[0002] As an important chemical raw material, carbon black is widely used in rubber, plastic, coating, ink and other industries. Its performance directly affects the physical properties and durability of the products. However, due to its tiny particle size and high aggregation, carbon black powder is not only prone to dust pollution during storage and transportation, but also difficult to disperse evenly when used directly, affecting the quality of the product. Therefore, carbon black granulation technology has become a key link in improving its application performance and processing convenience.

[0003] In the existing granulation dryer, in order to ensure the safety of equipment granulation during the carbon black drying process, it is usually necessary to control the dust concentration within an appropriate threshold value.

When the dust concentration inside the equipment is too high, the purpose of dust concentration control is achieved through shutdown protection and related measures such as introducing fresh air. In this process, the dust cannot be discharged from the equipment in a timely and rapid manner.

The left output shaft end of the first motor 109 passes through the drying chamber 103 and is fixedly connected to a first spiral conveying frame 110. The first spiral conveying frame 110 is rotatably connected to the frame 101. A penetrating air hole is opened on the conveying wall of the first spiral conveying frame 110. A stirring blade 1101 is fixedly welded to the side wall of the left side of the first spiral conveying frame 110. The first spiral conveying frame 110 is longer than the drying chamber 103 and is used to convey the carbon black raw material into the first rotating cylinder 105.

The upper and lower side walls of the frame 101 are respectively fixedly connected with a heating furnace 112, and an exhaust assembly is arranged on the left side of the frame 101.

[0036] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the exhaust assembly also includes an exhaust frame 201, which is slidably connected to the upper side wall and the lower side wall on the left side of the frame 101, and a number of air inlets are evenly distributed on the circumference of the side wall of the exhaust frame 201 to accelerate the discharge of exhaust gas. A sliding exhaust pipe 202 is fixedly connected between the exhaust frames 201, and a fixed pipe 203 is slidably sleeved on the left side of the sliding exhaust pipe 202. A cylinder 204 is fixedly installed on the left side of the middle of the frame 101, and a pull rod 205 is fixedly connected to the telescopic rod of the cylinder 204, and the pull rod 205 is fixedly connected to the sliding exhaust pipe 202. Concentration sensors 206 are fixedly connected to the upper and lower layers of the frame 101, and the concentration sensor 206 is electrically connected to the cylinder 204 through a control module.

[0037] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, a nitrogen pipe 301 is also included. The nitrogen pipe 301 is fixedly connected to the upper side wall and the lower side wall on the right side of the frame 101. The air inlet of the nitrogen pipe 301 is directly opposite to the air outlet of the exhaust frame 201, which is used to discharge dust in time. The nitrogen pipe 301 is fixedly connected to a valve 302, and the valve 302 is movably connected to the pull rod 205.

[0038] like Figure 1 , Figure 2 and Fig.11 As shown, it also includes a second motor 401, which is fixedly connected to the upper side wall and the lower side wall of the right rear part of the frame 101 respectively, and the output shaft end of the second motor 401 is fixedly connected to the first conveying roller 402, and the first rotating cylinder 105 and the second rotating cylinder 107 are both fixedly connected to two second conveying rollers 403, and the second conveying rollers 403 are in contact with the first conveying rollers 402.

[0039] like Figure 1 , Figure 2 , Fig.12 and Fig.13 As shown, a third motor 501 is also included. The third motor 501 is fixedly connected to the side wall on the right side of the connecting tube 106. A third spiral conveying frame 502 is rotatably connected in the connecting tube 106. The third spiral conveying frame 502 is fixedly connected to the output shaft on the left side of the third motor 501.

[0040] First, connect the left end of the fixed tube 203 to the fan, and connect the other side of the nitrogen tube 301 to the nitrogen delivery pipeline. Then, the carbon black raw material enters the drying chamber 103 through the feed port 102, and the heating furnaces 112 on the upper and lower sides of the frame 101 are started. The heating furnaces 112 heat the first rotating cylinder 105 and the drying chamber 103, thereby drying the carbon black raw material and removing the moisture inside the carbon black raw material. Then, start the first motor 109, and the first motor 109 drives the first spiral conveyor 110 to rotate counterclockwise, so as to slowly push the carbon black raw material in the drying chamber 103 to the left, and the hot air is transported to the wall through the first spiral conveyor 110. The carbon black raw material between the drying chamber 103 and the first spiral conveyor 110 is initially dried. At the same time, in the process of the first spiral conveyor 110 conveying the carbon black raw material to the left, the stirring blade 1101 welded on the side wall of the first spiral conveyor 110 turns and stirs the carbon black raw material to accelerate the drying of the carbon black raw material. In the process of the stirring blade 1101 turning, the agglomerated carbon black raw material is broken up, so that the carbon black raw material is evenly dried. The dust generated during the drying is then discharged through the connecting cylinder 104. The preliminarily dried carbon black raw material enters the first rotating cylinder 105, and then the carbon black raw material is started. The second motor 401 is located on the upper and lower sides of the frame 101. The output shaft of the second motor 401 rotates counterclockwise to drive the first conveying roller 402 to rotate, and then drives the second conveying roller 403, the first rotating cylinder 105, the second rotating cylinder 107 and the second spiral conveying frame 111 to rotate clockwise, pushing the carbon black raw material dropped into the first rotating cylinder 105 to the right. In the process of moving the carbon black raw material to the right by the second spiral conveying frame 111, the carbon black raw material is rolled and dried, and carbon black particles are gradually formed while rolling. Subsequently, the granulated carbon black raw material is transported to the connecting pipe 106, and the third motor 501 is started. The third motor 501 drives the third spiral conveyor frame 502 to rotate counterclockwise, and conveys the carbon black particles entering the connecting pipe 106 to the left. During the conveying process, the carbon black particles are subjected to secondary granulation. Then, the carbon black particles are guided by the connecting pipe 106 and the unloading plate 108 to enter the second rotating cylinder 107 for carbonization, thereby further improving the quality of the carbon black particles. Then, the carbonized carbon black particles are conveyed to the right through the second spiral conveyor frame 111 in the second rotating cylinder 107. During the conveying process, the carbon black particles are finally shaped. The shaped carbon black particles are discharged through the unloading port on the right side of the frame 101, thereby completing the entire granulation process.

[0041] In order to prevent the first rotating drum 105 and the second rotating drum 107 from having too high dust concentration when performing granulation work, resulting in excessive impurities in the product quality affecting the purity of the carbon black particles, and too high dust concentration will cause a safety hazard of dust explosion, during the carbon black drying and carbonization process, when the concentration sensor 206 detects that the dust concentration inside the first rotating drum 105 or the second rotating drum 107 exceeds the safety threshold, an electrical signal is sent out, and after receiving the electrical signal, the control module controls the cylinder 204 to extend, driving the pull rod 205 to move to the right, thereby driving the sliding exhaust pipe 202 and the exhaust frame 201 to move to the right, so that the exhaust frame 201 is separated from the double-layer annular protrusion of the frame 101, the exhaust frame 201 is opened, and then the external fan is started to quickly discharge the dust in the first rotating drum 105 and the second rotating drum 107. During the movement of the pull rod 205 to the right, the valve 302 is pushed to rotate and open, and the nitrogen enters the first rotating cylinder 105 and the second rotating cylinder 107 through the nitrogen pipe 301, so that the environment in the cylinder is further stabilized. When the concentration sensor 206 detects that the dust concentration in the first rotating cylinder 105 and the second rotating cylinder 107 is reduced to a safe threshold, an electrical signal is sent out. After receiving the electrical signal, the control module controls the cylinder 204 to shrink and reset, thereby driving the pull rod 205 to move to the left and reset, and then controlling the exhaust frame 201 and the sliding exhaust pipe 202 to move to the left, so that the exhaust frame 201 is re-fitted with the double-layer annular protrusion of the frame 101, and the exhaust frame 201 is reclosed. During the movement of the pull rod 205 to the left, the valve 302 is driven to rotate, thereby closing the valve 302 and stopping the nitrogen supply.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
