Description

Technical Field

[0001] This utility model relates to the technical field of carbon black processing equipment, and in particular to a carbon black mixing device. Background Technology

[0002] In industries such as rubber and ink, carbon black mixing equipment is a core production device. Its internal lining directly affects the mixing quality and equipment life. The lining material must have high wear resistance, corrosion resistance and good thermal conductivity to resist long-term friction and chemical erosion of carbon black particles.

[0003] Currently, the lining structure of most carbon black mixing devices adopts a fixed installation, such as connecting to the cavity through welding or bolt fastening. Although this design ensures the stability of the lining during operation, it exposes significant drawbacks when wear and corrosion occur or when it is necessary to replace the lining with a different material to adapt to multi-variety production. The disassembly process is complicated. For example, welded linings need to be removed by destructive means such as cutting or mechanical knocking, which can easily damage the equipment base. Although bolt fastening is not destructive, it requires the removal of a large number of bolts, and the bolts are exposed to the high temperature and vibration environment of mixing for a long time, which can easily lead to rust and jamming, resulting in extremely low disassembly efficiency.

[0004] To address these shortcomings, we proposed a carbon black mixing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carbon black mixing device.

[0006] The purpose of this utility model is achieved through the following technical solution: a carbon black mixing device, including a shell and a support. A discharge pipe is welded to the lower surface of the shell, and a valve is installed on the surface of the discharge pipe. A stirring motor is fixed to the upper surface of the shell by bolts. A stirring paddle is installed at the output end of the stirring motor and extends through and into the interior of the shell. A slot frame is welded to the inner side of the shell. A locking strip is engaged with the slot frame, and an anti-loosening nut is screwed between the slot frame and the locking strip. A fixing pin is welded to the inner side of the slot frame. The surface of the locking strip has a locking hole for use with the anti-loosening nut and the fixing pin. The locking strip is welded to the outer side of the liner, and a sealing gasket is installed at the edge of the liner. The sealing gasket is made of fluororubber. The liner can be of various types, including a zirconia ceramic liner, a tungsten carbide alloy liner, and a copper-containing composite stainless steel liner.

[0007] Furthermore, the liner has an internal cavity, and a grid-type filter plate is welded inside the cavity. Fatty acid phase change capsules are arranged between the grid-type filter plates. The upper surface of the liner has a water inlet that runs through the cavity, and a cover is screwed onto the water inlet.

[0008] Furthermore, a lifting frame is welded to the upper surface of the cover, and a through hole for use with a stirring motor is opened on the upper surface of the lifting frame. The lower part of the lifting frame is connected to the telescopic end of the electric cylinder by bolts. The electric cylinder is fixed at the mounting base, and the mounting base is fixed to the outer side of the shell by bolts.

[0009] Furthermore, the shell is composed of a cylindrical cavity and a conical cavity, with the conical cavity welded to the bottom of the cylindrical cavity.

[0010] Furthermore, the lower surface of the bracket is provided with a threaded hole, and a lifting support foot is threadedly connected to the threaded hole.

[0011] Furthermore, an integrated controller is bolted to the lower surface of the bracket.

[0012] This utility model has the following advantages: In this invention, the inner lining is engaged by a slotted bracket and a clip, and secured by a fixing pin and an anti-loosening nut. This allows for the replacement of zirconia ceramic linings, tungsten carbide alloy linings, or copper-containing composite stainless steel linings for different types of carbon black particles without disassembling the housing. This reduces downtime for maintenance and improves production efficiency. The sealing gasket is made of fluororubber, which has excellent resistance to high and low temperatures and chemical corrosion, ensuring a good seal between the linings and preventing carbon black dust from penetrating.

[0013] In this invention, fatty acid phase change capsules are installed inside the lining cavity. Utilizing the solid-liquid phase change characteristics of fatty acid phase change materials, they absorb or release heat during the mixing process, maintaining a stable temperature inside the cavity, achieving passive temperature control, and reducing energy consumption. The grid-type filter fixes the phase change capsules to prevent them from moving inside the cavity, while ensuring uniform heat transfer and avoiding fluctuations in carbon black performance caused by local overheating or uneven temperature.

There are multiple types of inner liners 11, namely, zirconium oxide ceramic inner liner 11, tungsten carbide alloy inner liner 11, and copper-containing composite stainless steel inner liner 11.

[0023] In one embodiment, the inner liner 11 is engaged with the slot bracket 12 and the clip 13, and secured with a fixing pin and a lock nut. This allows for the replacement of the zirconia ceramic inner liner 11, tungsten carbide alloy inner liner 11, or copper-containing composite stainless steel inner liner 11 for different types of carbon black particles without disassembling the housing 1, thereby shortening downtime for maintenance and improving production efficiency.

[0025] In one embodiment, fatty acid phase change capsules 16 are provided in the cavity 14 of the liner 11. Utilizing the solid-liquid phase change characteristics of fatty acid phase change materials, they absorb or release heat during the mixing process to maintain a stable temperature inside the cavity, achieving passive temperature control and reducing energy consumption.
