Therefore Chinese Patent Publication No. CN203342511U discloses a vacuum box rollover lifting device, which allows the vacuum box to be turned over, so that the vacuum box can be turned over during cleaning and maintenance. The left end of the channel steel is supported by bolts. When turning over, the bolts need to be removed, which is very troublesome and the degree of automation is not high. Moreover, when the cylinder is pushed and pulled too fast during the turnover, it is easy to generate momentum on the vacuum box. easily damaged

The invention discloses an improved vacuum chamber side-turn lifting device, which comprises a machine frame and a vacuum chamber. The bottom of the vacuum chamber is fixed to two rotary steel channels, the vacuum chamber is arranged in the middle of the machine frame, a lock motor is fixed to a left support of the machine frame, a drive screw is connected to an output shaft of the lock motor through a coupler, the drive screw is in screw joint to two support plates, the two support plates are fixed to the left support, a movable block is in screw joint to the drive screw, an L-shaped support block is fixed to the movable block, the left ends of the rotary steel channels abut against the L-shaped support block, the right portions of the rotary steel channels are hinged to a right support of the machine frame through a pin shaft, a push air cylinder is hinged to a horizontal beam under the right support, and the end of a push rod of the push air cylinder is hinged to the right ends of the rotary steel channels. The improved vacuum chamber side-turn lifting device can enable the left end of the vacuum chamber to automatically move away from the L-shaped support block, can achieve side turn through the push air cylinder and can guarantee turn stability of the rotary steel channels through a buffer spring and a plastic elastic plate.
Description
Technical field: [0001] The invention relates to the technical field of supporting equipment for vacuum filters, and more specifically relates to an improved vacuum box rollover lifting device. Background technique: [0002] The filter in the prior art is mainly a belt-type vacuum filter. The vacuum box is arranged at the bottom of the filter belt. The vacuum box collects the filtrate flowing out of the filter holes on the filter belt, and transports it out through the connection of the pipeline and the vacuum drain tank. The vacuum drain tank is connected to the vacuum pump, and the filtrate needs to flow into the vacuum drain tank by gravity. Since the flatness of the working surface of the vacuum box must ensure the sealing requirements, airtightness must be ensured after the overall assembly, and no vacuum is allowed; and the vacuum box During long-term use, the filtrate will remain in the box, and the residue in the filtrate will crystallize and scale, which increases t...
