Description

Technical Field

[0001] This utility model relates to the field of microfiltration technology, and in particular to a flat-plate microfiltration machine. Background Technology

[0002] Microfilters are essential wastewater treatment equipment in industrialized aquaculture. They primarily separate larger particles and suspended solids from the water through physical interception, thus purifying the water. Their working principle relies on a filter screen with specific pore sizes, allowing water to pass through while trapping larger particles on one side, achieving solid-liquid separation. Microfilters are indispensable wastewater treatment equipment in industrialized aquaculture, and in various industrial production and environmental treatment scenarios, their high efficiency and stable filtration performance have made them a key device for ensuring water quality. Currently, the main type of microfilter is the hub-and-spoke microfilter, which has high manufacturing costs and high energy consumption. The biggest drawback of hub-and-spoke microfilters is their inability to promptly separate uneaten feed and feces from the water. This leads to the continuous dissolution and fermentation of ammonia nitrogen from fish feces and uneaten feed, resulting in the depletion of dissolved oxygen and the production of nitrites, thus worsening water quality. Utility Model Content

[0003] The purpose of this invention is to provide a flat-plate microfilter that can completely separate solid particles from water. It can quickly intercept and separate larger impurities, suspended solids, uneaten food, and feces from water, preventing them from dissolving in water to release ammonia nitrogen and disintegrating and fermenting to produce nitrite, thereby effectively purifying the water. The specific technical solution is as follows:

[0004] A flat-plate microfiltration machine includes a support frame, an inlet tank, an inlet, a sludge collection tank, an outlet, an outlet tank, a second guide rail, a filter screen, a nozzle, and a sliding base;

[0014] This invention effectively separates solid particles from water by installing a filter screen at an angle in the outlet tank. It quickly intercepts and separates larger impurities, suspended solids, uneaten food, and feces from the water, preventing them from dissolving into ammonia nitrogen and fermenting to produce nitrite, thus effectively purifying the water. Furthermore, when the filter screen becomes clogged, a spray nozzle can be activated.

Finally, the angled installation of the filter screen, along with the natural overflow and flushing action of the water flow, allows solid particles to move more smoothly into the collection tank, achieving highly efficient solid-liquid separation. Compared to some traditional microfiltration machines, this method offers higher separation efficiency and better results. Attached Figure Description

The embodiments of this utility model will now be described based on its overall structure.

[0025] Example 1

[0026] As shown in the figure, a flat-plate microfiltration machine includes a support frame, a water inlet tank, a water inlet, a sludge collection tank, a water outlet, a water outlet tank, a second guide rail, a filter screen, a nozzle, and a sliding base.

[0027] The upper end of the support frame is equipped with an inlet tank, an outlet tank, and a sludge collection tank; the outlet tank has an inlet tank on the left and a sludge collection tank on the right; the filter screen is installed at an angle in the middle of the outlet tank, with its left end connected to the inlet tank and its right end connected to the sludge collection tank; the second guide rail is installed below the filter screen; the bottom surface of the sliding base is connected to the second guide rail, and the top surface is equipped with a nozzle; the left side of the inlet tank is equipped with a water inlet; and the bottom surface of the outlet tank is equipped with a water outlet.

[0028] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0029] The support frame provides support. Water enters from the inlet on the left side of the inlet tank, and an opening is provided on the right side of the inlet tank. The left side of the filter screen is connected to the opening on the right side of the inlet tank. After the water enters the inlet tank, the water level rises to the height of the opening on the right side of the inlet tank, and the water overflows from the inlet tank, forming an overflow. The overflowing water flows onto the filter screen. The water filtered by the filter screen falls into the outlet tank and leaves the filtration device from the outlet on the bottom of the outlet tank. Particulate matter filtered by the filter screen remains on top of the screen. Solid particles above the filter screen are continuously flushed towards the collection tank by water that cannot pass through the screen in time, until all water passes through the screen, achieving complete separation of solid particles and water. As this process continues, solid particles accumulate above the screen. Simultaneously, due to the gradual clogging of the screen, the overflowing water travels a longer distance on the screen, continuously pushing the accumulated debris towards the collection tank until it is pushed in. When the water approaches the collection tank, the screen is clogged with solid particles. At this point, the spray nozzle is activated. The second guide rail of the nozzle moves the nozzle mounted on the sliding base, spraying water from below the screen. The impact force of the water clears the solid particles clogging the screen, re-unclogging it. The flushed solid particles move along the screen into the collection tank, completing the cleaning process. The spray nozzle obtains water from an external water pipe to rinse the screen.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that it also includes a first guide rail, a baffle, and a connecting rod; the baffle is positioned above the filter screen; the connecting rod is positioned to the left of the baffle; the first guide rail is mounted on the housing of the water outlet trough to the right of the baffle; the upper end of the connecting rod is connected to the left side of the baffle, and the lower end is connected to the sliding base; the right end of the baffle is connected to the first guide rail.

[0032] The baffle acts as a barrier, and the connecting rod connects the baffle and the sliding base. When the sliding base moves the nozzle on the second guide rail, the baffle moves along with the sliding base. The water sprayed from the nozzle passes through the filter screen and is blocked by the baffle, preventing the rinsing water from splashing upwards. The first guide rail is used to fix the other end of the baffle, and a slider is provided at the other end of the baffle. The slider rests against the first guide rail to fix the first guide rail.

[0033] The working principle of this embodiment is the same as that of Embodiment 1.

[0034] Example 3

[0035] The difference between this embodiment and Embodiment 2 is that the baffle is trapezoidal, sealed at the top, and open at the bottom; the lower opening of the baffle faces the direction of the nozzle. The trapezoidal shape of the baffle prevents water from splashing off the sides when it hits the baffle, further enhancing its blocking effect.

[0036] The working principle of this embodiment is the same as that of Embodiment 1.

[0037] Example 4

[0038] The difference between this embodiment and embodiment 3 is that the connecting rod includes a first horizontal bar, a vertical bar, and a second horizontal bar; the first horizontal bar is provided at the upper end of the vertical bar, and the second horizontal bar is provided at the lower end; one end of the first horizontal bar is connected to the side of the baffle, and the other end is connected to the upper end of the vertical bar; one end of the second horizontal bar is connected to the sliding base, and the other end is connected to the lower end of the vertical bar. The first horizontal bar is used to connect the baffle and the vertical bar, and the second horizontal bar is used to connect the sliding base and the vertical bar, so that when the sliding base moves on the second guide rail, it drives the baffle to move together.

[0039] The working principle of this embodiment is the same as that of Embodiment 1.

[0040] Example 5

[0041] The difference between this embodiment and embodiment 4 is that a water inlet tank cover is installed on the top surface of the water inlet tank; one end of the water inlet tank cover is hinged to the top surface of the water inlet tank, and the other end covers the top surface of the water inlet tank. By installing the water inlet tank cover on the top surface of the water inlet tank, the cover can cover the top surface of the water inlet tank, and when workers need to maintain or inspect the water inlet tank, they can easily open the water inlet tank cover to observe the situation inside the water inlet tank.

[0042] The working principle of this embodiment is the same as that of Embodiment 1.

[0043] Example 6

[0044] The difference between this embodiment and Embodiment 5 is that a top plate is installed on the top surface of the water outlet tank, and a side cover is installed on the right side. The top plate covers the top surface of the water outlet tank. The side cover is vertically positioned, with its upper end hinged to the right side of the water outlet tank and its lower end extending downwards. The top plate and side cover serve as an isolation mechanism, facilitating maintenance and repair of the water outlet tank by personnel, ensuring its normal operation, and contributing to the stable operation of the entire microfiltration unit.

[0045] The working principle of this embodiment is the same as that of Embodiment 1.

[0046] Example 7

[0047] The difference between this embodiment and Embodiment 6 is that the sludge collection trough is installed below the side cover of the outlet trough, with the right end of the sludge collection trough located outside the side cover and the left end located inside the side cover. This installation, with the right end outside the side cover and the left end inside, facilitates easy observation and cleaning of the sludge within the trough by staff.

[0048] The working principle of this embodiment is the same as that of Embodiment 1.

[0049] Example 8

[0050] The difference between this embodiment and embodiment 7 is that a handle is installed on the outside of the water tank side cover. By installing a handle on the outside of the water tank side cover, it is more convenient to operate the handle when it is necessary to open or close the water tank side cover.

[0051] The working principle of this embodiment is the same as that of Embodiment 1.

[0052] In summary, this invention, by installing a filter screen at an angle in the water outlet tank, effectively achieves complete separation of solid particles from water. It can quickly intercept and separate larger impurities, suspended solids, uneaten food, and feces from the water, preventing them from dissolving into ammonia nitrogen and fermenting to produce nitrite, thus effectively purifying the water. Furthermore, when the filter screen becomes clogged, the spray nozzle can be activated. Driven by the second guide rail, the nozzle sprays water to clean the filter screen, using the impact force of the water to unclog it and ensure that the filter screen maintains good filtration performance at all times. This eliminates the need for frequent manual cleaning of the filter screen, saving labor costs and ensuring continuous and stable operation of the equipment. Finally, the angled installation of the filter screen, along with the natural overflow and flushing action of the water flow, allows solid particles to move more smoothly into the collection tank, achieving highly efficient solid-liquid separation. Compared to some traditional microfiltration machines, this method offers higher separation efficiency and better results.
