[0006] This utility model provides a cement clinker cooling device for cement production, which solves the problems of the prior art's cooling device, which uses natural cooling of cement clinker and cannot form air convection in the mixing chamber, resulting in low cooling efficiency of cement clinker and dust being scattered in the external environment, causing poor environmental performance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cement clinker cooling device for cement production includes a base. A transmission mechanism is located on the top of the base. The transmission mechanism includes a mounting seat fixed to the outer wall of the top of the base, a drive motor bolted to the lower outer wall of one side of the mounting seat, and a fixing seat fixed to the outer wall of the top of the base. A conveying assembly is located on one side of the mounting seat. The conveying assembly includes a conveying cylinder, spiral blades fixed to the inner wall of the conveying cylinder, and a heat exchange cylinder sleeved within the spiral blades. The heat exchange cylinder contains several heat exchange components, each including an arc-shaped heat exchange plate and several heat dissipation fins respectively fixed to the inner wall of the heat exchange plate. A feeding assembly is located at one end of the heat exchange cylinder. A heat dissipation assembly is located inside the heat exchange cylinder, and the heat dissipation assembly includes components bolted to the inner wall of one end of the heat exchange cylinder. The base includes an installation ring and a cooling fan bolted to the outer wall of one side of the installation ring. The top of the base is equipped with a collection mechanism, which includes a collection box with a through hole on the upper outer wall of one side, a partition fixed to the inner wall of the middle of the collection box, and a centrifugal fan bolted to the upper outer wall of one side of the collection box. The collection box is equipped with a filter assembly, which includes an installation frame abutting against the top outer wall of the partition, a filter screen embedded in the installation frame, four sliding rods that pass through and slide on the outer wall of the installation frame, and four return springs that are respectively sleeved on the outer walls of the four sliding rods. A vibration assembly is provided on one side of the installation frame, which includes a cleaning motor bolted to the outer wall of one side of the collection box and two cams abutting against the outer wall of one side of the installation frame.

[0009] Preferably, a fixing cylinder is fixed on the upper outer wall of one side of the mounting base, and one end of the output shaft of the transmission motor is connected to a rotating shaft through a coupling, and one end of the rotating shaft is connected to a gear through a pin.

[0010] Preferably, one end of the conveying cylinder is connected to the inside of the fixed cylinder through a bearing, and the other end of the conveying cylinder passes through and is connected to the outer wall of the fixed base through a bearing. A toothed ring is connected to the outer wall of one end of the conveying cylinder through a pin, and the toothed ring meshes with a gear to form a transmission fit. One end of the heat exchange cylinder passes through and is fixed to the outer wall of the mounting base.

[0011] Preferably, the heat exchange cylinder has equally spaced mounting slots, and the heat exchange plate is embedded in the mounting slots.

[0012] Preferably, the feeding assembly includes a fixed plate bolted to the outer wall of one side of the mounting base, a conveying pipe that penetrates and is fixed to the outer wall of the fixed plate, a feeding hopper fixed to the upper inner wall of the conveying pipe, a feeding motor bolted to the outer wall of one side of the conveying pipe, an auger connected to one end of the output shaft of the feeding motor via a coupling, and a discharge pipe fixed to the lower inner wall of the conveying pipe. The outer wall of the fixed plate has several air inlets, one end of the auger penetrates and is connected to the outer wall of the conveying pipe via a bearing, and the lower part of the discharge pipe penetrates and is fixed to the outer wall of the heat exchange cylinder.

[0013] The above scheme involves a feeding motor driving an auger to rotate, conveying cement clinker into the space between the conveying cylinder and the heat exchange cylinder. The output shaft of the drive motor drives a gear to rotate, which in turn drives a gear ring, the conveying cylinder, and the spiral blades to rotate. The spiral blades convey the cement clinker, and during the conveying process, the cement clinker exchanges heat with the heat exchange cylinder. At the same time, the heat exchange plate transfers heat to the heat sink, and the cooling fan draws outside air into the heat exchange cylinder. The outside air then transfers the heat from the heat sink to the outside of the heat exchange cylinder.

[0014] Preferably, the mounting frame is slidably fitted inside the collection box, and one end of each of the four sliding rods is fixed to the inner wall of one side of the collection box, and a limiting block is fixed to one end of each of the four sliding rods.

The two cams are respectively connected to the outer walls of both ends of the drive shaft via pins.

[0016] The above scheme uses a centrifugal fan to draw hot air from one end of the heat exchange cylinder and dust from the cement clinker at the other end of the conveying cylinder into a collection box. The filter screen filters the dust, and the motor output shaft drives the transmission shaft and two cams to rotate. The two cams squeeze the mounting frame, causing the mounting frame to reciprocate under the squeezing of the cams and the tension of multiple sets of return springs, shaking the dust on the filter screen into the collection box. At the same time, the moving mounting frame pushes the dust on the partition plate.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The feeding motor drives the auger to rotate, conveying cement clinker into the space between the conveying cylinder and the heat exchange cylinder. The output shaft of the drive motor drives the gear to rotate, which in turn drives the gear ring, the conveying cylinder and the spiral blades to rotate. The spiral blades convey the cement clinker. During the conveying process, the cement clinker exchanges heat with the heat exchange cylinder. At the same time, the heat exchange plate transfers heat to the heat sink. The cooling fan draws outside air into the heat exchange cylinder, and the outside air transfers the heat from the heat sink to the outside of the heat exchange cylinder. This conveys the cement clinker, ensuring that the cement clinker is in full contact with the heat exchange cylinder, thus fully cooling the cement clinker and improving the cooling efficiency.

[0019] 2. The centrifugal fan operates, drawing hot air from one end of the heat exchange cylinder and dust from the cement clinker at the other end of the conveying cylinder into the collection box. The filter screen filters the dust, and the motor output shaft drives the transmission shaft and two cams to rotate. The two cams press against the mounting frame, causing the mounting frame to reciprocate under the pressure of the cams and the tension of multiple sets of return springs, shaking the dust on the filter screen into the collection box. At the same time, the moving mounting frame pushes the dust on the partition plate, which can collect and filter the dust generated during unloading, preventing dust from drifting into the external environment and improving environmental protection.

[0020] In summary, this utility model can transport cement clinker, allowing it to fully contact the heat exchange cylinder and thus fully cool it, improving cooling efficiency. It can also collect and filter the dust generated during unloading, preventing dust from drifting into the external environment and improving environmental friendliness. Attached Figure Description
