Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a deceleration device for a solid powder material ultra-dense phase conveying system. Background Technology

[0002] In factory production, vertical conveyor pipes are often used to guide powdery materials from chutes into bucket elevators for further processing. However, the drop in these vertical conveyor pipes often exceeds 3 meters, and the impact of falling high-density, densely packed materials on the bucket elevator is significant, easily causing the elevator motor to overload and damaging the equipment. Therefore, some existing technologies incorporate inclined buffer plates inside the vertical conveyor pipes for deceleration. However, these inclined buffer plates are mostly fixed designs, and densely packed materials typically have high concentration, high viscosity, and high solids content, resulting in poor flowability. They are difficult to completely slide off the inclined plates during descent, easily leaving residue on the plate surface. Furthermore, high-density materials have strong adhesion, and the residue gradually accumulates and combines with impurities and moisture in the air to form a hardened layer of dirt, requiring regular cleaning. Fixed buffer plates are not only inconvenient to clean but also ineffective at achieving thorough cleaning. Therefore, this invention proposes a material deceleration device for a densely packed solid powder material conveying system. Utility Model Content

[0003] The purpose of this invention is to provide a deceleration device for a solid powder material ultra-dense phase transport system, thereby solving the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a material deceleration device for a solid powder material ultra-dense phase transport system, comprising a vertical conveying pipe, on which inclined slots are equally spaced and staggered along the vertical direction. A buffer inclined plate is slidably disposed in the inclined slots. A driving mechanism is provided on the vertical conveying pipe to drive the buffer inclined plate to move along the direction of the inclined slots. The horizontal distance between the bottom of the buffer inclined plate and the vertical conveying pipe is greater than the inner radius of the vertical conveying pipe.

[0006] Furthermore, the driving mechanism includes bottom fixing blocks symmetrically arranged on the outer wall of the vertical conveying pipe, the bottom fixing blocks being located at the bottom of the inclined slot; a top fixing block is provided on the outer wall of the vertical conveying pipe below the top of the inclined slot, a lead screw is rotatably arranged between the top fixing block and the bottom fixing block, the lead screw passing through the bottom fixing block and connected to a motor; and sliders cooperating with the lead screw are symmetrically arranged at the bottom of the buffer inclined plate.

[0007] Furthermore, the bottom of the buffer ramp is provided with several sliding strips, and the upper surface of the top fixing block is provided with a sliding groove that cooperates with the sliding strips.

[0008] Furthermore, the motor is a reversible motor.

[0009] Furthermore, the bevel angle of the inclined slot is 30°-60°.

[0010] Furthermore, the buffer ramp has a rectangular structure.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This utility model relates to a solid powder material ultra-dense phase conveying system with a material deceleration device. During the material's descent, it sequentially contacts and collides with various buffer inclined plates, forming an "S"-shaped material deceleration path, thus slowing down its flow velocity and reducing the impact force during the material's fall. Furthermore, a drive mechanism drives the buffer inclined plates to move out of the vertical conveying pipe, periodically cleaning the dirt layer on their surfaces. This allows the material to slide smoothly along the smooth plate surface, ensuring the normal operation of the equipment and extending its service life. Attached Figure Description

[0018] like Figure 1-3As shown, a solid powder material ultra-dense phase transport system material deceleration device includes a vertical conveying pipe 1. The vertical conveying pipe 1 has equidistant, staggered inclined slots 11 along the vertical direction, with an angle of 30°-60°. A buffer inclined plate 2 is slidably installed within the inclined slot 11. A driving mechanism is installed on the vertical conveying pipe 1 to drive the buffer inclined plate 2 to move along the inclined slot 11. The horizontal distance between the bottom of the buffer inclined plate 2 and the vertical conveying pipe 1 is greater than the inner radius of the vertical conveying pipe 1, forming an "S"-shaped material deceleration and falling path within the vertical conveying pipe 1, dispersing the impact force of the falling material and protecting downstream equipment.

[0019] The driving mechanism includes bottom fixing blocks 5 symmetrically installed on the outer wall of the vertical conveying pipe 1, located at the bottom of the inclined slot 11; a top fixing block 3 is installed on the outer wall of the vertical conveying pipe 1 below the top of the inclined slot 11; a lead screw 4 is rotatably installed between the top fixing block 3 and the bottom fixing block 5; the lead screw 4 passes through the bottom fixing block 5 and is connected to a motor 6; the motor 6 is electrically connected to a control device, which can control the synchronous start and stop of the two motors 6, and simultaneously control the stroke, rotation, forward and reverse rotation, etc. of the motors 6 (this is existing technology and will not be elaborated further); the bottom of the buffer inclined plate 2 is symmetrically equipped with sliders 21 that cooperate with the lead screw 4. Specifically, when the motor 6 is started, it drives the lead screw 4 to rotate. According to the lead screw principle, under the constraint of the inclined slot 11, the sliders 21 drive the buffer inclined plate 2 to move up / down in the inclined direction. During the relative sliding process between the buffer inclined plate 2 and the vertical conveying pipe 1, the inner wall of the vertical conveying pipe 1 scrapes and cleans the surface of the buffer inclined plate 2.

[0020] The bottom of the buffer ramp 2 is equipped with several sliding strips, and the upper surface of the top fixing block 3 is provided with a sliding groove that cooperates with the sliding strips to ensure the stability of the sliding process and avoid misalignment.

[0021] The motor 6 is a forward and reverse reversible motor.

[0022] The buffer ramp 2 has a rectangular structure.

[0023] The operation process of this utility model is as follows:

[0024] The material in the chute flows into the vertical conveying pipe 1 and falls to the bucket elevator below under gravity. During the falling process, the super-dense phase material comes into contact with and collides with each buffer inclined plate 2 in turn, which slows down its own flow velocity and makes it have a smaller impact force when it reaches the bucket elevator.

[0025] Regular maintenance and cleaning process: Start motor 6 to drive lead screw 4 to rotate, drive slider 21 to move buffer inclined plate 2 upward in the inclined direction. During the process of buffer inclined plate 2 sliding relative to vertical conveying pipe 1, the inner wall of vertical conveying pipe 1 scrapes and cleans the surface of buffer inclined plate 2. After moving upward and completely separating from vertical conveying pipe 1, the surface is cleaned. Finally, after cleaning is completed, motor 6 drives lead screw 4 to rotate in the reverse direction, slider 21 drives buffer inclined plate 2 to move downward in the inclined direction, and reset.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
