Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a slag discharge and conveying device. Background Art

[0002] Super magnetic separation equipment is a commonly used water treatment equipment, which achieves physical separation by providing magnetic field suction through magnetic steel. With the help of external magnetic field, the suspended solids in the wastewater with magnetic properties are separated to achieve the purpose of purifying water. Compared with traditional methods such as sedimentation or filtration, magnetic separation has stronger processing capacity, higher efficiency, less energy consumption and more compact equipment.

[0003] The main super magnetic separation equipment on the market includes magnetic disk liquid separation and purification equipment, which removes magnetic suspended solids in the wastewater by rotating the magnetic disk in the wastewater. Correspondingly, a scraping device needs to be set up to scrape off the magnetic slag adsorbed on the disk. As previously applied by the applicant, patent number: CN202122624712.9, patent name: A scraping and conveying device, which scrapes off the suspended solids in the middle of the disk with a scraping bar and then sends it into an auger. After the solids are sent out of the super magnetic separation equipment by the auger, they are sent to the next process. However, this structure still has the following shortcomings:

[0004] 1. A slag outlet is set at the bottom of the auger end. During super magnetic separation, the water content of the solids is different. If the water content is high, the solids can be smoothly sent out from the slag outlet. If the water content is low, the solids are easily blocked at the slag outlet, resulting in unsmooth slag discharge and the need for manual cleaning.

[0005] 2. The slag outlet is located outside the super magnetic separation device. The slag outlet 101 is directly above the opening structure. The end of the auger 102 (the part shown in the figure) is below the opening. A U-shaped cover plate 103 is directly used to cover the opening to block it. Figure 1 As shown in the figure, the main function of the cover is to facilitate opening and quick cleaning if there is a blockage. However, during the rotation of the auger, solid objects containing water will be thrown onto the top surface of the cover. Over time, the fixed objects will move to both sides and overflow from the connection between the cover and the opening and drip onto the ground, causing environmental damage and affecting the cleanliness of the workshop.

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0034] Example 1: See Figures 2 to 6 As shown, a slag discharge conveying device comprises a casing 1 and a screw conveying shaft 2, a shell 3 is installed on the right outer wall of the casing 1, a conveying trough 4 connected to the top of the casing 3 is arranged in the casing 3, and the left end of the conveying trough 4 is connected to the inside of the casing 1; the left end of the screw conveying shaft 2 is rotatably installed in the casing 1, the right end of the screw conveying shaft 2 passes through the casing and is arranged in the casing 3, a discharge port 5 is arranged at the bottom of the casing 3, a discharge pipe 6 is arranged obliquely toward the lower right side at the bottom of the discharge port 5, and an upper cover 7 is detachably installed on the top of the casing 3, and the upper cover 7 covers the conveying trough 4;

[0035] A flushing pipe 8 is further inserted into the shell 3 , and the flushing pipe 8 is arranged above the right side of the discharge port 5 . At least one flushing port 9 is provided on the lower outer surface of the flushing pipe 8 , and the flushing port 9 is arranged toward the discharge port 5 .

[0036] In this embodiment, the bottom of the conveying trough 4 is an arc-shaped surface, and the arc-shaped surface is arranged close to the lower outer surface of the screw conveying shaft. The front inner wall and the rear inner wall of the conveying trough are arranged close to the screw conveying trough. An arc-shaped support plate 10 is also arranged in the casing 1. The arc-shaped support plate 10 is located below the screw conveying shaft 2, and the inner wall of the arc-shaped support plate 10 is arranged close to the lower outer surface of the screw conveying shaft. The top surface of the arc-shaped support plate is flush with the arc-shaped surface. The left end of the arc-shaped support plate is connected to the left inner wall of the casing, the right side of the arc-shaped support plate is connected to the left side of the casing, and the arc-shaped support plate is connected to the left side of the casing. The top surface of the right end of the support plate is connected to the arc surface. The housing 1 is provided with a disk group 11, a scraper bar assembly 12 and a slag planing bar assembly 13. The disk group is arranged at the front side of the spiral conveying shaft. At the same time, a baffle 14 is arranged at the top of the rear end of the arc support plate. The front end of the scraper bar assembly is inserted into the disk group and contacts the side wall of the adjacent disk in the disk group. The rear end of the scraper bar assembly is connected to the top of the front end of the arc support plate. The disk group is used to adsorb the magnetic slag adsorbed in the sewage, and the scraper bar is used to scrape off the magnetic slag adsorbed by it. The slag planing bar assembly is rotatably arranged above the scraper bar assembly, and is used to scrape the slag scraped from the scraper bar assembly onto the arc support plate. In this way, when the spiral conveying shaft rotates, the slag on the arc support plate is transported to the conveying trough of the housing toward the discharge port through the spiral conveying shaft. When the slag is transported to the discharge port, the slag falls from the discharge port into the discharge pipe, and the slag is transported to the next process through the discharge pipe. Among them, since the water content in the slag is different at different times, if the water content is a little more, the slag can be discharged smoothly from the discharge port, and the discharge pipe can also smoothly discharge the slag containing water. If the water content in the slag is relatively low, the slag is easy to be blocked at the discharge port, or the slag is blocked in the discharge pipe, so that the discharge port is also blocked, resulting in the slag being able to only push the upper cover open and fall out from the top of the shell. Therefore, in this embodiment, by arranging a flushing pipe in the shell and arranging a flushing port below the flushing pipe, the end of the flushing pipe will be connected to the water source, and water will be sent into the shell through the flushing port. At the same time, since the flushing port is facing the discharge port, the slag can be flushed and replenished with water, which can effectively prevent the blockage of the discharge port and the discharge pipe, and ensure the stability and smoothness of slag discharge.

[0037] At the same time, by adjusting the water supply pressure, the flushing force of the slag can be adjusted to effectively prevent the occurrence of blockage. Among them, the shell is a top-opening structure, so that the discharge port can leak out. When the flushing pipe is in the flushing state, there is still blockage. In this way, the slag can directly push open the upper cover and leak out from the top of the conveying trough. The staff can find it at the first time and clean it. If there is still a blockage, but the blockage is not very serious, when it is found that the slag cannot be normally delivered to the next process, the staff can open the upper cover, so that they can observe the situation in the conveying trough most intuitively, and can also view part of the internal situation of the casing through the conveying trough, so that the staff can arrange their work. At the same time, since the spiral conveyor shaft may throw up slag and water when it rotates, the slag and water will be thrown out from the top of the placement trough, affecting the cleanliness of the workshop, which is not environmentally friendly. In order to prevent external debris or the staff's hands from accidentally reaching into the interior and posing a safety hazard, the upper cover is directly detachably installed on the shell through the setting of the upper cover to cover the conveying trough to prevent the slag and water from being thrown out. It is also safer and more beautiful.

[0038] See also Figures 4 to 6 As shown, the bottom sides of the upper cover 7 are provided with clamping parts respectively, and the bottom of each clamping part is provided with a clamping slot 15 respectively, and the front side wall and the rear side wall of the shell 3 are respectively inserted into a clamping slot 15.

[0039] The clamping member includes an inner plate 16 and an outer plate 17 which are parallel to each other. The inner plate 16 , the outer plate 17 and the upper cover 7 form the clamping slot 15 . The inner plate 16 is inserted into the conveying slot 4 , and the outer plate 17 is arranged outside the shell 3 .

[0040] In the previous structure, only outer plates are set on both sides of the bottom of the upper cover, and the outer plates are on the outside of the shell. During the rotation of the spiral conveyor shaft and the conveying of slag, the slag and water will be thrown onto the top surface of the upper cover, and the slag and water will run to both sides. There will be some micro gaps between the outer plates and the shell, and the slag and water will leak out from between the outer plates and the shell to the outside of the shell, resulting in poor cleanliness of the workshop and environmental protection. Therefore, in this embodiment, an inner plate is also set on the basis of the outer plate, so that the slag and water thrown onto the upper cover will be blocked by the inner plate when flowing toward both sides and flow downward back into the conveying trough, effectively preventing the leakage of slag and water. In addition, it will not affect the rapid disassembly and installation of the upper cover.

[0041] In order to further prevent the leakage of slag and water, the height of the inner plate is greater than that of the outer plate. The outer plate mainly plays a limiting role to prevent the upper cover from falling. If the height of the inner plate is higher, the bottom of the inner plate will be closer to the bottom of the conveying trough, which will have a better blocking effect on slag and water. In addition, when the slag and water are thrown out during the rotation of the spiral conveying shaft, their sides are thrown on the inner plate as much as possible to prevent leakage from the connection between the side wall of the conveying trough and the upper cover.

[0042] At the same time, due to the existence of the flushing pipe, in order to prevent the flushing pipe from affecting the installation of the upper cover, a groove is provided at the bottom of the inner side plate for giving way to the flushing pipe, and the bottom of the groove is against the upper outer surface of the flushing pipe. Moreover, the slag and water at the groove will be blocked by the flushing pipe, so the existence of the inner side plate can effectively ensure the blocking and leak-proof effects.

[0043] The side walls of the inner plate and the outer plate are in contact with the outer wall and the inner wall of the shell respectively, so as to ensure the anti-leakage effect as much as possible.

[0044] See also Figure 2 , 4 As shown, the right end of the spiral conveying shaft 2 is rotationally connected to the right end of the shell 3, and the left end of the spiral conveying shaft 2 is rotationally connected to the casing 1; wherein, the right end of the shell is a vertical plate, the right end of the spiral conveying shaft is rotationally connected to the vertical plate, and the right side surface of the upper cover is in contact with the left side surface of the vertical plate.

[0045] The outer surface of the bottom of the screw conveyor shaft is arranged close to the bottom surface of the conveying trough. In this way, the screw conveyor shaft will push the slag to move from left to right, from the housing to the conveying trough, and be discharged from the discharge port during rotation.

[0046] See also Figure 4 As shown, the flushing pipe 8 is arranged between the upper cover and the screw conveying shaft 2. The flushing pipe is arranged above the screw conveying shaft to prevent the slag from blocking and clogging the flushing pipe as much as possible.

[0047] Furthermore, in order to facilitate the arrangement of the flushing pipe, the flushing pipe is arranged perpendicular to the spiral conveying shaft.

[0048] See also Figure 4 , 5As described, a mounting hole 18 is provided on the side wall of the housing 3, and the flushing pipe 8 passes through the mounting hole 18 and is inserted into the conveying trough 4, and the connection between the flushing pipe 8 and the mounting hole 18 is sealed. The mounting hole is used for the installation of the flushing pipe and the housing, so that the flushing pipe can be inserted into the housing, and it is convenient to seal the flushing pipe and the mounting hole. Furthermore, there are two mounting holes, which are respectively arranged on the front and rear sides of the housing, and the two ends of the flushing pipe are respectively inserted into one mounting hole, so that the flushing pipe does not need to be suspended in the air, and both ends have support, which ensures the stability and life of the flushing pipe.

[0049] See also Figure 4 As shown, the spiral conveying shaft 2 includes a connecting shaft 19 and a spiral blade 20 arranged on the outer surface of the connecting shaft 19, the left end of the connecting shaft 19 is rotatably connected to the casing 1, the right side of the connecting shaft 19 is rotatably connected to the right end of the shell 3, and the right end of the spiral blade 20 is arranged directly above the discharge port 5.

[0050] After the slag enters the arc-shaped support plate, a driving mechanism is provided outside the casing to drive the connecting shaft to rotate. When the connecting shaft rotates, the spiral blades on its outer surface are also driven to rotate. When the spiral blades rotate, the spiral blades push the slag toward the discharge port and are discharged from the discharge port, thereby realizing the discharge of the slag.

[0051] See also Figure 4 As shown, an annular plate 21 is further provided on the outer surface of the connecting shaft 19 at the right end of the spiral blade 20, and the annular plate 21 is arranged directly above the discharge port 5, and the annular plate 21 is arranged close to the right side of the discharge port 5; wherein, there is a spacing between the annular plate and the free end of the spiral blade, and when the spiral blade pushes the slag to move to the right, when the slag is sent to the rightmost end of the spiral blade, part of the slag may move to the right and fall into the discharge port, and move to the right side of the discharge port. Therefore, by setting the annular plate, the slag is restricted by the annular plate, so that after the slag is sent to the rightmost end of the spiral blade, it will be blocked by the annular plate, so that the slag will fall into the discharge port, thereby ensuring the stability and quality of slag discharge.

[0052] The flushing pipe is arranged above the connecting shaft on the right side of the annular plate. In this way, there is no spiral blade to block the flushing pipe, which will not occupy too much height space and will not affect the use of the upper cover. At the same time, the flushing port is arranged toward the discharge port, and the water flushed out of the flushing port will be flushed between the annular plate and the bottom surface of the conveying trough, facing the flushing port.
