The utility model discloses an integrated catalytic reactor used in a styrene production process. The integrated catalytic reactor comprises a gas inlet for introducing waste gas, a tubular heat exchanger, a plate heat exchanger, a catalytic bed, a temperature control device for adjusting the temperature of the waste gas in the tubular heat exchanger, and a gas outlet. Waste gas enters from the gas inlet and enters a pipe of the tubular heat exchanger from the gas inlet channel for heat exchange, so that the temperature is increased to be higher than the styrene polymerization temperature, and the waste gas enters the plate heat exchanger from the tubular heat exchanger through the first channel, is subjected to heat exchange again to increase the temperature, then enters the catalytic bed, and is subjected to catalytic reaction to form clean high-temperature flue gas; and the high-temperature flue gas passes through the third channel to the periphery of the plate heat exchanger and exchanges heat with waste gas in the plate heat exchanger, and the cycle is repeated. Waste gas in the low-temperature section is subjected to heat exchange through a tubular heat exchanger, the temperature of the waste gas is increased to be higher than the styrene polymerization temperature, and the tubular heat exchanger is not blocked; and the high-temperature section adopts the plate heat exchanger for waste heat recovery, waste heat is utilized, and the cost performance is high.

This utility model discloses a double-sided heating melting device for adhesive blocks, including a frame and a heat conduction system mounted on the frame. A melting tank is provided on the frame. The heat conduction system includes a first heating component and a second heating component. The first heating component is adapted to heat and melt the bottom of the adhesive block and convey the melted adhesive to the coating device. The second heating component is located at the outlet of the melting tank. This utility model, by placing a second heating component at the outlet of the melting tank, heats the bottom and sides of the resin respectively through the first and second heating components, enhancing the melting capacity, ensuring the resin melts and is used as soon as possible, and preventing the resin from tipping over the baffle when reaching the resin outlet, thus affecting the normal operation of the entire device.

The utility model relates to the technical field of balloon dilatation catheters, and particularly discloses a balloon dilatation catheter with a function of preventing a pipeline from falling off, which comprises a main body mechanism comprising a catheter assembly, a balloon installed on the catheter assembly and a connecting assembly; the fixing mechanism comprises a fixing assembly installed on the connecting assembly and a clamping plate assembly clamped and embedded in the fixing assembly in a sliding mode. According to the utility model, the handle is pulled until the distance between the clamping plate body and the fixing block is increased to a degree that the clamping plate body can be clamped on a workbench, and then the handle is loosened, so that the spring pushes the limiting ring to move due to deformation recovery, and the clamping plate body is further driven to recover to the original position, thereby firmly locking and fixing equipment on the workbench. The stability of the main body mechanism on the workbench is ensured, shaking in the operation process is effectively prevented, and the accuracy and safety of an operation are improved.

This utility model discloses a feeding device for the production and processing of plastic packaging bags, relating to the technical field of feeding devices. It includes: a belt conveyor for directional material conveying; a hopper installed on top of the belt conveyor, arranged in a C-shape; a material blocking device installed at the opening of the hopper, used to block material according to the discharge rate; and a discharge chute installed at one end of the belt conveyor. This feeding device, by adjusting the position of a sliding material blocking plate, allows the sliding plate to extend relative to a fixed plate, thereby extending the length of the fixed plate downwards, reducing the discharge gap, and thus facilitating the reduction of the discharge rate. This solves the problem of difficulty in adjusting the discharge rate as needed due to the fixed or inconvenient adjustment of traditional material blocking structures, and eliminates the need to stop the machine for adjustment, significantly improving production efficiency.
