Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to a combined high-efficiency drying device. Background Art

[0002] Legumes are a kind of plant fruit that contains nutrients such as protein, carbohydrates, vitamins, etc. They are widely used as food raw materials. In the process of legume processing, cleaning is an important step in the processing of legumes. Cleaning can effectively remove dust, sand and other impurities on the surface of legumes, ensure the sanitary quality of legumes, and reduce or remove harmful substances such as fertilizers and pesticides that may remain on legumes.

[0003] After washing, a large amount of water stains remain on the outer wall of bean crops, which increases the humidity on the surface of bean crops. The residual water stains can become a hotbed for mold growth, making bean crops prone to mold and deterioration. Therefore, it is necessary to dry quickly and maintain a suitable dry state to avoid mold growth and extend the shelf life. In the subsequent drying process, direct drying is performed because the residual water stains on the outer wall of bean crops will lead to high energy consumption. Therefore, those skilled in the art provide a combined high-efficiency drying device to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to provide a combined high-efficiency drying device in view of the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a combined high-efficiency drying device, comprising a box body, a travel plate, a belt conveyor, a mounting frame, a mounting frame and a grid frame, wherein a symmetrically distributed mounting frame is arranged inside the box body, a mounting frame is arranged inside the mounting frame, a rotating shaft is arranged at both the front and rear ends of the mounting frame, a motor 1 whose output end is connected to the rotating shaft is arranged at one end of the mounting frame, a grid cylinder is arranged inside the mounting frame, a filter cartridge is arranged inside the grid cylinder, a mounting shaft rotatably mounted on the upper end of the mounting frame is arranged at the lower end of the grid frame, a motor 2 is arranged on one side of the mounting shaft, a gear is arranged at the output end of the motor 2, a gear is sleeved on the outer wall of the mounting shaft with a gear ring meshing with the gear, an L-shaped travel groove is opened inside the rear end of the box body, a travel plate is slidably installed inside the travel groove, a belt conveyor is arranged inside the lower end of the box body, a guide cover is arranged below the belt conveyor, and a connecting pipe penetrating the box body is arranged at one end of the guide cover.

[0006] Preferably, a feed hopper with an output port located above the grid tube is provided inside the upper end of the box body. The bean crops are transported by being transported to the feed hopper, and the bean crops are transported to the inside of the grid tube through the feed hopper.

[0007] Preferably, one side of the upper end of the travel plate is in the shape of an inclined surface, and a guide plate is provided inside one side of the box body. The water drops falling to the upper end of the travel plate are transported through the inclined surface, and the guide plate limits the water drops during their falling process, thereby guiding the intercepted water drops.

[0008] Preferably, a water collecting trough is provided inside one side of the lower end of the box body, one side of the lower end of the guide plate is located inside the water collecting trough, and a drainage pipe penetrating the water collecting trough and controlled to open and close by a valve is provided inside one end of the box body. Water droplets limited by the guide plate are collected by the water collecting trough, and the water collected inside the water collecting trough is transported to the outside through the drainage pipe. During the use of the drainage pipe, the opening and closing of the interior is controlled by the valve to discharge the collected water inside the water collecting trough.

[0009] Preferably, a hydraulic rod is provided at the upper end of the box, and a connecting block connected to the upper end of the travel plate is provided at the telescopic end of the hydraulic rod. When the hydraulic rod is in operation, the driving force of the telescopic end drives the travel plate to move through the connecting block, so that the travel plate slides inside the box.

[0010] Preferably, a moisture outlet is provided on one side of the upper end of the box, and the box is provided with baffles located at both sides of the front and rear of the conveyor belt. When the evaporated moisture in the box flows upward, it is discharged through the moisture outlet. During the conveyor belt conveying the bean crops, the baffles are used to limit the position of the bean crops to prevent the bean crops from moving through the front and rear sides of the conveyor belt and detaching from the conveyor belt. The baffles are used to limit the position of the bean crops to ensure the effective conveyance of the bean crops by the conveyor belt.

[0011] Preferably, the connecting pipe is provided with a flange at the opening of one end outside the box, and a filter is provided inside the deflector. The connecting pipe is connected to the heat source, and the pipes are butt-connected and installed through the flange. The filter intercepts solid matter or impurities in the heat source to prevent such pollutants from entering the box and the interior, thereby contaminating the bean crops during the drying process.

[0012] Preferably, a discharge port is provided inside one end of the box, and the belt conveyor passes through the discharge port. The bean crops transported by the conveyor belt are discharged through the discharge port, and the discharge port enables the belt conveyor to operate effectively inside the box.

[0013] Preferably, a conveyor belt is rotatably installed inside the belt conveyor, and the conveyor belt is provided with through holes distributed at equal intervals. Through the through holes inside the conveyor belt, the heat source can flow through the conveyor belt and effectively act on the bean crops.

[0014] Preferably, the conveyor belt is inclined, the lower part of the conveyor belt is located below the grid tube, and the outer wall of the conveyor belt is provided with lifting plates distributed at equal intervals. The conveyor belt is inclined, and the conveyed bean crops are lifted and conveyed, and the bean crops dumped through the grid tube are received by the conveyor belt, and the lifting plates intercept the bean crops flowing downward. The lifting plates move with the conveyor belt, and the conveyor belt effectively conveys the bean crops.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] After washing, the bean crops of the present invention are transported to the inside of the grid drum and carried by the filter drum. The grid drum rotates by itself to drive the carried bean crops to rotate. Due to the effect of centrifugal force, water stains entangled on the outer wall of the bean crops are easily scattered outward along the gravity or quickly separated, so that the outer wall of the bean crops is more easily dried. Before drying, the bean crop food is quickly separated from the water stains, which greatly reduces the residual water stains on the outer wall of the bean crops after washing. Subsequently, the bean crops are dried by the drying equipment. Due to the reduction of water stains, the bean crops are dried quickly. Since the drying time is shortened, the energy consumption is reduced. Through the combined drying equipment, the bean crops are dried with high efficiency and energy saving.

The harmful substances such as fertilizers and pesticides that may remain on the beans are removed, and the taste is better, avoiding the quality of the beans being affected by pollution. The washed bean crops are poured into the feed hopper 6, and are input into the grid cylinder 14 through the feed hopper 6. The liquid material on the outer wall of the bean crops drips downward through the opening of the grid cylinder 14. The filter cylinder 28 is in direct contact with the bean crops to prevent the bean crops from falling to the outside through the grid cylinder 14.
