Description

Technical Field

[0001] This utility model relates to the field of feeding system technology, specifically to a pneumatic feeding system. Background Technology

[0002] In the production of refractory bricks, feeding equipment is needed to transport powdered raw materials. Traditional refractory material conveying mainly relies on mechanical conveying equipment (such as belt conveyors and screw conveyors). When using traditional mechanical conveying equipment to transport refractory materials, dust easily spills out during transportation, resulting in serious dust pollution of the surrounding environment and affecting the health of operators. To address this, we propose a pneumatic feeding system. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic feeding system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic feeding system, including an open-bag hopper, a buffer chamber fixedly connected to the outlet of the open-bag hopper via a connecting pipe, auxiliary feeding components fixedly mounted symmetrically on the side walls of the buffer chamber, a format feeder fixedly connected to the outlet end of the buffer chamber, a feeding mechanism fixedly connected to the output end of the format feeder, and a manual gate valve installed between the open-bag hopper and the buffer chamber.

[0005] Preferably, the feeding mechanism includes a Roots blower, with one end of a connecting pipe fixedly connected to the output end of the Roots blower, and the other end of the connecting pipe fixedly connected to a feeding pipe. A butterfly valve is fixedly connected to the end of the feeding pipe, and the feeding pipe is fixedly connected to the outlet of the feeder.

[0006] Preferably, a vibration damper is fixedly installed between the Roots blower and the connecting pipe.

[0007] Preferably, an exhaust pipe is fixedly installed between the side wall of the bag-opening hopper and the buffer hopper.

[0009] Preferably, the mounting bracket is L-shaped, and a limiting groove is provided on the top of the mounting bracket. A limiting slider is fixedly connected to the top of the collision bracket, and the limiting slider is slidably connected in the limiting groove.

[0010] Preferably, the collision frame includes a collision frame body, the collision frame body is arc-shaped, and the side walls of the collision frame body are integrally formed with collision columns in a symmetrical manner from front to back.

[0011] Compared with the prior art, the beneficial effects of this utility model are: a pneumatic feeding system adopts an enclosed pneumatic feeding method. After the material is unpacked, it can be transported by the feeding mechanism. During the feeding process, the spillover of dust into the surrounding environment can be reduced, dust pollution can be reduced, and the surrounding operators can be protected.

[0012] Furthermore, the buffer chamber has been redesigned in this utility model. An exhaust pipe is installed between the bag opening hopper and the buffer chamber, and an auxiliary feeding component is installed on the side wall of the buffer chamber. Through the cooperation of the exhaust pipe and the auxiliary feeding component, the material in the buffer chamber can be effectively dropped, avoiding the accumulation of material on the inner wall of the buffer chamber and forming a feeding mechanism.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a pneumatic feeding system, including a bag-opening hopper 1. The bag-opening hopper 1 has an internal structure that can open bags for materials (this is a mature application of existing technology, so the internal bag-opening structure will not be described in detail). At the same time, a dust collector 2 is provided on the side wall of the bag-opening hopper 1. During the bag-opening operation, the dust collector 2 can reduce the spillage of dust into the surrounding environment and protect the surrounding environment. A buffer chamber 3 is fixedly connected to the bottom outlet of the bag-opening hopper 1 via a connecting pipe. After the bag-opening hopper 1 completes the bag-opening operation, the material enters the buffer chamber 3 for temporary storage. A manual gate valve 4 is fixedly installed in the connecting pipe between the bag-opening hopper 1 and the buffer chamber 3. The opening and closing of the bag-opening hopper 1 and the buffer chamber 3 can be controlled by the manual gate valve 4. A feeder 5 is fixedly connected to the bottom of the buffer chamber 3. The buffer chamber 3 is connected to the feeding mechanism 6 through the feeder 5. The material in the buffer chamber 3 falls evenly into the feeding mechanism 6 through the feeder 5, and is then fed to the next processing step through the feeding mechanism 6.

[0020] like Figure 1 As shown, the feeding mechanism 6 includes a Roots blower 61. One end of a connecting pipe 62 is fixedly connected to the output end of the Roots blower 61, and the other end of the connecting pipe 62 is fixedly connected to one end of a feeding pipe 63. The other end of the feeding pipe 63 is connected to an external feeding pipeline, and a butterfly valve 64 is installed between the feeding pipe 63 and the external feeding pipeline. The butterfly valve 64 controls the connection between the feeding pipe 63 and the external feeding pipeline. The outlet of the feeder 5 is connected to the feeding pipe 63, and material enters through the feeder 5. After intermittently entering the feeding pipe 63, the air driven by the Roots blower 61 in the connecting pipe 62 and the feeding pipe 63 generates power to feed the material. A vibration damper 65 is fixedly installed between the Roots blower 61 and the connecting pipe 62. By setting the vibration damper 65, the vibration between the connecting pipe 62 and the Roots blower 61 can be reduced, and the connection and fixed position of the connecting pipe 62 can be protected. The diameter of the connecting pipe 62 is larger than the diameter of the feeding pipe 63, which plays a role in energy storage during the transportation of materials.

[0021] like Figure 1 As shown, an exhaust pipe 7 is fixedly installed between the side wall of the bag-opening hopper 1 and the top of the buffer hopper 3. By setting the exhaust pipe 7, air is allowed to enter the buffer hopper 3 during the bag-opening operation of the material in the bag-opening hopper 1, so that the material in the buffer hopper 3 can fall down and the material is prevented from accumulating on the inner side wall of the buffer hopper 3.

[0022] At the same time, such as Figure 1 , Figure 2 and Figure 3As shown, the side wall of the buffer chamber 3 is fixedly equipped with auxiliary feeding components 8 that are symmetrically distributed on the left and right. During the feeding process of the buffer chamber 3, the feeding phenomenon is prone to occur, that is, a small part of the material falls from the middle of the buffer chamber 3 into the feeder 5 below, while most of the material accumulates on the side wall of the buffer chamber 3. By setting the auxiliary feeding components 8, the buffer chamber 3 can be effectively tapped from the left and right directions, thereby avoiding the accumulation of material on the inner wall of the buffer chamber 3 and maintaining its stable feeding effect.

[0023] The auxiliary feeding component 8 includes a mounting frame 81, which is L-shaped. The mounting frame 81 is detachably and fixedly mounted to the side wall of the buffer chamber 3 by fixing bolts. The mounting frame 81 is fixedly mounted with telescopic cylinders 82 that are symmetrically distributed at the top and bottom. The output end of the telescopic cylinder 82 is fixedly connected to a collision frame 83. The input end of the telescopic cylinder 82 is connected to an external air pump. The external air pump can make the output end of the telescopic cylinder 82 reciprocate and extend. The telescopic cylinder 82 drives the reciprocating motion of the collision frame 83, so that the collision frame 83 repeatedly collides with the side wall of the buffer chamber 3, which can prevent the material from accumulating on the inner wall of the buffer chamber 3 and causing feeding problems.

[0024] The top of the collision frame 83 is fixedly connected to a limiting slider 84, which is slidably connected in a limiting groove 85. The limiting groove 85 is opened on the top of the mounting frame 81. Through the sliding connection between the limiting slider 84 and the limiting groove 85, the movement stroke of the collision frame 83 can be limited to maintain the accuracy of the movement stroke of the collision frame 83.

[0025] like Figure 4 As shown, the collision frame 83 includes a collision frame body 831, which is arc-shaped and its size is adapted to the size of the buffer chamber 3. The inner sidewall of the collision frame body 831 is integrally formed with collision columns 832 in a symmetrical manner from front to back. Both the collision frame body 831 and the collision columns 832 are injection molded from hard rubber material, so that when they come into contact with the buffer chamber 3, they can exert a certain impact force on the buffer chamber 3, while avoiding deformation and damage to the buffer chamber 3 due to excessive impact force.

[0026] Working principle: When using this system to transport materials, first control the Roots blower 61 to start, and then control the butterfly valve 64 to open. At this time, the Roots blower 61 delivers external air to the feeding pipe 63 through the connecting pipe 62. The bagged material enters the bag opening hopper 1, and the bag opening hopper 1 performs the bag opening operation. During the bag opening process, the dust collector 2 can effectively reduce the spillage of dust into the surrounding environment. At the same time, the material enters the buffer hopper 3 below. The feeder 5 evenly feeds the material into the feeding mechanism 6. When the material enters the feeding pipe 63, it is pushed into the next device by the wind. When the buffer hopper 3 buffers the material, the reciprocating action of the auxiliary feeding component 8 can knock down the material accumulated in the side wall of the buffer hopper 3, avoiding the material from touching the inner wall of the buffer hopper 3 and causing feeding phenomenon.
