This utility model provides an energy-saving dry ice manufacturing and feeding device, relating to the field of dry ice feeding devices. It includes a storage tank, a first pipe at the bottom of the tank, a heat exchanger at one end of the first pipe, a flow meter on the surface of the first pipe, a second pipe on the side of the heat exchanger, an exhaust gas pipe on the surface of the heat exchanger, and a dry ice manufacturing machine at one end of the second pipe. The exhaust gas pipe 5 recovers the exhaust gas emitted by the dry ice manufacturing machine 6 and guides it into the heat exchanger 3 to pre-cool carbon dioxide, reducing refrigeration energy consumption. A flow meter 17 accurately measures the carbon dioxide flow rate to avoid over-cooling, thereby significantly reducing energy consumption in the dry ice manufacturing process, improving production efficiency, and lowering production costs.

The utility model discloses a mechanical sealing device for side stirring, which comprises a shaft sleeve, a flange component and a positioning ring are arranged on the peripheral side of the shaft sleeve, fixing bolts are arranged on the flange component and the positioning ring, a cooling cylinder is arranged between the flange component and the positioning ring, and the flange component, the positioning ring and the cooling cylinder form a sealing cavity. A sealing cavity inlet is formed in the top of the positioning ring, a sealing cavity outlet is formed in the bottom of the flange assembly, a cooling cavity is formed in the cooling cylinder, a cooling cavity inlet is formed in the top of the cooling cylinder, and a cooling cavity outlet is formed in the top of the cooling cylinder; static rings are arranged on the two opposite sides of the flange assembly and the positioning ring, and a spring seat is installed on the peripheral side of the shaft sleeve. According to the utility model, through the arranged spring seat, the movable seat which is elastically matched with the two sides of the spring seat can drive the movable ring to move, so that the movable ring can meet the movement amount during the deformation of the stirring shaft, thereby reducing the influence of the extension of the stirring shaft or the middle sinking deformation on the mechanical seal, and prolonging the service life of the device.

The utility model discloses a thermosensitive developing gas phase cooling exhaust guide interface which comprises a joint structure, the bottom end of which is connected with an air inlet; the air outlet mechanism is connected to the top end of the connector structure; the two sides of the connector structure are each provided with two heat exchange connectors, and a one-way communication mechanism is connected between every two adjacent heat exchange connectors. The connector structure comprises a connector box, partition plates and a connecting pipe, the multiple partition plates are fixedly assembled in the connector box and used for partitioning the space of an inner cavity of the connector box, and the multiple partition plates are connected with the connecting pipe in a penetrating mode. According to the utility model, the arrangement mode that the joint structure is matched with the air outlet mechanism is utilized, and the temperature-sensitive color-changing coating is coated on the temperature-sensitive display tube, so that when hot air is exhausted, the color is changed along with the temperature rise, a dynamic warning effect on customers is achieved, personnel are effectively prevented from being scalded, and the temperature rise in a laboratory caused by direct heat emission is reduced; indoor heat management is effectively carried out, and energy is saved.
