Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a uniformly distributed high-density Lamella sedimentation tank device. Background Technology

[0002] The Lamella sedimentation tank is a high-efficiency solid-liquid separation device based on the principle of inclined plate sedimentation. It is mainly used for the rapid removal of suspended solids in sewage treatment, industrial wastewater treatment or water purification processes. Its core feature is that the densely arranged inclined plate structure greatly improves sedimentation efficiency and reduces the floor space required.

[0003] The uniformly distributed high-density Lamella sedimentation tank equipment is a highly efficient water treatment sedimentation technology device. It combines the "Lamera sedimentation" principle with a high-density uniform water distribution design. It is mainly used to improve solid-liquid separation efficiency and is widely applicable to sewage treatment, industrial wastewater treatment, water purification and other fields.

[0004] In the existing uniformly distributed high-density Lamella sedimentation tank equipment, due to the single-sided water inlet distribution method of rectangular sedimentation tanks and high-density sedimentation tanks, the effective sedimentation section is actually the first half, while the treatment efficiency of the second half is low. Therefore, the transmission sedimentation tank is made very large and tall. Moreover, it has been shown that the sedimentation efficiency is also closely related to the contact area. The traditional concept of a one-meter-high inclined plate or inclined tube has a small contact area. Changing the contact area will improve the sedimentation efficiency. The radial flow sedimentation tank is relatively better than the former two types of sedimentation tanks in terms of overall water distribution, but it is a circular sedimentation tank with a very low surface load design, which occupies a lot of space. It is difficult to install inclined plates or inclined tube packing inside, so the practice of installing inclined plates is basically not adopted. The cost of installing inclined plates and inclined tubes is very high. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a uniformly distributed high-density Lamella sedimentation tank device, which has the following beneficial effects:

[0016] 1. By setting up a uniformly distributed water distribution channel system and an extended high-stability skid-mounted customized inclined plate module, the water flow pattern is uniformly distributed, the effective sedimentation area is increased several times compared to the traditional method, and the contact area of ​​the sedimentation inclined plate is increased, thus increasing the efficiency. This avoids the situation where the effective sedimentation section of the sedimentation tank is only in the first half while the treatment efficiency of the second half is low, further improving the sedimentation efficiency.

[0017] 2. By incorporating a centrally driven, dead-angle-free sludge scraping module and a high-efficiency backwashing system, the sedimentation effluent and water collection process causes near-zero disturbance to the sedimented sludge or sludge that is difficult to settle. This allows the equipment to significantly improve efficiency in the physicochemical sedimentation process of wastewater treatment, while greatly reducing the footprint. This avoids the situation where the surface load design is very low, the footprint is quite large, and it is difficult to install inclined plates or inclined tube packings inside, further reducing installation costs.

[0026] The sedimentation tank body is equipped with a uniformly distributed water distribution channel system 2. The system is fixed by the waist hole at the top of the uniformly distributed water distribution channel system 2 and the long water distribution channel module 3. Raw water enters the uniformly distributed water distribution channel system 2 through the inlet pipe 1 and is evenly distributed through the water distribution holes of the uniformly distributed water distribution channel system 2. A connecting flange is provided at the end of the uniformly distributed water distribution channel system 2, which can be disassembled and reassembled when the water volume is large, allowing for flexible use. The sedimentation tank body is also equipped with an extended high-stability skid-mounted custom inclined plate module 4.

[0027] U-shaped slots are cut into the PP inclined plates, and customized PP fixing plates and rubber blocks are used to reinforce the inclined plates, making them more stable and reliable. Positioning blocks are welded to the bottom reinforcing ribs to ensure accurate spacing and positioning of each inclined plate.

The adjustable evenly distributed water collection tank module 6 is equipped with a connecting flange with waist holes, which allows for vertical adjustment of the water outlet tank 9 during assembly. A waist hole bracket is provided at the bottom, which can be adjusted according to the actual use on site, adapting to various situations and making it more stable and reliable.

[0028] Example 2

[0029] Reference Figure 1-2This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: two centrally driven, dead-angle-free sludge scraping modules 5 are symmetrically installed at the center of the inner side of the sedimentation tank body; a high-efficiency backwashing system 11 is installed above the sludge collection trough 7 on the inner side of the sedimentation tank body; inner and outer flanges are welded and installed between the inner wall of the sedimentation tank body and the high-efficiency backwashing system and other devices 11; backwashing branch pipes are provided on the inner side of the high-efficiency backwashing system and other devices 11; several backwashing ports are opened along the height direction of the backwashing branch pipes; during backwashing, each inclined plate is ensured to make full contact, achieving advantages such as no residue; a water outlet 9 is installed at the rear end of the sedimentation tank body near the adjustable uniformly distributed water collection trough module 6; a water outlet 10 is installed at the center of the lower end of the water outlet 9; the water outlet 9 is connected to the pipe for external discharge through the water outlet 10; and the sludge collection trough 7 is connected to the pipe for external discharge through the sludge discharge port 8.

[0030] The remaining structure is the same as that in Example 1.

[0031] The workflow of this utility model is as follows:

[0032] First, the flocculated water enters the uniformly distributed water distribution channel system 2 through the main inlet pipe 1. The water is then evenly distributed into the long water distribution channel module 3 through the uniformly distributed water distribution channel system 2. The water is then stably distributed into the lower end of the sedimentation tank body through the long water distribution channel module 3. Heavier particles in the water directly sink into the mud collection trough 7. During the upward movement of the water, the flocs in the water are settled into the mud collection trough 7 through the extended high-stability skid-mounted custom inclined plate module 4, which has no internal or external corners. The clear water at the top is collected through the adjustable uniformly distributed water collection trough module 6. The flocs settled in the mud collection trough 7 are scraped into the sludge discharge port 8 through the centrally driven, dead-angle-free sludge scraping module 5.

[0033] Secondly, after the flocs settle, the clean water is evenly collected and introduced into the outlet tank 9 through the adjustable uniform water collection tank module 6. The clean water is discharged through the outlet 10 in the middle of the outlet tank 9. The flocs accumulated on the inclined plate are flushed down into the mud hopper collection tank 7 through the high-efficiency backwashing system 11.

[0034] Finally, compared to traditional equipment, it operates more stably, provides more reliable water output, is easier to operate, is highly integrated, occupies little space yet can achieve a large water processing capacity, can be transported as a whole, and is suitable for use under various harsh conditions.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
