AI Technical Summary
Due to the large weight and open structure of the traditional garbage incinerator, the manhole door design makes it difficult to open and close the manhole, and the manhole is occupied when opened, which limits the size of the manhole, which in turn affects the convenience of maintenance.
A manhole door structure of a garbage incineration furnace is designed, using a manhole door base, guide beam, support rail, upper and lower pulleys and locking structure to realize the horizontal opening and closing of the manhole door cover, ensuring the easy operation of the door and large-size design.
It realizes convenient opening and closing of the manhole door, avoids occupancy of the furnace rear platform when opening, expands the size of the manhole, and improves the convenience and efficiency of maintenance.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage incineration, in particular to a manhole door structure of a garbage incineration furnace. Background Art
[0002] The waste incinerator has a manhole on the rear wall of the furnace, which is used to enter the furnace for maintenance work such as replacing the grate pieces and cleaning the coke. The traditional manhole design is hinged outward-opening, but because the manhole door needs to be laid with refractory castables, it is heavy, which makes it difficult to open and close the manhole because of the large friction between it and the fixed boiler assembly. In addition, the traditional manhole door is outward-opening, and after opening, it occupies the platform behind the furnace. The above reasons lead to a small manhole size, resulting in unchanged maintenance. Summary of the invention
[0003] In order to solve the above technical problems, the utility model provides a manhole door structure for a garbage incineration furnace, which can conveniently realize the opening and closing of the manhole door, and does not occupy the platform behind the furnace when opened, thereby realizing a large-size design of the manhole.
[0004] The technical solution is as follows: a manhole door structure of a garbage incineration furnace, comprising a manhole door base arranged on the rear wall of the incineration furnace, a manhole door cover installed at the manhole door of the manhole door base, characterized in that a guide beam is installed on the upper part of the manhole door base and a supporting guide rail is arranged on the lower part, an upper pulley cooperating with the guide beam is arranged on the top of the manhole door cover, and a lower pulley cooperating with the supporting guide rail is arranged on the bottom, the manhole door cover is opened horizontally, and locking structures are arranged on both sides of the manhole door cover.
[0005] It is further characterized in that the locking structure comprises a channel steel with a U-shaped groove and a swingable screw with a nut, and the screw is inserted into the U-shaped groove and locked by the nut to achieve the closing of the manhole door cover;
[0006] The manhole door of the manhole door base is provided with notches around its periphery, and aluminum silicate fiber ropes are embedded in the notches.
[0007] After the utility model is adopted, the lower part of the manhole door cover is supported by a lower pulley and the upper part is guided by a guide beam, so that the manhole door cover can be easily moved horizontally to complete opening and closing. Moreover, when the manhole door cover is opened, there is no need to occupy the platform behind the furnace. The size of the manhole door cover is not limited, and a large-size design of the manhole can be realized. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is the front view of the structure of the utility model;
[0009] Figure 2 This is a left view of the structure of the utility model; DETAILED DESCRIPTION
[0010] See Figure 1 , Figure 2 As shown, a manhole door structure of a garbage incineration furnace comprises a manhole door base 1 arranged on the rear wall of the incineration furnace, a manhole door cover 4 is installed at the manhole door of the manhole door base 1, a guide beam 2 is installed on the upper part of the manhole door base 1, and a supporting guide rail 3 is arranged on the lower part, an upper pulley 5 matched with the guide beam 2 is arranged on the top of the manhole door cover 4, and a lower pulley 6 matched with the supporting guide rail 3 is arranged on the bottom, the upper pulley 5 is arranged horizontally, and cooperates with the guide beam 2 to achieve good guidance, the lower pulley 6 is arranged vertically, and mainly plays a supporting role, and two groups of four in total are arranged according to needs, and the manhole door cover 4 is opened horizontally, that is, it moves on the supporting guide rail 3 to open.
[0011] In order to allow the manhole door cover 4 to be closed smoothly, locking structures are provided on both sides of the manhole door cover 4. The locking structure includes a channel steel 8 with a U-shaped groove and a swingable screw rod 7 with a nut 9, that is, the end of the screw rod 7 is hinged on the manhole door base 1, and the screw rod 7 is inserted into the U-shaped groove and locked by the nut 9 to realize the closing of the manhole door cover 4. When the manhole door cover 4 needs to be opened, it is only necessary to loosen the nut 9 to allow the screw rod 7 to swing out of the U-shaped groove, and the manhole door cover 4 is not restricted and can be moved horizontally to open.
[0012] The manhole door of the manhole door base 1 is provided with slots around it, and an aluminum silicate fiber rope 10 is embedded in the slots to ensure the sealing between the manhole door cover 4 and the manhole door base 1.
