Specific implementation manners

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0029] Example 1, referring to Figures 1 to 10 , which is the first embodiment of the present invention. This embodiment provides a sintered plate dust collector with a rectifying function, which can achieve the effects of reducing equipment vibration and reducing equipment energy consumption. It includes a box body 100, and a rectangular opening 100a is provided at the bottom of the box body 100. A rectifying mechanism 200 is arranged at the opening 100a in the box body 100; the rectifying mechanism 200 includes guide vanes 201 and air guide pipes 202 symmetrically arranged on both sides of the opening 100a. The guide vanes 201 are arranged in a V shape, and both ends of the guide vanes 201 are fixedly connected to the inner wall of the box body 100 in a sealed manner. The bottom edge of the guide vanes 201 is fixedly connected to the edge of the opening 100a in a sealed manner. Two air guide pipes 202 are located between the guide vanes 201, and the rectangular opening at the bottom of the air guide pipe 202 is smaller than the rectangular opening at the top. The included angle between the side walls between the two air guide pipes 202 is smaller than the included angle between the outer side walls. The included angle between the outer side walls of the two air guide pipes 202 is smaller than the included angle between the two guide vanes 201, and the straight walls at both ends of the air guide pipe 202 are horizontally slidably connected to the inner wall of the box body 100; a frame 203 is provided at the top end of the guide vane 201. A round pipe 203a is connected along the fold line of the frame 203. 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 round pipe 203a.

[0030] Specifically, the bottom edge of the guide vane 201 is bent vertically downward, and the top edge of the guide vane 201 is bent vertically upward. The rectangular opening at the bottom of the air guide pipe 202 is arranged vertically downward, and the rectangular opening at the top of the air guide pipe 202 is arranged vertically upward. The included angle between the side walls between the two air guide pipes 202 is an acute angle, and the included angles between the outer side walls of the two air guide pipes 202 and between the two guide vanes 201 are both obtuse angles.

[0031] The structural principle and advantages of the device are further described in combination with the prior art: In the existing sintered plate dust collector, there is no rectifying structure. Directly feeding the tail gas into the interior of the sintered plate dust collector will cause three problems. First, it will cause equipment vibration. Generally, the sintered plate dust collector has a sturdy steel shell, so the vibration generally will not cause serious losses, but it will obviously increase the production cost in the manufacturing process. Second, it will consume more energy. The generation of eddy currents will cause serious flow resistance, and related fan equipment and pressurization equipment need higher energy consumption to overcome the influence brought by these eddy currents, which will inevitably increase the equipment energy consumption. Third, it will cause local blockage of the sintered plate. Due to the existence of eddy currents, the sintered plate cannot filter evenly everywhere. More tail gas will pass through the places with higher local pressure, causing local blockage, and it is difficult to deal with local blockage by conventional backwashing means.

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

[0033] Since the size of the air intake opening 100a is very limited, the tail gas entering the box 100 from the opening 100a is still relatively concentrated. Therefore, on the basis of the above air intake optimization, a diversion structure is added to make the tail gas smoothly and evenly diffuse at the bottom of the box 100, so that each sintered plate can filter evenly. To achieve this goal, refer to Figure 5 , a total of six metal plates for diversion are designed in this device, including two outermost diversion plates 201 and four side walls of two air ducts 202. These metal plates are all open and inclined to both sides of the opening 100a, and there is a certain distance between them, so that the tail gas is diverted to different directions for diffusion. The technical details are as follows:

[0034] Technical detail one: Since the opening 100a is arranged in the middle of the box 100, the air flow directly hitting in the direction perpendicular to the opening 100a has the advantages of fast flow velocity and low resistance. There is a large space on both sides of the opening 100a. Changing the direction of the air flow and diverting it to both sides will consume part of the air flow energy, and the air flow diffusion will also cause pressure reduction and deceleration. Therefore, more flow needs to be distributed to both sides and less flow is left for the middle. So the distance between the bottoms of the two side walls of the two air ducts 202 close to each other is smaller, 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 bottom of the air duct 202 and the bottom of the diversion plate 201 is even larger, so as to achieve preliminary air flow distribution, so that the incoming air flow after being distributed by the diversion plate 201 and the air duct 202 can rise evenly in the whole box 100, so that each sintered plate filters evenly;

[0035] Technical detail 2: The blades 204 of the rectifying mechanism 200 are opened and closed without relying on the direct blowing of the air flow passing through the blades 204. In the conventional direct blowing method, such as the ordinary louvered air outlet, when the flow rate and velocity are low, the louvers cannot reach the angle parallel to the air flow direction, which will cause air flow refraction and wind resistance. However, the blades 204 of this device can maintain a vertical open state within a wide range of intake air flow rates. Since it does not rely on direct air flow blowing, the blades 204 will instead play a guiding and rectifying role in the passing air flow, further increasing the stability of the air flow flowing in the box body 100. For the control principle of the blades 204, please refer to Embodiment 2.

[0036] In summary, this device can smoothly and evenly diffuse the tail air flow entering the box body 100 at the inner bottom of the sintered plate dust collector, and through the rectification of the guide plate 201, the air duct 202 and the blades 204, the flow rate and direction of the diffused air flow are both stabilized, so that each sintered plate achieves a balanced filtering effect, avoiding or reducing local blockage of the sintered plates and reducing equipment vibration and energy consumption.

[0037] Embodiment 2, referring to Figures 5 to 10 , is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides the control function of the blades 204 of the sintered plate dust collector with rectifying function, which can automatically open the blades 204 when the device is working and automatically close the blades 204 when the device stops working. It includes that at both ends of the two air ducts 202 located on the side close to each other, there are limit plates 205 provided, and the limit plates 205 are symmetric and parallel to each other. There are slide rails 206 provided between the two ends of the air duct 202 and the inner wall of the box body 100, and at both ends of the slide rails 206 on the two air ducts 202 far from each other, there are limit blocks 207 provided, and the limit blocks 207 are fixedly connected to the part of the slide rails 206 on the inner wall of the box body 100 adjacent to them. On one side of the two air ducts 202 close to each other, there are short connecting rods 208 hinged, and the short connecting rods 208 are hinged to each other. The hinge shaft between the short connecting rods 208 is also connected with a pair of pull rods 209, and the two pull rods 209 are V-shaped and penetrate upward to the inside of the round tube 203a. The rotating shaft of the blade 204 penetrates into the round tube 203a, and a long rod 210 is arranged parallel to its axial direction inside the round tube 203a. There is a ball head connecting rod 211 between the long rod 210 and the rotating shaft of the blade 204, and the top end of the pull rod 209 is sleeved on the long rod 210. The end of the ball head connecting rod 211 connected to the rotating shaft of the blade 204 is arranged in an L shape. There is a movable gap between the pull rod 209 and the round tube 203a. The top end of the pull rod 209 can slide axially along the long rod 210, and the rotating shaft of the blade 204 is arranged along the central axis in its length direction. A spring 212 is connected between the two ends of the two short connecting rods 208 far from each other and hinged to each other.

[0038] The deflector 201 of the device is fixed relative to the box body 100, while the air duct 202 can move through the slide rail 206. When the air duct 202 guides the incoming air flow, the air flow will also exert a reaction force on the air duct 202. Refer to Figure 5 , the generated component force will push the two air ducts 202 closer to each other. When the air ducts 202 approach each other, they will squeeze the short connecting rod 208, causing the hinge shaft between the short connecting rods 208 to move downward, thereby driving the pull rod 209 to pull the long rod 210. All the ball joint connecting rods 211 are synchronously pulled through the long rod 210. The deflection of the L-shaped edge of the ball joint connecting rod 211 drives the deflection of the blade 204, so that the blade 204 opens. When the device stops working, the air duct 202 is reset under the elastic force of the spring 212, causing the pull rod 209 to push upward to close the blade 204. Since the air duct 202 has a large flow guiding area, it can easily obtain sufficient thrust in the incoming air flow to complete the control of the blade 204.

[0039] The ideal closed state of the blade 204 is that the blades 204 are coplanar to close the frame 203. The ideal open state of the blade 204 is the 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 rail 206, so that the blade 204 is in the ideal closed state when the guide rail touches the limit block 207. When the air ducts 202 approach each other, when the limit plates 205 between the two air ducts 202 touch each other, the opening angle of the blade 204 reaches the vertical state.

[0040] It should be added that the spring 212 provides the reset elastic force through bending, rather than compression.

[0041] All other structures are the same as those in Embodiment 1.

[0042] In summary, the blade 204 of the device can maintain the vertical open state within a relatively wide incoming air flow range. After opening, it can guide and rectify the air flow passing through, further increasing the stability of the air flow flowing in the box body 100.

[0043] Embodiment 3, refer to Figure 3 and Figure 5, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides the external shape layout of the hopper 102, the frame 203 and the blade 204 of the sintered plate dust collector with a rectifying function, so that the original sintered plate reverse blowing dust removal can still be used normally after using the rectifying mechanism 200. It includes that an air inlet pipe 101 is arranged at the bottom opening 100a of the box body 100. One end of the air inlet pipe 101 extends horizontally to the outside of the box body 100, and the other end of the air inlet pipe 101 is arc-shaped and closed. The upper part of the air inlet pipe 101 is hermetically communicated with the opening 100a. Hoppers 102 are symmetrically arranged on both sides of the air inlet pipe at the bottom of the box body 100. The middle part of the frame 203 is bent into an inverted V shape. A blade 204 is rotatably connected inside the frame 203. The blade 204 is arranged in a rectangular shape, and the blade 204 and its rotation axis are both arranged along the radial direction of the circular tube 203a.

[0044] Reference Figure 5 , when the blade 204 is in the closed state, the top of the inverted V shape formed by the blade 204 and the frame 203 completely covers between the guide plates 201. When the sintered plate performs a reverse blowing operation, the dust falling off the sintered plate slides down along the top of the inverted V shape into the hoppers 102 on both sides of the box body 100. At the same time, means such as an electric vibrator can be used to assist the reverse blowing to collect the dust as much as possible into the hoppers 102. When the device is working, the guide plates 201 of the device can also effectively avoid the secondary pollution of the dust heap in the hopper 102 caused by the incoming air flow.

[0045] All the other structures are the same as those in Embodiment 2.

[0046] In summary, the rectifying mechanism 200 not only has no adverse effect on the reverse blowing cleaning of the original sintered plate dust collector, but also can avoid the secondary pollution of the dust heap in the hopper 102 caused by the incoming air flow.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
