Description

Technical Field

[0001] The invention relates to the technical field of carbon black production, in particular to a novel safety dispersing device for carbon black production. Background Art

[0002] During the carbon black production process, if the carbon black production is unstable, it will inevitably cause excessive pressure inside the main bag box, which will damage the bag filter in the box. At the same time, when the machine is just started or shut down for maintenance, the box must be ventilated to the atmosphere. Therefore, a release device must be installed on the main bag.

[0003] For example, a safety release device for carbon black production with publication number CN114504883B includes: a cylinder, a sealing cover is hinged on the upper part of the cylinder; a cylinder is arranged on the side of the cylinder and is movably connected to the sealing cover, and the cylinder is used to drive the sealing cover to move; a control valve, whose input end is respectively connected to the production system and the compressed air output device, and whose output end is connected to the cylinder, and the control valve is used to control the movement of the cylinder according to the pressure state of the production system. The present invention drives the sealing cover by the cylinder, thereby controlling the opening and closing of the cylinder, and controls the movement of the cylinder by the control valve to automatically control the opening and closing of the cylinder. The setting of the cylinder can not only ensure the sealing performance between the sealing cover and the cylinder, but also the control valve controls the movement of the cylinder according to the pressure state of the production system. When the pressure of the production system is too high, the cylinder is promptly controlled to release the pressure inside the cylinder, thereby ensuring that the bag filter inside the cylinder is not damaged.

[0004] During the carbon black production process and the exhaust gas collection and delivery process, when the system pressure exceeds the safe pressure range and manual release is used, the operator must quickly climb to the top of the four-story main bag to perform manual operation. The slow reaction can easily cause equipment safety failures and endanger personal safety.

[0005] Therefore, we proposed a new type of safe release device for carbon black production in order to solve the problems raised above. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the pressure of the exhaust gas is too high, that is, the flat plate, the first connecting tube, the first conical tube, and the second connecting tube rotate upward, the exhaust gas can be discharged from the first through hole to relieve the pressure of the device. The exhaust gas is continuously discharged and a vortex is formed in the second conical tube, which can throw out the debris particles to a certain extent and improve the purity of the exhaust gas release. The particles sprayed from the first through hole can be re-discharged into the discharge pipe body from the second through hole, preventing some carbon black iron filings from gushing out and reducing environmental pollution. This device adopts automatic discharge and eliminates manual discharge, which effectively solves the equipment damage caused by pressure fluctuations, saves manual labor, and improves the safety factor.

[0022] 2. The diameter of the vent pipe body 21 is expanded and adjusted from the original φ700 and φ500 to φ900, which greatly increases the filtration area. The removal of manual venting effectively solves the equipment damage caused by pressure fluctuations and has a good protective effect.

[0023] 3. The airflow ejected from the first through hole can continuously drive the fan blades, the inner cylinder, and the second conical cylinder to rotate. The rotation of the second conical cylinder will drive the airflow to vortex, thereby throwing the heavier particles to both sides of the second conical cylinder, and finally pouring them back into the discharge pipe body from the second through hole, which can effectively separate solids and gases, prevent particles from being discharged from the outside of the discharge pipe body, and further play a protective role.

[0024] 4. By setting the drainage hole, it can effectively drain water and dust when it rains. When the inner cylinder rotates, the one-way ratchet, one-way pawl and limit ring rotate together, which can drive the scraper to slide on the upper end of the drainage hole, thereby clearing the accumulated water or blocked dust on the drainage hole.

[0025] 5. Six arc plates are combined into a circular structure, which is closed at the upper end of the inner cylinder, further sealing the discharge pipe body. When the pressure of the exhaust gas is too high, multiple arc plates are deployed at the same time to limit the particles flying upwards. Therefore, the debris particles can only be discharged downwards, which is suitable for the safe discharge of exhaust gas.

[0026] 6. Through the cooperation between the one-way ratchet and the one-way pawl, the inner cylinder can be driven to rotate together during the rotation of the motor, and the arc plate can be driven to close unilaterally, ensuring that the device can be opened and closed, which is convenient for manual operation.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0037] Example 1: Please refer to Figure 1-Figure 4 The present invention provides a technical solution: a new type of safe venting device for carbon black production, including a production mechanism 1 and a venting pipe mechanism 2 installed on the production mechanism 1. During the exhaust emission process of the carbon black production process, the venting pipe mechanism 2 plays a role of safety protection.

[0038] The emission pipe mechanism 2 comprises a emission pipe body 21 , and the exhaust gas is discharged from the emission pipe body 21 .

[0039] An inner groove 22 is formed at the upper end of the inner wall of the diffusion pipe body 21 , and a spiral inner groove 23 is formed at the lower end of the groove wall of the inner groove 22 .

[0040] A first limiting mechanism 4 is arranged inside the discharge pipe mechanism 2, and the first limiting mechanism 4 includes a flat plate 41, and a threaded protrusion 47 is provided on the outer periphery of the flat plate 41, and the threaded protrusion 47 is threadedly connected to the spiral inner groove 23. The upper end of the flat plate 41 is connected and installed with a first connecting tube 42, and the upper end of the first connecting tube 42 is connected with a first conical tube 43, and the upper end of the first conical tube 43 is connected with a second connecting tube 44, and a first through hole 45 is provided on the outer periphery of the second connecting tube 44, and the first through hole 45 has an inclined structure.

[0041] A dust removal mechanism 5 is provided at the upper end of the first limiting mechanism 4, and the dust removal mechanism 5 includes an inner cylinder body 51 rotatably mounted on the outer periphery of the discharge pipe body 21, a second conical cylinder 52 is fixedly mounted on the inner wall of the inner cylinder body 51, the lower end of the second conical cylinder 52 is connected to the limiting cylinder 53, and the second connecting cylinder 44 is arranged inside the limiting cylinder 53.

[0042] The limiting cylinder 53 blocks the first through hole 45 of the second connecting cylinder 44, so that the flat plate 41, the first connecting cylinder 42, the first conical cylinder 43, and the second connecting cylinder 44 are combined into a cylindrical structure which is closed on the top and open on the bottom. The exhaust gas enters the discharge pipe body 21 and surges upward. The exhaust gas will not leak from the upper end, and it also prevents rainwater or other dust from entering the interior of the production mechanism 1, which has a safety sealing effect.

[0043] The position of the discharge pipe body 21 is fixed. When the pressure of the exhaust gas is too large, the pressure squeezes the second connecting tube 44 upward, and the second connecting tube 44 and the plate 41 move upward. At this time, the threaded protrusion 47 on the outer periphery of the plate 41 is threadedly connected with the spiral inner groove 23, that is, the plate 41, the first connecting tube 42, the first conical tube 43, and the second connecting tube 44 rotate upward until the first through hole 45 of the second connecting tube 44 is higher than the limiting tube 53, and the exhaust gas can be discharged from the first through hole 45 to relieve the pressure of the device. After the pressure is restored, the second connecting tube 44 is reset and the discharge pipe body 21 can be blocked again.

[0044] During the process of pressure release, the exhaust gas is discharged through the first through hole 45. The first through hole 45 has an inclined structure. The exhaust gas is continuously discharged and will be directly sprayed on the inner wall of the second conical cylinder 52, thereby forming a vortex in the second conical cylinder 52. Debris particles can be thrown out to a certain extent, thereby improving the purity of the exhaust gas release.

[0045] A second through hole 54 is provided on the second conical tube 52, and the particles sprayed from the first through hole 45 can be discharged back into the emission pipe body 21 from the second through hole 54, thereby preventing some carbon black iron filings from gushing out and reducing environmental pollution. At the same time, the exhaust gas is discharged upward in a spiral shape, which has a certain anti-blocking effect and ensures the uniformity of exhaust gas release.

[0046] The device adopts automatic release and eliminates manual release, which effectively solves the problem of equipment damage caused by pressure fluctuations, saves manual labor, and improves the safety factor.

[0047] Example 2: Please refer to Figure 1-Figure 4 The production mechanism 1 includes cloth bags 11. The upper ends of the two cloth bags 11 are connected to an exhaust pipe 13 through a first through pipe 12. One end of the exhaust pipe 13 is connected to an exhaust gas pressurizing fan 14. The upper end of the exhaust pipe 13 is also connected to a discharge pipe body 21 through a second through pipe 15. The diameter of the discharge pipe body 21 is enlarged and adjusted from φ700 and φ500 of the raw material to φ900. The filtering area is greatly improved, and the elimination of manual discharge effectively solves the equipment damage caused by pressure fluctuations.

[0048] The first through pipe 12 and the second through pipe 15 can be composed of any connectors such as double-way pipes, three-way pipes, etc. that are adapted to the number of pipes. After the exhaust gas is generated, it can enter the exhaust pipe 13 and finally enter the emission pipe body 21.

[0049] A first feed hole 46 is formed at the upper end of the flat plate 41 .

[0050] A fixing ring 24 is fixedly mounted on the inner wall of the emission pipe body 21 . The fixing ring 24 is connected to the first connecting tube 42 . The fixing ring 24 is located at the lower end of the flat plate 41 . A second feed hole 25 offset from the first feed hole 46 is formed on the fixing ring 24 .

[0051] In the initial state, the plate 41 is located at the upper end of the fixed ring 24, the first feed hole 46 and the second feed hole 25 are offset, and the limiting cylinder 53 blocks the first through hole 45 of the second connecting cylinder 44, so that the plate 41, the first connecting cylinder 42, the first conical cylinder 43, and the second connecting cylinder 44 are combined into a cylindrical structure with a closed top and an open bottom, with double limiting. When the exhaust gas is discharged, the first feed hole 46 and the second feed hole 25 are connected, the first through hole 45 is connected to the outside air, and the height of the second conical cylinder 52 is relatively high. Some waste slag particles are discharged from the first through hole 45, and finally fall into the interior of the discharge pipe body 21 from the first feed hole 46 and the second feed hole 25, which has the function of filtering and receiving materials, and has a good protection effect.

[0052] Example 3: Please refer to Figure 2-Figure 4 A first connecting block 55 is commonly installed on the outer periphery of the upper end of the inner cylinder 51, and a plurality of fan blades 56 are fixedly installed on the inner wall of the upper end of the second conical cylinder 52. The fan blades 56 are inclined. It should be noted that the diameter of the first through hole 45 is smaller than the diameter of the second through hole 54. The first through hole 45 is an inclined hole, and the inclination angle of the fan blades 56 is opposite to the inclination direction of the first through hole 45.

[0053] The exhaust gas is ejected from the first through hole 45, and the direction of the high-pressure airflow is just applied to the fan blades 56. Therefore, the airflow ejected from the first through hole 45 can continuously drive the fan blades 56, the inner cylinder 51, and the second conical cylinder 52 to rotate. The second conical cylinder 52 will drive the airflow to vortex during rotation, and then throw the heavier particles to both sides of the second conical cylinder 52, and finally pour them back into the discharge pipe body 21 from the second through hole 54, which can effectively separate solids and gases, prevent particles from being discharged from the outside of the discharge pipe body 21, and further play a protective role.

[0054] Example 4: Please refer to Figure 2-Figure 5 The upper ends of the driving mechanism 3 and the dust removal mechanism 5 are jointly provided with a mounting mechanism 6, and the mounting mechanism 6 includes an outer cylinder 61 which is rotatably mounted on the outer periphery of the inner cylinder 51 for exhaust gas, and the upper end of the outer cylinder 61 is connected with an upper cylinder 62, and the diameter of the upper cylinder 62 is larger than the diameter of the outer cylinder 61, and a drainage hole 63 is opened on the bottom wall of the upper cylinder 62.

[0055] By providing the drainage hole 63, water and dust can be effectively discharged when it rains.

[0056] A limit ring 64 is rotatably mounted on the outer cylinder 61 , a second connecting block 66 is fixedly mounted on the inner wall of the upper cylinder 62 , and an outer gear ring 67 is fixedly mounted on the lower end of the outer cylinder 61 .

[0057] A one-way ratchet 65 is fixedly mounted on the inner wall of the limiting ring 64 , and a one-way pawl 57 is fixedly mounted on the outer periphery of the inner cylinder 51 . The one-way pawl 57 is made of a flexible material and meshes with the one-way ratchet 65 .

[0058] When the inner cylinder 51 rotates, the outer cylinder 61 is fixed in position, and the one-way ratchet 65, the one-way pawl 57 and the limiting ring 64 rotate together. A scraper 68 is fixedly installed on the outer periphery of the limiting ring 64. The limiting ring 64 can drive the scraper 68 to slide on the upper end of the drainage hole 63, thereby clearing the accumulated water or blocked dust on the drainage hole 63, and the use effect is good.

[0059] By providing the one-way ratchet 65 and the one-way pawl 57 , the inner cylinder 51 can only rotate in one direction, thereby reducing accidental touching of the inner cylinder 51 by the outside world.

[0060] Example 5: Please refer to Figure 3-Figure 6 A second limiting mechanism 7 is arranged inside the mounting mechanism 6, and the second limiting mechanism 7 includes an arc-shaped plate 71 arranged at the upper end of the second conical cylinder 52, and a third connecting block 74 is arranged on one side of the outer periphery of the arc-shaped plate 71, and the third connecting block 74 is rotatably connected to the first connecting block 55. A first connecting rod 72 is also rotatably installed at one end of the outer side of the arc-shaped plate 71, and a second connecting rod 73 is rotatably installed at one end of the first connecting rod 72, and the second connecting rod 73 is rotatably connected to the second connecting block 66.

[0061] In the initial state, the six arc plates 71 are combined into a circular structure, and the circular structure is closed at the upper end of the inner cylinder 51, which further plays a sealing role for the discharge pipe body 21. When the pressure of the exhaust gas is too high, the airflow ejected from the first through hole 45 can continuously drive the inner cylinder 51 to rotate. With the cooperation of the arc plates 71, the first connecting rod 72, the first connecting block 55, the second connecting rod 73, and the second connecting block 66, the position of the outer cylinder 61 is fixed, and multiple arc plates 71 are unfolded at the same time. An opening appears in the center part of the multiple arc plates 71, and this opening is smaller than the opening of the second conical cylinder 52, which limits the particles flying upward. Therefore, the debris particles can only be discharged downward, which is suitable for the safe discharge of exhaust gas.

[0062] The center of the arc plate 71 is higher than the edge. A groove 75 is formed at the upper end of the arc plate 71 . A discharge port 76 communicating with the groove 75 is formed at one side of the arc plate 71 .

[0063] When the circular structure composed of multiple arc plates 71 is closed, rainwater or dust at the upper end will roll down along the inclined surface in the groove 75 of the arc plate 71, and finally be discharged from the discharge port 76. The position of the discharge port 76 corresponds to the drainage hole 63, which is more conducive to the discharge of other substances, reduces the accumulation of rainwater or dust on the arc plate 71 and enters the discharge pipe body 21, and further plays a role in safe discharge.

[0064] Example 6: Please refer to Figure 7-8 A driving mechanism 3 is also installed on the outside of the diffusion pipe mechanism 2. The driving mechanism 3 includes a placement frame 31 fixedly installed on the outer periphery of the diffusion pipe body 21. A bearing 32 is provided on the inner wall of the upper end of the placement frame 31. The upper end of the placement frame 31 is rotatably connected to the outer cylinder 61 through the bearing 32.

[0065] A mounting frame 33 is fixedly installed inside the placement frame 31 , a motor 34 is fixedly installed on the mounting frame 33 , a gear 35 is fixedly installed at the output end of the motor 34 , and the gear 35 is meshed and connected with the outer gear ring 67 .

[0066] The motor 34 can be turned on manually. After being turned on, the gear 35 rotates, that is, the outer gear ring 67 and the outer cylinder body 61 rotate, and the relative arc plates 71 are unfolded to reveal the second conical cylinder 52, which is convenient for manual cleaning.

[0067] Through the cooperation between the one-way ratchet 65 and the one-way pawl 57, the motor 34 can drive the inner cylinder 51 to rotate together during rotation, and can unilaterally drive the arc plate 71 to close, ensuring that the device can be opened and closed and is convenient for manual operation.

[0068] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0069] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
