Description

Technical Field

[0001] The utility model relates to the technical field of vacuum belt dryers, in particular to a material distribution device and a vacuum belt dryer. Background Art

[0002] The vacuum belt dryer is a continuous contact vacuum drying equipment. The material distribution device on the currently commonly used belt dryer is a connecting rod mechanism driven by a motor. The rotation of the rotating shaft allows the material distribution tube to swing within a specified angle range whose arc does not exceed the width of the conveyor belt, thereby achieving material laying on the conveyor belt.

[0003] However, due to the different concentration, viscosity, and thinness of different materials, the same cloth width range will cause thin materials to easily flow outside the cloth conveyor belt, wasting materials and making the internal cleaning of the belt dryer very troublesome. At the same time, the connecting rod mechanism is prone to jamming when the conveyor pipe returns to one end of the conveyor belt, resulting in uneven cloth at both ends of the conveyor belt, affecting the performance of the final dried product.

[0004] The utility model with publication number CN209917284U discloses a vacuum belt dryer, which includes a feeding system; the feeding system is fed by a screw pump and a feeding branch pipeline with the same number of layers as the transmission belt, and the swing arm extending into the feeding end of each layer of the conveyor belt on the vertical axis is driven by the material laying motor through the crank to swing back and forth, and the material spouting nozzle connected to each feeding branch pipeline on the swing arm evenly arranges the slurry raw material on the conveyor belt. However, the cloth width of the above vacuum belt dryer cannot be adjusted, and it cannot meet the cloth width requirements of materials with different characteristics. Utility Model Content

[0005] The utility model aims to solve the defects in the prior art and provide a material distribution device and a vacuum belt dryer to achieve the adjustment of material width and meet the requirements of material width of different materials.

[0006] To achieve the above-mentioned purpose, the utility model provides a material distribution device and a vacuum belt dryer, comprising a material distribution assembly, a swing frame and a crank rocker assembly, wherein the material distribution assembly is arranged on the swing frame;

[0007] The crank rocker assembly is used to swing the cloth assembly, and includes a driving arm, a bearing, a crank and a driving member for driving the crank to rotate, and the swing frame is connected to the driving arm;

[0008] A slide groove is provided on the driving arm, and a plurality of bearing mounting parts are provided on the crank, and each bearing mounting part is at a different distance from the central axis of the crank; one end of the bearing extends into the slide groove and is slidably connected to the driving arm, and the other end is connected to the crank through the bearing mounting part.

[0009] The driving member is connected to the central axis of the crank and drives the crank to rotate. The crank is connected to the driving arm through a bearing. The driving member drives the crank to rotate, so that the bearing arranged on the crank rotates and drives the driving arm to move, thereby causing the swing frame to swing. The cloth assembly is arranged on the swing frame, and the swinging movement of the swing frame causes the cloth assembly to swing. By setting the above structure, the utility model converts the circular motion of the crank into the swinging motion of the cloth assembly, so that the process of laying the cloth is more uniform.

[0010] The crank is provided with a plurality of bearing mounting parts, and the distances between the centers of different bearing mounting parts and the central axis of the crank are different. Before using the material distribution device, by installing the bearings on different bearing mounting parts, the connection position between the crank and the driving arm can be adjusted, and the rotation angle of the swing frame can be adjusted, thereby adjusting the swing amplitude of the material distribution assembly to meet the requirements of different material distribution widths, with a wider range of adaptability, and can avoid material flow, thereby improving the drying and cleaning efficiency of the belt dryer.

[0011] Optionally, the swing frame is provided with a sealing assembly, and the sealing assembly is used to prevent the material in the cloth assembly from entering the crank rocker assembly.

[0012] Optionally, the sealing assembly includes a sealing disk and a sealing cover. The sealing cover is arranged above the crank rocker assembly to prevent the laid material from entering the crank rocker assembly when the material distributing device swings, thereby damaging the crank rocker assembly. When the sealing disk is arranged outside the sealing cover, the sealing disk can collect the material dripping on the sealing cover, thereby improving the utilization rate of the material.

[0013] Optionally, the cloth assembly is arranged on the swing frame via a clamping member. The clamping member is detachably arranged on the swing frame, and the position of the clamping member on the swing frame is adjusted to adjust the position of the cloth assembly.

[0014] Optionally, the material distribution assembly includes a material distribution tube, which is arranged on the swing frame through a clamping piece, and the material distribution tube is provided with a feed inlet and a material distribution nozzle.

[0015] Optionally, the feed inlet is arranged at one end of the material distribution pipe adjacent to the swing frame, and the material distribution nozzle is arranged at one end of the material distribution pipe away from the swing frame.

[0016] Optionally, the material distribution assembly further includes a heat preservation pipe arranged on one side of the material distribution pipe, and the heat preservation pipe is used to keep the material in the material distribution pipe warm to prevent the material in the material distribution pipe from clogging the material distribution pipe due to low temperature.

[0017] The utility model also provides a vacuum belt dryer, comprising a conveyor belt and the above-mentioned material distribution device, wherein the material distribution device is used for laying materials on the conveyor belt.

[0018] Beneficial effects:

[0019] The utility model is provided with a crank rocker assembly that can make the cloth assembly swing. The crank rocker assembly includes a driving arm, a bearing, a crank and a driving member. The driving member is connected to the central axis of the crank and drives the crank to rotate. The crank is connected to the driving arm through the bearing. The driving member drives the crank to rotate, so that the bearing arranged on the crank rotates and drives the driving arm to move, thereby making the swing frame swing. The cloth assembly is arranged on the swing frame, and the swinging motion of the swing frame makes the cloth assembly swing. The utility model converts the circular motion of the crank into the swinging motion of the cloth assembly by arranging the above structure, so that the process of laying the cloth is more uniform.

[0020] The crank is provided with a plurality of bearing mounting parts, and the distances between the centers of different bearing mounting parts and the central axis of the crank are different. Before using the material distribution device, by installing the bearings on different bearing mounting parts, the connection position between the crank and the driving arm can be adjusted, and the rotation angle of the swing frame can be adjusted, thereby adjusting the swing amplitude of the material distribution assembly to meet the requirements of different material distribution widths, with a wider range of adaptability, and can avoid material flow, thereby improving the drying and cleaning efficiency of the belt dryer.
