Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurizer silos, and particularly relates to an environmental protection collection device for particulate matters in a desulfurizer silo. Background Technique

[0002] Desulfurizer generally refers to a reagent for removing free sulfur or sulfur compounds in fuels, raw materials or other materials. In the control and treatment of pollutants, it mainly refers to a reagent that can remove sulfur oxides in waste gas. Common desulfurizers are mostly solid particulate matters and are mostly stored in silos made of cement. However, during long-term storage, due to the physical property of the desulfurizer to absorb moisture, such particulate materials are likely to adhere to the inner wall of the silo, resulting in the phenomenon of caking and wall hanging, which will further cause the aperture of the feeding port to become smaller, affecting the feeding, and it is necessary to clean and recycle regularly. However, during actual cleaning, it often can only be completed by workers holding cleaning tools through the feeding pipe or manhole. Limited by the size of the feeding pipe or manhole, the cleaning operation is extremely inconvenient, time-consuming and laborious, and at the same time, there will be dust dispersion, which is not convenient and environmentally friendly enough and needs to be improved. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide an environmental protection collection device for particulate matters in a desulfurizer silo, which can realize automatic mechanized cleaning and collection of the silo wall hanging and effective dust removal to solve the above problems.

[0004] To achieve the above object, the technical solution adopted by the present utility model is: an environmental protection collection device for particulate matter in a desulfurizer silo, including a silo. The top of the silo is open, the bottom is in an inverted conical shape and is connected to a discharge pipe with a discharge valve. On the left and right outer side walls of the upper part of the silo, first hydraulic cylinders are vertically fixed. The piston rods of the two first hydraulic cylinders face upward and are fixedly connected to lifting seats. Rotating shafts are horizontally penetrated and arranged on the two lifting seats. One end of a rotating shaft far away from the other rotating shaft is drivingly connected to a first motor. A cover plate is fixedly connected between the two rotating shafts. The cover plate can be abutted and sealed on the top of the silo, and a feed pipe with a feed valve is communicated at a position corresponding to the inner side of the silo on it. A second hydraulic cylinder is vertically fixed at the center of the cover plate. The piston rod of the second hydraulic cylinder faces upward and is fixedly connected to a second motor. A dust collection hood is fixedly sleeved outside the second motor. The large-diameter end of the dust collection hood is open upward, the small-diameter end is closed downward, and a straight pipe is communicated at this end. The output shaft of the second motor faces upward and is fixedly connected to a square installation box. The top of the installation box is open, and a power-off holding electromagnet is fixedly arranged on the inner bottom. A magnetic installation block is inserted into the installation box. The installation block is magnetically connected to the power-off holding electromagnet. The upper part of the installation block extends out of the installation box, and a plurality of support rods are fixedly arranged on its peripheral side. The tail ends of the support rods are fixedly connected to a scraper. The scraper can be abutted on the inner side wall of the silo. A support plate is fixedly arranged on the outer side of the lower part of the silo. A dust collector and a suction fan are fixedly arranged on the support plate. The air inlet of the dust collector is communicated with a first hose, and the air outlet is communicated with the air inlet of the suction fan. The first hose can be communicated with the straight pipe through a first quick connector.

[0005] Preferably, the diameter of the cover plate is larger than the outer diameter of the silo.

[0006] Preferably, a sealing gasket is fixedly arranged on the lower side of the cover plate.

[0007] Preferably, the installation block is adapted to the installation box.

[0008] Preferably, a hot air blower is fixedly arranged on the support plate. The air outlet of the hot air blower is communicated with a second hose. The second hose can be communicated with the straight pipe through a second quick connector.

[0009] The beneficial effects of the present utility model are as follows: When the desulfurizer is stored normally, the piston rod of the first hydraulic cylinder is in a contracted state, and the cover plate presses against and closes on the top of the silo, sealing the silo to ensure the smooth storage of the desulfurizer. At this time, the piston rod of the second hydraulic cylinder faces upward, and the mounting block with a scraper is not installed, so as not to affect operations such as feeding. When it is necessary to clean the desulfurizer particles adhering to the inner wall of the desulfurizer silo, the discharge valve can be opened first, and the silo can be emptied through the discharge pipe. Then, the first hydraulic cylinder is operated to extend its piston rod, which can drive the entire cover plate to move upward to a suitable height. Next, the first motor is operated, and with the cooperation of the rotating shaft, the entire cover plate is driven to flip 180 degrees, so that the piston rod of the second hydraulic cylinder flips downward. After that, the mounting block with a scraper is fetched and inserted into the bottom of the mounting box at this time until the mounting block is magnetically connected to the power-off holding electromagnet, that is, the installation and fixation of the mounting block are completed. Then, the first hose is connected to the straight pipe through the first quick connector. Then, the second motor is operated, which can drive the mounting box, the mounting block and the scraper to rotate as a whole. At the same time, the second hydraulic cylinder is operated to extend its piston rod, driving the second motor to move downward as a whole, so as to cooperate to effectively scrape and remove the inner wall of the silo. The desulfurizer particles cleaned can be discharged through the discharge pipe and collected for reuse. During the process, the dust collection hood moves downward synchronously with the second motor. The exhaust fan is operated. Under the suction of the exhaust fan, the dust-laden air generated during scraping can be first collected at the dust collection hood and then flow into the dust collector through the first hose. After being effectively dust-removed by the dust collector, it is discharged from the air outlet of the exhaust fan, which can effectively avoid dust pollution. After the cleaning is completed, under the contraction of the piston rod of the second hydraulic cylinder, the second motor can be driven to move upward as a whole until the scraper is moved out of the silo. Then, the connection between the first hose and the straight pipe can be quickly disconnected through the first quick connector, and the circuit of the power-off holding electromagnet is connected to make it energized and demagnetized, releasing the magnetic attraction force on the mounting block, and the mounting block can be easily disassembled without affecting subsequent use. In this way, the automatic mechanized cleaning, collection and effective dust removal of the silo wall can be realized, the operation is simple, more time-saving and labor-saving, and more environmentally friendly and practical.

Specific embodiments

[0019] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0020] Such as Figures 1 to 8As shown in the figure, an environmental protection collection device for particulate matter in a desulfurizer silo includes a silo 1. The top of the silo 1 is open, the bottom is in an inverted conical shape and is connected to a discharge pipe 3 with a discharge valve 2. On the left and right outer side walls of the upper part of the silo 1, first hydraulic cylinders 4 are vertically fixed. The piston rods of the two first hydraulic cylinders 4 face upwards and are fixedly connected to lifting seats 5. A rotating shaft 6 is horizontally penetrated and rotatably arranged on each of the two lifting seats 5. One end of a rotating shaft 6 far from the other rotating shaft 6 is drivingly connected to a first motor 7. A cover plate 8 is fixedly connected between the two rotating shafts 6. The cover plate 8 can be abutted and sealed on the top of the silo 1, and a feed pipe 10 with a feed valve 9 is communicated at a position corresponding to the inner side of the silo 1 on it. A second hydraulic cylinder 11 is vertically fixed at the center of the cover plate 8. The piston rod of the second hydraulic cylinder 11 faces upwards and is fixedly connected to a second motor 12. A dust collection hood 13 is fixedly sleeved outside the second motor 12. The large-diameter end of the dust collection hood 13 is open upwards, the small-diameter end is closed downwards, and a straight pipe 14 is communicated at this end. The output shaft of the second motor 12 faces upwards and is fixedly connected to a square installation box 15. The top of the installation box 15 is open, and a power-off holding electromagnet 16 is fixed on the inner bottom. A magnetic installation block 17 is inserted into the installation box 15. The installation block 17 is magnetically attracted to the power-off holding electromagnet 16. The upper part of the installation block 17 extends out of the installation box 15, and a plurality of support rods 18 are fixedly arranged on its peripheral side. The tail ends of the support rods 18 are fixedly connected to a scraper 19. The scraper 19 can be abutted against the inner side wall of the silo 1. A support plate 20 is fixedly arranged on the outer side of the lower part of the silo 1. A dust collector 21 and a suction fan 22 are fixed on the support plate 20. The air inlet of the dust collector 21 is communicated with a first hose 23, and the air outlet is communicated with the air inlet of the suction fan 22. The first hose 23 can be communicated with the straight pipe 14 through a first quick connector 24;

[0021] When storing the desulfurizer normally, the piston rod of the first hydraulic cylinder 4 is in a contracted state, and the cover plate 8 presses against and covers the top of the silo 1 to seal the silo 1, ensuring the smooth storage of the desulfurizer. At this time, the piston rod of the second hydraulic cylinder 11 faces upward, and the mounting block 17 with the scraper 19 is not installed, so as not to affect operations such as feeding. When it is necessary to clean the desulfurizer particles adhering to the inner wall of the desulfurizer silo, the discharge valve 2 can be opened first to empty the silo 1 through the discharge pipe 3. Then, operate the first hydraulic cylinder 4 to extend its piston rod, which can drive the entire cover plate 8 to move upward to an appropriate height. Next, operate the first motor 7, which, in cooperation with the rotating shaft 6, drives the entire cover plate 8 to flip 180 degrees, enabling the piston rod of the second hydraulic cylinder 11 to flip downward. After that, bring the mounting block 17 with the scraper 19 and insert it into the bottom of the mounting box 15 at this time until the mounting block 17 is magnetically connected to the power-off holding electromagnet 16, thus completing the installation and fixation of the mounting block 17. Then, connect the first hose 23 to the straight pipe 14 through the first quick connector 24. Then, operate the second motor 12, which can drive the mounting box 15, the mounting block 17, and the scraper 19 to rotate as a whole. At the same time, operate the second hydraulic cylinder 11 to extend its piston rod, driving the second motor 12 to move downward as a whole, thus cooperating to effectively scrape and clean the inner wall of the silo 1. The desulfurizer particles cleaned can be discharged through the discharge pipe 3 and collected for reuse. During the process, the dust hood 13 moves downward synchronously with the second motor 12. Operate the exhaust fan 22. Under the suction of the exhaust fan 22, the dust-laden air generated during scraping can first be gathered at the dust hood 13 and then flow into the dust collector 21 through the first hose 23. After being effectively dust-removed by the dust collector 21, it is discharged from the air outlet of the exhaust fan 22, effectively avoiding dust pollution. After the cleaning is completed, under the contraction of the piston rod of the second hydraulic cylinder 11, the second motor 12 can be driven to move upward as a whole until the scraper 19 is moved out of the silo 1. Then, the connection between the first hose 23 and the straight pipe 14 can be quickly disconnected through the first quick connector 24, and the circuit of the power-off holding electromagnet 16 can be connected to make it energized and demagnetized, releasing the magnetic attraction on the mounting block 17, and the mounting block 17 can be easily disassembled without affecting subsequent use. In this way, the automatic mechanized cleaning, collection, and effective dust removal of the wall of the silo 1 can be realized. The operation is simple, more time-saving and labor-saving, and more environmentally friendly and practical. The first motor 7 can adopt an existing conventional stepping motor with a brake function to cooperate to achieve rotation at a corresponding angle and position locking after rotation. The power-off holding electromagnet 16 is an existing technology, suitable for environments that require long-term holding of suction. Compared with ordinary electromagnets that generate magnetism when powered on and demagnetize when powered off, it is just the opposite, having the characteristics of demagnetizing when powered on and having magnetism when powered off, which can reduce power consumption and is more practical. The mounting block 17 can be made of existing conventional magnetic metal materials such as iron. The dust collector 21 can adopt an existing conventional belt dust collector, etc.

[0022] In this embodiment, the diameter of the cover plate 8 is larger than the outer diameter of the silo 1 to ensure that the cover plate 8 has sufficient area to cover and seal the silo without affecting the storage of desulfurizer.

[0023] In this embodiment, a sealing gasket 25 is fixedly arranged on the lower side of the cover plate 8 to ensure the sealing performance when the cover plate 8 seals the silo 1 without affecting the storage quality of the desulfurizer.

[0024] In this embodiment, the mounting block 17 is adapted to the mounting box 15 to ensure the smooth installation of the mounting block 17.

[0025] In this embodiment, a hot air blower 26 is fixedly arranged on the support plate 20. A second hose 27 is connected to the air outlet of the hot air blower 26. The second hose 27 can be connected to the straight pipe 14 through a second quick connector 28. After scraping and dust collection of the silo 1 are completed, the mounting block 17 can be removed first, and the connection between the first hose 23 and the straight pipe 14 can be disconnected through the first quick connector 24. Then, the second hose 27 can be connected to the straight pipe 14 through the second quick connector 28, and then the hot air blower 26 is operated. Hot air can be generated and conveyed to the dust collection hood 13 through the second hose 27 and the straight pipe 14. At this time, the dust collection hood 13 can play a role in dispersing the hot air and disperse the hot air into the silo 1. At the same time, the second hydraulic cylinder 11 is started. By the reciprocating telescopic movement of the piston rod of the second hydraulic cylinder 11, the second motor 12 and the dust collection hood 13 as a whole can be driven to move up and down reciprocally. Thus, the inner side wall of the silo 1 can be effectively dried by using the hot air, which can greatly reduce the humidity of the inner side wall of the silo 1, and thus is more conducive to the storage of the next batch of desulfurizer, making the whole device more practical. The hot air blower 26 can adopt the existing technology. Both the first quick connector 24 and the second quick connector 28 can adopt the existing technology. Generally, they are composed of a male head and a female head. The male head or the female head can be preset on the first hose 23 and the second hose 27, and the corresponding female head or male head can be preset on the straight pipe 14 for matching use.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
