[0001] The utility model relates to the technical field of cement production equipment, in particular to an automatic sewage discharge device for waste heat power generation in cement production. Background Art

[0002] Cement is a general term for cementitious materials used in civil engineering. According to different cementing properties, it can be divided into hydraulic cement and non-hydraulic cement. Cement is particularly suitable for special occasions such as making concrete, precast concrete, plain concrete, adhesives, etc. The existing cement production line can use the steam generated during cement production to achieve thermoelectric conversion to achieve the purpose of power generation, which meets the requirements of energy conservation and environmental protection.

[0003] Existing thermoelectric conversion equipment still has certain shortcomings. During use, dust mixed in the steam can easily adhere to the thermoelectric material, resulting in a decrease in thermoelectric conversion efficiency.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3The utility model provides a technical solution: an automatic sewage discharge device for power generation from waste heat in cement production, comprising an air inlet pipe 1 and an air outlet pipe 2, characterized in that a filter component for filtering steam is provided between the air inlet pipe 1 and the air outlet pipe 2, the filter component comprising a filter cartridge 3, a filter screen plate 6 is provided inside the filter cartridge 3, a cleaning component for cleaning the filter screen plate 6 is provided inside the filter cartridge 3, a material guide pipe is provided at the bottom of the filter cartridge 3, a collection box is screwed on the bottom of the material guide pipe through a thread, so as to centrally collect the cleaned dust.

[0023] The cleaning component includes a mounting plate 4 fixedly arranged on the inner wall of the filter cartridge 3, a rotating rod 5 is rotatably penetrated on the mounting plate 4, the other end of the rotating rod 5 also rotates to penetrate the filter screen plate 6 and extends to the other end, and a fan blade is sleeved on the end of the rotating rod 5 away from the air intake pipe 1, wherein the rotating rod 5 can also be driven to rotate by an external motor, and a cleaning rod 7 is also sleeved on the rotating rod 5, and the cleaning rod 7 is in contact with the end surface of the filter screen plate 6 close to the air intake pipe 1.

[0024] A push rod 8 is movably provided on the surface of the mounting plate 4 , and a limiting ring is sleeved on the surface of the push rod 8 . A spring 9 is sleeved on the portion of the push rod 8 between the limiting rings.

[0025] An arc chamfer is provided at one end of the push rod 8 close to the filter screen plate 6, and an inclined chamfer matching with the push rod 8 is provided on one side of the cleaning rod 7, so as to facilitate squeezing the push rod 8 after the cleaning rod 7 abuts against the push rod 8.

[0026] Working principle: During use, when the steam generated in the cement production process is collected, the steam enters the air inlet pipe 1, and then the steam is filtered by the filter plate 6 and impacts the fan blades, thereby driving the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the cleaning rod 7 can be driven to make a circular motion around the filter plate 6, thereby cleaning the dust on the surface of the filter plate 6 to prevent the filter plate 6 from being blocked. At the same time, during the rotation of the cleaning rod 7, it will intermittently abut against the push rod 8, thereby squeezing the push rod 8 and compressing the spring 9. When the cleaning rod 7 is separated from the push rod 8, the push rod 8 is reset under the action of the spring 9, thereby hitting the filter plate 6, producing a knocking effect on the filter plate 6, and assisting the dust on the surface of the filter plate 6 to fall off. The fallen dust is finally collected by the collection box, which is convenient for subsequent centralized processing.
