Description

Technical Field

[0001] The present invention relates to the technical field of thermal cycling, and more particularly to an industrial production thermal cycling device. Background Art

[0002] An industrial production thermal cycling device is an equipment system used to effectively utilize heat energy during the industrial production process. The core principle is that through the cyclic flow of a medium such as water or heat transfer oil, heat is transferred from a heat source to places that require heat, such as reaction kettles, dryers, etc. And after the heat is released, the medium returns to the heat source to re-absorb heat, and so on in a cycle, so as to achieve the purpose of energy conservation and stable heat supply. For some small thermal cycling devices with high requirements for temperature control accuracy or not suitable for obtaining heat by combustion, electric heating elements are the heat source.

[0003] During the specific use process, due to the long-term use of electronic components, high temperature will inevitably have a certain impact on the heating components, thus bringing a certain possibility of failure. If shutdown detection is carried out, it will delay the production efficiency. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides an industrial production thermal cycling device that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An industrial production thermal cycling device includes a chassis. A structural frame is provided inside the chassis. A circulation switching mechanism is provided on the structural frame. The circulation switching mechanism includes:

[0007] A first mounting frame located at the bottom of the side of the structural frame;

[0008] A second mounting frame located at the top of the side of the structural frame. Vertical shafts are provided around the bottom of the second mounting frame. A vertical rod is provided on one side of the bottom of the second mounting frame. A second limiting shaft is movably provided on one side of the bottom of the vertical rod. A first pulley and a second pulley are movably provided on the shaft body of the second limiting shaft;

[0010] By setting up a cyclic switching mechanism, the first mounting frame and the second mounting frame of the cyclic switching mechanism can exchange positions with each other. When one of them fails, the heating components such as the heating mesh in the other mounting frame can be replaced to the original position to continue working. At the same time, the damaged heating mesh can be replaced and repaired, realizing maintenance without shutting down the machine. In industrial production, shutting down the equipment for maintenance often leads to the interruption of the production process, causing huge economic losses. By realizing maintenance without shutting down the machine through the cyclic switching mechanism, it can ensure the continuous progress of the production process. Maintenance without shutting down the machine allows enterprises to arrange maintenance work more flexibly when the equipment is operating normally. There is no need to urgently deploy maintenance personnel and spare parts for rush repair of faulty equipment, nor is it necessary to pay the additional costs caused by shutdown. In one embodiment of the present invention, the...

[0011] In one embodiment of the present invention, an air inlet grille is provided at the bottom of one side of the chassis, and an air outlet grille is provided at the top of the other side of the chassis.

[0012] By setting up a cyclic switching mechanism, the first mounting frame and the second mounting frame of the cyclic switching mechanism can exchange positions with each other. When it is necessary to replace the heating temperature in a timely manner, the heating mesh that is not in the ventilation position can be preheated to the required temperature in advance, and then the heating components such as the heating mesh in the other mounting frame can be replaced to the original position, so as to achieve the purpose of immediately replacing the heat circulation temperature without waiting for the change of the temperature of the inherent heating mesh. In industrial production, many technological processes have high requirements for the response speed of temperature changes. For example, in chemical synthesis reactions, different reaction stages may require different temperature conditions. By this way of quickly replacing the heat circulation temperature, rapid temperature conversion can be achieved between different reaction stages without waiting for the original heating mesh to heat up or cool down, greatly shortening the time for process adjustment, making the entire production process more compact and efficient, and improving production efficiency.

[0013] In one embodiment of the present invention, a first heating mesh is provided inside the frame body of the first mounting frame, and a second heating mesh is provided inside the frame body of the second mounting frame.

[0014] In one embodiment of the present invention, first slide rails located on the structural frame are provided at the bottoms of both sides of the first mounting frame.

[0018] In one embodiment of the present invention, a bottom mounting bracket is provided at the bottom of the structural frame.

The first pulley and the second pulley are both located in the special-shaped grooves. Second slide rails are provided at both bottom sides of the sliding frame, and the second slide rails are arranged at the top of the opposite sides of the second special-shaped grooved plate.

[0019] In one embodiment of the present invention, a blower is arranged on the structural frame through a mounting bracket. The blower is located between the second threaded shaft and the first mounting frame, and the blower is flush with the air outlet grille in height.

[0020] In one embodiment of the present invention, a heightening frame located at the bottom of the inner wall of the chassis is provided at the bottom of the structural frame. Limit rings are provided around the top of the sliding frame, and the limit rings are sleeved on the shaft body of the vertical shaft.

[0021] An industrial production heat circulation device provided by the present invention has the following beneficial effects:

[0022] 1. By setting a circulation switching mechanism, the first mounting frame and the second mounting frame of the circulation switching mechanism can exchange positions with each other. When one of them fails, the heating components such as the heating mesh in the other mounting frame can be replaced to the original position to continue working. At the same time, the damaged heating mesh can be replaced and repaired, realizing maintenance without stopping the machine.

Maintenance without stopping the machine allows enterprises to arrange maintenance work more flexibly when the equipment is running normally.

[0023] 2. By setting a circulation switching mechanism, the first mounting frame and the second mounting frame of the circulation switching mechanism can exchange positions with each other. When it is necessary to change the heating temperature in time, the heating mesh that is not in the ventilation position can be preheated to the required temperature in advance, and then the heating components such as the heating mesh in the other mounting frame can be replaced to the original position, so as to achieve the purpose of immediately changing the heat circulation temperature without waiting for the change of the temperature of the inherent heating mesh. In industrial production, the response speed of many technological processes to temperature changes is very high.

[0024] 3. By setting up a cyclic switching mechanism, another air outlet grille can be additionally set at the intermediate position of the movement of the cyclic switching mechanism to achieve double-heating grille heating and the dual-mode cyclic effect of heat circulation. In industrial production, sometimes a higher heating power is required to meet specific production needs. The double-heating grille heating mode is equivalent to doubling the heating source, which can provide a larger amount of heat in a short time. The dual-mode cycle can work with two heating grilles simultaneously to accelerate the heating rate, thereby improving the efficiency of the entire production process.

Then, after the second limiting shaft 2091 re-enters the high groove of the special-shaped groove 305, while the entire second mounting frame 202 moves, it first moves downward and then upward in the vertical direction to make way for the moving first mounting frame 201.

[0039] Please refer to Figure 1-8 , an air inlet grid 101 is provided at the bottom of one side of the chassis 1, and an air outlet grid 102 is provided at the top of the other side of the chassis 1.

[0040] Please refer to Figure 1-8, a first heating grid 2011 is provided inside the frame of the first mounting frame 201, and a second heating grid 2021 is provided inside the frame of the second mounting frame 202. By providing a circulation switching mechanism 2, the first mounting frame 201 and the second mounting frame 202 of the circulation switching mechanism 2 can exchange positions with each other. When it is necessary to change the heating temperature in a timely manner, the heating grid that is not in the ventilation position can be preheated to the required temperature in advance, and then the heating components such as the heating grid in the other mounting frame can be replaced to the original position, so as to achieve the purpose of immediately changing the hot circulation temperature without waiting for the change of the temperature of the inherent heating grid. In industrial production, many process procedures have high requirements for the response speed of temperature changes. For example, in chemical synthesis reactions, different reaction stages may require different temperature conditions. It is possible to achieve rapid temperature conversion between different reaction stages without waiting for the original heating grid to heat up or cool down, which greatly shortens the time for process adjustment, makes the entire production process more compact and efficient, and improves production efficiency.

[0041] Please refer to Figure 1-8 , at the bottom of both sides of the first mounting frame 201, there are first slide rails 203 located on the structural frame 3. A perforated slider 204 is fixedly provided on one side of the first mounting frame 201, and a threaded slider 205 is provided on the other side of the first mounting frame 201. The threaded plate 211 moves back and forth, thereby moving the sliding frame 208 back and forth. The sliding frame 208 moves the vertical shaft 2082 back and forth, causing the second mounting frame 202 to also move back and forth. When the second mounting frame 202 moves back and forth, the vertical rod 209 will also move.

[0042] Please refer to Figure 1-8 , a first limiting shaft 207 is movably sleeved in the opening of the perforated slider 204, and a first threaded shaft 206 is provided in the threaded hole of the threaded slider 205. Open-ended straight plates 2071 are provided at both ends of the first limiting shaft 207 and one end of the first threaded shaft 206. The bottom end of the open-ended straight plate 2071 is connected to the frame of the structural frame 3.

[0043] Please refer to Figure 1-8 , the other end of the first threaded shaft 206 is provided with a first servo motor 5. The first servo motor 5 is provided on the frame of the structural frame 3. By driving the first servo motor 5, under the action of the first threaded shaft 206, the threaded slider 205 slides back and forth, causing the first mounting frame 201 to slide back and forth, and adjusting the position of the first heating grid 2011.

[0044] Please refer to Figure 1-8, a second servo motor 6 is provided at one end of the shaft body of the second threaded shaft 212. The second servo motor 6 is arranged on the structural frame 3 through a mounting bracket. By providing the circulation switching mechanism 2, another air outlet grille 102 can be additionally arranged at the intermediate position of the movement of the circulation switching mechanism 2 to achieve double heating grid heating and reach the dual-mode circulation effect of heat circulation. In industrial production, sometimes a higher heating power is required to meet specific production needs. The double heating grid heating mode is equivalent to doubling the heating source and can provide a larger amount of heat in a short time. For example, in the preheating stage of some large chemical reaction kettles or the initial stage of metal smelting, rapid temperature increase is required. The dual-mode circulation can work with two heating grids simultaneously to accelerate the heating rate and thus improve the efficiency of the entire production process.

[0045] Please refer to Figure 1-8 , a bottom mounting bracket 301 is provided at the bottom of the structural frame 3. At the midline of the top of the bottom mounting bracket 301, a first special-shaped slotted plate 303 is provided. Second moving slotted plates are provided on both sides of the top of the bottom mounting bracket 301. Special-shaped slots 305 are provided on both the first special-shaped slotted plate 303 and the second special-shaped slotted plate 304. Both the first pulley 2092 and the second pulley 2093 are located in the special-shaped slots 305. Second slide rails 210 are provided at both bottom sides of the sliding frame 208. The second slide rails 210 are arranged at the top of the opposite sides of the second special-shaped slotted plate 304. When the second mounting frame 202 moves back and forth, the vertical rod 209 also moves. When the first pulley 2092 and the second pulley 2093 of the vertical rod 209 move, when the vertical rod 209 enters the lowest slot of the special-shaped slot 305, the vertical rod 209 will pull the second mounting frame 202 downward, and the second mounting frame 202 moves downward while moving. Then, after the second limiting shaft 2091 re-enters the high slot of the special-shaped slot 305, while the entire second mounting frame 202 moves, it goes through a process of first moving downward and then rising in the vertical direction.

[0046] Please refer to Figure 1-8 , a blower 4 is arranged on the structural frame 3 through a mounting bracket. The blower 4 is located between the second threaded shaft 212 and the first mounting frame 201. The blower 4 is at the same height as the air outlet grille 102. Another air outlet grille 102 can be additionally arranged at the intermediate position of the movement of the circulation switching mechanism 2 to achieve double heating grid heating and reach the dual-mode circulation effect of heat circulation. The double heating grid heating mode is equivalent to doubling the heating source and can provide a larger amount of heat in a short time. For example, in the preheating stage of some large chemical reaction kettles or the initial stage of metal smelting, rapid temperature increase is required. The dual-mode circulation can work with two heating grids simultaneously to accelerate the heating rate and thus improve the efficiency of the entire production process.

[0047] Please refer to Figure 1-8, a heightening frame 302 located at the bottom of the inner wall of the chassis 1 is provided at the bottom of the structural frame 3. Limit rings 2081 are provided around the top of the sliding frame 208. The limit rings 2081 are sleeved on the shaft body of the vertical shaft 2082. The sliding frame 208 moves the vertical shaft 2082 back and forth, causing the second mounting frame 202 to also move back and forth. When the second mounting frame 202 moves back and forth, the vertical rod 209 also moves. When the first pulley 2092 and the second pulley 2093 of the vertical rod 209 move, when the vertical rod 209 enters the lowest groove of the special-shaped groove 305, the vertical rod 209 will pull the second mounting frame 202 downward, and the second mounting frame 202 realizes moving downward while moving. In the actual operation scenario, when it is necessary to start the heat cycle switching function of the device, the operator first turns on the first servo motor 5. After the first servo motor 5 starts, relying on its strong power output, it drives the connected first threaded shaft 206 to rotate at a high speed. Under the rotation of the first threaded shaft 206, the threaded slider 205 that closely cooperates with it slides smoothly and precisely back and forth along a specific path. Since there is a stable connection structure between the threaded slider 205 and the first mounting frame 201, the reciprocating motion of the threaded slider 205 directly drives the first mounting frame 201 to slide back and forth synchronously. During this process, the position of the first heating grid 2011 installed inside the first mounting frame 201 is also precisely adjusted accordingly to meet the requirements of different heat cycle working conditions. At the same time, in order to achieve an efficient position switching between the first mounting frame 201 and the second mounting frame 202, the operator synchronously starts the second servo motor 6. When the second servo motor 6 operates, it drives the second threaded shaft 212 to rotate at a high speed. Under the rotational driving force of the second threaded shaft 212, the threaded plate 211 flexibly moves back and forth on the established track. The threaded plate 211 is connected to the sliding frame 208 through a carefully designed connection component, enabling the movement of the threaded plate 211 to be seamlessly transmitted to the sliding frame 208, thereby driving the sliding frame 208 to move precisely back and forth. During the movement of the sliding frame 208, it is closely connected to the vertical shaft 2082, and its movement directly drives the vertical shaft 2082 to move back and forth along a specific track. There is a stable connection relationship between the vertical shaft 2082 and the second mounting frame 202, and the movement of the vertical shaft 2082 causes the second mounting frame 202 to also move back and forth accordingly. During the back-and-forth movement of the second mounting frame 202, the vertical rod 209 connected to it also moves synchronously. The top of the vertical rod 209 is equipped with a first pulley 2092, and the bottom is equipped with a second pulley 2093. These two pulleys roll on the inner track of the special-shaped groove 305. When the vertical rod 209 moves to a specific position such that the first pulley 2092 and the second pulley 2093 enter the lowest groove of the special-shaped groove 305, due to the special structural design of the special-shaped groove 305, the vertical rod 209 will be subjected to a downward acting force, thereby pulling the second mounting frame 202 downward. At this time, the second mounting frame 202 presents a combined motion state of moving downward while moving horizontally.When the second limit shaft 2091 re-enters the upper slot of the special-shaped groove 305, while the second mounting frame 202 continues to move horizontally, it experiences a process of first moving downward and then rising in the vertical direction. Through such a series of precise and complex movement processes, the second mounting frame 202 can cleverly make way for the moving first mounting frame 201, achieving an efficient switch between the two mounting frames and ensuring the stable operation and function expansion of the entire thermal cycle system.

[0048] Specifically, the working process or principle of this industrial production thermal cycle device: When in use, drive the first servo motor 5. Under the action of the first threaded shaft 206, the threaded slider 205 slides back and forth, causing the first mounting frame 201 to slide back and forth to adjust the position of the first heating mesh 2011. At the same time, drive the second servo motor 6. Under the action of the second threaded shaft 212, the threaded plate 211 moves back and forth, and then the sliding frame 208 moves back and forth. The sliding frame 208 moves the vertical shaft 2082 back and forth, causing the second mounting frame 202 to also move back and forth. When the second mounting frame 202 moves back and forth, the vertical rod 209 also moves. When the first pulley 2092 and the second pulley 2093 of the vertical rod 209 move, when the vertical rod 209 enters the lowest slot of the special-shaped groove 305, the vertical rod 209 will pull the second mounting frame 202 downward, and the second mounting frame 202 moves while moving downward. Then, when the second limit shaft 2091 re-enters the upper slot of the special-shaped groove 305, while the entire second mounting frame 202 is moving, it undergoes a process of first moving downward and then rising in the vertical direction to make way for the moving first mounting frame 201.

[0049] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
