Description

Technical Field

[0001] The invention relates to the technical field of steam boilers, in particular to a steam boiler for coarse grain processing. Background Art

[0002] A steam boiler refers to a boiler equipment that produces steam. A steam boiler can efficiently convert the chemical energy in the fuel into thermal energy and transfer it in the form of steam.

[0003] Steam boilers generate high-temperature combustion gases by burning fuel. There is a water reservoir inside the boiler. The combustion gases are heated by the inner wall of the boiler and the pipes, heating the water in the reservoir. The heated water comes into contact with the high-temperature combustion gases, and the water absorbs heat and turns into steam. Steam accumulates inside the boiler and gradually increases in pressure. When the internal pressure of the steam boiler reaches the set value, the steam will be transported to where it is needed through the pipeline system.

[0004] When processing coarse grains, superheated steam can effectively inhibit the activity of lipid oxidation-related enzymes in the coarse grains, thereby maintaining the freshness and quality of the coarse grains. Superheated steam treatment can avoid the loss of nutrients in the coarse grains that are easily oxidized by high temperature. In the prior art, the steam of the steam boiler is directly transported to the coarse grain processing site for processing, and the temperature and pressure of the steam are set in the steam boiler to adapt to different types of coarse grains, processing purposes and process requirements. However, it is mainly controlled in the steam boiler body and cannot take into account the coarse grain processing site. When steam continuously enters the coarse grain processing site, its internal pressure is too high, or the internal steam is not discharged in time, resulting in condensation of the internal steam, resulting in poor processing effect on the coarse grains, making the processing effect of the coarse grains inconsistent, so we propose a steam boiler for coarse grain processing.

[0020] The present invention discloses a steam boiler for coarse grain processing, which has the following beneficial effects:

[0021] The steam boiler for processing coarse grains is started up, and under the action of the steam pressure in the steam boiler body, the steam pushes the gas pipe to move from the hole opened in the air inlet seat. At this time, the gas pipe slides along the outer peripheral wall of the sealing seat. When the sealing seat is separated from the gas pipe, it is at a suitable steam pressure. The steam enters the connecting pipe through the gas pipe, is transmitted through the connecting pipe and enters the connecting cylinder, and enters the storage box through the connecting cylinder to process the coarse grains. When the steam pressure in the steam boiler body is too high, the gas pipe is pushed to move without blocking the outlet branch pipe. At this time, part of the steam is discharged outward through the outlet branch pipe. The discharge of steam through the outlet branch pipe reduces the pressure in the steam boiler body, ensures the steam pressure in the storage box by the steam boiler body, and improves the processing effect on the coarse grains.

[0022] In the steam boiler for processing coarse grains, the steam in the connecting cylinder pushes the pushing block to slide in the connecting seat, so that the pushing block drives the sliding rod to slide in the connecting seat, and the first rotating seat moves accordingly. At the same time, the pushing block compresses the second spring. Under the rebound of the second spring, the moving distance of the sliding rod is limited, which is proportional to the pressure in the connecting cylinder, thereby effectively limiting the steam pressure in the storage box.

[0023] The steam boiler for coarse grain processing drives a transmission rod to rotate through a first rotating seat, and the transmission rod drives the first transmission seat to rotate, and drives the second transmission seat and the third transmission seat to rotate respectively. Under the rotation of the third transmission seat, the opening angle of the pressure relief port of the solenoid valve is controlled, and the steam discharge rate in the storage box is controlled to avoid excessive pressure inside the storage box, or untimely discharge of internal steam, which leads to condensation of internal steam, resulting in poor processing effect on the coarse grains and uneven processing effect of the coarse grains.

[0024] For the steam boiler for coarse grain processing, when the first transmission seat rotates to drive the second transmission seat to rotate, when the second transmission seat rotates and contacts the control switch below it, the steam boiler body is shut down by the control switch to avoid continuous steam generation, ensure the pressure safety in the steam boiler body, and avoid continuous production safety hazards.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present application provides a steam boiler for coarse grain processing, which solves the problem that the temperature and pressure of steam are controlled in the steam boiler body, and the coarse grain processing cannot be taken into account. When steam continuously enters the coarse grain processing, its internal pressure is too high, or the internal steam is not discharged in time, resulting in condensation of internal steam, resulting in poor processing effect on the coarse grains, and making the processing effect of the coarse grains inconsistent. The steam boiler body 1 is started, and under the action of the steam pressure in the steam boiler body 1, the steam pushes the air pipe 404 to move from the hole opened in the air inlet seat 401. At this time, the air pipe 404 slides along the outer peripheral wall of the sealing seat 402. When the sealing seat 402 is separated from the air pipe 404, it is at a suitable steam pressure. The steam enters the connecting pipe 5 through the air pipe 404, is transmitted through the connecting pipe 5 to enter the connecting cylinder 7, and enters the storage box 2 through the connecting cylinder 7 to process the coarse grains.

[0039] When the steam pressure in the steam boiler body 1 is too high, the gas pipe 404 is pushed to move so as not to block the gas outlet branch pipe 301. At this time, part of the steam is discharged outward through the gas outlet branch pipe 301. The steam discharged through the gas outlet branch pipe 301 reduces the pressure in the steam boiler body 1, ensures the steam pressure in the storage box 2 by the steam boiler body 1, and improves the processing effect of the coarse grains.

[0040] The steam in the connecting tube 7 pushes the push block 805 to slide in the connecting seat 801, so that the push block 805 drives the sliding rod 802 to slide in the connecting seat 801, and the first rotating seat 804 moves accordingly. At the same time, the push block 805 compresses the second spring 803. Under the rebound of the second spring 803, the moving distance of the sliding rod 802 is limited, which is proportional to the pressure in the connecting tube 7, and the steam pressure in the storage box 2 is effectively limited.

[0041] The transmission rod 901 is pushed to rotate by the first rotating seat 804, and the transmission rod 901 drives the first transmission seat 902 to rotate, and drives the second transmission seat 903 and the third transmission seat 904 to rotate respectively. Under the rotation of the third transmission seat 904, the opening angle of the solenoid valve pressure relief port 602 is controlled, and the steam discharge rate in the storage box 2 is controlled to avoid excessive internal pressure in the storage box 2, or untimely discharge of internal steam, which leads to condensation of internal steam, resulting in poor treatment effect of coarse grains and uneven treatment effect of coarse grains.

[0042] When the first transmission seat 902 rotates to drive the second transmission seat 903 to rotate, when the second transmission seat 903 rotates and contacts the control switch below it, the steam boiler body 1 is turned off by the control switch to avoid continuous steam generation, thereby ensuring the pressure safety in the steam boiler body 1 and avoiding continuous production safety hazards.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The embodiment of the invention discloses a steam boiler for coarse grain processing.

[0045] According to the attached Figure 1-10 As shown, it includes a steam boiler body 1 and an air outlet pipe 3, a storage box 2 and a pressure limiting unit 4. The air outlet pipe 3 is fixedly connected to the steam boiler body 1, and an air outlet branch pipe 301 is fixedly connected to the outer peripheral wall of the air outlet pipe 3. The pressure limiting unit 4 is arranged in the air outlet pipe 3.

[0046] The pressure limiting unit 4 includes an air inlet seat 401, a sealing seat 402 and an air delivery pipe 404. The air inlet seat 401 is fixedly connected to the inner wall of the air outlet pipe 3. The sealing seat 402 is fixedly connected to the air inlet seat 401. The air delivery pipe 404 is slidably connected to the sealing seat 402. The air delivery pipe 404 is outside the air outlet pipe 3.

[0047] A connecting pipe 5 is inserted into the top end face of the gas delivery pipe 404, and the other end of the connecting pipe 5 is inserted into the inner wall of a connecting cylinder 7, and the connecting cylinder 7 is connected to the storage box 2. The steam boiler body 1 is started, and under the action of the steam pressure in the steam boiler body 1, the steam pushes the gas delivery pipe 404 from the hole opened in the air inlet seat 401 to move. At this time, the gas delivery pipe 404 slides along the outer peripheral wall of the sealing seat 402. When the sealing seat 402 is separated from the gas delivery pipe 404, it is at a suitable steam pressure. The steam enters the connecting pipe 5 through the gas delivery pipe 404, is transmitted through the connecting pipe 5 and enters the connecting cylinder 7, and enters the storage box 2 through the connecting cylinder 7 to process the coarse grains.

[0048] It is particularly disclosed that when the steam pressure in the steam boiler body 1 is too high, the gas supply pipe 404 is pushed to move so as not to block the gas outlet branch pipe 301. At this time, part of the steam is discharged outward through the gas outlet branch pipe 301. The steam discharged through the gas outlet branch pipe 301 reduces the pressure in the steam boiler body 1, thereby ensuring the steam pressure in the storage box 2 by the steam boiler body 1 and improving the processing effect of the coarse grains.

[0049] The storage box 2 is provided with a sealing cover 6, a connecting tube 7 is provided on the sealing cover 6, a pressure unit 8 and a transmission unit 9 are provided on the sealing cover 6, the pressure unit 8 is provided on the side of the connecting tube 7, and the transmission unit 9 is connected with the pressure unit 8 and the sealing cover 6.

[0050] The pressure unit 8 includes a connecting seat 801 and a sliding rod 802. The connecting seat 801 is fixedly connected to the outer wall of the connecting cylinder 7. The connecting seat 801 is communicated with the interior of the connecting cylinder 7. The sliding rod 802 is slidably connected to the inner wall of the connecting seat 801. The end of the sliding rod 802 is fixedly connected to the first rotating seat 804. The steam in the connecting cylinder 7 pushes the pushing block 805 to slide in the connecting seat 801, so that the pushing block 805 drives the sliding rod 802 to slide in the connecting seat 801, and the first rotating seat 804 moves accordingly. At the same time, the pushing block 805 compresses the second spring 803. Under the rebound of the second spring 803, the moving distance of the sliding rod 802 is limited, which is proportional to the pressure in the connecting cylinder 7, and the steam pressure in the storage box 2 is effectively limited.

[0051] The transmission unit 9 includes a transmission rod 901, a first transmission seat 902, a second transmission seat 903 and a third transmission seat 904. One end of the transmission rod 901 is rotatably connected to the first rotating seat 804, and the other end of the transmission rod 901 is rotatably connected to the first transmission seat 902. The second transmission seat 903 and the third transmission seat 904 are arranged on both sides of the first transmission seat 902. The first rotating seat 804 pushes the transmission rod 901 to rotate, and the transmission rod 901 drives the first transmission seat 902 to rotate, and drives the second transmission seat 903 and the third transmission seat 904 to rotate respectively. Under the rotation of the third transmission seat 904, the opening angle of the solenoid valve pressure relief port 602 is controlled, and the steam discharge rate in the storage box 2 is controlled to avoid excessive internal pressure in the storage box 2, or untimely discharge of internal steam, resulting in condensation of internal steam, resulting in poor treatment effect of coarse grains, and the problem of uneven treatment effect of coarse grains.

[0052] It should be particularly emphasized that when the first transmission seat 902 rotates to drive the second transmission seat 903 to rotate, when the second transmission seat 903 rotates and contacts the control switch below it, the steam boiler body 1 is turned off by the control switch to avoid continuous steam generation, thereby ensuring the pressure safety in the steam boiler body 1 and avoiding continuous production safety hazards.

[0053] A sliding seat 403 is slidably connected to the inner wall of the gas outlet pipe 3. The sliding seat 403 is fixedly connected to the outer wall of the gas delivery pipe 404. The sliding seat 403 fits the top end surface of the gas inlet seat 401. The sliding seat 403 is used to block the connection between the gas outlet branch pipe 301 and the gas outlet pipe 3. Under the action of the steam pressure in the steam boiler body 1, the steam pushes the sliding seat 403 and the gas delivery pipe 404 to move from the hole opened in the gas inlet seat 401. At this time, the gas delivery pipe 404 slides along the outer peripheral wall of the sealing seat 402.

[0054] It is particularly disclosed that when the steam pressure in the steam boiler body 1 is too high, the gas supply pipe 404 is pushed to move so as not to block the gas outlet branch pipe 301. At this time, part of the steam is discharged outward through the gas outlet branch pipe 301. The steam discharged through the gas outlet branch pipe 301 reduces the pressure in the steam boiler body 1, thereby ensuring the steam pressure in the storage box 2 by the steam boiler body 1 and improving the processing effect of the coarse grains.

[0055] The outer peripheral wall of the gas delivery pipe 404 is sleeved with a first spring 405, one end of the first spring 405 is fixedly connected to the sliding seat 403, the other end of the first spring 405 is fixedly connected to a moving seat 406, the moving seat 406 is threadedly connected to the inner wall of the gas outlet pipe 3, the top end surface of the moving seat 406 is fixedly connected to an adjustment seat 407, the adjustment seat 407 is slidably connected to the outer peripheral wall of the gas delivery pipe 404, when the sliding seat 403 moves, the sliding seat 403 compresses the first spring 405, and the first spring 405 exerts a reverse thrust on the gas delivery pipe 404;

[0056] Furthermore, when the sealing seat 402 is separated from the gas pipe 404, the steam pressure is suitable, and the steam enters the connecting pipe 5 through the gas pipe 404 and is transmitted through the connecting pipe 5. When the steam pressure to be transmitted needs to be adjusted, the movable seat 406 is driven to rotate by rotating the adjustment seat 407, and the movable seat 406 rotates along the inner wall of the gas outlet pipe 3, thereby adjusting the position of the movable seat 406 and changing the compression degree of the first spring 405, so that the pressure separating the gas pipe 404 and the sealing seat 402 is adjusted.

[0057] The top end face of the storage box 2 is fixedly connected to a guide frame 601, the sealing cover 6 is slidably connected to the inner wall of the guide frame 601, the top end face of the guide frame 601 is fixedly connected to a solenoid valve pressure relief port 602, an air intake pipe 701 is plugged into the inner wall of the sealing cover 6, and the air intake pipe 701 is connected to both ends of the connecting tube 7. When steam enters the connecting tube 7 through the connecting pipe 5, the steam is transmitted to the storage box 2 through the air intake pipe 701, and the coarse grains in the storage box 2 are processed.

[0058] The outer wall of the connecting tube 7 is fitted with a pushing block 805, which is fixedly connected to the side of the sliding rod 802 away from the first rotating seat 804. The outer peripheral wall of the sliding rod 802 is sleeved with a second spring 803, one end of the second spring 803 is fixedly connected to the pushing block 805, and the other end of the second spring 803 is fixedly connected to the connecting seat 801.

[0059] Furthermore, when the pressure in the storage box 2 is too high, the pressure in the air inlet pipe 701 and the connecting tube 7 is too high, causing the pressure unit 8 to transmit. At this time, the steam in the connecting tube 7 pushes the push block 805 to slide in the connecting seat 801, so that the push block 805 drives the sliding rod 802 to slide in the connecting seat 801. At the same time, the push block 805 compresses the second spring 803. Under the rebound of the second spring 803, the moving distance of the sliding rod 802 is limited, which is proportional to the pressure in the connecting tube 7.

[0060] The top end surface of the sealing cover 6 is fixedly connected to a support frame 908, and a connecting shaft is rotatably connected to the inner wall of the support frame 908. The connecting shaft in the support frame 908 is respectively inserted into the inner walls of the second transmission seat 903 and the third transmission seat 904, and the end of the connecting shaft is rotatably connected to the corresponding first transmission seat 902. The second transmission seat 903 and the third transmission seat 904 are connected to the corresponding first transmission seat 902 via the rotating shaft.

[0061] As the sliding rod 802 moves, the first rotating seat 804 moves accordingly, so that the first rotating seat 804 pushes the transmission rod 901 to rotate, and the transmission rod 901 drives the first transmission seat 902 to rotate. The first transmission seat 902 rotates in the support frame 908 through the connecting shaft. As the first transmission seat 902 rotates, the second transmission seat 903 and the third transmission seat 904 are driven to rotate respectively;

[0062] It is particularly disclosed that the first transmission seat 902 is set as an irregular circle, the protruding end of the first transmission seat 902 is rotatably connected to the transmission rod 901, the second transmission seat 903 is set to protrude at one end, and the protruding end is set in an arc shape, and the control switch of the steam boiler body 1 is set directly below the second transmission seat 903.

[0063] A rotating rod 905 is rotatably connected to the side of the third transmission seat 904 . The rotating rod 905 is rotatably connected to the edge of the third transmission seat 904 . One end of the rotating rod 905 away from the third transmission seat 904 is rotatably connected to the second rotating seat 906 .

[0064] It should be particularly emphasized that the end of the second rotating seat 906 is fixedly connected to the moving rod 907, the second rotating seat 906 is slidably connected to the sealing cover 6, the end of the moving rod 907 is transmission connected to the position sensor, the position sensor is connected to the EPEC controller, the position sensor and the EPEC controller are existing mature mechanisms, the position sensor model is GT2-P12KF, and the EPEC controller model is EPEC2024, which will not be elaborated in this application.

[0065] When the third transmission seat 904 rotates, the third transmission seat 904 drives the rotating rod 905 to rotate accordingly, so that the rotating rod 905 pushes the second rotating seat 906 to move, and the moving rod 907 moves at the same time. The movement of the moving rod 907 is linked to the position sensor, and the EPEC controller is started to control the opening angle of the solenoid valve pressure relief port 602, thereby controlling the steam discharge rate in the storage box 2;

[0066] When the pressure in the storage box 2 decreases as the steam is discharged, the pressure in the connecting tube 7 decreases accordingly, and the push block 805, the sliding rod 802 and the first rotating seat 804 decrease accordingly, driving the third transmission seat 904 to rotate in the opposite direction, controlling the opening angle of the solenoid valve pressure relief port 602, and ensuring that the pressure in the storage box 2 is within the set pressure limit range.

[0067] When the first transmission seat 902 rotates to drive the second transmission seat 903 to rotate, when the second transmission seat 903 rotates and contacts the control switch below it, the steam boiler body 1 is turned off by the control switch to avoid continuous steam generation, thereby ensuring the pressure safety in the steam boiler body 1 and avoiding continuous production safety hazards.

[0068] Working principle: The cleaned coarse grains are sent into the storage box 2, and the steam boiler body 1 is started. A pressure control system is installed in the steam boiler body 1, which can maintain the pressure inside the steam boiler body 1 within a set range by adjusting the amount of fuel supplied, controlling the intensity of combustion and exhausting exhaust gas. When the internal pressure of the steam boiler reaches the set value, the steam will be transported to the storage box 2 through the pipeline system.

[0069] At this time, under the action of the steam pressure in the steam boiler body 1, the steam pushes the sliding seat 403 and the gas pipe 404 from the hole opened in the gas inlet seat 401 to move, and the gas pipe 404 slides along the outer peripheral wall of the sealing seat 402. When the sliding seat 403 moves, the sliding seat 403 compresses the first spring 405, and the first spring 405 exerts a reverse thrust on the gas pipe 404;

[0070] When the sealing seat 402 is separated from the gas pipe 404, the steam pressure is appropriate at this time, and the steam enters the connecting pipe 5 through the gas pipe 404 and is transmitted through the connecting pipe 5. When the steam pressure to be transmitted needs to be adjusted, the movable seat 406 is driven to rotate by rotating the adjusting seat 407, and the movable seat 406 rotates along the inner wall of the gas outlet pipe 3, thereby adjusting the position of the movable seat 406 and changing the compression degree of the first spring 405, so that the pressure of the gas pipe 404 and the sealing seat 402 separating is adjusted;

[0071] When the steam pressure in the steam boiler body 1 is too high, the gas pipe 404 is pushed to move so as not to block the gas outlet branch pipe 301. At this time, part of the steam is discharged outward through the gas outlet branch pipe 301. The steam discharged through the gas outlet branch pipe 301 reduces the pressure in the steam boiler body 1, ensures the steam pressure in the storage box 2 by the steam boiler body 1, and improves the processing effect of the coarse grains.

[0072] When the steam enters the connecting tube 7 through the connecting tube 5, the steam is transmitted to the storage box 2 through the air inlet pipe 701 to process the coarse grains in the storage box 2. When the pressure in the storage box 2 is too high, the pressure in the air inlet pipe 701 and the connecting tube 7 is too high, causing the pressure unit 8 to transmit;

[0073] At this time, the steam in the connecting tube 7 pushes the pushing block 805 to slide in the connecting seat 801, so that the pushing block 805 drives the sliding rod 802 to slide in the connecting seat 801, and at the same time, the pushing block 805 compresses the second spring 803. Under the rebound of the second spring 803, the moving distance of the sliding rod 802 is limited, which is proportional to the pressure in the connecting tube 7.

[0074] As the sliding rod 802 moves, the first rotating seat 804 moves accordingly, so that the first rotating seat 804 pushes the transmission rod 901 to rotate, and the transmission rod 901 drives the first transmission seat 902 to rotate. The first transmission seat 902 rotates in the support frame 908 through the connecting shaft. As the first transmission seat 902 rotates, the second transmission seat 903 and the third transmission seat 904 are driven to rotate respectively;

[0075] When the third transmission seat 904 rotates, the third transmission seat 904 drives the rotating rod 905 to rotate accordingly, so that the rotating rod 905 pushes the second rotating seat 906 to move, and the moving rod 907 moves at the same time. The movement of the moving rod 907 is linked to the position sensor, and the EPEC controller is started to control the opening angle of the solenoid valve pressure relief port 602, thereby controlling the steam discharge rate in the storage box 2;

[0076] When the pressure in the storage box 2 decreases as the steam is discharged, the pressure in the connecting tube 7 decreases accordingly, and the push block 805, the sliding rod 802 and the first rotating seat 804 decrease accordingly, driving the third transmission seat 904 to rotate in the opposite direction, controlling the opening angle of the solenoid valve pressure relief port 602, and ensuring that the pressure in the storage box 2 is within the set pressure limit range.

[0077] When the first transmission seat 902 rotates to drive the second transmission seat 903 to rotate, when the second transmission seat 903 rotates and contacts the control switch below it, the steam boiler body 1 is turned off by the control switch to avoid continuous steam generation, thereby ensuring the pressure safety in the steam boiler body 1 and avoiding continuous production safety hazards.
