Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a quick-install magnetic seed recovery machine. Background Art

[0002] People generate a lot of sewage in their daily life. If the sewage is discharged directly without treatment, it will cause serious pollution to the environment. At present, one of the more common sewage treatment technologies is magnetic flocculation water treatment technology, which uses magnetic seed media to cause pollutants in sewage to aggregate into flocs, thereby separating the dirt in the sewage. Since magnetic seeds are expensive and can be recycled and reused, in order to reduce treatment costs, treatment plants usually use magnetic seed recovery machines to recycle and reuse magnetic seeds in sludge.

[0003] The magnetic seed recovery machine uses a magnetic drum to absorb and separate magnetic seeds. When assembling the equipment, the magnetic drum usually needs to be hoisted from the upper end of the magnetic seed recovery machine into the main body of the machine. Therefore, the main body of the machine is usually opened at the upper end and then closed with a cover. However, the existing magnetic seed recovery machines usually use welding to fix the cover to the main body of the machine. Therefore, after the equipment is assembled, an additional welding process is required. The equipment assembly is more troublesome, less efficient, and not beautiful. Moreover, in the later use process, if the magnetic drum needs to be disassembled for maintenance due to equipment failure or other reasons, the cover needs to be cut off, which is time-consuming and labor-intensive and there is also a risk of damaging the magnetic seed recovery machine.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to make new innovations. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] Example

[0031] This embodiment provides a quick-install magnetic seed recovery machine, which includes a main body 1 and a magnetic drum 3. The main body 1 includes a box body 11 and a cover body 12. Figures 1 to 3 shown.

[0032] The box body 11 is divided into a high shear chamber 113, a magnetic drum chamber 114 and a stirring chamber 115 in sequence along its length direction. Figure 4 As shown. A flow channel 1161 is provided near the upper end on the first partition plate 116 between the high shear chamber 113 and the magnetic drum chamber 114, and the magnetic seed sludge mixture in the high shear chamber 113 flows into the magnetic drum chamber 114 through the flow channel 1161. A shearing paddle 7 is provided in the high shear chamber 113, which is driven by a high-speed motor 8 and rotates at a high speed in the high shear chamber 113, thereby shearing and dispersing the sludge magnetic seed flocs flowing into the high shear chamber 113 at a high speed. Since the high shear effect on the sludge magnetic seed flocs is a conventional technology and is not the focus of the protection requested in this application, it will not be described in detail here.

[0033] The magnetic drum 3 is rotatably disposed in the magnetic drum chamber 114. The axial direction of the magnetic drum 3 is consistent with the width direction of the box body 11. Both ends of the rotating shaft of the magnetic drum 3 are connected to the box body 11 through the sealing plate assembly 31. Specifically, mounting notches 112 are correspondingly disposed on the opposite sides of the box body 11, that is, the two side walls in the width direction. The mounting notches 112 pass through the top of the box body 11. Figure 5 A sealing plate assembly 31 is respectively arranged at the two installation slots 112, and the two ends of the rotating shaft of the magnetic drum 3 respectively pass through the two sealing plate assemblies 31 and are rotatably connected to the supporting structures arranged on both sides of the box body 11, such as Figures 1 to 3 In the preferred solution shown in , a bearing seat 5 is fixedly arranged on each side of the box body 11, and both ends of the rotating shaft of the magnetic drum 3 pass through the sealing plate assembly 31 and are installed in cooperation with the corresponding bearing seat 5, so as to ensure that the magnetic drum 3 can stably rotate in the magnetic drum chamber 114. A seal is arranged between the rotating shaft and the sealing plate assembly 31.

[0034] In a further preferred embodiment, the sealing plate assembly 31 preferably includes a U-shaped frame 311 and a sealing plate 312. Figure 6 and Figure 7As shown. The U-shaped frame 311 is arranged at the installation slot 112 of the box body 11 and is fixedly connected to the box body 11, and the opening of the U-shaped frame 311 faces upward. The sealing plate 312 is fixedly arranged on the side of the U-shaped frame 311 away from the box body 11, and the sealing plate 312 and the U-shaped frame 311 are preferably locked and fixed by fasteners such as bolts. The rotating shaft of the magnetic drum 3 passes through the sealing plate 312 and is rotatably connected to the corresponding supporting structure. When assembling the magnetic seed recovery machine, the sealing plate assembly 31 can be assembled first and then the U-shaped frame 311 can be welded and fixed to the box body 11. With such a design, it is easier to install and debug the magnetic drum 3 during assembly, and it is also convenient to disassemble, replace, repair and maintain the magnetic drum 3 while ensuring closure. In addition, the U-shaped frame 311 structure can also play a role in strengthening the edge strength of the installation slot 112. A seal is set between the rotating shaft and the sealing plate 312, and it is further preferably sealed by an oil seal. For example Figure 7 As shown in , an oil seal seat 313 is fixedly arranged on the sealing plate 312 to install and fix the oil seal. Since the oil seal is a prior art and is not the focus of the protection requested by this application, it will not be described in detail here.

[0035] In a further preferred embodiment, a liquid receiving tank 4 is preferably provided below the sealing plate assembly 31, such as Figures 1 to 3 As shown, it can be used to receive the leaked liquid, thereby ensuring the cleanliness of the equipment layout site. Furthermore, a drain pipe can be connected to the liquid receiving tank 4 to automatically discharge the leaked liquid to a specified position, thereby eliminating the need to manually dump the leaked liquid in the liquid receiving tank 4.

[0036] An arc-shaped partition plate 117 matching the magnetic drum 3 is disposed below the magnetic drum 3 in the magnetic drum chamber 114, and the arc-shaped partition plate 117 is welded and fixed to the width side walls of the box body 11 respectively. One end of the arc-shaped partition plate 117 in the length direction extends to the flow channel opening 1161, so that the magnetic seed sludge mixture in the high shear chamber 113 can flow into between the magnetic drum 3 and the arc-shaped partition plate 117. The magnetic drum 3 is conventional technology, and its specific structure is not the focus of protection of this application, so it will not be described in detail here. The magnetic drum 3 has magnetic force and can be driven to rotate by the magnetic drum drive motor, that is, Figure 4 When the magnetic drum 3 rotates in the clockwise direction as shown in the figure, the magnetic seeds in the magnetic seed-sludge mixed liquid flowing into the space between the magnetic drum 3 and the arc-shaped partition plate 117 will be adsorbed on the surface of the magnetic drum 3.

[0037] A passage opening 1181 is provided near the upper end of the second partition plate 118 between the magnetic drum chamber 114 and the stirring chamber 115. A scraper 6 is provided between the magnetic drum 3 and the stirring chamber 115, one end of the scraper 6 extends to the surface of the magnetic drum 3, and the other end of the scraper 6 extends obliquely downward into the stirring chamber 115. When the magnetic drum 3 is driven by the magnetic drum driving motor to rotate clockwise, the scraper 6 scrapes the magnetic seeds adsorbed on the magnetic drum 3 from the surface of the magnetic drum 3, and the scraped magnetic seeds will fall into the stirring chamber 115. Further preferably, the scraper 6 is an adjustable structure, such as Figure 4 and Figure 5 As shown in , the scraper 6 includes a fixed plate 61 and an adjustment plate 62, and the fixed plate 61 is fixedly arranged with the box body 11. The adjustment plate 62 is adjustably arranged on the fixed plate 61. Specifically, a plurality of fixing holes are correspondingly arranged on the adjustment plate 62 and the fixed plate 61 respectively along the length direction, and then they are locked and fixed by fasteners such as bolts. By setting the fixing holes on the adjustment plate 62 or the fixed plate 61 as strip holes extending along the width direction thereof, the position of the adjustment plate 62 on the fixed plate 61 can be adjusted, so as to adapt to the magnetic drum 3 of different diameters; and during long-term use, if the scraper 6 is worn, the adjustment plate 62 can be fine-tuned to make it fit the surface of the magnetic drum 3 again, without replacing the entire scraper 6.

[0038] The bottom end of the arc-shaped partition plate 117 is provided with a mud discharge port 1171. Figure 4 As shown, it is used to discharge sludge. A drainage baffle 119 is arranged between the arc baffle 117 and the second partition 118, and the drainage baffle 119 is respectively welded and fixed to the arc baffle 117, the second partition 118 and the two side walls of the box body 11, thereby forming a water tank structure. A water inlet 1172 is arranged near the other end of the arc baffle 117, as shown in FIG. Figure 4 and Figure 5 As shown, the water flowing through the magnetic drum 3 flows into the water tank structure through the water inlet 1172 and then is discharged through the drain outlet 1191 on the water tank structure.

[0039] The stirring chamber 115 is provided with a stirring paddle 9, which can be driven by a stirring drive motor 10 to stir the magnetic seeds dropped into the stirring chamber 115, so that the magnetic seeds and the water in the stirring chamber 115 form a magnetic seed mixed liquid, which is finally pumped by a pump and added to a designated device for reuse. Since the stirring of the magnetic seeds is a conventional technology and is not the focus of the protection requested by this application, it will not be described in detail here.

[0040] The top of the box body 11 is provided with a flange structure 111 extending outward, and the cover body 12 is covered on the top of the box body 11. The cover body 12 and the flange structure 111 are clamped together by a clamp assembly 2. The clamp assembly 2 preferably includes a hoop body 21 and a pressing assembly 22. The hoop body 21 is clamped around the periphery of the cover body 12 and the flange structure 111. Adjusting the pressing assembly 22 can drive the hoop body 21 to tighten inward and thus clamp the cover body 12 and the flange structure 111. The hoop body 21 includes at least one hoop body segment, and the cross-sectional shape of the hoop body segment is a U-shape with the opening inward, and the hoop body segment is clamped around the periphery of the cover body 12 and the flange structure 111. For example Figures 1 to 5 In the preferred solution shown in the figure, the high-speed motor 8 is fixedly installed at the top of the high-shear chamber 113 by setting a mounting plate 120. The top of the side wall of the magnetic drum chamber 114 and the top of the side wall of the stirring chamber 115 are respectively extended outward with a flange structure 111. Due to the solution shown in the figure, the side wall of the shear chamber is designed to be high, which will cause interference, so the top of the side wall of the magnetic drum chamber 114 is not provided with the flange structure 111 at the corresponding high-shear chamber 113. However, in the specific implementation, if the side wall of the high-shear chamber 113 is designed to be low and no interference will occur, the flange structure 111 can also be provided at the top of the side wall of the magnetic drum chamber 114 at the corresponding high-shear chamber 113.

[0041] The cover body 12 covers the upper ends of the magnetic drum chamber 114 and the stirring chamber 115, and the outer edge of the cover body 12 is preferably aligned with the outer edge of the flange structure 111. It should be noted that the cover body 12 described in this embodiment can be an integral cover plate or can be composed of multiple cover plates spliced ​​together according to the design.

[0042] by Figure 1Taking the structure shown in as an example, the hoop body 21 includes a first hoop body segment 211 and a second hoop body segment 212. The first hoop body segment 211 and the second hoop body segment 212 are respectively U-shaped and are relatively clamped at the upper ends of the magnetic drum chamber 114 and the stirring chamber 115. The front end of the first hoop body segment 211 and the front end of the second hoop body segment 212 are correspondingly arranged at the side of the magnetic drum chamber 114 away from the stirring chamber 115 and have a distance. The rear end of the first hoop body segment 211 and the rear end of the second hoop body segment 212 are correspondingly arranged at the side of the stirring chamber 115 away from the magnetic drum chamber 114 and have a distance. Adjusting the pressing component 22 can drive the front ends and the rear ends of the two hoop body segments to be relatively close to each other, thereby tightening the hoop body 21 inward. The pressing component 22 is preferably a bolt 221 and a nut 222. Of course, the pressing component 22 can also be other structures, such as a buckle. The front end and the rear end of the first hoop body segment 211 are respectively provided with an approaching plate structure, which are defined as a first approaching plate structure 2111 and a second approaching plate structure 2112; the front end and the rear end of the second hoop body segment 212 are respectively provided with an approaching plate structure, which are defined as a third approaching plate structure 2121 and a fourth approaching plate structure 2122. Figure 8 and Fig. 9 As shown. Bolt holes are respectively provided on each approach plate structure. A nut 222 is respectively welded and fixed to the front end of the first hoop body section 211 and the front end of the second hoop body section 212 of the mounting plate 120. Figure 3 As shown, a bolt 221 is inserted into each of the first approach plate structure 2111 and the third approach plate structure 2121, and the bolt 221 is screwed with a corresponding nut 222. By rotating the bolt 221, the front end of the first hoop body segment 211 or the front end of the second hoop body segment 212 can be driven to tighten inward. By inserting a bolt 221 into the second approach plate structure 2112 and the fourth approach plate structure 2122 and screwing a nut 222, as shown in FIG. Fig. 9 and Fig.10 As shown, by rotating the nut 222, the second approaching plate structure 2112 and the fourth approaching plate structure 2122 can be driven to approach each other, thereby driving the rear end of the first hoop body segment 211 and the rear end of the second hoop body segment 212 to clamp inward.

[0043] Of course, the above is only a preferred solution. In other embodiments, such as the solution in which the side wall of the high shear chamber 113 is designed to be lower, since there is no interference from the high shear chamber 113, the front end of the first hoop body segment 211 and the front end of the second hoop body segment 212 can also adopt the above-mentioned tightening method between the two rear ends, that is, the first approach plate structure 2111 and the third approach plate structure 2121 are directly connected and tightened by a bolt 221 and a nut 222.
