Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0020] This utility model provides an evaporation and concentration device for treating organic wastewater, such as... Figure 1 , 2 As shown, the equipment includes a concentration tank 101, an inlet pipe 102, an outlet pipe 103, a stirring assembly 105, a heating component 106, and a baffle 107.

[0021] In this embodiment, the thickener 101 is a box-type structure. The inlet pipe 102 is fixed to the side wall of the thickener 101, and the wastewater flows into the thickener 101 through the inlet pipe 102. The outlet pipe 103 is fixed to the bottom of the thickener 101 and is used to discharge the remaining impurities after the reaction.

[0022] Heating component 106 is installed at the bottom of thickening tank 101 to heat wastewater and accelerate its evaporation; stirring component 105 is fixed inside thickening tank 101 to stir and mix wastewater and flocculant; baffle 107 is provided at the top of thickening tank 101, baffle 107 is evenly provided with a number of through holes 111, the through holes 111 are inclined, the baffle 107 with inclined through holes 111 does not affect the steam discharge and can prevent wastewater from splashing during stirring.

[0023] In a specific implementation, an outer cover can be installed above the baffle 107 to further prevent wastewater splashing during the stirring process. The outer cover includes a cover plate and a movable top plate 109. In this embodiment, the cover plate is a transparent cover plate 108 made of acrylic, glass or other materials, which facilitates observation of the mixing state of wastewater and flocculant inside the thickener 101. The transparent cover plate 108 is fixed to the side wall of the thickener 101 and covers part of the baffle 107. The transparent cover plate 108 is hollow, and the movable top plate 109 is embedded inside the transparent cover plate 108 and slidably connected to the transparent cover plate 108. The movable top plate 109 can slide out of the transparent cover plate 108 to cover the remaining area of ​​the baffle 107.

[0024] In this embodiment, the transparent cover 108 is located on one side of the top of the thickening tank 101, covering half of the baffle 107. When the movable top plate 109 is inside the transparent cover 108, the other half of the baffle 107 is exposed for flocculant addition. After the movable top plate 109 is completely slid out of the transparent cover 108, it can cover the other half of the baffle 107. For ease of operation, a handle 110 can be installed on the upper surface of the movable top plate 109, with the handle 110 installed on the side of the movable top plate 109 away from the transparent cover 108.

[0025] like Figure 3 , 4 As shown, the stirring assembly 105 includes a support rod 112, a drive motor 113, a drive shaft 114, a connecting rod 115, and a stirring section 116. The support rod 112 is fixed to the lower part of the thickening tank 101. The drive motor 113 is mounted on the support rod 112. The drive shaft 114 is located on the central axis of the thickening tank 101. The bottom end of the drive shaft 114 is connected to the output end of the drive motor 113, and the top end of the drive shaft 114 is fixed to the middle of the connecting rod 115. Two stirring sections 116 are symmetrically arranged at both ends of the connecting rod 115. The drive motor 113 drives the drive shaft 114 to rotate, thereby causing the connecting rod 115 to rotate, which in turn causes the stirring section 116 to rotate around the drive shaft 114.

[0026] Specifically, the mixing unit 116 includes a mounting base 117, a mixing motor 118, a mixing shaft 119, and mixing components 120. The mixing motor 118 is fixed to the connecting rod 115 via the mounting base 117, and the output end of the mixing motor 118 is connected to the top end of the mixing shaft 119. Several mixing components 120 are uniformly fixed to the mixing shaft 119. The mixing motor 118 drives the mixing shaft 119 to rotate, thereby driving the mixing components 120 to rotate, accelerating the mixing of wastewater and flocculant.

[0027] To facilitate faster wastewater discharge, the bottom of the thickener 101 is equipped with a frustum structure. The large-diameter end of the frustum structure is fixedly connected to the side wall of the thickener 101, and the outlet pipe 103 is fixedly connected to the small-diameter end of the frustum. Figure 3 As shown, the heating element 106 is disposed inside the frustum structure. The heating element 106 consists of a fixed base 121 and a heating plate 122. The fixed base 121 is installed on the inner wall of the frustum structure, and the heating plate 122 is fixedly connected to the fixed base 121. The heating plate 122 is used to accelerate the evaporation and concentration of wastewater. The bottom of the concentration tank 101 may also be provided with support legs 123. The support legs 123 are respectively disposed at the four corners of the bottom of the concentration tank 101 and located on the periphery of the frustum structure. The support legs 123 can support and raise the concentration tank 101, making it easier to catch the discharged impurities and crystals from below.

[0028] When using this invention, wastewater is injected into the thickening tank 101 through the inlet pipe 102. The movable top plate 109 is slid along the handle 110 to expose the area of ​​the baffle 107 not covered by the transparent cover 108. Flocculant is then added, and it flows into the thickening tank 101 through the through-holes 111 on the baffle 107. The movable top plate 109 is then slid in the opposite direction to cover the baffle 107. The drive motor 113 drives the drive shaft 114 to rotate, which in turn drives the connecting rod 115 to rotate, and the rotation of the connecting rod 115 stimulates the agitator. Part 116 rotates around drive shaft 114; at the same time, stirring motor 118 drives stirring shaft 119 to rotate, driving stirring component 120 to rotate, accelerating the mixing of wastewater and flocculant. During the mixing process, baffle 107 will block splashed water droplets; then the wastewater is heated by heating component 106 and evaporated. During the heating process, handle 110 needs to be pulled to expose baffle 107. Through hole 111 can effectively prevent splashing while ensuring smooth discharge of water vapor. Finally, the remaining impurities are discharged through water outlet pipe 103.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
