Description

Technical Field

[0001] The invention belongs to the field of garbage processing equipment, in particular to a grate group staggered support system for alternating transverse concave and convex forward and reverse thrusts. Background Art

[0002] The main methods of urban domestic waste treatment are landfill, biocomposting and incineration. The environmental industry report points out that the general trend of waste treatment development is: recycling based on classified collection is increasingly valued and the proportion is gradually increasing, the standards for landfill will become higher and higher, the proportion of landfill will gradually decrease, and waste incineration will develop steadily, and the proportion of incineration waste heat power generation will increase.

[0003] In the domestic waste incineration system, the incineration grate is the most critical equipment. The technology of the incineration grate affects whether the waste can be completely burned, the content of unburned organic matter in the ash discharged from the furnace body, and the heat recovery efficiency from the waste. In order to make the waste in the waste incinerator fully and completely burn, and reduce the thermal loss of the ash, it is required to fully contact the waste with the combustion air as much as possible to achieve the purpose of complete combustion, while at the same time not increasing the volume of the furnace body as much as possible.

[0004] At present, the garbage incineration grates are mainly of horizontal reverse push type or horizontal forward push type. The grates on the entire grate bed are built one by one and move in the same direction when in motion, which often results in incomplete combustion of garbage. The ash discharged from the furnace body contains a high content of unburned organic matter, which reduces the heat recovery efficiency from the garbage, affects sanitary landfill, and pollutes the environment.

[0005] We have now designed a single-row grate group with alternating forward and reverse push arrangements, which can solve the technical problem of side wall effect on both sides of the grate. Since the forward push grates and reverse push grates need to run crosswise, the support system is another difficult problem. How to design a support system on an integral grate to pull several rows of grate groups to move at the same time is the main problem to be solved in this design. Summary of the invention

[0006] The present invention aims to provide a staggered support system for a grate group with alternating forward and reverse thrust in transverse direction, so as to solve the technical problem that a common support system is required for multiple forward and reverse thrust grate groups in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides a staggered support system for a grate group with transverse concave-convex and forward-reverse alternations, wherein the grate group with transverse concave-convex and forward-reverse alternations comprises at least two groups of forward-pushing grate groups and one group of reverse-pushing grate groups, wherein the reverse-pushing grate group is in the middle and the two groups of forward-pushing grate groups are on both sides, and the width of the reverse-pushing grate group is greater than the width of the forward-pushing grate group;

[0008] The grate group dislocation support system includes a reverse push beam carrying the reverse push grate group, a forward push beam carrying the forward push grate group, a reverse push rod beam carrying the reverse push beam, a forward push rod beam carrying the forward push beam, and a symmetrically designed left rod beam bracket and a right rod beam bracket.

[0009] The left tie rod beam support and the right tie rod beam support are in the shape of stairs, and the top slope surface thereof is divided into two layers, the upper layer is the upper slope beam, and the lower layer is the lower slope beam. The upper slope beam and the lower slope beam are parallel to each other, and an upper roller is vertically installed on the inner side of the upper slope beam, and a lower roller is vertically installed on the inner side of the lower slope beam, and the upper and lower rollers are staggered.

[0010] The reverse push rod beam and the forward push rod beam are in a rectangular frame structure. The left and right sides of the reverse push rod beam are built on the lower roller, and the reverse push beams are built in a horizontal row along the length direction of the reverse push rod beam. The left and right sides of the forward push rod beam are built on the upper roller, and the forward push beams are built in a horizontal row along the length direction of the forward push rod beam. The reverse push beams and the forward push beams are arranged in a cross-spaced manner.

[0011] Furthermore, the upper slope beam, the lower slope beam, the forward push rod beam, and the reverse push rod beam remain parallel to each other, and the inclination angle thereof is 25°.

[0012] Furthermore, the reverse thrust beam includes more than one convex beam, which is arranged at equal intervals along the inclined reverse thrust tie rod beam. The top of the convex beam is connected to the bottom of the reverse thrust grate group, and the left and right ends of the convex beam are mounted on the left and right sides of the reverse thrust tie rod beam.

[0013] Furthermore, the push-forward beam includes more than one concave beam, which is arranged at equal intervals along the inclined push-forward pull rod beam. The left and right ends of the concave beam are mounted on the left and right sides of the push-forward pull rod beam, and the middle recessed part of the concave beam is lower than the middle protruding part of the convex beam.

[0014] Furthermore, the left and right sides of the upper slope beam, the lower slope beam, the forward push rod beam and the reverse push rod beam are all in a staircase structure, divided into an inclined part and a horizontal part, wherein the left and right ends of the convex beam and the concave beam are mounted on the horizontal part.

[0015] Furthermore, movable wheels are fixed to the bottom of the left tie rod beam bracket and the right tie rod beam bracket.

[0016] Furthermore, a hinged component for installing a reverse push grate group is provided on the top surface of the middle protruding part of the convex beam, and a hinged component for installing a forward push grate group is provided on the top surfaces of the left and right ends of the concave beam.

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0028] like Figure 4 , Figure 5 As shown, the grate group with alternating horizontal concave and convex forward and reverse pushes includes at least two groups of forward push grate groups 2 and one group of reverse push grate group 3, the reverse push grate group 3 is in the middle, and the two groups of forward push grate groups 2 are on both sides, and the width of the reverse push grate group 3 is greater than the width of the forward push grate group 2; an isolation wall 4 is also provided between the reverse push grate group 3 and the two groups of forward push grate groups 2, and the forward push grate groups 2 and the reverse push grate 3 are arranged in a stepped manner along the length direction of the isolation wall 4, that is, the forward push grate groups 2 and the reverse push grate 3 are built up like a staircase structure.

[0029] like Figure 1-Figure 6 The staggered support system for the grate group with alternating horizontal concave and convex forward and reverse thrusts comprises a reverse thrust beam for carrying the reverse thrust grate group, a forward thrust beam for carrying the forward thrust grate group, a reverse thrust tie rod beam 9 for carrying the reverse thrust beam, a forward thrust tie rod beam 10 for carrying the forward thrust beam, and a symmetrically designed left tie rod beam bracket 5 and a right tie rod beam bracket 6.

[0030] The left tie rod beam support 5 and the right tie rod beam support 6 are in the shape of stairs, and the top slope surface thereof is divided into two layers, the upper layer is an upper slope beam 61, and the lower layer is a lower slope beam 62. The upper slope beam 61 and the lower slope beam 62 are parallel to each other, an upper roller 63 is vertically installed on the inner side of the upper slope beam 61, and a lower roller 64 is vertically installed on the inner side of the lower slope beam 62. The upper and lower rollers are staggered.

[0031] The reverse push rod beam 9 and the forward push rod beam 10 are in a rectangular frame structure. The left and right sides of the reverse push rod beam 9 are built on the lower roller 64, and the reverse push beams are built in sequence in a horizontal row along the length direction of the reverse push rod beam 9. The left and right sides of the forward push rod beam 10 are built on the upper roller 63, and the forward push beams are built in sequence in a horizontal row along the length direction of the forward push rod beam 10. The reverse push beams and the forward push beams are arranged in a cross-spaced manner.

[0032] The upper slope beam, lower slope beam, forward push rod beam and reverse push rod beam are parallel to each other, and the inclination angle is 25°. When we add a power mechanism to the top of the reverse push rod beam and the forward push rod beam, the left pull rod beam bracket 5 and the right pull rod beam bracket 6 and the isolation wall 4 are inactive, then the reverse push rod beam 9 and the forward push rod beam 10 respectively fixed on the upper and lower rollers 64 will swing, and pull the two forward push grate groups 2 and one reverse push grate group 3 to move.

[0033] Furthermore, the reverse thrust beam includes more than one convex beam 8, which are arranged at equal intervals along the inclined reverse thrust tie rod beam 9. The top of the convex beam 8 is connected to the bottom of the reverse thrust grate group 3, and the left and right ends of the convex beam 8 are mounted on the left and right sides of the reverse thrust tie rod beam 9.

[0034] Since the reverse grate group 3 is divided into a fixed reverse grate 30 and a movable reverse grate 31, the two are installed in a layer-by-layer overlapping manner like stairs. The movable reverse grate 31 needs to be fixed on the convex beam 8 to facilitate the pulling of the reverse push rod beam 9, and the fixed reverse grate 30 does not need to move with the reverse push rod beam 9. Therefore, a transversely fixed grate fixing beam Ⅰ42 is also built between the isolation walls, and the fixed reverse grate 30 is built on the grate fixing beam Ⅰ, so that the grate fixing beam Ⅰ42 and the convex beam are arranged at intervals to ensure the normal movement of the reverse grate group 3 in the middle of the isolation wall.

[0035] Furthermore, the forward push beam includes more than one concave beam 7, which are arranged at equal intervals along the inclined forward push pull rod beam 10. The left and right ends of the concave beam 7 are mounted on the left and right sides of the forward push pull rod beam 10, and the middle recessed portion of the concave beam 7 is lower than the middle protruding portion of the convex beam 8.

[0036] Since the push grate group 2 is composed of a fixed push grate 20 and a movable push grate 21, both of which are also installed in a stair-like manner with one layer overlapping another, the movable push grate 21 needs to be fixed on the concave beam to facilitate the pull of the push rod beam, and the fixed push grate 20 does not need to move with the push rod beam 10, so grate fixed beams II 43 are also built on the left and right outer layers of the isolation wall 4, and the grate fixed beam II 43 is built between the isolation wall and the left rod beam bracket 5, and between the isolation wall 4 and the right rod beam bracket 6. Similarly, the grate fixed beam II 43 and the concave beam 7 are arranged at intervals to ensure the normal movement of the push grate group 2 outside the isolation wall 4.

[0037] In order to ensure that each row of grate groups is at the same height on the slope of the same slope, the upper slope beam 61, the lower slope beam 62, and the left and right sides of the forward push rod beam 10 and the reverse push rod beam 9 are all in a staircase structure (such as Figure 6 As shown in the exploded view of FIG. 1 , the staircase structure is divided into an inclined part and a horizontal part, wherein the left and right ends of the convex beam 8 and the concave beam 7 are mounted on the horizontal part. In this way, the height difference of each row of the grate group can be controlled to be the same, so that garbage can be transported in the furnace bed like a staircase structure.

[0038] It should be noted that the isolation wall 4 is arranged to cross and space two groups of forward-pushing grates and one group of reverse-pushing grates, and the design and fixing method of the convex beam 8 and the concave beam 7 are to avoid each other and the isolation wall, so as to fix a number of movable and fixed grates in a limited space.

[0039] A hinged component 80 for mounting the reverse grate group 3 is provided on the top surface of the middle protruding part of the convex beam 8, and a hinged component 80 for mounting the forward grate group is provided on the top surfaces of the left and right ends of the concave beam. The hinged component 80 is mainly composed of a clamping plate and a hinge shaft. The clamping plate is inclined and protrudes from the top surface of the beam body of the convex beam and the concave beam. The hinge shaft is installed on the top of the clamping plate along the length direction of the clamping plate. A clamping groove is provided at the bottom of the grate of the reverse grate group and the forward grate group, and the clamping groove is rotatably mounted on the hinge shaft.

[0040] In order to fix the fixed grate in the lowest horizontal row of the hearth, a reverse grate pressing plate 16 is provided at the bottom of the inner side of the two isolation walls. The reverse grate pressing plate 16 is installed to press the reverse grate group in the lowest row. A forward grate supporting plate 17 is provided at the bottom of the outer side of the two isolation walls. The forward grate group in the lowest row is placed on the forward grate supporting plate 17.

[0041] The upper ends of the reverse push rod beam 9 and the forward push rod beam 10 are respectively provided with power devices, and a fixed plate 15 fixed to the inner support frame and the outer support frame is provided at the inclined uppermost end of the two isolation walls. The power device is composed of a pull rod driver 14 and a multi-degree-of-freedom hinged connecting rod 18. The upper ends of the multi-degree-of-freedom hinged connecting rod 18 are respectively rotatably connected to the upper ends of the reverse push rod beam 9 and the forward push rod beam 10, and the lower end of the multi-degree-of-freedom hinged connecting rod 18 is installed on the fixed plate 15. The driving end of the pull rod driver 14 is hinged at the middle part of the multi-degree-of-freedom hinged connecting rod 18, which is used to drive the reverse push rod beam 9 and the forward push rod beam 10 to move along the inclined lower slope beam 62 and upper slope beam 61.

[0042] The overall working principle of the hearth is as follows:

[0043] like Figure 6 As shown, the reverse push rod beam 9 and the forward push rod beam 10 are in a rectangular frame structure, the left and right beams of the reverse push rod beam 9 are cooperatively mounted on the lower roller 64, and the left and right beams of the forward push rod beam 10 are cooperatively mounted on the upper roller 63. The grate fixed beam Ⅰ42 and the grate fixed beam Ⅱ43 are not driven by power. The upper ends of the reverse push rod beam 9 and the forward push rod beam 10 are respectively provided with pull rod drivers. When pulled, they are supported by the upper and lower rollers (63, 64), so they can move back and forth along the length direction of the isolation / 4, so the movable forward push grate 21 and the movable reverse push grate 31 connected to the convex beam 8 and the concave beam 7 can swing back and forth.

[0044] That is Figure 7 As shown, it is equivalent to the pull rod driver (hydraulic cylinder) driving the reverse push rod beam 9 and the forward push rod beam 10 to move respectively, and the speed can be adjusted respectively. When the forward push rod beam 9 moves, it pulls the concave beam 7 to move, and drives the movable grate of the forward push grate group 2 outside the partition wall 4 to move. Since the grate fixed beam II 43 pulls the fixed forward push grate 20, the entire fixed forward push grate 20 of the furnace bed is inactive, and the spaced forward push movable grate 20 is driven back and forth by the concave beam 7, so as to cooperate with the fixed forward push grate 20 to break up and stir the garbage. Similarly, the movable reverse push grate 31 and the fixed reverse push grate 30 on the reverse push grate group 3 are also assembled in the same way. The movable and fixed reverse push grates assembled on the convex beam 8 are rubbed back and forth to achieve the purpose of stirring the garbage. This design structure is also different from the existing structure.

[0045] Look again Figure 2 In order to ensure that the entire furnace bed can be replaced and moved as a whole, the bottom of the left tie rod beam bracket and the right tie rod beam bracket are fixed with moving wheels. There is also a set of support frames under the isolation wall, the bottom of which is welded with the left tie rod beam bracket 5 and the right tie rod beam bracket 6, and moves by moving wheels.

[0046] The above is a detailed introduction to a grate group staggered support system for alternating transverse concave and convex forward and reverse thrust provided by the present application. The description of the specific embodiment is only used to help understand the method and its core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
