Description

Technical Field

[0001] The utility model belongs to the technical field of gas-solid separation, and specifically relates to a cyclone separator. Background Art

[0002] A cyclone separator is a commonly used environmental protection device for separating solid particle dust in a gas-fluid to purify the gas. The cyclone separator utilizes the rotational motion of a gas-solid two-phase fluid to separate the solid particle dust in the fluid from the gas stream under the action of centrifugal force. Most of the existing cyclone separators adopt a single-stage cyclone cylinder, and the separation efficiency is not high. In this case, some technicians design to simply connect two identical cyclone cylinders in series to improve the collection efficiency. However, since the first-stage cyclone cylinder has collected coarser particles, the particles in the dust entering the second-stage cyclone cylinder are much smaller than those in the first stage, and the second-stage cyclone cylinder cannot collect fine particles well, and the separation efficiency is not significantly improved. The low separation efficiency of the cyclone separator results in a large amount of dust not being collected, causing great wear or load to downstream equipment. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a cyclone separator, which includes a first separation cylinder, a second separation cylinder, an air inlet pipe, an exhaust pipe, and a dust hopper.

[0004] The first separation cylinder includes a first cylinder and a first cone cylinder fixedly connected to the bottom end of the first cylinder. The second separation cylinder includes a second cylinder and a second cone cylinder fixedly connected to the lower end of the second cylinder. The second separation cylinder is coaxially sleeved inside the first separation cylinder, and the top end of the second cylinder is fixedly connected to the top end of the first cylinder. The inner diameter of the smallest part of the second cone cylinder is greater than the outer diameter of the exhaust pipe.

[0005] The air inlet pipe is arranged on the outer side of the top of the first cylinder, and the air inlet pipe passes through the first cylinder and tangentially enters the second cylinder, and a condensing coil is sleeved on the pipe section of the air inlet pipe outside the first separation cylinder. The condensing coil is connected to a refrigerator through a pipeline; the exhaust pipe penetrates through the centers of the first separation cylinder and the second separation cylinder and extends to the lower side of the first cone cylinder, and a fan is arranged in the pipe section of the exhaust pipe outside the first separation cylinder.

[0006] The bottom end of the first cone cylinder is connected to the dust hopper. The dust hopper includes an inclined guide plate, a slide rail, and a storage groove. There are two slide rails, which are arranged in parallel at the lower right corner of the dust hopper. The bottom surface of the storage groove is provided with a groove matching the slide rail. The inclined guide plate connects the upper left corner of the dust hopper and the upper left corner of the storage groove, and a vibrator is arranged on the lower side of the inclined guide plate.

[0007] Furthermore, ultrasonic vibrators are arranged on the outer walls of the first cone cylinder and the second cone cylinder for vibrating the first cone cylinder and the second cone cylinder to shake off the dust on the inner walls of the cylinders and fall into the dust hopper below.

[0008] Further, a water absorption filter screen is provided in the pipe section of the intake pipe on the right side of the condensation coil. The fluid entering the air inlet contains dust and water vapor. If the water vapor adheres to the inner walls of the first separation cylinder and the second separation cylinder, the dust on the inner walls will caking and adhere to the inner walls, making it difficult to clean. Removing the water vapor through the water absorption filter screen at the air inlet can prevent this situation from occurring.

[0009] Further, a pull ring is provided on the front side of the storage tank for pulling the storage tank, which facilitates taking out the storage tank and cleaning and replacing the storage tank.

[0010] Further, a bracket is provided on the outer side of the first separation cylinder for supporting the cyclone separator.

[0011] Further, wear-resistant layers are provided on the inner walls of the first separation cylinder and the second separation cylinder to slow down the abrasion of the inner walls by sand or dust and increase the service life of the equipment.

[0012] The present utility model further includes other devices or components that can make the cyclone separator work properly, which are all conventional technical means in the art. In addition, the fans or condensation coils not defined in the present utility model all adopt conventional technical means in the art.

[0013] The working principle of the present utility model is that the incoming dusty fluid of the device first passes through the condensation coil for cooling, so that the water vapor in the fluid condenses into droplets. The droplets are blocked by the water absorption filter screen, and the dry dusty fluid enters the second separation cylinder. Larger sand and dust are removed in the second separation cylinder, and the remaining fluid containing fine dust enters the first separation cylinder through the second cone. The purified fluid obtained after the first separation cylinder removes the fine dust is discharged through the exhaust pipe, and the remaining dust of the cyclone separator is collected into the storage tank.

[0014] The beneficial effects of the present utility model are as follows: the device adopts two-stage cyclone cylinders. The first separation cylinder collects coarser particles, and the second separation cylinder collects fine particles, significantly improving the separation efficiency and reducing the burden on downstream equipment. In addition, it is supplemented with a water absorption filter screen for removing water vapor, a vibrator, and a storage tank for collecting dust, which facilitates cleaning the equipment.
