Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a reflective cyclone dust collector with a flat reflector for plastic powder recycling. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the collector, and its dust removal efficiency. At the same time, the price, operating and maintenance costs, service life, and ease of operation and management are also important factors to consider when evaluating its performance.

[0003] Existing cyclone dust collectors are generally equipped with filter elements for enhanced filtration, but they can only have a single inlet for air intake during dust removal, which cannot handle large volumes of dust and flue gas. Therefore, a reflective cyclone dust collector with a flat reflector plate for plastic powder recovery is proposed. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A reflective cyclone dust collector with a flat reflector for plastic powder recycling includes an air inlet mechanism, a cyclone separator mechanism, and a hydrocyclone system. The air inlet mechanism includes an air inlet volute, multiple air inlets located on the side of the air inlet volute, a lower interface connected to the lower inner side of the air inlet volute, an upper interface connected to the upper inner side, and a guide duct for guiding the airflow direction. The cyclone separator mechanism includes a straight cylinder connected to the lower part of the air inlet volute, a circular reflector installed inside the straight cylinder, a cyclone diffusion settling chamber connected to the bottom of the straight cylinder, and a dust pump for discharging dust. The cyclone separator mechanism includes a cyclone inner cylinder connected to the upper part of the air inlet volute, a gas buffer chamber located on the upper outer side of the cyclone inner cylinder, a flared opening installed between the gas buffer chamber and the cyclone inner cylinder, an air inlet connected to the bottom side of the gas buffer chamber, and an air outlet located at the top of the cyclone inner cylinder.

[0007] In a preferred embodiment, the present invention can be further configured such that the multi-point air inlet includes one to N air inlets, and the multi-point air inlets are evenly arranged on the side of the lower interface.

[0008] By adopting the above technical solution, multiple entry points for air intake are possible, thereby increasing the intake air volume, and each air intake is guided by a guide air duct.

[0009] In a preferred embodiment, the present invention can be further configured such that: a right-angled trapezoidal cylindrical support is provided on the outer side of the straight cylindrical body, and a reflector support is provided below the circular reflector.

[0010] By adopting the above technical solution, the position of the circular reflector is fixed by the reflector support, which effectively improves the stability of the structure.

[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom of the gas buffer chamber is equipped with a lower cover and the top of the gas buffer chamber is provided with an upper cover, the lower cover and the upper cover together with the outer wall of the buffer chamber to form a sealed gas buffer chamber.

[0012] By adopting the above technical solution, the gas buffer chamber is kept in a sealed state, so that the gas will not be leaked during swirling, which would weaken the rotation force and affect the separation effect.

[0013] In a preferred embodiment, the present invention can be further configured such that the side of the bottom end of the inner cylinder of the cyclone separator is connected to the upper interface, and the air intake is spiral.

[0014] By adopting the above technical solution, the air intake will not be straight up and down, and the spiral air intake effectively improves the separation effect.

[0015] In a preferred embodiment, the present invention can be further configured such that the exhaust direction of the horn is opposite to the air intake direction of the air inlet.

[0016] By adopting the above technical solution, the air pressure in the buffer chamber is improved and stabilized, effectively ensuring the stability of the flow rate of the gas discharged from each flare.

[0017] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0018] 1. In this utility model, by setting multiple air inlets on the air inlet volute, the air intake volume can be increased, enabling the device to handle a larger volume of dust-laden gas and improving the device's practicality. At the same time, in order to handle this volume of dust-laden gas, a flared opening is set between the inner cylinder of the cyclone separator and the gas buffer chamber, so that the gas is strengthened by the flared opening and falls into the straight cylinder, forming a stronger cyclone, thereby enhancing the intensity of dust separation and effectively improving the dust removal effect of the device.

[0019] 2. In this utility model, by setting a circular reflector inside the straight cylinder, the dust-laden cyclone will be reflected after hitting the circular reflector, and the clean gas will be reflected to the outlet for discharge. The dust will be decelerated by centrifugal force and reflected to the inner wall of the straight cylinder, and then enter the cyclone diffusion settling chamber and be discharged by the dust pump, which effectively ensures the reliability of dust separation.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a reflective cyclone dust collector with a flat reflector for plastic powder recycling.

[0030] Example 1:

[0031] Combination Figure 1-3As shown, this utility model provides a reflective cyclone dust collector with a flat reflector for plastic powder recycling, including an air intake mechanism 100, a cyclone separator mechanism 200, and a cyclone separator mechanism 300. The air intake mechanism 100 includes an air intake volute 110, multiple air inlets 120 disposed on the side of the air intake volute 110, a lower interface 130 connected to the lower inner side of the air intake volute 110, an upper interface 140 connected to the upper inner side, and a guide air duct 150 for guiding the airflow direction. The cyclone separator mechanism 200 includes a straight cylinder 210 connected to the lower part of the air intake volute 110, a circular reflector 230 assembled inside the straight cylinder 210, a cyclone diffusion settling chamber 250 connected to the bottom of the straight cylinder 210, and a dust pump 260 for discharging dust. The cyclone separator mechanism 300 includes a cyclone inner cylinder 310 connected to the upper part of the air intake volute 110, and a gas buffer disposed on the outer side above the cyclone inner cylinder 310. The system includes a flushing chamber 320, a flared opening 360 between the gas buffer chamber 320 and the inner cylinder 310 of the cyclone separator, an air inlet 350 connected to the bottom side of the gas buffer chamber 320, and an air outlet 380 located at the top of the inner cylinder 310. The exhaust direction of the flared opening 360 is opposite to the air intake direction of the air inlet 350. Air is intaked through the air intake mechanism 100 and guided into the cyclone separator mechanism 200. A cyclone is formed in the cyclone separator mechanism 200, generating centrifugal force, which throws the dust out and causes it to collide with the inner wall of the straight cylinder 210, slowing it down. Finally, the dust falls into the cyclone diffusion settling chamber 250 and is discharged by the dust pump 260, thus achieving dust separation. At the same time, the flared opening 360 between the gas buffer chamber 320 and the inner cylinder 310 of the cyclone separator allows the gas to swirl, thereby enhancing the strength of the cyclone inside the straight cylinder 210 and increasing the centrifugal force of the cyclone, effectively ensuring the dust separation effect.

[0032] Example 2:

[0033] Combination Figure 1 , Figure 3 As shown, based on Embodiment 1, the multi-point air inlet 120 includes multiple air inlets from air inlet 121 to air inlet N122, and the multi-point air inlets 120 are evenly arranged on the side of the lower interface 130. The multiple multi-point air inlets 120 are arranged on the side of the air guide duct 150 to make the air intake uniform, so that the device can process more dust-laden gas at the same time, effectively improving the working efficiency of the device.

[0034] Specifically, a right-angled trapezoidal cylindrical support 220 is provided on the outer side of the straight cylindrical body 210, and a reflector support 240 is provided below the circular reflector 230. The reflector support 240 is used to support and fix the position of the circular reflector 230, so that the cyclone column can be quickly reflected after colliding with the circular reflector 230, thus ensuring the dust removal effect of the device.

[0035] Example 3:

[0036] Combination Figure 1 As shown, in the above embodiment, the bottom of the gas buffer chamber 320 is equipped with a lower cover 340, and the top of the gas buffer chamber 320 is provided with an upper cover 370. The lower cover 340 and the upper cover 370, together with the outer wall 330 of the buffer chamber, form a sealed gas buffer chamber 320. The gas obstruction at the horn opening 360 is guided by the outer wall 330 of the buffer chamber, so that the gas discharged from the horn opening 360 enters the straight cylinder 210 in a spiral shape, thereby enhancing the centrifugal force of the cyclone inside the straight cylinder 210 and improving the separation effect.

[0037] Specifically, the side of the bottom end of the hydrocyclone inner cylinder 310 is connected to the upper interface 140, and the air enters in a spiral. By setting the opening at the bottom end of the hydrocyclone inner cylinder 310 on the side, the gas entering from the upper interface 140 will move in a spiral shape inside the hydrocyclone inner cylinder 310, effectively improving the separation effect of the device.

[0038] The working principle and usage process of this utility model are as follows: First, the dust-laden airflow is captured by the air intake mechanism 100, and the dust-laden gas is guided to the cyclone mechanism 200 for separation through the air guide duct 150. The separated clean gas rises into the gas buffer chamber 320, and then enters the straight cylinder 210 through the horn mouth 360 to increase the rotation speed, thereby increasing the centrifugal force of the dust. When it reaches the circular reflector plate 230, the clean gas inside the swirling gas column rises rapidly and is discharged through the air outlet 380. When the dust on the outside comes into contact with the inner wall of the straight cylinder 210, it decelerates and settles into the swirling diffusion settling chamber 250. Finally, it is extracted by the powder pump 260.
