[0002] In rotary drying equipment, the main function of the feed device is to feed the material to be dried into the dryer cylinder stably and continuously. The smooth progress of this process is crucial to ensure the drying effect, prevent material blockage and increase the service life of the equipment.
[0003] With the continuous development of drying technology, the feeding device of rotary drying equipment is also constantly innovating and optimizing. Traditional feeding methods may have problems such as uneven material distribution and blockage, which affects the drying effect and production efficiency. At present, there are many new types of rotary drying equipment feeding devices on the market, such as spiral feeding devices, vibration feeding devices, etc. However, when these feeding devices transport materials into the furnace, for materials with strong viscosity (such as ammonium chloride), it is very easy to cause problems such as scarring in the furnace, uneven materials, material blockage, and poor material reaction effect during the feeding process. In severe cases, it will cause the equipment to fail to operate normally. Utility Model Content

[0006] Furthermore, the rotary drying equipment furnace body is provided with a heating tube, and the heating tube is extended into the transition chamber to form a heating tube, so as to heat the inside of the transition chamber, without setting up a heating system separately.
[0007] Furthermore, the rotary drying equipment furnace has a built-in heating tube arranged on the inner wall of the furnace body, and the inner end of the built-in heating tube on the inner wall of the furnace body extends to the inner wall of the transition chamber, thereby better heating the transition chamber.

The outer end of the steam inlet shaft extends outside the furnace body and is rotatably arranged in the steam inlet box to provide a heat source for the heating tube.
[0009] Furthermore, a support plate is fixed to the inner wall of the furnace body, and a hole adapted to the self-contained heating tube is opened on the support plate to support and fix the self-contained heating tube, thereby achieving effective fixation of the self-contained heating tube.
[0010] Furthermore, a plurality of the copying plates are evenly arranged in the transition cavity, thereby improving the material conveying effect and preventing adhesion.
[0011] Furthermore, the lifting plates are distributed in a rotating spiral shape, which is convenient for conveying materials.
[0012] Furthermore, a plurality of chains are provided, each of which is arranged between the copying plates and cooperates with the copying plates to prevent the materials from sticking.
[0013] Furthermore, each set of chains and copy boards are arranged in an alternating manner.
[0014] Furthermore, each chain group includes at least two chains, and the chains are interlaced head to tail. When the drum rotates, the chains are driven to swing, and the bonding materials on the copy board and the inner wall are timely knocked off by the chains to prevent bonding.
[0015] Furthermore, both ends of the chain are fixedly connected to the inner wall of the transition cavity to form a flexible U-shaped structure to prevent the chains from being entangled with each other.
[0016] Furthermore, an air blowing channel is provided at the feeding end of the furnace body of the rotary drying equipment, and the air blowing channel leads to the material falling place at the front end of the transition zone.
[0017] The beneficial effects of adopting this technical solution are:

The drying equipment is enlarged, the production capacity is further increased (up to 500,000 tons / year), and energy conservation and emission reduction are achieved.
[0019] (2) The utility model adopts a spacer structure and utilizes the heating tubes in the furnace body to complete the heat supply, so as to appropriately raise the temperature of the low-temperature materials in the furnace head, and at the same time increase the overall temperature of the transition zone, reduce the condensation of the dried water, and reduce the adhesion of the materials.
