The present application relates to the technical field of catalyst regeneration, in particular to a gas-solid countercurrent enhanced stripping device for catalyst regeneration, comprising: a mounting frame and an inclined plate assembly. The inclined plate assembly is arranged inside the mounting frame, used for guiding the flow of catalyst particles and capable of prolonging the contact time of catalyst particles with water vapor. Further, when the catalyst particles impact the inclined plate assembly under the action of gravity, the inclined plate assembly can absorb kinetic energy through its elastic deformation, converting rigid collision into cushioned contact. Therefore, on the one hand, the impact force of the catalyst particles on the inclined plate assembly is reduced, which not only slows down the wear of the catalyst particles themselves, but also avoids the abrasion of the inclined plate assembly; on the other hand, the slight vibration induced by elastic deformation can disturb the flow state of the catalyst particles, promoting them to spread evenly on the inclined plate assembly, thereby improving the contact efficiency between the catalyst particles and water vapor and further improving the stripping efficiency.

A second compression spring is connected between the pressing part and the edge grinding bracket. This invention can remove burrs from the sides and top surfaces of the PCB circuit board edges, removing burrs cleanly and efficiently, ensuring complete removal without omissions, and providing uniform grinding force to avoid damaging the circuit board.

The utility model relates to a split type stator structure, comprising a stator iron core which comprises two symmetrical stator iron core base bodies; a coil wound on the stator core; and each insulating frame is arranged between the corresponding coil and the corresponding stator iron core base body and covers the whole inner surface of the stator iron core base body. The stator iron core of the split type stator structure is arranged to be two symmetrical stator iron core base bodies so as to form a folding structure, the winding slot fullness rate can be improved, the output power and the torque of the motor are further improved, and independent winding can be carried out on the single stator iron core base body after the stator iron core base body is opened so as to improve the winding efficiency. And each insulating frame covers the whole inner surface of the stator iron core base body, so that electric leakage and coil abrasion can be effectively prevented.

The utility model relates to food safety design field discloses a kind of automatic rotating lollipop toys, including handle, the handle inside is provided with switch, the handle top is fixedly connected with micro motor, the micro motor top is fixedly connected with transmission rod, the transmission rod top is rotatably connected with fixed base, the fixed base inside is slidably connected with sliding rod, the sliding rod one end is fixedly connected with magnet two, the magnet two is fixedly connected in the end of fixed base away from round cap, the sliding rod bottom is fixedly connected with latch, the end of sliding rod away from magnet two is fixedly connected with round cap. In the utility model, the waterproof touch switch in handle is started, the top of which is fixed by food-grade PP buckle micro motor, the food-grade PP material transmission rod fixed on top is driven by micro motor to rotate, so as to realize candy automatic rotation, convenient replacement of sugar core, prevent hand abrasion and avoid the comprehensive effect of sugar liquid infiltration short circuit.

The utility model provides a kind of for angle stroke valve non-contact installation mechanism, at least two clamping holes are opened in the gripping handle of valve upper portion, positioning hole is opened in the flange plate of valve upper portion, and it is matched with clamping hole, installation mechanism includes the clamping rod matched with clamping hole, the number of clamping rod is equal to the number of clamping hole, the upper portion of clamping rod is provided with connecting plate, the outside of connecting plate is provided with force applying element, the utility model can be clamped into the clamping hole and positioning hole matched with it by clamping rod, then it is tightened operation by the aid of force applying element, it can be realized not to contact angle stroke valve to realize the firm efficient installation or dismounting operation to it, greatly improve the efficiency of installation and dismounting, operation is more convenient and efficient.

The utility model provides a kind of display screen and television, it is related to display device technical field.The display screen of the utility model can include screen body, diffuser plate, diaphragm and first paste layer, screen body, diaphragm and diffuser plate are sequentially arranged from front to back, first paste layer is arranged between diaphragm and diffuser plate, and it is located the position of diaphragm close to upper side, to paste the position of diaphragm close to upper side at diffuser plate, since diffuser plate is relatively thick, its hardness is greater, bending is smaller when stressed, and diaphragm is pasted at diffuser plate due to upper side, therefore diaphragm will not be stressed wrinkle bending, therefore display screen will not rub with polaroid of screen body rear side in the transportation process, to avoid abrasion screen body further.This in addition, since the diaphragm will not appear wrinkle bending, therefore in the case where not affecting visual effect can appropriately reduce the distance of screen body to diaphragm, reduce the thickness of display screen, finally can reduce the thickness of whole machine, make whole machine more beautiful.
