A sedimentation-resistant temporary wastewater storage tank for zinc smelting wastewater

Abstract

This utility model provides an anti-settling wastewater storage tank for zinc smelting wastewater, relating to the field of wastewater treatment technology. The anti-settling component includes a support bracket welded to the outside of the wastewater storage tank. A lifting hydraulic rod is installed on the upper side of the support bracket, and a motor support plate is set in the middle of the lifting hydraulic rod. A rotary motor is installed on the inner side of the motor support plate. Activating the lifting hydraulic rod can move the motor support plate up and down, thereby adjusting the height of the rotary motor. This allows the connected stirring blades to fully stir the wastewater at different depths, preventing impurities from settling. The stirring depth can be flexibly adjusted according to changes in the wastewater level. When the rotary motor is activated, the stirring blades rotate via the motor shaft, agitating the wastewater and disturbing the impurities deposited in the water. Impurities deposited at the bottom of the wastewater storage tank are scraped up by the bottom shovel plate and carried to the top as the stirring blades rotate.

Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and in particular to a sedimentation-resistant wastewater storage tank for zinc smelting waste liquid. Background Technology

[0002] Anti-sedimentation wastewater storage tanks for zinc smelting wastewater are temporary storage facilities designed for smelting wastewater containing zinc, heavy metals, and suspended solids. They inhibit the settling and agglomeration of solid particles in the wastewater through built-in stirring devices, flow guiding structures, or air flotation systems. They also have corrosion resistance and leak-proof properties, and can temporarily store wastewater while maintaining its homogeneity, ensuring stable feeding for subsequent wastewater treatment processes and avoiding pipeline blockage and reduced treatment efficiency.

[0003] During the discharge of zinc smelting wastewater, which contains a large amount of heavy metal particles and suspended solids, temporary storage is usually required. However, traditional wastewater storage tanks often use simple static storage structures. In subsequent use, solid particles tend to accumulate large amounts of sediment at the bottom of the tank, making subsequent cleaning difficult. Even with stirring structures, most can only perform fixed stirring, which has limited effect on cleaning sediment at the bottom of the tank. Furthermore, the clumps of sediment in the wastewater are difficult to stir completely, resulting in low stirring efficiency.

[0004] Therefore, we provide a sedimentation-resistant temporary wastewater storage tank for zinc smelting wastewater to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sedimentation-resistant wastewater storage tank for zinc smelting wastewater includes a wastewater storage tank body. A ring frame is welded to the top inner side of the wastewater storage tank body. A filter screen frame is installed on the upper side of the ring frame. An anti-settling component is provided on the upper side of the wastewater storage tank body. The anti-settling component includes a support bracket welded to the outer side of the wastewater storage tank body. A lifting hydraulic rod is installed on the upper side of the support bracket. A motor support plate is located in the middle of the lifting hydraulic rod. A rotary motor is installed inside the motor support plate. An air-flushing component is provided on the outer side of the wastewater storage tank body.

[0006] As a further description of the above technical solution: The sewage storage tank has a circular conical structure, is made of cement, and has a glaze coating on its surface.

[0007] As a further description of the above technical solution: The filter screen frame and the ring frame are connected by a slot, and the filter screen frame has a honeycomb disc structure.

[0008] As a further description of the above technical solution: The lifting hydraulic rods are symmetrically arranged on the left and right sides, and the lifting hydraulic rods drive a rotary motor through a motor support plate to form a lifting structure.

[0009] As a further description of the above technical solution: A side limiting rod is welded to the outside of the motor support plate. The side limiting rod is connected to the support bracket by a slot. The side limiting rod and the support bracket are arranged symmetrically in two sets on the left and right sides.

[0010] As a further description of the above technical solution: The lower shaft of the rotary motor is connected to a motor shaft. An agitator blade is welded to the outside of the motor shaft. A shovel plate is welded to the end of the agitator blade. The shovel plate is inclined at a 60-degree angle, and the end of the shovel plate is in close contact with the bottom of the sewage storage tank.

[0011] As a further description of the above technical solution: The air-flushing assembly includes pulse-type air pumps all located on the outside of the sewage storage tank. Fine jet panels are installed on the inside of the sewage storage tank. An air supply pipe is connected to the outer pipe of the pulse-type air pump, and an air supply tank is connected to the outer pipe of the air supply pipe. The pulse-type air pumps are arranged in four groups at equal distances. The pulse-type air pumps are connected to the fine jet panels by pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses an anti-sinking component to activate the lifting hydraulic rod, which moves the motor support plate up and down, thereby adjusting the height of the rotating motor. This allows the connected stirring blades to fully stir the sewage at different depths, preventing impurities from settling. At the same time, the stirring depth can be flexibly adjusted according to changes in the waste liquid level. When the rotating motor is activated, the stirring blades are rotated through the motor shaft, stirring the sewage and disturbing the impurities deposited in the water. The impurities deposited at the bottom of the sewage storage tank are scraped up by the bottom shovel plate and carried to the top as the stirring blades rotate, re-entering the sewage flow cycle.

[0013] 2. This utility model uses an air-flushing component to activate a pulse-type air pump, which sprays gas from the air supply tank through the air supply pipe and the pulse-type air pump from the fine jet panel. This disperses impurities in the wastewater, preventing them from accumulating in the water flow and affecting the anti-sedimentation effect, thus improving subsequent treatment efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 As shown, this utility model provides a technical solution: a sewage temporary storage tank for zinc smelting wastewater that prevents sedimentation, comprising a sewage temporary storage tank body 1, a ring frame 2 welded to the top inner side of the sewage temporary storage tank body 1, a filter screen frame 3 installed on the upper side of the ring frame 2, an anti-settling component 4 provided on the upper side of the sewage temporary storage tank body 1, the anti-settling component 4 including a support bracket 401 welded to the outer side of the sewage temporary storage tank body 1, a lifting hydraulic rod 402 installed on the upper side of the support bracket 401, a motor support plate 403 provided in the middle of the lifting hydraulic rod 402, a rotary motor 405 installed on the inner side of the motor support plate 403, and an air flushing component 5 provided on the outer side of the sewage temporary storage tank body 1.

[0018] Furthermore, the wastewater storage tank 1 has a circular conical structure. The wastewater storage tank 1 is made of cement and has a glaze coating on its surface. When it is needed, the conical structure of the wastewater storage tank 1 is more conducive to the concentration of impurities in the wastewater than the planar structure, thereby improving the anti-deposition effect by reducing the sedimentation area of ​​impurities in the wastewater.

[0019] Furthermore, the filter screen frame 3 and the ring frame 2 are connected by a slot. The filter screen frame 3 has a honeycomb disc structure. When needed, the honeycomb disc filter screen frame 3 can effectively intercept large particulate impurities in the waste liquid, thereby avoiding the situation where large volume impurities are deposited at the bottom of the tank. Large volume impurities are prone to accumulate at the bottom of the sewage temporary storage tank 1, increasing the difficulty of preventing sedimentation.

[0020] Furthermore, the lifting hydraulic rod 402 is symmetrically arranged on the left and right sides. The lifting hydraulic rod 402 drives the rotary motor 405 through the motor support plate 403 to form a lifting structure. When needed, by starting the lifting hydraulic rod 402, the motor support plate 403 can be moved up and down, thereby adjusting the height position of the rotary motor 405, so that the connected stirring fan blades 407 can fully stir the sewage at different depths, prevent impurities from settling, and flexibly adjust the stirring depth according to the changes in the liquid level of the waste liquid.

[0021] Furthermore, a side limiting rod 404 is welded to the outer side of the motor support plate 403. The side limiting rod 404 and the support bracket 401 are connected by a slot. The side limiting rod 404 and the support bracket 401 are symmetrically arranged in two sets on the left and right sides. When needed, as the lifting hydraulic rod 402 extends and retracts, the side limiting rod 404 slides in the slot of the support bracket 401 to ensure that the motor support plate 403 remains stable during the lifting process, and to avoid unstable operation of the rotary motor 405 due to shaking, which would affect the stirring effect.

[0022] Furthermore, a motor shaft 406 is connected to the lower shaft of the rotary motor 405. An agitator blade 407 is welded to the outside of the motor shaft 406. A shovel plate 408 is welded to the end of the agitator blade 407. The shovel plate 408 is inclined at a 60-degree angle, and the end of the shovel plate 408 is in close contact with the bottom of the sewage storage tank 1. When needed, the rotary motor 405 is started, and the agitator blade 407 is rotated through the motor shaft 406 to agitate the sewage and disturb the impurities deposited in the water. The impurities deposited at the bottom of the sewage storage tank 1 are scraped up by the shovel plate 408 and carried to the top as the agitator blade 407 rotates, re-entering the sewage flow cycle.

[0023] Furthermore, the air-flushing assembly 5 includes pulse-type air pumps 501 all located on the outside of the wastewater storage tank 1. Fine jet spray panels 502 are installed on the inside of the wastewater storage tank 1. An air supply pipe 503 is connected to the outer pipe of each pulse-type air pump 501, and an air supply tank 504 is connected to the outer pipe of the air supply pipe 503. The pulse-type air pumps 501 are arranged in four groups at equal intervals. Pipes connect the pulse-type air pumps 501 to the fine jet spray panels 502. When needed, the pulse-type air pumps 501 are activated, and the gas in the air supply tank 504 is ejected from the fine jet spray panels 502 through the air supply pipe 503 in conjunction with the pulse-type air pumps 501. This disperses impurities in the wastewater, preventing them from accumulating in the water flow and affecting the anti-sedimentation effect, thus improving subsequent treatment efficiency.

[0024] Working principle: When needed, the wastewater storage tank 1 is first placed in the desired location. Then, zinc smelting waste liquid is injected into the wastewater storage tank 1. During this process, the filter screen 3 on the ring frame 2 performs preliminary filtration of impurities, thereby filtering out large-volume impurities and preventing them from settling to the bottom due to their large weight. Subsequently, the zinc smelting waste liquid passes through the filter screen 3 and enters the interior of the wastewater storage tank 1. At this time, the rotary motor 405 in the middle of the motor support plate 403 periodically drives the motor shaft 406 to rotate. During the rotation of the motor shaft 406, the stirring fan blades 40... 7. The wastewater is stirred, while the bottom scraper plate 408 scrapes the bottom of the wastewater storage tank 1. During the stirring process, the lifting hydraulic rod 402 on the support bracket 401 drives the rotary motor 405 to move up and down through the motor support plate 403, thereby achieving full-height stirring. During the stirring process, the pulse air pump 501 draws gas from the air supply tank 504 through the air supply pipe 503 and sprays it into the water through the fine jet panel 502 to disperse the impurities condensed in the water. This completes the use of a sedimentation-resistant wastewater storage tank for zinc smelting wastewater.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
