The utility model provides a high-frequency filter heat dissipation assembly. The high-frequency filter heat dissipation assembly comprises a filter body, wherein a heat dissipation block is mounted on the front side of the filter body; a heat dissipation substrate is arranged on one side, close to the filter body, of the heat dissipation block, and the heat dissipation substrates on the two sides are tightly attached to the two sides of the filter body; a heat dissipation assembly is arranged between the heat dissipation substrate and the heat dissipation block; a mounting groove is formed in the side, away from the filter body, of the heat dissipation block, a heat dissipation fan is mounted on the inner wall of the mounting groove, and a dismounting and mounting assembly is arranged between the heat dissipation fan and the heat dissipation block. The heat dissipation substrate is tightly attached to the filter body, so that the contact thermal resistance is effectively reduced, and the heat conduction efficiency is improved; the wave-shaped radiating fins are matched with the ventilation holes, so that the radiating area and the air circulation are increased; the air guiding system composed of the air guiding groove, the flow dividing block, the flow guiding block and the air guiding plate enables airflow generated by the cooling fan to accurately and efficiently act on the cooling fins, and compared with a traditional single cooling mode, the cooling efficiency is improved.

The invention discloses a thermophilic xylanase LD3-Xyn6 and an application of the thermophilic xylanase LD3-Xyn6. Belongs to the technical field of gene engineering. According to the invention, a brand new xylanase gene is identified and obtained from a metagenome of Yunnan Dali Jingu hot spring, and the recombinase is obtained through heterologous expression and purification. An enzymatic property characterization result shows that the optimum temperature of the enzyme is 85 DEG C, and the optimum pH value is 5.6; the half-life periods at 85 DEG C and 90 DEG C are 15 min and 10 min respectively, and excellent heat resistance and excellent temperature and pH stability are shown. In addition, K < + >, Ca < 2 + > and Mg < 2 + > have an activation effect on the enzyme activity. The xylanase can effectively degrade various natural xylans, and hydrolysates of the xylanase mainly comprise xylobiose and xylotetraose and are proved to be capable of remarkably promoting growth of lactococcus lactis. Therefore, the xylanase LD3-Xyn6 disclosed by the invention has a wide application prospect in the preparation of high-temperature-resistant feed additives and prebiotics.

A valve seat barrel is arranged in a valve seat cavity in a sealed and lifting mode, and the top of the valve seat barrel is connected with a control rod penetrating out of a cover body; according to the novel intelligent working full-automatic drain valve, the upper surface of a barrel bottom is connected with a valve seat barrel internally provided with a transition cavity, and the valve seat barrel is arranged in a valve seat cavity in a cover body in a sealing and lifting mode; a first through hole communicated with the transition cavity and a second through hole communicated with the working cavity are formed in the barrel bottom, and a third through hole and a fourth through hole are formed in the periphery and the top of the valve seat barrel respectively; the height of the inverted barrel can be controlled by a driver or automatically realized through buoyancy, and when the height is controlled by the driver, the opening and closing of the whole drain valve are efficient through the action relationship between the valve seat barrel and the valve seat cavity; when the buoyancy is automatically realized, the water vapor retained in the inverted barrel enables the inverted barrel to float upwards to generate sealing, and otherwise, if condensate water exists in the inverted barrel, the inverted barrel descends and the sealing is lost.
