The closed pelletization system for liquid copper matte has advantages of high safety factor, small pollution, long service life and high production efficiency.

The invention discloses an LED projection lamp provided with a heat dissipation device, which comprises an LED projection lamp and a base provided with an accommodating cavity inside; Connected first support tube and second support tube; the LED floodlight includes a lamp body with a heat dissipation cavity inside and an LED floodlight panel arranged on the lamp body; the left and right sides of the lamp body respectively hinged on the first support tube and the second support tube, and both the first support tube and the second support tube communicate with the heat dissipation cavity; The cooling liquid in the housing chamber is sent to the cooling chamber by the second support pipe and then flows back to the power pump of the housing chamber by the first support pipe; Liquid impeller; the LED floodlight is not only simple in structure, easy to use, but also can effectively achieve heat dissipation.

The invention discloses an automatic cooling and cutting device for special steel production, comprising a base body, a casing device, a gear rod, a rotating sleeve and a water tank. The lower end of the base body is provided with a support frame, and the lower end of the support frame is provided with a base, and the base An adjustable support seat is arranged at the bottom of the casing, the casing device is arranged on the upper end of the base body, and a telescopic rod is arranged inside the casing device, and a compression spring is arranged on the outer side of the telescopic rod. The automatic cooling and cutting device for special steel production is provided with a fourth motor, a belt pulley, a belt, a rotating sleeve, a groove, a through slot and an electric telescopic rod, so the device can fully cool the special steel. Its working principle is : The electric telescopic rod at the lower end of the sliding seat is unfolded downward, the rotating sleeve is immersed in the coolant in the water tank, and the coolant enters the rotating sleeve along the groove on the inner side of the rotating sleeve and contacts the special steel to cool it down. At the same time, the fourth motor drives The rotating sleeve rotates to make the coolant more fully contact with the special steel.

The invention discloses a device for assisting the cooling of extracorporeal circulation of an electrolytic bath and relates to a cooling device, aiming at solving the problems that an electric pump is seriously corroded by the electrolytic solution in the existing electrolytic bath during the extracorporeal cooling and is frequently changed to consume massive financial resources. A cooling tube body is wound outside a cooling main shell, and the cooling tube body and the cooling main shell are arranged in a clearance manner, an electrolytic solution inlet end is arranged on one side surface of the cooling main shell, a first pipeline is communicated with the electrolytic solution inlet end, an electrolytic solution outlet end is arranged on the other side surface of the cooling main shell, a second pipeline is communicated with the electrolytic solution outlet end, a vertical distance from the electrolytic solution outlet end to the bottom of the cooling main shell is less than a vertical distance H from the electrolytic solution inlet end to the bottom of the cooling main shell, ladder-shaped diversion plates are obliquely arranged in the cooling main shell, two ends of the ladder-shaped diversion plates are connected with an electrolytic solution inlet and an electrolytic solution outlet, and an outer cover covers outside the cooling main shell and the cooling tube body. The device is low in manufacturing cost and electricity-saving. The device is used for cooling the electrolytic bath.

The invention relates to the technical field of self-contained power supply heat dissipation, and discloses a novel box-type substation heat dissipation device with self-contained power supply, including a cabinet, rubber bases are fixedly connected to the four corners of the bottom of the cabinet, and solar photovoltaic panels are fixedly connected to the top of the cabinet ; The rear side of the inner cavity of the cabinet is vertically upwardly fixedly connected with a heat-dissipating aluminum box. In the present invention, the two connecting pipes on the rear side of the heat-dissipating aluminum box are sealed and inserted into the butt joint holes of the heat-dissipating aluminum box, and the suction pump works in the later stage to suck the oil in the oil tank into the heat-dissipating aluminum box and discharge it. Through the docking hole into the back-type heat dissipation aluminum box, the heat of the transformer is fully cooled and dissipated in an all-round way, and the heat dissipation efficiency is higher; when there is a lot of heat in the heat dissipation aluminum box, it is exhausted through the one-way valve and the air release valve to avoid internal heat dissipation. The heat cannot be dissipated; at the same time, the four sets of exhaust fans work to fully exhaust the heat on the cooling fins to ensure the cooling effect.

A deep refrigeration regulating valve with the piston pressure self-sealing and positioning functions comprises a valve body, a lower valve cover, a lengthened valve cover, a valve rod, an executing mechanism and the like. A sleeve is arranged inside the valve body, a valve piston is arranged inside the sleeve, the upper portion of the valve piston is connected with the lower portion of the valve rod, the lengthened valve cover is arranged at the upper portion of the valve body, a piston pressure self-sealing and positioning assembly is arranged at the lower portion of the lengthened valve cover, and an upper thread of the piston pressure self-sealing and positioning assembly is connected with an internal thread at the lower end of the lengthened valve cover. An isolation drip tray and an upper valve cover are arranged on the lengthened valve cover. The upper valve cover is internally provided with sealing packing and is pressed through a packing bushing and a packing gland. The executing mechanism is arranged at the upper portion of the upper valve cover. The valve rod penetrates through the upper valve cover, the lengthened valve cover and the piston pressure self-sealing and positioning assembly. The lower portion of the valve rod is connected with the valve piston, and the upper portion of the valve rod is connected with the executing mechanism. The piston packing plays a role in soft positioning and prevents cracks, fractures and hard-positioning pull injuries, all of which are caused by bending of the lengthened valve rod, and it is guaranteed that the valve opening, closing and adjusting actions are reliable, the valve is sealed reliably and the system is safe and reliable.
