With the development of science and technology, people's dependence on water resources is getting higher and higher, and the scarcity of water resources is becoming more and more serious. Among them, the backwashing water of the filter in the urban water supply industry has always been a large aspect of water resource consumption; in the traditional method, direct discharge of water is used. Due to the large amount of backwash water in the filter (up to 5% of the filtration capacity of the filter), the content of suspended solids is high. This part of water is directly discharged, on the one hand, it causes waste of water resources, on the other hand, it causes pollution to the receiving water body, and accelerates the process of scarcity of water resources. Under the premise of resource conservation and sustainable development today, these problems are waiting for us solve.

Utility model content

The purpose of this utility model is to provide a filter tank backwashing water recovery device to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a filter backwash water recovery device, including a recovery pump, a collection pipe, a floating water intake weir, a floating water intake, a fixed track, a pulley, a water distribution flower wall and a recovery pool, the recovery water pump is set on the left side of the recovery pool, the fixed track is installed on both side walls of the recovery pool, and the floating water intake device is fixed on the fixed track through pulleys, and the bottom of the floating water intake device is provided with a floating The water inlet weir of the water intake device, and the bottom of the water inlet weir of the floating water intake device is provided with a collection pipe, and the water distribution flower wall is installed at the inner right end of the recovery pool.

Preferably, there are four fixed rails, and the four fixed rails are all fixedly installed on the inner wall of the recovery pool perpendicular to the bottom of the pool.

Preferably, a pulley is welded on the lower surface of the floating water intake device, and the pulley can slide freely on the fixed track.

Preferably, the recovery water pump is connected to the collection pipe through a hose, and a throttle valve is arranged on the hose between the recovery water pump and the collection pipe.

Preferably, the floating water intake device and the water inlet weir of the floating water intake device are an integral structure cast from non-metallic polymer materials.

Compared with the prior art, the beneficial effect of the utility model is that the structure of the filter backwash water recovery device is scientific and reasonable, and it is safe and convenient to use. The flower wall realizes the uniform distribution of water intake; the water intake device adopts the integrated setting of the floating tank and the water intake weir to ensure that the device can always get the supernatant of the pool and ensure that it continues to have a high working efficiency. During the process, the water intake The bottom of the weir is connected to the recovery water pump by a hose to ensure the regular reciprocating floating of the recovery device. The overall adoption of floating water intake effectively solves the problem of intermittent discharge of filter backwash water.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a filter backwash water recovery device, including a recovery water pump 1, a collection pipe 2, a floating water intake device inlet weir 3, a floating water intake device 4, and a fixed track 5. The pulley 6, the water distribution wall 7 and the recovery pool 8, the recovery water pump 1 is set on the left side of the recovery pool 8, the fixed rail 5 is installed on the two side walls of the recovery pool 8, and the floating water intake device 4 is fixed on the fixed side by the pulley 6. On the track 5, there are four fixed tracks 5, and the four fixed tracks 5 are fixedly installed on the inner wall of the recovery pool 8 perpendicular to the bottom of the pool, and the bottom of the floating water intake device 4 is provided with a floating water intake device inlet weir 3, and The bottom of the water inlet weir 3 of the floating water intake device is provided with a collection pipe 2. The floating water intake device 4 and the water inlet weir 3 of the floating water intake device are an integral structure when cast from non-metallic polymer materials. The recovery water pump 1 and the collection pipe 2 are connected by a hose , and the hose between the recovery water pump 1 and the collection pipe 2 is provided with a throttle valve and a pulley 6 is welded on the lower surface of the floating water intake device 4, and the pulley 6 can slide freely on the fixed track 5, and the water distribution wall 7 is installed on the The inner right end of the pool 8 is recovered.

Working principle: The backwash water of the filter passes through the drainage pipe, enters the recovery pool 8, and passes through the water distribution wall
