Description

Technical Field

[0001] The utility model belongs to the field of switches, in particular to an automatic reversing heating device for a ramming coke oven. Background Art

[0002] As an important device in the coke oven heating system, the gas exchanger is mainly used to change the gas flow direction of the coke oven heating system. Through the Siemens PCS7 control system, hydraulic cylinders, pull rods, chains and other transmission devices, the exchange cock, exhaust gas pan rod and air cover are automatically switched regularly to change the flow direction of gas, air and exhaust gas, and the heating of the coke oven carbonization chamber is achieved through the exchange of gas and exhaust gas.

[0003] In the prior art, since gas exchangers are usually used in the environment around coke ovens, a certain amount of smoke and dust will be generated during the use of coke ovens. In order to avoid the internal temperature of the control box being too high and affecting the operation of the exchanger, a heat dissipation port is generally opened on the control box shell. However, as the air flows, the smoke and dust may enter the interior of the control box through the heat dissipation port, causing the dust in the smoke to adhere to the internal electrical components of the control box, thereby affecting the heat dissipation effect of the electrical components, and further causing the electrical components to overheat and short-circuit, thereby affecting the normal use of the switch.

[0004] To this end, we provide a ramming coke oven automatic reversing heating device to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figure 1-7 The utility model is an automatic reversing heating device for a ramming coke oven, comprising a bottom plate 1, a gas exchanger 2 and a control box 3 are fixedly connected to the upper surface of the bottom plate 1;

[0033] The control box 3 is provided with a plurality of heat dissipation ports 4, a positioning block 5 is fixedly connected to the rear surface of the control box 3, two limit rods 6 are fixedly connected to the inner surface of the positioning block 5, sliders 7 are slidably connected to the outer surfaces of the two limit rods 6, the two sliders 7 are fixedly connected to the same connecting ring 8, an activated carbon filter screen 9 is movably connected to the inner surface of the connecting ring 8, a first connecting block 10 is fixedly connected to the upper surface of the connecting ring 8, a second connecting block 15 is fixedly connected to the upper surface of the activated carbon filter screen 9, and a handle 11 is fixedly connected to the rear surface of the second connecting block 15.

[0034] Specifically, a spring 12 is slidably sleeved on the outer surface of the limit rod 6, one end of the spring 12 is fixedly connected to the upper surface of the slider 7, and the end of the spring 12 away from the slider 7 is fixedly connected to the side inner wall of the positioning block 5. An anti-slip groove 13 is provided on the positioning block 5, and the outer surface of the slider 7 is slidably connected to the anti-slip groove 13. A slide groove 14 is provided on the positioning block 5, and the outer surface of the connecting ring 8 is slidably connected to the slide groove 14. The outer surface of the activated carbon filter 9 is movably connected to the slide groove 14. Through the setting of the spring 12, the activated carbon filter 9 can quickly enter the slide groove 14, and through the setting of the anti-slip groove 13, the moving distance and direction of the slider 7 are limited. Specific embodiment 2

[0036] See also Figure 1-7 On the basis of the specific embodiment 1, a docking groove 16 is provided on the connecting ring 8, and the outer surfaces of the activated carbon filter 9 and the second connecting block 15 are movably connected to the docking groove 16. The activated carbon filter 9 is located on one side of the heat dissipation port 4, and the control box 3 is located on one side of the gas switch 2. A taking groove 17 is provided on the positioning block 5. The number of the taking grooves 17 is two and they are distributed on the left and right. The front surface of the first connecting block 10 is in contact with the control box 3, and the limit rod 6 passes through the slider 7.

[0037] Specifically, by setting the taking groove 17, the disassembly of the activated carbon filter 9 is avoided. At the same time, the first connecting block 10 is in contact with the control box 3 to prevent dust from entering the control box 3 through the gap between the first connecting block 10 and the control box 3, and under the action of the limit rod 6, the slider 7 can only move in the horizontal direction.

[0038] The working principle of the utility model is as follows: under the action of the activated carbon filter 9, the gas entering the control box 3 can be filtered, and the dust in the smoke in the air can be filtered before entering the control box 3, so as to keep the control box 3 clean and tidy, and prevent the dust in the smoke from entering the control box 3 through the heat dissipation port 4, thereby preventing the dust from adhering to the electrical components in the control box 3. After the activated carbon filter 9 has been used for a period of time, the first connecting block 10 is pulled upward, so that the movable first connecting block 10 drives the second connecting block 15, the handle 11, the activated carbon filter 9 and the connecting ring 8 to move, so that the movable connecting ring 8 can drive the slider 7 to move horizontally on the limit rod 6, and at the same time, the moving slider 7 will squeeze the spring 12 on the positioning block 5, so that the spring 12 is in a taut state. When the moved activated carbon filter 9 is no longer in contact with the positioning block 5, the handle 11 is pulled, so that the second connecting block 15 and the activated carbon filter 9 can be removed from the docking groove 16 through the taking groove 17, thereby facilitating the removal of the activated carbon filter. 9 is cleaned to avoid excessive impurities adhering to the activated carbon filter 9 after long-term use, which may affect the filtering effect of the activated carbon filter 9. When the activated carbon filter 9 is removed, the first connecting block 10 is released, so that the spring 12 is no longer restricted by the tension and rebounds, so that the rebound spring 12 can drive the slider 7 and the connecting ring 8 to reset. After the activated carbon filter 9 is cleaned, the first connecting block 10 is pulled again to move the slider 7 and the connecting ring 8 while keeping the spring 12 in a taut state, and then the second connecting block 15 and the activated carbon filter 9 are inserted into the docking groove 16, and the first connecting block 10 is released, so that the spring 12 is no longer restricted by the tension and rebounds, so that the rebound spring 12 drives the slider 7, the connecting ring 8, the activated carbon filter 9, the first connecting block 10, the handle 11 and the second connecting block 15 to move. When the moved activated carbon filter 9 enters the slide groove 14, the restriction on the activated carbon filter 9 is realized to prevent the activated carbon filter 9 from being separated from the docking groove 16.
