Problems solved by technology
[0003] The above-mentioned vibrating screen has the following outstanding problems: 1. The tensioning device is a multi-unit tensioning method that uses multiple gussets to tension a screen, so that the screen is subjected to too many stress points, the force is uneven, and the screen is damaged quickly. , frequent replacement
2. The sealing plates on both sides of the vibrating screen are an integral structure. When replacing the screen, the tension bolt must be removed from the inspection hole. The space is narrow and it is not easy to disassemble.
3. Since the material guide plate in front of the discharge port is fixed, the screen cannot be taken out or put in from the discharge port. When replacing the screen, the upper sealing plate must be fully opened to take out the old screen and install a new one. sieve
Inconvenient operation, long time-consuming and low work efficiency

The invention discloses a vibrating screen which comprises a seal plate, a guide plate, a screen and a screen tensioning device, wherein the screen tensioning device is formed by two tensioning units, each tensioning unit is formed by a screen side plate, a pinch plate, a screw, a nut, a screen, support angle steel, and a transverse beam, each pinch plate and each screen side plate have the same length, each pinch plate is connected with each screen side plate in a fastened mode through each screw and each nut, each pinch plate enables each screen to be tightly tensioned on the support angle steel and each transverse beam, each screen side plate is provided with a maintenance hole, four corners of each maintenance hole are circular corners, the outer side of each maintenance hole is provided with a press cover, the split-type seal plate is arranged on the outer sides of the screen side plates, and the split-type seal plate is longitudinally arranged. According to the vibrating screen, stress of the screen tends to be uniform, service life is prolonged, and replacement of the screen is convenient at the same time.
Description
technical field [0001] The invention belongs to the technical field of vibrating screens for forced intermittent asphalt mixing plants, and in particular relates to a vibrating screen which can conveniently replace the screen mesh. Background technique [0002] During the production process, the vibrating screen of the forced batch asphalt mixing plant is continuously heated and impacted by materials, which will cause the screen to be damaged. Replacing the screen is a regular task to ensure the normal operation of the vibrating screen. The vibrating screen in the prior art is tensioned from both sides of the sieve core, and the tensioning device is a multi-unit tensioning method that uses multiple buckle plates to tension one screen; the material guide plate in front of the discharge port is a fixed There are sealing plates on the upper part and both sides of the vibrating screen, and the sealing plates on both sides of the vibrating screen are integral structures, and ther...
