Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a mud removal device for a treatment pool for chemical sewage. Background Art

[0002] In the process of chemical wastewater treatment, the treatment tank, as one of the core equipment, is responsible for removing pollutants such as suspended matter, organic matter and some heavy metals in the wastewater.

[0003] However, as the sewage treatment process continues, a large amount of silt and sediment inevitably accumulates inside the treatment tank. This silt not only occupies the effective volume of the treatment tank, reducing the efficiency of sewage treatment, but may also release harmful gases due to long-term accumulation, posing a potential threat to the environment and the health of operators.

[0004] Existing chemical wastewater treatment systems rely heavily on manual cleaning or simple mechanical sludge removal equipment. These methods suffer from low treatment efficiency, high labor intensity, and incomplete cleaning. Manual cleaning is not only time-consuming and labor-intensive, but also difficult to ensure timely and comprehensive cleaning. Simple mechanical sludge removal equipment, however, often suffers from poor design or insufficient power, failing to effectively remove sludge from the bottom of the treatment tank. This leads to repeated sludge deposition within the tank, further deteriorating water quality and compromising overall treatment effectiveness.

[0005] In view of the above problems, a desludging device for a treatment pool for chemical wastewater is now designed. Utility Model Content

[0006] The embodiment of the present application provides a desludging device for a treatment pool for chemical wastewater to solve the problems in the related art that the existing chemical wastewater treatment systems mostly rely on manual cleaning or simple mechanical desludging equipment, resulting in low treatment efficiency, high labor intensity, and incomplete cleaning.

[0029] The embodiment of the present application provides a desludging device for a treatment pool for chemical wastewater, which can solve the problems in the related art that the existing chemical wastewater treatment systems mostly rely on manual cleaning or simple mechanical desludging equipment, and have low treatment efficiency, high labor intensity, and incomplete cleaning.

[0031] Your description fully illustrates the workflow and advantages of the chemical wastewater treatment tank desludging device of the present invention. The following is a summary and supplement to your description to better understand and demonstrate the working principle and beneficial effects of the device:

[0032] During normal operation of the treatment tank 1, suspended solids and particulate matter in the sewage gradually settle to the bottom of the tank under the action of gravity, forming a sludge layer. The sludge automatically flows into the collection bin 2 through the communication port between the bottom of the treatment tank 1 and the collection bin 2.

[0033] When the sludge in the collection bin 2 accumulates to a certain amount, the driver 4 is activated, transmitting power to the screw 3 via the reducer, driving the screw 3 to rotate inside the collection bin 2. The rotation of the screw 3 generates thrust toward the delivery pipe 5, gradually pushing the sludge in the collection bin 2 to the delivery pipe 5. In this process, the sludge is effectively compressed and propelled forward, and is eventually discharged from the treatment system through the delivery pipe 5, achieving automated sludge treatment.

[0034] While the sludge is being pushed and discharged, the agitator 6 is started, which drives the scraper 7 to rotate to scrape the sludge at the bottom of the treatment tank 1. The scraped sludge enters the collection bin 2 again through the connecting port between the treatment tank 1 and the collection bin 2.

[0035] Through the automatic operation of the collecting bin 2, the screw rod 3, the driving part 4, the conveying pipe 5, the agitator 6 and the scraper 7, the automatic collection, pushing and discharge of the sludge, the stirring of the sewage and the scraping of the bottom sludge are realized, which greatly reduces the labor intensity of manual cleaning and improves work efficiency.

[0036] The combined use of the agitator 6 and the scraper 7 not only promotes the mixing of sewage and microorganisms or chemicals, thereby improving the efficiency and quality of sewage treatment, but also effectively prevents the deposition of sludge at the bottom of the treatment tank 1, thereby avoiding the negative impact of sludge on the sewage treatment effect.

[0037] The design of the collecting chamber 2 being embedded in the bottom of the treatment tank 1 makes the entire desilting device compact in structure and occupies a small area, which is very suitable for chemical wastewater treatment systems with limited space.

[0038] The design that the delivery pipe 5 is connected to the bottom of the collection bin 2 is convenient for cleaning and maintenance. When the delivery pipe 5 or the collection bin 2 needs to be cleaned, it can be easily disassembled and cleaned, reducing the failure rate caused by silt blockage.

[0039] Specifically, such as Figure 2 As shown, the collecting bin 2 in this embodiment is semicircular, the top of the collecting bin 2 is open, and a strip-shaped through hole communicating with the collecting bin 2 is provided on the top of the treatment pool 1 .

[0040] The top of the collecting bin 2 is open, so that the sludge in the treatment tank 1 can flow smoothly into the collecting bin 2 by gravity. At the same time, the design of the opening also facilitates subsequent cleaning and maintenance work.

[0041] The treatment tank 1 is provided with strip-shaped through holes communicating with the collection bin 2. These strip-shaped through holes serve as channels for the sludge to enter the collection bin 2, ensuring that the sludge can flow into the collection bin 2 quickly and avoiding the formation of an excessively thick sludge layer at the bottom of the treatment tank 1.

[0042] In one embodiment, Figure 4 As shown, the driving member 4 includes a driving motor and a reducer. The reducer is arranged at the end of the collecting bin 2, and the driving motor is arranged on the reducer. The output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to one end of the screw rod 3; a bearing seat is provided at the other end of the collecting bin 2, and the other end of the screw rod 3 rotates with the bearing seat.

[0043] The output shaft of the drive motor is tightly connected to the input shaft of the reducer, ensuring that the power generated by the motor is transmitted to the reducer without loss. The reducer converts the high-speed rotation of the drive motor into the low-speed, high-torque rotation required by screw rod 3. The reducer's torque-increasing effect ensures that screw rod 3 operates in a stable and powerful state.

[0044] The other end of the screw rod 3 is rotatably engaged with the bearing seat, ensuring that the screw rod 3 can rotate freely while being able to withstand the various forces and moments generated during operation. The bearing seat is also designed to provide a tight seal to prevent sewage and sludge from seeping into the collection chamber 2 and causing corrosion and damage to the equipment.

[0045] In one embodiment, Figure 6As shown, two groups of support frames 8 are also provided inside the collecting bin 2; the support frames 8 include a fixing plate 81 and a support ring 82 connected to each other, the fixing plate 81 is fixed to the collecting bin 2 by bolts, the support ring 82 is located at the bottom of the collecting bin 2, and the support ring 82 is sleeved with the side wall of the spiral rod 3.

[0046] The fixing plate 81 is bolted to the side wall of the collection bin 2, ensuring the stability and reliability of the support frame 8. The support ring 82 is located at the bottom of the collection bin 2. Its design shape and size match the side wall of the spiral rod 3, allowing the spiral rod 3 to smoothly pass through the support ring 82 during rotation without shaking or deflection.

[0047] Specifically, the agitator 6 in this embodiment includes a fixed frame 61 disposed on the treatment tank 1, a second driving member 62 being disposed on the fixed frame 61, a stirring rod 63 being rotatably disposed at the bottom of the fixed frame 61, and the second driving member 62 being connected to the stirring rod 63 and used to drive the stirring rod 63 to rotate. A through hole for mounting the stirring rod 63 is opened on the fixed frame 61.

[0048] The driving member 62 includes a driving motor and a reducer. The reducer and the driving motor are both arranged on the fixing frame 61 . The output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the stirring rod 63 .

[0049] The fixing frame 61 serves as the supporting structure of the entire agitator, ensuring the stability and safety of the agitator during operation. The through hole provided on the fixing frame 61 allows the stirring rod 63 to rotate freely at the bottom of the fixing frame 61.

[0050] The drive motor is mounted on a fixed frame 61, its output shaft tightly connected to the input shaft of the reducer. The reducer converts the high-speed rotation of the drive motor into the low-speed, high-torque rotation required by the stirring rod 63, meeting the actual stirring requirements. The reducer's output shaft is directly connected to the stirring rod 63, driving the stirring rod 63 in rotation. The stirring rod 63 is the core component of the agitator 6, and its rotational motion thoroughly mixes the wastewater with microorganisms or chemicals.

[0051] Further, such as Figure 5 As shown, in this embodiment, the stirring rod 63 includes a rotating shaft 631 rotatably set on the fixed frame 61, and a plurality of stirring blades 632 are arranged in a ring shape on the rotating shaft 631; the scraper 7 is arranged at the bottom end of the rotating shaft 631, and the scraper 7 is in contact with the bottom wall inside the treatment tank 1.

[0052] The rotating shaft 631, the main body of the stirring rod 63, is connected to the output of the reducer via a through-hole in the fixing frame 61 and can rotate freely under the drive motor. The stirring blades 632 are arranged at a predetermined spacing and angle, producing a strong stirring effect when the rotating shaft 631 rotates.

[0053] A scraper 7 is provided at the bottom end of the rotating shaft 631 . The scraper 7 is in close contact with the bottom wall inside the treatment tank 1 and moves with the rotation of the rotating shaft 631 , so that the scraper 7 can effectively scrape away the silt and sediment at the bottom of the treatment tank 1 .

[0054] The material and shape of the scraper 7 may also be adjusted according to the specific conditions of the bottom of the treatment tank 1 to ensure that it can fully contact and scrape away the silt and sediment at the bottom.
