Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage electromagnetic cracker. Background Art

[0002] Poultry and livestock farming provides humans with a large amount of meat products every year, meeting the public's demand for meat and egg products, but at the same time, it also produces a large amount of wastewater. This wastewater mainly includes urine excreted by poultry and livestock, clean flushing water from pens, feeding troughs, floors and equipment, and a small amount of wastewater generated during the workers' living and production processes.

[0003] The livestock and poultry industry generates a huge amount of sewage every year, and there are various ways to treat sewage. At present, most livestock and poultry sewage is treated by separating the solids in the sewage and drying them, and then burying or otherwise treating the dried materials. The whole process is time-consuming and labor-intensive, and the treatment effect is low. Therefore, we propose a sewage electromagnetic cracker. Summary of the invention

[0004] The purpose of the present invention is to provide a sewage electromagnetic cracker with high treatment efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a sewage electromagnetic cracker, comprising a cache box, an electromagnetic cracking component, a cooling cover, a mounting frame, a water pump, an inlet pipe connected to the cache box, a connecting pipe 1 connecting the cache box and the electromagnetic cracking component, a connecting pipe 2 connecting the electromagnetic cracking component and the cooling cover, an exhaust pipe connected to the cooling cover, and a support column installed on the cooling cover, the inner side of the mounting frame is rotatably connected with a heat recovery barrel passing through the cooling cover, the heat recovery barrel is connected with a liquid inlet pipe, the water inlet end of the water pump is connected with a recovery pipe connected to the heat recovery barrel, the recovery pipe is rotatably connected to the inner wall of the heat recovery barrel, the water outlet end of the water pump is connected to the cache box through a pipeline, an anti-precipitation component is installed inside the heat recovery barrel, a drive component with one end extending into the interior of the heat recovery barrel and driving the anti-precipitation component to rotate is installed on the heat recovery barrel, an arc plate is installed on the cooling cover, and a gear ring 1 meshing with the drive component is installed on the inner side of the arc plate.

[0006] By adopting the above technical solution, the sewage enters the interior of the cache box through the inlet pipe, is temporarily stored in the cache box, and then enters the interior of the electromagnetic cracking component through the connecting pipe for heating and decomposition, thereby realizing rapid treatment of the sewage with high treatment efficiency;

[0007] The split gas enters the cooling hood through the connecting pipe 2, and the gas temperature is lowered to meet the requirements of high-altitude discharge inside the cooling hood before being discharged through the exhaust pipe. The wastewater to be treated is injected into the heat recovery barrel through the liquid inlet pipe to absorb the heat in the cooling hood, and then is pumped to the temporary storage box for temporary storage. While accelerating the cooling of the gas, the wastewater can be preheated, thereby improving the efficiency of the next thermal decomposition and further improving the wastewater treatment efficiency.

[0008] When preheating the sewage to be treated, the sewage will always sink in the lower half of the heat recovery barrel, causing the heat absorbed by the upper half of the heat recovery barrel to directly heat the sewage. The driving component rotates and meshes with the gear ring 1, so that the driving component moves in a circle around the gear ring 1, and then the heat recovery barrel rotates inside the cooling cover, so that the entire barrel body of the heat recovery barrel can preheat the sewage to be treated in the barrel body, thereby improving the preheating efficiency of the sewage.

[0009] When the heat recovery barrel rotates to preheat the sewage, the sewage will not rotate with the heat recovery barrel, but will remain in the lower half of the heat recovery barrel. In order to prevent impurities in the sewage from settling in the heat recovery barrel and causing blockage, the driving component rotates while also driving the anti-sedimentation component to rotate inside the heat recovery barrel, continuously scraping away impurities in the sewage to prevent impurity precipitation and cause blockage.

[0010] The present invention is further configured as follows: the electromagnetic cracking assembly includes an electromagnetic cracking box connected between the connecting pipe 1 and the connecting pipe 2, an electromagnetic coil installed on the outside of the electromagnetic cracking box, a partition 1 installed in the electromagnetic cracking box, a partition 2 installed in the electromagnetic cracking box and connected to the partition 1, and vents opened on the partition 1 and the partition 2, the partition 1 and the partition 2 divide the electromagnetic cracking box into a heating chamber 1 and a heating chamber 2, and the electromagnetic coil is electrically connected to an external controller.

[0011] By adopting the above technical scheme, part of the sewage in the cache box enters the electromagnetic cracking box through connecting pipe 1, and the controller controls the electromagnetic coil wrapped around the outside of the electromagnetic cracking box to heat it, providing high temperature to the box, first raising the temperature in heating chamber 1 to degrees Celsius, so that the sewage is vaporized into gas in heating chamber 1, and then enters heating chamber 2 from the vent hole on partition 1, raising the internal temperature of the heating chamber to degrees Celsius, which will completely crack the harmful substances in the vaporized sewage, and after completion, the harmless gas generated enters the cooling hood from connecting pipe 2, and the gas temperature inside the cooling hood is reduced to meet the requirements of high-altitude emission and then discharged through the exhaust pipe. The sewage is vaporized by heating with the electromagnetic coil and then further heated to crack the harmful substances in the gas, thereby realizing rapid treatment of sewage with high treatment efficiency.

[0012] The present invention is further configured as follows: the outer wall of the cooling cover is a heat insulating layer, the inner wall of the cooling cover is a heat conducting layer, and the inner wall of the cooling cover is smooth and fits with the outer wall of the heat recovery barrel.

[0013] By adopting the above technical solution, the outside is set as an insulation layer so that the heat inside the cooling cover will not be lost from the outside, and the inside is set as a heat conductive layer so that the heat in the cooling cover can be transferred to the heat recovery channel more quickly to preheat the sewage.

[0014] The present invention is further configured as follows: the bottom of the inner wall of the cache box is lower than the height of the inlet pipe and the connecting pipe.

[0015] By adopting the above technical solution, the sewage can achieve a caching effect in the cache box, preventing the sewage from continuously entering the electromagnetic cracking box and eventually filling it up or even damaging the electromagnetic cracking box due to water pressure.

[0016] The present invention is further configured as follows: a heat-insulating layer is installed outside the second connecting pipe.

[0017] By adopting the above technical solution, the insulation layer can reduce the heat loss of the hot air in the connecting pipe 2, and can better utilize the waste heat of the hot air to preheat the sewage, thereby improving the cracking efficiency of the sewage.

[0018] The present invention is further configured as follows: the anti-sedimentation component includes a gear ring 2 rotatably connected to the inner wall of the heat recovery barrel, a connecting shaft mounted on the gear ring 2 and rotatably connected to the inner wall of the heat recovery barrel, and a scraper mounted on the connecting shaft and in contact with the inner wall of the heat recovery barrel.

[0019] By adopting the above technical solution, the driving component engages with the second gear ring when rotating, so that the second gear ring rotates on the inner wall of the heat recovery barrel, thereby driving the scraper on the connecting shaft to continuously scrape the heat recovery barrel, thereby avoiding blockage caused by the precipitation of impurities in the sewage to be treated.

[0020] The present invention is further configured as follows: a sliding block is installed on the second gear ring, and an annular groove matching the sliding block is provided on the inner wall of the heat recovery barrel.

[0021] By adopting the above technical solution, the sliding of the slider in the annular groove allows the gear ring 2 to rotate on the inner wall of the heat recovery barrel, and the rotation stability of the gear ring 2 on the heat recovery barrel is also improved.

[0022] The present invention is further configured as follows: the driving assembly is rotatably connected to a rotating shaft on the heat recovery barrel, gear one and gear two are installed on the rotating shaft, a motor is installed on the heat recovery barrel, and a belt is transmission-connected between the rotating shaft and the motor output shaft.

[0023] The present invention is further configured as follows: the first gear meshes with the inner side of the first gear ring, and the second gear meshes with the inner side of the second gear ring.

[0024] By adopting the above technical solution, the motor starts and drives the rotating shaft to rotate through the batch, so that gear one and gear two on the rotating shaft rotate synchronously, gear one engages with gear ring one to make the heat recovery barrel rotate inside the cooling cover, so that the entire barrel body of the heat recovery barrel can preheat the sewage to be treated in the barrel body, thereby improving the preheating efficiency of the sewage, gear two engages with gear ring two to make gear ring two rotate, and then drives the scraper on the connecting shaft to continuously scrape the heat recovery barrel to avoid blockage caused by precipitation of impurities in the sewage to be treated.

[0025] The present invention is further configured as follows: the cooling cover is an annular cover, a plurality of ring-shaped and equidistantly distributed baffles are installed on the inner wall of the cooling cover, the baffles are spirally distributed on the inner wall of the cooling cover, and a spiral cooling channel is formed between two adjacent baffles.

[0026] By adopting the above technical solution, the spirally arranged baffle increases the flow path of the hot air inside the cooling hood, so that the heat recovery barrel can better absorb the heat in the cooling hood.

[0027] The beneficial effects of the present invention are:

[0028] 1. The sewage enters the cache box through the inlet pipe, is temporarily stored in the cache box, and then enters the electromagnetic cracking component through the connecting pipe for heating and decomposition, thereby achieving rapid treatment of the sewage with high treatment efficiency.

[0029] 2. The split gas enters the cooling hood through the connecting pipe 2. The gas temperature inside the cooling hood drops to a level that meets the requirements for high-altitude discharge and then is discharged through the exhaust pipe. The sewage to be treated is injected into the heat recovery barrel through the liquid inlet pipe to absorb the heat in the cooling hood. The sewage is then pumped to the temporary storage box for temporary storage. This can accelerate the cooling of the gas while preheating the sewage, thereby improving the efficiency of the next thermal decomposition and further improving the sewage treatment efficiency.

[0030] 3. When preheating the sewage to be treated, the sewage will always sink in the lower half of the heat recovery barrel, causing the heat adsorbed by the upper half of the heat recovery barrel to directly heat the sewage. The driving component rotates and engages with the gear ring 1, causing the driving component to make a circular motion around the gear ring 1, thereby causing the heat recovery barrel to rotate inside the cooling cover, so that the entire barrel body of the heat recovery barrel can preheat the sewage to be treated in the barrel body, thereby improving the preheating efficiency of the sewage.

[0031] 4. When the heat recovery barrel rotates to preheat the sewage, the sewage will not rotate with the heat recovery barrel, but will remain in the lower half of the heat recovery barrel. In order to prevent impurities in the sewage from settling in the heat recovery barrel and causing blockage, the driving component rotates while also driving the anti-sedimentation component to rotate inside the heat recovery barrel, continuously scraping away impurities in the sewage to prevent impurity precipitation and blockage.

DETAILED DESCRIPTION

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-6 The present invention provides a sewage electromagnetic cracker, comprising a cache box 1, an electromagnetic cracking component 2, a cooling cover 3, a mounting frame 5, a water pump 6, an inlet pipe 7 connected to the cache box 1, a connecting pipe 1 8 connecting the cache box 1 and the electromagnetic cracking component 2, a connecting pipe 2 9 connecting the electromagnetic cracking component 2 and the cooling cover 3, an exhaust pipe 10 connected to the cooling cover 3, and a support column 11 installed on the cooling cover 3, the inner side of the mounting frame 5 is rotatably connected to a heat recovery barrel 12 passing through the cooling cover 3, and the heat recovery barrel 12 is connected to a liquid inlet pipe 1 9. The water inlet end of the water pump 6 is connected with a recovery pipe 20 connected with the heat recovery barrel 12. The recovery pipe 14 is rotatably connected with the inner wall of the heat recovery barrel 12. The water outlet end of the water pump 6 is connected with the cache box 1 through a pipeline. An anti-precipitation component 13 is installed inside the heat recovery barrel 12. A driving component 14 is installed on the heat recovery barrel 12, one end of which extends into the interior and drives the anti-precipitation component 13 to rotate. An arc plate 15 is installed on the cooling cover 3. A gear ring 16 meshing with the driving component 14 is installed on the inner side of the arc plate 15.

[0042] The sewage enters the cache box 1 through the inlet pipe 7, is temporarily stored in the cache box 1, and then enters the electromagnetic cracking component 2 through the connecting pipe 8 to be heated and decomposed, thereby achieving rapid treatment of the sewage with high treatment efficiency.

[0043] The split gas enters the cooling hood 3 through the connecting pipe 2 9, and the gas temperature is reduced to meet the requirements of high-altitude discharge inside the cooling hood 3 before being discharged through the exhaust pipe 10. The sewage to be treated is injected into the heat recovery barrel 12 through the liquid inlet pipe 19, absorbs the heat in the cooling hood 3, and then is sent to the temporary storage box 1 for temporary storage through the water pump 6. While accelerating the cooling of the gas, the sewage can be preheated, thereby improving the efficiency of the next thermal decomposition and further improving the sewage treatment efficiency.

[0044] When the sewage to be treated is preheated, the sewage will always sink in the lower half of the heat recovery barrel 12, causing the heat adsorbed by the upper half of the heat recovery barrel 12 to directly heat the sewage, and the driving component 14 rotates and engages with the gear ring 16, so that the driving component 14 makes a circular motion around the gear ring 16, thereby causing the heat recovery barrel 12 to rotate inside the cooling cover 3, so that the entire barrel body of the heat recovery barrel 12 can preheat the sewage to be treated in the barrel body, thereby improving the preheating efficiency of the sewage.

[0045] When the heat recovery barrel 12 rotates to preheat the sewage, the sewage will not rotate with the heat recovery barrel 12, but will always remain in the lower half of the heat recovery barrel 12. In order to prevent impurities in the sewage from settling in the heat recovery barrel 12 and causing blockage, the driving component 14 rotates while also driving the anti-sedimentation component 13 to rotate inside the heat recovery barrel 12, continuously scraping off impurities in the sewage to prevent impurity precipitation and cause blockage.

[0046] The electromagnetic cracking assembly 2 includes an electromagnetic cracking box 21 connected between the connecting pipe 1 8 and the connecting pipe 2 9, an electromagnetic coil 22 installed on the outside of the electromagnetic cracking box 21, a partition 1 23 installed in the electromagnetic cracking box 21, a partition 24 installed in the electromagnetic cracking box 21 and connected to the partition 1 23, and a vent 25 opened on the partition 1 23 and the partition 2 24. The partition 1 23 and the partition 2 24 divide the electromagnetic cracking box 21 into a heating chamber 1 26 and a heating chamber 27. The electromagnetic coil 22 is electrically connected to an external controller. Part of the sewage in the cache box 1 enters the electromagnetic cracking box 21 through the connecting pipe 1 8. The controller controls the outside of the electromagnetic cracking box 21. The electromagnetic coil 22 wrapped around the inside is heated to provide high temperature in the box, first raising the temperature in the heating chamber 26 to 550 degrees Celsius, so that the sewage is vaporized into gas in the heating chamber 26, and then enters the heating chamber 27 from the vent hole 25 on the partition 23, and the internal temperature of the heating chamber 27 is raised to 760 degrees Celsius, which will completely decompose the harmful substances in the gasified sewage. After completion, the harmless gas generated enters the cooling cover 3 from the connecting pipe 29, and the gas temperature inside the cooling cover 3 is reduced to meet the requirements of high-altitude emission and then discharged through the exhaust pipe 10. The sewage is vaporized by heating with the electromagnetic coil 22 and then further heated to decompose the harmful substances in the gas, thereby realizing rapid treatment of the sewage with high treatment efficiency.

[0047] The outer wall of the cooling cover 3 is a heat insulating layer, and the inner wall of the cooling cover 3 is a heat conductive layer. The inner wall of the cooling cover 3 is designed to be smooth and fits with the outer wall of the heat recovery barrel 12. The outer part is set as a heat insulating layer so that the heat inside the cooling cover 3 will not be lost from the outside, and the inner part is set as a heat conductive layer so that the heat in the cooling cover 3 can be transferred to the heat recovery barrel 12 more quickly to preheat the sewage.

[0048] The bottom of the inner wall of the cache box 1 is lower than the height of the inlet pipe 7 and the connecting pipe 8, so that the sewage can achieve a cache effect in the cache box 1, avoiding the sewage from continuously entering the electromagnetic cracking box 21 and eventually filling it up or even damaging the electromagnetic cracking box 21 due to water pressure.

[0049] The outside of the connecting pipe 2 9 is provided with an insulation layer, which can reduce the heat loss of the hot air in the connecting pipe 2 9 , and can better utilize the waste heat of the hot air to preheat the sewage, thereby improving the cracking efficiency of the sewage.

[0050] The anti-precipitation component 13 includes a gear ring 131 rotatably connected to the inner wall of the heat recovery barrel 12, a connecting shaft 132 installed on the gear ring 131 and rotatably connected to the inner wall of the heat recovery barrel 12, and a scraper 133 installed on the connecting shaft 132 and in contact with the inner wall of the heat recovery barrel 12. When the driving component 14 rotates, it engages with the gear ring 131, so that the gear ring 131 rotates on the inner wall of the heat recovery barrel 12, thereby driving the scraper 133 on the connecting shaft 132 to continuously scrape the heat recovery barrel 12 to avoid blockage caused by precipitation of impurities in the sewage to be treated.

[0051] A slider 17 is installed on the gear ring 131, and an annular groove 18 adapted to the slider 17 is opened on the inner wall of the heat recovery barrel 12. The sliding of the slider 17 in the annular groove 18 allows the gear ring 131 to rotate on the inner wall of the heat recovery barrel 12, which also improves the stability of the gear ring 131 rotating on the heat recovery barrel 12.

[0052] The driving assembly 14 rotates the rotating shaft 141 connected to the heat recovery barrel 12, the gear 1 142 and the gear 2 143 installed on the rotating shaft 141, the motor 144 installed on the heat recovery barrel 12, and the belt 145 connecting the rotating shaft 141 and the output shaft of the motor 144, the gear 1 142 meshes with the inner side of the gear ring 1 16, the gear 2 143 meshes with the inner side of the gear ring 2 131, and by adopting the above technical solution, the motor 144 starts and drives the rotating shaft 141 to rotate through the gear 145. The gear 1 142 and the gear 2 143 on the rotating shaft 141 rotate synchronously, and the gear 1 142 meshes with the gear ring 1 16 to make the heat recovery barrel 12 rotate inside the cooling cover 3, so that the entire barrel body of the heat recovery barrel 12 can preheat the sewage to be treated in the barrel body, thereby improving the preheating efficiency of the sewage, and the gear 2 143 meshes with the gear ring 2 131 to make the gear ring 2 131 rotate, thereby driving the scraper 133 on the connecting shaft 132 to scrape the heat recovery barrel 12 continuously, thereby avoiding blockage caused by the precipitation of impurities in the sewage to be treated.

[0053] The cooling hood 3 is an annular hood, and a plurality of baffles 4 distributed in an annular shape and at equal distances are installed on the inner wall of the cooling hood 3. The baffles 4 are distributed in a spiral shape on the inner wall of the cooling hood 3, and a spiral cooling channel 21 is formed between two adjacent baffles 4. The spirally arranged baffles 4 increase the flow path of hot air inside the cooling hood 3, so that the heat recovery barrel 12 can better absorb the heat in the cooling hood 3.
