Abstract
Description
Technical Field
[0001] This utility model relates to the field of montmorillonite production technology, specifically to a montmorillonite production wastewater sedimentation and recovery device. Background Technology
[0002] Montmorillonite is a layered mineral composed of extremely fine-grained hydrous aluminosilicates. It is a major component of bentonite, which is formed by the alteration of igneous rocks such as volcanic conglomerate in an alkaline environment. During the washing, flotation, and chemical treatment processes of raw montmorillonite ore, wastewater containing suspended solids and a small amount of chemical residues is generated. This wastewater needs to be treated, which requires the use of wastewater sedimentation and recovery devices.
[0003] To improve sedimentation efficiency and effectiveness, existing wastewater sedimentation and recovery devices are usually bulky, which not only has a high capital investment cost, but also requires a certain amount of processing space. This makes it inconvenient to carry out high-efficiency sedimentation in a small space, and it is also inconvenient to remove residual sediments on the sedimentation surface after sedimentation.
[0004] In view of this, we have studied and improved the existing structure and its shortcomings, and proposed a sedimentation and recovery device for montmorillonite production wastewater. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this utility model is to provide a sedimentation and recovery device for montmorillonite production wastewater.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a montmorillonite production wastewater sedimentation and recovery device, comprising a wastewater sedimentation tank, a first inclined plate, and a sludge scraping assembly. A central guide rod is fixed to the inner side of the middle part of the wastewater sedimentation tank by a fixing rod, and the first inclined plate is fixed at equal intervals on the inner wall of the wastewater sedimentation tank. A second inclined plate is fixed at equal intervals on the outer wall of the central guide rod. A sludge scraping assembly is installed at the bottom of the central guide rod, and the sludge scraping assembly includes a rotary motor, a rotary shaft, a connecting rod, a connecting plate, a first sludge scraper, and a second sludge scraper. A rotary shaft is provided on the lower side of the rotary motor, and a connecting rod is connected to one side of the rotary shaft. A connecting plate is fixed to one side of the connecting rod, and the first sludge scraper and the second sludge scraper are respectively connected to the bottom and the upper side of the connecting plate. The upper side of the second sludge scraper is connected to another connecting plate.
[0007] Furthermore, the vertical center line of the central guide rod coincides with the vertical center line of the wastewater sedimentation tank, and a guide vane is fixed on the lower outer side of the central guide rod.
[0008] Furthermore, the first inclined plate has a funnel-shaped structure, and the second inclined plate has an inverted funnel-shaped structure, and the cross-sections of the first and second inclined plates are both inclined surfaces.
[0009] Furthermore, an inlet cylinder is connected to the upper side of the wastewater sedimentation tank, and a guide spiral blade is fixed to the inner wall of the inlet cylinder.
[0010] Furthermore, the wastewater sedimentation tank is connected to two outlet pipes, one above the other, and a filter screen is fixed inside one side of the outlet pipe. The outlet pipe is located below the first inclined plate, and the curvature of the inner side of the filter screen is the same as the curvature of the inner wall of the wastewater sedimentation tank.
[0011] Furthermore, the sludge scraping assembly also includes anti-clogging scrapers. One end of each of the two first sludge scrapers on the lower side is fixed with an anti-clogging scraper, and the first sludge scraper and the second sludge scraper are respectively attached to the upper side of the first inclined plate and the second inclined plate.
[0012] Furthermore, a sedimentation tank is provided on the lower side of the wastewater sedimentation tank, and a sewage pipe is connected to the lower middle part of the sedimentation tank, and a sewage valve is installed on the lower side of the sewage pipe.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The first and second inclined plates, arranged in layers, facilitate the formation of a multi-layer sedimentation structure, extending the water flow path and increasing the separation time between particles and water, thereby improving the sedimentation speed and effect, and helping to reduce sedimentation time and device volume. The inlet cylinder facilitates the inflow of wastewater into the sedimentation tank, and the guide spiral blades on the inner wall of the inlet cylinder facilitate the flow of wastewater into the sedimentation tank, making the wastewater enter in a swirling manner. Through the swirling effect, the particulate matter in the wastewater quickly gathers to the periphery under the action of centrifugal force, and then the first inclined plate on the periphery increases the sedimentation area and sedimentation efficiency. The cross-sections of the first and second inclined plates are both inclined, which allows the fine particles on their surfaces to slide down more quickly.
[0015] 2. A sludge scraping assembly is provided. Multiple first and second sludge scrapers are attached to the upper sides of the first and second inclined plates and connected by a connecting plate. A rotary motor and a rotary shaft facilitate the rotation of the connecting rod and the connecting plate, which in turn drives the rotation of the first and second sludge scrapers. This allows the first and second sludge scrapers to periodically scrape away residual sediment from the surfaces of the first and second inclined plates. In addition, the first sludge scrapers can drive the rotation of the anti-clogging scraper, so that when the anti-clogging scraper rotates to the inner side of the filter screen, it can clean the filter screen to prevent clogging.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 2 As shown, this embodiment of a montmorillonite production wastewater sedimentation and recovery device includes a wastewater sedimentation tank 1, a first inclined plate 5, and a sludge scraping assembly 7. A central guide rod 3 is fixed to the inner side of the middle part of the wastewater sedimentation tank 1 by a fixing rod 2, and the first inclined plate 5 is fixed at equal intervals on the inner wall of the wastewater sedimentation tank 1. The second inclined plate 6 is fixed at equal intervals on the outer wall of the central guide rod 3. The vertical center line of the central guide rod 3 coincides with the vertical center line of the wastewater sedimentation tank 1, and a guide vane 4 is fixed to the lower outer side of the central guide rod 3. The first inclined plate 5 has a funnel-shaped structure, and the second inclined plate 6 has an inverted funnel-shaped structure. The cross-sections of the first inclined plate 5 and the second inclined plate 6 are both inclined surfaces. An inlet cylinder 8 is connected to the upper side of the wastewater sedimentation tank 1, and a guide spiral blade 9 is fixed to the inner wall of the inlet cylinder 8.
[0022] Specifically, the layered arrangement of the first inclined plate 5 and the second inclined plate 6 facilitates the formation of a multi-layer sedimentation structure, extending the water flow path and increasing the separation time between particles and water, thereby improving the sedimentation speed and effect, and helping to reduce sedimentation time and device volume. The inlet cylinder 8 facilitates the inlet of wastewater sedimentation tank 1, and the guide spiral blades 9 on the inner wall of the inlet cylinder 8 facilitate the flow of wastewater into the wastewater sedimentation tank 1, making the wastewater enter in a swirling manner. Through the swirling effect, the particulate matter in the wastewater quickly gathers to the periphery under the action of centrifugal force, and then the first inclined plate 5 on the periphery increases the sedimentation area and sedimentation efficiency. The cross-sections of the first inclined plate 5 and the second inclined plate 6 are both inclined surfaces, which allows the fine particles on their surfaces to slide down more quickly.
[0023] like Figure 2 and Figure 3As shown, the wastewater sedimentation tank 1 has two outlet pipes 10 connected to its side, and a filter screen 11 is fixed inside one side of the outlet pipe 10. The outlet pipe 10 is located below the first inclined plate 5. The inner side curvature of the filter screen 11 is the same as the inner wall curvature of the wastewater sedimentation tank 1. A sedimentation tank 12 is provided on the lower side of the wastewater sedimentation tank 1. A sewage pipe 13 is connected to the lower side of the middle part of the sedimentation tank 12. A sewage valve 14 is installed on the lower side of the sewage pipe 13.
[0024] Specifically, the two water outlet pipes 10 at different heights allow for selection of water outlet channels as needed. The water outlet pipes 10 are located below the side of the first inclined plate 5, which can reduce the impurity content at the water outlet. The filter screen 11 facilitates the filtration of impurities at the water outlet, further removing impurities and improving the water quality of the outlet, so as to facilitate the recycling of wastewater. The sedimentation tank 12 is used to collect the sedimented impurities, and the sewage pipe 13 facilitates the centralized discharge of impurities.
[0025] like Figure 1 As shown, a scraping assembly 7 is installed at the bottom of the central guide rod 3. The scraping assembly 7 includes a rotary motor 701, a rotary shaft 702, a connecting rod 703, a connecting plate 704, a first scraper 705, and a second scraper 706. The rotary shaft 702 is located below the rotary motor 701, and a connecting rod 703 is connected to one side of the rotary shaft 702. A connecting plate 704 is fixed to one side of the connecting rod 703, and the first scraper 705 and the second scraper 706 are respectively connected to the bottom and top of the connecting plate 704. Two scraper blades 706 are provided, and the upper side of the second scraper blade 706 is connected to another connecting plate 704; the scraper assembly 7 also includes an anti-clogging scraper 707, and one end of the two lower first scraper blades 705 is fixed with the anti-clogging scraper 707, and the first scraper blades 705 and the second scraper blades 706 are respectively attached to the upper side of the first inclined plate 5 and the second inclined plate 6; multiple first scraper blades 705 and second scraper blades 706 attached to the upper side of the first inclined plate 5 and the second inclined plate 6 are connected by the connecting plate 704;
[0026] Specifically, the rotating motor 701 and rotating shaft 702 facilitate the rotation of the connecting rod 703 and connecting plate 704, which in turn drives the rotation of the first scraper 705 and the second scraper 706. This allows the first scraper 705 and the second scraper 706 to scrape away residual sediment on the surface of the first inclined plate 5 and the second inclined plate 6 during periodic cleaning. At the same time, the first scraper 705 can drive the rotation of the anti-clogging scraper 707, so that when the anti-clogging scraper 707 rotates to the inner side of the filter screen 11, it can clean the filter screen 11 to prevent clogging.
[0027] Working principle: Wastewater from the washing of montmorillonite ore is fed into the inlet cylinder 8. The guide spiral blades 9 on the inner wall of the inlet cylinder 8 guide the wastewater entering the wastewater sedimentation tank 1, causing the wastewater to enter in a swirling flow. Through the swirling effect, the particulate matter in the wastewater is rapidly aggregated to the periphery under the action of centrifugal force. The first inclined plate 5 on the periphery increases the sedimentation area and sedimentation efficiency. Then, the guide blades 4 below the central guide rod 3 play a secondary guiding role. At this time, the first inclined plate 5 and the second inclined plate 6 set in layers facilitate the formation of a multi-layer sedimentation structure, which prolongs the water flow path and increases the separation time between particles and water, thereby improving the sedimentation speed and effect. In addition, the cross-sections of the first inclined plate 5 and the second inclined plate 6 are both inclined, which allows the fine particles on their surfaces to slide down more quickly. Finally, the sedimentation tank 12 below can collect the sedimented impurities, and the impurities can also be centrally discharged through the drain pipe 13.
[0028] Drainage can be achieved through two outlet pipes 10 at different heights, located below the side of the first inclined plate 5. This reduces the impurity content at the outlet. The filter screen 11 filters impurities at the outlet, further removing impurities and improving the quality of the effluent, thus enabling wastewater recycling. During regular cleaning, the rotating motor 701 and rotating shaft 702 drive the connecting rod 703 and connecting plate 704 to rotate. Multiple first scraper blades 705 attached to the upper sides of the first inclined plate 5 and the second inclined plate 6... The second scraper 706 is connected to the connecting plate 704, which in turn drives the rotation of the first scraper 705 and the second scraper 706. This allows the first scraper 705 and the second scraper 706 to scrape away residual sediment on the surface of the first inclined plate 5 and the second inclined plate 6 during periodic cleaning. The first scraper 705 can also drive the rotation of the anti-clogging scraper 707, so that when the anti-clogging scraper 707 rotates to the inner side of the filter screen 11, it can clean the filter screen 11 to prevent clogging. This completes the usage process of the montmorillonite production wastewater sedimentation and recovery device.
