Description

Technical Field

[0001] The invention belongs to the technical field of online temperature measuring devices for vertical flues of coke ovens, and particularly relates to a temperature measuring instrument mounting seat. Background Art

[0002] Online temperature measurement of the vertical fire channel of the coke oven is a necessary condition for the intelligence and automation of temperature control of the coke oven. The online temperature measurement device needs to be installed at the original manual temperature measurement position. The fire viewing hole seat and fire viewing hole cover at the original manual temperature measurement position are designed and manufactured for manual temperature measurement. There are many problems in simply fixing the temperature measurement device on the original fire viewing hole cover.

[0003] In the prior art, the temperature measurement of the vertical fire channel of the coke oven needs to install a thermometer or an optical device at the vertical fire channel position close to the coal loading car track. According to statistics, there are two installation positions: one is that the vertical fire channel is embedded in the track seat plate, and the other is located next to the track. At the same time, the sizes of the vertical fire channels of various manufacturers are different, some are large and some are small. But in any case, the upper mouth of the original vertical fire channel is composed of a fire viewing hole seat and a fire viewing hole cover, that is, the fire viewing hole seat is bonded to the upper mouth of the vertical fire channel, and the fire viewing hole cover is placed on the fire viewing hole seat and sealed by the conical surface. In the past, for manual temperature measurement, workers needed to hook up the fire viewing hole cover with a hook, measure the temperature of the triangular area at the bottom of the vertical fire channel from the inner hole of the fire viewing hole seat with a handheld thermometer, and then cover the cover; when installing an online thermometer, the thermometer (or optical lens) is fixed on a mounting seat (i.e., furnace cover) that is consistent with the size of the fire viewing hole cover, and then the mounting seat is welded to the fire viewing hole seat.

[0004] The prior art has the following disadvantages:

[0005] 1. Before the mounting base is fixed, the center of the optical lens has been aligned with the triangular area at the bottom of the vertical fire channel, and then welded and fixed. After a period of use, the fire hole seat and the furnace body are deformed, and the optical center deviates from the triangular area at the bottom of the vertical fire channel. After the optical center deviates, the temperature measurement accuracy decreases, but it cannot be adjusted because it is fixed by welding;

[0006] 2. If the position needs to be adjusted, just grind the welding point, realign it and weld it in place;

[0007] 3. Using electric welding machines on coke ovens requires a fire permit, which is complicated and costly to operate;

[0008] 4. The fire hole seat and the fire hole cover are connected by a cone surface. The fire hole seat does not move during installation. The position of the fire hole cover should be adjusted so that the optical device is aligned with the triangular area. The cone surface of the fire hole cover cannot fit with the cone surface of the fire hole seat. There is no complete sealing line between the cone surfaces. Once it rains, water will penetrate into the vertical fire channel from the gap, generating water vapor that affects the temperature measurement.

[0009] 5. The fire viewing hole seat is installed at the top of the vertical fire channel, where the temperature is extremely high (reaching over 600 degrees Celsius). The fire viewing hole cover is in direct contact with the fire viewing hole seat, and the heat is directly conducted. The temperature of the fire viewing hole cover is also extremely high (over 300 degrees Celsius). In this way, the optical devices are in a high temperature environment. Optical devices cannot withstand high ambient temperatures for a long time. The introduced purge air, on the one hand, forms a slight positive pressure in front of the optical lens to prevent dust from adhering to the lens, and the other main purpose is to cool the lens. However, in the actual working environment, although the probability of gas cut-off is very small, it always exists, and when the gas is cut off, the optical lens will melt. Summary of the invention

[0010] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a temperature measuring instrument mounting base with a modular structure and an adjustable pitch angle of the mounting plate.

[0011] In order to solve the technical problem, the technical solution of the present invention is: a thermometer mounting base, including a purge pipe assembly, a mounting disk assembly, an air pipe and a fire viewing hole plug assembly, the purge pipe assembly includes a sleeved inner tube and an outer tube, the mounting disk assembly is provided with a through hole along its radial direction, one end of the outer tube is embedded in the through hole, one end of the air pipe passes through the mounting disk assembly and is connected to the outer tube, and the fire viewing hole plug assembly is sleeved on the outside of one end of the outer tube close to the mounting disk assembly.

[0012] Preferably, the mounting disk assembly includes an upper plate, a lower plate, a first thermal insulation block, a plurality of connecting plates and a plurality of adjusting parts, the first thermal insulation block is installed between the upper plate and the lower plate, one end of the connecting plate is connected to the upper plate and the other end thereof is connected to the lower plate, the adjusting part passes through the upper plate, the first thermal insulation block and the lower plate and contacts with the glow plug assembly, there is a gap between the mounting disk assembly and the glow plug assembly, and the relative position of the mounting disk assembly and the glow plug assembly can be adjusted by turning the adjusting part.

[0013] Preferably, the fire-viewing hole plug assembly comprises a mounting plate, a second heat-insulating block and a baffle, wherein the second heat-insulating block is mounted between the mounting plate and the baffle, wherein the mounting plate is sleeved on one end of the outer tube close to the mounting plate assembly.

[0014] Preferably, it also includes a bottom plate, which is sleeved on the outside of the second insulation block and is located below the mounting plate, and the mounting plate is mounted on the bottom plate by screws.

[0015] Preferably, the diameter of the inner tube is smaller than the diameter of the outer tube and the inner tube is located at one end of the outer tube close to the lower plate, and the end of the outer tube close to the lower plate is embedded in the through hole of the lower plate.

[0016] Preferably, it also includes a plugging piece installed on one end of the outer tube close to the inner tube, a gap is formed between the inner tube and the outer tube of the set, and a cavity with one end closed is formed between the plugging piece, the inner tube and the outer tube.

[0017] Preferably, it further comprises a threaded sleeve mounted on the upper plate, and the adjusting member comprises a screw and a nut, the screw is screwed into the threaded sleeve and is locked on the upper plate by the nut.

[0018] Preferably, the number of the multiple connecting plates and the multiple adjusting members is three, and the three connecting plates and the three adjusting members are evenly arranged along the circumference of the upper plate.

[0019] Preferably, it further comprises a plurality of baffles arranged under the baffle plate, wherein the plurality of baffles are arranged radially.

[0020] Preferably, the outer side of the second insulation block is wrapped with a soft insulation material coated with refractory glue.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) The present invention adopts a modular structure, which works together to achieve the requirements of thermal insulation, adjustment, stability, etc., and is relatively convenient for installation and maintenance;

[0023] (2) During installation, the fire-viewing hole plug assembly of the present invention is fixed to the furnace body as a whole, the purge pipe assembly is welded to the fire-viewing hole plug assembly, and the lower plate of the mounting plate assembly is connected to the mounting plate through an outer tube, which has low rigidity. Therefore, the pitch angle of the mounting seat assembly can be adjusted by three screws;

[0024] (3) In the purge pipe assembly of the present invention, the inner pipe, the outer pipe and the plugging plate form a downward annular gap. After the purge gas from the air pipe enters the narrow gap, it can only enter the vertical fire channel downward. This structure can prevent the external gas from moving upward, and the moisture, dust and the like carried in the air from contacting the instrument on the mounting seat. The air blown out from the air pipe encounters the obstruction of the inner pipe, and the distribution on both sides is not balanced, generating a rotation force. Therefore, the airflow blown downward enters the vertical fire channel in a spiral shape. After the airflow breaks away from the obstruction of the inner pipe downward, the inner pipe obstructs it. The spiral air forms a micro vacuum near the axis of the inner cavity of the inner pipe. Therefore, the dust and the like accumulated in the upper channel will be subjected to a downward force and tend to fall off downward.

[0025] (4) In the present invention, the glow plug assembly is fixed to the base plate by screws through the mounting plate, and the heat transmitted by the glow plug assembly is further dissipated by the base plate, and the temperature of the base plate is reduced to below 120 degrees.

[0026] (5) The mounting plate assembly of the present invention has the same structure as the glow plug assembly. The upper plate and the lower plate form a framework through the connecting plate, and the first heat insulation block is filled in the middle. The principle is the same as that of the glow plug assembly. The direct heat conduction is only through the connecting plate and the screw path. In this way, the contact surface temperature of the instrument fixed on the mounting plate assembly can be reduced to below 70 degrees.

[0027] (6) In the present invention, a plurality of baffles are welded to the bottom plate of the spark plug. When the asbestos rope and glue wound on the second insulation block in the spark plug assembly have not solidified, the baffles are bent upward to bear the weight of the asbestos rope and glue and prevent them from falling into the vertical fire channel.

[0040] The specific implementation mode of the present invention is described below in conjunction with embodiments:

[0041] It should be noted that the structures, proportions, sizes, etc. shown in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0042] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0043] like Figure 1-6 As shown, a thermometer mounting seat includes a purge pipe assembly 1, a mounting plate assembly 2, an air pipe 3 and a fire hole plug assembly 4, the purge pipe assembly 1 includes a set of inner tube 1-1 and outer tube 1-2, that is, a double-layer tube is formed, the diameter of the inner tube 1-1 is smaller than the diameter of the outer tube 1-2 and the inner tube 1-1 is located at one end of the outer tube 1-2 close to the lower plate 2-2, and also includes a plug installed on the outer tube 1-2 close to one end of the inner tube 1-1, a gap is formed between the set inner tube 1-1 and the outer tube 1-2, and a cavity with one end closed is formed between the plug 1-3, the inner tube 1-1 and the outer tube 1-2. The inner tube 1-1, the outer tube 1-2 and the plug 1-3 form a downward annular gap. The purge air from the air pipe 3 can only enter the vertical fire channel downward after entering the narrow gap. This structure can prevent the external gas from moving upward, and the moisture, dust, etc. carried in the air will contact the instruments on the mounting base. The air blown out from the air pipe 3 is blocked by the inner tube 1-1, and the distribution on both sides is not balanced, which generates a rotational force. Therefore, the airflow blown downward enters the vertical fire channel in a spiral shape. After it is not blocked by the inner tube 1-1, the spiral air forms a micro vacuum near the central axis of the purge pipe assembly 1. Therefore, the dust, etc. accumulated in the upper channel will be subjected to a downward force and tend to fall off downward.

[0044] The mounting plate assembly 2 includes an upper plate 2-1, a lower plate 2-2, a first thermal insulation block 2-3, a plurality of connecting plates 2-4 and a plurality of adjusting members 2-5, the first thermal insulation block 2-3 being installed between the upper plate 2-1 and the lower plate 2-2, one end of the connecting plate 2-4 being connected to the upper plate 2-1 and the other end thereof being connected to the lower plate 2-2, the adjusting member 2-5 passing through the upper plate 2-1, the first thermal insulation block 2-3 and the lower plate 2-2 and contacting the fire plug assembly 4.

[0045] The fire-watching hole plug assembly 4 includes a mounting plate 4-1, a second heat-insulating block 4-2 and a baffle 4-3, wherein the second heat-insulating block 4-2 is mounted between the mounting plate 4-1 and the baffle 4-3, wherein the mounting plate 4-1 is sleeved on one end of the outer tube 1-2 near the mounting plate assembly 2. The fire-watching hole plug assembly 4 is fixed to the seat plate 7 by screws through the mounting plate 4-1, and the heat transmitted by the fire-watching plug is further dissipated by the seat plate 7, and the temperature of the seat plate 7 is reduced to below 120 degrees. In addition, a heat-insulating soft material coated with refractory glue is wound around the outside of the second heat-insulating block 4-2. The second heat-insulating block 4-2 blocks the passage between the vertical fire channel and the furnace surface, and while blocking the rising of the high-temperature air in the lower part, its own thermal conductivity is very small, which effectively isolates the heat transfer upward from the vertical fire channel. The outer tube 1-2 with a higher thermal conductivity coefficient plays the role of the skeleton of the fire-watching hole plug, and the heat transfer of the side wall is limited. This structure basically isolates the high temperature inside the vertical fire channel from the outside world, and the actual measurement is less than 200 degrees.

[0046] There is a gap between the mounting plate assembly 2 and the glow plug assembly 4. The relative position of the mounting plate assembly 2 and the glow plug assembly 4 can be adjusted by turning the adjusting member 2-5, that is, the pitch angle of the mounting seat assembly 2 relative to the mounting plate 4-1 can be adjusted. The adjusting member 2-5 also includes a screw sleeve 5 installed on the upper plate 2-1. The adjusting member 2-5 includes a screw and a nut. The screw is screwed into the screw sleeve and locked on the upper plate 2-1 through the nut.

[0047] The upper plate 2-1 is also provided with a mounting hole 8 for an external instrument.

[0048] The mounting plate assembly 2 is provided with through holes along its radial direction, wherein one end of the outer tube 1-2 close to the lower plate 2-2 is embedded in the through hole of the lower plate 2-2, that is, the outer tube 1-2 and the lower plate 2-2 are welded as one body, one end of the air pipe 3 passes through the mounting plate assembly 2 and is connected to the outer tube 1-2, and the air pipe 3 is welded as one body to the outer tube 1-2 in the purge pipe assembly through the hole reserved in the first heat insulation block 2-3. The fire-watching hole plug assembly 4 is sleeved on the outer side of one end of the outer tube 1-2 close to the mounting plate assembly 2.

[0049] A plurality of baffles 6 are arranged under the baffle 4-3, and the plurality of baffles 6 are arranged radially and can be bent. The function of the baffles is to intercept the heat-insulating soft material coated with refractory glue. Among them, the number of the plurality of connecting plates 2-4 and the plurality of adjusting parts 2-5 is three, and the three connecting plates 2-4 and the three adjusting parts 2-5 are evenly arranged along the circumference of the upper plate 2-1.

[0050] Working principle:

[0051] During installation, first remove the original fire viewing hole seat and fire viewing hole cover, and clean the area around the hole. If the furnace surface bricks are shaking, they should be removed and cleaned to create an installation surface larger than the seat plate 7. The installation surface should be firm and reliable.

[0052] After the mounting seat assembly 2 is connected to the seat plate 7 through the outer tube 1-2, a soft insulating material similar to asbestos rope is wrapped around the outside of the second insulating block 4-2 of the fire hole plug assembly, and refractory glue is applied on each layer. The outer diameter of the second insulating block 4-2 is thickened to the same as the outer diameter of the fire hole seat, and then the baffle 6 is bent upward to prevent the additional asbestos rope and glue from falling into the vertical fire channel.

[0053] After applying glue on the installation surface, insert the fire viewing hole plug assembly 4 into the fire viewing hole, and at the same time make the seat plate 7 close to the installation surface. When pressing the seat plate 7, ensure that the central axis of the purge pipe assembly 1 coincides with the center line of the vertical fire channel.

[0054] When the glue is dry, the base plate 7 and the fire-viewing hole plug are integrated with the furnace surface.

[0055] The pitch angle of the mounting plate assembly can be adjusted by screwing in or out the three screws on the mounting plate assembly 2. The pitch angle is determined by the gap between the lower plate 2-2 of the mounting plate assembly 1 and the mounting piece 4-1. The lower plate 2-2 of the mounting plate assembly is welded to the outer tube 1-2 of the purge pipe assembly 1 as a whole. The purge pipe assembly 1 is respectively welded to the mounting piece 4-1 and the baffle 4-3 of the fire hole plug assembly 4. The mounting plate assembly 2 realizes the change of pitch by elastic deformation.

[0056] The fire hole plug assembly 4 and the mounting plate assembly 2 are both a combination structure of stainless steel metal sheets and heat insulating materials, which prevents heat conduction to the greatest extent.

[0057] The seat plate 7 is relatively large in size and can be firmly bonded to the furnace surface, thereby improving the stability of the pyrometer after installation.

[0058] In summary, the heat conduction of the entire mounting plate structure has only three connecting plates 2-4 and three screw paths, so that the contact surface temperature of the instrument fixed on the mounting plate is reduced to below 70 degrees, the internal temperature of the vertical fire duct is isolated, the external surface temperature is completely reduced, and after installation, the vertical fire duct is completely isolated from the external space, and rainwater cannot penetrate into the interior of the vertical fire duct.

[0059] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
