PREFERRED EMBODIMENT
[0019] The technical scheme of the utility model will be more clearly and completely described in combination with the drawings and the description of the preferred embodiment of the utility model.
[0020] As shown in the drawings, Figure 1 The preferred embodiment of the utility model is an automatic cleaning filter, which comprises a separation pipeline 1 and a debris pipeline 2, the separation pipeline 1 cuts and extrudes the debris in sewage, and then automatically enters the debris pipeline 2, and the debris pipeline 2 automatically removes debris regularly.
[0021] The debris pipeline 2 is a vertically arranged hollow pipe body, and the separation pipeline 1 is also a hollow pipe body. One end of the separation pipeline 1 is connected to the side wall of the debris pipeline 2, and the inner cavities of the two are communicated. The end of the separation pipeline 1 away from the debris pipeline 2 is arranged in an inclined upward direction. The included angle α between the separation pipeline 1 and the debris pipeline 2 is between 75° and 85°. The inclined separation pipeline 1 is beneficial to facilitate the debris to enter the debris pipeline 2 more easily under the action of gravity and extrusion of the separation pipeline 1.
[0022] The separation pipeline 1 is a rotationally symmetrical hollow pipe body. The separation pipeline 1 is provided with a reamer 11 and a filter screen 12 arranged outside the reamer 11. The filter screen 12 is a hollow cylindrical structure. The reamer 11 is a spiral blade structure with a shaft in the middle. The end of the separation pipeline 1 away from the debris pipeline 2 is provided with a motor 14. The shaft of the reamer 11 is connected to the driving shaft of the motor 14 through a sealing device 13. The reamer 11 rotates along its axis under the driving of the motor 14. The sealing device can adopt a sealing shaft commonly used in the prior art. The spacing L between the outer periphery of the reamer 11 and the inner wall of the filter screen 12 is between 1 mm and 5 mm. This not only protects the cutting blades of the reamer 11, but also is beneficial to cutting and grinding debris.
[0023] The reamer 11 and the filter screen 12 form a relatively independent debris separation channel. The debris separation channel extends along the axis of the separation pipeline 1 in the cavity of the separation pipeline 1. The separation pipeline 1 is provided with a water inlet 16 and a water outlet 17. The water inlet 16 and the water outlet 17 form a water flow channel for water flow. The water flow channel intersects with the debris separation channel. The water containing debris enters the separation pipeline 1 through the water inlet 16, separates the debris from the water through the debris separation channel, and the separated debris enters the debris pipeline 2, and the separated water flows out through the water outlet 17.
[0024] The water inlet 16 is arranged above the end of the separation pipeline 1 away from the debris pipeline 2 and is vertically arranged. The water inlet 16 extends into the separation pipeline 1 to the inside of the filter screen 12 and is located at the starting end of the debris separation channel. The debris flows along the running direction of the debris separation channel with the water flow, which can reduce the possibility of debris entanglement and reduce the phenomenon of blockage. The end of the separation pipeline 1 away from the debris pipeline 2 is provided with a baffle 15. The baffle 15 is arranged at the starting end of the debris separation channel to prevent the possibility of debris accumulation, especially mud accumulation, at the starting end of the debris separation channel.
[0025] The water outlet 17 is arranged below the separation pipeline 1 near one end of the sundry pipeline 2, and the water outlet 17 is vertically arranged, and the starting end of the water outlet 17 is obviously lower than the ending end of the sundry separation channel. The end of the water outlet 17 away from the sundry pipeline 2 is provided with a drainage cavity 18, and the drainage cavity 18 is a large-area concave structure. Under the joint action of the two, the water flow can be guided to flow out from the water outlet 17 (in the case of gravity water flow), so that the water flow entering the sundry chamber is reduced, the water content of the sundries in the sundry chamber is reduced, and the treatment efficiency is improved.
[0026] The water outlet 17 is further provided with a flow meter 19 for monitoring the flow of the water flow.
[0027] The bottom outlet of the sundry pipeline 2 is in the shape of a bucket, which is beneficial to the sliding and collection of the sundries. The end of the bottom outlet of the sundry pipeline 2 is provided with an automatic valve 21, and the upper part of the sundry pipeline 2 is provided with a sensor 22 for monitoring the position of the sundries in the sundry pipeline 2.
[0028] In addition, an automatic control system is further included, and the controller and the electrical system of the automatic control system adopt the mature technical solutions in the prior art. When the sensor 22 senses that the position of the sundries in the sundry pipeline 2 reaches the set depth, the automatic valve 21 is opened to automatically remove the sundries. The rotation speed of the motor 14 is automatically controlled according to the change of the water flow of the water outlet 17, and when the flow meter 19 monitors that the water flow of the water outlet 17 is obviously less than the water inflow, at this time, the sundries are more, the motor 14 is controlled to rotate fast, the cutting and extruding speed of the sundries is accelerated, and the smoothness of the water flow channel is ensured.
[0029] Specific implementation process: the water mixed with sundries enters the sundry separation channel from the water inlet 16, and under the action of the motor 14, the reamer 11 rotates continuously, and in this process, most of the sundries are in the sundry separation channel, and a small part of the sundries is inside the filter screen 12 due to the influence of the water flow. This part of the sundries is cut and crushed under the action of the cutting blade of the reamer 11, and finally all the sundries enter the sundry pipeline 2 through the spiral channel and are continuously extruded and pushed. In this process, the water flow first flows along the sundry separation channel (this process can make the sundries walk along the water flow, and reduce the deposition on the filter screen 12), and then is separated vertically from the sundry separation channel. Figure 2 ① in the figure is a water flow schematic diagram, and ② is a sundry flow schematic diagram.
[0030] The above specific embodiments only describe the preferred embodiments of the utility model, and do not limit the protection scope of the utility model. Under the premise of not departing from the design concept and spirit category of the utility model, various deformations, substitutions and improvements of the technical scheme of the utility model made by the ordinary skilled in the art according to the textual description and drawings of the utility model should belong to the protection category of the utility model. The protection scope of the utility model is determined by the claims.
