Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a double-screw heating and feeding integrated transmission device for dryers. Background Art

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials and is used to dry objects. The dryer vaporizes the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. According to the operating pressure, they can be divided into atmospheric pressure and reduced pressure (reduced pressure dryers are also called vacuum dryers).

[0003] The new box-type structure is the core of the existing spiral dryer. When the dryer is used, the existing technology basically puts the material in first and then dries it. Only after the drying is completed can the material be discharged. It is impossible to achieve continuous feeding and discharging while drying. This drying method greatly reduces the drying efficiency to a certain extent, reduces the production efficiency, and is extremely inconvenient. Therefore, a double-spiral heating and feeding integrated transmission device for the dryer is urgently needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a double-spiral heating and feeding integrated transmission device for a dryer, which solves the problem in the prior art that when the dryer is used, it is inconvenient to heat the material during the feeding process, thereby affecting the subsequent drying work.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A double-helix heating and feeding integrated transmission device for a dryer comprises a box body, a plurality of groups of feeding pipes are rotatably connected inside the box body, and each group of feeding pipes is provided with two feeding pipes, and a plurality of feeding teeth are sleeved on all the feeding pipes, both ends of all the feeding pipes pass through the side wall of the box body, and a driving motor is fixedly connected to the outer wall of the box body near one side of each group of feeding pipes by bolts, one end of one of the feeding pipes in each group is respectively connected to the output shafts of all the driving motors, and two of the feeding pipes in each group are connected by meshing with latches.

[0007] Preferably, two of the feeding pipes in each group are connected to a rotary joint, and one side of all the rotary joints is connected to a connecting pipe.

[0008] Preferably, both ends of all the feeding pipes pass through the side wall of the box body through the bearing sleeve.

[0009] Preferably, two of the feeding tubes in each group are sleeved with gears at one end, and the two gears are connected by meshing with latches.

[0010] Preferably, one side of the outer portion of the box body is rotatably connected to a door body via a hinge.

[0011] Preferably, the top of the box is connected to a feed pipe, and the bottom of the box is equipped with a discharge valve.

[0012] The utility model has at least the following beneficial effects:

[0013] When the utility model is used, a dryer with a double-helix heating and feeding integrated transmission device is firstly put into a box body to be dried, all driving motors are started, and hot air is fed into the feeding pipe through a connecting pipe to heat the feeding pipe so as to heat and dry the material. Moreover, by utilizing the rotation of all the feeding pipes, the material can be stirred and fed by the feeding teeth, and the material can be dried and heated at the same time. Compared with the problem in the prior art that it is inconvenient to heat the material during the feeding process when the dryer is used, thus affecting the subsequent drying work, the method proposed in the utility model stirs and feeds the material by the feeding teeth, and the material can be dried and heated at the same time. The material can be heated and dried while continuously feeding and discharging the material, thus realizing the continuity of the drying process and having high practicality.
