Specific embodiments

[0023] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] With reference to Figures 1-4 , the present utility model provides a water sample filtering device, including a support 1 and a water sample treatment tank 2 fixedly connected to the support 1. A water collection cover 3 is arranged at the top of the water sample treatment tank 2. An annular cavity 4 is opened inside the water sample treatment tank 2. An arc-shaped filter hopper 5 is rotatably connected in the annular cavity 4 through a rotating shaft. In this application, a channel is arranged inside the water sample treatment tank 2, and the channel is communicated with the annular cavity 4, so that it is convenient for water samples to be filtered and discharged through the arc-shaped filter hopper 5. At the same time, the size of the channel is the same as that of the arc-shaped filter hopper 5, so as to ensure that the incoming water samples are concentrated corresponding to the position of the arc-shaped filter hopper 5. Filter holes 51 are opened on the arc surface of the arc-shaped filter hopper 5, and there are multiple filter holes 51 to filter impurities and discharge clean water samples. A plurality of flow disturbing plates 6 are fixedly connected inside the arc-shaped filter hopper 5. A driving device 7 for rotating the arc-shaped filter hopper 5 is arranged on the water sample treatment tank 2. In this application, the driving device 7 can adopt the cooperation of a rotating motor and a belt transmission mechanism or a gear transmission mechanism to drive the arc-shaped filter hopper 5 to rotate for impurity cleaning.

[0025] A flushing pipe 8 is fixedly connected inside the water sample treatment tank 2. The flushing pipe 8 is arranged in the channel and is located directly above the arc-shaped filter hopper 5. The flushing pipe 8 sprays water under high pressure onto the rotating arc-shaped filter hopper 5. Due to the semi-circular setting of the arc-shaped filter hopper 5, that is, there is an opening, so that it is convenient to discharge the filtered impurities, and the impurities fall and are discharged through the channel.

[0026] A collection box 9 is movably arranged on the support 1. A partition 91 is fixedly connected inside the collection box 9. The inner cavity of the collection box 9 is divided into a water sample collection cavity and an impurity collection cavity by the partition 91. In this application, there are multiple supports 1, and the support 1 has an I-shaped structure, so that the collection box 9 can be conveniently pushed and moved on the support 1. By flexibly moving the collection box 9 to a position below the channel in the water sample treatment tank 2, the filtered water samples and impurities can be classified and collected.

[0027] Specifically, the water sample to be filtered is sent into the channel of the water sample treatment tank 2 at the position of the water collection cover 3. The water sample can pass through the arc-shaped filter hopper 5 sealed in the annular cavity 4, and utilize the filter holes 51 arranged on the arc-shaped filter hopper 5 and the spoiler plate 6 for water body diversion. In this way, the water body to be filtered can fully contact the filter surface formed by the filter holes 51, which is convenient for filtering and retaining the impurities in the water sample, and at the same time avoids the problem of filter blockage. The filtered sample can continue to be discharged through the lower channel and collected by the water sample collection cavity arranged on the collection box 9.

[0028] A pair of sealing strips 10 are fixedly connected to the inner ring wall of the annular cavity 4, and the arc-shaped filter hopper 5 is slidably connected to the sealing strips 10; both ends of the arc-shaped filter hopper 5 are fixedly connected with sealing sheets 11, and the sealing sheets 11 are slidably connected to the inner side wall of the annular cavity 4. In this application, the size of the sealing sheet 11 is adapted to the size of the end face of the arc-shaped filter hopper 5. In this way, when the arc-shaped filter hopper 5 rotates, the sealing performance between the arc-shaped filter hopper 5 and the annular cavity 4 can be improved; because the sealing strip 10 is fixed in the annular cavity 4, when the arc-shaped filter hopper 5 rotates, there is no accumulated water on the outer surface of the arc-shaped filter hopper 5.

[0029] A number of spoiler plates 6 arranged in the arc-shaped filter hopper 5 are all inclined, and one end of the spoiler plate 6 does not contact the inner wall of the arc-shaped filter hopper 5. In this application, a number of spoiler plates 6 are demarcated in the middle, and then a number of spoiler plates 6 are arranged in a mirror image distribution from the inside to the outside or from the outside to the inside. By the spoiler plate 6, the position of the water sample entering the filter surface of the arc-shaped filter hopper 5 is changed, which can improve the utilization rate of the filter surface of the arc-shaped filter hopper 5, reduce the problem of filter blockage, and improve the filtration efficiency at the same time.

[0030] The lower surface of the flushing pipe 8 is fixedly provided with a spray head 81. In this application, the flushing pipe 8 can be externally connected to a water source to provide a water source for flushing impurities for the arc-shaped filter hopper 5; the spray head 81 is arranged at the bottom of the flushing pipe 8 to reduce the problem of blockage of the spray head 81 when the filtered water sample enters the water sample treatment tank 2. The spray head 81 is used for spraying with increased water pressure on the arc-shaped filter hopper 5.

[0031] Specifically, when it is necessary to clean the impurities filtered on the arc-shaped filter bucket 5, the driving device 7 can be used to drive the arc-shaped filter bucket 5 to rotate at a constant speed in the annular cavity 4, and the nozzle 81 on the flushing pipe 8 can flush the surface of the arc-shaped filter bucket 5. Because the arc-shaped filter bucket 5 can rotate and cooperate with the setting of the channel, it is convenient to completely flush out the filtered impurities.

[0032] A drain pipe 12 is fixedly passed through the collecting box 9, and the drain pipe 12 is connected to the water sample collecting chamber. A valve is provided on the drain pipe 12, and the discharge of the filtered water sample in the water sample collecting chamber can be conveniently opened and closed. A collecting bucket 13 is movably provided in the impurity collecting chamber, and the collecting bucket 13 can be flexibly placed in the impurity collecting chamber so as to receive the impurities cleaned out of the water sample processing box 2 for transfer.

[0033] A pair of guide seats 14 are mirror-imaged in the water sample processing box 2. The guide seats 14 are triangular in shape and are arranged in the channel of the water sample processing box 2. The guide seats 14 can reduce the diameter of the channel in the water sample processing box 2 so as to centrally guide out the filtered water sample and flushed impurities.
