Background
The filter press is a common solid-liquid separation device, is applied to chemical production at the beginning of the 18 th century, and is still widely applied to industries such as chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramics, environmental protection and the like. The belt filter press is a high-efficiency dewatering device which dewaters the concentrated sludge after the concentration tank so as to form a sludge cake. It features automatic control, continuous production, stepless speed regulation, and suitability for various kinds of sludge, and is suitable for dewatering sludge in water supply and drainage, papermaking, casting, leather, chemical industry, food and other industries. The sludge and the added flocculating agent are fully mixed and then enter a sludge gravity dehydration area of the belt filter press, and a large amount of water is removed by the gravity of the sludge. The gravity area is provided with a mud distributing device, which can evenly distribute the mud in the filter belt, then enter the wedge-shaped squeezing section between the upper and lower mesh belts for pre-compression dehydration, and finally enter the squeezing area to form mud cakes.
The conventional belt filter press mainly comprises an outer frame, a plurality of press rolls, supporting rollers, a filter belt and an auxiliary device group, and when the filter press breaks down or has other emergency situations, all the roll shafts need to be stopped emergently to ensure the safety of other equipment.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-3:
according to the utility model discloses a pressure filter roller arresting gear, including roller 1, arc frame 2, arrestment mechanism 3, cover frame 4 and brake cylinder 5, roller 1 bilateral symmetry is equipped with arc frame 2, and 2 inboard sides of arc frame are equipped with arrestment mechanism 3 and are connected with roller 1 through arrestment mechanism 3, and roller 1 lower extreme is equipped with pivot 6, and 2 lower extremes of arc frame are through pivot 6 swing joint, and cover frame 4 cover is arranged in 2 upper ends of arc frame, and brake cylinder 5 connects the middle part of cover frame 4 perpendicularly; this design can be pressed down by the brake cylinder 5 so that the jacket frame 4 presses the arc frame 2 to the inner side, braking from the counter roller 1.
Brake mechanism 3 includes brake shoe 31 and brake head 32, and brake head 32 outside rigid coupling is inboard in arc frame 2, and brake head 32 inboard is equipped with brake shoe 31, and brake shoe 31 can effectual increase and the frictional force of roller 1 contact to will be rapidly with the deceleration braking of roller 1.
The inner side of the brake shoe 31 is arc-shaped, so that the contact area with the roller shaft 1 can be increased, and the friction resistance is increased.
The sliding grooves 41 are formed in the two sides of the sleeve frame 4, and the arc-shaped frame 2 is sleeved in the sliding grooves 41, so that the arc-shaped frame 2 can slide back and forth in the sliding grooves 41, and the opening and closing of the arc-shaped frame 2 are controlled.
The outer side of the arc-shaped frame 2 is smoothly arranged, so that the arc-shaped frame 2 can slide conveniently.
The rubber pad 42 is arranged on the outer side of the sliding chute 41 and used for protecting the arc-shaped frame 2 and preventing the sliding chute 41 and the arc-shaped frame 2 from being extruded and damaged when being pressed.
According to the specific working principle, when the roll shaft 1 works normally, the brake cylinder 5 is in a contraction state, the sleeve frame 4 is at a high position, and the arc frame 2 is integrally arranged in an arc shape, so that the arc frame 2 can topple towards two sides under the action of gravity and is blocked by the chute 41, and at the moment, the brake shoe 31 is not in contact with the roll shaft 1, and the rotation of the roll shaft 1 cannot be influenced; when needs emergency braking, braking cylinder 5 suppresses jacket frame 4 downwards, and the middle side width increase of both sides arc frame 2, and spout 41 downstream can apply the power to the inboard to arc frame 2 for arc frame 2 folds, thereby makes brake shoe 31 and roller 1 contact completely, and brake shoe 31 increases gradually with the frictional force of roller 1 contact, thereby will be rapidly with roller 1 speed reduction braking. The device has simple structure and is convenient to set.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these are also considered to be within the protection of the present invention.
