Abstract
Description
A sand separator with adjustable ventilation volume Technical Field
[0001] This invention relates to the field of sand removal equipment technology, specifically to a sand remover with adjustable ventilation. Background Technology
[0002] In the current field of environmental purification technology, inertial sand separators, as an effective air cleaning device, are widely used in various occasions requiring high air quality control. The core working principle of this equipment is to utilize the inertial difference between particulate matter in the airflow and the airflow itself; by using a bend in the channel, particulate matter such as sand and dust is separated due to inertia when the airflow changes direction. However, existing inertial sand separators have certain limitations in their structural design, especially when dealing with air containing high concentrations of sand and dust, where their performance is not ideal.
[0003] Specifically, existing inertial sand separators use fixed bend channels, a design that can maintain a certain level of sand removal efficiency in environments with low dust concentrations. However, in extreme weather conditions such as sandstorms, or in certain industrial environments, the dust concentration in the air can rise sharply. In these situations, the fixed-size bend channels cannot meet the demands for efficient sand removal. Because the size and shape of the channels are not adjustable, high-concentration dust particles can easily overcome existing sand removal mechanisms as they pass through, resulting in some dust remaining in the airflow without being effectively separated.
[0004] This situation not only reduces the overall performance of the air purification system, but the unfiltered dust may also cause wear and tear on other components of the ventilation system, increasing maintenance costs and the risk of equipment failure. Furthermore, the fixed, curved channel design limits the applicability of the inertial sand separator under different environmental conditions, making it unable to adjust to changes in dust concentration, thus affecting its flexibility and effectiveness in practical applications.

Embodiments of the present invention
[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0028] Example 1
[0029] Referring to Figure 1, this embodiment provides a sand remover with adjustable ventilation volume, comprising: a housing 100, with an air inlet and an air outlet at opposite ends; and a sand removal mechanism 200, comprising at least two sand removal components 210 and a sand collection box 230. The at least two sand removal components 210 divide the interior of the housing 100 into a sand collection channel 110 and an exhaust channel 120. The sand collection channel 110 is disposed between the at least two sand removal components 210, with one end connected to the air inlet and the other end extending into the sand collection box 230. The exhaust channel 120 is located between the sand removal components 210 and the inner wall of the housing 100, and is connected to the exhaust outlet. Each sand removal component 210 includes a plurality of corresponding air guides 211 and a plurality of rotating shafts 212. The plurality of rotating shafts 212 are respectively connected to the housing 100. Each of the air guides 211 includes at least two movable blades 2111. The at least two movable blades 2111 are rotatably connected to the corresponding rotating shaft 212. A sand removal channel 213 is formed between two adjacent air guides 211. The sand collection channel 110 and the exhaust channel 120 are connected through the plurality of sand removal channels 213. Sand enters the sand collection box 230 through the sand collection channel 110. The clean gas after sand removal enters the exhaust channel 120 through the sand removal channel 213 and is then discharged. An adjustment mechanism 300 is connected to the at least two sand removal components 210. It drives the at least two movable blades 2111 on the same air guide 211 to open and close relative to each other to adjust the ventilation volume of the sand removal channel 213.
[0030] The adjustable ventilation volume sand separator described in this embodiment achieves flexible adjustment of the ventilation volume through the adjustable sand removal component 210. When the dust content of the gas to be sanded is high, the sand removal effect can be improved by reducing the flow rate of the sand removal channel 213. When the dust content of the gas to be sanded is low, the ventilation volume of the sand removal channel 213 can be increased. Thus, the wind resistance of the sand removal channel 213 is reduced without affecting the sand removal efficiency of the sand removal channel 213. In addition, during extreme sandstorms, the sand separator can completely close the sand removal channel 213 to prevent sand and dust from entering the ventilation system, thereby protecting the internal structure of the sand separator and improving its service life. Compared with the conventional sand removal technology at present, this adjustable ventilation volume sand separator has significant advantages such as flexible use, high controllability, wide applicability, and stable sand removal effect, providing new ideas for the structural design and development of sand removal equipment.
[0031] Referring to Figures 1 and 2, the housing 100 in this embodiment provides a space for sand removal operations and also provides an installation and connection platform for the sand removal mechanism 200 and the adjustment mechanism 300. Its interior is a hollow structure, with an air inlet and an air outlet at both ends of its length that communicate with the outside. In actual operation, the sand-containing gas to be removed enters the housing 100 through the air inlet and comes into contact with the sand removal mechanism 200. The clean gas after sand removal is discharged through the air outlet, and the blocked sand is collected by the sand removal mechanism 200, thereby realizing the sand removal process of the gas.
[0032] In this embodiment, the sand removal mechanism 200 includes two sand removal components 210 spaced apart along the width direction of the housing 100. Both sand removal components 210 extend along the length direction of the housing 100 to increase their contact area with the gas to be sanded, thereby improving the sand removal effect. Furthermore, both ends of any sand removal component 210 in the height direction are connected to the interior of the housing 100, thereby dividing the interior of the housing 100 into a sand collection channel 110. Correspondingly, the space located inside the inner body and outside the sand removal components 210 is the exhaust channel 120. To ensure that the gas carrying sand can stably enter the sand collection channel 110, and that the sand will not be secondary-mixed and contaminated with the clean gas in the exhaust channel 120 due to airflow escape, the sand removal mechanism 200 in this embodiment also includes at least two sealing plates 220. The at least two sealing plates 220 are respectively disposed between the air inlet ends of the at least two sand removal components 210 and the inner wall of the housing 100, so that the gas to be sanded enters the sand collection channel 110.
[0033] Furthermore, in any sand removal component 210, multiple air guides 211 form multiple sand removal channels 213. As the gas carrying sand and dust moves through the sand collection channel 110, the sand and dust are blocked by the multiple air guides 211, thus remaining in the sand collection channel 110. Under the action of directional wind, the sand enters the sand collection box 230, while the clean gas after sand removal enters the exhaust channel 120 through the multiple sand removal channels 213 and finally leaves the housing 100 through the exhaust port, thus completing a complete sand removal process. During this process, the operator can adjust the opening degree of the sand removal channels 213 according to the actual sand removal volume or sand and dust concentration, thereby controlling the overall internal flow of the sand remover. Specifically, the sand removal mechanism 200 also includes a sand discharge fan 240, which is connected to the sand collection box 230, thereby realizing the recovery and removal of sand and dust inside the sand collection box 230, ensuring that this adjustable ventilation sand remover can operate stably for a long time.
[0034] In different embodiments, the adjustable ventilation sand remover may also include a dust concentration sensor connected to the housing 100 and located at the air inlet. The dust concentration sensor is signal-connected to the adjustment mechanism 300, thereby realizing automated detection of the dust concentration in the gas to be removed, thereby further improving the processing efficiency and quality.
[0035] In this embodiment, each sand removal component 210 includes multiple air guides 211 evenly spaced along the length of the housing 100. Each air guide 211 has two movable blades 2111 connected in a "V" shape, which can efficiently stop sand and dust. The rotating shaft 212 is located at the connection point of the two movable blades 2111. Furthermore, in this embodiment, the two movable blades 2111 on each air guide 211 are respectively connected to the adjustment mechanism 300, thereby achieving the effect of relative opening and closing through the synchronous drive of the movable blades 2111 by the adjustment mechanism 300.
[0036] Furthermore, based on the rotatable structure of the movable blade 2111 in this embodiment, during the sand removal process, there may be a gap between the movable blade 2111 and the sand collection box 230, which poses a risk that sand and dust may enter the exhaust channel 120 through the gap. Therefore, the structure of the sand collection box 230 in this embodiment is improved as follows: the sand collection box 230 includes a box body 231, a fixed plate 232, and at least two movable plates 233. The fixed plate 232 is fixed to the inner wall of the housing 100, the box body 231 is connected to the fixed plate 232, and at least two movable plates 233 are respectively disposed on opposite sides of the box body 231. One end of any movable plate 233 abuts against at least one of the movable blades 2111, and the other end is rotatably connected to the fixed plate 232. Furthermore, the sand collection box 230 in this embodiment also includes at least two elastic elements 234, which are respectively connected between the at least two movable plates 233 and the fixed plate 232, so that the movable plates 233 abut against at least one of the movable blades 2111. Preferably, the elastic element 234 is a compression spring, which can apply a stable pushing force to the movable plates 233, thereby ensuring that the movable plates 233 and the movable blades 2111 are always in close contact, fundamentally avoiding the generation of gaps.
[0037] Referring to Figures 3 and 4, in this embodiment, the adjusting mechanism 300 includes a driver 310 and multiple connecting rods 330. The driver 310 is disposed on the housing 100. The multiple connecting rods 330 are respectively connected to the working end of the driver 310 via push rods 320. Each connecting rod 330 is provided with multiple rotating connectors 340, which are respectively connected to multiple movable blades 2111 to drive at least two movable blades 2111 on the same air guide 211 to open and close relative to each other. Specifically, in this embodiment, four connecting rods 330 are provided corresponding to two sand removal components 210. The four connecting rods 330 are arranged in parallel intervals and are correspondingly disposed on both sides of the sand removal component 210 to drive two movable blades 2111 in any sand removal component 210.
[0038] Specifically, in this embodiment, the driver 310 is preferably a linear motor, and the connecting rod 330 is used to transmit the linear driving action of the driver 310 to the rotating connector 340. Then, the rotating connector 340 can convert the linear driving action of the connecting rod 330 into rotational driving, thereby driving the movable blade 2111 to rotate. In this embodiment, the two movable blades 2111 on the same air guide 211 can rotate in opposite directions at the same time, thereby realizing the relative opening and closing process.
[0039] Furthermore, one end of the rotating connector 340 is rotatably connected to the connecting rod 330, and the other end passes through the extension hole 130 via a connecting pin. The movable blade 2111 is rotatably connected to the connecting pin and moves along the extension hole 130 to adjust the ventilation volume of the sand removal channel. The rotating connector 340 is used to change the direction of force, and the extension hole 130 guides the rotation direction of the movable blade 2111. Furthermore, the sand removal assembly 210 also includes multiple sealing elements 214, which cover the intersections of the movable blades 2111 and the rotating connector 340. These sealing elements fill the extension hole 130 during the movement of the movable blades 2111, thereby creating a double sealing effect on the contact gap between the movable blades 2111 and the adjustment mechanism 300.
[0040] Example 2
[0041] Referring to Figures 5 and 6, this embodiment provides another sand remover with adjustable ventilation volume. Its actual operating principle and basic structure are the same as those of Embodiment 1, and will not be described in detail here. In this embodiment, in order to improve the adaptability of the sand remover to different locations, the sand removal mechanism 200 includes multiple sand removal components 210 and multiple adjustment mechanisms 300 to form at least two sand collection channels 110. A sand remover of suitable width can be formed by the cooperation of several sand removal components 210 and several adjustment mechanisms 300. A sealing plate 220 is provided between the air inlet ends of two adjacent sand collection channels 110. The adjustment mechanisms 300 are respectively connected to one of the sand removal components 210 or to two adjacent sand removal components 210.
[0042] Specifically, this embodiment includes four sand removal components 210, which form a serpentine bend structure with their ends connected. The sand removal components 210 located on both sides are connected to the housing 100 through a sealing plate 220 to form two sand collection channels 110. Furthermore, in this embodiment, the two sand collection channels 110 have a larger diameter on the side facing the air inlet. In the direction of sand and dust movement, the sand collection channels 110 gradually narrow, thereby forming a directional transmission effect on sand and dust.
[0043] Among them, the adjustment mechanism 300 at both ends is used to control the sand removal components 210 at both ends, and the other adjustment mechanism 300 is arranged between two adjacent sand removal components 210 in the middle to drive the two sand removal components 210 to rotate synchronously.
[0044] In summary, the adjustable ventilation volume sand separator described in this application achieves flexible adjustment of the ventilation volume of the sand separator through the adjustable sand removal component 210. When the dust content of the gas to be sanded is high, the sand removal effect can be improved by reducing the flow rate of the sand removal channel 213. When the dust content of the gas to be sanded is low, the ventilation volume of the sand removal channel 213 can be increased. Thus, the wind resistance of the sand removal channel 213 is reduced without affecting the sand removal efficiency of the sand removal channel 213. In addition, during extreme sandstorms, the sand separator can completely close the sand removal channel 213 to prevent sand and dust from entering the ventilation system, thereby protecting the internal structure of the sand separator and improving its service life. Compared with the conventional sand removal technology at present, this adjustable ventilation volume sand separator has significant advantages such as flexible use, high controllability, wide applicability, and stable sand removal effect, providing new ideas for the structural design and development of sand removal equipment.
[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
