Description

Technical Field

[0001] This utility model relates to the field of expansion container technology, and in particular to a multi-stage anti-clogging sewage expansion container. Background Technology

[0002] Industrial production processes generate large amounts of wastewater and waste liquid, which typically contain various solid impurities, particles, and high concentrations of pollutants. In the power industry, boiler blowdowns discharge high-temperature, high-pressure wastewater containing large amounts of scale, rust, and other impurities. Chemical production wastewater may contain crystalline salts and polymer particles. Metallurgical wastewater often contains metal ions and suspended solids. Traditional wastewater treatment equipment faces numerous challenges in handling these complex industrial wastewaters. Firstly, single-stage blowdown expansion tanks, due to limited pressure reduction and separation effects, struggle to effectively treat high-solids, high-viscosity media, resulting in treated wastewater still containing many impurities and failing to meet environmental emission requirements or subsequent treatment processes. Secondly, traditional equipment has poor anti-clogging performance, allowing solid impurities to accumulate in pipes and filters, causing blockages that not only affect normal operation but also increase maintenance costs and downtime.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing sewage discharge equipment mostly adopts a single-stage filtration structure, such as a single-layer filter screen or a simple sieve plate, which cannot filter impurities of different sizes in sewage in layers. As a result, the treated sewage still contains a lot of suspended solids, making it difficult to meet strict environmental discharge standards or reuse requirements, and it cannot adapt to treatment scenarios with high solids content and complex water quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing sewage discharge equipment mostly adopts a single-stage filtration structure, which cannot filter impurities of different sizes in sewage in layers. To address this, we propose a multi-stage anti-clogging sewage discharge expansion container.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-stage anti-clogging sewage expansion container, including an expansion container, which is provided with multiple stages and the volume of each stage cavity increases progressively, forming a stepped pressure reduction space to ensure that the medium pressure is released gradually.

[0006] Preferably, the expansion container includes an outer shell, one end of which is provided with a connecting flange, which is fixedly connected to the delivery pipe by bolts. A cleaning assembly is installed through the outer side of the outer shell, and a collection box is installed at the lower end of the outer shell. Liquid is delivered into the interior of the expansion container through the delivery pipe. Due to the sudden increase in the volume of the cavity, the pressure drops instantaneously. Subsequently, the medium enters the next stage cavity in sequence, and the pressure decreases step by step until it is discharged at normal pressure. When the fluid flows through the outer shell, solid particles are filtered and collected by the collection box.

[0007] Preferably, the multi-stage expansion containers are connected by a conical connecting shell.

[0008] Preferably, a filter ball is fixedly installed inside the outer shell, and conical limiting shells are fixedly installed at both ends of the outer shell, with the cone apexes of the two sets of conical limiting shells arranged symmetrically.

[0009] Preferably, the collection box includes a collection shell, the upper opening of the collection shell is located directly below the filter ball, the collection shell is connected to the interior of the shell, the interior of the collection shell is provided with a partition, and a cleaning box is slidably provided on one side of the collection shell.

[0010] Preferably, the cleaning component includes a drive motor, the drive end of which passes through the outer shell and the filter ball, and a cleaning ring is fixedly installed on the drive end of the drive motor. The cleaning ring fits against the inner wall of the filter ball. After the expansion container has been used for a period of time, the drive motor is started to drive the cleaning ring to clean the inside of the filter ball, preventing the filter ball from becoming clogged and affecting the filtration effect.

[0011] Preferably, the filter ball is composed of a hemispherical mesh one and a hemispherical mesh two. The aperture of hemispherical mesh one is smaller than that of hemispherical mesh two. Hemispherical mesh two is located at the end near the inlet, and hemispherical mesh one is located at the end near the outlet. After the sewage enters the interior of the outer shell through the conical connecting shell, the sewage passes through the conical limiting shell, then through the filter ball for filtration, and then through the conical limiting shell for discharge. When the sewage passes through the conical limiting shell and the filter ball for the first time, some large particles of impurities are blocked through the outer side of hemispherical mesh two. The impurities fall into the interior of the cleaning box through the gap between hemispherical mesh two and the filter ball. At the same time, the filtered sewage flows into the interior of hemispherical mesh two for secondary filtration. Some small impurities are intercepted by hemispherical mesh one. The filtered small impurities fall into the cleaning box through the lower end of the filter ball for collection and treatment. Through multi-stage expansion tanks, the operation is repeated to deeply treat the impurities in the sewage and improve the sewage treatment efficiency.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a filter sphere composed of two hemispherical meshes, one hemispherical mesh and one hemispherical mesh, combined with a conical limiting shell, enables multi-stage filtration of wastewater. Large particles of impurities are first intercepted by the hemispherical mesh with the larger pore size, while fine impurities are then filtered by the hemispherical mesh. This multi-stage filtration process effectively treats impurities, significantly improving the wastewater treatment efficiency and purity compared to traditional single-stage filtration equipment.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1-2 As shown, this utility model provides a technical solution: a multi-stage anti-clogging sewage expansion container, including an expansion container 1. The expansion container 1 is provided with multiple stages, and the volume of each stage cavity increases progressively, forming a stepped pressure reduction space to ensure that the medium pressure is released gradually.

[0024] Reference Figure 2-3As shown in this embodiment: the expansion container 1 includes a shell 11, one end of which is provided with a connecting flange 111. The connecting flange 111 is fixedly connected to the delivery pipe by bolts. A cleaning assembly 12 is installed through the outer side of the shell 11. A collection box 13 is installed at the lower end of the shell 11. Liquid is delivered into the interior of the expansion container 1 through the delivery pipe. Due to the sudden increase in the volume of the cavity, the pressure drops instantaneously. Subsequently, the medium enters the lower cavity in sequence, and the pressure decreases step by step until it is discharged at normal pressure. When the fluid flows through the shell 11, solid particles are filtered and collected by the collection box 13.

[0025] Reference Figure 3-4 As shown in this embodiment, the multi-stage expansion containers 1 are connected by a conical connecting shell 112.

[0026] Reference Figure 4-5 As shown in this embodiment: a filter ball 14 is fixedly installed inside the outer shell 11, and conical limiting shells 113 are fixedly installed at both ends of the outer shell 11, with the cone apexes of the two sets of conical limiting shells 113 arranged symmetrically.

[0027] Reference Figure 4-5 As shown, in this embodiment: the collection box 13 includes a collection shell 131, the upper opening of the collection shell 131 is located directly below the filter ball screen 14, the collection shell 131 is connected to the interior of the shell 11, a partition 132 is provided inside the collection shell 131, and a cleaning box 133 is slidably provided on one side of the collection shell 131.

[0028] Reference Figure 3-5 As shown in this embodiment: the cleaning component 12 includes a drive motor 121, the drive end of the drive motor 121 passes through the outer shell 11 and the filter ball 14, and a cleaning ring 122 is fixedly installed on the drive end of the drive motor 121. The cleaning ring 122 is in contact with the inner wall of the filter ball 14. After the expansion container 1 has been used for a period of time, the drive motor 121 is started to drive the cleaning ring 122 to clean the inside of the filter ball 14, so as to prevent the filter ball 14 from becoming clogged and affecting the filtration effect.

[0029] Reference Figure 5-6As shown in this embodiment: the filter ball 14 is composed of a hemispherical mesh 141 and a hemispherical mesh 142. The aperture of the hemispherical mesh 141 is smaller than that of the hemispherical mesh 142. The hemispherical mesh 142 is located at one end near the inlet, and the hemispherical mesh 141 is located at one end of the outlet. After the sewage enters the interior of the outer shell 11 through the conical connecting shell 112, the sewage passes through the conical limiting shell 113 in sequence, then through the filter ball 14 for filtration, and then through the conical limiting shell 113 for discharge. At 14 o'clock, some large particles of impurities are blocked through the outer side of the hemispherical mesh 142. The impurities fall into the cleaning box 133 through the gap between the hemispherical mesh 142 and the filter ball 14. At the same time, the filtered sewage flows into the interior of the hemispherical mesh 142 for secondary filtration. Some small impurities are intercepted by the hemispherical mesh 141. The filtered small impurities fall into the cleaning box 133 through the lower end of the filter ball 14 for collection and treatment. The operation is repeated through the multi-stage expansion container 1 to deeply treat the impurities in the sewage and improve the sewage treatment efficiency.

[0030] Working principle: Wastewater enters the expansion container 1 through the connecting flange 111. In the multi-stage chamber, the pressure drops instantaneously due to the sudden increase in volume. Subsequently, the medium enters the next stage chamber in sequence, and the pressure decreases step by step until it is discharged at normal pressure. When the wastewater flows through the outer shell 11, large particles of impurities are first intercepted by the hemispherical mesh 142. The large particles of impurities fall into the cleaning box 133 through the gap between the mesh and the filter ball 14. The filtered wastewater is then filtered a second time by the hemispherical mesh 141. Fine impurities fall into the cleaning box 133 through the lower end of the filter ball 14. At the same time, after a period of use, the drive motor 121 drives the cleaning ring 122 to clean the inside of the filter ball 14 to prevent clogging. The whole process is repeated through the multi-stage expansion container 1 to achieve deep treatment of wastewater impurities and efficient anti-clogging.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
