Description

Technical Field

[0001] This utility model relates to the technical field of cyclone separators for pulverizers, and in particular to a cyclone separator for pulverizers that uses air cooling. Background Technology

[0002] In existing cyclone separator technology for pulverizers, the cyclone separator, as a device that uses the centrifugal force generated by rotating airflow to separate materials from gas, is widely used in various pulverizing processes. It can effectively separate pulverized materials from the airflow to achieve the purpose of gas-solid separation.

[0003] However, in actual operation, traditional cyclone separators for pulverizers have significant shortcomings in cooling. As a large amount of heat is generated during the pulverization process, this heat causes the temperature inside the cyclone separator to rise sharply. The high temperature environment has a negative impact on the pulverization effect. Excessive temperature may alter the properties of the material, affecting the quality and performance of the product. At the same time, high temperature also increases the viscosity of the material, making it easier for the material to adhere inside the cyclone separator, causing blockage and reducing separation efficiency and production efficiency. Therefore, a cyclone separator for pulverizers with air cooling is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cyclone separator for a pulverizer that uses air cooling to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a cyclone separator for a pulverizer using air cooling, comprising a support frame, a conical tube fixedly installed inside the support frame, and a cyclone separator cylinder fixedly installed at the upper end of the conical tube. A protective structure is provided at the bottom of one end of the conical tube. A temperature sensor is fixedly installed on the outer wall of the cyclone separator cylinder. An air inlet pipe is fixedly installed at the upper end of the outer wall of the cyclone separator cylinder, and an exhaust pipe is fixedly installed at the upper end of the cyclone separator cylinder. A cyclone separation chamber is opened inside the cyclone separation chamber. A heat dissipation structure is provided on the inner wall of the cyclone separation chamber. The heat dissipation structure includes an air inlet fixedly installed at the bottom of the outer wall of the cyclone separator cylinder. A spiral cooling air duct is fixedly connected to one end of the air inlet. Multiple heat dissipation fins are provided on the outer wall of the cooling air duct. An exhaust pipe is fixedly installed at one end of the cooling air duct, and a cooling fan is provided inside the exhaust pipe.

[0006] As a preferred embodiment of the above technical solution, a dust filter plate is fixedly installed inside the air inlet, the cooling air duct is adapted to the size of the cyclone separator, and the heat dissipation fins are evenly distributed on the inner wall of the cyclone separator and are tightly fitted with the cooling air duct.

[0007] As a preferred embodiment of the above technical solution, the exhaust pipe passes through the upper end of the cyclone separator, the upper end of the cooling fan is fixedly connected to the micro motor, and the micro motor is fixedly installed at the bottom of the filter louvers.

[0008] As a preferred embodiment of the above technical solution, the filter louvers are fixedly installed on the inner wall of the exhaust pipe, and a discharge port is fixedly provided at one end of the tapered pipe.

[0009] As a preferred embodiment of the above technical solution, the protective structure includes a fixing collar fixedly installed on the outer wall of the discharge port, and a limit rod is fixedly provided on the outer wall of the fixing collar, and a guide plate is rotatably frictionally mounted on the outer wall of the limit rod.

[0010] As a preferred embodiment of the above technical solution, the other end of the guide plate has a fixed rod that rotates by friction, and the outer wall of the fixed rod is fixedly installed on the outer wall of the dust cover, and the dust cover is adapted to the size of the discharge port.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with a heat dissipation structure. When the cooling fan is driven by a micro motor, cold air from the outside is drawn into the cooling air duct through the air inlet. At the same time, impurities and pollutants from the outside are intercepted and filtered by the dust filter plate. The cold air flows along the spiral cooling air duct and heat dissipation fins. During the flow, the cold air continuously absorbs the heat transferred from the outer wall of the cyclone separation chamber and is then discharged from the filter louvers on the exhaust pipe of the cooling fan. This is beneficial for the air cooling and cooling of the cyclone separator. Effective cooling can prevent changes in the properties of materials during crushing and separation, ensuring the original characteristics and quality of the materials. For the equipment itself, lowering the temperature can slow down the wear and aging of equipment parts, extend the service life of the equipment, and reduce the probability of equipment failure.

[0013] 2. The device of this utility model is equipped with a protective structure. By rubbing the guide plate at both ends with the limiting rod and the fixing rod on the fixing collar, the dust cover is rotated at multiple angles and connected with the discharge port. This helps to seal and protect the discharge port when the cyclone separator is not in use, prevent dust from entering and affecting its later use, and improve its protection.

It should be understood that the embodiments of the present invention are not limited in scope. Within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications, and equivalents. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this embodiment provides a cyclone separator for a pulverizer that uses air cooling. It includes a support frame 1, a conical tube 9 fixedly installed inside the support frame 1, and a cyclone separator cylinder 2 fixedly installed at the upper end of the conical tube 9. A protective structure 7 is provided at the bottom of one end of the conical tube 9. A temperature sensor 8 is fixedly installed on the outer wall of the cyclone separator cylinder 2. An air inlet pipe 3 is fixedly installed at the upper end of the outer wall of the cyclone separator cylinder 2, and an exhaust pipe 4 is fixedly installed at the upper end of the cyclone separator cylinder 2. A cyclone separation chamber is opened inside the cyclone separation chamber. A heat dissipation structure 6 is provided on the inner wall of the cyclone separation chamber. The heat dissipation structure 6 includes an air inlet 61 fixedly installed at the bottom of the outer wall of the cyclone separator cylinder 2. A spiral cooling air duct 63 is fixedly connected to one end of the air inlet 61. Multiple heat dissipation fins 64 are provided on the outer wall of the cooling air duct 63. An exhaust pipe 65 is fixedly installed at one end of the cooling air duct 63, and a cooling fan 66 is provided inside the exhaust pipe 65.

[0023] like Figures 2 to 3 As shown, a dust filter plate 62 is fixedly installed inside the air inlet 61. The cooling air duct 63 is adapted to the size of the cyclone separator 2. The heat dissipation fins 64 are evenly distributed on the inner wall of the cyclone separator and are tightly fitted with the cooling air duct 63. The exhaust pipe 65 passes through the upper end of the cyclone separator 2. The upper end of the cooling fan 66 is fixedly connected to the micro motor 67. The micro motor 67 is fixedly installed at the bottom of the filter louvers 68. The filter louvers 68 are fixedly installed on the inner wall of the exhaust pipe 65. A discharge port 5 is fixedly provided at one end of the tapered pipe 9.

[0024] The air inlet pipe 3 is located on the side of the cyclone separator 2, entering tangentially. This allows the airflow containing material particles to generate a strong rotational motion upon entering the cyclone separator chamber. The cyclone separator chamber is the core component of the entire equipment, made of high-strength metal material, possessing excellent wear resistance and sealing performance. The exhaust pipe 4 is located at the top center of the cyclone separator chamber, through which the clean gas after separation is discharged. The dust collection area is located at the bottom of the cyclone separator chamber in a funnel shape, used to collect the separated material particles. A discharge port is located at the bottom of the dust collection area. 5. Facilitating material discharge: The cooling air duct 63 surrounds the outer wall of the cyclone separation chamber in a spiral shape. One end of the duct is open to the outside atmosphere, and the other end is connected to the exhaust pipe 65 of the cooling fan 66. The cooling fan 66 is installed at the air outlet of the cooling air duct 63. It is an axial flow fan with the characteristics of large air volume and low air pressure, which can generate a strong airflow to drive the air flow in the cooling air duct 63. The heat dissipation fins 64 are evenly distributed on the outer wall of the cyclone separation chamber and are closely attached to the cooling air duct 63, which increases the heat dissipation area and improves the heat dissipation efficiency.

[0025] like Figure 4 As shown, the protective structure 7 includes a fixing ring 71 fixedly installed on the outer wall of the discharge port 5. A limiting rod 72 is fixedly provided on the outer wall of the fixing ring 71, and a guide plate 73 is rubbed and rotated on the outer wall of the limiting rod 72. A fixing rod 74 is rubbed and rotated on the other end of the guide plate 73. The outer wall of the fixing rod 74 is fixedly installed on the outer wall of the dust cover 75. The dust cover 75 is adapted to the size of the discharge port 5.

[0026] By rubbing against the limiting rod 72 and the fixing rod 74 on the fixed collar 71 at both ends of the guide plate 73, the dust cover 75 is rotated at multiple angles and connected with the discharge port 5 for installation, thereby sealing and protecting the discharge port 5 and preventing dust from entering and affecting its later use.

[0027] The working principle and operation process of this utility model are as follows: Before starting the equipment, the operator needs to conduct a comprehensive inspection to check whether there are any foreign objects inside the cyclone separator 2. If so, clean them in time to ensure that the airflow channel is unobstructed. Then, when starting the equipment, first turn on the cooling fan 66 and let it run for a period of time to form a stable airflow in the cooling air duct 63, preparing for the equipment to cool down. Then, start the crusher connected to the cyclone separator, and introduce the airflow containing material particles into the cyclone separation chamber through the air inlet 3. During normal operation, observe the rotation of the airflow in the cyclone separation chamber and the separation effect of the material through the observation window to ensure that the airflow is stable and the material can be separated smoothly. At the same time, monitor the temperature of the equipment through the temperature sensor 8 to ensure that the temperature is within the normal range. If the temperature is found to be too high, the cooling fan 66 can be adjusted appropriately. The rotation speed of 6 increases the cooling air volume to reduce the equipment temperature. When the micro motor 67 drives the cooling fan 66 to rotate, cold air from the outside is drawn into the cooling air duct 63 through the air inlet 61. At the same time, impurities and pollutants from the outside are intercepted and filtered by the dust filter plate 62. The cold air flows along the spiral cooling air duct 63 and the heat dissipation fins 64. During the flow, the cold air continuously absorbs the heat transferred from the outer wall of the cyclone separator and is then discharged from the filter louvers 68 on the exhaust pipe 65 of the cooling fan 66, thereby achieving air cooling of the cyclone separator. When the cyclone separator 2 is not in use, the guide plate 73 rotates around the limit rod 72, causing the guide plate 73 to drive the dust cover plate 75 on the fixed rod 74 to rotate and align with the discharge port 5, thereby protecting the discharge port 5 and preventing dust from entering and affecting the next use.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
