Description

Technical Field

[0001] The utility model belongs to the technical field of design of supporting facilities for gypsum production, and particularly relates to a high-efficiency grinding structure for gypsum production. Background Art

[0002] Gypsum is a common ore with a chemical composition of calcium sulfate hydrate, and its main component is calcium sulfate dihydrate (CaSO4·2H2O). Gypsum usually appears as colorless to white crystals or transparent, and is a very important industrial raw material. Gypsum has a wide range of uses in industry. First of all, it is an important building material and is widely used in construction. After mixing with water, gypsum can quickly solidify into a hard, volume-stable gypsum stone, so it is used for wall and ceiling decoration and lining. At the same time, gypsum can also be used to make gypsum boards for partitions and suspended ceilings. The flame retardant properties of gypsum make it an ideal building material. Gypsum also has important uses in agriculture. Gypsum can be used as a soil conditioner to improve soil structure and provide essential elements such as calcium and sulfur, thereby increasing soil fertility and improving the crop growth environment.

[0003] After gypsum is ground, the powder obtained needs to be screened. The existing grinding structure has a slow screening speed when screening the powder, and the powder is easy to accumulate, affecting the processing continuity. At the same time, the internal linkage of the device is low and the manufacturing cost is high. Summary of the invention

[0004] The purpose of the utility model is to provide a high-efficiency grinding structure for gypsum production to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-efficiency grinding structure for gypsum production comprises a box device, a power device is arranged in the middle of the box device, and a screening device is arranged at the bottom of the power device; the power device comprises two symmetrically arranged grinding rollers, a rotating shaft is arranged in the middle of the grinding rollers, a gear is arranged at the front end of the rotating shaft, a motor is arranged in front of the gear, a bracket is arranged behind the motor, a first pulley is arranged on one side of the bracket, a second pulley is arranged below the first pulley, and a belt is arranged between the first pulley and the second pulley; the screening device comprises a screening frame, a screen is arranged in the middle of the screening frame, two pulleys are arranged on one side of the screening frame for symmetrical rotation front and back, a cam is arranged at the bottom of the pulley, and a transmission shaft is arranged at the bottom of the cam.

[0007] Furthermore: the box device includes a processing box, a discharging inclined plate is fixedly arranged at the bottom of the processing box, and a feeding frame is fixedly arranged at the top of the processing box.

[0008] Furthermore: the discharging inclined plate is welded to the processing box.

[0009] Furthermore, the rotating shaft is connected to the processing box bearing, and the bracket is welded to the processing box.

[0010] Furthermore: the motor is connected to the rotating shaft with a flat key, and the motor is connected to the bracket with bolts.

[0011] Furthermore: the first pulley is connected to the rotating shaft with a flat key, and the second pulley is connected to the transmission shaft with a flat key.

[0012] Furthermore: the transmission shaft is connected to the processing box bearing, and the screening frame is hingedly connected to the processing box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The cam intermittently toggles the pulley when rotating, causing it to repeatedly move up and down under the action of the cam and its own gravity. During this process, the pulley drives the screening frame to vibrate regularly with the bottom of the processing box as the fulcrum, driving the screen to screen the gypsum powder. The sufficiently ground powder passes through the screen and falls on the discharging inclined plate and slides down to complete the discharging. The larger gypsum powder that does not meet the grinding standard slides down along the screen and finally leaves the processing box for subsequent reprocessing. The design of the cam driving the screen to vibrate facilitates the improvement of the screening speed, prevents the accumulation of gypsum powder, enhances the processing continuity, and enables the device to operate stably for a long time.

[0015] When the rotating shaft rotates, it synchronously drives the front and rear first pulleys to rotate. The first pulley drives the second pulley below to rotate through the belt. The second pulley drives the transmission shaft to rotate under the support of the processing box, so that the cam inside the transmission shaft rotates synchronously. By arranging the first pulley on the rotating shaft, the motor drives the grinding roller and the cam to rotate at the same time, thereby improving the linkage of the device and saving manufacturing costs.
