Description

Rolling quartz sand coloring heating furnace

technical field

The utility model relates to the field of industrial heating and roasting stoves, in particular to a natural quartz sand rolling continuous coloring heating furnace.

Background technique

Colored quartz sand is divided into dyed colored sand, artificial colored sand, natural colored sand, non-fading colored sand, natural colored stone and dyed colored stone. Natural colored sand is limited by the ore, it is difficult to have better batch color stability after collection and crushing, and the color is limited by the color of the ore itself, most of them are relatively dull, so the selection of some colored sand colors is subject to greater influence. limits. Richer colors can be obtained by direct coloring with pigments, etc., but there is a problem that the color is difficult to adhere, and the color fastness, weather resistance, durability, acid and alkali resistance after coloring are not good, so it is difficult to meet the color requirements of quartz sand. Various needs.

Sintering coloring is a better way to obtain stable color fastness and various resistances for quartz sand coloring, but the current equipment is intermittent production, usually after adding toner, sintering glue and quartz sand, heating and roasting for a certain period of time before discharging . Only one batch of materials can be produced in one heating process, so there are problems such as small production batches, poor stability between batches, long production time, high energy consumption, and high pressure on production costs.

Utility model content

The purpose of this utility model is to provide a rolling type quartz sand coloring heating furnace to realize a continuous production mode, aiming to solve the existing intermittent quartz sand sintering and coloring problems of low production capacity, high energy consumption, and stability between batches Poor performance and high cost.

The purpose of this utility model is achieved by the following technical solutions:

Rolling quartz sand coloring heating furnace, including furnace, furnace, feed inlet and outlet, the bottom of the furnace is built with refractory bricks, and the furnace is lined with thermal insulation cotton. From the feed port to the discharge port, it is set from high to low. There are heating resistors in the furnace on both sides of the furnace. The feed port and discharge port of the furnace are supported by supporting wheels. Gears are arranged in the circumferential direction, and a transmission mechanism is provided at the discharge port end of the furnace, and the gears on the furnace are matched with the transmission mechanism.

The circumferential gear of the furnace is arranged on the outer periphery of the discharge port of the furnace. The transmission mechanism includes a motor, a transmission belt and a transmission gear. The motor drives the transmission gear through the transmission belt, and the transmission gear meshes with the gear on the furnace.

The top of the furnace is provided with a temperature-collecting thermocouple.

Compared with the current technology, the utility model adopts a horizontal furnace and gear transmission, and the mixed material is rotated by the transmission mechanism in the high-temperature furnace, mixed, heated and colored, and slowly pushed forward. It is colored after mixing and roasting, and then released from the discharge port. During this period, the materials will be continuously fed into the roasting furnace to realize the continuous production mode. The rolling continuous heating production is adopted as a whole, which solves the problems of low production capacity, high energy consumption, poor stability between batches and high cost of intermittent production. It can be equipped with an automatic speed regulator to adjust the roasting time and discharge speed of materials in the furnace according to the production process.
