Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an anti-clogging sewage treatment device. Background Art
[0002] Sewage usually refers to the discharged water from life and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants in sewage include pathogen pollutants, oxygen-depleting pollutants, plant nutrients and toxic pollutants. All types of sewage often need to be filtered before treatment. However, there are too many impurities in sewage, especially domestic sewage, which is often mixed with solid impurities such as egg shells, rotten vegetable leaves, etc. The existing sewage treatment equipment lacks components for cutting impurities and exporting filtered impurities at the same time when filtering sewage. These solid impurities can easily cause blockage to the filtering equipment, which also leads to the need for frequent cleaning and replacement of sewage filtering equipment, which not only increases the cost of sewage treatment, but also reduces the efficiency of sewage treatment. Utility Model Content
[0003] In view of the above problems, the purpose of the present utility model is to provide a sewage treatment device that is anti-clogging and solves the problems raised in the above background technology.
[0004] To achieve the above objectives, the utility model adopts the following technical solution: an anti-clogging sewage treatment device, comprising a first treatment box, a second treatment box arranged below the first treatment box, a support frame arranged outside the first treatment box and used to support the first treatment box and the second treatment box, an inlet pipe arranged at the top of the first treatment box, an outlet pipe arranged at the bottom of the second treatment box, and a filtering device arranged between the first treatment box and the second treatment box, wherein the filtering device comprises a rotating rod rotatably connected to the middle of the first treatment box, a motor arranged at the top of the rotating rod, a cutting knife arranged on the outer wall of the rotating rod and used to crush larger impurities, a filter cover installed at the bottom end of the rotating rod and rotatably connected to the top of the second treatment box, and an impurity collection box arranged on the outer wall of the second treatment box and connected to the first treatment box.
[0005] The beneficial effects of the utility model are as follows: in the process of sewage treatment, not only can the domestic garbage in the sewage be crushed to reduce its volume, avoiding clogging of the pipeline or retention on the filter cover and the filter plate during the circulation process to affect the filtration efficiency, but also it is convenient to guide the impurities on the filter cover and the filter plate to the impurity collection box for collection during sewage filtering, thereby further reducing the probability of blockage and improving the efficiency of sewage treatment.
[0006] In order to facilitate the removal of impurities filtered from the filter cover into the impurity collection box:
[0007] As a further improvement of the above technical solution: the filter cover is configured to be conical.
[0008] The beneficial effect of this improvement is that when the motor drives the rotating rod to rotate, it drives the filter cover to rotate along the top of the second processing box, and directly throws the impurities filtered on the filter cover into the impurity collection box.
[0009] To reduce the chance of filter clogging:
[0010] As a further improvement of the above technical solution: a mounting rod is arranged on the inner wall of the first processing box and above the filter cover, and a cleaning brush for cleaning impurities on the filter cover is arranged at the bottom end of the mounting rod.
[0011] The beneficial effect of this improvement is that as the filter cover rotates, the cleaning brush slides along the outer wall of the filter cover, thereby cleaning the impurities remaining on the filter cover and reducing the probability of clogging of the filter cover.
[0012] In order to discharge the impurities on the filter plate into the impurity collection box along the slag discharge port for centralized collection:
[0013] As a further improvement of the above technical solution: support plates are installed on the left and right sides inside the second processing box, and fixing rods are provided on the tops of the support plates. A filter plate slidably connected to the fixing rods is provided between the two support plates, and a spring is installed on the outer wall of the fixing rod and between the support plate and the filter plate. The side wall of the second processing box is provided with a slag discharge port connected to the impurity collection box.
[0014] The beneficial effect of this improvement is that after the sewage is filtered through the filter cover, it is filtered for the second time through the filter plate. When the sewage falls on the filter plate, the elastic action of the spring can drive the filter plate to vibrate up and down, so that the impurities are discharged into the impurity collection box along the slag discharge port for centralized collection, thereby avoiding impurities in the sewage from being retained on the filter plate.
[0015] To further reduce the chance of mesh clogging:
[0016] As a further improvement of the above technical solution: the filter plate is installed in an inclined state, wherein the horizontal line of the support plate on the left side is higher than the horizontal line of the support plate on the right side.
[0017] The beneficial effect of this improvement is that the filter plate is set to be inclined, which can facilitate the impurities to be guided along the filter plate to the sewage outlet, thereby preventing the impurities from being retained on the filter plate and further reducing the probability of mesh blockage.
[0018] In order to facilitate the discharge of impurities from the impurity collection box:
[0019] As a further improvement of the above technical solution: a slag discharge pipe is arranged at the bottom of the impurity collection box and on the side close to the bottom end of the filter plate, and a slag guide plate is arranged inside the impurity collection box, and the thickness of the slag guide plate gradually decreases from the side far away from the slag discharge pipe to the side close to the slag discharge pipe.
[0020] The beneficial effect of this improvement is that when the impurities in the impurity collecting box are full, the slag discharge pipe is opened, so that the impurities are guided to the slag discharge pipe along the slag guide plate and discharged along the slag discharge pipe.
[0021] In order to prevent large solid impurities from blocking the pipes or being retained on the filter plates and filter covers during the circulation process, thus affecting the filtration efficiency:
[0022] As a further improvement of the above technical solution: the cutting knives are arranged in two groups, the two groups of cutting knives are perpendicular to each other and are distributed on the outer wall of the rotating rod from top to bottom.
[0023] The beneficial effect of this improvement is that by setting up two sets of mutually perpendicular cutting knives, larger solid impurities can be cut to reduce their volume, avoiding clogging of pipelines during circulation or retention on filter plates and filter covers that affects filtration efficiency, thereby facilitating smooth sewage treatment.

The impurity collection box 10 connected to the first treatment box 1 can not only crush the domestic garbage in the sewage to reduce its volume during the sewage treatment process, but also avoid clogging the pipeline or being trapped on the filter cover 9 and the filter plate 15 during the circulation process to affect the filtration efficiency. At the same time, it is convenient to guide the impurities on the filter cover 9 and the filter plate 15 to the impurity collection box 10 for collection during sewage filtering, thereby further reducing the probability of clogging and improving the efficiency of sewage treatment. The filter cover 9 is configured to be conical. When the motor 7 drives the rotating rod 6 to rotate, it drives the filter cover 9 to rotate along the top of the second treatment box 2, and directly throws the impurities filtered on the filter cover 9 into the impurity collection box 10. The inner wall of the first treatment box 1 and above the filter cover 9 are provided with an installation A mounting rod 11 is provided at the bottom end of the mounting rod 11 with a cleaning brush 12 for cleaning impurities on the filter cover 9. As the filter cover 9 rotates, the cleaning brush 12 slides along the outer wall of the filter cover 9 to clean the impurities remaining on the filter cover 9, thereby reducing the probability of clogging of the filter cover 9. Support plates 13 are provided on the left and right sides of the interior of the second processing box 2. Fixed rods 14 are provided on the tops of the support plates 13. A filter plate 15 slidably connected to the fixed rods 14 is provided between the two support plates 13. A spring 16 is provided on the outer wall of the fixed rod 14 and between the support plate 13 and the filter plate 15. A slag discharge port 19 connected to the impurity collection box 10 is provided on the side wall of the second processing box 2. When sewage passes through the filter cover 9 After filtration, secondary filtration is performed through the filter plate 15. When sewage falls on the filter plate 15, the elastic action of the spring 16 can drive the filter plate 15 to vibrate up and down, so that impurities are discharged into the impurity collection box 10 along the slag discharge port 19 for centralized collection, thereby preventing impurities in the sewage from being retained on the filter plate 15. The installation state of the filter plate 15 is inclined, wherein the horizontal line of the support plate 13 on the left side is higher than the horizontal line of the support plate 13 on the right side. The filter plate 15 is set to be inclined, which can facilitate the impurities to be guided along the filter plate 15 to the sewage discharge port, thereby preventing impurities from being retained on the filter plate 15, further reducing the probability of mesh blockage. A slag discharge pipe 17 is provided at the bottom of the impurity collection box 10 and on the side close to the bottom end of the filter plate 15.The impurity collecting box 10 is provided with a slag guide plate 18 inside, and the thickness of the slag guide plate 18 gradually decreases from the side far away from the slag discharge pipe 17 to the side close to the slag discharge pipe 17. When the impurities in the impurity collecting box 10 are full, the slag discharge pipe 17 is opened, so that the impurities are guided to the slag discharge pipe 17 along the slag guide plate 18 and discharged along the slag discharge pipe 17. The cutting blades 8 are provided in two groups, and the two groups of the cutting blades 8 are perpendicular to each other and are distributed from top to bottom on the outer wall of the rotating rod 6. By providing two groups of mutually perpendicular cutting blades 8, larger solid impurities can be cut to reduce their volume, avoid clogging the pipeline during the circulation process or staying on the filter plate 15 and the filter cover 9 to affect the filtration efficiency, and facilitate the smooth progress of sewage treatment.
[0032] The working principle and use process of the utility model are as follows: when the equipment is used, sewage is introduced into the first treatment box 1 along the water inlet pipe 4. At this time, the motor 7 drives the rotating rod 6 and the cutting knife 8 to rotate, and the impurities such as domestic garbage in the sewage are crushed. The crushed impurities may fall on the filter cover 9. When the motor 7 drives the rotating rod 6 to rotate, the filter cover 9 is driven to rotate along the top of the second treatment box 2, and the impurities filtered on the filter cover 9 are directly thrown into the impurity collection box 10. As the filter cover 9 rotates, the cleaning brush 12 slides along the outer wall of the filter cover 9, and the impurities remaining on the filter cover 9 can be cleaned to reduce the probability of clogging of the filter cover 9. After the sewage is filtered by the filter cover 9, it is filtered twice through the filter plate 15. When the sewage falls on the filter plate 15, under the elastic action of the spring 16, the filter plate 15 can be driven to vibrate up and down, so that the impurities are discharged into the impurity collection box 10 along the slag discharge port 19 for centralized collection, so as to avoid the impurities in the sewage being retained on the filter plate 15. The treated sewage falls into the second treatment box 2 and is discharged along the outlet pipe 5.
