Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a discharge bulldozer for a sand-water separator drying device. Background Art
[0002] In the daily operation of sewage treatment plants, sand-water separators and screens are generally installed in the pretreatment stage to remove various floating and suspended objects in the sewage. If not handled properly, it will cause load and impact on subsequent treatment structures.
[0003] The sand-water separator can effectively separate the sand and water in sewage, improve the effect of sewage treatment, and reduce damage to subsequent treatment equipment. The separated screenings sand is generally transported by a belt conveyor or a screw conveyor to the press and then sent to the trash can, and then collected by manual pushing and transported out for treatment. Since the screenings sand has a strong odor and contains oily substances, this method will cause a poor processing workshop environment and is time-consuming and labor-intensive.
[0004] In order to ensure the workshop environment for collecting and conveying screen sand and solve the problem of time-consuming and labor-intensive manual transportation, the pretreatment area of the sewage plant was deeply analyzed and studied. Finally, the original open sewage pretreatment area on the ground was transferred to an underground sealed space for treatment, and the vacuum adsorption principle was used to transport the screen sand and other garbage from various places to the ground layer through a closed pipeline for transportation. On this basis, the transformation of the ultra-clean space of the sewage plant pretreatment was completed. Since the screenings sand coming out of the sand-water separator has a strong odor and contains oily substances, it needs to be dried. However, some heavy sand particles and other materials in the screenings sand fall into the drying device during the drying process and are deposited at the bottom to form large sand lumps. This will cause the screenings sand to be heated unevenly, and large sand lumps will also cause subsequent transportation pipelines to be blocked. In addition, these stuck agglomerated materials are repeatedly heated by hot air, which will also pose a safety hazard. In addition, the sewage treated by the sand-water separator is not from a single source, and some sewage may contain flocculent substances, which will also bring safety hazards to the heating of the drying device. In addition, the pretreatment area of the sand-water separator is limited by the on-site space, has a relatively small volume, a small processing capacity, and a relatively slow processing speed. Therefore, it is necessary to modify the drying device to be able to evenly heat and dry the screenings sand, improve the drying efficiency, prevent the screenings sand from being blocked, and solve the problem of pipeline blockage during subsequent vacuum transportation.

DETAILED DESCRIPTION
[0023] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0024] The utility model is one of the important technologies in the reconstruction plan of the ultra-clean space of the sewage treatment plant pretreatment. During the drying process of the screen sand, the accumulated screen sand is flattened by physical means to avoid the screen sand from forming a cone-shaped accumulation along the discharge port, and the distribution gap between the screen sand is increased to make it evenly distributed, thereby preventing the screen sand from forming a cone-shaped accumulation at the discharge port and solving the problem of pipeline blockage in the subsequent vacuum transportation process.
[0025] Combination Figure 1As shown, the unloading pusher 20 for the sand-water separator drying device of the utility model comprises a fixing frame, a pusher cylinder 23, and a pusher plate 24. The unloading pusher 20 adopts a physical method, and utilizes the reciprocating motion of the pusher plate 24 to squeeze the screen sand, push the screen sand agglomerates with high water content falling into the drying device 10, increase the gap between the screen sand, and make it evenly distributed.
[0026] Combination Figure 1 , Figure 3 As shown, the fixing frame includes a second fixing box 22 fixed to the inclined side of the drying device 10 and a first fixing box 21 connected to the second fixing box 22; one end of the first fixing box 21 away from the second fixing box 22 is fixedly connected to the top of the drying device 10. The unloading pusher 20 is installed on the drying device through the fixing frame, and the first fixing box 21, the second fixing box 22 and the drying device are fixed by bolts; in a specific embodiment, the first fixing box 21 is connected to the top of the drying device 10 through a connecting piece.
[0027] Combination Figure 1 , Figure 3 As shown, the push cylinder 23 is installed on the first fixed box 21 , and the output end of the push cylinder 23 is connected to the push plate 24 .
[0028] Combination Figure 1 , Figure 2 , Figure 3 As shown, the push plate 24 is arranged below the feed port 12 of the drying device 10; the push plate 24 reciprocates along the fixed frame under the action of the push cylinder 23 to push the screen sand falling into the drying device 10 flat. The end of the push plate 24 is provided with a mounting hole 241 connected to the output end of the push cylinder 23, and the push plate 24 and the push cylinder 23 are connected and fixed by bolts. When the drying device 10 dries the screen sand, the screen sand falls along the feed port 12 onto the rake-tooth oscillator 11 at the bottom of the drying device 10. If there is no other interference, the screen sand will form a conical accumulation. In this case, it is necessary to use the reciprocating motion of the push plate 24 of the unloading pusher 20 to squeeze the screen sand and push the screen sand flat so that the screen sand can pass through the rake-tooth oscillator 11 at the bottom of the drying device 10 evenly.
[0029] Combination Figure 3 As shown, a heating device is connected to the bottom of the drying device 10; the heating device includes a blower 31 and a high-pressure hot air blower 32 connected to the blower 31, and the high-pressure hot air blower 32 is connected to the bottom of the drying device through a high-temperature resistant hose 33; the drying device 10 uses the blower 31 and the high-pressure hot air blower 32 to provide high-pressure wind for micro-heating, and the heating temperature is maintained between 20°C and 35°C, depending on the room temperature; the drying device 10 adopts a furnace plate design, and the furnace plate gap is 3 to 4 mm, so as to achieve uniform and sufficient blowing and drying of the slag sand in the furnace.
[0030] Combination Figure 3 As shown, since the unloading pusher 20 can increase the distribution gap between the screening sand, the drying device can achieve the purpose of drying the screening sand by blowing high-pressure air through the heating device. The unloading pusher 20 and the heating device cooperate with each other to evenly dry the screening sand material, play a role in preventing blockage and sedimentation, ensure the smooth vacuum transportation of the subsequent screening sand, and solve the problem of pipeline blockage in the subsequent vacuum transportation process.
[0031] To sum up, since the screen sand with a high moisture content contains oil and grease, it will cause sand to form lumps and fall onto the internal rake-tooth oscillator of the drying device. The sand-water separator drying device of the utility model uses a discharge pusher to squeeze the screen sand through the reciprocating motion of the pusher plate, thereby increasing the distribution gap between the screen sand and making the screen sand pass through the rake-tooth oscillator evenly. After that, the heating device uses high-pressure air to slightly heat the screen sand, and the purpose of drying the screen sand is achieved by blowing high-pressure air. The discharge pusher and the heating device cooperate with each other to increase the contact area between the high-pressure air and the screen sand, so that the screen sand is heated evenly, fundamentally solving the problem of subsequent vacuum conveying pipeline blockage caused by accumulation and agglomeration of the screen sand.
[0032] As one of the important technologies in the reconstruction scheme of the pre-treatment ultra-clean space of a sewage plant, the utility model improves the reconstruction scheme of the pre-treatment ultra-clean space of a sewage plant and fundamentally solves the problem of blockage of subsequent vacuum conveying pipelines due to clogging and agglomeration of screen sand.
[0033] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
