Description

Technical Field

[0001] The utility model relates to the technical field of suspension preheaters, in particular to a suspension preheater for cement production. Background Art

[0002] Cement becomes a slurry when mixed with water and hardens into a hard material after solidification. It is often mixed with stone and adhesives to make building materials, which are transported to various construction sites by mud tankers. The most common way to store this material is to fill nylon bags with cement powder.

[0003] In order to ensure that the cement powder is dry enough, it is necessary to use a suspension preheater during processing to blow away the accumulated powder. A mixture of airflow and powder can be formed inside the tank, and it is constantly churning up and down to dry out excess moisture. However, the number of suspension preheater tanks in the past was relatively small. If a certain volume of cement powder was to be contained at a time, it would put pressure on the device, and the blowing effect would be compromised. The internal environment was empty, and there was a lack of structure to limit and guide the movement of materials.

[0004] Now, a new type of cement production suspension preheater is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the inclined plates are arranged in a left-right staggered state, and the gauze allows hot air flow and materials to pass through.

[0010] Preferably, a leakage hole is provided inside the bottom end of the thinning frame, and the motor can control the crushing rod to rotate on the leakage hole of the thinning frame.

[0011] Preferably, a transverse frame is welded to the top end of the outer side of the shell, and the top of the transverse frame is covered with a cover plate, an air groove is welded on the top of the cover plate, a retention box body is welded between the two sides of the bottom of the cover plate, brackets are installed on both sides of the lower inside of the transverse frame, short air pipes are welded between the transverse frame and the first heating tank and the third heating tank, long air pipes are welded between the transverse frame and the second heating tank and the fourth heating tank, and blowers are respectively installed on the short air pipes and the long air pipes.

[0013] Preferably, an air hole is left at the bottom of the interception box body, and the air groove can connect the external environment with the horizontal frame.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the cement production suspension preheater not only improves the efficiency of material blowing and pre-processes the material, but also filters the airflow extracted from the outside;

[0015] (1) Inclined plates are installed on both sides of the first heating tank, the second heating tank, the third heating tank and the fourth heating tank. The cement material enters the fourth heating tank from the short pipe under the control of the feed pump body. Under the guidance of the upper material pump and the lower material pump, the material passes through the third heating tank, the second heating tank and the last first heating tank.

After multiple crushing processes, the uneven drying effect caused by the different sizes of the particles is avoided, and then the cement powder is injected into the fourth heating tank through the short pipe by the feed pump body;

[0017] (3) By welding a horizontal frame on the top of the outer shell, the gas extracted from the external environment by the blower will inevitably carry other impurities. After closing the cover, the interception box at the bottom is overlapped on the top of the bracket, and the air flow is injected into each tank in each shell through the long air pipe and the short air pipe. The gauze at the bottom of the interception box intercepts large particles of impurities to prevent other objects from mixing into the dry cement powder, thereby ensuring the purity of the internal material.
