Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a multiple treatment device for food processing sewage. Background Art

[0002] The sewage discharged from slaughterhouses and meat processing workshops contains a large amount of blood, protein and meat residues. If the discharged sewage is not treated, it will seriously pollute surface water and groundwater, consume dissolved oxygen in the water, affect the survival of aquatic organisms, destroy the ecological balance of the water body, and even cause eutrophication of the water body. The existing flotation machine is used to treat this type of sewage. By adding chemicals to the sewage to form flocculated impurities, the flocculated impurities are floated on the liquid surface by dissolved air water, and the floating impurities are driven and collected by a circulating scraper;

[0003] In the existing flotation machine technology, chemicals are often added to sewage to form flocculated impurities, which are then floated to the liquid surface using dissolved air water, and then the floating impurities are driven and collected by a circulating scraper. However, the existing scraper design has certain limitations. Specifically, the height of the scraper is generally fixed and cannot be automatically adjusted according to the thickness of the floating objects in the sewage. When the thickness of the floating impurities in the sewage is large, the scraper with a fixed height may not be able to effectively scrape off all the floating objects, resulting in the impurities not being completely removed, thereby reducing the treatment efficiency and water purification effect. In addition, different types of sewage may produce floating impurities of different concentrations, and the scraper with a fixed height cannot adapt to such changes, further affecting the overall treatment capacity of the flotation machine. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the purpose of the present invention is to propose a multiple treatment device for food processing wastewater, which can achieve efficient separation and removal of floating impurities through a scraping assembly, a partition plate and a driving assembly, especially through a scraper assembly with adjustable height, which can be flexibly adjusted according to changes in the thickness of floating objects to ensure the complete removal of floating impurities.

[0006] To achieve the above-mentioned object, the present invention proposes a multiple treatment device for food processing wastewater, comprising an air flotation machine housing, a support frame, a driving assembly, a floating object separation mechanism and a collection housing, wherein the support frame is fixedly connected to the top of the air flotation machine housing, the driving assembly is installed on the top of the support frame, the floating object separation mechanism comprises a primary partition plate, a supporting side plate, a scraping assembly, a secondary partition plate and a sealing plate, wherein the primary partition plate and the secondary partition plate are distributed front and back, and are both fixedly connected to the end of the driving assembly, the top of the primary partition plate is symmetrically provided with an assembly groove, the supporting side plate is symmetrically fixedly connected to the inner wall of the assembly groove, the scraping assembly is installed on the inner wall of the supporting side plate, both sides of the air flotation machine housing are provided with a discharge groove, the primary partition plate and the secondary partition plate are both slidably clamped in the discharge groove, the sealing plate is symmetrically fixedly connected to the bottom of the primary partition plate and the secondary partition plate, and the sealing plate is slidably clamped on the inner wall of the air flotation machine housing and is located on one side of the discharge groove, and the primary partition plate and the secondary partition plate are both blunt-angle V-shaped structures as a whole.

[0007] The multi-treatment device for food processing wastewater of the present invention drives the primary partition plate and the secondary partition plate to slide in the discharge groove through the driving component, and the scraping component circulates along the inner wall of the supporting side plate. After the wastewater enters the air flotation machine housing, the floating impurities formed by flocculation are concentrated to the liquid surface under the action of air flotation. The scraping component gradually pushes the floating impurities from the primary partition plate to the secondary partition plate through the cyclic motion, and finally guides them to the discharge groove for collection and treatment. The sealing plate is tightly fitted with the inner wall of the housing to ensure that the wastewater and the floating impurities do not leak during the sliding of the partition plate, thereby enhancing the sealing and operation stability of the device. The device optimizes the concentration and guiding path of the floating impurities and improves the separation efficiency by arranging the primary partition plate and the secondary partition plate with an obtuse angle V shape. The sliding clamping design makes the position of the partition plate flexible and adjustable to adapt to the floating impurity layer of different thicknesses, thereby overcoming the problem that the traditional fixed scraper is difficult to handle thicker floating objects. At the same time, the sliding of the partition plate and the linkage of the scraping component can effectively cope with the change of the concentration of floating objects in the wastewater, ensure the thorough removal of the floating impurities, thereby solving the problems of low treatment efficiency and residual floating impurities in the background technology.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0034] The following describes a multiple treatment device for food processing wastewater according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0035] like Figure 1-Figure 8 As shown, the multiple treatment device for food processing wastewater according to the embodiment of the present invention may include an air flotation machine housing 1 , a support frame 2 , a driving assembly 3 , a floating object separation mechanism 4 and a collection housing 5 .

[0036] The support frame 2 is fixedly connected to the top of the air flotation machine housing 1 , and the driving assembly 3 is installed on the top of the support frame 2 .

[0037] It should be noted that the support frame 2 described in this embodiment is made of high-strength metal material, and a reinforcing rib structure is provided at the position fixedly connected to the air flotation machine housing 1 to enhance the overall stability.

[0038] Furthermore, if Figure 1 As shown, a mounting plate 15 is installed at the inner bottom of the air flotation machine housing 1, and air outlet heads 16 are installed at equal intervals on the top of the mounting plate 15. The two ends of the air flotation machine housing 1 are respectively fixedly connected with an inlet plate 11 and an outlet plate 12, and the position of the outlet plate 12 is lower than that of the inlet plate 11.

[0039] It should be noted that the mounting plate 15 described in this embodiment is made of corrosion-resistant material and is fixed to the bottom of the inner side of the air flotation machine housing 1 by a detachable connection method, which is convenient for cleaning and replacing the air outlet head 16. The air flotation machine introduces dissolved air water into the air outlet head 16 through a dissolved air release device or dissolved air system connected below the air outlet head 16, thereby discharging fine bubbles.

The pressure pump sends dissolved air water into the air outlet head 16 installed on the mounting plate 15, and evenly releases bubbles through the fine holes or microporous structure of the air outlet head 16, thereby achieving effective distribution of bubbles and adhesion of suspended impurities in water.

[0040] The floating object separation mechanism 4 includes a primary partition plate 41 , a supporting side plate 42 , a scraping assembly 43 , a secondary partition plate 44 and a sealing plate 45 .

[0041] The primary partition plate 41 and the secondary partition plate 44 are distributed front and back, and are both fixedly connected to the ends of the driving assembly 3 .

[0042] Furthermore, if Figure 1 As shown, the primary partition plate 41 and the secondary partition plate 44 are both of an obtuse-angle V-shaped structure as a whole.

[0043] Furthermore, if Figure 1 As shown, the inner wall of the primary partition plate 41 and the bottom of the secondary partition plate 44 are fixedly connected with convex plates, and the inner walls of the primary partition plate 41 and the secondary partition plate 44 and the outer walls of the convex plates respectively abut against the inner walls of the discharge groove 14 on both sides.

[0044] It should be noted that the primary partition plate 41 and the secondary partition plate 44 described in this embodiment are made of high-strength corrosion-resistant materials, and reinforcing ribs are arranged at the corners of the V-shaped structure to enhance the overall anti-deformation capability. The convex plate and the partition plate are fixedly connected by welding, and at the same time, a flexible sealing layer is arranged on the outer wall thereof to ensure a close fit with the inner wall of the discharge groove 14 to prevent leakage in the gap for easy maintenance.

[0045] It should be understood that the position of the raised plate should be lower than the bottom of the float.

[0046] The top of the primary partition plate 41 is symmetrically provided with an assembly groove 411 , the supporting side plates 42 are symmetrically fixedly connected to the inner wall of the assembly groove 411 , and the scraping assembly 43 is installed on the inner wall of the supporting side plates 42 .

[0047] It should be noted that the top of the primary partition plate 41 described in this embodiment is fixedly connected with an upper convex plate, and the assembly groove 411 is opened on the upper convex plate.

[0048] A discharge groove 14 is provided on both sides of the air flotation machine housing 1, and the primary partition plate 41 and the secondary partition plate 44 are both slidably engaged in the discharge groove 14, and the sealing plate 45 is symmetrically fixedly connected to the bottom of the primary partition plate 41 and the secondary partition plate 44, and the sealing plate 45 is slidably engaged with the inner wall of the air flotation machine housing 1 and is located on one side of the discharge groove 14.

[0049] It should be noted that the inner wall of the discharge trough 14 described in this embodiment is provided with a slide rail structure, which cooperates with the sliding clamping parts of the primary partition plate 41 and the secondary partition plate 44 to ensure stability and smoothness during the sliding process.

[0050] Specifically, in order to ensure the effective removal of floating objects, the top of the primary partition plate 41 is symmetrically provided with an assembly groove 411, the supporting side plate 42 is symmetrically fixedly connected to the inner wall of the assembly groove 411, the scraping assembly 43 is installed on the inner wall of the supporting side plate 42, and discharge grooves 14 are provided on both sides of the air flotation machine housing 1. The primary partition plate 41 and the secondary partition plate 44 are both slidably engaged in the discharge groove 14, the sealing plate 45 is symmetrically fixedly connected to the bottom of the primary partition plate 41 and the secondary partition plate 44, and the sealing plate 45 is slidably engaged in the inner wall of the air flotation machine housing 1 and is located on one side of the discharge groove 14, and then the primary partition plate 41 and the secondary partition plate 44 are driven by the driving assembly 3 to slide in the discharge groove 14, and at the same time, the scraping assembly 43 circulates along the inner wall of the supporting side plate 42. After the sewage enters the air flotation machine housing 1, the floating impurities formed by flocculation are concentrated to the liquid surface under the action of air flotation, and the scraping assembly 43 pushes the floating impurities gradually from the primary partition plate 41 to the secondary partition plate 44 through a circular motion, and finally guides them to the discharge trough 14 for collection and treatment. The sealing plate 45 fits tightly against the inner wall of the shell to ensure that sewage and floating impurities do not leak during the sliding of the partition plate, thereby enhancing the sealing and operating stability of the device. The device optimizes the concentration and guiding path of floating impurities and improves the separation efficiency by setting the primary partition plate 41 and the secondary partition plate 44 with an obtuse angle V. The sliding card design makes the position of the partition plate flexible and adjustable to adapt to floating impurity layers of different thicknesses, thereby overcoming the problem that the traditional fixed scraper 434 is difficult to handle thicker floating objects. At the same time, the sliding of the partition plate and the linkage of the scraping component 43 can effectively cope with the changes in the concentration of floating objects in the sewage, ensuring the thorough removal of floating impurities, thereby solving the problems of low processing efficiency and residual floating impurities in the background technology.

[0051] In one embodiment of the present invention, Figure 1-Figure 8 As shown, the driving assembly 3 includes a first driving device 31, a driving arm 32 and a reinforcing arm 33, wherein the first driving device 31 is installed on the top of the support frame 2, the output end of the first driving device 31 passes through the top of the support frame 2, and is fixedly connected to one end of the driving arm 32, the top of the reinforcing arm 33 is fixedly connected to the other end of the driving arm 32, and the two ends of the reinforcing arm 33 are respectively fixedly connected to the inner wall of the first partition plate 41 and the outer wall of the secondary partition plate 44.

[0052] It should be noted that the first driving device 31 described in this embodiment is a hydraulic cylinder.

[0053] Specifically, in order to be able to collect floating objects of different thicknesses, the first driving device 31 is installed on the top of the support frame 2, the output end of the first driving device 31 passes through the top of the support frame 2, and is fixedly connected to one end of the driving arm 32, the top of the reinforcing arm 33 is fixedly connected to the other end of the driving arm 32, and the two ends of the reinforcing arm 33 are respectively fixedly connected to the inner wall of the primary partition plate 41 and the outer wall of the secondary partition plate 44, and then the connected driving arm 32 is driven to perform lifting movement through the output of the first driving device 31, and at the same time, the reinforcing arm 33 fixed at the other end of the driving arm 32 is used to lift the floating objects. The power is transmitted to the primary partition plate 41 and the secondary partition plate 44. During the driving process, the two ends of the reinforcement arm 33 are respectively connected to the inner wall of the primary partition plate 41 and the outer wall of the secondary partition plate 44, thereby realizing the synchronous height adjustment of the two partition plates. Through this adjustment, the primary partition plate 41 and the secondary partition plate 44 can be flexibly raised and lowered according to the change of the thickness of the floating objects, so that the partition plates are always kept in the best working position, ensuring the guiding, concentration and removal effect of the floating impurities. Through the height-adjustable partition plate structure, the device can adapt to floating impurity layers of different thicknesses, thereby efficiently removing floating objects on the liquid surface.

[0054] In one embodiment of the present invention, Figure 1-Figure 8 As shown, the scraping assembly 43 includes a second driving device 431, a driving rod 432, a driving belt 433 and a scraper 434, wherein the second driving device 431 is symmetrically installed at both ends of the inner wall of the primary partition plate 41, the driving rod 432 is symmetrically rotatably connected to the inner walls of the two supporting side plates 42, the driving belt 433 is sleeved on the driving rod 432, and a plurality of scrapers 434 are fixedly connected to the outer wall of the driving belt 433 at equal intervals.

[0055] It should be noted that the second driving device 431 described in this embodiment is a cylinder.

[0056] Specifically, in order to collect floating objects efficiently, the second driving device 431 is symmetrically installed at both ends of the inner wall of the first-level partition plate 41, the driving rod 432 is symmetrically rotatably connected to the inner walls of the two supporting side plates 42, the driving belt 433 is sleeved on the driving rod 432, and multiple scrapers 434 are fixedly connected to the outside of the driving belt 433 at equal intervals. Then, by starting the second driving device 431, it drives the driving rod 432 to rotate, and then drives the driving belt 433 to rotate, thereby driving multiple scrapers 434 to scrape the floating objects. At the same time, in conjunction with the V-shaped structure of the first-level partition plate 41, the floating objects can be guided to the inside of the collection shell 5, so that the collection of floating objects is more efficient. At the same time, the floating objects can be further collected at a secondary level through the secondary partition plate 44, so that the solid-liquid separation effect is better.

[0057] It should be understood that the two sides of the air flotation machine shell 1 are symmetrically fixedly connected with the collecting shell 5, the end of the collecting shell 5 is fixedly connected with the discharge pipe 51, the interior of the collecting shell 5 is provided with a filter screen, the filter screen is fixedly connected along the length direction of the collecting shell 5, and an elastic sealing gasket is provided at the inner wall edge of the sealing plate 45. The elastic sealing gasket is used to enhance the sealing performance of the device to prevent sewage or floating objects from leaking to the outside of the device. The inner wall of the air flotation machine shell 1 is symmetrically fixedly connected with the support plate 13, and the inner wall of the primary partition plate 41 is symmetrically fixedly connected with the guide plate 412, and the end of the guide plate 412 is slidably clamped on the side wall of the support plate 13.

[0058] In summary, the multi-treatment device for food processing wastewater of the embodiment of the present invention drives the primary partition plate 41 and the secondary partition plate 44 to slide in the discharge tank 14 through the driving component 3, and at the same time, the scraping component 43 circulates along the inner wall of the supporting side plate 42. After the sewage enters the air flotation machine housing 1, the floating impurities formed by flocculation are concentrated to the liquid surface under the action of air flotation. The scraping component 43 pushes the floating impurities from the primary partition plate 41 to the secondary partition plate 44 step by step through the circular motion, and finally guides them to the discharge tank 14 for collection and treatment. The sealing plate 45 is tightly fitted with the inner wall of the housing to ensure that the sewage and the floating impurities are separated during the sliding process of the partition plate. No leakage occurs, and the sealing and operating stability of the device are enhanced. The device optimizes the concentration and guiding path of floating impurities and improves the separation efficiency by setting a blunt-angle V-shaped primary partition plate 41 and a secondary partition plate 44. The sliding card design makes the position of the partition plate flexibly adjustable to adapt to floating impurity layers of different thicknesses, overcoming the problem that the traditional fixed scraper 434 is difficult to handle thicker floating objects. At the same time, the sliding of the partition plate and the linkage of the scraping component 43 can effectively respond to changes in the concentration of floating objects in the sewage and ensure the complete removal of floating impurities, thereby solving the problems of low processing efficiency and residual floating impurities in the background technology.
