Description

Technical Field

[0001] The invention relates to the field of dust removal equipment, in particular to a sintered plate dust collector with a purge function. Background Art

[0002] After working for a period of time, the sintered plate dust collector needs to be cleaned by backblowing. However, the sintered plate often has a large filtration area, and the blockage conditions in different places are also different. Often the first backblowing can clean up most of the dust, but the effect of backblowing again for residual local blockages becomes poor. This is because the first backblowing makes most of the sintered plate unblocked, resulting in the backblowing pressure being quickly released through the unblocked part when backblowing again. Therefore, it is difficult to generate a higher pressure difference to have a cleaning effect on the local blockage. Therefore, in order to solve the above problem, a sintered plate dust collector with a purge function that can perform local high-pressure purge and dust removal is proposed.

DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1, reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, provides a sintering plate 101 dust collector with a purge function, which can achieve the effect of local high-pressure purge at any position of the sintering plate 101, and includes a box body 100 and a sintering plate 101 in the box body 100, the side wall cross-section of the sintering plate 101 is wavy, and the top of the sintering plate 101 is sealed with a shell 102, and a purge mechanism 200 is arranged between the shell 102 and the sintering plate 101; the purge mechanism 200 includes a round cover 201 arranged at both ends of the shell 102, and a toothed ring 202 is arranged on one side of the round cover 201 located in the shell 102, and the toothed ring 202 is meshed with a gear 2 03, the two round covers 201 are respectively connected with a motor 204 and an air connector 205, a pair of coaxially connected reciprocating screws 206 are arranged between the two gears 203, and each reciprocating screw 206 is matched and connected with a slider 207, an H-shaped air pipe 208 is connected between the two sliders 207, and one end of the horizontal pipe of the H-shaped air pipe 208 is closed, and the other end of the H-shaped air pipe 208 is sealed and connected with a hose 209, and the other end of the hose 209 is connected to the air connector 205, and the two vertical pipes of the H-shaped air pipe 208 are slidably sleeved with a sleeve 210, the bottom end of the sleeve 210 is closed, and the top circumferential wall and the bottom circumferential wall of the sleeve 210 are both provided with nozzles 210a.

[0032] Specifically, the reciprocating screw 206 is fixedly connected to the gear 203, and the reciprocating screw 206 is located at one end of the motor 204 and is rotatably sleeved with an L-shaped adapter 212, one end of the adapter 212 is perpendicular to the reciprocating screw 206, and the other end of the adapter 212 is coaxially connected to the output shaft of the motor 204, the distance between the two sleeves 210 is close to half the width of the sintering plate 101, and the stroke length of a single reciprocating screw 206 is close to half the width of the sintering plate 101, the distance between the nozzles 210a at both ends of the sleeve 210 is close to half the height of the sintering plate 101, and the sleeve 21 0 and the maximum overlapping length of the H-shaped air pipe 208 is greater than half of the height of the sintered plate 101, the reciprocating screw 206 and the cross tube of the H-shaped air pipe 208 and the output shaft of the motor 204 are parallel to each other, an air outlet 102a is opened at the top of the shell 102, and the air outlets 102a are evenly spaced about the shell 102, and the air outlets 102a are all sleeved with sealing rings 102b, a partition 103 is horizontally arranged on the top of the box body 100, and the shell 102 is fixedly connected to the partition 103, the partition 103 is opened at the air outlet 102a, and the sealing ring 102b is crimped with the partition 103.

[0033] In combination with the prior art, the technical principles and advantages of the device are further explained: In the prior art, the sintering plate 101 can be cleaned and reused repeatedly, but the sintering plate 101 is installed inside the equipment and is very inconvenient to disassemble and assemble. Generally, it is only disassembled and cleaned when backflushing cannot effectively clean the sintering plate 101 and the sintering plate 101 is blocked and it is difficult to maintain the production flow. Backflushing cleaning refers to the release of a large flow of compressed air inward from the exhaust port of the sintering plate 101 to blow away the dust attached to the outer wall of the sintering plate 101. Obviously, the effect of backflushing is greatly limited, and it is difficult to achieve an effective cleaning effect for severe local blockages.

[0034] The present invention mainly provides a purging mechanism 200 which can circulate inside a commonly used wavy sintering plate 101 to blow and remove dust from a part of the sintering plate 101. One of the core parts of the mechanism is an H-shaped air pipe 208 (the H-shaped air pipe 208 is made of hard metal pipes welded and assembled. For the convenience of description, the two longer parts of the H-shaped air pipe 208 are described as vertical pipes, and the middle horizontal part is described as horizontal pipe). The purging mechanism 200 has a total of four groups of purging nozzles 210a, which are respectively arranged at the top and bottom ends of two sleeves 210. The sintering plate 101 is locally dusted through the four nozzles 210a. To achieve the circulation and covering purging of the inside of the sintering plate 101 by the four nozzles 210a, it is not only necessary for the sleeve 210 to achieve up and down movement, but also to be able to move along the wavy path inside the sintering plate 101.

[0035] The up and down movement of the sleeve 210: the sleeve 210 is sleeved with the vertical pipe part of the H-shaped air pipe 208, and the inside is connected by a tension spring 211. The compressed gas reaches the sleeve 210 through the H-shaped air pipe 208 and is ejected from the nozzle 210a. At the same time, since the pressure between the sleeve 210 and the H-shaped air pipe 208 is greater than the pressure inside the sintering plate 101, the sleeve 210 overcomes the tension of the tension spring 211 and moves downward. During the process, the nozzle 210a at the top of the sleeve 210 purges the upper half of the sintering plate 101, and the nozzle 210a at the bottom of the sleeve 210 purges the lower half of the sintering plate 101.

[0036] Horizontal movement of the sleeve 210 wave path: To pass through the wave path, the sleeve 210 needs to continuously make left and right reciprocating movements. Figure 6 The motor 204 of the device drives the reciprocating screw 206 to make a circular motion through an L-shaped connecting piece. The slider 207 is slidably connected to the reciprocating screw 206, and the H-shaped air pipe 208 connected to the slider 207 acts downward due to gravity, so that the H-shaped air pipe 208 and the sleeve 210 maintain a downward posture and move back and forth left and right with the revolution of the reciprocating screw 206 around the motor 204 axis. Every time the motor 204 axis rotates one circle, the sleeve 210 is separated to the two sides of the sintering plate 101. At the same time, the gear 203 at the end of the reciprocating screw 206 will roll in the gear ring 202, thereby driving the reciprocating screw 206 to rotate. The rotating reciprocating screw 206 will also drive the slider 207 to move along its axial direction. Through the superposition of the left and right (relative to the two sides of the sintering plate 101) displacement of the sleeve 210 and the axial displacement along the axis of the motor 204, the H-shaped air pipe 208 and the sleeve 210 can move smoothly inside the sintering plate 101 along a wave path.

[0037] The wave-like movement of the sleeve 210 only depends on whether the motor 204 is rotating. The rotation of the motor 204 causes the sleeve 210 to move left and right relative to the sintering plate 101, and also causes the sleeve 210 to move up and down slightly. When the motor 204 stops, the sleeve 210 can also move up and down independently and be purged by compressed gas. The source of the compressed gas for purging is provided by the hose 209 and the joint connected to the H-shaped air pipe 208.

[0038] In summary, the sleeve 210 of the device can be used for up and down blowing alone, or it can be used for reciprocating blowing along the wavy interior of the sintering plate 101 alone, or it can be combined with the two to fully cover the interior of the sintering plate 101 and blow the local high-pressure air through the nozzle 210a, which can solve the problem of local blockage that cannot be cleaned by traditional overall backblowing, and has a simple structure and low cost.

[0039] Example 2, reference Figure 4 to Figure 12, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a pipeline layout of a sintering plate 101 dust collector with a purge function, so that the purge range of the purge mechanism 200 can cover the entire sintering plate 101, which includes: the inner diameter of the sleeve 210 is larger than the outer diameter of the H-shaped air pipe 208 vertical pipe, and the top opening of the sleeve 210 is narrowed and slidably connected with the H-shaped air pipe 208 vertical pipe, and the nozzle 210a is flat, and the nozzles 210a are distributed in a ring array with respect to the sleeve 210, and a circular ring 210b is arranged along the axial direction of the bottom end of the sleeve 210, and the outer diameter of the circular ring 210b is equal to the outer diameter of the H-shaped air pipe 208 vertical pipe, and a tension spring 211 is sleeved between the circular ring 210b and the H-shaped air pipe 208 vertical pipe, and the top end of the tension spring 211 is connected to the top end of the H-shaped air pipe 208 vertical pipe, and the bottom end of the tension spring 211 is connected to the bottom end of the sleeve 210.

[0040] refer to Fig.11 and Fig.12 , the flow cross-sections of the compressed gas reaching the nozzles 210a at both ends of the sleeve 210 are not the same, especially when the sleeve 210 and the H-shaped air pipe 208 are relatively overlapped, the compressed gas needs to pass through the gap between the inner wall of the sleeve 210 and the outer wall of the vertical pipe of the H-shaped air pipe 208 to reach the nozzle 210a at the top of the sleeve 210, so the flow area will be relatively small, affecting the jet pressure balance of the nozzles 210a at both ends of the sleeve 210. Therefore, a ring 210b with the same inner and outer diameters as the H-shaped vertical pipe is provided at the bottom of the sleeve 210 to reduce the flow area of ​​the compressed gas reaching the nozzle 210a at the bottom of the sleeve 210, so as to balance the purge effects of the two nozzles 210a.

[0041] The rest of the structure is the same as that of Example 1.

[0042] In summary, the two groups of nozzles 210a of the sleeve 210 of the device can make the purge effects of the two groups of nozzles 210a as close as possible by adjusting the internal flow cross-sectional area.

[0043] Example 3, reference Figure 4 , Figure 5 and Fig. 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a roller 213 of the dust collector of the sintering plate 101 with a purging function, so that the sleeve 210 maintains a nearly vertical posture in the sintering plate 101, which includes: the peripheral wall of the sleeve 210 is rotatably sleeved with the roller 213, and the diameter of the roller 213 is smaller than the gap width inside the sintering plate 101.

[0044] The premise for the reciprocating screw 206 to rotate and drive the sleeve 210 to move along its axial direction is that, with the slider 207 as a reference, the slider 207 does not rotate, and the reciprocating screw 206 can rotate to effectively drive the slider 207 to move along the axial direction through the spiral groove on the reciprocating screw 206. The device is mainly achieved through the downward gravity of the metal air pipe and the sleeve 210, but this is still not stable enough. The sleeve 210 will swing due to the friction between the slider 207 and the reciprocating screw 206, and the instability caused by the purge airflow of the nozzle 210a will further aggravate the swing of the sleeve 210. Therefore, it is necessary to add a roller 213 to the sleeve 210.

[0045] Firstly, the swing of the sleeve 210 is limited by the reciprocating screw 206, and can only be performed on both sides of the sintering plate 101 with the reciprocating screw 206 as the axial direction. Secondly, the diameter of the roller 213 should be slightly smaller than the gap width inside the sintering plate 101 to avoid the roller 213 being stuck inside the sintering plate 101. The gap allows and only allows the sleeve 210 to have a small swing that does not affect its normal operation, and only one side of the roller 213 will contact the inner wall of the sintering plate 101, so that the roller 213 can roll smoothly along the inner wall of the sintering plate 101.

[0046] The rest of the structure is the same as that of Example 2.

[0047] In summary, the movement of the device is greatly improved in stability through the design of the roller 213 .

[0048] 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.
