Description

Technical Field

[0001] The invention belongs to the field of sewage treatment, and in particular relates to an automatic debris salvaging device for sewage treatment. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] Sewage is often mixed with a large amount of debris. Therefore, during the sewage treatment process, the debris in the sewage needs to be processed first to prevent the debris mixed in the sewage from clogging the sewage treatment system pipes during the sewage treatment process. The traditional debris processing method is to use a manual handheld salvage net to salvage the debris mixed in the sewage in turn. However, this method is relatively labor-intensive and cannot salvage the debris in the sewage in one go, which greatly affects the efficiency of cleaning the debris in the sewage.

[0004] Therefore, we propose an automatic debris salvaging device for sewage treatment to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide an automatic debris salvaging device for sewage treatment in order to solve the above problems.

[0006] The top end face of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure.

[0007] In the above-mentioned automatic debris salvaging device for sewage treatment, the driving mechanism includes a worm, two worm wheels and a reduction motor. The worm is rotatably connected to the support frame, and one end of the worm is transmission-connected to the reduction motor. The two worm wheels are respectively sleeved on two threaded sleeves, and both worm wheels are engaged with the worm.

[0008] In the above-mentioned automatic salvaging device for debris used in sewage treatment, the clamping mechanism includes an electromagnetic block, a tension spring, a permanent magnet block and a clamping block. A cavity matching the clamping slot is provided on the inner wall of the slide cylinder. The electromagnetic block is embedded in the cavity, and the electromagnetic block is electrically connected to the trigger switch. The permanent magnet block is slidably connected in the cavity, and the permanent magnet block and the electromagnetic block are fixedly connected by multiple tension springs. The clamping block is fixedly connected to the permanent magnet block, and the tension spring is made of non-magnetic stainless steel.

[0009] In the above-mentioned automatic salvaging device for sewage treatment, the trigger switch includes a trigger cavity, a conductive block and a conductive sheet. The trigger cavity is opened on the inner top surface of the upper end of the slide cylinder, and the conductive sheet is embedded in the trigger cavity. The conductive block is fixed on the upper end side wall of the slide rod, and the conductive block corresponds to the trigger cavity. The conductive sheet is connected in series with the drive motor and the electromagnetic block.

[0010] In the above-mentioned automatic debris salvaging device for sewage treatment, the side walls of the receiving seat are inclined, a large bearing is sleeved in the receiving seat, and the salvage box is interference-fitted with the large bearing.

[0011] In the above-mentioned automatic debris salvaging device for sewage treatment, the lower end of the screw is fixedly connected to a pull rod, and the end of the pull rod away from the screw is fixedly connected to the receiving seat, and the pull rod and the screw are made by an integral molding process.

[0012] In the above-mentioned automatic debris salvaging device for sewage treatment, two support blocks are fixedly connected to the support frame, and the worm is rotatably connected to the support blocks.

[0013] In the above-mentioned automatic debris salvaging device for sewage treatment, a plurality of plug-ins are fixedly connected to the lower side wall of the receiving seat, and slots matching the plug-ins are provided in the salvage pool, and both the plug-ins and the slots are wedge-shaped.

[0014] In the above-mentioned automatic debris salvaging device for sewage treatment, a plurality of balls are rotatably connected to the periphery of the salvage box, and the balls are rollingly connected to the inner wall of the receiving seat.

[0015] In the above-mentioned automatic debris salvaging device for sewage treatment, a warning light is provided on the support frame, and the warning light is electrically connected to the trigger switch.

[0016] Compared with the existing technology, the advantages of an automatic debris salvaging device for sewage treatment are:

[0017] 1. Through the provided threaded sleeve and screw, the threaded sleeve can be regulated to rotate under the control of the driving mechanism, so that the screw drives the receiving seat to slide upward, so that the debris in the sewage received by the receiving seat can be salvaged to the port of the salvage pool at one time, avoiding the labor loss of manual salvage and greatly improving the salvage efficiency.

[0018] 2. The driving motor and the slide cooperate to rotate the designed salvage box. After the debris is salvaged, the driving motor controls the rotation of the salvage box. The debris in the salvage box can be quickly dehydrated under the action of centrifugal force, making it easier for workers to pick up the debris.

[0019] 3. Through the cooperation of the worm and the two worm wheels, the reduction motor can drive the two threaded sleeves to rotate synchronously, avoiding the additional cost of adding another driving device. Through the electromagnetic block, the electromagnetic block can be magnetized or demagnetized by turning the power on and off. In combination with the permanent magnet block and the tension spring, the card block can be quickly docked or separated with the corresponding card slot, so that the slide rod can be quickly locked to avoid the slide rod slipping when the slide cylinder rotates, and at the same time facilitate the rapid unlocking of the slide rod later.

[0020] 4. The conductive blocks and conductive sheets are arranged to cooperate with the rise of the receiving seat, so that the conductive blocks and conductive sheets can automatically dock when the receiving seat rises to the required height, thereby realizing the automatic closing of the trigger switch, and then the electromagnetic block is automatically energized and the drive motor is automatically started, which greatly improves the automation of the device and facilitates the use of the device.

[0021] 5. By tilting the side walls of the receiving seat, sewage and debris can be better directed into the salvage box. The large bearing can ensure the stability of the connection between the salvage box and the receiving seat and seal the gap between the two.

[0022] 6. The pull rod is set to prevent the screw from directly contacting the sewage and prevent the debris in the sewage from eroding the threads on the screw. The pull rod and the screw are made of an integrated process to ensure the stability of the overall structure between the pull rod and the screw.

[0023] 7. The support block can provide a stable support for the worm. The cooperation between the plug block and the slot can ensure the stability of the socket in the salvage pool. The wedge-shaped design of the plug block and the slot can improve the stability of the connection between the plug block and the slot. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] like Figure 1-8 As shown, an automatic salvaging device for wastewater treatment includes a salvage pool 1, in which a receiving seat 2 is sealed and slidably connected. A plurality of plug-in blocks 21 are fixedly connected to the lower side wall of the receiving seat 2, and a slot 22 is provided in the salvage pool 1 to cooperate with the plug-in block 21. Both the plug-in block 21 and the slot 22 are wedge-shaped. By cooperating with the provided plug-in block 21 and the slot 22, the stability of the receiving seat 2 in the salvage pool 1 can be ensured. The wedge-shaped design of the plug-in block 21 and the slot 22 can improve the stability of the docking between the plug-in block 21 and the slot 22.

[0035] A support shaft 3 is rotatably connected to the socket 2, and a salvage box 4 is fixedly connected to the upper end of the support shaft 3. A plurality of balls 23 are rotatably connected to the salvage box 4 around the periphery, and the balls 23 are rollingly connected to the inner wall of the socket 2. The arrangement of the balls 23 can improve the rotation stability of the salvage box 4. The side walls around the socket 2 are tilted, and a large bearing 18 is sleeved in the socket 2, and the salvage box 4 is interference fit with the large bearing 18. By tilting the side walls around the socket 2, sewage and debris can be better introduced into the salvage box 4. The large bearing 18 can not only ensure the stable docking of the salvage box 4 with the socket 2, but also seal the gap between the salvage box 4 and the socket 2.

[0036] A plurality of filter holes 5 are provided on the lower side wall of the salvage box 4, a filter screen 6 is embedded in the lower side wall of the receiving seat 2, and a support frame 7 is fixedly connected to the upper side wall of the salvage pool 1. Two threaded sleeves 8 are rotatably connected to the support frame 7, and a screw 9 is threadedly connected in the threaded sleeve 8, and the lower end of the screw 9 is fixedly connected to the receiving seat 2, and a pull rod 19 is fixedly connected to the lower end of the screw 9, and the end of the pull rod 19 away from the screw 9 is fixedly connected to the receiving seat 2, and the pull rod 19 and the screw 9 are made of an integral molding process. By setting the pull rod 19, the screw 9 can be prevented from directly contacting the sewage, and the debris in the sewage can be prevented from eroding the threads on the screw 9. The pull rod 19 and the screw 9 adopt an integrated process to ensure the stability of the overall structure between the pull rod 19 and the screw 9.

[0037] A driving mechanism 10 that cooperates with the two threaded sleeves 8 is provided on the support frame 7. The driving mechanism 10 includes a worm 101, two worm wheels 102 and a reduction motor 103. The worm 101 is rotatably connected to the support frame 7, and one end of the worm 101 is transmission-connected to the reduction motor 103. The two worm wheels 102 are respectively sleeved on the two threaded sleeves 8, and the two worm wheels 102 are engaged with the worm 101. Through the cooperation of the set worm 101 and the two worm wheels 102, the reduction motor 103 can drive the two threaded sleeves 8 to rotate synchronously, avoiding the increased cost of adding additional driving equipment.

[0038] Two support blocks 20 are fixedly connected to the support frame 7, and the worm 101 is rotatably connected to the support block 20. The setting of the support block 20 can provide stable support for the worm 101. A slide 11 is rotatably connected to the support frame 7, and one end of the slide 11 is transmission-connected to a drive motor 12. A slide rod 13 is slidably connected in the slide 11. Both side walls of the slide rod 13 are provided with a card slot 14, and a card connection mechanism 15 that cooperates with the card slot 14 is provided in the slide 11.

[0039] The clamping mechanism 15 includes an electromagnetic block 151, a tension spring 152, a permanent magnet block 153 and a clamping block 154. A cavity 17 that matches the clamping slot 14 is opened on the inner wall of the slide 11. The electromagnetic block 151 is embedded in the cavity 17, and the electromagnetic block 151 is electrically connected to the trigger switch 16. The permanent magnet block 153 is slidably connected to the cavity 17, and the permanent magnet block 153 and the electromagnetic block 151 are fixedly connected by multiple tension springs 152. The clamping block 154 is fixedly connected to the permanent magnet block 153. The tension spring 152 is made of non-magnetic stainless steel material. Through the set electromagnetic block 151, the electromagnetic block 151 can be magnetized or demagnetized by turning on and off the power to the electromagnetic block 151. In conjunction with the permanent magnet block 153 and the tension spring 152, the clamping block 154 can quickly dock or separate with the corresponding clamping slot 14, so that the slide bar 13 can be quickly locked and rotated in conjunction with the slide 11, and at the same time, it is convenient to quickly unlock the slide bar 13 later.

[0040] The non-magnetic stainless steel material can prevent the tension spring 152 from being affected by the magnetism of the permanent magnet block 153 and the electromagnetic block 151. A trigger switch 16 is provided between the slide 11 and the slide rod 13, and the trigger switch 16 is electrically connected to the drive motor 12 and the clamping mechanism 15. The trigger switch 16 includes a trigger cavity 161, a conductive block 162 and a conductive sheet 163. The trigger cavity 161 is opened on the inner top surface of the upper end of the slide 11, and the conductive sheet 163 is embedded in the trigger cavity 161. The conductive block 162 is fixed on the upper end side wall of the slide rod 13, and the conductive block 162 corresponds to the trigger cavity 161. The conductive sheet 163 is connected in series with the drive motor 12 and the electromagnetic block 151. The conductive block 162 and the conductive sheet 163 are arranged to cooperate with the rise of the receiving seat 2, so that the conductive block 162 and the conductive sheet 163 can automatically dock when the receiving seat 2 rises to the required height, thereby realizing the automatic closure of the trigger switch 16, and then the electromagnetic block 151 is automatically energized, and the drive motor 12 is automatically started, which greatly improves the automation of the device and facilitates the use of the device. A prompt light 24 is provided on the support frame 7, and the prompt light 24 is electrically connected to the trigger switch 16. The setting of the prompt light 24 can remind the staff that the debris has been salvaged when the receiving seat 2 rises to the required position, so that the staff can quickly turn off the reduction motor 103.

[0041] The operating principle of the present invention is now described as follows:

[0042] When it is necessary to salvage debris in sewage, first inject the sewage mixed with debris into the salvage pool 1. After the injection is completed, the sewage mixed with debris will be received by the salvage box 4. Then, the reduction motor 103 is started. The reduction motor 103 drives the worm 101 to rotate. Under the transmission of the two worm wheels 102, the worm 101 drives the two threaded sleeves 8 to rotate. During the rotation of the threaded sleeves 8, the screw 9 is driven to rise. The screw 9 pulls the receiving seat 2 to slide up through the pull rod 19. The receiving seat 2 drives the sewage through the salvage box 4. As the salvage box 4 rises, sewage will be filtered out through the filter holes 5 and the filter screen 6, separating the sewage from the debris. The debris will continue to be driven up by the salvage box 4. At the same time, the slide bar 13 will slide up in the slide tube 11. When the debris salvaged by the salvage box 4 rises to the end of the salvage pool 1, the conductive block 162 on the slide bar 13 will dock with the conductive sheet 163 in the trigger chamber 161, causing the trigger switch 16 to automatically close. At this time, the warning light 24, the electromagnetic block 151 and the drive motor 12 will be energized.

[0043] When the prompt light 24 is energized, a warning light will be emitted to remind the staff that the debris has been salvaged to the appropriate position. At this time, the staff can turn off the reduction motor 103, and the electromagnetic block 151 will generate magnetism after being energized. At this time, the electromagnetic block 151 will repel the permanent magnet block 153, and the permanent magnet block 153 will drive the clamping block 154 to slide close to the clamping slot 14 and stretch the tension spring 152 until the clamping block 154 clamps the clamping slot 14, so that the slide bar 13 is locked. The drive motor 12 is energized to drive the slide 11 to rotate. With the slide bar 13 locked, the slide 11 will drive the salvage box 4 to rotate through the slide bar 13. During the rotation of the salvage box 4, the debris received will be driven to rotate, so that the debris received can be quickly dehydrated during the rotation. When the dehydration of the debris is completed, the power is turned off, so that the drive motor 12 is powered off and stopped. Subsequently, the staff can concentrate on processing the salvaged debris.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
