[0005] The purpose of the utility model is to provide a hydrometallurgical wastewater collection device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A hydrometallurgical wastewater collection device comprises a collection tank, wherein a water inlet pipe is fixedly mounted on the top of the collection tank, a sewage pipe, a water outlet pipe, and a discharge pipe are fixedly mounted in sequence on the bottom of the collection tank, a partition plate 1, a partition plate 2, and a partition plate 3 are rotatably mounted in sequence on the inner cavity of the collection tank, and the inner cavity of the collection tank is divided into three groups of chambers by the three groups of partition plates;

[0008] The gap between partition one and partition two is set as a filter chamber, and a filter structure for preliminarily filtering wastewater is installed in the filter chamber.

When the utility model is in use, the motor drive of the anti-blocking structure realizes that the striking hammer automatically and periodically strikes the outer wall of the discharge pipe, and uses mechanical vibration to effectively peel off the attachments on the pipe wall, effectively preventing the pipe from being blocked. The pressure difference sensor of the separation pipe is linked with the main control box to accurately monitor the pressure difference changes inside and outside the separation pipe.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 、 Figure 2 A hydrometallurgical wastewater collection device includes a collection tank 1, a water inlet pipe 2 is fixedly installed on the top of the collection tank 1 through a flange, a sewage pipe 3, a water outlet pipe 4 and a discharge pipe 5 are fixedly installed on the bottom of the collection tank 1 through flanges in sequence, and a partition 1 6, a partition 2 7 and a partition 3 8 are rotatably installed in the inner cavity of the collection tank 1 through bearings in sequence, and the inner cavity of the collection tank 1 is divided into three groups of chambers by three groups of partitions;

[0025] The gap between the first partition 6 and the second partition 7 is set as a filter cavity, and a filter structure 10 for preliminary filtering of wastewater is installed in the filter cavity. The gap between the second partition 7 and the third partition 8 is set as a separation cavity, and a separation structure 11 for further filtering wastewater is installed in the separation cavity. The gap on the side of the third partition 8 away from the second partition 7 is set as a discharge cavity for discharging impurities, and the top end of the discharge pipe 5 is connected to the discharge cavity. The inner cavity of the discharge pipe 5 is fixedly installed with an anti-blocking structure 12 for preventing the discharge pipe 5 from being blocked;

[0026] Specifically, the fixed sleeve of the collection tank 1 is provided with two sets of brackets 9 for supporting the device. The inner cavities of the sewage pipe 3, the water outlet pipe 4 and the water inlet pipe 2 are all fixedly installed with throttle valves for controlling the flow. The top end of the sewage pipe 3 is connected to the filter chamber, and the top end of the water outlet pipe 4 is connected to the separation chamber.

[0027] More specifically, a main control box 13 for controlling the overall automatic operation of the device is fixedly installed on the upper surface of the collection tank 1, and a pump body 14 is fixedly connected to the bottom end of the discharge pipe 5. The pump body 14 provides suction, thereby sucking impurities in the discharge chamber and discharging them from the discharge pipe 5.

[0028] See also Figure 3 The anti-blocking structure 12 includes a fixed sleeve 121, which is fixedly sleeved on the outer wall of the discharge pipe 5. The inner cavity of the fixed sleeve 121 is rotatably connected to three groups of rotating rods 122 through a pin shaft. The bottom end of each group of rotating rods 122 is fixedly installed with a knocking hammer 123 for knocking the outer wall of the discharge pipe 5 to prevent it from being blocked, and the hammer 123 is in contact with the outer wall of the discharge pipe 5;

[0029] The top of each set of rotating rods 122 is rotatably mounted with a roller 124 through a pin to drive the rotating rod 122 to swing. The inner cavity of the roller 124 is rotatably connected to a gear ring 126 for providing rotational power to the roller 124, and the gear ring 126 is meshed with the roller 124.

[0030] Specifically, an inner nesting tube 125 is fixedly installed in the inner cavity of the fixed sleeve 121, and is used to support a gear ring 126. The gear ring 126 is rotatably installed in the inner cavity of the inner nesting tube 125. A motor 127 for providing power is installed inside the inner nesting tube 125. The output shaft of the motor 127 is fixedly connected to a gear 128. The outer wall of the gear ring 126 is provided with a sawtooth groove, and the gear 128 is meshed with the sawtooth groove.

[0031] More specifically, the rollers 124 are rotatably sleeved on the outside of the gear ring 126. The inner cavity of each group of rollers 124 is provided with an oblique tooth groove. A sawtooth block for controlling the rotation of the rollers 124 is fixedly installed on the top of the gear ring 126, and the sawtooth block is engaged with the oblique tooth groove. There are three groups of sawtooth blocks, and there are gaps between the three groups of sawtooth blocks. They are distributed at intervals and can accurately match the tooth shape of the oblique tooth groove, so as to drive the rollers 124 to produce intermittent rotation, avoid hindering the automatic reset of the rotating rod 122, and enable the rotating rod 122 to continuously swing back and forth, thereby driving the hammer 123 to periodically strike the outer wall of the discharge pipe 5, which can effectively destroy the stubborn sediment attached to the pipe wall and prevent the pipe from being blocked.

[0032] More specifically, the outer wall of the hammer 123 is made of silicone, which can convert impact energy into elastic potential energy the moment it contacts the discharge pipe 5, thereby avoiding excessive wear between components, reducing damage, and extending the service life of the device. The hammer 123 has a hollow cavity structure and is filled with quartz sand particles. This makes the hammer 123 heavier than the roller 124, forming a stable gravity pendulum. At the same time, the rotating rod 122 has a bending angle to create a lever effect.

[0033] When the roller 124 drives the rotating rod 122 to swing, the hammer 123 is controlled to move away from the discharge pipe 5. At this time, the hammer 123 stores elastic potential energy. When the roller 124 stops rotating, the hammer 123 uses its own gravitational potential energy and the lever effect of the rotating rod 122 to make the rotating rod 122 swing in the opposite direction, so that the hammer 123 hits the outer wall of the discharge pipe 5, thereby effectively removing attachments adhering to the pipe wall and avoiding blockage of the inner cavity of the discharge pipe 5. This realizes automatic cleaning of the discharge pipe 5, prevents the problem of reduced treatment efficiency due to pipe blockage, and ensures stable operation of the device.

[0034] More specifically, a sliding groove is formed on the outer wall of the inner nested tube 125 to allow the rotating rod 122 to swing, and the rotating rod 122 is located in the sliding groove.

[0035] Example 2: Please refer to Figure 2 、 Figure 4 Based on Example 1, the separation structure 11 includes a separation tube 111, the two ends of the separation tube 111 are fixedly connected to the partition plate 2 7 and the partition plate 3 8 respectively, and one end of the separation tube 111 is connected to the filter tube 101. The outer surface of the separation tube 111 is provided with multiple groups of separation holes. The inner cavity of the separation tube 111 is slidably connected to the rotating tube 112. The outer wall of the rotating tube 112 is fixedly sleeved with three groups of adsorbers 113 for adsorbing impurities inside the separation tube 111.

[0036] An adsorption tube 114 is fixedly mounted on one side of the adsorber 113 close to the separation tube 111, and one end of the adsorption tube 114 passes through the adsorber 113 and is connected to the inner cavity of the rotating tube 112. A cleaning brush 115 is fixedly mounted on the outer wall of the adsorption tube 114 to enhance the cleaning power.

[0037] Specifically, the three groups of adsorbers 113 are distributed at intervals, and the end of the rotating tube 112 away from the partition 2 7 is penetrated by the partition 3 8 and the outer wall thereof is provided with a groove. A pressure difference sensor is installed inside the separation tube 111, which can monitor the pressure difference between the inside and outside of the separation tube 111 in real time. When the suspended matter and colloidal particles in the wastewater gradually settle in the separation tube 111, resulting in an increase in the resistance of the tube wall, once the sensor detects that the pressure difference between the inside and outside reaches a preset threshold, the throttle valve of the water inlet pipe 2 is immediately closed to cut off the flow of wastewater into the channel, thereby avoiding the risk of wastewater overflow caused by pipe blockage. At the same time, the pump body 14 is started to form a negative pressure environment in the cavity of the discharge pipe 5, and with the help of the groove, the suction force is evenly transmitted to the cavity of the rotating tube 112 and the adsorber 113. Under the action of the negative pressure, the adsorber 113 adsorbs impurities in the wastewater, thereby achieving rapid removal of blockages in the separation tube 111 and simultaneously completing the secondary purification of the wastewater, thereby improving the operating efficiency and treatment effect of the overall device and ensuring the continuous and stable operation of the system under complex working conditions.

[0038] More specifically, the outer wall of the collection tank 1 is fixedly connected to the connecting frame 116 by bolts, and the inner cavity of the connecting frame 116 is fixedly installed with a motor 117, and the output end of the motor 117 is fixedly connected to the threaded shaft 118. One end of the threaded shaft 118 is passed through the rotating tube 112 and is rotatably connected to the fixing frame 119 through a bearing. The fixing frame 119 is used to fix and support the threaded shaft 118, and it is fixedly installed in the inner cavity of the partition 2 7. The threaded shaft 118 drives the rotating tube 112 to rotate while driving the rotating tube 112 to move along the threaded shaft 118, thereby improving the cleaning efficiency of the adsorber 113, expanding the range of capturing impurities, and avoiding cleaning dead corners.

[0039] See also Figure 5The filtering structure 10 includes a filter tube 101, the two ends of which are fixedly connected to the partition plate 1 6 and the partition plate 2 7 respectively. The outer surface of the filter tube 101 is provided with multiple groups of filter holes, and the diameter of the filter holes is larger than the separation hole. The outer walls of the partition plate 1 6 and the partition plate 2 7 are fixedly mounted with multiple guide blocks 102 for driving the filter tube 101 to rotate. The outer surface of the filter tube 101 is attached with a scraper 103 for scraping impurities on the surface of the filter tube 101.

[0040] Specifically, the guide block 102 is provided with a certain inclination angle. When the hydrometallurgical wastewater is injected into the filter chamber at a high speed through the water inlet pipe 2, the water flow and the inclined surface of the guide block 102 violently impact at a specific angle. According to the principle of fluid mechanics, the impact force of the water flow is decomposed into vertical pressure and horizontal thrust, the latter of which drives the guide block 102 to rotate. Since the guide block 102 is relatively connected to the filter tube 101, the filter tube 101 is caused to rotate synchronously, so that the originally static filtration process is transformed into dynamic centrifugal filtration. At the same time, during the rotation process, the outer surface of the filter tube 101 is able to contact the scraper 103 in all aspects without dead angles, so that the scraper 103 can continuously scrape off the suspended matter and sticky impurities attached to the surface of the filter tube 101, effectively avoiding clogging of the filter mesh pores and ensuring filtration efficiency. In addition, the dynamic filtration cooperates with the centrifugal force to accelerate the solid-liquid separation in the wastewater, so that the fine particle impurities settle to the bottom of the filter chamber faster.

[0041] More specifically, the scraper 103 is made of soft silicone to reduce friction and minimize damage to the filter tube 101. Mounting brackets 104 for fixing the scraper 103 are fixedly connected to both sides of the scraper 103, and the mounting brackets 104 are fixedly connected to the inner wall of the collection tank 1.

[0042] More specifically, a guide plate is provided at the bottom end of the collection tank 1 to guide the scraped impurities to flow to the sewage pipe 3, and cooperate with the throttle valve in the sewage pipe 3 to avoid leakage during daily filtration and separation of wastewater. A sensor is installed on the top of the guide plate. When the sensor senses that the impurities accumulated on the guide plate touch its top, it transmits a signal to the main control box 13, allowing it to control the flow of the water inlet pipe 2 to be cut off before the sewage pipe 3 can be opened for flow.

[0043] The working principle of this utility model is:

[0044] First, after the wastewater enters the collection tank 1 through the water inlet pipe 2, it flows into the filter chamber formed by the partition 1 6 and the partition 2 7. The wastewater impacts the guide block 102 and drives the filter tube 101 to rotate, upgrading the static filtration to dynamic centrifugal filtration, accelerating the solid-liquid separation and completing the preliminary filtration. At the same time, the scraper 103 continuously scrapes the impurities on the surface of the filter tube 101. The scraped impurities accumulate on the guide plate at the bottom of the collection tank 1. When the sensor on the top of the guide plate detects that the impurities have accumulated to a certain extent, it will feed back a signal to the main control box 13, which controls the flow of the water inlet pipe 2 to be cut off, and then opens the sewage pipe 3 to discharge the impurities.

[0045] The wastewater after preliminary filtration enters the separation chamber formed by the partition plate 2 7 and the partition plate 3 8. The separation holes on the separation tube 111 can be used for secondary filtration, and the separated wastewater is discharged from the outlet pipe 4. When the pressure difference sensor in the separation tube 111 detects that the internal and external pressure difference reaches a preset threshold, indicating that internal impurities accumulate and the pipe wall resistance increases, the main control box 13 immediately closes the throttle valve of the water inlet pipe 2 and starts the pump body 14 at the same time to form a negative pressure in the discharge pipe 5. The negative pressure is transmitted to the adsorber 113 through the slots of the rotating tube 112. The adsorption tube 114 cooperates with the cleaning brush 115 to adsorb and remove the blockage in the separation tube 111, thereby achieving secondary purification of the wastewater. At the same time, the motor 117 drives the threaded shaft 118 to make the rotating tube 112 move axially while rotating, thereby expanding the cleaning range of the adsorber 113 and improving the treatment effect.

[0046] Finally, the impurities washed out by the adsorber 113 are transported to the discharge chamber through the slots and discharged through the discharge pipe 5. At the same time, the anti-blocking structure 12 is started to realize automatic clearing through mechanical transmission. The motor 127 drives the gear 128 to rotate, driving the gear ring 126 to rotate. The serrated block at the top of the gear ring 126 engages with the oblique tooth groove in the inner cavity of the roller 124, causing the roller 124 to rotate intermittently. The roller 124 drives the rotating rod 122 to swing. When the roller 124 stops rotating, the hammer 123 swings in the opposite direction by virtue of its own gravity and the leverage effect of the rotating rod 122, periodically hitting the outer wall of the discharge pipe 5, shaking off the attachments on the pipe wall, and preventing the pipeline from being blocked.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
