Water vapor doping device

Abstract

The invention discloses a water vapor mixing device and aims at providing the water vapor mixing device which is low in investment, low in operation cost and durable in use. According to the technical scheme, the water vapor mixing device is characterized in that a circular rotary discharging hopper is additionally arranged in the portion between an upper feeding hopper and a lower receiving hopper, and the transverse periphery of the discharging hopper is composed of multiple solids and spaces with open outer edges, wherein the solids and the spaces are arranged at equal intervals, the upper edge and the lower edge of the peripheral rim are open, and the attached positions of the left edge and the right edge are solid; a vapor inlet pipe is mounted on the wall on one side; on the basis of the acting principle of the water vapor mixing device, when each space is rotated to the space of the upper feeding hopper in the operation process of the rotary discharging hopper, raw materials of the feeding hopper enter the space of the rotary discharging hopper and the space of the rotary discharging hopper is filled with the raw materials; when each space is continuously rotated to the lower edge space, the raw materials of the discharging hopper fall into the receiving hopper and are conveyed away; and when rotation is performed from bottom to top and the space of the receiving hopper communicates with an outlet of the vapor inlet pipe, the space is filled with water vapor, operation is continuously performed upwards for receiving the entering raw materials, and then air existing in gaps of the raw materials is squeezed out through the water vapor.

Description

technical field [0001] The present invention relates to a device for adding water vapor into raw materials, more precisely, more specifically, it is a small-scale mechanical device that injects water vapor into raw materials to improve plasticity and combine more tightly to provide favorable conditions for molding. Background technique [0002] In order to make the loose air-containing raw materials into compact billets or blocks with a certain shape, injecting water vapor into the raw materials is one of the effective methods in the production of bricks and tiles. The principle is that steam The existence of the air will remove the air and make the raw material warm up and improve the plasticity, but there are certain difficulties in adding water vapor to the raw material evenly, that is, it is generally impossible to do so, so it appears that the air in the raw material is drawn out by the operation of the vacuum pump. In order to improve the compactness of raw materials, ...

Problems solved by technology

[0004] Since the inner wall of the stirring tank in operation, the conical sleeve and the helical blade are easy to wear, especially the conical sleeve is subject to the friction of the raw material during the forward movement and the friction with the raw material during the rotation. Once the wear exceeds the limit, it will The channel changes from narrow to wide, which not only increases the amount of material supplied, but also makes it difficult to block the entry of rear air, making the vacuum chamber useless; at the same time, the extrusion volume of the lower spiral blade decreases accordingly, and one increase and one decrease will inevitably form raw materials in the vacuum chamber. If it is blocked due to stagnation, the vacuum pump will lose its function due to the blockage of the vacuum chamber, and the door of the vacuum chamber will be squeezed and forced to stop working.

Therefore, there are disadvantages such as large investment, high energy consumption, high operating cost and large amount of maintenance.
