Description

Technical Field

[0001] The utility model relates to the field of sewage purification, in particular to a concentrated water bucket. Background Art

[0002] Tail water, tail gas, etc. generated in the fields of aquaculture, environmental protection, etc. need to meet the emission standards before they can be discharged. In some tail water recovery, tail gas recovery or sewage recovery processes, it is often necessary to use concentrated water barrels to collect wastewater or concentrated liquid or sewage in the recovery process, concentrate a certain amount, and then discharge the wastewater or concentrated liquid manually or by pumps; since the inlet and outlet of the existing concentrated water barrels are generally set as conventional inlets and outlets, most of them can only achieve ordinary sewage storage (concentrated liquid storage), liquid discharge or sewage discharge, and the functions are very simple. It is even more difficult to achieve more accurate solid and liquid discharge. In view of this, the inventor of the present invention has conducted in-depth research on the above-mentioned defects in the existing technology, and thus this case was created. Utility Model Content

[0006] Furthermore, a multi-way valve is provided on the outside of the liquid inlet, and the multi-way valve is connected to the solid-liquid separation agent for accelerating the solid-liquid separation of the waste liquid while connecting the waste liquid. The solid-liquid separation agent is pumped out from a dosing device through a dosing pump, and the solid-liquid separation agent and the waste liquid are fully mixed through the multi-way valve.

DETAILED DESCRIPTION

[0018] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0019] like Figure 1-3 As shown, the concentrated water barrel 4 adopts a cylindrical tank body 6, the bottom of the cylindrical tank body 6 is funnel-shaped, and a sewage outlet 42 is provided at the bottom thereof. The sewage outlet 42 is connected to a sludge pump 45, and the sludge pump 45 further extracts the sludge at the bottom of the cylindrical tank body 6 to an external device, such as a sludge stirring device or a spiral sludge treatment device, to dry and recover the sludge; a liquid inlet 62 and a high-pressure clean water inlet 63 are provided at the top of the cylindrical tank body 6; a high-pressure clean water pipe 64 passes through the high-pressure clean water inlet 63 and is connected inwardly, and a plurality of branch pipes 641 are provided in the tank, and a head 642 is provided at the end of each branch pipe. The high-pressure clean water pipe 64 is connected to the external clean water pump 21, as shown in FIG. Figure 3 As shown, the clean water pump 21 is connected to a clean water tank 83, and high-pressure clean water (or other cleaning agents) is introduced through the clean water pump 21 and sprayed through the spray head 642 to flush the sludge adhered to the inner wall of the cylindrical tank body 6;

[0020] The liquid inlet 62 is used to inject dirty liquid or concentrated liquid that needs to be collected, stored, or treated. The liquid inlet 62 is generally connected to the previous device to inject dirty liquid or concentrated liquid filtered or deposited by the previous device. The previous device can be a sand filter tank, a tailwater pool, a filter device, etc. This embodiment discloses a sand filter tank; the side wall of the cylindrical tank body 6 is provided with a clear liquid outlet 65, and a fixed end 661 of a hose 66 is connected and fixed to the side wall clear liquid outlet 65. The free end 662 of the hose 66 forms a water inlet, and the free end 662 of the hose 66 is configured with a floating body so that the water inlet of the free end 662 of the hose 66 always floats below the liquid level 67 in the cylindrical tank body 6. The hose 66 can extract the supernatant in the tank under the suction force of the concentrate pump.

[0021] As shown in the figure, in this embodiment, the floating body is a hollow float 663 sealed at the free end 662 of the hose 66. The free end 662 of the hose 66 slightly extends out of the hollow float 663. A small amount of liquid 664 is built into the hollow float 663 to ensure that due to gravity, the free end 662 of the hose 66 always floats below the liquid level 67 in the cylindrical tank body 6. As the supernatant is sucked out, the liquid level 67 drops and the hollow float 663 also drops. Therefore, during the suction process, the free end 662 of the hose 66 is always below the liquid level 67 and can just suck up the upper liquid level 67.

[0022] like Figure 3 As shown, a multi-way valve 8 is provided outside the liquid inlet 62. The multi-way valve 8 is connected to the solid-liquid separation agent for accelerating the solid-liquid separation of the waste liquid while connecting the waste liquid. The solid-liquid separation agent is pumped outward from a dosing device 82 through a dosing pump 81, and the solid-liquid separation agent and the waste liquid are fully mixed through the multi-way valve 8.

[0023] In a specific embodiment, a liquid level sensing device 68 is further provided in the concentrated water tank 4. In this embodiment, an ultrasonic liquid level sensor is used. The liquid level sensing device 68 is used to detect the high and low levels of the liquid in the concentrated water tank 4 and feed the above signal back to a controller. When the liquid level in the concentrated water tank 4 reaches a preset low level, the controller is turned on. Figure 1 As shown, the controller issues a control command to shut down the pump that inputs concentrated liquid to the liquid inlet 62, and opens the spray head 642 to flush the inner wall of the cylindrical tank 6 for a predetermined time by introducing clean water from the clean water tank 83 through the clean water pump 21; when the liquid level in each concentrated water bucket 4 reaches a preset high level, as shown in FIG. Figure 2 As shown, the controller issues a control command to shut down the pumps supplying liquid from the liquid inlet 62 and the cleaning port 63. Once the hose continues to pump the supernatant liquid, causing the liquid level 67 to drop to a predetermined position, the pumps supplying liquid from the liquid inlet 62 and the cleaning port 63 are restarted. In practice, the controller can also control the frequency and duration of the fresh water spraying, as well as the duration and frequency of the water supply to the liquid inlet 62, based on actual conditions. This prevents overflow due to excessively high liquid levels or impacts on solid-liquid separation due to excessively low liquid levels.

[0024] The above embodiments and illustrations do not limit the product form and style of the present invention. Any appropriate changes and modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
