Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a rake-tooth oscillator for a sand-water separator drying device. Background Art
[0002] During 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 trouble and impact on the subsequent treatment process.
[0003] The screenings sand produced by the sand-water separator is generally transported by a belt conveyor or a screw conveyor to the press and then sent to a trash can after being squeezed. It is then collected by manual transportation 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 environment of the screening sand collection and transportation workshop and solve the time-consuming and labor-intensive problem of manual transportation, the sewage treatment plant pretreatment area was deeply analyzed and studied. Finally, the original open ground sewage pretreatment area was transferred to an underground sealed space for treatment. The vacuum adsorption principle was used to transport the screening sand and other garbage from various places to the ground layer through a closed pipeline for transportation. On this basis, the transformation of the sewage treatment plant pretreatment ultra-clean space was completed. However, due to the characteristics of the screening sand in the sand-water separator, it needs to be dried. However, the sand-water separator drying device has the following shortcomings: (1) The screening sand will become compacted during the drying process, which will cause blockage in the subsequent transportation system; (2) The screening sand will form a cone-shaped accumulation inside the drying device, which will cause uneven heating of the material during the drying process, affecting the heating efficiency and increasing the energy consumption of the equipment.

[0028] In order to better understand the above - mentioned technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.
[0029] During the operation of the sewage treatment plant, the original above - ground sewage pretreatment of sand - water separation is transferred to an underground sealed space, and the grid residue sand is transported to the ground layer for transfer through pipeline - type closed transportation by using the principle of vacuum adsorption. At the same time, devices such as crushing, dewatering, and drying equipment are equipped in the underground sealed space to facilitate the treatment of the grid residue sand generated in the sewage pretreatment process. The above - ground part can be transformed into a garden - style landscape, thereby reducing environmental pollution during sewage treatment, effectively improving the plant environment of the sewage treatment plant, and enhancing the air quality of the plant area, so as to carry out the transformation of the ultra - clean space for sewage pretreatment in the sewage treatment plant.
[0030] The present utility model is one of the important technologies in the transformation plan of the ultra - clean space for sewage pretreatment in the sewage treatment plant. Through the timed oscillation of the rake - tooth oscillator, the screening of the grid residue sand is realized. The fine sand particles fall into the subsequent vacuum conveying system, and the large - sized agglomerates are retained and crushed by other means, avoiding the agglomeration of the grid residue sand and solving the problem that the traditional drying device blocks the pipeline due to the agglomeration of the grid residue sand during the drying process, and improving the stability of the grid residue sand transportation of the sand - water separator.
[0031] Combined with Figure 1 、 Figure 2As shown in the figure, a rake-shaped oscillator for a drying device of a sand-water separator provided by the utility model includes a pneumatic vibrator 10, a connecting rod 12, a screw rod connecting plate 13, and a plurality of rake teeth 14. The pneumatic vibrator 10 is arranged on the top of the drying device 20 of the sand-water separator. An air inlet and an air outlet are provided on the pneumatic vibrator 10. One end of the connecting rod 12 passes through the top of the drying device 20 of the sand-water separator and is connected to the pneumatic vibrator 10 device, and the other end of the connecting rod 12 is connected to the screw rod connecting plate 13. The screw rod connecting plate 13 is arranged near the lower part of the drying device 20 of the sand-water separator. A plurality of rake teeth 14 are symmetrically arranged on both sides of the screw rod connecting plate 13. The rake-shaped oscillator uses the vibration generated by the pneumatic compressed air of the pneumatic vibrator 10 to drive the connecting rod 12 and the screw rod connecting plate 13 to act, so that fine sand particles fall from the gaps between the plurality of rake teeth 14, leaving the larger-volume grid slag sand in the drying device 20 of the sand-water separator, avoiding the problem of blockage of the subsequent conveying pipeline caused by the caking of the grid slag sand, and ensuring the smooth conveying of the grid slag sand.
[0032] Combined with Figure 1 As shown in the figure, the pneumatic vibrator 10 can adopt a GT16 pneumatic vibrator. The pneumatic vibrator 10 is installed on the top of the drying device 20 of the sand-water separator through a bracket 11. The bracket 11 is fixed on the drying device 20 of the sand-water separator through a bolt 15 and a compression spring 16 sleeved on the bolt 15. Among them, the bolt 15 is a half-thread bolt, and the lower part of it is sleeved with a compression spring 16 to ensure the stability of the installation of the pneumatic vibrator 10.
[0033] Combined with Figure 1 、 Figure 2 As shown in the figure, a rubber sleeve 17 is provided at the connection between the connecting rod 12 and the drying device 20 of the sand-water separator. On the one hand, it can ensure the sealing performance of the drying device 20 of the sand-water separator, and on the other hand, it can ensure the stability of the connection between the connecting rod 12 and the drying device 20 of the sand-water separator.
[0034] Combined with Figure 1 As shown in the figure, the screw rod connecting plate 13 includes a cross plate 131 perpendicular to the connecting rod 12 and folding plates 132 symmetrically arranged on both sides of the cross plate 131. The included angle α between the folding plate 132 and the cross plate 131 is 150°. A plurality of rake teeth 14 are installed on both sides of the screw rod connecting plate 13, such as 52.
[0035] Combined with Figure 1 As shown in the figure, when a plurality of rake teeth 14 are installed, they do not come into contact with the drying device of the sand-water separator, so as to avoid damage to the rake teeth 14. The distance between adjacent rake teeth 14 is 6-9 mm, so that fine sand particles can fall from the gaps between the plurality of rake teeth 14.
[0036] Combined with Figure 1As shown in the figure, the pneumatic vibrator 10 adopts a timed oscillation method to achieve timed screening of the grid residue sand, reducing manual intervention. At the same time, through the pneumatic vibrator 10, it is also possible to prevent the grid residue sand from forming a conical accumulation inside the drying device of the sand-water separator, avoiding uneven heating of the grid residue sand during the drying process.
[0037] In a specific embodiment, an air cannon is provided on the drying device 20 of the sand-water separator to repeatedly impact the large plate agglomerates remaining in the drying device of the sand-water separator until they are broken and fall, preventing the grid residue sand from caking and solving the problem of pipeline blockage caused by material caking during the drying process in traditional drying equipment, improving the performance and reliability of the equipment.
[0038] Combined with Figure 1 As shown in the figure, the working principle of the rake-tooth oscillator of the drying device of the sand-water separator is that the vibration generated by the pneumatic compressed air of the pneumatic vibrator 10 drives the connecting rod 12 and the screw rod connecting plate 13 to act, so that the fine sand particles are screened by multiple rake teeth 14 and fall into the subsequent vacuum conveying system. The larger agglomerated materials will continue to remain in the drying device 20 of the sand-water separator, and the agglomerated materials will be completely crushed by the impact of the air cannon and then fall into the vacuum conveying system, ensuring the smoothness of the material conveying process. The utility model adopts a timed oscillation method, which can reduce the energy consumption of the equipment, reduce manual intervention, improve the operation efficiency, and ensure the stable operation of the equipment.
[0039] The transformation of the ultra-clean space in the pretreatment of the sewage treatment plant is a major engineering project in Shanghai and also the first application in the pretreatment area of the sewage treatment plant. As an important technology in the transformation plan of the ultra-clean space in the pretreatment of the sewage treatment plant, the utility model improves the transformation plan of the ultra-clean space in the pretreatment of the sewage treatment plant. Through the oscillation of the rake-tooth oscillator, it can effectively prevent the grid residue sand from causing pipeline blockage during the subsequent conveying process due to large-scale caking, improve the production efficiency, reduce the manual intervention and maintenance difficulty, and reduce the failure rate of the equipment.
