Description

Technical Field

[0001] The present invention discloses a multi-stage limiting detachable filtering structure and a filter press, which are more convenient to clean or replace and belong to the technical field of sewage treatment, and particularly to a detachable filtering structure and a filter press, which can make the connection between the holding frame and the upper transmission pipe tighter through the snap connection between the handle and the first limiting groove, the snap connection between the mounting groove and the mounting block, and the snap connection between the bending block and the bending groove, and are more convenient for cleaning or replacing the transmission filter belt. Background Art

[0002] In sewage treatment, filter press is usually used to separate solid and liquid and dehydrate sewage to reduce the water content of sludge. Its working principle is that after the concentrated sludge is fully mixed with a certain concentration of flocculant in a static and dynamic mixer, the tiny solid particles in the sludge are aggregated into larger floccules, and free water is separated at the same time. The flocculated sludge is transported to the concentrated gravity dehydration filter belt. Under the action of gravity, the free water is separated to form stagnant sludge, which is then clamped between the upper and lower mesh belts. Under the action of extrusion pressure and shear force from small to large in the wedge-shaped pre-pressure area, low pressure area and high pressure area, the sludge is gradually squeezed to achieve the maximum separation of mud and water, and finally form a filter cake for discharge. However, the flocculant in the traditional filter press is added into the mixer through the dosing device. When the flocculant is added, it only exists in a certain position of the mixer and is added unevenly. Since the sewage continuously flows into the mixer at a certain flow rate, the sewage and the flocculant cannot fully contact each other before entering the next link, so that part of the sewage cannot be flocculated and flocculent clumps cannot be produced, resulting in low sewage treatment efficiency and poor treatment effect; and when the flocculated sludge moves with the filter belt, a lot of sludge will coagulate and remain on the filter belt, resulting in part of the sludge cannot enter the next link from the filter belt, and is squeezed into a mud cake. There is a lot of residual sludge on the filter belt, which is difficult to clean, affecting the dehydration effect of the filter belt, resulting in low sewage treatment efficiency and poor treatment effect.

[0003] Announcement No. CN107473563A discloses a belt filter press, which mainly includes a frame, a flocculation zone, a concentration and dehydration zone, a gravity dehydration zone and a pressing and dehydration zone, wherein the flocculation zone is provided with a flocculation agitator; the concentration and dehydration zone includes a plurality of horizontally arranged transmission rollers and a concentration filter belt arranged on the transmission rollers; the gravity dehydration zone is located below the concentration and dehydration zone, and the gravity dehydration zone includes a plurality of arc-shaped clamping rollers, an upper filter belt and a lower filter belt fixed on the frame and arranged obliquely; the pressing and dehydration zone includes a plurality of vertically staggered pressing rollers and pressing filter belts, and a demuding roller is also provided at the rear of the pressing roller, and a mud scraper is connected to the demuding roller. The flocculation zone of the above-mentioned filter press is equipped with a flocculation mixer, which can promote the full contact between sewage and flocculant and produce more floccules. However, when the flocculated sludge in the above-mentioned filter press moves with the upper filter belt and the lower filter belt, a lot of sludge will solidify and remain on the upper filter belt and the lower filter belt, resulting in part of the sludge being unable to enter the next link from the upper filter belt and the lower filter belt and being squeezed into mud cakes. There is a lot of residual sludge on the upper filter belt and the lower filter belt, which is difficult to clean, affecting the subsequent gravity dehydration effect, thereby resulting in low sewage treatment efficiency and poor treatment effect.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A filter press", in which the main driving pulley is driven to rotate by a third rotating motor, the main driving pulley drives the slave driving pulley to rotate, the slave driving pulley drives the third rotating rod to rotate, the third rotating rod drives the spiral blade to rotate, the spiral blade pushes the flocculated sludge from one end of the transmission pipe to the other end, and the water in the sludge enters the drainage channel from the mesh of the transmission filter belt under the action of gravity and the squeezing of the spiral blade, and is discharged from the drainage channel. When the flocculated sludge in the above filter press moves with the transmission filter belt, although the push of the spiral blade can reduce the residue of the flocculated sludge on the transmission filter belt, some sludge will still solidify and remain on the transmission filter belt. After long-term use, the transmission filter belt needs to be cleaned or replaced to ensure the dehydration effect of the transmission filter belt, but the transmission filter belt of the above filter press is not detachable, which is not convenient for cleaning or replacing the transmission filter belt, thereby affecting the dehydration effect of the transmission filter belt.

[0017] The difference between this embodiment and embodiment 1 is that: the side surfaces of the main upper pressure roller (14), the secondary upper pressure roller (36), the main lower pressure roller (15) and the secondary lower pressure roller (35) are evenly provided with a plurality of rubber teeth (38), and the rubber teeth (38) are triangular prism structures with the edges facing outwards; when in use, the rubber teeth (38) can further increase the squeezing force of the upper and lower pressure rollers on the upper and lower filter belts (34), so that the upper and lower filter belts (34) have a better dehydration effect on the sludge that has undergone the primary dehydration treatment, and the water content of the sludge is lower; The stirring blade (25) is designed with an arc-shaped structure, which can increase the contact area between the stirring blade (25) and the sewage and flocculant entering the flocculation mixing cylinder (2), and stir the sewage and flocculant, so that the sewage entering the flocculation mixing cylinder (2) can be more fully in contact with the flocculant, resulting in more sludge after flocculation; The plurality of stirring blades (25) are designed to rotate in different directions under the drive of the plurality of second rotating motors (29); the first rotating motor (3) drives the first rotating rod (23) and the stirring blade (25) to rotate in the same direction, and the second rotating motor (29) drives the second rotating rod (24) and the corresponding single stirring blade (25) to rotate in different directions, so that the sewage entering the flocculation mixing cylinder (2) can be more fully contacted with the flocculant, and more sludge can be flocculated; The height of the transmission pipe (6) is designed to gradually increase from one end to the other end. After the transmission filter belt (21) at the bottom of the transmission pipe (6) performs the first dehydration treatment on the flocculated sludge, the water in the sludge is discharged through the mesh of the transmission filter belt (21), thereby preventing the discharged water from flowing back into the sludge and affecting the dehydration effect of the sludge.

When the dehydrated sludge enters the mud collecting box (16), it is easy to be squeezed into blocks under the action of gravity. The mud collecting box (16) with one side being an openable and closable structure is more convenient for directly transferring the sludge in the mud collecting box (16) and can prevent the sludge from accumulating at the bottom of the mud collecting box (16) to form stubborn sludge.

[0018] The flocculation component can be used to make the sewage and the flocculant fully contact, so that more sludge is produced after flocculation. The sludge is pushed and dehydrated for the first time through the transmission component, and the sludge is dehydrated again through the filter press component, so as to improve the efficiency and effect of sewage treatment.
