DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1 to Figure 10 , which is the first embodiment of the present invention, and provides a sintered plate dust collector with a rectifying function, which can achieve the effect of reducing equipment vibration and reducing equipment energy consumption, and comprises a box body 100, and a rectangular opening 100a is opened at the bottom of the box body 100, and a rectifying mechanism 200 is arranged at the opening 100a in the box body 100; the rectifying mechanism 200 comprises a guide plate 201 and an air guide pipe 202 symmetrically arranged on both sides of the opening 100a, the guide plate 201 is arranged in a V-shape, and the two ends of the guide plate 201 are sealed and fixedly connected to the inner wall of the box body 100, and the bottom edge of the guide plate 201 is sealed and fixedly connected to the edge of the opening 100a, and the two sets of air guides are arranged in a V-shaped manner. The tube 202 is located between the guide plates 201, and the rectangular opening 100a at the bottom of the air guide tube 202 is smaller than the rectangular opening 100a at the top, the side wall angle between the two groups of air guide tubes 202 is smaller than the angle between the outer side walls, the angle between the outer side walls of the two groups of air guide tubes 202 is smaller than the angle between the two groups of guide plates 201, and the straight walls at both ends of the air guide tube 202 are horizontally slidably connected to the inner wall of the box 100; a frame 203 is provided at the top of the guide plate 201, and the frame 203 is connected to a circular tube 203a along its fold line, and a blade 204 is rotatably connected inside the frame 203, and the blade 204 and its rotation axis are both arranged along the radial direction of the circular tube 203a.

[0030] Specifically, the bottom edge of the guide plate 201 is bent vertically downward, and the top edge of the guide plate 201 is bent vertically upward, the bottom rectangular opening 100a of the air duct 202 is set vertically downward, and the top rectangular opening 100a of the air duct 202 is set vertically upward, the side wall angle between the two groups of air ducts 202 is an acute angle, and the angle between the outer side walls of the two groups of air ducts 202 and the angle between the two groups of guide plates 201 are both obtuse angles.

[0031] The structural principle and advantages of the device are further explained in combination with the existing technology: the existing sintered plate dust collector does not have a rectification structure, and the exhaust gas directly sent into the sintered plate dust collector will cause three problems. First, it causes equipment vibration. Usually, the sintered plate dust collector has a solid steel casing, so the vibration generally does not cause serious losses, but it will obviously increase the production cost in the manufacturing process. Second, it consumes more energy. The generation of eddy currents will cause serious flow resistance. The related fan equipment and booster equipment require higher energy consumption to overcome the impact of these eddy currents, which will inevitably increase the energy consumption of the equipment. Third, it causes local blockage of the sintered plate. Due to the existence of eddy currents, the sintered plate cannot be filtered evenly everywhere, and more exhaust gas will pass through places with higher local pressure, causing local blockage, and conventional backblowing methods are difficult to deal with local blockages.

[0032] The present invention mainly provides a sintered plate dust collector with an internally integrated rectifying mechanism 200, and optimizes the original side air intake to bottom air intake. Since the exhaust port of a general sintered plate dust collector is arranged at the top, this optimization measure does not require the airflow to change its flow direction drastically, and flows directly from bottom to top, thereby reducing airflow refraction and eddy currents.

[0033] Since the size of the air intake opening 100a is very limited, the exhaust gas entering the box body 100 from the opening 100a is relatively concentrated. Therefore, on the basis of the above air intake optimization, a guide structure is added to make the exhaust gas diffuse smoothly and evenly at the bottom of the box body 100, so that each sintering plate can be filtered evenly. To achieve this goal, refer to Figure 5 The device is designed with a total of six metal plates for guiding, including the two outermost guide plates 201 and the four side walls of the two air guide pipes 202. These metal plates are open and inclined to both sides of the opening 100a, and there is a certain distance between them, so that the exhaust gas is guided to different directions for diffusion. The technical details are as follows: Technical detail 1: The opening 100a is set in the middle of the box 100. The airflow rushing straight in the direction perpendicular to the opening 100a has the advantages of fast flow rate and low resistance. There is a large space on both sides of the opening 100a. Changing the direction of the airflow to the two sides will consume part of the airflow energy, and the airflow diffusion will also cause pressure reduction and deceleration. Therefore, it is necessary to distribute more flow to the two sides and leave less flow to the middle. Therefore, the distance between the bottoms of the two side walls of the two air ducts 202 close to each other is small, and the distance between the bottoms of the two side walls of a single air duct 202 is relatively increased, and the distance between the air duct 202 and the bottom of the guide plate 201 will be larger, thereby realizing preliminary airflow distribution, so that the inlet airflow distributed by the guide plate 201 and the air duct 202 can rise evenly in the entire box 100, so that each sintering plate is evenly filtered; Technical detail 2: The opening and closing of the blades 204 of the rectifying mechanism 200 do not rely on the direct blowing of the airflow passing through the blades 204. Conventional direct blowing methods, such as ordinary louvered exhaust vents, cannot achieve an angle parallel to the airflow direction when the flow rate and flow velocity are low, which will cause airflow refraction and wind resistance. The blades 204 of the device can maintain a vertical open state within a wider range of intake flow. Since it does not rely on direct blowing of the airflow, the blades 204 will guide and rectify the airflow passing through after opening, further increasing the stability of the airflow flowing in the box 100. For the control principle of the blades 204, please refer to Example 2.

[0034] In summary, the device can smoothly and evenly diffuse the exhaust gas flow entering the box 100 at the bottom of the sintered plate dust collector, and rectify it through the guide plate 201, the air duct 202 and the blade 204, so that the flow rate and direction of the diffused air flow are stabilized, so that each sintered plate can achieve a balanced filtering effect, avoid or reduce local blockage of the sintered plate and reduce equipment vibration and energy consumption.

[0035] Example 2, reference Figure 5~Figure 10 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a blade 204 control function of a sintered plate dust collector with a rectifying function, which can automatically open the blade 204 when the equipment is working, and automatically close the blade 204 when the equipment stops working. It includes: both ends of the two groups of air ducts 202 are located on the side close to each other, and the limiting plates 205 are symmetrical and parallel to each other. Slide rails 206 are arranged between the two ends of the air ducts 202 and the inner wall of the box 100, and both ends of the slide rails 206 on the two groups of air ducts 202 that are far away from each other are provided with limiting blocks 207, and the limiting blocks 207 are fixedly connected to the adjacent slide rails 206 located on the inner wall of the box 100, and the two groups of air ducts 202 are hinged with short connecting rods 208 on the side close to each other, and the short connecting rods 20 8 is hinged, and the hinge axis between the short connecting rods 208 is also connected to a pair of pull rods 209, and the two pull rods 209 are V-shaped and extend upward to the inside of the circular tube 203a, the rotating shaft of the blade 204 extends into the circular tube 203a, and a long rod 210 is arranged in the circular tube 203a parallel to its axial direction, a ball head connecting rod 211 is arranged between the long rod 210 and the rotating shaft of the blade 204, and the top end of the pull rod 209 is sleeved with the long rod 210, and the end of the ball head connecting rod 211 connected to the rotating shaft of the blade 204 is L-shaped, and a movable gap is left between the pull rod 209 and the circular tube 203a, and the top end of the pull rod 209 can slide with the long rod 210 along the axial direction of the long rod 210, and the rotating shaft of the blade 204 is arranged along the central axis in its length direction, and a spring 212 is connected between the two ends of the two short connecting rods 208 hinged to each other that are away from each other.

[0036] The guide plate 201 of the device is fixed relative to the box body 100, while the air guide 202 can move through the slide rail 206. When the air guide 202 does not provide guidance for the incoming air flow, the air flow will also exert a reaction force on the air guide 202. Figure 5 The component force generated will push the two air ducts 202 closer to each other. The air ducts 202 approaching each other will squeeze the short connecting rod 208, causing the hinge axis between the short connecting rods 208 to move downward, thereby driving the pull rod 209 to pull the long rod 210, and all the ball head connecting rods 211 are pulled synchronously through the long rod 210, and the deflection of the L-shaped edge of the ball head connecting rod 211 drives the deflection of the blade 204, so that the blade 204 is opened. When the equipment stops working, the air duct 202 is reset under the elastic force of the spring 212, so that the pull rod 209 pushes up to close the blade 204. Since the air duct 202 has a large flow guiding area, it can easily obtain sufficient thrust in the intake airflow to complete the control of the blade 204.

[0037] The ideal closed state of the blades 204 is that the blades 204 are coplanar and close the frame 203. The ideal open state of the blades 204 is a vertical state. Therefore, it is necessary to control the movement stroke of the air duct 202. When the air ducts 202 move away from each other, they are restricted by the limit blocks 207 on the slide rails 206 so that when the guide rails contact the limit blocks 207, the blades 204 are in the ideal closed state. When the air ducts 202 approach each other, when the limit plates 205 between the two air ducts 202 contact each other, the blades 204 open at an angle to a vertical state.

[0038] It should be additionally explained that the spring 212 provides the restoring elastic force by bending, rather than by compression.

[0039] The rest of the structure is the same as that of Example 1.

[0040] In summary, the blades 204 of the device can maintain a vertically open state within a wider range of air intake flow, and after opening, they can guide and rectify the airflow passing through, further increasing the stability of the airflow flowing in the box 100.

[0041] Example 3, reference Figure 3 and Figure 5, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an outer layout of an ash hopper 102, a frame 203 and blades 204 of a sintered plate dust collector with a rectifying function, so that the original sintered plate back-blowing dust collector can still be used normally after using the rectifying mechanism 200. It includes: an air inlet duct 101 is arranged at the bottom opening 100a of the box body 100, one end of the air inlet duct 101 extends horizontally to the outside of the box body 100, and the other end of the air inlet duct 101 is closed in an arc shape, the upper part of the air inlet duct 101 is sealed and connected to the opening 100a, and the bottom of the box body 100 is symmetrically provided with ash hoppers 102 on both sides of the air inlet duct, the middle part of the frame 203 is bent into an inverted V shape, and blades 204 are rotatably connected in the frame 203. The blades 204 are arranged in a rectangular shape, and the blades 204 and their rotation axes are arranged along the radial direction of the circular tube 203a.

[0042] refer to Figure 5 When the blade 204 is in a closed state, the inverted V-shaped top formed by the blade 204 and the frame 203 completely covers the space between the guide plates 201. When the sintering plate is backblown, the dust falling off the sintering plate slides along the inverted V-shaped top into the ash hopper 102 on both sides of the box body 100. At the same time, the backblowing can be assisted by means of an electric vibrator so that the dust can be collected into the ash hopper 102 as much as possible. When the device is working, the guide plate 201 of the device can also effectively avoid secondary pollution of dust in the ash pile in the ash hopper 102 caused by the intake airflow.

[0043] The rest of the structure is the same as that of Example 2.

[0044] In summary, the rectifying mechanism 200 not only has no adverse effect on the back-flushing cleaning of the original sintering plate dust collector, but also can avoid the secondary pollution of dust in the ash pile in the ash hopper 102 caused by the incoming airflow.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
