Description

Groove connecting device and chemical coagulation equipment

Technical Field

The utility model relates to a water treatment technical field, more specifically say, relate to a ally oneself with groove device, the utility model discloses still relate to a chemistry that has above-mentioned antithetical couplet groove device thoughtlessly congeals equipment.

Background

Chemical coagulation sedimentation is the most widely used technology in wastewater treatment, and sedimentation is to make suspended matters in wastewater sink under the action of gravity so as to be separated from the wastewater in the form of sludge to remove pollutants in the wastewater. In order to improve the precipitation effect, the particle size of suspended matters in the wastewater needs to be increased, so that the suspended matters in the wastewater are mutually aggregated into larger particles under the actions of coagulant compression double electric layers, adsorption electric neutralization, adsorption bridging, precipitate net capture and the like by adding a coagulant into the wastewater, thereby increasing the precipitation effect of the suspended matters.

Chemical coagulation facilities are generally composed of a pH adjusting tank, a reaction tank, a coagulation tank, a flocculation tank, and a sedimentation tank. In small and medium-sized wastewater treatment projects, chemical coagulation equipment is usually made of carbon steel lining FRP (Fiber Reinforced Polymer, short for Fiber Reinforced composite), and in order to save the use amount of steel, a tank body is usually designed to be a square conjoined structure, and an intermediate partition plate is common, so that the tank body is called as a conjoined tank.

In order to avoid the short circuit phenomenon of water flow, the water inlet of the tank body is usually designed at the upper part, and the water outlet of the tank body is designed at the diagonal position of the water inlet at the upper part. Water flows through the water inlet water baffle and then enters the tank body from the bottom, and flows through the whole tank body and then overflows from the water outlet to enter the subsequent tank body.

Because the water flow overflows from the front tank body to the rear tank body, when the water flow is initially debugged, the intermediate partition plate of the tank body can generate the condition that water exists on one side and does not exist on the other side, and the intermediate partition plate can be under the action of the water pressure on one side. However, during actual operation, water is arranged on two sides of the middle partition plate in most of time, water pressure on the two sides is offset, and the middle partition plate is not under the action of the water pressure.

When the structural strength of the tank body is designed, the condition that water exists on one side of the middle partition plate is generally considered, the reinforcing ribs are designed for reinforcement, the use amount of steel is increased, and the material cost is increased; the difficulty and the workload of the subsequent operation of the FRP lining are increased, and the labor cost is increased.

Detailed Description

The embodiment of the utility model discloses ally oneself with groove device, the cost has been practiced thrift.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the embodiment of the present invention discloses a connecting trough device, which includes a trough body, the trough body is divided into a plurality of pools 1 by partitions 2, and further includes a communicating pipe capable of communicating the bottoms of all the pools 1, and the communicating pipe is provided with a control valve.

As shown in figure 1, if the bottom of the water pool 1 is not communicated, the inlet water firstly enters a first water pool, before the water level of the first water pool is full, a second water pool is empty, and a partition plate 2 between the first water pool and the second water pool is subjected to higher and higher water pressure on one side of the first water pool; overflowing into a second water tank after the first water tank is full, the water level of the second water tank slowly rises, and the water pressure of one side of the first water tank on a partition plate 2 between the first water tank and the second water tank is slowly reduced; the partition board 2 between the second water tank and the third water tank is stressed similarly.

After the communicating pipelines are added, when water needs to enter the water pool 1 at the initial debugging stage, the bottoms of all the water pools 1 are communicated through the control valves, so that the water enters the first water pool and then simultaneously enters all the subsequent water pools 1 through the communicating pipelines at the bottom, the liquid levels of all the water pools 1 rise simultaneously, the partition plate 2 between the water pools 1 cannot be under the action of single-side water pressure, the required structural strength is greatly reduced, and the reinforcing ribs of the partition plate 2 can be cancelled, so that a large amount of material cost is saved; meanwhile, the processing difficulty and the workload of the groove body are reduced, and the labor cost is saved.

Preferably, the communication pipeline comprises a plurality of sewage branch pipes 5 arranged at the bottom of each pool 1 one by one, and a sewage main pipe 4 communicated with all the sewage branch pipes 5. This application makes rivers in the pond 1 get into blowdown house steward 4 through blowdown branch pipe 5, realizes all 1 bottoms intercommunications in pond. In the embodiment, the sewage branch pipe 5 of the tank body is used as a part of the communicating pipeline, so that the improvement on the tank body is reduced, and the structure is simplified. Of course, this application can also set up solitary pipeline in pond 1 bottom, communicates adjacent two ponds 1 to realize the same mesh that makes all ponds 1 bottoms can communicate.
