Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sedimentation-type multi-stage sewage treatment device. Background Art

[0002] In the construction industry, mortar is widely produced and used. However, mortar processing plants produce a large amount of wastewater during the production process. The wastewater contains cement, sand, admixtures, chemical additives and other impurities.

[0003] Traditional wastewater treatment methods for mortar processing plants are often relatively simple and extensive. Common methods include sedimentation, which relies solely on gravity to precipitate solid particles, but is ineffective in removing fine particles and soluble pollutants. Filtration can remove larger particles, but is prone to clogging and requires frequent replacement of filter materials, increasing costs and maintenance workload. Current sewage treatment equipment generally uses sedimentation to treat mortar plant sewage, discharging the mud and solids after settling. However, this sedimentation method has the following defects: First, the direct sedimentation method can easily fill up the sedimentation tank due to excessive impurities, resulting in frequent cleaning. Second, during sedimentation, a large number of impurities will float up, and manual salvage is labor-intensive and will cause blockage of the drain outlet. Based on this, we designed a method that can first filter the sewage to remove a large amount of solid impurities, and then improve the purification effect through multi-stage coagulation and sedimentation.

DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0027] like Figure 1-Figure 5 As shown, a sedimentation-type multi-stage sewage treatment device includes a tank body 1, a first trough 2, a filtering mechanism 3, a grille mechanism 4 and a sedimentation and flocculation mechanism 9. The interior of the tank body 1 is respectively provided with a first trough 2, a second trough 5, a third trough 6, a fourth trough 8 and a fifth trough 10. The interior of the first trough 2 is provided with a filtering mechanism 3 and a grille mechanism 4. The filtering mechanism 3 includes a support frame 307, a transmission chain 304, a stainless steel mesh belt 305 and a feed hopper 302. The support frame 307 is provided on the rectangular opening of the first trough 2, and the upper part of the support frame 307 is provided with a transmission chain 304 and a stainless steel mesh belt 305, and the upper part of the stainless steel mesh belt 305 is provided with a feed hopper 302; the first trough 2 is connected to the second trough 5 through a first water guide pump, and the interior of the second trough 5 is provided with a sedimentation and flocculation mechanism 9, which includes a material tank 901, a carrying platform 902, Filter plate 906 and disturbance frame 909, the material tank 901 is arranged in the second material trough 5 through the supporting platform 902, and a disturbance frame 909 connected to the first drive motor 908 is arranged inside the material tank 901; the material tank 901 is a cylindrical hollow cavity structure with an upper opening, the material tank 901 is arranged inside the supporting platform 902, and water guide grooves are respectively provided at the four corners of the supporting platform 902, and a filter plate 906 is provided on the upper part of the water guide groove; a fixed bracket 907 is provided on the upper part of the material tank 901, and a first drive motor 908 is provided on the fixed bracket 907, and the output shaft of the first drive motor 908 is connected to the disturbance frame 909 through a coupling; a connecting support 904 is provided on the side of the second material trough 5, and a water pipe 905 is provided on the connecting support 904, one end of the water pipe 905 extends into the interior of the material tank 901, and a control valve 903 is provided on the other end of the water pipe 905.

[0028] It should be noted that, in the process of mortar production, a large amount of sewage is generally produced. These are generally discharged into the river after simple treatment, which will cause pollution. In addition, the use of direct sedimentation will introduce a large amount of solid impurities into the sedimentation tank, which can easily cause accumulation at the bottom of the tank, requiring operators to clean it frequently. Based on this, we have designed a device that filters the sewage during its introduction process in order to improve the efficiency of sewage purification.

[0029] It should be further explained that a support frame 307 is set at one end of the first trough 2, and a transmission chain 304 and a stainless steel mesh belt 305 are set on the sprocket of the support frame 307. The sewage enters the stainless steel mesh belt 305 through the feed hopper 302 and is filtered by the stainless steel mesh belt 305. The stainless steel mesh belt 305 is driven by the first drive motor 306 to automatically introduce the filtered solid impurities, eliminating the need for manual salvage and cleaning, thereby improving work efficiency.

[0030] It should be further explained that a sedimentation and flocculation mechanism 9 is provided inside the second trough 5 to introduce the filtered sewage into the material tank 901. After static sedimentation, the heavier particles will be deposited in the lower layer and discharged through the water pipe 905. Some floating objects remaining on the water stains will be slowly disturbed by the disturbance frame 909 and introduced into the water trough of the supporting platform 902 for discharge, and then enter the third trough 6.

[0031] It should be further explained that in order to discharge sewage in layers, a chamber structure is formed between our material tank 901 and the trough body of the second material trough 5. The water stains discharged from the water guide trough enter this chamber, and then enter the third material trough 6 through the first water guide trough 13. The water is discharged from the bottom to the top, filling the third material trough 6, and flocculation treatment is performed again by adding flocculants.

[0032] like Figure 1 and Figure 2 As shown, the grid mechanism 4 includes a lifting bracket 401, a transmission belt 404, a lifting plate 405 and a second drive motor 403. The lifting bracket 401 is arranged at one end of the first material trough 2. The transmission belt 404 is arranged inside the lifting bracket 401, and a number of lifting plates 405 with filtering holes are arranged on the transmission belt 404; two polymer plates 402 are symmetrically arranged inside the first material trough 2 to form a gathering structure close to the lifting bracket 401; the second drive motor 403 is arranged on the lifting bracket 401, and the second drive motor 403 is connected to the transmission roller of the transmission belt 404.

[0033] It should be noted that the grid mechanism 4 is provided to remove floating objects floating on the first trough 2. The second drive motor 403 on the lifting bracket 401 drives the transmission belt 404, and then the impurities are lifted and discharged under the guidance of the lifting plate 405, which is convenient for subsequent sedimentation and flocculation.

[0034] like Figure 1-Figure 5As shown, a spreading mechanism 7 is provided on the upper part of the third material trough 6, and the spreading mechanism 7 includes a connecting arm 702, a material trough 701 and a material guide pipe 703. The material trough 701 is provided on the connecting arm 702, and a rectangular opening is provided at the bottom of the material trough 701, and a material guide pipe 703 is provided inside the rectangular opening; the material guide pipe 703 is rotatably provided on the bearing seat of the rectangular opening, and one end of the material guide pipe 703 is connected to the third drive motor through a connecting piece; a plurality of material troughs are provided on the upper part of the material guide pipe 703; a first discharge port 704 is provided at one end of the third material trough 6, and a discharge conduit is provided inside the first discharge port 704.

[0035] It should be noted that the setting of the spreading mechanism 7 is to spread the flocculant and re-flocculate the water stains. In order to introduce them evenly, we set a rectangular opening and a material guide pipe 703 at the bottom of the material trough 701, and set multiple material holes on the material guide pipe 703 to achieve uniform material discharge under the rotation of the material guide pipe 703.

[0036] like Figure 1-Figure 5 As shown, the third trough 6 is connected to the fourth trough 8 through the first water trough 13, and a second water trough 12 is provided between the fourth trough 8 and the fifth trough 10; a water guide hole is provided at the bottom of the second trough 5, and the water guide hole is connected to the chamber of the third trough 6; the feed hopper 302 is connected to the first trough 2 through the connecting plate 301 and screws at the bottom.

[0037] It should be noted that the fourth trough 8 and the fifth trough 10 are provided to facilitate the filtration and settling of the water stains after flocculation, thereby completing the sewage treatment through sedimentation.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
