Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a reverse discharge port device for cleaning a spiral pipeline. Background Art

[0002] In the daily operation of a sewage treatment plant, the screen is the first treatment process that sewage goes through after entering the sewage treatment plant. The screen residue obtained through the screen is generally transported to a trash can by a belt conveyor or a screw conveyor, and then collected by manual pushing and transported out for treatment. However, this method will cause a poor environment in the treatment workshop and is time-consuming and labor-intensive.

[0003] Therefore, in order to solve the problems of poor treatment workshop environment and 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 residue, grit and other garbage from various places to the ground layer through a closed pipe for transportation, while the above-ground part can be transformed into a garden-style landscape, and on this basis, the transformation of the ultra-clean space of the sewage plant pretreatment was completed. However, the spiral conveying pipeline used for vacuum adsorption transportation of screen residue is generally in a timed and intermittent operation state. Once the spiral conveying device fails to discharge materials normally, it will inevitably affect the normal operation of the equipment and require manual inspection and maintenance of the entire conveying pipeline. At the same time, the maintenance cost is high. The spiral conveying pipeline has the following problems when unloading: (1) The accumulated dirt is difficult to clean, and the discharge port is difficult to access, making the cleaning of the accumulated dirt difficult, which may cause blockage or equipment damage; (2) The cleaning efficiency is low. The traditional method of cleaning the spiral conveying discharge port requires manual operation, and the cleaning process is time-consuming and unstable; (3) Since the cleaning work usually depends on regular maintenance or is carried out when problems occur, it may cause serious accumulation of dirt, affecting the normal operation of the equipment.

[0018] 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.

[0019] During the operation of the sewage treatment plant, the open sewage pretreatment on the ground is transferred to the underground sealed space, and the screen residue is transported to the ground layer through a closed pipeline using the vacuum adsorption principle. At the same time, the underground sealed space is equipped with crushing, dehydration, drying equipment and other devices to facilitate the treatment of various screen residues with different properties 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 improving the air quality in the plant area, thereby completing the transformation of the sewage treatment plant pretreatment ultra-clean space.

[0020] As one of the important technologies in the reconstruction plan of the ultra-clean space of the sewage treatment plant, the utility model installs a reversing discharge port device at the discharge port at the end of the spiral pipe of the screw conveyor during the vacuum adsorption and transportation of the grid residue. When the discharge port is blocked, there is no need to dismantle the entire spiral pipe, and the reversing discharge port device can be directly dismantled to clean the discharge port in time and efficiently, thereby solving the blockage problem of the discharge port of the screw conveyor and ensuring smooth discharge.

[0021] Combination Figure 1 , Figure 2 As shown, the utility model provides a reverse discharge port device for cleaning a spiral pipe, which is arranged at the end of a spiral pipe 1 of a screw conveyor, and the reverse discharge port device includes a rotating short pipe 2 rotatably connected to the end of the spiral pipe 1 and a discharge port 4 perpendicular to the rotating short pipe 2; the rotating short pipe 2 matches the spiral pipe 1, and the rotating short pipe 2 includes a first pipe segment 21 and a second pipe segment 22 connected by bolts, which can ensure that the rotating short pipe 2 is easy to disassemble and install, and is convenient for subsequent cleaning or maintenance work. One end of the discharge port 4 is connected to the side wall of the rotating short pipe 2, and the other end is connected to the drying device 6.

[0022] Combination Figure 1 , Figure 2As shown, a connection port 3 for installing a reversing discharge port device is provided at the end of the spiral pipe 1, and a rotation gap 5 is left between the top of the connection port 3 and the reversing discharge port device, so that the reversing discharge port 4 device can rotate easily; a sealing member is provided at the connection between the spiral pipe 1 and the reversing discharge port device, so as to ensure the sealing performance of the pipe. In a specific embodiment, the sealing member is a sealing gasket or a sealing rubber ring, which ensures that the connection between the rotating short pipe 2 and the spiral pipe 1 is sealed reliably.

[0023] Combination Figure 2 As shown, the discharge port 4 of the reverse discharge port device is connected and fixed to the drying equipment 6 by bolts, so that when blockage occurs, the bolts can be removed, and the reverse discharge port device can be rotated to clean the end of the spiral pipe 1.

[0024] Combination Figure 3 As shown in (a) and (b), when the end of the spiral pipe 1 is clogged with material, it is only necessary to remove the bolts between the discharge port 4 and the drying device 6 and rotate the reverse discharge port 4 device to clear the clog 7.

[0025] Therefore, when the end of the spiral pipe is blocked, the reverse discharge port device can be removed for cleaning without dismantling the entire spiral pipe. This avoids serious blockage of screen residue due to untimely cleaning, which may cause the equipment to not operate normally, and provides technical guarantee for the safe and reliable transportation of the screw conveyor.

[0026] To sum up, the utility model installs a reversing discharge port device for cleaning the spiral pipe at the end of the spiral pipe, so that the discharge port can be cleaned in time when it is blocked.
