Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a high-pressure chamber anti-backflow and anti-clogging feeding system. Background Technology

[0002] Currently, one method for treating wastewater containing slag is through fermentation in a high-pressure chamber. During the fermentation process, scum rises to the surface of the wastewater, while sediment settles to the bottom of the high-pressure chamber, thus achieving solid-liquid separation. However, when wastewater containing slag enters the high-pressure chamber, it easily clogs the feed pipe due to the large amount of scum it contains. During the fermentation process, the pressure inside the high-pressure chamber increases, and the wastewater will flow back along the feed pipe under the pressure, affecting normal operation. Utility Model Content

[0003] The present invention aims to at least partially solve the aforementioned technical problems. Therefore, the objective of this invention is to provide a high-pressure chamber anti-backflow and anti-clogging feeding system.

[0005] A high-pressure chamber anti-backflow and anti-clogging feeding system includes a feed pipe, at least one feed pump on the feed pipe, and a one-way valve on the feed pipe. The one-way valve includes at least one one-way valve coaxial with the feed pipe and at least one one-way valve off-axis with the feed pipe; the outlet of the last feed pump is located inside the high-pressure chamber.

[0006] Preferably, the feed pump includes a first feed pump and a second feed pump, which are connected by a connecting pipe.

[0007] Preferably, the connection point between the connecting pipe and the first feed pump is at the same position, lower than, or higher than the connection point between the connecting pipe and the second feed pump. The inlet of the first feed pump is connected to the sludge collection tank.

[0008] Preferably, the high-pressure chamber is equipped with an exhaust pipe, a slag discharge pipe, and a liquid discharge pipe, and each of the exhaust pipe, slag discharge pipe, and liquid discharge pipe is equipped with a pressure regulating valve.

[0010] The beneficial effects of this utility model are as follows:

[0011] The present invention provides a high-pressure chamber anti-backflow and anti-clogging feeding system. The feeding pump on the feeding pipe can break up coarse residues in the sewage to prevent clogging of the feeding pipe.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings herein can generally be arranged and designed in various different configurations.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, this embodiment of a high-pressure chamber anti-backflow and anti-clogging feeding system includes a feed pipe, a first feed pump 1, and a second feed pump 2. The first feed pump 1 and the second feed pump 2 are connected by a connecting pipe 3, which is a section of the feed pipe. A one-way valve 4 is provided on the connecting pipe 3. The one-way valve 4 includes at least one one-way valve coaxially arranged with the connecting pipe 3 and at least one one-way valve off-axis arranged with the connecting pipe 3. The inlet of the first feed pump 1 is connected to the sludge collection tank 7, and the outlet of the second feed pump 2 is located inside the high-pressure chamber 5.

[0020] After the sewage collects in the collection tank 7, the first feed pump 1 and the second feed pump 2 are started. The sewage enters the high-pressure chamber 5 sequentially through the first feed pump 1, the connecting pipe 3, and the second feed pump 2. During this process, coarse residues in the sewage are broken up. The connection point between the connecting pipe 3 and the first feed pump 1 is at the same level, lower, or higher than the connection point between the connecting pipe 3 and the second feed pump 2. The connecting pipe 3 makes the sewage flow smoother and further prevents blockage.

[0021] The high-pressure chamber 5 is nearly sealed. The high-pressure chamber 5 is equipped with an exhaust pipe 8, a slag discharge pipe 9, and a liquid discharge pipe 10. Each of the exhaust pipe 8, slag discharge pipe 9, and liquid discharge pipe 10 is equipped with a pressure regulating valve 11. The pressure regulating valve 11 is used to regulate the pressure inside the high-pressure chamber 5 and will open when the pressure exceeds the preset value to ensure safe use. The three pressure regulating valves 11 are set to the same pressure value to ensure the pressure of the high-pressure chamber 5 is stable and can achieve continuous feeding and continuous discharge.

[0022] A power pump 6 is also installed on the slag discharge pipe 9. During the sewage fermentation process, the one-way valve coaxially mounted on the connecting pipe 3 is closed to prevent the high-pressure sewage in the high-pressure chamber 5 from flowing back. The one-way valve mounted off-axis is located before the coaxial one-way valve. When the off-axis one-way valve opens, the sewage in the feed pipe before the off-axis one-way valve is emptied. The sewage flows back to the sludge collection tank 7 to prevent sewage from accumulating and clogging the feed pipe. At the same time, the feed pipe is empty during the next feed to reduce the power load. Under high pressure, the solid sludge in the sewage settles to the bottom of the high-pressure chamber 5. The power pump 6 is started, and the sludge can be discharged through the slag discharge pipe 9. The liquid generated during the process enters the liquid discharge pipe 10 and is then discharged. The generated gas is discharged from the exhaust pipe 8.

[0023] The high-pressure chamber 5 is equipped with a series-parallel connector 12 that communicates with the interior of the high-pressure chamber 5. Depending on the processing capacity, one, two, or more high-pressure chambers 5 can be connected in series or in parallel, or multiple integrated production facilities can be designed. The series-parallel connectors 12 of different high-pressure chambers are connected by pipes and fittings to achieve interconnection between the high-pressure chambers 5 and meet the requirements of different scales of daily sewage treatment. At the same time, multiple integrated equipment can also be designed in series or in parallel.

[0024] like Figure 2 As shown, in another embodiment, only a first feed pump 1 is provided on the feed pipe, and a one-way valve 4 is installed on the feed pipe after the first feed pump 1.

[0025] like Figure 3 As shown, in another embodiment, the one-way valve 4 includes a one-way valve coaxially arranged with the feed pipe and at least one one-way valve coaxially arranged with the feed pipe.

[0026] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
