Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide processing technology, specifically to a powder selection device for calcium hydroxide production and preparation process. Background Technology

[0002] Calcium hydroxide, commonly known as slaked lime or quicklime, is a white powdery solid that is slightly soluble in water. Calcium hydroxide is a strong alkali with bactericidal and antiseptic properties, but it is corrosive to skin and fabrics. Calcium hydroxide has a wide range of industrial applications and is often used in the manufacture of bleaching powder, disinfectants, insecticides, and building materials.

[0003] A search revealed that CN217432288U describes a powder classifier for producing calcium hydroxide. This device includes a powder classifier housing and three fans, each fixedly connected to the inner wall of a small particle passage. When powder classification of calcium hydroxide particles of varying sizes is required, the calcium hydroxide raw material is first poured into the powder classifier cylinder through the feed inlet of the small particle passage. Then, the motor is started, and its output shaft drives a rotating rod, which in turn rotates the powder classifier cylinder at the lower end of the rod. The calcium hydroxide raw material inside the powder classifier cylinder splashes outwards, impacting the inner wall of the small particle passage, and then falls into the inclined separating plate for collection. During the falling process, the baffle plate is activated to blow smaller pieces of calcium hydroxide raw material into the small particle passage for separation. This effectively improves the efficiency of the powder classification operation, enhances the performance, and simplifies operation.

[0004] However, the above-mentioned powder classifier still has the following problems: the powder classifier performs powder classification of calcium hydroxide through a single powder classifier cylinder, but the agglomeration of the powder classifier cylinder after high-speed rotation will block the holes of the powder classifier cylinder, thereby affecting the screening of the powder classifier cylinder, and the powder classifier is inconvenient to control the conveying volume when conveying raw materials. Utility Model Content

[0005] This invention proposes a powder selection device for the production and preparation process of calcium hydroxide, which solves the problems of clogging of the powder selection cylinder caused by agglomerated particles and inconvenience in quantitative conveying.

[0008] Preferably, the export component includes an export frame, which is fixedly connected to the middle of the inner bottom wall of the mounting frame. A second motor is fixedly connected to one side of the inner wall of the export frame, and a movable shaft is fixedly connected to one end of the output shaft of the second motor. A spiral guide plate is fixedly connected to the outer side of the movable shaft.

[0009] Preferably, a discharge pipe is fixedly connected to one side of the bottom end of the spiral guide plate, and the bottom end of the discharge pipe passes downward through the bottom of the mounting frame.

[0010] Preferably, the conveying assembly includes a fixed frame, which is fixedly connected to one side of the inner top wall of the mounting frame. Conveying rollers are rotatably connected to both sides of the inner wall of the fixed frame. A conveyor belt is fitted on the outer side of the two conveying rollers. A third motor is fixedly connected to one side of the fixed frame, and one end of the output shaft of the third motor is fixedly connected to the conveying rollers.

[0011] Preferably, the top of the inner wall of the fixed frame is rotatably connected to a support roller arranged at equal intervals, and the top of the support roller is rolledly connected to the inner wall of the conveyor belt.

[0012] Preferably, support rods are fixedly connected to the four corners of the bottom end of the mounting frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, calcium hydroxide can be transported into the powder classifier through the storage cylinder and the conveying component. The powder classifier is driven to rotate at high speed by the first motor, which can screen the calcium hydroxide. The double-layer setting of the powder classifier can prevent clogging during the powder classification process, thus solving the problem of clogging that is common in existing powder classifiers.

[0015] 2.

The screened calcium hydroxide powder can be conveyed downward through the guide frame, and the powder can be discharged outward through the discharge component, thus solving the problem of inconvenient quantitative conveying in existing powder classifiers.
