Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, and specifically relates to a carrier recovery device. BACKGROUND

[0002] In the modern sewage treatment technology system, the multi-effect clarification system is the key link for realizing efficient purification of sewage, and the carrier plays an indispensable role, and the carrier is used for assisting in forming flocculation and accelerating precipitation, and the cyclone of the carrier is used as a kind of equipment for realizing separation of two-phase or multi-phase fluid by using centrifugal field, and its core component cyclone plays a key role in various industries.

[0003] The cyclone structure of the existing carrier recovery device is not sufficient for the separation of different density materials, only relies on simple cylinder and basic inlet and outlet structure, and it is difficult to meet the efficient separation demand of complex component sludge, for example, when treating sludge containing multiple different density carriers and impurities, due to unreasonable flow channel design of the cyclone, part of large-density coarse-grained materials cannot be completely separated to underflow pipe, but moves upward along internal cyclone and mixes into fine-grained materials discharged from overflow pipe, similarly, some small-density fine-grained materials also enter underflow due to incomplete separation, which causes cross contamination of carriers and impurities, and reduces the quality of carrier recovery and subsequent reuse value. SUMMARY

[0004] The utility model aims at providing a kind of carrier recovery device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of carrier recovery device, comprising:

[0006] Base, the base is connected with mounting bracket, the mounting bracket is installed with cyclone, the cyclone includes cylinder and the feed cylinder connected by sealing flange, the feed cylinder top is equipped with overflow pipe for discharging small-density fine-grained material, the cylinder bottom is equipped with underflow pipe for discharging large-density coarse-grained material, the cylinder and underflow pipe are also connected with several conical cylinders by several sealing flanges;

[0007] Feed interface, the feed interface is connected on feed cylinder, for ensuring that sludge flows smoothly into cyclone.

[0008] Preferably, the other end of the feed interface is connected with feed pipe through feed flange.

[0009] Preferably, the bottom of the conical cylinder is also connected with the underflow pipe through the sealing flange.

[0010] Preferably, the top of the feed cylinder is connected with the overflow pipe through the overflow flange.

[0011] Preferably, the top of the feed inlet is equipped with a pressure gauge and a lifting ring.

[0012] Preferably, the liner of the cyclone is a KM wear-resistant ceramic composite material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The inner lining of the hydrocyclone is made of KM wear-resistant ceramic composite material. This material has the characteristics of high hardness and high wear resistance. Compared with traditional materials, it can effectively resist the scouring of impurities in the carrier sludge. During the transportation of carrier sludge, the friction and impact of impurities on the inner wall of the hydrocyclone will be buffered and resisted by the wear-resistant ceramic composite material, which greatly reduces the wear of the hydrocyclone and thus extends the service life of the hydrocyclone and the entire hydrocyclone.

[0015] (2) Several cones are connected between the cylinder and the underflow pipe. This design optimizes the flow channel of centrifugal separation. When the sludge containing the carrier enters the cyclone, under the action of centrifugal force, the high-density coarse particles and the low-density fine particles can move more smoothly to the underflow pipe and the overflow pipe respectively. The presence of the cones increases the movement path and time of the material in the cyclone, making the separation of materials of different densities more complete, thereby improving the carrier recovery efficiency, ensuring that more carriers can be effectively recycled and reused, and reducing resource waste.

[0016] (3) The pressure gauge at the top of the feed interface can monitor the feed pressure in real time. Operators can adjust the conveying pressure of the sludge pump in a timely manner according to the pressure data to avoid damage to the equipment due to excessive pressure. At the same time, it ensures that the cyclone operates at the optimal working pressure and improves the separation effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figs. 1-2 The carrier recycling device shown includes:

[0022] A base 1 is provided, and a mounting frame 2 is connected to the base 1. A cyclone separator 3 is installed inside the mounting frame 2. The cyclone separator 3 includes a cylinder 4 and a feed cylinder 5 connected by a sealing flange 9. The top of the feed cylinder 5 is provided with an overflow pipe 6 for discharging low-density fine particles, and the bottom of the cylinder 4 is provided with an underflow pipe 7 for discharging high-density coarse particles. Several cones 12 are also connected between the cylinder 4 and the underflow pipe 7 by several sealing flanges 9. The cones 12 can reasonably guide the flow of slurry and avoid sudden pressure changes and excessive local pressure.

[0023] Feed port 8 is connected to the feed cylinder 5 to ensure that sludge flows smoothly into the cyclone separator 3.

[0024] The other end of the feed port 8 is connected to the feed pipe 11 via the feed flange 10.

[0025] The bottom of the cone 12 is also connected to the underflow pipe 7 via the sealing flange 9, and the top of the feed cylinder 5 is connected to the overflow pipe 6 via the overflow flange 13. When the overflow flange 13 and the sealing flange 9 are connected, sealing gaskets are installed between the flanges. These sealing gaskets can effectively fill the tiny gaps between the flanges and prevent fluid from seeping out from the connection.

[0026] The top of the feed inlet 8 is equipped with a pressure gauge 14 and a lifting ring 15. The pressure gauge 14 can monitor the feed pressure in real time, and the operator can intuitively obtain the pressure data. Once the pressure fluctuates abnormally, the operating parameters of the sludge pump used to transport the sludge can be adjusted in time.

[0027] The liner of the cyclone 3 is KM wear-resistant ceramic composite material. KM wear-resistant ceramic composite material has high hardness and wear resistance, which can effectively resist the erosion of materials and ensure the long-term stable operation of the cyclone 3.

[0028] This carrier recovery device transports a mixed slurry containing various carriers and impurities through a pipeline system, driven by a sludge pump, to the inlet pipe 11. Once inside the inlet pipe 11, the slurry flows into the inlet interface 8, which acts as a transition and distribution point, guiding the slurry evenly to the feed cylinder 5. During this process, the pressure gauge 14 at the top of the inlet interface 8 begins to function, monitoring the slurry pressure entering the device in real time. This pressure monitoring allows operators to understand the current inlet pressure and adjust the sludge pump's operating parameters accordingly. Excessive pressure may cause excessive impact and wear on internal components; insufficient pressure may prevent the slurry from forming an effective vortex within the device, affecting separation efficiency. The slurry enters the cylinder 4 of the cyclone separator 3 from the feed cylinder 5 using a tangential or... The involute feeding method allows the slurry to quickly form a high-speed rotating motion after entering the cylinder 4. When the slurry enters the cylinder 4 in a tangential or involute direction, it will make a circular motion along the inner wall of the cylinder 4, thereby generating a strong centrifugal force field. Under the action of this centrifugal force field, the different components in the mixed slurry begin to separate according to their density differences. The coarse particles with higher density, such as gypsum particles, larger impurities, and some carriers, are subjected to greater centrifugal force and will gradually move towards the outer peripheral wall of the cylinder 4. As the slurry continues to rotate, these coarse particles will move downward with the outer swirling flow and gather towards the underflow pipe 7. The fine particles with lower density, such as smaller carrier particles, fine impurities, and some liquids, are subjected to relatively smaller centrifugal force. They will move upward under the action of the inner swirling flow formed in the central low-pressure zone and gradually approach the overflow pipe 6.

[0029] Several cones 12 are connected between the cylinder 4 of the cyclone separator 3 and the underflow pipe 7. These cones 12 play a key role in enhancing the separation effect during the separation process. When the outer cyclone carries coarse particles downward into the cone 12, the rotation speed of the slurry will be further accelerated as the inner diameter of the cone 12 gradually decreases. This allows the coarse particles, which may have been mixed with some fine particles, to be separated more fully. The coarse particles will move closer to the wall of the cone 12 and be further separated from the fine particles. As the outer cyclone continues to flow downward, the coarse particles will eventually be discharged from the cyclone separator 3 through the underflow pipe 7, thus achieving effective separation and recovery of high-density coarse particles.

[0030] While being discharged through the underflow pipe 7, the fine particulate material carried by the internal vortex will continue to move upward and eventually be discharged through the overflow pipe 6. These fine particulate materials contain some small carrier particles that need further processing or recycling, as well as some liquid and fine impurities. The material discharged through the overflow pipe 6 can be further processed according to the needs of subsequent processes.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
