Description

Technical Field

[0001] The invention relates to a solid waste treatment technology, in particular to a solid waste treatment device used for screening p-phenylenediisocyanate. Background Art

[0002] 1,4-Phenylene diisocyanate (1,4-Phenylene diisocyanate) is an aromatic diisocyanate chemical substance that appears as white to pale yellow crystals at room temperature. It is flammable and corrosive, and easily polymerizes when exposed to light, moisture, or contact with amines and alcohols. Its decomposition products contain toxic gases such as carbon monoxide and hydrogen cyanide.

[0003] This substance can cause allergies or burns to the human body through inhalation, ingestion or skin contact. Self-contained breathing apparatus, goggles and protective gloves must be worn when handling. Storage must be sealed in an inert environment away from light and heat sources. In case of leakage, it must be collected with non-sparking tools and adsorbed with dry lime. Transportation must comply with UN 2811 dangerous goods regulations. Mixing with oxidants and alkalis is strictly prohibited. Vehicles must be equipped with fire retardants and emergency equipment.

[0004] The unqualified solid waste generated after screening of phenylenediisocyanate needs to be treated or recycled. Due to the chemical toxicity of phenylenediisocyanate, it needs to be treated by a solidification device. The usual treatment method is to add solidifying materials (such as cement, lime, clay, etc.) to wrap or fix the toxic substances in a solid structure, which can reduce the mobility and permeability of the toxic substances. Therefore, a fixed waste treatment device is needed. Summary of the Invention

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

The exhaust mechanism 8 is equipped with an exhaust pipe 9, a mounting assembly 10, a sensing assembly 11, and a sealing member 12.

[0045] A processing cylinder 2 is provided in the middle of the upper end of the fixed frame 1, a stirring mechanism 3 is provided in the middle of the processing cylinder 2, a driving mechanism 4 and a discharge mechanism 5 are provided at the lower end of the processing cylinder 2, and a feeding port 7 and an air inlet pipe 6 are provided on the outside of the processing cylinder 2.

The feeding port 7 is used to add materials to be processed, and the air inlet pipe 6 is used to introduce air into the interior to dilute the toxic gas generated when the internal materials are mixed, and the gas is discharged from the processing cylinder 2 through the exhaust mechanism 8.

[0046] The processing cylinder 2 is installed at the upper end of the fixed frame 1, and the driving mechanism 4 is arranged at the lower end of the processing cylinder 2 and on the fixed frame 1. The stirring mechanism 3 is arranged in the middle of the processing cylinder 2. The stirring mechanism 3 is driven by the driving mechanism 4 to rotate in the processing cylinder 2. The discharge mechanism 5 can be used to cooperate with the stirring mechanism 3 to discharge the material in the processing cylinder 2.

[0047] A first motor 13 and a second motor 14 are provided in the driving mechanism 4, and a first rotating shaft 15 and a second rotating shaft 16 are provided in the middle of the processing cylinder 2. The first rotating shaft 15 is connected to the first motor 13, and the second rotating shaft 16 is connected to the second motor 14. The second rotating shaft 16 is in the middle of the first rotating shaft 15, so that the first rotating shaft 15 and the second rotating shaft 16 can rotate towards or in opposite directions.

[0048] The stirring mechanism 3 is provided with a crossbeam 17, one end of which is provided with a connecting rod 18, on which are mounted two first stirring plates 19. A connecting rod 18 is also provided at the other end of the crossbeam 17, and a second stirring plate 20 is provided at an angle at its lower end. Furthermore, a support rod 21 is provided at the other end of the crossbeam 17, on which a third stirring plate 22 is provided. An extension beam 23 is provided in the middle of the crossbeam 17, and a rotatable stirring member 24 is provided at its lower end. A first gear 25 is provided at the upper end of the stirring member 24, and a second gear 26 is provided on the second rotating shaft 16, which cooperates with the first gear 25. The first gear 25 and the second gear 26 can be connected by a belt or chain, so that the stirring member 24 can be driven to rotate by the second motor 14.

[0049] A housing 27 that can rotate with the crossbeam 17 is provided on the crossbeam 17 . A cover plate (not shown in the figure) can be provided outside the housing 27 . The first gear 25 and the second gear 26 are provided in the housing 27 .

[0050] The discharge mechanism 5 is provided with a fixing member 28, a discharge member 29, and a cylinder 30. One end of the cylinder 30 is hinged to the outer wall of the treatment barrel 2 via a hinge seat 31, and the other end can extend. One end of a push rod 32 is hinged to the discharge member 29. The middle of the discharge member 29 is hinged to the fixing member 28, so that when the cylinder 30 pushes the push rod 32, the discharge member 29 can be kept rotating around the hinged portion of the fixing member 28. A supporting plate 33 for the treatment barrel 2 is provided at the lower end of the fixing member 28, and a guide plate 34 is provided at the lower end of the supporting plate 33 to guide the discharge of the material.

[0051] At the same time, the remaining structures of the present application, such as the stirring mechanism 3, the driving mechanism 4, the discharging mechanism 5, etc., can also refer to the structures of the prior art, so they will not be elaborated in detail here.

[0052] The exhaust pipe 9 is used to discharge the gas inside the treatment cylinder 2. A filter 35 is provided in the middle of the exhaust pipe 9. The filter 35 is used to filter dust so that the gas can pass through the filter 35. The seal 12 is used to fix the filter 35 and to seal the exhaust pipe 9.

[0053] Exhaust pipe 9 consists of a connecting pipe 36, a first branch pipe 37, and a second branch pipe 38. First branch pipe 37 is connected to treatment cylinder 2. Connecting pipe 36 connects first branch pipe 37 and second branch pipe 38. Second branch pipe 38 is used to connect to the air purification equipment. A support edge 39 is provided in the middle of connecting pipe 36. Support edge 39 is used to support filter element 35. A gas passage area 40 is formed in the middle of support edge 39. An opening 41 is provided on one side of connecting pipe 36. Opening 41 cooperates with sealing element 12 to seal and is used for mounting filter element 35. A mounting plate 118 is also provided on the outer wall of connecting pipe 36. A gas detector can be installed on mounting plate 118 to assist in monitoring gas leaks.

[0054] The exterior of the exhaust pipe 9 is provided with a mounting assembly 10, a sensing assembly 11, and a seal 12, which together form the exhaust mechanism 8. The seal 12 is used to seal the filter element 35 within the exhaust pipe 9, the mounting assembly 10 is used to limit the position of the seal 12, and the sensing assembly 11 is used to monitor changes in the force applied to the seal 12. When the air pressure inside the treatment cylinder 2 increases, air leakage may occur at the contact portion between the seal 12 and the exhaust pipe 9. The gas pushes the deformed portion 42 of the seal 12 to be stretched, thereby pushing the upper end of the seal 43, thereby forming a gap between the seal 43 and the exhaust pipe 9. When the deformable part 42 is pulled by force, the deformable part 42 pulls the sliding part 44, keeping the sliding part 44 applying pressure to the pressure sensor 45, so that the value of the pressure sensor 45 increases, and the pressure sensor 45 transmits the electrical signal to the controller, and promptly issues an alarm signal to facilitate timely processing by the staff, thereby avoiding the risk of toxic gas leakage, protecting the personal safety of the staff, and providing a comfortable working environment.

[0055] Example 1

[0056] Seal 12 consists of a sealing portion 43 and a deformable portion 42. Sealing portion 43 is inserted into mounting assembly 10, while the upper end of deformable portion 42 remains connected to sensing assembly 11. Sealing portion 43 is a plate-like structure, while deformable portion 42 is a sheet-like structure. Seal 12 is made of rubber material and deforms under load, effectively sealing against exhaust pipe 9.

[0057] Since the deformable portion 42 is a sheet-like structure, it can be stretched by force to generate elastic force, while the sealing portion 43 is thicker and is not easily stretched.

[0058] At the same time, the upper end of the deformed portion 42 is rolled up to form a winding section 46, and the end of the winding section 46 is provided with a retaining body 47 that cooperates with the sliding member 44. The winding section 46 is wound on the winding end 48 and then connected to the sliding member 44 through the retaining body 47.

[0059] A reinforcing plate 49 is positioned in the center of the sealing portion 43. A stopper 50 is positioned on one side of the lower end of the reinforcing plate 49, and a symmetrical positioning block 51 is positioned on the other side. The stopper 50 is provided with a guiding arc 52 and a guiding slope 53. The guiding slope 53 guides the insertion of the seal 12, while the guiding arc 52 maintains contact with the second arc segment 54, thereby retaining the seal 12 in position. The positioning block 51 is provided with a guiding slope 55, which guides the insertion of the seal 12 and limits the position of the seal 12 through the cooperation of the positioning block 51 and the positioning groove 56.

[0060] The lower end of the seal 12 forms an insertion end 57 , and the lower end of the reinforcing plate 49 forms a tip 58 . The insertion end 57 is inserted into the insertion area 59 to push the first limiting arm 60 and the second limiting arm 61 .

[0061] Example 2

[0062] The mounting assembly 10 is provided with a base plate 62, a baffle 63, a first limiting arm 60 and a second limiting arm 61. The baffle 63 and the first limiting arm 60 are arranged on the base plate 62, and the second limiting arm 61 is arranged on the baffle 63, and the first limiting arm 60 and the second limiting arm 61 are kept relatively arranged, and an insertion area 59 for inserting the seal 12 is formed between the first limiting arm 60 and the second limiting arm 61.

[0063] The first limiting arm 60 is composed, from top to bottom, of a first vertical section 64, an inclined section 65, a second vertical section 66, a guide section 67, and a third vertical section 68. The third vertical section 68 is connected to the base plate 62. The first limiting arm 60 is provided with a positioning groove 56 that cooperates with the positioning block 51. The first vertical section 64 is not located on the same plane as the second and third vertical sections 66, 68, but maintains contact with the outer wall of the exhaust pipe 9. The second and third vertical sections 66, 68 are located on the same plane.

[0064] The guide section 67 is arranged in an arc shape, and a first arcuate surface 69 and a second arcuate surface 70 are formed on the guide section 67. The first arcuate surface 69 is connected to the second vertical section 66, and the second arcuate surface 70 is connected to the third vertical section 68. The inner diameter of the second arcuate surface 70 is smaller than the inner diameter of the first arcuate surface 69. Since the inner diameter of the first arcuate surface 69 is larger and the inner diameter of the second arcuate surface 70 is smaller, the lower end of the seal 12 can be better guided, and the insertion of the seal 12 can be facilitated.

[0065] The second limiting arm 61 is composed of a first arc segment 71, a guide segment 72, a second arc segment 54, a contact segment 73, a third arc segment 74 and an interference segment 75. The first arc segment 71 connects the guide segment 72 with the baffle 63. The guide segment 72 is provided with symmetrically arranged stamping protrusions 76. The rear end of the stamping protrusions 76 forms a stamping groove 77. The stamping protrusions 76 can contact the seal 12 and cooperate with the second arc segment 54 to apply pressure to the seal 12 so that it is clamped in the insertion area 59.

[0066] A first elastic region 78 is formed between the guide segment 72 and the contact segment 73 , a second elastic region 79 is formed between the contact segment 73 and the baffle 63 , and the third arc segment 74 is in tangential contact with the baffle 63 .

[0067] A punched hole 80 is provided in the center of the guide section 72, and an elastic tongue 81 is disposed within the punched hole 80. The elastic tongue 81 comprises an extension section 82, a fourth arcuate section 83, a support section 84, a fifth arcuate section 85, and a push section 86. The fourth arcuate section 83 is disposed within the insertion region 59, the fifth arcuate section 85 is in tangential contact with the baffle 63, and the push section 86 is in contact with the abutment section 75.

[0068] When the seal 12 is not inserted into the insertion area 59, the minimum width of the insertion area 59 is smaller than the thickness of the seal 12. A gap is maintained between the pushing section 86 and the interference section 75. When the seal 12 is inserted into the insertion area 59, the seal 12 can push the elastic tongue 81, thereby maintaining the pushing section 86 on the elastic tongue 81 in contact with the interference section 75, and pushing the interference section 75 to slightly deform under force, bringing it closer to the guide section 72.

[0069] When the seal 12 is inserted into the insertion area 59, the first limiting arm 60 cooperates with the stamped protrusion 76 on the second limiting arm 61, the second arcuate segment 54, and the fourth arcuate segment 83 on the elastic tongue 81 to push the seal 12, so that the seal 12 remains force-restricted within the insertion area 59. Since the lower end of the seal 12 remains within the insertion area 59, the upper end of the seal 12 is not subjected to a large clamping force. When the air pressure in the exhaust pipe 9 is high and a gas leak occurs, the upper end of the seal 12 is pushed, keeping the deformable portion 42 stretched. The deformation causes the retaining body 47 to pull the sliding member 44, which then applies pressure to the pressure sensor 45.

[0070] Example 3

[0071] The sensing component 11 is provided with a fixed seat 87, a sliding member 44, a pressure sensor 45, an adjusting member 88, a first pressure member 89 and a second pressure member 90. The first pressure member 89 and the second pressure member 90 are hinged on the fixed seat 87 through a hinge rod 91. The adjusting member 88 is kept in contact with the second pressure member 90 by a spring 92. The deformation part 42 is kept connected to the sliding member 44. The pressure sensor 45 is arranged between the first pressure member 89 and the sliding member 44.

[0072] The sliding member 44 is composed of a first sliding part 93, a second sliding part 94 and an inclined part 95 for connecting the first sliding part 93 and the second sliding part 94. An active area 96 is formed between the first sliding part 93 and the second sliding part 94. An opening 41 on one side of the active area 96 forms a active opening 97. The width of the active opening 97 is smaller than the diameter of the retaining body 47, so that the retaining body 47 cannot detach from the active opening 97.

[0073] The first pressure member 89 is composed of a first hinged body 98 and a first extension 99. The second pressure member 90 is composed of a second hinged body 100 and a second extension 101. The center of the first hinged body 98 forms a receiving opening 102 for accommodating the second pressure member 90. The first extension 99 maintains contact with the pressure sensor 45. The pressure sensor 45 is provided with an arcuate opening 103 that cooperates with the first extension 99.

[0074] The fixed base 87 is provided with symmetrically arranged hinge blocks 104, each of which has a strip-shaped hole 105, into which the hinge rod 91 is disposed. The fixed base 87 is also provided with a coiling end 48 and a fixed end 106, with a placement area 107 formed between the coiling end 48 and the fixed end 106. The lower end of the coiling end 48 forms a sliding area 108 for the sliding member 44 and the pressure sensor 45. The fixed base 87 is provided with a sliding groove 109, and the exhaust pipe 9 is provided with a fixing post 110 that cooperates with the fixed base 87. The fixing post 110 is provided with a sliding portion 111 that cooperates with the sliding groove 109.

[0075] Adjustment member 88 comprises a first rod 112, a pusher 113, and a second rod 114. A spring 92 is sleeved onto second rod 114, maintaining the lower end of spring 92 on second pressure member 90. First rod 112 is provided with a threaded portion 115 and symmetrically arranged cut surfaces 116. Fixed seat 87 is provided with a threaded hole 117 that mates with threaded portion 115. Rotating adjustment member 88 changes the distance between second rod 114 and second pressure member 90, thereby changing the compression value of spring 92. This changes the external force applied by slider 44 to pressure sensor 45 and first pressure member 89, which can be monitored via pressure sensor 45. Rotating adjustment member 88 monitors the opening angle of seal 12. The greater the compression of spring 92, the more accurate its detection of the opening angle of seal 12.

[0076] The greater the compression value of the spring 92, the greater the thrust of the first pressure member 89 on the pressure sensor 45. Therefore, when the sliding member 44 is slightly pulled by the deformation portion 42, the monitoring value is more accurate. Conversely, the smaller the push of the first pressure member 89 on the pressure sensor 45 is, the less reverse force will be provided to the pressure sensor 45, so that the sliding member 44 can push the pressure sensor 45, making the pressure sensor 45 unable to move or reducing the pressure value of the sliding member 44 on the pressure sensor 45, resulting in inaccurate monitoring, and thus the pressure sensor 45 cannot issue an electrical signal alarm.

[0077] The present application adds solidifying material to the unqualified solid waste produced after screening of p-phenylenediisocyanate, and then stirs it through a stirring mechanism 3, so as to keep the solidifying material fully wrapped around the p-phenylenediisocyanate, shorten the wrapping time, improve the wrapping efficiency, thereby reducing the toxicity of p-phenylenediisocyanate and facilitating subsequent recovery and treatment. At the same time, the present application also provides an exhaust mechanism 8 on the outside of the treatment tube 2, which can discharge and dilute the toxic gas generated by the p-phenylenediisocyanate when it is stirred with the solidifying material, and filter the dust through the filter element 35. The provided sensing component 11, mounting component 10 and sealing component 12 can seal the exhaust pipe 9. When the internal air pressure of the treatment tube 2 is high, an automatic alarm can be realized to avoid the leakage of toxic gas and cause harm to the staff.
