The invention relates to a return pulley (101..110) for a continuous casting system, said return pulley comprising a drum-shaped main body and at least one heating pipe (2, 5, 6) laid underneath a cylindrical surface of the pulley (101..110). The heating pipe(s) (2, 5, 6) each has / have at least one input and at least one output offset in relation to said input, the sum of the inputs and outputs being at least three. The invention further relates to a continuous casting system having a return pulley (101..110) of the above type.

The invention discloses a thermocompression bonding wheel for a drip irrigation belt. The thermocompression bonding wheel of the drip irrigation belt comprises an oil supply and distributing joint, a central shaft, an oil feeding pipe, a wheel strake, an oil channel baffle plate, a right side wheel flange, a left side wheel flange, a heat sealing pressing wheel, an external stainless steel protecting plate, a first joint, a second joint and a hose; the oil supply and distributing joint is fixedly connected to one end of the central shaft, and the other end of the central shaft is connected with a motor; the oil feeding pipe is positioned into an internal chamber of the central shaft; one end of the oil feeding pipe is connected with the oil supply and distributing joint while the other end of the oil feeding pipe is connected with a temperature control device; the wheel strake is arranged outside the central shaft in a sleeving way and is fixedly connected with the central shaft; a left annular groove and a right annular groove are respectively arranged on the edges of both sides of the wheel strake; the left side wheel flange and the right side wheel flange are respectively arranged in the left annular groove and the right annular groove, and moreover, the heat sealing pressing wheel is mounted in a clearance formed between the left side wheel flange and the right side wheel flange; and the heat sealing pressing wheel is arranged outside the wheel strake in the sleeving way. The thermocompression bonding wheel of the drip irrigation belt disclosed by the invention integrates the heating function and the extruding function, therefore, good effect of heating is achieved; and a copper-made heat sealing pressing wheel is adopted, by which the surface layer of a film can be prevented from being adhered to other layers.

A food table device (100), for example, a salad table, the food table device (100) includes: a cooling system with a refrigeration device (550); a cabinet device (300) with a plate holding device (103), the table A plate (104) is arranged in said plate holder (103). The cooling system is adapted to cool the food table arrangement (100) so as to provide at least two different climate zones (Z1, Z2), the cooling of the at least two different climate zones (Z1, Z2) being individually controllable and the cooling system includes an evaporator (555), cooling device (200) arranged close to and above the back wall of the dinner plate and adjacent to the The pan covers the rear section of the device (110), so that the cooling air will flow out from the lower edge of the cooling device due to self-convection, out over the food product and upwards towards the upper edge of the cooling device, forming a first climate zone. Plate holder elements (106A, 106B) are arranged in said holding means (103) such that in said holding means, between said plate holder elements and said plate's bottom wall and transverse wall The second climate zone (Z2) is formed in between.

The invention discloses a steam mixer. The top of one end of the heater shell is connected to the main steam pipe through a flow regulating valve, the other end of the heater shell is connected to the mixed steam pipe through a gate valve or a cut-off valve, and the main steam pipe is passed through a gate valve or a cut-off valve. The valve is connected to the mixed steam pipe, and the bottom of the heater housing opposite to the inlet of the main steam pipe is connected to the heating steam pipe through a flow regulating valve. The steam distribution pipes are evenly distributed along the axial direction of the heater shell, and the heating steam pipes are extended into the heater shell with combined nozzles. Mix a large flow of saturated steam and a superheated steam in the equipment to form a slightly superheated steam with a certain degree of superheat; it has high heat exchange efficiency and can effectively reduce the generation of steam when the pipe network transports The impact of water hammer is powerful for the safe operation of the pipe network.
