[0002] A mixer is a mixing and molding machine that can mix multiple materials and make them into certain granular shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. In many applications, such as fertilizers, medicines, food and other fields, materials need to be mixed and made into granules first.

[0003] In the prior art, a typical mixer is a vertical mixer. The structure of a vertical mixer includes a base, a frame arranged above the base, a mixer barrel rotatably arranged on the base, and a barrel cover fixed on the upper part of the frame for covering the upper end of the mixer barrel; a number of mixer rotors extending into the mixer barrel are arranged on the barrel cover. In order to realize the rotation of the mixer barrel and the mixer rotor, a reduction motor for driving the mixer rotor to rotate is usually arranged on the barrel cover of the mixer, and a reduction motor for driving the mixer barrel to rotate is arranged at the lower part of the frame. During operation, the mixer barrel and the mixer rotor rotate separately, thereby realizing the mixing of materials inside the mixer barrel.

[0004] However, the existing vertical mixers still have the following shortcomings: after the discharge door has been used for a period of time, materials will adhere to and accumulate on the front side of the discharge door (the side inside the cylinder), and these materials may cause the properties of the materials to change after long-term accumulation on the discharge door, thereby affecting the mixing quality of the materials in the cylinder; on the other hand, the materials accumulated on the discharge door will also affect the sealing reliability when the discharge door is closed. In addition, for some materials with special requirements, it may be necessary to remove the adhered materials after each discharge to ensure the quality of the next batch of materials.

[0005] In view of the above problems, the discharge door is currently cleaned regularly by manual operation. The disadvantages are low efficiency and high labor intensity. In addition, manual cleaning of materials with odor will affect the health of operators. Utility Model Content
