2results about How to "Realize automatic temperature control" patented technology

The utility model discloses a negative pressure generating device which comprises a body and a holding portion connected to the body, an opening is formed in the top end of the body, a plurality of through holes are formed in the bottom end of the body, a wall face is connected between the opening and the through holes, and a cavity is formed in the wall face from the opening to the through holes. The body is also provided with a control module which is arranged outside the wall surface; the stock bin is of a cylindrical structure without a top cover; a plurality of small holes are formed in the cylinder bottom; a lifting module is arranged on the stock bin and connected with a driving mechanism so that the stock bin can ascend or descend in the cavity. The driving mechanism is connected with the control module; one end of the holding part is communicated with the bottom end of the body, and the other end of the holding part is a negative pressure acting opening. The negative pressure generating device is simple in structure and convenient to use, and the negative pressure acting opening in the bottom of the negative pressure generating device can be accurately matched with all parts of the body and is used for generating negative pressure on the parts of the body. The control module displaces the lifting module, so that the stock bin is close to or far away from the negative pressure acting opening, and automatic temperature control near the negative pressure acting opening is achieved.

The utility model belongs to building material production technical field especially for a kind of high-temperature baking forming device for producing perforated brick, including furnace body, conveying mechanism, temperature control system and mould assembly, furnace body is divided into preheating section, high-temperature baking section and cooling section along the direction of conveyance, each section is configured independent temperature control component;High-temperature baking section is equipped with angle-adjustable gas burner, mould adopts openwork heat conduction structure and cooperates automatic demoulding mechanism.The utility model, furnace body subsection design cooperates angle-adjustable burner, realizes the uniform heating of brick blank, improves finished product pass rate, and the flue gas waste heat is recycled, reduces energy consumption, energy saving and emission reduction, carborundum mould cooperates heat conduction hole and lubricating coating, improves heat conduction efficiency, prolongs service life, realizes the design of automatic temperature control and demoulding, production efficiency is high, and it is applicable to large-scale production.
