Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and more specifically, to an anti-bending protection device for the beam of a plate and frame filter press. Background Art

[0002] Plate and frame filtration is a common device in sewage treatment. The left and right beams are important main devices of the plate and frame filter press, which directly affect the working efficiency and quality of the plate and frame filter press. The working principle of the plate and frame filter press is that the piston of the oil cylinder moves telescopically, and the beam bears pressure to control the outer frame size of the filter press, so that the filter plates are squeezed and sealed, allowing sewage to pass through the filter cloth, leaving mud and impurities between the aluminum plates, and the clear water flows out. Since the filter plates are extremely prone to skew during the operation of the plate and frame filter press and squeeze the left and right beams during the pressing process of the filter press, causing the beams to bend and deform, and the filter plates to fall off, resulting in a major failure of the filter press to work, an anti-bending protection device for the beam of the plate and frame filter press is needed to solve this problem.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following will further describe the invention in combination with the drawings and specific embodiments: Embodiment

[0014] Reference Figure 1 Referring to Embodiment 1, it includes a machine base 1, the machine base 1 is located at the bottom of the entire device, a support frame 2 is fixedly installed on the upper end of the machine base 1, and two support frames 2 are symmetrically arranged and connected into one body through a main body 3. A head plate 5, a middle end 13 and a tail plate 6 are sequentially installed in the main body 3 from left to right, and the head plate 5, the middle end 13 and the tail plate 6 are in the same horizontal direction. A filter plate 7 is installed between the head plate 5 and the middle end 13, and left and right beams 10 are installed on the main body 3. An oil cylinder 14 is installed on one side of the left and right beams 10, and a feeding end 4 is provided on one side of the main body 3, and the feeding end 4 is located on the side close to the head plate 5. Embodiment

[0015] Reference Figure 1Description of Embodiment 2. This embodiment further elaborates on Embodiment 1 and includes left and right girders 10. A channel steel 9 is installed on the left and right girders 10. A fixed support member 8 is provided on the outer layer of the left and right girders 10. The channel steel 9 is No. 10. The left and right girders 10 are made of alloy material. A switch bracket 11 is installed at the steel channel of the left and right girders 10, and a proximity switch 12 is installed on the switch bracket 11. In this embodiment, the provided channel steel 9 is No. 10 steel, and its chemical composition and mechanical properties comply with the provisions of GB / T 710-91. This kind of steel has good plasticity and toughness. The setting of the proximity switch 12 will trigger the detection point of the proximity switch 12 to work and prevent the filter press from continuing to work when the girder shows an excessive bending phenomenon during the operation of the filter press.

[0016] In specific applications, during the operation of traditional devices, due to problems such as the failure of the pulling plate device, the looseness of the chain, and the mud clamping of the filter cloth, if the on-site personnel do not discover and handle them in time, it may cause the bending of the girder of the plate and frame filter press. In the case of a large bending, it will cause the equipment to be damaged and irreparable. In this device, No. 10 channel steel 9 is used to make the proximity switch 12 bracket 11 on the outer sides of the left and right girders 10 of the plate and frame filter press. The switch bracket 11 is fixedly connected to the fixed oil cylinder 14 side of the feed side seat frame of the filter press and can freely expand and contract, and is kept 20 mm away from the outer side of the girder to facilitate the installation of the proximity switch 12. The size of the bracket can be determined according to the size of the girders of each plate and frame filter press. According to on-site statistics, most of the bending points of the girder are located 3 - 4 meters from the center of the girder. Therefore, four proximity switch 12 control points are installed about 2 meters to the left and right of the center of the left and right girders 10, so that when the girder shows an excessive bending phenomenon during the operation of the filter press, the detection point of the proximity switch 12 will be triggered to work and prevent the filter press from continuing to work, avoiding major deformation of the girder and causing equipment damage.
