Description

Technical Field

[0001] The utility model relates to the technical field of rainwater utilization in industrial plants, in particular to a rainwater drainage system for industrial plants. Background Art

[0002] The mineral processing industry consumes a large amount of water, and the water shortage in the northern region leads to high water costs. Rainwater is a high-quality water resource, but there has always been a problem of large water volume in a short period of time and difficulty in collecting and utilizing it, resulting in the direct discharge of precious rainwater resources. When the rainfall increases in a short period of time, local floods may occur, and low-lying areas are in danger of being submerged. In winter in the northern region, outdoor rainwater drainage pipes are stored with snow water, causing pipes to freeze and crack, posing a huge safety hazard. The water quality requirements for the mineral processing industry are not too strict, and rainwater will not have a negative impact after entering the production system. Utility Model Content

[0003] In order to solve the problem that the external rainwater drainage pipes of industrial plants in northern regions are often frozen in winter and the outflow of rainwater in summer causes flood damage in local areas, the purpose of the utility model is to provide an industrial plant rainwater drainage system that can effectively protect the rainwater drainage pipes and collect and utilize rainwater.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses an industrial plant rain drainage system, comprising: a rain collecting bucket, a drainage branch pipe, a drainage main pipe, a water collecting pool, and a process pump; wherein:

[0006] Several rain collecting buckets are installed in the gutters and drainage troughs of industrial plants. The elevation of the rain collecting buckets is slightly lower than the elevation of the bottom of the gutters and drainage troughs. They are sealed with the bottom of the gutters and drainage troughs to prevent water leakage and are used to collect rainwater.

[0007] The upper part of each drainage branch pipe is connected to a rain collecting bucket, and the lower part is connected to the drainage main pipe;

[0008] The outlet at the bottom of the drainage main pipe directly enters the water collection tank or utilizes the existing ditch on the factory floor and connects the outlet pipe to the ditch;

[0009] The process pump utilizes the process pump in the ditch pump pool in the industrial plant to pump the collected rainwater into the production system.

[0010] Furthermore, the drainage branch pipes and the drainage main pipe are all placed in the factory building.

[0011] Furthermore, industrial plants are generally provided with a trench pump pool, and the water collection pool utilizes the existing trench pump pool of the plant.

[0012] Furthermore, a filtering device is also provided in the water collection tank, and the water filtered by the filtering device is pumped into the production system by a process pump.

[0013] Furthermore, each rain collecting bucket is covered with a filter screen which is easy to disassemble.

[0014] Furthermore, each of the filter screens is a stainless steel conical screen with a smooth surface, which is used to reduce floating objects from covering the screen and thus reducing blockage.

[0015] Furthermore, the stainless steel conical net is a two-half split structure with a hinged top, and a tension spring is arranged inside the stainless steel conical net to pull the stainless steel conical net closed; a plurality of slots or blocks are arranged on the circumferential side of the top of the rain collecting hopper, and blocks or slots adapted to the slots are arranged on the bottom of the stainless steel conical net; a pull ring is fixed on the outer circumference of each half of the stainless steel conical net with the two-half split structure to facilitate stretching it open.

[0016] Furthermore, rainwater flowing into gutters and drainage channels will enter rainwater collecting hoppers, and will be collected through drainage branch pipes and drainage main pipes and flow into collection tanks. The rainwater in the collection tanks will be directly pumped into the production system by process pumps, or the rainwater in the collection tanks will be filtered and treated before being pumped into the production system by process pumps.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are:

[0018] The purpose of this utility model is to solve the problem that the external rainwater drainage pipes of industrial plants in northern China are often frozen in winter and the rainwater outflow in summer causes flood damage in local areas. It can effectively protect the rainwater drainage pipes and collect and utilize rainwater. For example, the annual rainfall in the Bayan Obo mining area is 240mm on average, the floor area of ​​a plant is 4600 square meters, and the annual rainwater collection is about 1100m 3 One plant can collect 1100m 3 , if the remaining factory buildings are fully utilized, the rainwater collection effect will be better.

[0019] The filter net arranged on the rain collecting hopper in the utility model is a stainless steel conical net, which is a two-part split structure with a hinged top, and a tension spring is arranged inside the net to pull the stainless steel conical net closed; a plurality of slots or blocks are arranged around the top of the rain collecting hopper, and a block or slot matching the slot is arranged at the bottom of the stainless steel conical net; a pull ring is fixed on the outer circumference of each half of the stainless steel conical net of the two-part split structure to facilitate stretching and opening it (it is in an automatic closing state under the action of the tension spring, and its size in the closed state matches that of the rain collecting hopper to achieve a better closing effect). Since the stainless steel conical net has a smooth surface, it is not easy to gather floating objects, nor is it easy to be covered and blocked by floating objects. In particular, the structural design greatly facilitates the disassembly, installation and cleaning of the filter net. BRIEF DESCRIPTION OF THE DRAWINGS
