Description
Technical Field
[0001] The utility model relates to the technical field of river channel pollution-cleaning ships, in particular to a dehydrated and solidified sewage filtering and discharging device for river channel pollution-cleaning ships. Background Art
[0002] River pollution cleaning boats are also called river dredging boats, which are tools for removing underwater sediments. They are generally powered by diesel engines and electric motors. The hull, or floating body, adopts an assembled box-type structure and is composed of a dredging device, a power device, a transmission device, etc. The dredging device is usually driven by power to remove underwater sediments, and then the dredging device is sent to the designated location by the transmission device. These underwater sediments are mixed with sewage. After dehydration and solidification, the sludge can be used in power generation, soil fertilization or sewage treatment. The removed sewage is simply treated and then discharged.
[0003] According to the search, the Chinese patent website with patent number CN218166243U discloses "a kind of sewage filter after dehydration and solidification for river cleaning ships". By setting an upper baffle, a lower baffle, a first filter plate, a second filter plate, a third filter plate and a movable plate, the position of the movable plate is adjusted and the upper and lower baffles block the water, so that the larger impurities in the sewage are retained at the bottom of the water, and then the larger impurities at the bottom are flushed out and discharged through water flushing. The sewage is smoothly filtered through multiple filter plates of different properties, so that the sewage is better treated, and the discharged sewage will not cause great harm to the water body discharged into it. However, the method for flushing the larger impurities accumulated at the bottom of the device is water flushing, which will consume more water resources and is not conducive to the efficient use of resources. In addition, when flushing, multiple filter plates need to be removed or lifted, and the operation process is relatively complicated. Utility Model Content

[0010] By adopting the above technical solution, when the first motor is started, it drives the feeding screw fixedly connected to it to rotate, and then utilizes the rotation of the feeding screw to continuously push the water flow that has not yet flowed out of the water outlet and the intercepted larger impurities forward, thereby avoiding blockage of the front water outlet.
[0011] Furthermore, a plurality of water outlet holes are provided, and the plurality of water outlet holes are evenly distributed along the bottom of the circular cylinder.
[0012] By adopting the above technical solution, the arrangement of multiple water outlet holes at the bottom of the circular cylinder allows the sewage to be continuously and evenly released and larger impurities to be intercepted as the feeding screw moves forward.
[0013] Furthermore, the device body is connected to the liquid receiving cavity through a through hole.
[0014] By adopting the above technical solution, the water flow after the initial impurity removal received in the liquid receiving cavity can smoothly enter the device body through the through hole for further sewage treatment.

[0017] Furthermore, the second motor is fixedly connected to the rotating rod, and the rotating rod is fixedly connected to the baffle.
[0018] By adopting the above technical solution, when the second motor is started, it drives the rotating rod fixedly connected to it to rotate, thereby causing the baffle fixedly connected to the rotating rod to rotate.

[0024] By adopting the above technical solution, the external controller controls the operation of the first motor, the solenoid valve and the second motor, which can make their operation process more accurate.
[0025] In summary, the utility model mainly has the following beneficial effects:
[0026] 1. The utility model provides a liquid receiving chamber, a circular cylinder, a feeding screw and a water outlet, so that the dehydrated and solidified sewage first enters the circular cylinder. When the feeding screw rotates, the sewage and impurities are continuously pushed forward. During its movement, the water flows smoothly into the liquid receiving chamber through the water outlet, and enters the device body through the subsequent through holes to participate in the layer-by-layer filtration process. Large impurities are successfully intercepted in the circular cylinder. With the continuous pushing of the feeding screw, they are discharged from the slag outlet and are uniformly collected and processed. In the process of simple filtration and treatment of sewage, large impurities can be separated without additional consumption of water resources. The treatment process is simple and fast.
[0027] 2. The utility model provides a solenoid valve, a second motor and a baffle, and the on and off status of the solenoid valve and the second motor can be flexibly controlled by an external controller. When the speed of water flowing through the first filter plate, the second filter plate and the third filter plate is significantly slowed down and the water flow accumulates, it is easy to cause sewage overflow. At this time, the solenoid valve and the second motor can be controlled to close the liquid inlet pipe and the through hole to prevent new water from continuously flowing in. When there is no water flowing out of the drain pipe, each filter plate can be removed and replaced in turn to facilitate the smooth progress of the subsequent filtration process.

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0035] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:
[0036] A device for filtering and discharging dehydrated and solidified sewage for a river cleaning ship, such as Figure 1-Figure 5As shown, the device comprises a main body 1, a first filter plate 8, a second filter plate 9, a third filter plate 10 and a drain pipe 11. A primary impurity removal mechanism 2 is arranged on one side of the main body 1. The primary impurity removal mechanism 2 comprises a liquid receiving chamber 201 and a circular cylinder 203. A first motor 204 is arranged on one side of the circular cylinder 203. A feeding screw 205 is arranged on the output end of the first motor 204. A liquid inlet pipe 207 is arranged on one side of the top of the circular cylinder 203. A water outlet 206 is arranged at the bottom of the circular cylinder 203. A slag outlet is arranged on the side of the circular cylinder 203 away from the first motor 204. 208. A through hole 4 is provided on the device body 1. The setting of the primary impurity removal mechanism 2 can perform primary impurity removal and filtration on the sewage to separate larger impurities in the sewage. The larger impurities can be directly separated during the filtration process and collected and processed in a unified manner to ensure that the impurity removal process does not consume additional water resources for flushing. At the same time, the separation process is simple and fast without the need to dismantle related structural components. It can further alleviate the processing pressure of the first filter plate 8, the second filter plate 9 and the third filter plate 10, and delay the moment when the first filter plate 8, the second filter plate 9 and the third filter plate 10 reach the processing limit.
[0037] See also Figure 1 , Figure 2 , Figure 3 The first filter plate 8, the second filter plate 9 and the third filter plate 10 are all engaged and slidable with the device body 1. Pull rings are provided on the tops of the first filter plate 8, the second filter plate 9 and the third filter plate 10. The connection method between the first filter plate 8, the second filter plate 9 and the third filter plate 10 and the device body 1 makes the process of replacing each filter plate simpler and faster. At the same time, the setting of the pull rings on the tops of each filter plate can facilitate the temporary fixation of the special lifting tools and the filter plates when replacing the filter plates.
[0038] See also Figure 3 The first motor 204 is fixedly connected to the feeding screw 205, and the feeding screw 205 is adapted to the inner wall of the circular cylinder 203. When the first motor 204 is started, it drives the feeding screw 205 fixedly connected thereto to rotate, and then utilizes the rotation of the feeding screw 205 to continuously push the water flow that has not yet flowed out of the water outlet 206 and the intercepted larger impurities forward, thereby avoiding the blockage of the front water outlet 206 and ensuring the smooth progress of the sewage primary impurity removal process. The high adaptability of the feeding screw 205 to the circular cylinder 203 ensures that the rotation of the feeding screw 205 will neither damage the circular cylinder 203 nor ensure that the water flow and the intercepted impurities are smoothly transmitted forward.
[0039] See also Figure 1 , Figure 3 , Figure 5There are multiple water outlet holes 206, and the multiple water outlet holes 206 are evenly distributed along the bottom of the circular cylinder 203. The arrangement of the multiple water outlet holes 206 at the bottom of the circular cylinder 203 allows the sewage to continuously and evenly release the water flow as the feeding screw 205 continues to move forward, and intercepts larger impurities, so that the sewage filtration process is continuously carried out at multiple positions of the circular cylinder 203, ensuring that the initial filtration process of the sewage is carried out smoothly and orderly.
[0040] See also Figure 1 , Figure 2 The device body 1 is connected to the liquid receiving chamber 201 through the through hole 4. The water flow after the initial impurity removal received in the liquid receiving chamber 201 can smoothly pass through the through hole 4 into the device body 1 for further sewage treatment. When the water flow passes through the first filter plate 8, the second filter plate 9 and the third filter plate 10 in the device body 1 in sequence, smaller impurities, tiny impurities, suspended colloids and bacteria and viruses are removed by the filter plates of different properties in sequence, ensuring that the treated water flow will not pollute the water body discharged into it and other species living in the water body. Embodiment 2:
[0041] See also Figure 1 , Figure 2 , Figure 4 A baffle 7 is provided at the through hole 4, a rotating rod 6 is provided in the middle of the baffle 7, a second motor 5 is provided on the top of the rotating rod 6, an electromagnetic valve 3 is provided at the liquid inlet pipe 207, and a guide plate 202 is provided inside the liquid receiving chamber 201. When the second motor 5 is started, the rotation of the rotating rod 6 and the baffle 7 can be controlled, so that the baffle 7 can be used to change the state of the through hole 4, so as to adjust the sewage filtering and discharging device after dehydration and solidification for river cleaning ships to a normal filtering state, or replace the filter plate state, and the guide plate 202 can guide the received water flow to the through hole 4.
[0042] See also Figure 1 , Figure 2 , Figure 4 The second motor 5 is fixedly connected to the rotating rod 6, and the rotating rod 6 is fixedly connected to the baffle 7. When the second motor 5 is started, it drives the rotating rod 6 fixedly connected thereto to rotate, and then the baffle 7 fixedly connected to the rotating rod 6 rotates, thereby opening or closing the through hole 4, playing the role of releasing or cutting off the water flow, so as to cooperate with different operating states of the device body 1.
[0043] See also Figure 1 , Figure 2 , Figure 4The baffle 7 is a circular plate-shaped structure, and the baffle 7 is adapted to the through hole 4. The baffle 7 with a circular plate-shaped structure is consistent with the shape of the through hole 4. When the baffle 7 rotates to be parallel to the through hole 4 under the action of the second motor 5, the through hole 4 can be blocked to prevent water from passing through. When the baffle 7 is no longer parallel to the through hole 4 under the action of the second motor 5, the water flows through smoothly for subsequent processing.
[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 The guide plate 202 is located below the water outlet 206 and is arranged in an arc shape and tilted. The arc structure of the guide plate 202 and the downward tilted arrangement toward the through hole 4 enable the water dripping from the water outlet 206 to smoothly move to the side of the through hole 4 after dripping on the guide plate 202, and to be smoothly introduced into the interior of the device body 1 through the through hole 4, thereby avoiding the water flow after the initial impurity removal treatment from being retained in the liquid receiving chamber 201, and ensuring that the water flow passes through the through hole 4 as much as possible.
[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The first motor 204, the solenoid valve 3 and the second motor 5 are all connected to the external controller, and the external controller controls the operation of the first motor 204, the solenoid valve 3 and the second motor 5, which can make their operation process more accurate and the required response time shorter, thereby improving the accuracy and speed of the operation of the dehydrated and solidified sewage filtering and discharging device for the entire river pollution cleaning ship.
[0046] The implementation principle of the utility model is as follows: first, the solenoid valve 3 is controlled to open the liquid inlet pipe 207, and the first motor 204 and the second motor 5 are controlled to start at the same time, the second motor 5 drives the rotating rod 6 and the baffle 7 to rotate, and the through hole 4 is opened, and the first motor 204 drives the feeding screw 205 to rotate smoothly; thereafter, after the sewage enters the circular cylinder 203 from the liquid inlet pipe 207, the sewage moves forward with the rotation of the feeding screw 205. During the forward movement, due to the existence of the water outlet hole 206, the water flow falls smoothly, and the impurities with a larger aperture than the water outlet hole 206 are successfully intercepted in the circular cylinder 203 and continuously pushed forward by the feeding screw 205. After the synergistic effect of the longer circular cylinder 203, the feeding screw 205 and the continuously existing water outlet hole 206, the sewage and the larger impurities are separated, until the larger impurities are pushed to the slag outlet 208, and are uniformly collected and processed at the slag outlet 208; then, the sewage passes smoothly through the water outlet hole 206. The water drips onto the guide plate 202 inside the liquid receiving chamber 201, and smoothly enters the device body 1 from the opened through hole 4 through the guiding effect of the guide plate 202, and then passes through the first filter plate 8, the second filter plate 9 and the third filter plate 10 for filtering layer by layer in turn, and finally is smoothly discharged from the drain pipe 11; when the sewage filtration speed slows down significantly, the water accumulates at the device body 1, and is even about to overflow, the solenoid valve 3 on the liquid inlet pipe 207 is controlled to be closed by the external controller, so that the liquid inlet pipe 207 no longer passes new sewage to be treated, and at the same time the second motor 5 is started, driving the rotating rod 6 and the baffle 7 to rotate in the opposite direction to close the through hole 4. When the sewage accumulated in the device body 1 is completely treated and no water is discharged from the drain pipe 11, the staff uses a lifting tool to fix it on the pull rings on the top of the first filter plate 8, the second filter plate 9 and the third filter plate 10, so as to facilitate its removal from the device body 1 and replacement.
[0047] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
