Description

Technical Field

[0001] The present disclosure relates to the field of sewage treatment equipment, and in particular to a fluid dosing and mixing device and a fluid dosing system. Background Art

[0002] With the improvement of my country's sewage treatment rate and treatment capacity, the amount of sludge generated has also increased, showing an increasing trend year by year. Compared with sewage treatment, the capacity and level of sludge treatment and disposal are relatively backward, and the environmental risks are more severe.

[0003] In order to reduce the amount of sludge and the amount of sludge transported, the current sludge treatment process requires the excess sludge to be collected through the sludge pipeline and transported to the sludge dewatering machine for concentration and dehydration. In this process, multiple agents need to be added for joint conditioning to improve the dehydration effect. The usual practice is to add sludge conditioners first and then coagulants. The length of time the dehydrating agent reacts with the sludge and the mixing efficiency can directly affect the dehydration effect.

[0004] In addition, the order of adding different reagents also has a great influence on the dehydration effect. In addition, for some reagents, after the optimal dosage is determined, they need to be added in batches and stirred continuously, and they can be put into use after being completely mixed. In the actual operation process, different reagents are often added at the same time and mixed with the sludge at the same time, resulting in a short mixing time between the reagents and the sludge, which will affect the effect of the reagents.

[0005] The mud-drug mixing device commonly used in sewage treatment plants consists of a dosing device and a mixer. When the dewatering machine is running, the dissolved agent is pumped to the dosing device and enters the sludge pipeline. The agent and sludge flow into the mixer to form a jet and swirl mixture, and then flow to the dewatering machine for concentration and dehydration. Due to the short mixing time from the mixer to the dewatering machine, insufficient and uneven mixing, the mud-drug mixing effect is poor and the efficiency is low. Good flocs cannot be formed, which affects the dehydration effect and increases the cost of sludge treatment. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the present disclosure provides a fluid dosing mixing device and a fluid dosing system.

[0007] According to a first aspect of the present disclosure, there is provided a fluid dosing and mixing device, comprising: a mixing conduit configured to contain a fluid configured to flow in a first direction along the mixing conduit; A drug administration device, the drug administration device comprising a drug administration component and a drug supply component, the drug supply component being configured to be connected to the drug administration component through a drug supply tube to provide a drug to the drug administration component; The drug administration assembly includes a blocking member, wherein the blocking member is provided with a blocking surface and an impact surface, wherein the impact surface faces the first direction, and the blocking surface faces the second direction, and the second direction is the opposite direction of the first direction; The outlet of the drug supply tube is configured to face the impact surface, so that the medicine disperses and flows around the impact surface and then mixes with the fluid.

[0008] In one embodiment of the present disclosure, the blocking member is constructed to be spherical, and the outer circumference of the spherical shape faces the second direction, and the inner circumference of the spherical shape faces the first direction; the outlet of the medicine supply tube is constructed to face the second direction.

[0009] In one embodiment of the present disclosure, the drug supply tube has a drug supply terminal section extending along the second direction.

[0010] In one embodiment of the present disclosure, the medicine supply terminal section is constructed as a variable diameter section whose inner diameter continuously decreases along the flow direction of the medicine solution.

[0011] In one embodiment of the present disclosure, a plurality of tooth-like protrusions are provided on the circumferential outer edge of the blocking member, and the tooth-like protrusions are configured to be evenly distributed along the circumferential outer edge of the blocking member.

[0012] In one embodiment of the present disclosure, the fluid dosing and mixing device includes a fixed frame; the fixed frame is configured to be fixedly disposed in the mixing pipe and is provided with a flow opening along the first direction; the drug supply tube is configured to be fixedly disposed on the fixed frame.

[0013] In one embodiment of the present disclosure, the fluid dosing and mixing device further comprises a yoke arm, a first end of the yoke arm is fixedly disposed on the fixing frame, and a second end of the yoke arm is fixed on the blocking member.

[0014] In one embodiment of the present disclosure, in the projection along the first direction, the projection of the blocking member completely covers the projection of the yoke arm.

[0015] According to a second aspect of the present disclosure, a fluid dosing system is provided, comprising at least two of the fluid dosing mixing devices, wherein the mixing pipes of the fluid dosing mixing devices are connected in sequence.

[0016] In one embodiment of the present disclosure, the corresponding drugs of the drug administration devices in the fluid drug administration and mixing devices are not completely the same.

[0017] During the operation of the fluid dosing and mixing device disclosed in the present invention, the fluid to which the medicine needs to be added flows in the mixing pipe along the first direction; the medicine supply component supplies medicine to the dosing component through the medicine supply pipe, wherein, since the outlet of the medicine supply pipe faces the impact surface, after the medicine flows out of the medicine supply pipe, it disperses and flows around on the impact surface, and continues to flow in the first direction after being thoroughly mixed with the fluid, and then performs corresponding chemical reactions with related substances in the fluid. Since the impact surface of the blocking member faces the first direction, the flow of the fluid can be effectively blocked, preventing the fluid from flowing to the outlet of the medicine supply pipe, and avoiding the fluid from flowing back to the medicine supply pipe, effectively ensuring the normal operation of the fluid dosing and mixing device disclosed in the present invention.

[0018] It can be seen that the fluid dosing and mixing equipment disclosed in the present invention can effectively mix the fluid and the medicine evenly, improve the mixing efficiency, thereby improving the effect of the medicine, and can effectively prevent the fluid from flowing back to the medicine supply pipe, prevent the medicine supply pipe from being blocked, and ensure the normal medicine supply of the medicine supply pipe.

[0028] The present disclosure provides a fluid dosing and mixing device, which includes a mixing pipe and a dosing device; wherein the mixing pipe is configured to contain a fluid, and the fluid is configured to flow along a first direction of the mixing pipe; the dosing device includes a dosing component and a drug supply component, and the drug supply component is configured to be connected to the dosing component through a drug supply pipe to provide medicine to the dosing component; the dosing component includes a blocking member, and the blocking member is provided with a blocking surface and an impact surface, the impact surface faces the first direction, and the blocking surface faces the second direction, and the second direction is the opposite direction of the first direction; the outlet of the drug supply pipe is configured to face the impact surface, so that the medicine can disperse and flow around on the impact surface and then mix with the fluid.

[0029] Therefore, during the operation of the fluid dosing and mixing device disclosed in the present invention, the fluid to which the medicine needs to be added flows in the mixing pipe along the first direction; the medicine supply component supplies medicine to the dosing component through the medicine supply pipe, wherein, since the outlet of the medicine supply pipe faces the impact surface, after the medicine flows out of the medicine supply pipe, it disperses and flows around on the impact surface, and continues to flow in the first direction after being thoroughly mixed with the fluid, and then reacts chemically with the relevant substances in the fluid. Since the impact surface of the blocking member faces the first direction, the flow of the fluid can be effectively blocked, preventing the fluid from flowing to the outlet of the medicine supply pipe, avoiding the fluid from flowing back to the medicine supply pipe, and effectively ensuring the normal operation of the fluid dosing and mixing device disclosed in the present invention.

[0030] It can be seen that the fluid dosing and mixing equipment disclosed in the present invention can effectively mix the fluid and the medicine evenly, improve the mixing efficiency, thereby improving the effect of the medicine, and can effectively prevent the fluid from flowing back to the medicine supply pipe, prevent the medicine supply pipe from being blocked, and ensure the normal medicine supply of the medicine supply pipe.

[0031] For ease of understanding, refer to Figure 1 , the specific structure and working principle of the fluid dosing mixing device and the fluid dosing system disclosed in the present invention are explained in detail in combination with an embodiment.

[0032] like Figure 1 As shown, the present disclosure provides a fluid dosing and mixing device, which includes a mixing pipe 1 and a dosing device; wherein the mixing pipe 1 is configured to contain a fluid, and the fluid is configured to flow along a first direction of the mixing pipe 1; the dosing device includes a dosing component and a drug supply component, and the drug supply component is configured to be connected to the dosing component through a drug supply pipe 2 to provide a drug to the dosing component; The drug administration assembly includes a blocking member 3, wherein the blocking member 3 is provided with a blocking surface and an impact surface, wherein the impact surface faces a first direction, and the blocking surface faces a second direction, and the second direction is the opposite direction of the first direction; The outlet of the medicine supply tube 2 is arranged to face the impact surface, so that the medicine disperses and flows around the impact surface and mixes with the fluid.

[0033] Therefore, during the operation of the fluid dosing and mixing device disclosed in the present invention, the fluid to which the medicine needs to be added flows along the first direction in the mixing pipe 1; the medicine supply assembly supplies medicine to the dosing assembly through the medicine supply pipe 2, wherein, since the outlet of the medicine supply pipe 2 faces the impact surface, after the medicine flows out of the medicine supply pipe 2, it disperses and flows around on the impact surface, and continues to flow along the first direction after being thoroughly mixed with the fluid, and then reacts with the relevant substances in the fluid. Since the impact surface of the blocking member 3 faces the first direction, the flow of the fluid can be effectively blocked, preventing the fluid from flowing to the outlet of the medicine supply pipe 2, avoiding the fluid from flowing back to the medicine supply pipe 2, and effectively ensuring the normal operation of the fluid dosing and mixing device disclosed in the present invention.

[0034] It can be seen that the fluid dosing and mixing equipment disclosed in the present invention can effectively mix the fluid and the medicine evenly, improve the mixing efficiency, thereby improving the effect of the medicine, and can effectively prevent the fluid from flowing back to the medicine supply pipe 2, prevent the medicine supply pipe 2 from being blocked, and ensure the normal medicine supply of the medicine supply pipe 2.

[0035] It can be understood that the fluid dosing and mixing device disclosed in the present invention can be used to feed sludge in sewage treatment equipment, and can also be used to feed sewage or other forms of fluids, without limitation herein.

[0036] like Figure 1 As shown, in one embodiment of the present disclosure, the blocking member 3 is constructed to be spherical, and the outer circumference of the spherical shape faces the second direction, and the inner circumference of the spherical shape faces the first direction; the outlet of the medicine supply tube 2 is constructed to face the second direction.

[0037] Since the blocking member 3 is spherical, and the outer circumferential surface of the spherical shape faces the second direction, the inner circumferential surface of the spherical shape faces the first direction, and the outlet of the medicine supply tube 2 faces the second direction, on the one hand, when the fluid flows to the outer circumferential surface of the spherical shape, it can not only flow along the outer circumferential surface of the spherical shape, thereby bypassing the medicine supply tube 2, but also the outer circumferential surface of the spherical shape will not cause the fluid to lose a large amount of kinetic energy, thereby effectively reducing the kinetic energy loss of the fluid; on the other hand, when the medicine hits the inner circumferential surface of the spherical shape along the second direction, it can evenly disperse and flow around, and then continue to flow along the first direction with the fluid after being thoroughly mixed with the fluid at the edge of the spherical shape, thereby ensuring uniform distribution of the medicine.

[0038] In another embodiment of the present disclosure, the blocking member 3 may also be in other shapes such as a truncated cone or a cone, which is not limited here.

[0039] like Figure 1As shown, in one embodiment of the present disclosure, the drug supply tube 2 has a drug supply terminal section extending along the second direction; because the drug supply tube 2 has a drug supply terminal section extending along the second direction, when the medicine flows along the drug supply tube 2, after flowing out from the drug supply terminal section extending along the second direction, it can effectively impact the impact surface of the blocking member 3, thereby allowing the medicine to evenly disperse and flow around.

[0040] Furthermore, in one embodiment of the present disclosure, the medicine supply terminal section is constructed as a variable diameter section with a continuously decreasing inner diameter along the flow direction of the medicine liquid. Since the medicine supply terminal section is a variable diameter section with a continuously decreasing inner diameter along the flow direction of the medicine liquid, when the medicine flows along the medicine supply tube 2, after flowing to the medicine supply terminal section, the flow rate will increase, so that the impact surface of the blocking member 3 is more evenly distributed around.

[0041] like Figure 1 As shown, in one embodiment of the present disclosure, the circumferential outer edge of the blocking member 3 is provided with a plurality of tooth-like protrusions 31, and the tooth-like protrusions 31 are constructed to be evenly distributed along the circumferential outer edge of the blocking member 3. Since the circumferential outer edge of the blocking member 3 is provided with a plurality of tooth-like protrusions 31, and each tooth-like protrusion 31 is evenly distributed along the circumferential outer edge of the blocking member 3, when the fluid flows along the blocking surface of the blocking member 3 to the corresponding position of the tooth-like protrusions 31, part of the fluid will flow into the gaps between each tooth-like protrusion 31, and similarly, when the medicine flows along the impact surface of the blocking member 3 to the corresponding position of the tooth-like protrusions 31, part of the medicine will also flow into the gaps between each tooth-like protrusion 31, thereby mixing with the fluid. According to actual measurements, by providing a plurality of evenly distributed tooth-like protrusions 31 on the circumferential outer edge of the blocking member 3, the mixing between the fluid and the medicine can be made more fully and evenly.

[0042] like Figure 1 As shown, in one embodiment of the present disclosure, the fluid dosing and mixing device includes a fixing frame 4; the fixing frame 4 is configured to be fixedly arranged in the mixing pipeline 1, and is arranged along the first direction with a flow opening; the drug supply pipe 2 is configured to be fixedly arranged on the fixing frame 4. That is, the drug supply pipe 2 can be effectively fixedly arranged in the mixing pipeline 1 through the fixing frame 4, and because the fixing frame 4 is arranged along the first direction with a flow opening, the fluid can continue to flow from the flow opening to the subsequent equipment after mixing with the drug liquid, and the fixing frame 4 will not hinder the flow of the fluid.

[0043] like Figure 1 As shown, in one embodiment of the present disclosure, the fluid dosing and mixing device further comprises a yoke arm 5, a first end of the yoke arm 5 is fixedly disposed on the fixing frame 4, and a second end of the yoke arm 5 is fixed on the blocking member 3. By providing the yoke arm 5, the blocking member 3 can be effectively fixed on the fixing frame 4 without the need for other structures to fix the blocking member 3.

[0044] Further, such as Figure 1As shown, in one embodiment of the present disclosure, in the projection along the first direction, the projection of the blocking member 3 completely covers the projection of the yoke arm 5. Since in the projection along the first direction, the projection of the blocking member 3 completely covers the projection of the yoke arm 5, when the fluid flows in the mixing pipe 1 along the first direction, it will only be blocked by the blocking member 3 and the fixing frame 4, and will not be blocked by the yoke arm 5, thereby effectively reducing the kinetic energy loss of the fluid.

[0045] The present disclosure also provides a fluid dosing system, which includes at least two of the aforementioned fluid dosing mixing devices, and the mixing pipes 1 of the various fluid dosing mixing devices are sequentially connected. During the flow of the fluid along the mixing pipe 1, each fluid dosing mixing device can add a corresponding agent into the fluid, thereby effectively achieving multi-point dosing and batch dosing, and improving the effect of the agent.

[0046] It is understandable that after the sludge is dosed, the sludge can enter the dehydrator for dehydration. Specifically, the mixing pipes 1 of each fluid dosing and mixing device can be connected to each other by flanges, bolts or clamps, which are not limited here.

[0047] Furthermore, in one embodiment of the present disclosure, the corresponding drugs of the dosing devices in each fluid dosing and mixing device are not completely the same. Since the corresponding drugs of the dosing devices in each fluid dosing and mixing device are not completely the same, the fluid dosing system of the present disclosure can put different types of drugs into the fluid, thereby effectively meeting the dosing needs.

[0048] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
