The invention relates to the technical field of solid waste environment-friendly treatment, and particularly discloses a solid waste treatment device. A placing frame and a conveying belt; and the collecting mechanism is arranged on one side of the placing frame, and the collecting mechanism can collect the magnetic substances. The magnetic material collecting device at least has the following beneficial effects that through arrangement of a collecting mechanism and a variable resistance mechanism, a fixed motor is started to drive a rotating roller and a conveying belt to rotate, magnetic materials fall into a collecting box along with movement of the conveying belt, and after a first contact plate gets close to a proximity switch, a micro motor is started to drive a sealing plate to move upwards through a rotating lead screw; magnetic substances in the collecting box fall into a temporary storage box, the temporary storage box under gravity moves downwards to extrude a gas plate, gas enters a pneumatic pipe through a three-way valve to push a pneumatic rod to move, the pneumatic rod moves to push a sliding block of a sliding rheostat to move to change resistance, and therefore the power of a fixed motor is changed.

This utility model discloses a quick clamping device for sensor patches, including a quick clamping mechanism, a pressure head, a clamping body, and screws. The quick clamping mechanism is adjustablely installed at one end of the clamping body, and the pressure head is located at the other end of the clamping body. It is used to press the sensor placed in the clamping body against the end of the quick clamping mechanism. The screw is threaded onto the clamping body to lock the quick clamping mechanism. By setting a push-pull quick clamp, the sensor patch can be quickly clamped. Compared with the traditional clamping method, the work efficiency is greatly improved, meeting the needs of quick positioning and fixing of sensor patches in the production process. By setting a spring and a pressure plunger, when the quick clamping mechanism is pushed, the sleeve position is fixed and the stroke of the quick clamp is fixed. Therefore, after the quick clamp is pulled down, the compression distance of the spring is fixed, so the clamping force provided is constant, thereby providing a stable force in the pressure curing process.
