DETAILED DESCRIPTION

[0034] like Figure 1-5 As shown, an automatic sludge feeding device includes a biochemical pool 1 and a sewage pipe 3 arranged at one end of the biochemical pool 1. The sewage pipe 3 passes through the biochemical pool 1 and is fixedly matched therewith. In actual use, the sewage pipe 3 is connected to an external sludge pump, so that the sludge in the sludge pool can be introduced into the biochemical pool 1 through the sewage pipe 3.

[0035] In order to evenly add the sludge into the biochemical pool 1, the present solution provides two sludge boxes 5 for containing sludge at one end of the biochemical pool 1 close to the sewage pipe 3. The top surface of the sludge box 5 is an open structure, and the bottom surface of the sludge box 5 is provided with a through groove 501. In actual use, a sealing plate 9 for sealing the through groove 501 is elastically installed at the inner bottom end of the sludge box 5. The sealing plate 9 is provided with a strip-shaped sludge guide groove 901. When the sludge guide groove 901 is aligned with the through groove 501, the sludge in the sludge box 5 can be discharged into the biochemical pool 1.

[0036] Connecting columns 4 are provided at both ends of the sludge box 5. The sludge box 5 can move in the vertical direction relative to the connecting columns 4, and the sludge box 5 and the connecting columns 4 are elastically matched. The connecting columns 4 and the sludge box 5 are connected by a limiting component. A crossbeam 6 matched with the connecting columns 4 is slidably installed on the top of the biochemical pool 1. Specifically, the connecting column 4 is semi-cylindrical, and the connecting column 4 and the crossbeam 6 are mutually clamped, and the connecting column 4 can rotate relative to the crossbeam 6.

[0037] In actual use, when the crossbeam 6 drives one of the sludge boxes 5 to move to the top of the sludge box 5 near the sewage pipe 3 of the biochemical pool 1 and aligns with it, the connecting columns 4 at the ends of the two sludge boxes 5 can fit together and form a cylindrical structure. At this time, the two connecting columns 4 that fit together are driven to rotate, so that the connecting column 4 that cooperates with the lower sludge box 5 can rotate to the side away from the sewage pipe 3, and the crossbeam 6 can drive the lower sludge box 5 to move in the process of moving away from the sewage pipe 3. Through this structure, the sludge in the sludge box 5 can be continuously put into the biochemical pool 1, thereby making the overall operation more consistent.

[0038] like Figure 2-11 As shown, the above-mentioned limit assembly includes a slide bar 13 that slidably cooperates with the connecting column 4. Specifically, the slide bar 13 is elastically cooperated with the connecting column 4, and the slide bar 13 can move in the vertical direction relative to the connecting column 4. Limit blocks 14 are elastically installed at both ends of the slide bar 13, and two limit grooves 502 that cooperate with the limit blocks 14 are provided on the end surface of the sludge box 5. When the limit block 14 is in a pop-up state and inserted into the limit groove 502, the sludge box 5 is connected to the connecting column 4.

[0039] Further, refer to Figure 9-11 As shown, a notch 1301 is provided on one side surface of the slide bar 13, and a limiting column 17 matching the notch 1301 is elastically mounted on the connecting column 4. When the two sludge boxes 5 are aligned in the vertical direction, the two connecting columns 4 can fit each other. During this process, the limiting columns 17 on the two connecting columns 4 can be pressed against each other, so that one end of the limiting column 17 is inserted into the notch 1301, thereby locking the slide bar 13 and the connecting column 4.

[0040] An electromagnet 19 is fixedly embedded in the slide bar 13, and a pull plate 20 is set at both ends of the electromagnet 19. The pull plate 20 is made of iron. The pull plate 20 slides with the slide bar 13, and a pull rope 21 is fixed between the pull plate 20 and the limit block 14. The pull rope 21 passes through the slide bar 13 and slides with it. When the two connecting columns 4 are in contact with each other, the electromagnet 19 can be in an energized state, so that the suction force of the electromagnet 19 on the pull plate 20 can pull the pull rope 21, so that one end of the limit block 14 moves out of the limit groove 502, so that the slide bar 13 and the sludge box 5 are disconnected. At this time, the connecting column 4 can rotate relative to the sludge box 5.

[0041] In order to realize the connection between the connecting column 4 and the cross beam 6, the present solution is fixedly provided with a semi-circular upper joint 401 at the top end face of the connecting column 4, and a plug hole 4011 is provided at the top end face of the upper joint 401. The bottom surface of the cross beam 6 and the positions near both ends are provided with a slide groove that slides with the upper joint 401. The slide groove is also semi-circular, and the top wall of the inner cavity of the slide groove is elastically installed with a plug block 15 that matches the plug hole 4011. The plug block 15 is cylindrical as a whole. Figure 8 As shown, the outer peripheral surface of the plug-in block 15 is arranged as a conical surface near the bottom end, the cross-sections of the upper joint 401 and the slide groove are both T-shaped, and the two ends of the slide groove extend to the side of the beam 6.

[0042] A slide 8 is provided below the connecting column 4, and a slide 8 near the sewage pipe 3 is fixedly connected to the biochemical pool 1, referring to Figure 3-Figure 4 , Fig. 9 As shown, a positioning rod 7 is fixedly arranged on a slide seat 8 fixed to the biochemical pool 1, and the positioning rod 7 passes through another slide seat 8 and slides with it, so that when the crossbeam 6 drives the sludge box 5 to approach the sewage pipe 3, the positioning rod 7 can pass through the moving slide seat 8;

[0043] Further, a lower joint 402 is fixedly provided at the bottom end surface of the connecting column 4, and the lower joint 402 is rotatably matched with the slide seat 8. The slide seat 8 is elastically mounted with a protrusion 18, and a groove matching with the protrusion 18 is provided on the bottom end surface of the lower joint 402. Fig.10 As shown, the protrusion 18 is also in a cylindrical structure as a whole, and the outer side of one end of the protrusion 18 close to the lower joint 402 is set as a conical surface.

[0044] In actual use, the movement of the crossbeam 6 can drive the sludge box 5 to move in the biochemical pool 1, so that the sludge in the sludge box 5 is put into the biochemical pool 1. As the amount of sludge in the sludge box 5 gradually decreases, the overall weight of the sludge box 5 will also decrease accordingly. At this time, the sludge box 5 can gradually bounce upward relative to the connecting column 4. When the sludge box 5 completes a stroke and gradually returns to the sewage pipe 3, the sludge in the sludge box 5 is completely discharged and the sludge box 5 also moves to the top limit position relative to the connecting column 4. At the same time, a sludge box 5 located at the end of the biochemical pool 1 is in a state of loading sludge. During this process, the weight of the sludge box 5 gradually increases, so that the sludge box 5 can gradually move downward. When the sludge box 5 at the end of the biochemical pool 1 moves downward to the limit position, the two sludge boxes 5 are just staggered in the vertical direction, so that the crossbeam 6 can drive the sludge box 5 below it to move above the other sludge box 5. When the two sludge boxes 5 are aligned in the vertical direction, the connecting columns 4 at the ends of the two sludge boxes 5 can fit each other. During this process, the slide seat 8 under the crossbeam 6 can be inserted into the positioning rod 7. As the two connecting columns 4 gradually approach each other, the limit column 17 on the connecting column 4 is squeezed and moved toward the approaching The slide bar 13 moves in the direction of the slide bar 13. In actual application, when the sludge box 5 at the end of the biochemical pool 1 moves downward to the limit position, the slide bar 13 at the end of the sludge box 5 can be aligned with the limit column 17 on the connecting column 4. Therefore, when the limit column 17 is squeezed, one end of the limit column 17 can be inserted into the notch 1301 on the slide bar 13, so that the slide bar 13 and the connecting column 4 are clamped. At the same time, when the two connecting columns 4 are close to each other, the electromagnet 19 on the slide bar 13 can be in an energized state, and the suction force of the electromagnet 19 on the pull plate 20 can tighten the pull rope 21, so that the limit block 1 4 is moved out of the limiting groove 502, so that the slide bar 13 and the sludge box 5 are disconnected. At this point, the slide bar 13 and the connecting column 4 are locked with each other and are disconnected from the sludge box 5. In actual use, the support plate 23 can be fixedly installed at one end of the biochemical pool 1 near the sewage pipe 3. When the sludge box 5 at one end of the biochemical pool 1 moves downward to the limit position, it can fall onto the support plate 23. The sludge box 5 can be stably supported by the support plate 23. Therefore, when the upper sludge box 5 is disconnected from the slide bar 13, the sludge box 5 at the upper side can stably fall onto the sludge box 5 at the lower side.

[0045] When the two sludge boxes 5 are aligned in the vertical direction, since the two connecting columns 4 are fitted in a cylindrical shape, they can drive the two connecting columns 4 that are fitted to each other to rotate. Since the outer bottom end of the plug-in block 15 is a conical surface, when the pressure between the plug-in block 15 and the socket 4011 increases, the plug-in block 15 can be guided out of the socket 4011. When the two connecting columns 4 are rotated 180°, the connecting column 4 originally placed at the end of the biochemical pool 1 is rotated to the side away from the sewage pipe 3 and connected to the crossbeam 6, and the connecting column 4 originally matched with the crossbeam 6 is rotated to the side close to the sewage pipe 3. When the connecting column 4 is rotated 180°, the plug-in block 15 on the crossbeam 6 can be inserted into the socket 4011 at the upper joint 401, and the protrusion 18 on the slide seat 8 can be inserted into the groove, so that the connecting column 4 can be stably placed between the crossbeam 6 and the slide seat 8 after rotating 180°;

[0046] In addition, when the cross beam 6 moves in a direction away from the sewage pipe 3, the two connecting columns 4 will gradually move away from each other. During this process, the electromagnet 19 is in a de-energized state, so that the limit block 14 can pop up again, so that as the connecting column 4 rotates to the slide bar 13 below the cross beam 6, it can be aligned with another limit groove 502 on the lower sludge box 5. When the limit block 14 pops up, the connecting column 4 below the cross beam 6 can be connected to the lower sludge box 5, and as the two connecting columns 4 gradually separate, the limit column 17 will gradually reset, so that the slide bar 13 and the connecting column 4 can be aligned with each other. The columns 4 are disengaged, and then, when the cross beam 6 moves in the direction away from the sewage pipe 3, it can drive the sludge box 5 below to move along the biochemical pool 1 in the direction away from the sewage pipe 3. Similarly, in the process of the cross beam 6 driving the sludge box 5 to move, the sludge in the sludge box 5 will be gradually discharged, so that the sludge box 5 can bounce upward relative to the connecting column 4, and the sludge box 5 located at the sewage pipe 3 can move downward during the process of loading the sludge, so that the two sludge boxes 5 can be staggered again in the vertical direction, which is conducive to the next exchange of the positions of the two sludge boxes 5.

[0047] In actual application, when the cross beam 6 drives the sludge box 5 to move to the sewage pipe 3, the sealing plate 9 on the sludge box 5 will contact the inner end surface of the biochemical pool 1, thereby driving the sealing plate 9 to move relative to the sludge box 5, so that the mud guide groove 901 and the through groove 501 are staggered to facilitate the loading of sludge through the sludge box 5.

[0048] In summary, this device sets the connecting column 4 at the end of the sludge box 5 into a semi-cylindrical shape. When the two sludge boxes 5 are aligned in the vertical direction, the two connecting columns 4 can fit together and form a cylindrical structure. At this time, the two connecting columns 4 that fit together can be driven to rotate, so that the connecting column 4 originally placed on the inner side rotates to the bottom of the beam 6 and is connected to the beam 6. When the beam 6 moves again, the sludge box 5 below and loaded with sludge can be driven by the beam 6 to move along the biochemical pool 1, so that the sludge in the sludge box 5 is discharged into the biochemical pool 1. When one of the sludge boxes 5 is in the process of discharging sludge into the biochemical pool 1, the other sludge box 5 is in a state of loading sludge, which makes the overall operation more coherent.

[0049] like Figure 1-9 As shown in 12-13, a through installation groove is opened on the connecting column 4 along its height direction, and the above-mentioned slide bar 13 is slidably set in the installation groove, and a vertical rod is fixedly set in the installation groove, the vertical rod passes through the slide bar 13 and slides with it, and a limit spring is sleeved on the outer side of the vertical rod, and the limit spring is located between the bottom end face of the slide bar 13 and the inner bottom face of the installation groove. Through this structure, elastic cooperation between the slide bar 13 and the connecting column 4 can be achieved. Specifically, when the sludge box 5 under the cross beam 6 gradually discharges the sludge, the sludge box 5 can be driven to move upward by the limit spring. In the process of the sludge box 5 at the sewage pipe 3 loading sludge, the sludge box 5 drives the slide bar 13 to compress the limit spring.

[0050] In order to drive the crossbeam 6 to move, in this solution, sliders 601 are fixedly provided at both ends of the crossbeam 6. The sliders 601 are slidably provided on the top of the biochemical pool 1, and a motor is fixedly installed on the slider 601. The output end of the motor is connected to a driving gear 12. A rack 2 meshing with the driving gear 12 is fixedly provided on the biochemical pool 1. Through this structure, when the motor rotates forward and reversely, the crossbeam 6 can move forward and reversely. In actual use, travel switches can be installed on both sides of the slider 601, and positioning blocks matching the travel switches are provided at both ends of the biochemical pool 1. Specifically, a time relay can be connected between the travel switch and the motor. The motor can be controlled through this structure. Of course, the motor can also be controlled in a programming manner so that the motor can drive the crossbeam 6 to move back and forth.

[0051] In order to drive the connecting column 4 to rotate, a semi-cylindrical half gear 11 can be fixedly set at the outer bottom end of the connecting column 4, and a main gear 10 meshing with the half gear 11 is provided in the biochemical pool 1. A driving motor for driving the main gear 10 to rotate is installed in the biochemical pool 1. When the two connecting columns 4 are fitted together, the two half gears 11 can be combined into a complete gear structure. At this time, the connecting column 4 can be driven to rotate through the meshing of the main gear 10 and the half gear 11.

[0053] The slide bar 13 is provided with a storage groove for installing the pull plate 20 and the electromagnet 19. The electromagnet 19 is fixedly arranged in the storage groove, and the pull plate 20 is slidably arranged in the storage groove. The end of the slide bar 13 is provided with a rectangular groove that slidably cooperates with the limit block 14, and a first spring is fixedly arranged between the inner end surface of the rectangular groove and the limit block 14.

[0054] Cross bars 22 are fixedly provided on both sides of the interior of the sludge box 5, and a circular hole is opened on the sealing plate 9 to slide with the cross bar 22, and a second spring is fixedly provided between the inner end surface of the circular hole and the cross bar 22, and the sealing plate 9 passes through the sludge box 5 and slides with it; of course, during specific use, a valve can also be installed at the bottom of the sludge box 5, and the staff can control the opening of the valve to discharge the sludge in the sludge box 5.

[0055] A cross groove is provided on the connecting column 4, and the two ends of the cross groove extend to the outer side surface of the connecting column 4 and the inner wall of the installation groove respectively. A guide block slidingly matched with the cross groove is fixedly provided on the limiting column 17, and a second spring is fixedly provided between the guide block and the inner end surface of the cross groove to achieve elastic cooperation between the limiting column 17 and the connecting column 4. In actual use, a positioning column can also be fixedly installed on the bottom surface of the installation groove, and the sludge box 5 can contact the positioning column when it moves downward to the extreme position.

[0056] In actual use, a detection unit 16 is fixedly installed on one side of the connecting column 4 where the limiting column 17 is installed.
