Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a non-powered pulse agitator. Background Technology

[0002] In existing wastewater treatment plants, the high-concentration sludge remaining after wastewater treatment is collected in a buffer sludge storage tank, and then pumped to a sludge dewatering machine for dewatering. High-concentration sludge typically has a moisture content between 98% and 99.2%. If left to stand in the storage tank for a period of time, it will settle at the bottom. Prolonged settling will cause caking, resulting in uneven sludge concentration on the dewatering machine and potential blockage of the sludge pipes. Therefore, wastewater treatment plants generally install mixers to agitate the sludge. Due to the high sludge concentration, a high-power mixer is required, and improper configuration can lead to localized sludge accumulation in dead corners. If the mixer malfunctions, it will disrupt normal production. Utility Model Content

[0003] The purpose of this invention is to provide a non-powered pulse stirrer that requires no power drive, thereby reducing energy consumption and operating costs.

[0004] Based on the above problems, the technical solution provided by this utility model is as follows:

[0005] Non-powered pulse stirrers, including:

[0006] A water storage tank is installed above a mud storage tank to temporarily store a mud-water mixture.

[0007] A pulse generator, disposed within the water storage tank, includes a siphon pipe fixed to the water storage tank and extending to the outside of the water storage tank at its lower end, a pulse cover fixed to the outer wall of the siphon pipe and covering the siphon pipe, and a siphon breaking component fixed along the inner wall of the pulse cover. The upper end of the siphon breaking component is close to the top of the pulse cover, and the lower end extends to the lower part of the pulse cover and protrudes outside the cover wall. The lower end of the siphon breaking component is an air inlet, and the upper end is an air outlet.

[0008] A pulse diffuser, which is connected to the siphon and extends to the bottom of the sludge storage tank, includes a main drainage pipe connected to the siphon and multiple diffusion branch pipes connected to the main drainage pipe, and the diffusion branch pipes are provided with multiple water outlet holes.

[0009] In some embodiments, the siphon destruction assembly includes two siphon destruction tubes symmetrically arranged on both radial sides of the pulse shield, the diameter of the siphon destruction tubes being smaller than that of the siphon tubes.

[0010] In some embodiments, the main body of the siphon destruction tube is fixed to the inner wall of the pulse hood and its lower end is bent and extends to the outside of the pulse hood.

[0011] In some embodiments, the height of the upper end of the siphon breaking tube is lower than the height of the siphon tube.

[0012] In some embodiments, the pulse hood is fixed to the outer wall of the siphon tube by a plurality of legs, one end of which is fixed to the lower end of the pulse hood and the other end of which is fixed to the siphon tube.

[0013] In some embodiments, the lower end of the siphon tube is fixed with a first connecting flange, and the upper end of the drainage main tube is provided with a second connecting flange that mates with the first connecting flange.

[0014] In some embodiments, the lower end of the main drainage pipe is provided with a water outlet whose inner diameter gradually decreases along the water outlet direction.

[0015] In some embodiments, the upper part of the water storage tank is connected to a water inlet pipe.

[0016] In some of these embodiments, the water storage tank is fixed to the upper end of the sludge storage tank by multiple support legs.

[0017] In some embodiments, the plurality of diffuser branches are spaced apart around the lower end of the main drainage pipe and extend radially along the bottom of the sludge storage tank.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] 1. When the water level in the reservoir reaches a certain height, the pulse generator instantly draws a large amount of water from the reservoir through the siphon pipe due to the siphon effect. The water is then discharged from the bottom of the sludge storage tank through the pulse diffuser, which flushes up the sludge at the bottom of the tank and prevents the sludge from hardening at the bottom of the sludge storage tank.

[0020] 2. This agitator requires no power drive and no additional water source. It can stir the sludge at the bottom of the sludge storage tank through the pulse diffuser. Since there is no mechanical moving mechanism, it can achieve lifetime maintenance-free operation, reducing operating costs. Attached Figure Description

[0037] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0038] See Figure 1 The above is a schematic diagram of the structure of an embodiment of the present utility model, which provides a non-powered pulse agitator, including a water storage tank 1, a pulse generator 2 disposed in the water storage tank 1, and a pulse diffuser 3 connected to the pulse generator 2 and extending to the bottom of the mud storage tank 4.

[0039] A water storage tank 1 is installed above the sludge storage tank to temporarily store the sludge-water mixture. It is paired with a pulse generator 2 to provide the conditions for pulse generation. The volume and dimensions of the water storage tank 1 determine the pulse volume and the pulse frequency period. In this example, the water storage tank 1 is fixed to the cover plate at the top of the sludge storage tank 4 by multiple support legs 7. An inlet pipe 6 is connected to the upper part of the water storage tank 1 to receive the sludge-water mixture that needs to be dewatered after treatment at the wastewater treatment plant.

[0040] like Figure 2 and Figure 3 As shown, the pulse transmitter 2 includes a siphon pipe 2-1 fixed on the water storage tank 1 and extending to the outside of the water storage tank 1 at its lower end, a pulse cover 2-2 fixed on the outer wall of the siphon pipe 2-1 and covering the siphon pipe 2-1, and a siphon breaking component fixed along the inner wall of the pulse cover 2-2. The upper end of the siphon breaking component is close to the top of the pulse cover 2-2 and the lower end extends to the lower part of the pulse cover 2-2 and protrudes out of the outer side of the cover wall. The lower end of the siphon breaking component is an air inlet and the upper end is an air outlet.

[0041] The siphon breaking assembly includes two siphon breaking pipes 2-3 symmetrically arranged on both radial sides of the pulse cover 2-2. The diameter of the siphon breaking pipe 2-3 is smaller than that of the siphon pipe 2-1. The siphon pipe 2-1 is a large-diameter round pipe that passes through the bottom plate of the water storage tank 1 and extends to the bottom of the water storage tank 1. The outer wall of the siphon pipe 2-1 is sealed and welded to the bottom plate of the water storage tank 1. The siphon breaking pipe 2-3 is a small-diameter square pipe, and its main body is welded and fixed to the inner wall of the pulse cover 2-2. The lower end of the siphon breaking pipe 2-3 is bent and passes through a perforation at the bottom of the pulse cover 2-2 and is welded and fixed to the outer wall of the pulse cover 2-2. Preferably, the height of the upper end of the siphon breaking pipe 2-3 is lower than that of the siphon pipe 2-1. When the water level in the water storage tank 1 drops to the air inlet position, air enters the pulse cover 2-2 through the siphon breaking pipe 2-3 to break the siphon effect.

[0042] The pulse cover 2-2 is a hollow columnar structure with an arc-shaped top. The pulse cover 2-2 is fixed to the outer wall of the siphon tube 2-1 by multiple legs 5. One end of each leg 5 is welded to the lower end of the pulse cover 2-2 and the other end is welded to the siphon tube 2-1. In this example, the pulse cover 2-2 is fixed to the outer wall of the siphon tube 2-1 by four legs 5 that are evenly spaced along the axial direction of the siphon tube 2-1.

[0043] like Figure 4As shown, the pulse diffuser 3 includes a main drainage pipe 3-1 connected to the siphon pipe 2-1 and multiple diffusion branch pipes 3-2 connected to the main drainage pipe 3-1. Multiple water outlets are provided on the side of the diffusion branch pipes 3-2 facing the bottom of the sludge storage tank 4. Preferably, the multiple diffusion branch pipes 3-2 are arranged at intervals around the lower end of the main drainage pipe 3-1 and extend radially along the bottom of the sludge storage tank 4. The number and length of the diffusion branch pipes 3-2 are reasonably distributed according to the shape and size of the tank, and they are arranged at a height of approximately 20 cm from the bottom surface of the tank. Water from the main drainage pipe 3-1 is distributed to various directions of the tank bottom through each diffusion branch pipe 3-2 and ejected from the water outlets, impacting the bottom surface of the tank.

[0044] To facilitate the connection between the main drainage pipe 3-1 and the siphon pipe 2-1, a first connecting flange 9 is provided at the lower end of the siphon pipe 2-1, and a second connecting flange 10 that mates with the first connecting flange 9 is provided at the upper end of the main drainage pipe 3-1.

[0045] A sludge collection pit 4-1 is provided at the inlet of the sludge discharge pipe 8 at the bottom of the sludge storage tank 4. Sludge is more likely to accumulate here. Therefore, an outlet head 3-1a with an inner diameter that gradually decreases along the direction of water discharge is provided at the lower end of the main diversion pipe 3-1, so that the sludge in the sludge collection pit 4-1 is flushed up by the strong water flow and cannot be deposited.

[0046] The working principle of this utility model is as follows:

[0047] After treatment at the wastewater treatment plant, the sludge-water mixture requiring dewatering enters the storage tank 1 through the inlet pipe 6. When the liquid level in the storage tank 1 is higher than the upper end of the siphon pipe 2-1, wastewater overflows from the top of the siphon pipe 2-1, simultaneously carrying away the air at the top of the pulse hood 2-2. This creates a negative pressure at the top of the pulse hood 2-2, causing wastewater outside the pulse hood 2-2 to rush into the pulse hood 2-2 instantly under atmospheric pressure and be discharged from the siphon pipe 2-1 to the bottom of the sludge storage tank 4, flushing the sludge storage tank 4 and preventing sludge deposition. When the water level in the storage tank 1 drops to the air inlet position of the siphon breaking pipe 2-3, air enters the top of the pulse hood 2-2, breaking the siphon, and the siphon pipe 2-1 stops draining, ending one pulse cycle. This cycle repeats at a certain frequency, thus achieving a non-powered stirring effect.

[0048] In summary, this agitator can achieve non-powered mixing, reducing operating costs.

[0049] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
