Description

Technical Field

[0001] The utility model relates to the technical field of fishing port sewage treatment, in particular to a sedimentation tank for fishing port sewage treatment. Background Art

[0002] Fishing ports refer to ports that are dedicated to fishery production. They are important places for fishing boats to anchor, take shelter, load and unload catches, replenish fuel and fresh water, carry out repairs and maintenance, and for fishermen to rest. Fishing ports are usually equipped with fishing docks, fishery supply facilities, cold storage and processing facilities, fishing vessel repair facilities, etc., and are generally located near fishing grounds or sea areas rich in fishery resources to facilitate the development of fishery production. Sewage will be generated during fishing port activities, and it can only be discharged after the sewage is treated to meet the standards. Sedimentation tanks are often used in sewage treatment projects in fishing ports.

[0003] Some of the current sedimentation tanks are not equipped with preliminary filtering structures, which is not convenient for filtering sewage. Although some are equipped with filtering structures, the filtering structures are mostly set inside the sedimentation tanks, or fixed with bolts, etc., and it is difficult to clean the filtered impurities quickly when it is necessary. Secondly, when sewage is introduced into the existing sedimentation tanks, it is mostly concentrated from a single hole, which is difficult to quickly mix with the added precipitation agent, reducing the efficiency of the sedimentation treatment. Utility Model Content

[0004] The utility model aims to provide a sedimentation tank for treating sewage in a fishing port to solve the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a sedimentation tank for treating sewage in a fishing port, comprising:

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model is provided with a water inlet box, an installation groove, a collection frame and a filter net. When it is used, the sewage from the fishing port is first added into the collection frame, and a preliminary filtration is performed through the filter net to prevent the impurities in the sewage from affecting the subsequent precipitation reaction.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Figure 1 and Figure 2 All of them are appearance diagrams of the utility model, and combined with Figure 3-6 As shown, the sedimentation tank for sewage treatment in the fishing port includes a sedimentation tank body 1, a support is provided at the lower end of the sedimentation tank body 1, and the support is used to support and install the sedimentation tank body 1. A sewage pipe 5 is connected to the middle of the bottom end of the sedimentation tank body 1, and a sewage valve 6 is installed on the sewage pipe 5. Turbidity generated by the sedimentation reaction can be discharged and collected from the sewage pipe 5, and a top cover 3 is provided at the top of the sedimentation tank body 1. A dosing pipe 10 is connected to one side of the top of the top cover 3. By adding a medicament for the precipitation reaction from the dosing pipe 10, a water inlet tank 2 is fixed to the upper end of one side of the sedimentation tank body 1, and the upper end of the water inlet tank 2 The surface is concave to form an installation groove 16, and a collecting frame 11 is detachably provided in the installation groove 16. The top of the collecting frame 11 is open, and a filter screen 18 is installed on the side of the collecting frame 11 facing the sedimentation tank body 1, and a circular water outlet pipe 13 is provided at the upper end of the interior of the sedimentation tank body 1. The outer wall of the circular water outlet pipe 13 is connected to a water supply pipe 14 extending into the installation groove 16 and facing the filter screen 18, and a plurality of outlet branches 15 are evenly installed on the side of the circular water outlet pipe 13 facing the center of the sedimentation tank body 1, so that sewage can enter the sedimentation tank body 1 from multiple directions and positions.

[0028] See also Figure 2-Figure 3 As shown, a motor 4 is installed at the middle of the top end of the top cover 3, and a plurality of stirring blades 12 are installed at the bottom end of the motor 4 through a stirring rod.

[0029] Through the above technical solution:

[0030] During specific use, the fishing port sewage is sent to the water inlet tank 2, and first added into the collecting frame 11, and preliminarily filtered through the filter 18. The filtered sewage passes through the filter 18, and then is sent to the return outlet pipe 13 through the water supply pipe 14. Finally, the sewage can evenly enter the sedimentation tank body 1 through the outlet branches 15 in multiple directions and positions, which is conducive to rapid mixing with the precipitation agent added from the dosing pipe 10, thereby increasing the precipitation reaction rate.

[0031] By starting the motor 4 on the top cover 3, the output end of the motor 4 can drive the stirring rod equipped with the stirring blade 12 to rotate, thereby further accelerating the sedimentation reaction and improving the treatment efficiency of the sewage in the sedimentation tank.

[0032] Among them, see Figure 1 As shown, the support member includes a horizontal bar 7, a support bar 8 and a mounting base plate 9.
