Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a water distributor for a small sewage treatment device. Background Technology

[0002] In rural areas of China, large amounts of untreated sewage are discharged directly into rivers and ponds, exceeding the environment's self-purification capacity, thus causing water pollution and affecting the quality of life.

[0003] To improve the rural living environment, numerous decentralized sewage treatment devices, such as septic tanks and septic tanks, have emerged on the market. These devices are compact, easy to install, and suitable for use in sparsely populated areas, especially in rural areas.

[0004] However, the wastewater treatment efficiency of such decentralized wastewater treatment equipment is limited. When excessive amounts of wastewater are discharged into such equipment within a certain period of time, the wastewater treatment will be incomplete, and the discharge will cause environmental pollution.

[0005] Therefore, designing a simple control device for the influent flow of a small-scale wastewater treatment plant is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a water distributor for small-scale sewage treatment equipment. This distributor has a simple structure, is easy and reliable to operate, and can accurately control the outflow of water to the small-scale sewage treatment equipment, thus avoiding environmental pollution.

[0007] The technical solution of this utility model is: a water distributor for a small sewage treatment equipment, including a box body, wherein a partition is provided in the box body to divide the box body space into a first chamber and a second chamber, and an inlet and an outlet are provided on the box body to communicate with the first chamber and the second chamber respectively, and a notch is provided on the partition, and an overflow port is provided on the side wall of the box body to communicate with the first chamber, and an adjustable return weir plate is slidably fitted on the partition in the horizontal direction, one side of the adjustable return weir plate being inclined and locked in position by adjusting bolts.

[0008] A water stabilizing plate is provided in the first chamber. One side of the water stabilizing plate is connected to the inner wall of the tank and the other side is connected to the partition plate. It is located between the water inlet and the overflow port. The bottom edge of the water stabilizing plate is spaced apart from the bottom surface of the tank.

[0009] The top edge of the water-stabilizing plate is flush with the upper edge of the box.

[0010] The partition plate has horizontally extending strip holes, and the adjusting bolt is fixed to the adjustable return weir plate and passes through the strip holes to engage with the nut threadedly.

[0011] The adjustable return weir plate has a right trapezoidal structure, with one side being a vertical side and the other side being a sloping side.

[0012] The overflow port has an inverted triangular structure.

[0013] The top of the box body is open.

[0014] Connection lugs are provided at the bottom of the box body.

[0015] Adopting the above technical solution has the following beneficial effects: 1. The water distributor supporting the small sewage treatment equipment includes a box body. A partition is provided in the box body, dividing the space of the box body into a first chamber and a second chamber. Water inlet holes and return water holes are provided on the box body, which are respectively connected to the first chamber and the second chamber. A notch is provided on the partition. That is, the sewage entering the first chamber can enter the second chamber through the notch, so that the excessive sewage can flow back to the sewage source through the return water hole, making the sewage flow rate discharged to the small sewage treatment equipment constant and avoiding the flow rate exceeding the design standard. An overflow port is provided on the side wall of the box body and is connected to the first chamber. The sewage entering the first chamber can overflow through the overflow port and enter the small sewage treatment equipment for treatment. A horizontally slidable adjustable return weir plate is provided on the partition. One side of the adjustable return weir plate is a sloping side, and its position is locked by an adjusting bolt. By controlling the position of the adjustable return weir plate, the opening range of the notch on the partition is adjusted, and then the flow rate (return flow rate) of the sewage entering the second chamber is adjusted, keeping the sewage level in the first chamber stable and making the sewage flow rate of the overflow port stable. On the basis of meeting sewage treatment, it avoids environmental pollution caused by the sewage flow rate discharged to the small sewage treatment equipment exceeding the standard.

[0016] 2. A water stabilizing plate is provided in the first chamber. One side of the water stabilizing plate is connected to the inner wall of the box body and the other side is connected to the partition, and it is located between the water inlet hole and the overflow port. There is a spacing distance between the bottom edge of the water stabilizing plate and the bottom surface of the box body. The sewage entering the first chamber through the water inlet hole needs to pass through the gap between the water stabilizing plate and the bottom surface of the box body and enter the space between the water stabilizing plate and the overflow port, avoiding water surface fluctuations and ensuring the stability of the sewage flow rate discharged through the overflow port.

[0017] 3. The adjustable return weir plate has a right trapezoidal structure, with one side being a vertical side and the other side being a sloping side. By adjusting the position of the adjustable return weir plate, using the overlapping range of its sloping side and the notch on the partition, the flow rate of the sewage in the first chamber to the second chamber is controlled, and then the overflow rate of the sewage in the first chamber is adjusted to be stable. The other side is a vertical side, increasing the moving range of the adjustable return weir plate and avoiding interference between the adjustable return weir plate and the partition.

[0018] 4. The overflow port has an inverted triangular structure, which can widely adjust the overflow water volume according to the height of the sewage level in the first chamber to meet the actual needs.

[0019] The following further describes with reference to the drawings and specific embodiments. Description of the Drawings

Specific Embodiments

[0022] Referring to Figures 1 to 4 , it is a specific embodiment of a water distributor for a small sewage treatment device. The water distributor for a small sewage treatment device includes a box body 1. The top of the box body 1 is open, and a partition board 2 is arranged in the box body 1, dividing the box body space into a first chamber 3 on the left and a second chamber 4 on the right. A water inlet hole 5 is arranged on the left side wall of the box body 1, communicating with the first chamber 3, and a water return hole 6 is arranged at the bottom on the right side of the box body, communicating with the second chamber 4. A notch 7 is arranged on the partition board 2. Specifically, the notch can penetrate the partition board along the height direction. An overflow port 8 is arranged on the front side wall of the box body 1, communicating with the first chamber 3. Specifically, the overflow port 8 has an inverted triangular structure, forming a standard 90° triangular weir. A horizontally slidable adjustable return weir plate 9 is arranged on the partition board 2. One side of the adjustable return weir plate is a bevel edge, and its position is locked by an adjusting bolt 10. In this embodiment, a horizontally extending strip hole 12 is arranged on the partition board 2. The adjusting bolt 10 is fixed on the adjustable return weir plate and passes through the strip hole and is in threaded cooperation with a nut. Specifically, the adjustable return weir plate 9 has a right trapezoidal structure, and one side is a vertical side and the other side is a bevel edge.

[0023] Furthermore, in order to avoid liquid level fluctuations, a water stabilizing plate 11 is arranged in the first chamber 3. One side of the water stabilizing plate 11 is connected to the inner wall of the box body and the other side is connected to the partition board, and it is located between the water inlet hole and the overflow port, and also between the vertical side of the adjustable return weir plate and the overflow port. The bottom edge of the water stabilizing plate has a spacing distance from the bottom surface of the box body, and the top edge of the water stabilizing plate 11 is flush with the upper edge of the box body.

[0024] Furthermore, in order to facilitate the connection of the water distributor, connecting lugs 13 are arranged at the bottom of the box body 1.

[0025] The working principle of this utility model is as follows: Wastewater enters the first chamber through the inlet via a wastewater pump. A water stabilizing plate stabilizes the water level, preventing fluctuations. Once the water level reaches a certain height, it overflows into the small wastewater treatment equipment. To control the effluent flow, the adjustable return weir plate can be moved, changing the opening range of the notch. This allows some wastewater to flow into the second chamber through the notch and back to the wastewater pump via the return water hole. Once the desired effluent flow rate is achieved, the position of the adjustable return weir plate can be repositioned to achieve more precise control of the effluent flow rate.
