Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of coke oven maintenance equipment, and specifically relates to a maintenance auxiliary equipment. Background Art
[0002] A coke oven is a furnace used to refine coke. In the long-term production process, as the age of the coke oven increases and the number of coke pushing increases, the coke oven's carbonization chamber wall and furnace bottom will also have various problems such as depression, pockmarks, and caves. In order to repair these problems and minimize damage to the carbonization chamber masonry, hot repair is often used. Considering the large volume of the conventional 7.63m coke oven carbonization chamber and environmental protection requirements, the surface problems of the carbonization chamber wall and furnace bottom can only be dealt with after the coke pushing is completed. However, the temperature of the furnace wall is very high after the coke pushing, which has a great impact on the operators and affects the operating efficiency. When the operation time is long, the furnace temperature will also drop significantly, affecting the subsequent production operations of the coke oven. Summary of the invention
[0003] In order to solve the technical problem that the temperature inside the coke oven has a great impact on the operators during the thermal repair of the coke oven, the present application provides a maintenance auxiliary equipment.
[0004] In a first aspect of the present application, a maintenance auxiliary device is provided, comprising:
[0005] A box body, the box body comprising a first side wall and a second side wall arranged opposite to each other and a third side wall and a fourth side wall arranged opposite to each other; an operation entrance is arranged at the lower end of the first side wall; a plurality of operation openings are arranged on the third side wall, and each of the operation openings is provided with a door panel to cover the corresponding operation opening;
[0006] An air inlet pipe is arranged on the first side wall, and an air outlet of the air inlet pipe is arranged in the box body.
[0007] In some embodiments, the third side wall includes a plurality of horizontally arranged transverse reinforcing ribs, and a gap between two adjacent transverse reinforcing ribs is the operation port.
[0008] In some embodiments, the top and bottom surfaces of the transverse reinforcement ribs are provided with sliding grooves, the length direction of the sliding grooves is parallel to the length direction of the transverse reinforcement ribs, at least two of the door panels are arranged between two adjacent transverse reinforcement ribs, and the top and bottom ends of the door panels are respectively slidably arranged in the adjacent sliding grooves.
[0009] In some embodiments, the third side wall further includes at least one longitudinal reinforcing rib, the at least one longitudinal reinforcing rib is vertically arranged, and the longitudinal reinforcing rib is connected to each of the transverse reinforcing ribs.
[0010] In some embodiments, the air inlet pipe is disposed at an upper end of the first side wall.
[0011] In some embodiments, a distance between the air outlet of the air inlet pipe and the first side wall is greater than a distance between the air outlet of the air inlet pipe and the second side wall.
[0012] In some embodiments, the fourth side wall is also provided with a plurality of operation openings, and each of the operation openings on the fourth side wall is provided with a door panel to shield the corresponding operation opening.
[0013] In some embodiments, a plurality of rollers are disposed at the bottom end of the box.
[0014] In some embodiments, at least one of the rollers is provided with a locking structure.
[0015] In some embodiments, the inner walls of the first side wall, the second side wall, the third side wall and the fourth side wall are all provided with thermal insulation pads.
[0016] According to the maintenance auxiliary equipment provided by one or more embodiments of the present application, a box body is set, and multiple operation ports and corresponding door panels are set on the third side wall of the box body. When the operator inspects the inner wall of the coke oven, only the door panel of the operation port at the corresponding position can be opened, which can greatly reduce the path of heat in the coke oven entering the box body, thereby slowing down the heating rate in the box body, providing the operator with a longer and comfortable working environment, reducing the impact of the high temperature in the coke oven on the operator, so that the operator can perform maintenance efficiently. After the maintenance is completed, the heat dissipation in the coke oven is also less, and the impact on subsequent coke oven production operations is small; the air intake pipe is used to introduce the lower temperature air outside the coke oven into the box body. The air entering the box body through the air intake pipe is discharged from the operation inlet after absorbing heat, which can keep the temperature in the box body for a long time, and maintain a more comfortable working environment in the box body.

DETAILED DESCRIPTION
[0020] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0021] Figure 1 A three-dimensional structural schematic diagram of the maintenance auxiliary equipment in one or more embodiments of the present application is shown. Figure 2 Shows Figure 1 The cross-sectional structure diagram of the auxiliary equipment for maintenance. Figure 2 The black arrows shown are the air flow direction in the intake pipe and the box.
[0022] See also Figure 1 and Figure 2 According to a first aspect of the present application, there is provided a maintenance auxiliary device, including a box body 100 and an air intake pipe 200 .
[0023] See also Figure 1 The box body 100 includes a first side wall 110 and a second side wall 120 disposed oppositely, and a third side wall 130 and a fourth side wall 140 disposed oppositely; an operation entrance 111 is disposed at the lower end of the first side wall 110; the third side wall 130 is disposed with a plurality of operation ports, each of which is provided with a door panel 170 to shield the corresponding operation port. The air inlet 200 is disposed on the first side wall 110, and the air outlet of the air inlet 200 is disposed in the box body 100.
[0024] The box body 100 includes a bottom wall and a top wall, and a first side wall 110, a second side wall 120, a third side wall 130 and a fourth side wall 140 are arranged between the bottom wall and the top wall to form the box body 100 together. The box body 100 is a heat-insulating space with a certain volume, which can isolate the heat of the carbonization chamber in the coke oven to a certain extent. Among them, the operation entrance 111 is an entrance for operators to enter the box body 100. When the operator is in the box body 100, the hands and working tools can be extended from the box body 100 through the operation opening to inspect the side wall or bottom surface of the coke oven. The third side wall 130 is provided with a plurality of operation openings, and each operation opening is provided with a door panel 170. When the operator inspects the inner wall of the coke oven, only the door panel 170 of the operation opening at the corresponding position can be opened, which can greatly reduce the path of the heat in the coke oven entering the box body 100, thereby slowing down the heating rate in the box body 100, providing the operator with a longer and comfortable working environment, reducing the impact of the high temperature in the coke oven on the operator, and allowing the operator to perform inspections efficiently. After the inspection is completed, the heat dissipation in the coke oven is also relatively small, which has little impact on the subsequent coke oven production operations.
[0025] The air inlet pipe 200 is used to introduce the lower temperature air outside the coke oven into the box body 100. The air entering the box body 100 through the air inlet pipe 200 absorbs heat and is discharged from the operation inlet 111, so that the temperature inside the box body 100 can be maintained for a long time, maintaining a more comfortable working environment inside the box body 100.
[0026] Of course, when the area in the coke oven that needs to be repaired is large, the operator can choose to open one door panel 170 first, and after the defects at the corresponding operating port are handled, close the operating port, and then open the adjacent door panel 170 to reduce the amount of hot air in the coke oven entering the box body 100.
[0027] In some embodiments, the side walls of the box 100 can be made of high-strength and non-flammable materials, such as stainless steel plates, iron plates, etc. Figure 1 and Figure 2 In some embodiments, the third side wall 130 includes a plurality of horizontally arranged transverse reinforcing ribs 150, and the gap between two adjacent transverse reinforcing ribs 150 is the operation port.
[0028] The third side wall 130 is separated into a plurality of operating openings by means of reinforcing ribs. On the one hand, this can ensure that the box body 100 still has strong strength and is not easily damaged. On the other hand, the reinforcing ribs are stronger than ordinary side walls of the box body 100, but are not very high in the height direction of the box body 100. The reinforcing ribs block less parts, and the operating range for operators is large. It is not easy for defects and damages on the coke oven side wall to be blocked by the third side wall 130 and thus be inconvenient to repair.
[0029] In some embodiments, the top and bottom surfaces of the transverse reinforcement ribs 150 are provided with sliding grooves, the length direction of the sliding grooves is parallel to the length direction of the transverse reinforcement ribs 150, at least two door panels 170 are arranged between two adjacent transverse reinforcement ribs 150, and the top and bottom ends of the door panels 170 are respectively slidably arranged in the adjacent sliding grooves.
[0030] It can be understood that the area of the door panel 170 can be made smaller than the area of the corresponding operating port, and multiple door panels 170 can be set. The door panels 170 are slidably set between the reinforcing ribs. The position and size of the connection with the coke oven in the box body 100 can be changed by pushing and pulling. That is, at this time, the cooperation between the door panel 170 and the transverse reinforcing rib 150 is similar to the cooperation between the window and the glass window door.
[0031] Of course, in some embodiments, the door panel 170 can also be hinged on the reinforcing rib. In other embodiments, the reinforcing rib is made of a magnetic material, and a magnet is provided on the door panel 170. The door panel 170 is provided on the reinforcing rib by magnetic attraction, which is convenient for disassembly and assembly, and has a larger operating opening when in use.
[0032] In order to facilitate the movement of the door panels 170 , each door panel 170 is provided with a handle 171 . The handle 171 may be provided on the surface of the door panel 170 facing the interior of the box 100 , so as to facilitate the operation of the operator in the box 100 .
[0033] See also Figure 1 and Figure 2 The third side wall 130 further includes at least one longitudinal reinforcing rib 160 , which is vertically arranged and connected to each transverse reinforcing rib 150 .
[0034] The strength of the third side wall 130 is enhanced by the longitudinal reinforcing ribs 160 to prevent the gravity of the door panel 170 from affecting the transverse reinforcing ribs 150, causing the transverse reinforcing ribs 150 to deform, thereby preventing the door panel 170 from getting stuck due to the deformation of the slide groove, thereby increasing the service life of the box body 100.
[0035] See also Figure 1 and Figure 2 In some embodiments, the air inlet pipe 200 is disposed at the upper end of the first side wall 110 .
[0036] The air intake pipe 200 is located in the direction of the operation inlet 111, which can avoid the position of the air intake pipe 200 affecting the operation inlet 111, and the air intake pipe 200 is located above the inside of the box 100, which can reduce the impact on the operator and does not affect the operator's work in the box 100. On the other hand, the air in the air intake pipe 200 is lower in temperature than the air in the box 100. The air in the air intake pipe 200 is arranged above the inside of the box 100, and the air flowing out of the air outlet of the air intake pipe 200 will sink, absorb heat, and then flow out from the operation inlet 111, and stay in the box 100 for a long time, so it can absorb and take away more heat.
[0037] See also Figure 2 In some embodiments, the distance between the air outlet of the air inlet pipe 200 and the first side wall 110 is greater than the distance between the air outlet of the air inlet pipe 200 and the second side wall 120 .
[0038] That is, the air outlet of the air intake pipe 200 is closer to the first side wall 110 , so that when the air in the air intake pipe 200 flows into the box body 100 , the flow path of the air then flows out of the box body 100 is longer and covers a larger range, which has a good cooling effect on the interior of the box body 100 .
[0039] In some embodiments, the air inlet of the air inlet pipe 200 is connected to a blower to introduce air into the box 100. When the coke oven is repaired, the auxiliary maintenance equipment is located inside the coke oven, and the blower is arranged outside the coke oven to obtain air at room temperature or low temperature, and to prevent the high temperature in the coke oven from affecting the operation of the blower. The blower can be a fan.
[0040] An organ pipe is also provided between the blowing device and the air inlet of the air inlet pipe 200. Both the organ pipe and the air inlet pipe 200 are made of high temperature resistant materials, and the organ pipe is retractable, which will not affect the position where the operator places the box 100.
[0041] See also Figure 1 The fourth side wall 140 is also provided with a plurality of operation openings, and each operation opening on the fourth side wall 140 is provided with a door panel 170 to shield the corresponding operation opening.
[0042] That is, the operator can operate on the inner wall of the coke oven through the third side wall 130 and the fourth side wall 140 of the box body 100. The operator does not need to frequently walk out of the box body 100 to change the direction of the third side wall 130 of the box body 100, and can repair the inner wall of the coke oven in multiple directions and positions, thereby improving the operator's maintenance efficiency.
[0043] See also Figure 1 and Figure 2 In some embodiments, a plurality of rollers 300 are disposed at the bottom end of the box 100 .
[0044] The operator can directly push the box 100 to move, and the box 100 can quickly enter the coke oven or be quickly moved out of the coke oven, which further shortens the maintenance time of the operator, improves the maintenance efficiency, and also reduces the heat loss in the coke oven.
[0045] In some embodiments, at least one roller 300 is provided with a locking structure.
[0046] After the box 100 is moved into the coke oven, the roller 300 is locked by the locking structure, which can avoid safety accidents caused by the displacement of the box 100 when the operator is in the box 100, thereby improving the safety of the operation. The locking structure can be any device that can lock the roller 300. For example, the side wall of the box 100 can be provided with two universal wheels and two brake wheels 310, and the brake wheel 310 is the roller 300 with a locking structure.
[0047] After the inspection is completed, the operator walks out of the box body 100, unlocks the roller 300, and pushes the box body 100 out of the coke oven.
[0048] In some embodiments, the inner walls of the first side wall 110, the second side wall 120, the third side wall 130 and the fourth side wall 140 are all provided with heat insulation pads. The heat insulation pads can further reduce the speed at which the temperature in the box 100 rises by heat transfer from the heat in the coke oven, thereby providing a more comfortable working environment for the operators. For example, the heat insulation pads can be glass wool.
[0049] Of course, the first side wall 110, the second side wall 120, the third side wall 130, the fourth side wall 140 and the door panel 170 can all be hollow structures, and the thermal insulation pad can be arranged in the interlayer of the first side wall 110, the second side wall 120, the third side wall 130, the fourth side wall 140 and the door panel 170, which can reduce the possibility of the thermal insulation pad being damaged during the operation process and reduce the cost of use.
[0050] In some embodiments, the length of the box body 100 may be 1.5-2.5m, the width may be 0.5m-0.55m, and the height may be 2m-2.5m, wherein the first side wall 110 and the second side wall 120 are located in the width direction of the box body 100, and the third side wall 130 and the fourth side wall 140 are located in the length direction of the box body 100, that is, the areas of the third side wall 130 and the fourth side wall 140 are both larger than the areas of the first side wall 110 and the second side wall 120, so that the box body 100 has more operating openings for operators to operate conveniently.
