Description

Technical Field

[0001] The invention relates to a device for eliminating leakage of methanol cracking gas from an isothermal quenching furnace. Background Art

[0002] Metal heat treatment is a metal heat treatment process that uses an isothermal quenching furnace to heat the metal workpiece to a certain appropriate temperature and maintain it for a period of time, and then immerses it in a quenching medium for rapid cooling. Common quenching media include salt water, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, gauges and parts that require surface wear resistance (such as gears, rollers, carburized parts, etc.). By combining quenching with tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different usage requirements.

[0003] The isothermal quenching furnace works in a pre-vacuum and atmosphere protection mode. During operation, the furnace is first evacuated to a certain vacuum degree and then a protective atmosphere (such as methanol protective atmosphere) is filled into the furnace for protective heating, so as to achieve the purpose of less oxidation heating or non-oxidation heating of the workpiece in the protective atmosphere. The addition of protective atmosphere plays a very important role. In the metal heat treatment process, methanol is one of the important auxiliary materials, but methanol is also a substance that is harmful to the human body. It will cause harm to the human body after accidental ingestion, and in severe cases it may also cause blindness and death (the minimum dose of oral poisoning for humans is about 100 mg / kg body weight, and oral ingestion of 0.3-1 g / kg can be fatal). Methanol, as a highly volatile liquid, can be inhaled into the body. The relative vapor density of liquid methanol after gasification (air = 1): 1.1, which is greater than the air density.

[0004] At present, a structure used in a quenching process includes: an isothermal quenching furnace body, a methanol gasification device, a pipeline connecting the top of the body and the gasification device, a manually operated valve for controlling the opening and closing of the pipeline is provided near the top of the body on the pipeline, and conventional flange connections are used between the pipelines in the pipeline; the quenching process is: liquid methanol is first gasified and cracked in the gasification device, and then the methanol is jet-added into the quenching furnace through the pipeline for use.

[0005] The above-mentioned structural form and corresponding quenching process have the following defects: liquid methanol has been completely cracked before entering the quenching furnace, and the methanol that has been gasified and cracked is transported by means of pipelines. Conventional flange connections are used between the pipelines in the pipeline. There are many connection nodes. The flange connection is very inconvenient during disassembly and replacement, and the sealing cannot be guaranteed. The valve is close to the top of the body and has a high height. In this way, methanol is easy to leak before entering the quenching furnace. In addition, the operators are immersed in their own work and the production workshop is large and empty. The leakage of methanol gas is difficult to detect, handle and eliminate in time. The leaked methanol gas will pollute the enterprise and the surrounding atmosphere, causing certain physical injuries to the operators and surrounding personnel, leading to the occurrence of safety accidents; in addition, the manual opening and closing operation of the valve is also very inconvenient.

[0006] In addition, now, in order to better carry out the teaching activities of relevant courses, some colleges and universities will use the classrooms in the school teaching buildings and set up isothermal quenching furnaces and other equipment in the classrooms as school laboratories for relevant courses. However, due to various factors, schools generally fail to equip the corresponding methanol cracking gas leakage elimination devices at the same time.

[0007] As we all know, colleges and universities have a large number of teachers and students and are densely populated. The distance between adjacent teaching buildings on campus is relatively narrow, the height of each floor is low, and the ventilation conditions are poor.

[0008] When teachers and students use an isothermal quenching furnace and fill the furnace with a methanol protective atmosphere to conduct teaching experiments and heat workpieces (such as binder clips, etc.), as mentioned above, methanol is prone to leak before entering the quenching furnace. The leaked methanol gas will pollute the campus and the surrounding atmosphere, causing certain physical injuries to teachers, students and surrounding personnel, and leading to safety accidents. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a leakage elimination device for methanol cracking gas in an isothermal quenching furnace. By adopting the elimination device, the leakage of methanol gas can be detected. When the concentration of methanol gas leaked into the air around the main body exceeds the set safety value, an audible and visual prompt can be given, and a valve working synchronously with the audible and visual prompt can automatically close the gasification device, thereby effectively avoiding the occurrence of safety accidents.

[0013] The shell of the controller is in the shape of a hollow cuboid, the upper parts of the front side and rear side of the shell are in the shape of a semi-ellipse, and the rear side of the shell is a vertical plane. It is set as follows: the upper part of the front side of the shell is the first surface, and the lower part of the front side of the shell includes the second surface, the third surface, and the fourth surface which are arranged vertically on the left and right and smoothly connected. The first surface, the second surface, and the fourth surface are in the same vertical plane and are far away from the rear side of the shell. The third surface is close to the rear side of the shell. The first surface and the third surface are smoothly connected up and down. The first surface is provided with a plurality of long strip-shaped pronunciation holes, and the third surface is provided with a plurality of long strip-shaped pronunciation holes. A plurality of circular first air inlet holes are arranged on the second surface, a plurality of circular second air inlet holes are arranged on the fourth surface, a plurality of circular third air inlet holes and fourth air inlet holes are arranged on the rear side surface of the shell at positions corresponding to the first air inlet holes and the second air inlet holes, a display screen is arranged on one side of the third surface in the length direction, a power light and a prompt light are arranged at intervals in the middle of the third surface in the length direction, a first mark and a second mark are arranged at intervals in the upper and lower parts on the other side of the third surface in the length direction, the power light and the first mark correspond in position, and the prompt light and the second mark correspond in position;

[0014] The upper part of the shell is provided with a speaker and a power module arranged at intervals in front and back, and the speaker corresponds to the sound hole in position. The lower part of the shell is provided with a single-chip microcomputer and a gas detector arranged at intervals in front and back. The power line of the power module passes through the upper side of the shell and is wound around the wire storage wheel at one corresponding end in the length direction of the frame. The connection line between the valve and the single-chip microcomputer passes through the upper side of the shell and is wound around the wire storage wheel at the other corresponding end in the length direction of the frame.

[0015] The gas detector, the speaker, the display screen, the prompt light, and the valve are connected to the single-chip microcomputer, and the power module is connected to the gas detector and the single-chip microcomputer respectively.

[0016] In order to explain the problem concisely and clearly, the isothermal quenching furnace methanol cracking gas leakage elimination device described in the present invention is referred to as the elimination device below.

[0017] The working principle and advantages of this exclusion device:

[0018] When working, the single chip microcomputer controls the gas detector to work, and the gas detector can detect the leakage of methanol gas before entering the main body; when methanol leaks on the pipeline and the concentration of methanol gas leaked into the air around the main body exceeds the set safety value, the gas detector will send a signal to the single chip microcomputer. After receiving the signal sent by the gas detector, the single chip microcomputer sends signals to the horn, the warning light, and the valve respectively. The horn, the warning light, and the valve start working immediately after receiving the signal sent by the single chip microcomputer: the horn uses sound and the warning light uses light to remind the operating personnel of the production enterprise: methanol gas leakage has occurred around the main body, and the operating personnel are requested to take corresponding measures immediately (such as inspection or personnel evacuation); the valve located on the pipeline and close to the gasification device will automatically close, cut off the gasification device (ie: gas source), prevent further leakage of methanol gas, eliminate safety hazards, and effectively avoid the occurrence of safety accidents. In this way, the leakage of methanol gas can be easily discovered, handled and eliminated in time, and the air around the production enterprise will not be polluted, ensuring the personal safety of the operating personnel.

[0019] in addition,

[0020] The setting of the frame and the running wheels facilitates the controller (including the housing, display screen, power light, prompt light, horn, power module, single chip microcomputer, gas detector) to move back and forth along the length direction of the body, and realizes multi-position detection of the methanol gas concentration leaked into the air around the body, thereby improving the timeliness and speed of detection;

[0021] The two wire storage columns and two wire storage wheels are set up to store the power wires and connecting wires accordingly. When the frame moves back and forth along the length direction of the body, the power wires and connecting wires can be collected and released accordingly without affecting the normal operation of the power module and valve;

[0022] The upper parts of the front side and rear side of the shell are in a semi-elliptical shape, the first surface and the third surface are smoothly connected up and down, and the second surface, the third surface, and the fourth surface are smoothly connected. In this way, the upper side and the middle area of ​​the shell in the length direction have no sharp angles and are smooth and beautiful, avoiding personal injury due to carelessness during use;

[0023] The first surface, the second surface, and the fourth surface are in the same vertical plane and are far away from the rear side surface of the shell, and the third surface is close to the rear side surface of the shell, so that the third surface is concave, and the display screen, power light, and prompt light installed on the third surface are lower than the first surface, the second surface, and the fourth surface, so as to avoid damage to the display screen, power light, and prompt light due to bumps;

[0024] The speaker on the front side of the upper part of the shell corresponds to the sound hole on the first surface in position, so that the speaker can produce clear sound and the sound propagation speed is fast;

[0025] The setting of the display screen enables the detection concentration of the leaked methanol gas to be digitally displayed, which is more intuitive;

[0026] The power light is set to intuitively indicate the working status of the power module;

[0027] The setting of the first mark and the second mark enables the operator to accurately know the corresponding functions and working states of the power light and the prompt light;

[0028] The arrangement of the first and second air inlet holes at the lower front side of the shell, and the arrangement of the corresponding third and fourth air inlet holes at the lower rear side of the shell, allow the air around the body and / or leaked methanol gas to enter the shell in a front-to-rear convection manner, which can be easily detected by the gas detector.

[0029] In summary, the exclusion device can be used to detect the leakage of methanol gas. When the concentration of methanol gas leaked into the air around the main body exceeds the set safety value, it can give sound and light prompts, and the valve working synchronously with the sound and light prompts will automatically close the gasification device, effectively avoiding the occurrence of safety accidents.

[0030] A rotating handle parallel to the axis of the wire storage wheel is provided at the outer edge of the front side of each wire storage wheel;

[0031] Two drawers spaced apart from each other are arranged in the length direction of the frame, a circular, concave pulling hole is arranged in the middle of each drawer, and a handle is arranged at the end of the frame close to the display screen in the length direction.

[0032] The setting of the rotating handle facilitates the rotation of the corresponding wire storage wheel, so that the power cord and the connecting wire can be collected and released more smoothly; the setting of the handle facilitates the pushing of the frame; the setting of the two drawers facilitates the storage of tools, etc.

[0033] There are seven pronunciation holes, of which four are arranged in an isosceles trapezoid, and the other three are arranged in the isosceles trapezoid and spaced apart from each other in a straight line.

[0034] The second surface is provided with two first cylindrical bodies which are coaxially arranged inside and outside and open at the front and rear ends, and there are nine first air inlet holes, of which: eight first air inlet holes are evenly distributed between the two first cylindrical bodies in the circumferential direction, and another first air inlet hole is located inside the inner first cylindrical body and the two are coaxial;

[0035] The fourth surface is provided with two second cylindrical bodies arranged coaxially inside and outside and open at the front and rear ends, and there are nine second air inlet holes, of which: eight second air inlet holes are evenly distributed between the two second cylindrical bodies in the circumferential direction, and another second air inlet hole is located in the inner second cylindrical body and the two are coaxial;

[0036] Two third cylinders are arranged coaxially inside and outside and open at the front and rear ends on the left side of the rear side of the shell, and there are nine third air inlet holes, of which eight third air inlet holes are evenly distributed between the two third cylinders in the circumferential direction, and the other third air inlet hole is located in the inner third cylinder and the two are coaxial;

[0037] Two fourth cylinders are arranged coaxially inside and outside and open at the front and rear ends on the right side of the rear side of the shell, and there are nine fourth air inlet holes, of which eight fourth air inlet holes are evenly distributed between the two fourth cylinders in the circumferential direction, and the other fourth air inlet hole is located inside the inner fourth cylinder and the two are coaxial.

[0038] The two first cylindrical bodies, the two second cylindrical bodies, the two third cylindrical bodies, and the two fourth cylindrical bodies have the same specifications, and the nine first air inlet holes, the nine second air inlet holes, the nine third air inlet holes, and the nine fourth air inlet holes have the same specifications;

[0040] The single chip microcomputer is located in the middle of the lower part of the shell in the length direction, and the single chip microcomputer is seated on the lower side of the shell;

[0041] The gas detector is connected to the rear side of the shell. The gas detector is in the shape of a rectangular parallelepiped. The two ends of the gas detector in the length direction correspond to the left and right sides close to the shell. It is set that: the area of ​​the left side portion of the gas detector corresponding to the nine first air inlet holes in position is S1, the area of ​​the right side portion of the gas detector corresponding to the nine second air inlet holes in position is S2, the area enclosed by the nine first air inlet holes is S3, and the area enclosed by the nine second air inlet holes is S4, then: S1 is equal to S2, S3 is equal to S4, S1 is less than S3, and S2 is less than S4.

[0042] The seven pronunciation holes are arranged in a combination of isosceles trapezoid and straight line, so that the pronunciation holes are arranged compactly and reasonably on the first surface;

[0043] The above arrangement of the two first cylinders and the nine first air inlet holes, the two second cylinders and the nine second air inlet holes, the two third cylinders and the nine third air inlet holes, and the two fourth cylinders and the nine fourth air inlet holes enables the front and rear sides of the shell to be symmetrically provided with four groups of cylinders and four groups of air inlet holes, and each group of cylinders serves as an air induction channel, so that the air around the body and / or the leaked methanol gas can be smoothly, quickly, and front-to-back convection drawn into the shell through any two groups of cylinders and corresponding air inlet holes that are symmetrical front and back;

[0044] The position and length of the gas detector, as well as the area of ​​any side of the length direction of the gas detector, are smaller than the area enclosed by the nine first air inlet holes (or the area enclosed by the nine second air inlet holes), so that the air drawn into the shell and / or the leaked methanol gas will be blown directly onto the gas detector, allowing the gas detector to fully contact the air entering the shell and / or the leaked methanol gas, thereby achieving rapid detection.

[0045] The pipeline includes a first pipe connected to the gasification device and a second pipe connected to the body, and the valve is located in the first pipe;

[0047] A plurality of guide blocks extending axially and corresponding to the plurality of guide grooves are uniformly distributed along the circumferential direction on the inner wall of the end of the second tube away from the body; two second ear plates symmetrical to each other and corresponding to the two first ear plates in position are arranged circumferentially on the outer side of the end of the second tube away from the body; the axial distance between the second ear plate and the end of the second tube away from the body is greater than the axial length of the guide block; a bearing corresponding to and coaxial with the corresponding first threaded hole in position is arranged on each second ear plate; a positioning tube corresponding to and coaxial with the corresponding bearing in position is arranged on the side of each second ear plate away from the guide block; and two positioning holes communicating with each other up and down and coaxial are arranged in the circumference of the positioning tube;

[0048] The end of the second tube away from the body is inserted into the annular recess, and the guide block is inserted into the guide groove. A tightening rod is provided between the first ear plate and the second ear plate corresponding to each other. One side of the tightening rod is screwed into the first threaded hole and screwed to the first ear plate, and the other side of the tightening rod passes through the bearing and the positioning tube and is connected to the second ear plate. A hand wheel is provided at the other end of the tightening rod, and the end of the second tube away from the body is in close contact with the sealing gasket. A positioning pin is provided between the positioning tube and the other side of the tightening rod, and the positioning pin passes through the positioning hole on the upper side, the other side of the tightening rod and the positioning hole on the lower side in sequence, so that the first tube and the second tube are connected.

[0049] The above-mentioned structural form allows the first pipe and the second pipe to be sealed and connected by plugging and tightening, and the tightening rod is positioned circumferentially and axially. In this way, the sealing of the pipeline is guaranteed, and the methanol cracking gas can be transported safely and without leakage.
