Description

Technical Field

[0001] The utility model relates to the technical field of contact oxidation tanks, in particular to a filler rack for a contact oxidation tank used for wastewater treatment. Background Art

[0002] As an efficient biological treatment device, the contact oxidation tank is widely used in wastewater treatment and water quality purification. It mainly uses microorganisms (such as bacteria) to contact the organic substances in the wastewater, and through biochemical reactions, converts the organic substances into harmless carbon dioxide and water. The filler in this device, as the carrier of the biofilm, plays a crucial role. In the prior art, the filler is fixed on the integrally arranged filler rack. Once the filler is damaged, the replacement process becomes complex and time-consuming because the wastewater in the oxidation tank needs to be completely drained before replacement, which often takes a long time and seriously affects the continuity and efficiency of wastewater treatment. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is how to achieve the rapid replacement of damaged filler without affecting the efficiency of wastewater treatment.

[0004] The technical solution adopted by the utility model is: a filler rack for a contact oxidation tank used for wastewater treatment, including an oxidation tank, in which there are several vertically arranged filler racks arranged in sequence. The filler rack includes a first cross plate and a second cross plate which are parallel and arranged in upper and lower layers, and a first guide rail arranged on the side wall of the oxidation tank. The first cross plate is installed at the top of the first guide rail, and a limiting plate is arranged on the top surface of the first cross plate for limiting. The second cross plate is slidably connected with the first guide rail and is located at the bottom of the first guide rail.

[0005] After adopting the above structure, the following beneficial effects are achieved:

[0006] (1) By designing the filler rack to include a first cross plate and a second cross plate which are parallel and arranged in upper and lower layers, and a first guide rail arranged on the side wall of the oxidation tank, the modularization of the filler rack is realized, which is convenient for the rapid replacement and maintenance of the filler. It enables the operator to replace the damaged filler separately without emptying the entire oxidation tank, improving the working efficiency of filler replacement.

[0007] (2) The first cross plate is limited at the top of the first guide rail by the limiting plate, ensuring the fixed position of the filler rack in the oxidation tank, preventing the first cross plate from continuing to slide along the first guide rail to the bottom position of the oxidation tank, and also preventing the first cross plate from shaking under the impact of water flow. At the same time, the second cross plate is slidably connected with the first guide rail, which helps the second cross plate to move smoothly during filler replacement, reducing the operation difficulty.

[0008] (3) The vertical arrangement of the packing rack improves the space utilization rate inside the oxidation tank, realizes a higher packing density within a limited space, and improves the efficiency of wastewater treatment.

[0009] Preferably, the top surface of the first cross plate is provided with a plurality of continuously arranged and spaced grooves, and mounting plates are installed in the grooves.

[0010] The continuously arranged grooves provide installation positions for the mounting plates, ensuring that the mounting plates do not displace on the first cross plate and maintaining a certain distance between the mounting plates to reserve space for the installation of the packing.

[0011] Preferably, through holes for tying the packing are provided at both ends of the mounting plate, and mounting members are provided on the top surface of the second cross plate corresponding to the positions of the mounting plates, and the mounting members are symmetrically arranged at both ends of the second cross plate.

[0012] By providing through holes for tying the packing at both ends of the mounting plate, the tying between the packing and the mounting plate is made more firm, preventing the packing from displacing or falling off under the impact of water flow. And by providing mounting members on the second cross plate and corresponding to the positions of the through holes on the mounting plate, it ensures the balanced force of the packing tied between the mounting plate and the mounting members in the vertical direction.

[0013] Preferably, first lifting rings are provided at both ends of the first cross plate.

[0014] The setting of the first lifting rings enables the operator to more easily lift the entire packing rack with a lifting device.

[0015] Preferably, a threaded rod is rotatably connected between the first cross plate and the second cross plate, and a handwheel is provided at one end of the threaded rod away from the second cross plate.

[0016] The setting of the threaded rod and the handwheel enables the operator to manually adjust the relative position of the second cross plate with respect to the first cross plate. This means that even if there is wastewater in the oxidation tank, the position of the damaged packing can be adjusted by rotating the handwheel. Compared with the traditional method that requires all the wastewater in the oxidation tank to be drained before the packing can be treated, this design greatly improves the replacement efficiency of the damaged packing.

[0017] Preferably, a second guide rail is provided between the first cross plate and the second cross plate, a guide block is slidably connected to the second guide rail, and a fixing plate for tying the packing is provided on one side of the guide block facing the second guide rail.

[0018] By arranging a second guide rail between the first cross plate and the second cross plate, setting a guide block slidably connected to the second guide rail, and further arranging a fixing plate on the guide block, the packing is tied to the through hole of the mounting plate and the fixing plate of the guide block. At this time, the guide block can be placed into the second guide rail. Under the action of its own gravity, the guide block will move along the second guide rail towards the bottom of the oxidation pond until it reaches the bottom of the oxidation pond. The operator no longer needs to tie the bottom end of the packing to the second cross plate, and the design of the second guide rail and the guide block also facilitates the replacement of damaged packing in the later stage, improving the operation efficiency.

[0019] Preferably, a baffle is provided at one end of the fixing plate away from the guide block.

[0020] Arranging a baffle at one end of the fixing plate away from the guide block can effectively prevent the lateral movement of the packing under the impact of water flow and prevent the packing from accidentally falling off from the end of the fixing plate. Especially when encountering a large hydraulic action, the blocking effect of the baffle is particularly important, which can avoid the loss of the packing and reduce the maintenance cost.

[0021] Preferably, a second lifting ring is provided on the top surface of the mounting plate.

[0022] Arranging a second lifting ring on the top surface of the mounting plate enables the operator to more precisely control the lifting of a single mounting plate. When the packing in the packing rack is damaged, there is no need to lift the entire packing rack, and only the mounting plate corresponding to the damaged packing needs to be lifted to complete the replacement of the damaged packing.

[0023] Preferably, the guide block is made of a magnetic material, and a magnetic part is provided at the bottom end of the second guide rail, and the magnetic part attracts the guide block.

[0024] The magnetic part arranged at the bottom end of the second slide rail will attract the guide block made of magnetic material, which can significantly enhance the stability of the guide block on the second guide rail, ensure that the guide block will not be displaced under the impact of water flow, and the use of magnetic connection makes the installation and disassembly of the guide block simple and fast. The operator can easily lock the guide block through the magnetic part automatically, reducing the need for complex mechanical locking devices, and reducing the maintenance cost and potential failure rate.

Detailed implementation manners

[0036] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the attached Figures 1-9 Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0037] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] Embodiment 1

[0039] The following will be further described in conjunction with specific embodiments. Refer to Figures 1-4 As shown, this embodiment is a packing rack 1 for a contact oxidation tank used for wastewater treatment, including a number of packing racks arranged in sequence. Each packing rack includes two parallel horizontal plates, a first horizontal plate 3 and a second horizontal plate 6, installed on the side wall of the oxidation tank 1 is a first guide rail 2, and the first horizontal plate 3 and the second horizontal plate 6 are respectively installed in the first guide rail 2 in the vertical direction. The setting of the first guide rail 2 ensures the stable positioning and smooth movement of the packing rack. The first horizontal plate 3 is installed on the first guide rail 2 through a limit plate 302 to prevent the first horizontal plate 3 from sliding down. At both ends of the first horizontal plate 3, that is, on the top surface of the limit plate 302, a first lifting ring 5 is welded, which is convenient for hoisting when replacing the packing of the packing rack. And on the top surface of the first horizontal plate 3, there are a number of continuously arranged grooves 301 for fixing the mounting plate 4. Through holes 401 are designed at both ends of the mounting plate 4, and the through holes 401 are used for tying the packing to ensure that the packing is tightly connected to the mounting plate 4. On the top surface of the second horizontal plate 6 at the bottom of the oxidation tank 1, there are mounting parts 7, which are symmetrically distributed at both ends of the top surface of the second horizontal plate 6 and correspond to the positions of the mounting plates 4 on the first horizontal plate 3. Their function is to fix the lower end of the packing. Cooperating with the mounting plate 4, the packing installed between the mounting plate 4 and the mounting parts 7 forms a stable hanging structure. Due to the weight of the packing itself, the mounting plate 4 is tightly stuck in the groove 301 of the first horizontal plate 3, realizing the firm fixation of the packing. And thanks to the sliding characteristics of the first horizontal plate 3 and the second horizontal plate 6, once it is found that the packing is damaged or falls off, the operator can lift the entire packing rack out of the oxidation tank 1 without discharging the wastewater in the oxidation tank 1, and can quickly replace the damaged packing, greatly improving the maintenance efficiency, and at the same time ensuring the continuity and efficiency of the wastewater treatment process.

[0040] Working principle:

[0041] The first guide rail 2 installed on the side wall of the oxidation tank 1 provides stable vertical guidance for the packing rack, ensuring that the packing rack can slide in a predetermined direction. The packing rack is composed of the upper and lower parallel first horizontal plate 3 and second horizontal plate 6. Among them, the first horizontal plate 3 is fixed at the top of the first guide rail 2, and on the top of the first horizontal plate 3, there are continuously arranged grooves 301 for fixing the mounting plate 4. Through holes 401 are provided at both ends of the mounting plate 4, and through these through holes 401, the packing is tied. At the same time, the mounting parts 7 provided on the second horizontal plate 6 correspond to the positions of the mounting plates 4 on the first horizontal plate 3, jointly fixing both ends of the packing to form a stable hanging mechanism. The packing relies on its own weight to make the mounting plate 4 tightly stuck in the groove 301 of the first horizontal plate 3, preventing the mounting plate 4 from shaking. Thanks to the sliding design of the first horizontal plate 3 and the second horizontal plate 6, when it is necessary to replace the damaged packing, the operator can lift the seasoning rack out of the oxidation tank 1, and the maintenance can be quickly completed without draining water.

[0042] Example 2

[0043] As Figure 5 shown, the difference between this embodiment and Embodiment 1 is that a threaded rod 8 is rotatably installed on the first cross plate 3 and the second cross plate 6, the first cross plate 3 is fixed to the first guide rail 2 by a locking bolt, and a hand wheel 9 is installed at a position of the threaded rod 8 away from the bottom of the oxidation tank 1. By rotating the hand wheel 9, the movement of the second cross plate 6 along the direction of the first guide rail 2 can be realized. When it is necessary to greatly replace the packing in the oxidation tank 1, at this time, without draining the wastewater in the oxidation tank 1, by rotating the hand wheel 9, the threaded rod 8 will drive the second cross plate 6 to move upward along the direction of the first guide rail 2 from the bottom of the oxidation tank 1, so as to drive the packing to move from the bottom end of the oxidation tank 1 to the top end of the oxidation tank 1, which is convenient for the staff to replace the packing.

[0044] Example 3

[0045] As Figures 6-8 shown, the difference between this embodiment and Embodiment 1 is that a second guide rail 10 is fixedly connected to the bottom surface of the first cross plate 3 by bolts, guide blocks 11 are slidably connected to both sides of the second guide rail 10, a fixing plate 1101 for fixing the packing is arranged on the outer surface of the guide block 11, and a second lifting ring 13 is arranged on the top surface of the mounting plate 4, so that the operator can more accurately control the lifting of a single mounting plate. When the packing is damaged, there is no need to lift the entire packing rack, and only the mounting plate corresponding to the damaged packing needs to be lifted to complete the replacement of the damaged packing; in use, the top end of the packing is fixed in the through hole 401 arranged on the mounting plate 4, the bottom end of the packing is bound on the fixing plate 1101, and a baffle 1102 is arranged at one end of the fixing plate 1101 away from the second guide rail. After the packing is fixed, the guide block 11 is placed into the second guide rail 10, and the guide block 11 will drive the packing to slide to the bottom end of the second guide rail 10 under its own gravity until it falls on the second cross plate 6.

[0046] Example 4

[0047] As Figure 9 shown, on the basis of Embodiment 3, the material of the guide block 11 in Embodiment 3 is changed to a magnetic material, and a magnetic part 12 is arranged at the bottom end of the second guide rail 10. After the packing is bound on the mounting plate 4 and the guide block 11 and placed in the second guide rail 10, it slides to the bottom end of the second guide rail 10 under its own gravity and is attracted by the magnetic part 12 arranged at the bottom end of the second guide rail 10, so as to prevent the displacement that the guide block 11 may occur in the second guide rail 10 when the packing is impacted by water flow.
