Description

Technical Field

[0002] The waste rubber cracking reaction unit is a technical equipment specially designed to process waste rubber and convert it into useful products through thermochemical processes. Usually, a reactor is used for cracking in order to achieve the recycling of resources, reduce environmental pollution, and extract economic value from it.

[0003] When the waste rubber cracking reaction device is in use, the treated waste rubber is poured into the reactor through the feed pipe, and the reactor is started to work, so that the heating device inside the reactor raises the temperature to the high temperature required for cracking (usually 400°C to 550°C) in advance, so that the incoming material begins to break, and after the work is completed, it is discharged through the discharge pipe and exhaust pipe.

[0004] In the actual use of the prior art, since the processed waste rubber is of different sizes, it takes a lot of time to enter the reactor for cracking, thereby reducing production efficiency. Therefore, a waste rubber cracking reaction device is proposed. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the first embodiment of the utility model, and provides a waste rubber cracking reaction device, including a reactor 1 and a feed pipe 101, the outer surface of the reactor 1 is provided with the feed pipe 101, and the outer surface of the feed pipe 101 is provided with a crushing component 2.

[0032] Specifically, the crushing assembly 2 includes a support plate 201 fixedly mounted on the outer surface of the feed pipe 101, a motor 202 is fixedly connected to the side of the support plate 201, a rotating rod 203 is provided at the output shaft end of the motor 202 and the inside of the feed pipe 101, crushing blades 204 are fixedly connected to the outer surfaces of the two rotating rods 203, gears 205 are fixedly connected to the outer surfaces of the two rotating rods 203, and the two gears 205 are meshed with each other.

[0033] Further, the motor 202 is started to drive one of the rotating rods 203 to rotate. When the rotating rod 203 moves, the gear 205 is driven to rotate. Because the two gears 205 are meshed, when the gear 205 rotates, the two rotating rods 203 are driven to rotate in opposite directions, and the crushing blade 204 is further driven to rotate, so that the crushing blade 204 crushes the waste rubber, avoiding a long cracking time due to the different sizes of the waste rubber, thereby performing secondary crushing on the waste rubber, so as to improve the cracking efficiency and production speed.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. A groove 102 is opened on the side of the reactor 1, a sealing cover 103 is provided on the outer surface of the groove 102, and a sealing cover opening and closing assembly 3 is provided on the outer surface of the sealing cover 103.

[0036] Specifically, the sealing cover opening and closing assembly 3 includes two side plates 301 fixedly installed on the outer surface of the reactor 1, the sides of the two side plates 301 are hinged with electric push rods 302, the sides of the electric push rods 302 are hinged with connecting plates 303, the sides of the two connecting plates 303 are fixedly connected to the outer surface of the sealing cover 103, the outer surface of the reactor 1 is fixedly connected with two fixed plates 305, a guide rod 306 is rotatably connected between the two fixed plates 305, the outer surface of the guide rod 306 is fixedly connected with a connecting block 307, and the side of the connecting block 307 is fixedly connected to the outer surface of the sealing cover 103.

[0037] Furthermore, the two electric push rods 302 are started to work, so that the electric push rods 302 drive the sealing cover 103 to rotate through the connecting plate 303. When the connecting plate 303 moves, it pulls the sealing cover 103 to rotate along the trajectory of the guide rod 306, so as to open the reactor 1, thereby facilitating the staff to enter the reactor 1 for cleaning, inspection or maintenance work.

[0038] Working principle: When in use, pour the processed waste rubber into the feed pipe 101. At this time, start the motor 202 to drive one of the rotating rods 203 to rotate. When the rotating rod 203 moves, it will drive the gear 205 to rotate. Because the two gears 205 are meshed, when the gear 205 rotates, it will drive the two rotating rods 203 to rotate in opposite directions, and further drive the crushing blade 204 to rotate, so that the crushing blade 204 crushes the waste rubber to avoid the long cracking time due to the different sizes of the waste rubber, thereby performing secondary crushing on the waste rubber to improve the cracking efficiency and production speed, and then start the reactor 1 to work. Since the specific structure and working principle of the reactor 1 are the existing technology well known to the staff in this field, they will not be elaborated here, so that the reactor 1 completes the reaction work on the waste rubber.

[0039] When the inner wall of the reactor 1 needs to be cleaned or maintained, the staff starts the two electric push rods 302 to work, so that the electric push rods 302 drive the sealing cover 103 to rotate through the connecting plate 303. When the connecting plate 303 moves, it pulls the sealing cover 103 to rotate along the trajectory of the guide rod 306 to open the reactor 1, thereby facilitating the staff to enter the reactor 1 for cleaning, inspection or maintenance. The sealing ring 304 between the sealing cover 103 and the groove 102 can enhance the sealing of the connection to prevent gas or liquid leakage, otherwise it can be closed.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
