[0005] Preferably, the conveying mechanism includes a support frame, a motor A, a rotating shaft, and a spiral blade A. The support frame is fixedly installed on the hopper, the motor A is fixedly installed on the upper end of the support frame, the rotating shaft is rotatably installed on the support frame, and the upper end of the rotating shaft is connected to the power output end of the motor A. The spiral blade A is fixedly installed on the rotating shaft and is located in the feeding port. When powdery raw materials are added to the hopper through the feeding port, the motor A is turned on. The motor A rotates the spiral blade A through the rotating shaft. The rotating spiral blade A promotes the movement of the raw materials in the feeding port into the hopper, preventing the raw materials from causing blockage in the feeding port. This method has high reliability and practicality.

[0006] Preferably, the vacuum cleaning mechanism includes a dust collection box, a partition, an exhaust fan, a circular tube, and a mesh cylinder. The dust collection box is mounted on a base plate, and the partition is fixedly installed inside the dust collection box, dividing the dust collection box into two independent left and right chambers. The exhaust fan is mounted on the dust collection box, and its input end is connected to the left chamber of the dust collection box. A valve is installed on the exhaust fan. The circular tube is rotatably mounted on the partition, with its left and right ends located in the left and right chambers, respectively. The mesh cylinder is fixedly installed on the right end of the circular tube, and a filter screen is installed on the mesh cylinder, covering the outer wall of the dust collection pipe A. The output end of the conveying pipe is connected to the upper part of the right chamber of the dust collection box, and a valve is installed on the conveying pipe. When the exhaust fan is turned on, the left chamber of the dust collection box is created under negative pressure, allowing dust and air from the conveying pipe to enter the right chamber of the dust collection box. The air is then filtered by the filter screen on the mesh cylinder and enters the left chamber of the dust collection box through the mesh cylinder and the circular tube. The clean air is then discharged by the exhaust fan, while the dust remains on the filter screen.

[0007] Preferably, it also includes a high-pressure gas storage tank and an exhaust pipe. The output end of the high-pressure gas storage tank is equipped with an exhaust pipe, and the lower part of the exhaust pipe is equipped with multiple air blowing pipes, all of which are located in the mesh cylinder. A pulse valve is installed on the exhaust pipe. The input end of the high-pressure gas storage tank is connected to an external gas supply system. When it is necessary to clean the dust on the filter screen on the outer wall of the mesh cylinder, the valves on the delivery pipe and the induced draft fan are closed, and the pulse valve on the exhaust pipe is opened, so that the compressed air in the high-pressure gas storage tank is blown into the mesh cylinder through the air blowing pipe and multiple air blowing pipes. The dust on the filter screen of the mesh cylinder is blown off by the compressed air, which facilitates the cleaning of the mesh cylinder.

[0008] Preferably, it also includes a motor B and a rotating shaft. The motor B is fixedly mounted on the dust collection box, and the power output end of the motor B is provided with a rotating shaft. The rotating shaft is fixedly mounted on the right end of the screen cylinder and is coaxial with the round tube. When the exhaust pipe and the air blowing pipe blow dust off the screen cylinder, the motor B is turned on. The motor B drives the rotating shaft to rotate, and the rotating shaft drives the screen cylinder to rotate, so that the dust in the circumferential direction of the screen cylinder can be blown off by multiple air blowing pipes, which facilitates the cleaning of dust on the screen cylinder.

[0009] Preferably, the device further includes a servo motor, a rotating shaft, and a spiral blade B. A cleaning port communicating with the right cavity is provided on the lower right side of the dust collection box, and a sealing cover is provided outside the cleaning port. The servo motor is mounted on the dust collection box, and a rotating shaft is provided at the power output end of the servo motor. The rotating shaft is rotatably mounted on the dust collection box and the partition. The spiral blade B is fixedly mounted on the rotating shaft and is located inside the right cavity of the dust collection box, to the left of the cleaning port. When it is necessary to clean the dust in the lower right cavity of the dust collection box, the sealing cover on the dust collection box is opened, and then the servo motor is turned on, causing the rotating shaft to drive the spiral blade B to rotate. This allows the dust in the lower right cavity of the dust collection box to be pushed out through the cleaning port by the rotating spiral blade B, facilitating the cleaning of the dust in the lower right cavity of the dust collection box.

[0010] Preferably, the dust collection box is provided with a transparent observation window; this feature facilitates the monitoring of the working status of the equipment in the dust collection box and improves convenience.

[0011] Compared with the prior art, the advantages of this utility model are: it reduces the dust that drifts into the environment during the feeding process, is convenient to use, and is highly environmentally friendly and practical. Attached Figure Description

The output ends of both the dust collection pipe A5 and the dust collection pipe B6 are connected to the conveying pipe 4. The conveying pipe 4 is connected to the vacuum dust collection mechanism. The mechanism is connected, and the vacuum dust collection mechanism has a dust collection function. In the color masterbatch production plant, when it is necessary to add powdered raw materials into the hopper 2, the powdered raw materials are first added into the feeding port 3. Then, the conveying mechanism is opened to promote the downward movement of the powdered raw materials in the feeding port 3, preventing the raw materials from clogging in the feeding port 3. At the same time, the vacuum dust collection mechanism is opened, so that the dust floating near the feeding port 3 enters the conveying pipe 4 through the dust collection pipe B6, and the dust floating in the chamber of hopper 2 enters the conveying pipe 4. Then, the dust enters the vacuum dust collection mechanism for treatment. This reduces the dust that is scattered into the environment during the feeding process, is convenient to use, and has high environmental protection and practicality.

The rotating spiral blade A10 promotes the movement of the raw materials in the feeding port 3 into the hopper 2, preventing the raw materials from causing blockage in the feeding port 3. It has high reliability and practicality.

When the induced draft fan 13 is turned on, the left cavity of the suction box 11 is made into a negative pressure, so that the dust and air in the conveying pipe 4 enter the right cavity of the suction box 11. Then, the air is filtered by the filter screen on the mesh cylinder 15 and enters the left cavity of the suction box 11 through the mesh cylinder 15 and the circular tube 14.
