Description

Technical Field

[0001] This utility model relates to the field of xanthate granulation technology, specifically to a device for reducing xanthate extrusion dust. Background Technology

[0002] Xanthates are the core collectors for sulfide mineral flotation. Their production process mainly includes the preparation of alkali powder → synthesis reaction → extrusion molding → drying → packaging. Among them, extrusion molding is a pre-granulation step (making the synthesized xanthate material into strips).

[0003] After synthesis, xanthate granules need to be granulated in an extruder. After granulation, they are discharged by a conveyor belt and sent to a drying pot. However, dust is easily generated before and after the extrusion process, so effective dust removal is required before and after granulation and extrusion. Therefore, a device to reduce dust during xanthate extrusion is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a device for reducing xanthate compression dust, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for reducing xanthate extrusion dust, comprising an extruder, a discharge pipe, a conveyor belt, an exhaust pipe, and a receiving hopper. An exhaust assembly is installed between the inlet pipe of the extruder and the discharge pipe that discharges material into the extruder. The exhaust assembly is connected to the exhaust pipe, which is located at the upper end of the conveyor belt. The conveyor belt is located at the lower end of the extruder where xanthate granules are extruded and transports the xanthate granules. The receiving hopper is located at the end of the conveyor belt for receiving xanthate granules for filling.

[0006] Preferably, the exhaust assembly includes a connecting pipe and a housing. The housing is installed at the opening of the inlet pipe, and the outlet pipe is installed on the housing. The inlet pipe and the outlet pipe are connected through the housing. The connecting pipe is connected between the housing and the exhaust pipe. A baffle plate is installed inside the housing corresponding to the upper end of the connecting pipe.

[0007] Preferably, a material guide plate is installed on the exhaust pipe at the point where the xanthium granules are extruded by the extruder, for blocking the xanthium granules extruded by the extruder.

[0008] Preferably, a guide plate is installed at the lower end of the part of the extruder that extrudes xanthium granules.

[0009] Preferably, the receiving hopper is equipped with a scraper for scraping the xanthate on the conveyor belt.

[0010] Preferably, a screen plate is installed on the inner bottom surface of the receiving hopper, and a guide hopper is installed at the bottom of the receiving hopper corresponding to the lower end of the screen plate.

[0011] Preferably, the exhaust pipe is provided at the upper end of the part of the extruder that produces xanthium granules and at the opening of the receiving hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: A device for reducing xanthate extrusion dust is provided by setting an exhaust component between the discharge pipe of the mixer and the feed pipe of the extruder. The exhaust pipe is connected to the absorption tower through a pipeline to allow the gas to be discharged, thereby accelerating the synthesis discharge speed and reducing dust during the material entering the mixer. The baffle plate set inside the exhaust component can prevent the material from being discharged into the connecting pipe and prevent it from entering the exhaust pipe. The material guide plate and the flow guide plate set can block and guide the strip-shaped material extruded by the extruder, so that it is aligned with the center of the conveyor belt, reducing dust during the material discharge process and preventing it from falling outside the conveyor belt. The scraper set at the discharge port of the conveyor belt reduces the amount of powder adhering to the conveyor belt during the production process, and the powder is scraped off in a concentrated manner to prevent the powder from scattering everywhere with the conveyor belt. The scraped powder falls into the receiving hopper, and the sieve plate and the guide hopper set in the receiving hopper can separate and collect the powder. Attached Figure Description
