Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device for gold production. Background Technology

[0002] Cyanide, as an indispensable chemical raw material in modern industry, is used in metallurgy, mining, and petroleum. It has been widely used in fields such as coal mining. However, the cyanide-containing wastewater generated during its industrial production is highly toxic and has a complex composition, posing a serious threat to the ecological environment and biosafety.

[0003] Adsorbents, as a conventional method of wastewater treatment, are widely used. Manufacturing processes are lengthy, and wastewater production is continuous. Therefore, the drawback of temporary wastewater treatment methods in manufacturing is the large storage area and high space occupancy. While a flow channel structure can reduce the footprint, the adsorbent's movement within the channel is easily affected by the fluid flow. If the adsorbent is confined to a specific area, a certain length of pipe needs to be installed to accommodate it and increase mass transfer, thus increasing the pipe length. Utility Model Content

[0004] This invention provides a wastewater treatment device for gold production that concentrates particulate matter, overcomes the influence of fluids, and creates a longer flow channel inside, enabling full mass transfer and easy replacement.

[0005] This utility model provides the following technical solution: it includes a filter housing, the interior of which is filled with a filler partition; The packing partition consists of no fewer than three parallel inclined transition plates. Each parallel inclined transition plate includes a coincident plate and a separation plate that are parallel to each other but located on different planes. The coincident plate and the separation plate are connected by an inclined plate. The multiple coincident plates are distributed at equal angles around the axis of the filter housing. Adjacent coincident plates are fixedly connected to each other. A central region is formed among multiple separating plates, and a connected region is formed between two adjacent separating plates, with the connected region connected to the central region.

[0006] The filter housing consists of a sieve cylinder and two sieve covers that seal both ends of the sieve cylinder. The sieve covers are fixedly connected to the sieve cylinder or are detachably connected to it.

[0007] The common plane formed by the multiple overlapping plates is fixedly connected to one of the sieve covers.

[0008] The overlapping plate and the inclined plate, as well as the inclined plate and the separating plate, each have an arc-shaped transition surface.

[0009] The number of parallel inclined transition plates is six.

[0010] In a clockwise direction, the extension line of the rear separating plate intersects the plane of the front separating plate.

[0011] The beneficial effects of this utility model are: This technical solution can employ forward, reverse, and lateral packing methods, and uses multiple parallel inclined transition plates to guide and form a composite motion, increasing the diversity of fluid motion and thus increasing the fluid's travel distance within the filter housing. With the flow channel length remaining constant, this technical solution has a high fluid travel distance, resulting in higher mass transfer efficiency and a wide range of applications.

[0012] The specific advantages are as follows: Advantage A: If the filter housing is filled in the pipeline, the overlapping plate is located in the windward direction. The particles are filled inside the filter housing and separated by parallel inclined transition plates. After the fluid enters the overlapping plate, it first contacts the particles inside the overlapping plate for mass transfer and is guided to the interior of the separation plate by the inclined plates. A portion of the fluid will directly pass through the separation plate along the axial direction of the filter housing and be discharged through the filter housing. When the particles on the end face of the filter housing discharged through the separation plate become blocked, the fluid will be squeezed into the central area through the separation plate under pressure and discharged through the sieve surface of the filter housing corresponding to the central area.

[0013] Advantage B: If an open flow channel is used, the filter housing is placed vertically on the bottom of the flow channel, with the arc surface of the filter housing facing the direction of water flow. The fluid enters the central area through the connecting zone and is guided by multiple separating plates to form a complex motion, increasing the diversity of fluid motion and thus increasing the fluid's travel distance within the filter housing. With the flow channel length remaining constant, this technical solution has a high fluid travel distance, resulting in higher mass transfer efficiency.

[0014] Advantage C: If the central area faces the direction of water flow, part of the water flow will move in the direction of advantage A of the packing material, and another part of the water flow will impact the center of the central area. Since there is no cross surface for fluid flow at the center of the central area, the fluid located at the center of the central area will disperse to the surrounding areas and pass through the gap between the two adjacent inclined plates into the overlapping plate.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-5 The present invention provides the following technical solution: including a filter housing 1, the interior of which is filled with a filler partition; The packing partition consists of no less than three parallel inclined transition plates 2. The parallel inclined transition plates 2 include overlapping plates 21 and separating plates 23 that are parallel to each other but located on different planes. The overlapping plates 21 and the separating plates 23 are connected by an inclined plate 22. The multiple overlapping plates 21 are distributed at equal angles around the axis of the filter housing 1. Adjacent overlapping plates 21 are fixedly connected to each other. Multiple separate plates 23 form a central region 4, and two adjacent separate plates 23 form a connected region 3, which is connected to the central region 4.

[0018] In this embodiment: the filter housing 1 is made of metal or polymer plastic, the filter housing 1 has multiple pores, the filter housing 1 has a circular inner cavity, and the packing partition is located inside the filter housing 1.

[0019] The specific shape of the packing partition can be understood as being composed of multiple parallel inclined transition plates 2 rotating together. In this embodiment, it is composed of six parallel inclined transition plates 2. The six overlapping plates 21 form a snowflake body shape. The inclined plates 22 and the separation plates 23 form a shape similar to an impeller. The space between the inclined plates 22 and the separation plates 23 is the central area 4. The two adjacent separation plates 23 form a connecting area 3.

[0020] For the advantages of the filler material A, please refer to 2. If the filter housing 1 is filled in the pipeline and the overlapping plate 21 is located in the windward direction, the particles are filled inside the filter housing 1 and separated by the parallel inclined transition plate 2. After the fluid enters the overlapping plate 21, it first contacts the particles inside the overlapping plate 21 for mass transfer and is guided to the interior of the separation plate 23 by the inclined plate 22. A portion of the fluid will directly pass through the separation plate 23 along the axial direction of the filter housing 1 and be discharged through the filter housing 1. When the particles on the end face of the filter housing 1 discharged through the separation plate 23 become blocked, the fluid will be squeezed into the central area 4 through the separation plate 23 under pressure and discharged through the sieve surface of the filter housing 1 corresponding to the central area 4.

[0021] For packing advantage B, please refer to [link / reference]. Figure 5 If an open flow channel is used, the filter housing 1 is placed vertically on the bottom surface of the flow channel, with the arc surface of the filter housing 1 facing the direction of water flow. The fluid enters the central zone 4 through the connecting zone 3 and is guided by multiple separating plates 23 to form a complex motion, increasing the diversity of fluid motion and thus increasing the fluid's travel distance within the filter housing 1. With the flow channel length remaining constant, this technical solution has a high fluid travel distance, resulting in higher mass transfer efficiency.

[0022] For advantages of filler C, please refer to [link / reference]. Figure 4 If the central area 4 is facing the direction of water flow, part of the water flow will move in the direction of the packing advantage A, and another part of the water flow will impact the center of the central area 4. Since there is no fluid flow crossing surface at the center of the central area 4, the fluid located at the center of the central area 4 will disperse to the surroundings and pass through the gap between the two adjacent inclined plates 22 into the overlapping plate 21.

[0023] The filter housing 1 consists of a screen cylinder and two screen covers that seal both ends of the screen cylinder. The screen covers are fixedly connected to the screen cylinder or can be detachably connected.

[0024] If the adsorbent material is disposable and cannot be reused, the sieve cover and sieve cylinder are fixedly connected. If the material can be desorbed and reused, the sieve cover and sieve cylinder are detachably connected, and the detachment methods include, but are not limited to, snap-fit ​​connections, threaded connections, and adhesive bonding.

[0025] The common plane formed by multiple overlapping plates 21 is fixedly connected to one of the sieve covers. The overlapping plates 21 are fixedly connected to the sieve cover, so that the periphery of the parallel inclined transition plate 2 does not contact the circumferential surface of the filter shell 1, reducing the number of corner points. Therefore, corner points are prone to causing gaps to form between the spherical adsorbent and the corner.

[0026] There are arc-shaped transition surfaces between the overlapping plate 21 and the inclined plate 22, and between the inclined plate 22 and the separating plate 23. The arc-shaped transition surfaces can reduce the kinetic energy loss of the fluid when it moves through the overlapping plate 21, the inclined plate 22, and the separating plate 23.

[0027] In a clockwise direction, the extension line of the rear separation plate 23 intersects the plane of the front separation plate 23, the purpose of which is to guide the water flow in order to achieve the packing advantage B.
