Description

Technical Field

[0001] The utility model relates to the technical field of RTO thermal storage combustion equipment, in particular to an RTO thermal storage combustion equipment with top drainage. Background Art

[0002] RTO (Regenerative Toilet Gas) thermal storage combustion equipment is widely used in waste gas treatment. RTO equipment is typically placed outdoors, and water easily accumulates on the top of the RTO furnace after rain or snow. Prolonged water accumulation can easily cause equipment corrosion and lead to environmental problems such as waste gas leakage. Therefore, reducing water vapor in waste gas treatment equipment is essential.

[0003] The patent document with publication number CN217329820U discloses an RTO heat storage combustion furnace device with a waterproof structure design, including a three-tower RTO body, and a furnace top is provided on the top of the outer shell of the three-tower RTO body; the cross-section of the furnace top is set in an inverted "V" shape to prevent water accumulation on the furnace top, and the bottom of the furnace top is welded to the transverse reinforcement ribs on the top of the outer shell, the furnace top is bent downward from the middle to both sides, and the top of the furnace top is welded with top reinforcement ribs along its transverse direction, and the two sides of the furnace top extend horizontally outward to form an edge; multiple mounting plates are fixed to the side of the outer shell, and a slot is opened downward on the top of the mounting plate, and an insert plate that can be inserted into the slot is fixed to the bottom of the edge.

[0004] This prior art suffers from an unstable installation problem with the furnace roof on the RTO equipment. The specific reason is that the tops of the several transverse reinforcing ribs are essentially on the same horizontal plane, while the furnace roof is in an inverted V shape. When the furnace roof is installed on the transverse reinforcing ribs, only the two long straight sides of the furnace roof can abut the ends of the transverse reinforcing ribs. This inevitably leaves gaps between the two short inverted V-shaped sides of the furnace roof and the transverse reinforcing ribs, as well as between the middle portion of the furnace roof and the transverse reinforcing ribs. Consequently, when the furnace roof is welded and fixed, only the two long straight sides of the furnace roof are actually connected and fixed, resulting in a small connection area and unstable installation. Furthermore, the transverse reinforcing ribs are spaced apart, which means that the two long straight sides of the furnace roof are spot-welded to the ends of each transverse reinforcing rib, further reducing the welding area and causing unstable installation. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a top-draining RTO heat storage combustion device with a stable drainage top.

[0006] The technical solution to the problem solved by the present invention is to provide an RTO thermal storage combustion device with top drainage, comprising an equipment body, wherein a plurality of reinforcing ribs are provided on the top of the equipment body; and further comprising an inverted V-shaped drainage top arranged on the top of the equipment body; the drainage top is connected to the equipment body through a connecting structure; the connecting structure comprises a main board and side panels vertically connected to the side edges of the main board, one side of the main board abuts against the plurality of reinforcing ribs on the top of the equipment body, and the other side is provided with a plurality of dry abutting members, and the abutting members all abut against the drainage top; and the side edges of the main board are welded to the drainage top or / and connected through a closing plate; and the side panels are connected to the side faces of the equipment body.

[0010] As a preferred embodiment of the present invention, the abutting portion is provided with two clamping plates, and a slot for inserting the reinforcing rib is formed between the two clamping plates.

[0017] 1. In the present application, a connection structure is added to improve the installation stability of the drain top on the RTO thermal storage combustion equipment body. Specifically: first, the connection structure increases the connection area by the face-to-face connection between its side plates and the side surfaces of the equipment body, so as to improve the installation stability of the connection structure on the equipment body; second, first, the long side of the main board of the connection structure is fully welded to the long straight side of the drain top, rather than the spot welding in the prior art, thereby increasing the fixing area of ​​the drain top; second, a closing plate is added to the short side of the main board of the connection structure to be fully welded to the short inverted V-shaped side of the drain top, thereby further increasing the fixing area of ​​the drain plate; third, the main board of the connection structure and the drain top are supported by a number of abutment parts, thereby increasing the supported area of ​​the drain top; based on this, the installation stability of the drain top on the connection structure is improved; and finally, the installation stability of the drainage structure on the RTO thermal storage combustion equipment body is improved.

[0018] 2.

[0028] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] A top drainage RTO thermal storage combustion equipment, such as Figure 1 and Figure 2 As shown, the RTO thermal storage combustion device body 1 is generally provided with reinforcing ribs 11 on the front, side and top surfaces of the device body 11 in order to improve the strength of the device body 1. Since the top of the device body 1 is basically flat, it is easy for water to accumulate on the top after rain or snow, which may cause corrosion to the device. Figure 1 As shown, in the present application, an inverted V-shaped drainage top 2 is provided on the top of the equipment body 1 as the new top of the equipment body 1. The drainage top 2 includes four side edges, namely two long straight edges 21 and two short inverted V-shaped edges 22. Water can slide down along the direction of the short inverted V-shaped edges 22, and then fall from the front and back of the equipment body 1, thereby achieving the effect of top drainage.

[0030] Since the top of the equipment body 1 is basically planar, and the drainage top 2 is non-planar, if the two are directly connected and installed, there will be a problem of unstable installation due to the mismatch between the surfaces. Therefore, in this application, a connecting structure is also added, and the drainage top 2 is connected to the equipment body 1 through the connecting structure.

[0031] like Figure 3 、 4As shown in Figures 5 and 6, the connection structure includes a main board 31. The main board 31 includes four side edges, namely a long side 311 parallel to the long straight side 21 of the drain top 2, and a short side 312 perpendicular to the long side 311. At the same time, the main board 31 includes a main body located between the long side 311 and the short side 312, namely a support portion 313. The two ends of the long side 311 do not exceed the two ends of the long straight side 21 of the drain top 2, and the two ends of the short side 312 do not exceed the two ends of the short inverted V-shaped side 22 of the drain top 2, so as to ensure that water on the drain top 2 does not flow to the connection structure. A plurality of abutment members 34 are provided on one surface of the support portion 313. The shape and structure of the abutment members 34 are not limited and can be plates, columns, etc. In the present application, the abutment members 34 are configured as columnar structures. The connection structure also includes side panels 32 perpendicularly connected to the side edges of the main board 31. The number of side panels 32 is not limited and can be one, two, three, or four. In the present application, to ensure the installation strength of the connection structure and facilitate installation of the connection structure, three side panels 32 are provided, respectively connected to the two long sides 311 and one short side 312 of the main board 31. Preferably, the main board 31 and side panels 32 of the connection structure are integrally formed. In addition, in some embodiments, because some device bodies 1 also have an exhaust port on the top, openings are also provided on the main board 31 and the drain top 2, and it is necessary to connect the openings and the exhaust port via an exhaust pipe.

[0032] During installation, first, the connection structure and the drain top 2 can be installed together on the ground. Specifically, the connection structure is placed flat with the main board 31 facing upward. In order to maintain the balance of the connection structure, support legs and other structures can be added between the main board 31 and the ground. The drain top 2 is then overlapped onto the main board 31, with the long straight side 21 of the drain top 2 abutting against the long side 311 of the main board 31. The height of each abutment 34 is adjusted so that the free end of the abutment 34 can abut against its corresponding part of the drain top 2. Then, according to the shape and size of the gap between the short inverted V-shaped side 22 and the short side 312, the corresponding closing plate 33 is cut out and the closing plate 33 is filled into the gap. Finally, the long straight side 21 is welded to the long side 311, and the closing plate 33 is welded to the short inverted V-shaped side 22 and the short side 312.

[0033] Among them, since the drain top 2 is an inclined surface, the abutment 34 at different positions needs to have different heights in order to abut against the corresponding part of the drain top 2, which causes the problem of inconvenience in adjustment. In some embodiments, a height-adjustable abutment 34 is designed to solve this problem. Specifically: the main board 31 includes an abutment portion for abutting against the reinforcing rib 11, and an adjustment portion located between two adjacent abutment portions; the adjustment portion is provided with a guide hole 314, and the abutment 34 is connected to the guide hole 314 through a height adjustment structure, and the opening of the guide hole 314 at one end away from the drain top forms a control port. The height adjustment structure is not limited. For example, as in the present embodiment, the height adjustment structure includes a threaded column connected to the abutment 34, and an internal thread provided on the inner wall of the guide hole 314. The threaded column is threadedly connected to the internal thread, and an inner hexagonal hole is provided at the end of the threaded column close to the control port. Then, when installing the connection structure and drain top 2, you can directly weld the long straight side 21 to the long side 311 first, and weld the closing plate 33 to the short inverted V-shaped side 22 and the short side 312, without considering whether the abutment 34 abuts the drain top 2. After welding, insert a screwdriver into the hexagonal hole and control the threaded column to drive the abutment 34 to spirally move until it abuts the drain top 2.

[0034] Similarly, since the drain top 2 is a slope, in order to ensure that the abutment 34 is completely in contact with the drain top 2, the free end surface of the abutment 34 is preferably also set to a corresponding slope. However, due to the inevitable existence of manufacturing errors that affect the complete abutment effect between the free end surface of the abutment 34 and the drain top 2, in some embodiments, a deformable flexible pad can be provided at the end of the abutment 34 used to abut the drain top 2, such as a soft pad filled with sand or foam particles, which can fully fit the shape of the drain top 2 through its deformability; in addition, the flexible contact surface can also provide a buffering effect to prevent the abutment 34 from pushing the drain top 2 to deform due to excessive adjustment during the height adjustment process.

[0035] Furthermore, since the drain top 2 is already supported and reinforced by the abutment member 34 and is less prone to deformation, there is no need to add top reinforcement ribs to the top surface of the drain top 2. This allows the top of the drain top 2 to form a smooth, seamless drainage surface, improving drainage efficiency. In some embodiments, a non-stick layer, such as polytetrafluoroethylene cloth, can be added to the top of the drain top 2, i.e., the side facing away from the device body 1, to further improve drainage efficiency.

[0036] After completing the connection between the drainage top 2 and the connection structure, the entire structure is installed on the top of the device body 1. During installation, the entire structure is lifted to the top of the device body 1 so that the main board 31 abuts against the several reinforcing ribs 11 on the top of the device body 1; at the same time, the side panels 32 are connected to the sides of the device body 1, and the connection method can be through a screw and nut structure or welding. In some embodiments, since the side of the device body 1 also has reinforcing ribs, the part of the side panel 32 that can abut against the reinforcing ribs can be welded to the reinforcing ribs, and the part of the side panel 32 that cannot abut against the reinforcing ribs and the side are filled with a water stop, and then connected by a screw and nut structure.

[0037] In some embodiments, to improve the abutment strength of the mainboard 31 on the device body 1, two clamping plates 315 are provided on the abutment portion of the mainboard 31. A slot is formed between the two clamping plates 315 for inserting the reinforcing rib 11. The clamping structure between the slot and the reinforcing rib 11 improves the installation strength. In some embodiments, a rubber pad can be provided on the inner wall of the slot to further improve the clamping strength.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
