Plate device pulling of filter press

Abstract

The invention discloses a plate pulling device of a filter press. The plate pulling device is applied to a filter press. The filter press comprises two main beams which are symmetrical left and right,and a plurality of discharging plate groups are arranged between the two main beams. Each discharging plate group comprises a plurality of filter plates which are arranged side by side and are adjacently connected, and filter plate handles capable of walking on the main beams are arranged on the two side edges of the filter plates. The plate pulling device comprises a transmission chain which isarranged on the two main beams and runs along the discharging moving direction of the filter plates, and driving mechanisms which are arranged on the two sides of at least the first filter plates or on the two sides of the filter plate handles of the first filter plates in the discharging plate groups. Each driving mechanism comprises at least one chain wheel which is meshed with the transmissionchain and idles, wherein at least one chain wheel is provided with a stop dog. The plate pulling device has the beneficial effect that the discharging efficiency of the filter plates is improved.

Description

technical field [0001] The invention relates to a plate pulling device of a filter press, which is mainly used in the technical field of filter press unloading. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. In the prior art, when unloading after the press filter is completed, the filter plate is usually pulled by a trolley, so that the gap between adjacent filter plates is opened to drop the filter cake. There are two main problems in this unloading method: first, The operating object of the plate trolley is single, and only one filter plate or a group of filter plates can be moved and unloaded per unit time. Interval unloading or synchronous unloading during part of the time period has serious shortcomings in terms of efficiency; secondly, the operating mechanism of the pull plate trolley is...

Problems solved by technology

In the prior art, when unloading after the press filter is completed, the filter plate is usually pulled by a trolley, so that the gap between adjacent filter plates is opened to drop the filter cake. There are two main problems in this unloading method: first, The operating object of the plate trolley is single, and only one filter plate or a group of filter plates can be moved and unloaded per unit of time. The interval between adjacent unloading is long, and it is impossible to realize short-cut Interval unloading or synchronous unloading during part of the time period has serious shortcomings in terms of efficiency; secondly, the operating mechanism of the pull plate trolley is prone to errors, and it uses two claws to cooperate with the filter plate and drive it to move. And the relevant structure for executing the claw action is relatively complicated and cumbersome, and it is easy to run wrong. In addition, when the steering of the pull trolley is blocked by movement, the frequency converter detects that the motor current exceeds the threshold, and gives the motor command to drive the pull trolley to turn in reverse. In application, when the puller trolley drives the filter plate to move, its stress is not stable. Under the interference of external factors or objective environment, it is easy to misjudge the steering, which not only causes low efficiency, but also easily causes damage to the motor of the puller trolley. even scrapped

Although the structure of the mating part of the pulling trolley and the filter plate has been simplified and the stability after mating has been enhanced, the problem of single operation object, low efficiency and easy misjudgment of steering has not been solved.
