Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high-temperature fan for a cement kiln in cement production. Background Art

[0002] At present, high-temperature fans are usually needed in cement kilns. The main function of high-temperature fans in cement kilns is to provide air flow in high-temperature environments, reduce energy consumption, reduce emissions, improve production efficiency, and protect the environment. High-temperature fans in cement kilns play a vital role in industrial production, especially in cement clinker production lines. These fans can withstand high-temperature environments and are made of high-temperature resistant materials to ensure normal operation under high temperatures.

[0003] For example, Chinese patent announcement No. CN219549227U discloses an energy-saving cement kiln high-temperature fan. When in use, the base, mounting seat, damper, and shock-absorbing spring are used in combination to effectively buffer and damp the fan body on the base, thereby reducing the vibration generated by the fan body during use, reducing the adverse effects of the vibration on the fan body, facilitating the improvement of the stability of the fan body during use, reducing the mechanical wear of the fan body during use, and helping to extend its service life. When the fan body fails and needs to be disassembled and repaired, the pull rod is pulled so that the positioning block at one end of the pull rod is away from the positioning grooves on the surfaces of both sides of the fan body. The fan body is removed from the base by moving the fan body upward so that the fan body is away from the enclosure on the base, thereby facilitating the staff to disassemble and repair the fan body, reducing the disadvantages during use, and helping to improve its practicality.

[0004] However, the energy-saving cement kiln high-temperature fan in the above application only provides buffering and shock reduction for the fan during operation, and has a low overall thermal energy utilization rate for the cement kiln, and the energy-saving and environmental protection effect is not significant. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a cement kiln high temperature fan for cement production. Utility Model Content

[0006] The utility model aims to provide a high-temperature blower for a cement kiln in cement production, so as to solve the problem that the energy-saving high-temperature blower for a cement kiln proposed in the above-mentioned background technology only provides buffering and shock reduction for the blower during operation, and the overall thermal energy utilization rate of the cement kiln is low, and the energy-saving and environmental protection effect is not significant.

[0007] To achieve the above objectives, the utility model provides the following technical solutions: a high-temperature blower for a cement kiln for cement production, comprising a blower body and a connecting pipe, wherein the connecting pipe is installed on the blower body, and a preheating device is arranged on the connecting pipe.

[0008] The preheating device includes a return pipe, a mounting block, a tension spring, a dust filter, a vibration assembly, and a dust collecting assembly. The return pipe is fixedly connected to the left side of the connecting pipe. Four mounting blocks are respectively installed at the four corners of the inner wall of the return pipe. Four tension springs are respectively fixedly connected to the left side of the mounting block. The dust filter is installed at the left end of the tension spring. The vibration assembly is installed on the front of the return pipe. The dust collecting assembly is installed at the bottom of the return pipe. When the fan body blows the external airflow into the interior of the cement kiln through the connecting pipe, the airflow flows through the connecting pipe at a high speed. According to the Bernoulli principle, the hot air inside the cement kiln is sucked into the interior of the connecting pipe through the return pipe, so that the hot air inside the cement kiln is used to quickly heat the airflow inside the connecting pipe, making full use of the waste heat inside the cement kiln, which is more energy-saving and efficient.

[0009] A further improvement is that the vibration component includes a sealed bearing, a rotating shaft, a turntable, and a protrusion. The sealed bearing is installed on the front side of the return pipe, the rotating shaft is rotatably connected to the inside of the sealed bearing, and its rear end extends into the inside of the return pipe. The turntable is fixedly connected to the front end of the rotating shaft, and the protrusion is fixedly connected to the rear end of the rotating shaft. In the process of hot air inside the cement kiln flowing into the connecting pipe through the return pipe, dust inside the cement kiln is inevitably brought into the inside of the connecting pipe. Therefore, the dust is intercepted and filtered through the dust filter. Regularly rotating the turntable can drive the rotating shaft to rotate inside the sealed bearing, thereby driving the protrusion to rotate and hit the dust filter, causing it to vibrate left and right under the pull of the tension spring, thereby shaking off the dust on its surface to prevent dust from clogging the dust filter and affecting the utilization of waste heat.

[0010] A further improvement is that the dust collecting assembly includes a guide rail, a dust collecting box, and a pull ring, the guide rail is fixedly connected to the bottom of the return pipe, the dust collecting box is slidably connected to the inside of the guide rail, and the pull ring is fixedly connected to the front center of the dust collecting box.

[0011] A further improvement is that the vibration component is located on the right side of the dust filter, and a dust discharge port is provided at the bottom of the return pipe, which is located below the dust filter. The dust collecting component is installed below the dust discharge port, and the shaken dust falls into the interior of the dust box through the dust discharge port. The dust box can be taken out from the inside of the guide rail for cleaning by regularly pulling the pull ring.

[0012] A further improvement is that the fan body includes a motor, a transmission member, a chassis, and fan blades, the motor is installed on the base, the transmission member is installed on the output end of the motor, the chassis is installed on the rear side of the transmission member, and the fan blades are installed inside the chassis and are connected to the rear end of the transmission member.

[0013] A further improvement is that an air inlet is opened on the back of the chassis, and a dust screen is installed inside the air inlet. The dust screen intercepts and filters dust in the external airflow to prevent a large amount of dust from entering the interior of the chassis.

[0014] A further improvement is that an exhaust duct is fixedly connected to the left side of the chassis, a connecting pipe is installed on the top of the exhaust duct, and an air supply duct is installed on the top of the connecting pipe. The starting motor drives the rotating shaft in the transmission member to rotate, and then drives the rotating shaft to rotate inside the bearing seat through the transmission belt, thereby driving the fan blades inside the chassis to rotate, sucking the external air into the interior of the chassis through the air inlet, and then sending it into the interior of the cement kiln through the exhaust duct, connecting pipe and air supply duct.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The high-temperature fan of the cement kiln produced by this cement, when the fan body blows the external airflow into the interior of the cement kiln through the connecting pipe, the airflow flows through the connecting pipe at a high speed, and according to the Bernoulli principle, the hot air inside the cement kiln is sucked into the interior of the connecting pipe through the return pipe, so that the hot air inside the cement kiln is used to quickly heat the airflow inside the connecting pipe, making full use of the waste heat inside the cement kiln, which is more energy-saving and efficient.

[0017] 2. The high-temperature fan of the cement kiln produced by this cement intercepts and filters the dust through the dust filter, and the regular rotation of the turntable can drive the rotating shaft to rotate inside the sealed bearing, thereby driving the protrusion to rotate and hit the dust filter, causing it to vibrate left and right under the pull of the tension spring, thereby shaking off the dust on its surface to prevent dust from clogging the dust filter and affecting the utilization of waste heat.

At the end, the vibration component 305 is installed on the front side of the return pipe 301, and the dust collecting component 306 is installed at the bottom of the return pipe 301. When the fan body 1 blows the external airflow into the interior of the cement kiln through the connecting pipe 2, the airflow flows through the connecting pipe 2 at a high speed.
