[0002] Due to its advantages such as small dielectric constant, low thermal expansion coefficient, small volume density, high specific strength and low sintering temperature, the application field of calcium stone is constantly expanding, such as the electronics industry, heat exchanger industry and biomedical materials.

[0003] In chemical plants, the mined calcium ore needs to be collected and transported to production equipment for processing, so a hopper is needed. The process of pouring calcium ore into the hopper and pouring calcium ore from the hopper to the conveyor belt often stirs up dust, causing environmental pollution. Long-term inhalation of dust will also affect the health of operators. In addition, since the mined calcium ore is not uniform in size, subsequent processing requires sorting and crushing, and the existing hopper has a single function and is only used as a storage container. It neither fully utilizes the space nor is it conducive to improving production efficiency. Utility Model Content

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Example 1: Reference Figure 1-Figure 5 A dust-proof hopper for processing calcium stone includes a hopper 1, and also includes: a water pipe 2 fixedly connected to the top of the hopper 1, a nozzle 21 is installed on the water pipe 2, and water is sprayed to reduce dust during the feeding process; an air curtain machine 5 is installed on the discharge port 4, so that the dust during the discharge process is isolated inside the hopper 1 by the air curtain; an air outlet 51 is opened inside the discharge port 4, and a protective net 52 is installed inside the air outlet 51. The outer wall of the hopper 1 is designed with a reinforcing rib 14. The upper part of the hopper 1 is fixedly connected to a working platform 15.

[0024] The nozzle 21 installed on the water pipe 2 can spray water mist. In the process of feeding into the hopper 1, the dust generated by the collision of the calcium stone and the hopper 1 will be absorbed and settled by the water mist, and the air curtain machine 5 installed at the lower part of the hopper 1 can form an air curtain from the air outlet 51 inside the discharge port 4 to isolate the dust inside the hopper 1 to prevent the dust from scattering outward and affecting the environment and personnel health. The air outlet 51 is provided with a protective net 52 to prevent the calcium stone fragments from entering the air outlet 51. The outer wall of the hopper 1 is provided with reinforcing ribs 14 to strengthen the structural strength of the hopper 1. The operator can climb onto the working platform 15 through a ladder to observe the internal situation of the hopper 1.

[0025] Example 2: Reference Figure 1-Figure 5, a dust-proof hopper for processing calcium stone, which is basically the same as Example 1, and further: a rotating shaft 31 passes through the lower part of the discharge port 4, and a blade 36 is installed on the rotating shaft 31, and the calcium stone is crushed during the discharge process. The interior of the hopper 1 is slidably connected with a hatch 13, and the lower part of the hatch 13 is fixedly connected with a hanging ear 35. A slide groove 11 is provided on the hopper 1, and the hanging ear 35 passes through the hopper 1 by the slide groove 11 and is slidably connected with the slide groove 11. A through hole is provided on the hanging ear 35, and a connecting shaft 34 passes through the through hole and is rotatably connected with the hanging ear 35. The connecting shaft 34 is rotatably connected to one end of the connecting rod 33, and the other end of the connecting rod 33 is rotatably connected to the rocker arm 32, and the rocker arm 32 is fixedly connected to the rotating shaft 31.

[0026] The motor 3 is connected to the rotating shaft 31 in transmission, and the rotating shaft 31 is driven by the motor 3 to rotate, driving the blade 36 installed on the rotating shaft 31 to rotate, breaking the calcium stone ores of different sizes into pieces of uniform size and then discharging them through the discharge port 4. The circular motion of the rotating shaft 31 is converted into linear motion through the rocker arm 32, the connecting rod 33, and the connecting shaft 34, thereby pushing the reciprocating movement of the hatch 13 to realize the opening and closing of the hatch 13, thereby controlling the discharge speed of the calcium stone and preventing the discharge port 4 from being blocked. Baffles 12 are provided on both sides of the hatch 13 to prevent smaller calcium stones from falling out of the hopper 1 through the chute 11.

[0027] The utility model sprays water mist through a water pipe 2 fixedly connected to the top of the hopper 1 to settle the raised dust. A blade 36 is arranged in the discharge port 4 to crush calcium ore of different sizes to obtain fragments of uniform size, which is convenient for subsequent processing. The dust generated during the working process of the blade 36 is isolated in the hopper 1 by the wind curtain of the discharge port 4 to prevent the dust from floating outward. The door 13 in the hopper 1 is driven to open and close by the power of the rotating shaft 31 of the blade 36, so as to control the material discharge speed and avoid material blockage in the hopper 1.
