Description

Technical Field

[0001] The utility model relates to the technical field of tire production auxiliary equipment, in particular to an automatic rapid cooling and weighing device for granulating masterbatch. Background Art

[0002] With the development of society, the series one-step mixing process has been widely promoted. The one-step mixing process uses two internal mixers plus an auxiliary mixing mill unit (the final mixing chemicals are added from the mixing mill) to achieve the goal of producing the final mixed rubber from the raw materials at one time, achieving the purpose of energy saving and efficiency improvement.

[0003] Since the final refined chemicals are added from the open mixing mill, and most of the final refined chemicals are a mixture of sulfur, accelerators, anti-scorching agents and other materials, all of which are powdered materials. When added from the open mixing mill, they are light and easy to fly, making them inconvenient to add. Therefore, the chemicals used need to be mixed and refined with a small amount of rubber and additives according to their types. The resulting granules are called granulation masterbatch.

[0004] The original weighing method was manual weighing. After granulation and pelletizing, talcum powder was blown in and transported through a conveying pipe. At the end of the conveying pipe, there was a soft connection, and an empty granulation basket was fixed below. The soft connection was held manually for manual weighing. When the weighed weight did not meet the requirements, the weight of the granulation had to be increased or decreased many times, which increased the labor intensity. After the granulation masterbatch was produced, the temperature was high and it was easy to stick. In order to prevent the granulation masterbatch from sticking, talcum powder was usually added during the weighing process. When weighing manually at close range, some talcum powder flew out and generated dust that was harmful to the human body. In addition, long-term exposure to various chemicals is not good for human health. Utility Model Content

[0018] The utility model is further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0019] Reference Figure 1-3 As shown, a granulation masterbatch automatic rapid cooling and weighing device comprises a vibration component, a cooling component and an automatic weighing component.

[0020] The vibration assembly includes a shell 1, a vibrating screen 4 and a conveyor belt 6. A feed port 2 and a dust removal device 3 are provided on the top of the shell 1. The vibrating screen 4 is horizontally mounted in the middle of the inner cavity of the shell 1, and a cleaning port 5 is provided on the upper side wall of the shell 1; the conveyor belt 6 is horizontally installed at the bottom of the inner cavity of the shell 1, and a discharge port 7 is provided at the bottom of the shell 1 on the rear side; the discharge port 7 is connected to the feeding port 13 of the cooling assembly tank 10.

[0021] In more detail, the vibration assembly also includes an induced draft fan 8. Interconnected perforated pipes 9 are installed on the inner wall of the shell 1 around the vibrating screen 4, on both sides of the conveyor belt 6 and on the front side. The induced draft fan 8 is installed on the outer wall of the shell 1 and is connected to the perforated pipes 9.

[0022] The cooling assembly includes a tank body 10, a stirring assembly and a cooler 11. A feeding port 13 and a dust removal device 3 are provided on the top of the tank body 10, and a discharge port 14 with a built-in butterfly valve 15 is provided on the bottom; the stirring assembly includes a hollow stirring shaft 16 and a driving assembly installed on the top of the tank body 10, the stirring shaft 16 is installed in the inner cavity of the tank body 10 for vertical rotation, and its upper end passes through the top plate of the tank body 10 and is transmission-connected with the driving assembly; a hollow spiral blade 17 is installed on the stirring shaft 16, and liquid slip rings 18 are installed on both the upper and lower ends of the stirring shaft 16, and the circulating water circuit 12 is connected through the two liquid slip rings 18; the circulating water circuit 12 is provided with a cooler 11, and the two liquid slip rings 18 are fixedly connected to the tank body 10 through a bracket, and the upper and lower ends of the spiral blade 17 are connected to the stirring shaft 16.

[0023] The automatic weighing assembly includes an automatic weighing device 23 , on which a hopper 24 is disposed. The hopper 24 is located directly below the discharge port 14 of the tank body 10 , has an opening at the top, and has an electrically controlled valve 25 disposed in the discharge port at the bottom.

[0024] The specific implementation is as follows:

[0025] After the granulation masterbatch is granulated, it is transported to the shell 1 through the feed port 2, and first falls on the upper vibration screen 4. The granules are vibrated and separated on the vibration screen 4. The granules smaller than the sieve holes fall on the conveyor belt 6 of the lower layer, and are transported by the conveyor belt 6 and enter the cooling component through the discharge port 7; the granules larger than the sieve holes are retained on the vibration screen 4. After working for a period of time, the cleaning port 5 can be opened to clean them. The induced draft fan 8 is installed outside the shell 1. The induced draft fan 8 performs preliminary air cooling and cooling on the granulation masterbatch on the vibration screen 4 and the conveyor belt 6 through the perforated pipeline 9 to reduce adhesion. The dust removal device 3 on the top of the shell 1 can absorb the dust generated during the vibration of the granulation masterbatch to reduce environmental pollution.

[0026] After the granulation masterbatch enters the tank body 10 of the cooling component, the driving component drives the stirring shaft 16 to rotate, thereby driving the spiral blade 17 to stir the granulation masterbatch; at the same time, the cooler 11 passes cooling water to the stirring shaft 16 and the spiral blade 17 through the circulating water path 12 to realize the cooling water circulation, thereby achieving the purpose of further cooling the granulation masterbatch.

[0027] When the empty basket reaches just below the hopper 24, the controller controls the butterfly valve 15 at the bottom of the tank body 10 to open, and the granulation masterbatch enters the hopper 24. When the automatic weigher 23 detects that the granulation masterbatch in the hopper 24 reaches the set weighing weight, the controller controls the butterfly valve 15 to close and the electric control valve 25 to open, and the weighed granulation masterbatch falls into the empty basket below through the discharge port. When all the materials in the hopper 24 are added, the electric control valve 25 is closed, waiting for the arrival of the next empty basket.

[0028] The device performs two-stage cooling of the granulation masterbatch through a vibration component and a cooling component, thereby solving the problem of easy adhesion of the granulation masterbatch due to high temperature after output, thereby reducing the use of talcum powder and improving on-site environmental hygiene; the granulation masterbatch vibrates on the vibration screen 4, which can also reduce the problem of mutual adhesion; automatic weighing can be achieved through the cooperation of the cooling component and the automatic weighing component, solving the problem of inaccurate manual weighing, reducing the labor intensity of workers and improving weighing efficiency.
