Description

Technical Field

[0001] This utility model relates to the technical field of sludge filter press equipment, specifically to a belt filter press discharge plate. Background Technology

[0002] A large amount of residual sludge is generated during the biological treatment of wastewater. In order to protect the environment and make comprehensive use of resources, the residual sludge needs to be treated. Since the residual sludge has a high water content, it needs to be initially reduced in volume through processes such as filter pressing, which will facilitate subsequent treatment or transportation.

[0003] In the process of sludge reduction by filtration, the commonly used filter presses, including belt filter presses, are used. After the sludge is filtered by the belt filter press, it is discharged from the sludge outlet through the sludge discharge plate. Since the sludge still contains a high moisture content after filtration, it is easy to stick to the sludge discharge plate during the discharge process, which affects the stability of the sludge discharge. The traditional method can only be cleaned manually by on-site operators, which is time-consuming and labor-intensive, and is also prone to untimely handling, affecting the continuous and stable production.

[0004] Therefore, this utility model proposes a belt filter press discharge plate with raised ribs and a smooth Teflon coating, which effectively reduces the friction between the sludge and the discharge plate and avoids the vacuum conditions formed by the close contact between the sludge and the discharge plate, thus playing a positive role in ensuring continuous and stable sludge discharge.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] Embodiments of this utility model:

[0027] like Figure 1 As shown, the mud discharge plate of this utility model includes a mud guide plate 1 and a first side plate 21 and a second side plate 22 on both sides of the mud guide plate 1; an installation hole 11 is provided above the mud guide plate 1, and the mud discharge plate is fixedly connected to the mud outlet of the belt filter press through the installation hole 11 and screws; two protruding ribs 3 are provided at intervals on the mud guide plate 1, and a Teflon coating 4 is sprayed on the mud guide plate 1.

[0028] like Figure 1-2As shown, in this embodiment, the ridge 3 is a soft rope, including fine hemp rope, with a diameter of 3~5mm. A first connecting hole 211 and a second connecting hole 212 are provided on the first side plate 21, and a third connecting hole 221 and a fourth connecting hole 222 are provided on the second side plate 22. One end of the fine hemp rope passes through the first connecting hole 211 and the third connecting hole 221, and then returns through the fourth connecting hole 222 and the second connecting hole 212, forming two ridges 3 on the mud guide plate 1. The two ends of the fine hemp rope are connected and tightened by the rope tensioner 5.

[0029] The rope tensioner 5 includes a connecting frame 51, with a first connecting part 52 and a second connecting part 53 connected to both ends of the connecting frame 51. The first connecting part 52 is threadedly connected to a first threaded rod 54, and the second connecting part 53 is threadedly connected to a second threaded rod 55. The first threaded rod 54 is connected to a first hook 541 outside the connecting frame 51, and the second threaded rod 55 is connected to a second hook 551 outside the connecting frame 51. The first hook 541 and the second hook 551 are respectively engaged with one end of the thin hemp rope. In this embodiment, the threads on the first threaded rod 54 and the second threaded rod 55 have opposite directions of rotation. When the connecting frame 51 is rotated, it can be used to tighten and loosen the thin hemp rope. After the thin hemp rope is tightened, a layer of Teflon coating 4 is sprayed onto the mud guide plate 1.

[0030] like Figure 1 As shown in Figure 4-7, in this embodiment, the rib 3 is a steel wire rope or iron wire with a diameter of 3~5mm. Taking iron wire as an example, a first connecting hole 211 and a second connecting hole 212 are provided on the first side plate 21, and a third connecting hole 221 and a fourth connecting hole 222 are provided on the second side plate 22. One end of the iron wire passes through the first connecting hole 211 and the third connecting hole 221, and then returns through the fourth connecting hole 222 and the second connecting hole 212, forming two ribs 3 on the mud guide plate 1. The two ends of the iron wire are fixed and tightened by the U-shaped buckle 6 and the rope locking device 7.

[0031] One end of the wire is fixed by a U-shaped latch 6. The U-shaped latch 6 includes a lock body 61, in which a U-shaped groove 611 is provided. On both sides of the U-shaped groove 611, there are mating grooves 612 (the bottom of the mating groove 612 is a through hole). A U-shaped clip 62 is set through the mating groove 612 and engages with the U-shaped groove 611. The two legs of the U-shaped clip 62 are threaded and connected to a fastening nut 63. By tightening the fastening nut 63, the gap between the U-shaped clip 62 and the U-shaped groove 611 becomes smaller, thereby fixing the wire. When fixing the wire, the end of the wire wraps back to form an elliptical loop, which makes it more secure.

[0032] The other end of the wire is fixed and tightened by a rope locking device 7. The rope locking device 7 includes a mounting frame 71. Fixed connecting parts 711 are provided on both sides of the mounting frame 71. The fixed connecting parts 711 are fixedly connected to the outer side of the first side plate 21. A rotating shaft 74 is provided through the two side walls of the mounting frame 71. A first ratchet 72 and a second ratchet 73 are fixedly connected to the rotating shaft 74. A mating hole 741 is provided in the middle of the rotating shaft 74. The mating hole 741 mates with the end of the wire. One end of the rotating shaft 74 is supported on the mounting frame 71. The other end of the rotating shaft 74 extends to the outside of the mounting frame 71 and is provided with a rotating part 742. The rotating part 742 mates with a wrench, etc. Limiting rods 75 are also hinged to the two side walls of the mounting frame 71. The limiting rods 75 mate with the ratchet teeth of the ratchet.

[0033] After the wire is tightened, a layer of Teflon coating 4 is sprayed onto the guide plate. The same applies to the steel wire rope, so it will not be described in detail again.

[0034] The principle of this utility model is as follows:

[0035] This invention effectively prevents sludge from sticking to the discharge plate of a belt filter press, ensuring the stability of the discharge. During the process, the Teflon coating 4 is sprayed to effectively reduce the friction between the sludge and the discharge plate, preventing sludge adhesion and facilitating the smooth fall of the sludge. In addition, two protruding ribs 3 are provided on the guide plate 1, which allows a gap to be formed between the sludge and the guide plate 1 during the fall. This allows air to enter between the sludge and the guide plate 1, preventing the sludge from being tightly sucked together and unable to fall stably under atmospheric pressure, thus ensuring the stability of the discharge.

[0036] In the process of using this utility model, there are multiple ways to form the raised ridge 3. Only two are given in the embodiments of this utility model. In principle, any technical solution that can form the raised ridge 3 and cooperate with a smooth coating material to achieve the effect of this utility model should be within the protection scope of this utility model.

[0037] This utility model involves a rope tensioner 5, a U-shaped lock 6, etc., which are existing and mature components. The ratchet and the limiting rod 75 are also based on existing and mature principles. Figure 7 The arrow indicates the direction of ratchet rotation. When the ratchet rotates in the opposite direction, it is limited by the limiting rod and cannot rotate in the opposite direction. It should be noted that in this utility model, the limiting rod 75 is manually operated. When tightening is required, the limiting rod 75 is moved to separate from the ratchet. After tightening, the limiting rod 75 is engaged with the ratchet. This is easy to understand for those skilled in the art, so it will not be described in detail.
