Description

Technical Field

[0001] This utility model belongs to the field of settling tank technology, and in particular relates to an anti-clogging mother liquor settling tank. Background Technology

[0002] Mother liquor settling tanks are common equipment in water treatment and chemical industries. They are mainly used to separate suspended solids from mother liquor. Their structure generally includes a tank body, inlet, outlet, and sludge discharge port. The tank body is usually cylindrical or rectangular, and may have internal baffles to optimize water flow. The working principle utilizes gravity. When mother liquor enters through the inlet, the water flow velocity slows down, and suspended solids gradually settle to the bottom of the tank under gravity. Clean water flows out from the outlet, thus achieving solid-liquid separation. It plays an important role in treating various liquids containing suspended solids, effectively improving liquid purity and providing favorable conditions for subsequent processes. However, existing mother liquor settling tanks may experience sludge discharge port blockage. If not cleaned promptly, the solid-liquid separation effect at the outlet may be compromised. Utility Model Content

[0003] In view of this, the present invention aims to propose an anti-clogging mother liquor settling tank to solve the problem of inconvenient cleaning and unblocking operation when the sludge discharge port of the existing mother liquor settling tank is blocked.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A clog-resistant mother liquor settling tank includes a tank body. An inlet pipe and an outlet pipe are located above the tank body, and a discharge pipe and a sludge discharge pipe are located below the tank body. The sludge discharge pipe is vertically mounted on the tank body. A clog-clearing mechanism is located above the tank body corresponding to the position of the sludge discharge pipe. The clog-clearing mechanism includes an air supply pipe, a receiving pipe, and a clearing rod. The receiving pipe is vertically mounted inside the tank body and is positioned corresponding to the sludge discharge pipe. One end of the air supply pipe extends into the receiving pipe, and the other end is connected to an external air supply device. An assembly hole for the air supply pipe is located on the tank body corresponding to the position of the receiving pipe. One end of the clearing rod extending into the receiving pipe has an air jet pipe, and the other end has a conical end for extending into the sludge discharge pipe. At least two air jet pipes are evenly arranged along the circumference of the clearing rod, each air jet pipe being obliquely upward on the clearing rod. An air guiding cavity is provided inside the clearing rod for connecting the air supply pipe and the air jet pipe. The downward-sloping end of the air jet pipe communicates with the air guiding cavity, and the upward-sloping end has an air jet port.

[0006] Furthermore, the unblocking rod is provided with a rolling element that can cooperate with the inner wall of the receiving pipe. At least two rolling elements are evenly arranged along the circumference of the unblocking rod, and each rolling element is rotatably mounted on the unblocking rod.

[0007] Furthermore, one end of the jet pipe is fixed to the unblocking rod, and the other end is provided with a bend.

[0008] Furthermore, one end of the gas supply pipe extending out of the tank is connected to an external gas supply device via a flexible gas guide hose, and the flexible gas guide hose and the gas supply pipe are connected by a rotary joint.

[0009] Furthermore, the end of the unblocking rod extending out of the receiving tube is also equipped with an agitator.

[0010] Furthermore, the jet pipe is positioned above the air guide cavity and below the air guide cavity at the conical end.

[0011] Furthermore, the end of the receiving tube facing the sludge discharge pipe is provided with a limiting ring for limiting the jet pipe.

[0012] Furthermore, the end of the receiving pipe facing the sludge discharge pipe is provided with a horn cover, the small diameter end of the horn cover is connected to the receiving pipe, and the large diameter end is set towards the sludge discharge pipe.

[0013] Compared with the prior art, the anti-clogging mother liquor settling tank of this utility model has the following advantages:

[0014] This utility model discloses an anti-clogging mother liquor settling tank, which has the advantages of being less prone to clogging, easy to use and maintain. It can be connected to an external air supply device to clear blockages in the sludge discharge pipe, simplifying operation and improving the reliability and stability of the mother liquor settling tank. By installing an angled jet pipe on the unclogging rod, airflow is sprayed obliquely upwards from the jet nozzle. This not only pushes the unclogging rod into the sludge discharge pipe, discharging the blocked sludge, but also allows the gas entering the receiving pipe to flow downwards, continuously blowing the sludge towards the discharge pipe, accelerating its discharge. This simultaneously clears blockages in the discharge pipe and drives rapid sludge discharge, resulting in a better unclogging effect. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A type of anti-clogging mother liquor settling tank, such as Figures 1 to 3As shown, the device includes a tank body 1. An inlet pipe 2 and an outlet pipe 3 are located above the tank body 1, and a discharge pipe 4 and a sludge discharge pipe 5 are located below the tank body 1. The sludge discharge pipe 5 is vertically mounted on the tank body 1. A blockage-clearing mechanism is located above the tank body 1 corresponding to the position of the sludge discharge pipe 5. The blockage-clearing mechanism includes an air supply pipe 7, a receiving pipe 6, and a clearing rod 10. The receiving pipe 6 is vertically mounted inside the tank body 1 and is positioned corresponding to the sludge discharge pipe 5. One end of the air supply pipe 7 extends into the receiving pipe 6, and the other end is connected to an external air supply device. A clearing rod 10 is located on the tank body 1 corresponding to the position of the receiving pipe 6. The position is provided with an assembly hole that mates with the air supply pipe 7; one end of the unblocking rod 10 that extends into the receiving pipe 6 is provided with an air jet pipe 11, and the other end is provided with a conical end 13 for extending into the sludge discharge pipe 5. At least two air jet pipes 11 are evenly arranged around the circumference of the unblocking rod 10, and each air jet pipe 11 is obliquely upward on the unblocking rod 10. The unblocking rod 10 is provided with an air guiding cavity 16 for connecting the air supply pipe 7 and the air jet pipe 11. The obliquely downward end of the air jet pipe 11 is connected to the air guiding cavity 16, and the obliquely upward end is provided with an air jet port 18.

[0026] For example, the feed pipe 2, exhaust pipe 3, discharge pipe 4, sludge discharge pipe 5, and receiving pipe 6 are all fixed to the tank body 1. Among them, two, three, or more jet pipes 11 can be evenly arranged, and each jet pipe 11 is fixed to the unblocking rod 10. The air supply pipe 7 is also fixed to the unblocking rod 10 so as to supply air to the jet pipe 11 through the air guiding cavity 16.

[0027] In actual use, when the sludge discharge pipe 5 becomes blocked, the operator can supply air to the air supply pipe 7 through an external air supply device. After the airflow enters the air guide cavity 16 through the air supply pipe 7, the airflow will be sprayed obliquely upward from the air outlet 18 of the air jet pipe 11. This not only pushes the unblocking rod 10 into the sludge discharge pipe 5 and pushes the blocked sludge in the sludge discharge pipe 5 out, but also the gas entering the receiving pipe 6 can flow downward through the receiving pipe 6, continuously blowing the sludge towards the sludge discharge pipe 5, so that the sludge can be discharged more quickly. This can simultaneously clear the blockage of the sludge discharge pipe 5 and drive the sludge to be discharged quickly, resulting in a better unblocking effect.

[0028] Preferably, the drain rod 10 is provided with a rolling element 12 that can cooperate with the inner wall of the receiving tube 6. At least two rolling elements 12 are evenly arranged along the circumference of the drain rod 10, and each rolling element 12 is rotatably mounted on the drain rod 10. For example, two, three or more rolling elements 12 can be evenly arranged. The rolling elements 12 can be rollers or balls. The drain rod 10 is fixed with a mounting seat for mounting the rolling elements 12. For example, the mounting seat can be a wheel frame that cooperates with the roller, or a ball seat that cooperates with the ball.

[0029] In practical applications, by uniformly arranging multiple rolling elements 12 around the circumference of the unblocking rod 10, the friction between the unblocking rod 10 and the inner wall of the receiving pipe 6 can be reduced by the rotation of the rolling elements 12. At the same time, the multiple rolling elements 12 can also play a good guiding and limiting role for the unblocking rod 10, ensuring that the unblocking rod 10 always moves up and down stably.

[0030] Preferably, one end of the jet pipe 11 is fixed to the unblocking rod 10, and the other end is provided with a bend 17. Specifically, the jet nozzle 18 is provided on the bend 17. The bend 17 on the jet pipe 11 can form a structure similar to a rotating nozzle, so that the airflow passing through the jet nozzle 18 can not only be sprayed upward to push the unblocking rod 10 downward, but also drive the unblocking rod 10 to rotate, which is beneficial to improving the unblocking effect of the unblocking rod 10 on the sludge discharge pipe 5.

[0031] In practical applications, the end of the unclogging rod 10 extending out of the receiving pipe 6 is also equipped with an agitator 14. Specifically, the agitator 14 can be a spiral blade, and the agitator 14 is fixed on the unclogging rod 10. By setting the agitator 14 on the unclogging rod 10, the rotating agitator 14 can further loosen the stubborn sludge in the sludge discharge pipe 5, which helps to improve the unclogging speed when the sludge discharge pipe 5 is blocked.

[0032] Preferably, one end of the air supply pipe 7 extending from the tank body 1 is connected to an external air supply device via a flexible air guide hose 9. The flexible air guide hose 9 and the air supply pipe 7 are connected via a rotary joint 8. Specifically, the flexible air guide hose 9 can be a rubber hose, a stainless steel hose, etc. It should be noted that the flexible air guide hose 9 needs to have a spare length so that it can continuously supply air to the air supply pipe 7 when the air supply pipe 7 moves with the unblocking rod 10. In addition, conventional connection methods can be used between the flexible air guide hose 9 and the external air supply device, between the flexible air guide hose 9 and the rotary joint 8, and between the air supply pipe 7 and the rotary joint 8 to achieve air guidance, which will not be elaborated here. Those skilled in the art can also choose other connection and air supply methods according to actual needs to achieve continuous air supply to the jet pipe 11, which will also not be elaborated here.

[0033] Preferably, the jet pipe 11 is positioned above the air-guiding cavity 16, and the lower part of the air-guiding cavity 16 is positioned below the conical end 13. By positioning the jet pipe 11 in the upper part of the air-guiding cavity 16, when the air supply pipe 7 stops supplying air, the unblocking rod 10 can move upward under the buoyancy of the residual gas in the air-guiding cavity 16 and retract into the receiving pipe 6, facilitating subsequent unblocking operations. At this time, because the jet pipe 11 is located in the upper part of the air-guiding cavity 16, liquid in the tank 1 is less likely to enter the jet pipe 11 under the action of buoyancy, thereby effectively preventing external air supply equipment and air-guiding hose 9 from being corroded and damaged by liquid ingress.

[0034] Preferably, the end of the receiving pipe 6 facing the sludge discharge pipe 5 is provided with a limiting ring 19 for limiting the jet pipe 11. Exemplarily, the limiting ring 19 is fixed to the receiving pipe 6, and the inner diameter of the limiting ring 19 is smaller than the outer diameter of each jet pipe 11, ensuring that the limiting ring 19 can effectively limit the jet pipe 11. In actual use, by using the limiting ring 19 to limit the jet pipe 11, the jet pipe 11 can be prevented from moving out of the receiving pipe 6, ensuring that the unblocking rod 10 can be retracted into the receiving pipe 6 under the action of buoyancy.

[0035] Preferably, a horn cover 15 is provided at the end of the receiving pipe 6 facing the sludge discharge pipe 5. The small-diameter end of the horn cover 15 is connected to the receiving pipe 6, and the large-diameter end is set towards the sludge discharge pipe 5. For example, the horn cover 15 is fixed on the receiving pipe 6. By providing the horn cover 15, it is beneficial to improve the pushing effect of the airflow discharged through the receiving pipe 6 on the sludge, and further accelerate the movement of the sludge towards the sludge discharge pipe 5.

[0036] This utility model discloses an anti-clogging mother liquor settling tank, which has the advantages of being less prone to clogging, easy to use and maintain. It can be connected to an external air supply device to clear blockages in the sludge discharge pipe, simplifying operation and improving the reliability and stability of the mother liquor settling tank. By installing an angled jet pipe on the unclogging rod, airflow is sprayed obliquely upwards from the jet nozzle. This not only pushes the unclogging rod into the sludge discharge pipe, discharging the blocked sludge, but also allows the gas entering the receiving pipe to flow downwards, continuously blowing the sludge towards the discharge pipe, accelerating its discharge. This simultaneously clears blockages in the discharge pipe and drives rapid sludge discharge, resulting in a better unclogging effect.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
