Description

[0002] Drying and grinding integrated equipment is an efficient solution for material handling in industrial production. It combines the drying and grinding processes of materials and is usually used in industries such as mining, chemicals, food, and pharmaceuticals. This type of equipment is designed to improve production efficiency, reduce intermediate processing steps, save energy, and simplify operating procedures.

[0003] The existing drying and grinding equipment either dries the material first and then grinds it, or grinds the material first and then dries it. If the first method is adopted, since the material has a certain block structure when drying, it takes a long time to dry the crushed material, which easily causes energy waste. If it is ground first and then dried, the wet material is easy to adhere to the grinding disc during grinding, which can easily cause the grinding mechanism to be blocked, or the ground material can clump, which can easily lead to uneven drying of the ground material.

An installation cavity is opened inside the bottom end of the crushing shaft, and the electric support rod is rotatably installed in the installation cavity through a bearing. The bottom end surface of the piston rod of the electric support rod is connected to the top of the upper hemisphere, and the lower end surface of the lower hemisphere is fixed with a supporting shaft rod, and the supporting shaft rod passes downward through the drying and discharging mechanism, and the bottom of the supporting shaft rod is connected to the piston rod of the vertically fixed electric lifting rod. The corresponding wall surfaces of the upper hemisphere and the lower hemisphere are opened with square holes, and a square strip is slidably inserted in the square hole, and the upper and lower end surfaces of the square strip are respectively connected to the hole walls of the upper and lower square holes through springs.

[0007] The cam is an axially rotatable conveyor belt of the invention and is adapted to move the camshafts and the camshafts together to form a rotational movement of the camshafts.

[0008] Furthermore, an annular boss is formed inside the bottom of the drying cylinder, and the slope of the annular boss is inclined toward the wall of the drying cylinder, and the bottom of the annular boss is aligned with the discharge pipe.

[0009] Furthermore, the frame includes a support plate, support legs, a connecting plate, a support rod and a threaded rod. The support plate is fixedly installed on the outer ring surface of the drying cylinder, and a plurality of support legs are fixed to the lower surface of the support plate. The connecting plate is fixedly installed on the crushing cylinder, and connecting holes are provided at corresponding positions of the connecting plate and the support plate. A plurality of support rods are arranged between the connecting plate and the support plate, and threaded rods are fixed at both ends of the plurality of support rods. The threaded rods at both ends pass downward through the connecting holes and are fixed to the support plate and the connecting plate through nuts.

[0010] Furthermore, a metal sleeve is insulated and installed at the center of the spiral blade, and the metal sleeve is sleeved on the stirring shaft tube, and an electromagnetic suction strip is also insulated and installed on the outer ring surface of the stirring shaft tube.

The crushed material in the crushing cylinder will fall into a spherical shell formed by connecting a hemispherical upper shell and a hemispherical lower shell. Then, the grinding balls are rotated, and the ball wall of the grinding balls and the spherical shell are provided with electric heating wires, so that the uniform block material can be ground and pre-dried at the same time, reducing the phenomenon that the wet material adheres to the inner wall of the spherical shell or the ball wall surface of the grinding ball during grinding, thereby reducing the phenomenon that the grinding pre-drying mechanism is blocked when grinding the crushed material.

[0013] The present invention divides the grinding ball into an upper hemisphere and a lower hemisphere, and the two can separate and slide up and down in the spherical shell. When the crushing cylinder crushes the material, the spherical surface of the upper hemisphere can slide upward and seal to the lower barrel mouth of the crushing cylinder to achieve the sealing of the crushing cylinder, so that the multiple crushing knives in the crushing cylinder can fully crush the material. When the crushed material is ground, the upper hemisphere and the lower hemisphere will be connected to form a complete grinding ball, so that the uniformly crushed material can be ground and pre-dried. When the ground material falls into the drying cylinder, the upper hemisphere and the lower hemisphere move upward at the same time, the upper hemisphere will seal the lower barrel mouth of the crushing cylinder, and the lower hemisphere will seal the upper barrel mouth of the drying cylinder, so that the drying cylinder can fully turn over and dry the powder after grinding and pre-drying. The upper hemisphere and the lower hemisphere can not only grind and pre-dry the crushed material, but also act as seals to seal the crushing cylinder and the drying cylinder respectively, so that both can fully process the material to be dried and ground.
