Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, and specifically, to a wastewater treatment device for the production of bio-organic fertilizers. Background Art

[0002] During the production of bio-organic fertilizers, the discharge of wastewater is inevitable. The wastewater often contains a large amount of organic matter, solid suspended matter, and slag. If these wastes are not effectively treated, they will cause serious pollution to the environment. The organic matter and solid suspended matter contained in the wastewater often include plant residues, fertilizer solutions, and other impurities in the production process. Especially during the treatment process, the slag in the wastewater may affect the normal operation of the equipment, resulting in frequent blockages of the filtration system, increasing the production cost, and affecting the wastewater treatment efficiency. How to efficiently treat the wastewater generated during the production of bio-organic fertilizers has become an urgent problem to be solved in the current environmental protection field.

[0003] Currently, in terms of wastewater treatment, many traditional treatment devices adopt physical filtration, chemical reactions, and biological treatment methods, but these methods all have their own limitations: for example, existing wastewater treatment devices usually use physical means such as filter screens and filter plates to filter wastewater and remove solid particles or suspended matter therein. Although this method is simple and intuitive, during long-term operation, the filter plate is prone to blockage due to the deposition of slag. Once the filter plate is blocked, the flow rate of the wastewater will be significantly reduced, the filtration effect will be seriously affected, and the equipment needs to be shut down regularly for cleaning. The cleaning work is not only time-consuming but also increases the maintenance cost of the equipment. At the same time, when traditional devices treat wastewater, they fail to effectively recover the slag generated in the wastewater. The slag in the wastewater often needs to be manually cleaned or recovered by manual or other external devices, lacking an automated recovery system. In addition, the recovered slag contains a certain amount of wastewater and is not effectively compressed, resulting in low treatment efficiency and difficulty in the rational utilization of the slag.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present invention.

[0022] A medicine adding hopper 15 is fixed on the left side of the device body 1. The bottom end of the medicine adding hopper 15 is communicated with the top of the inner cavity of the mixing chamber 2. A discharge pipe 16 communicating with the bottom of the inner cavity of the mixing chamber 2 is fixed on the bottom wall of the left side of the device body 1, and an electromagnetic valve 17 is installed on the discharge pipe 16.

[0023] In this embodiment, wastewater generated in the production process of biological organic fertilizer is added to the water inlet chamber 4 through the feed frame 9. The slag in the wastewater stays on the top wall of the device body 1 under the action of the filter plate 10, and the wastewater enters the mixing chamber 2 through the first water guiding through groove 5 at the bottom of the water inlet chamber 4. The arranged cleaning assembly 13 can push the slag staying on the filter plate 10 into the slag discharge chute 6 under the drive of the double-shaft motor 12, avoiding the blockage of the filter plate 10 by the slag. At the same time, the arranged extrusion assembly 18 can intermittently compress the slag in the slag discharge chute 6.

[0024] Embodiment 2 As Figure 4 and Figure 6 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes: The cleaning assembly 13 includes a rotating plate 131. The rotating plate 131 is rotatably installed on the top wall of the device body 1, and a limiting column 132 is fixed at one end of the top wall of the rotating plate 131; A limiting frame 133 is sleeved outside the limiting column 132; The side wall of the limiting frame 133 is fixed to the L-shaped push plate 135 through a connecting rod 134; One end of the L-shaped push plate 135 extends into the feed frame 9.

[0025] The power shaft at the top of the dual-axis motor 12 passes through the top wall of the device body 1 through a bearing and is fixedly connected to one end of the bottom wall of the rotating plate 131.

[0026] The feeding frame 9 includes a frame body 91, a partition 92 is fixed between the inner walls of the frame body 91, and a placement groove 93 matching with the L-shaped push plate 135 is formed on the left side of the frame body 91.

[0027] In this embodiment, the provided cleaning component 13 can, under the drive of the dual-axis motor 12, push the slag remaining on the filter plate 10 into the slag dropping groove 6 to prevent the slag from blocking the filter plate 10. In the initial state, the right end of the L-shaped push plate 135 is located in the placement groove 93. When the dual-axis motor 12 works, it drives the rotating plate 131 to rotate. During the rotation of the rotating plate 131, the L-shaped push plate 135 is driven to move left and right reciprocally through the limit post 132, the limit frame 133 and the connecting rod 134. When the L-shaped push plate 135 moves to the right, its vertical plate can push the slag on the surface of the filter plate 10 into the slag dropping groove 6 on the right. When the L-shaped push plate 135 moves to the left, under the action of the frame body 91, the wastewater poured on the top wall of the L-shaped push plate 135 can be scraped and dropped onto the filter plate 10, ensuring that the filter plate 10 can always maintain its filtering function.

[0028] Embodiment 3 As Figure 5 shown, based on the same concept as in the above Embodiment 1, this embodiment also proposes: The stirring component 14 includes a rotating shaft 141, the rotating shaft 141 is rotatably installed between the upper and lower walls of the stirring chamber 2, a plurality of fixed shafts 142 are symmetrically fixed on both the upper and lower parts of the rotating shaft 141, and a plurality of rotating shafts 143 are symmetrically and rotatably installed in the middle of the rotating shaft 141; Turning plates 144 are symmetrically fixed on the shaft bodies of the dry rotating shafts 143, and gears 145 are fixed at the ends of the dry rotating shafts 143 far from the rotating shaft 141; A toothed ring 146 is fixed on the inner wall of the stirring chamber 2; The gears 145 are all meshed with the toothed ring 146.

[0029] The power shaft at the bottom of the dual-axis motor 12 passes through the top wall of the stirring chamber 2 through a bearing and is fixedly connected to the top end of the rotating shaft 141.

[0030] In this embodiment, the provided stirring component 14 can fully mix the wastewater and the wastewater treatment liquid medicine under the drive of the dual-axis motor 12, and its mixing efficiency is high. When the stirring component 14 works, the dual-axis motor 12 drives the rotating shaft 141 to rotate. During the rotation of the rotating shaft 141, the fixed shafts 142 and the rotating shafts 143 are driven to rotate to mix the wastewater and the liquid medicine. At the same time, during the rotation of the rotating shaft 143, it can rotate self under the action of the gears 145 and the toothed ring 146, driving the turning plates 144 to rotate, thereby turning the wastewater and the liquid medicine in the stirring chamber 2 up and down, improving the mixing effect and reducing the mixing time.

[0031] Example 4 As Figures 2 to 3 and Figures 7 to 8 shown, based on the same concept as in the above Example 1, this example also proposes: The extrusion assembly 18 includes a mounting frame 181 fixed to the top wall of the feeding frame 9, and two electric hydraulic cylinders 182 are symmetrically fixed on the mounting frame 181; The movable ends at the bottoms of the two electric hydraulic cylinders 182 both slide through the mounting frame 181 and are fixed to the same trapezoidal block 183; A housing 184 is slidably sleeved on the outer side of the bottom of the trapezoidal block 183; The housing 184 is fitted with the slag dropping groove 6. A plurality of springs 185 are fixed between the bottom wall of the inner cavity of the housing 184 and the bottom wall of the trapezoidal block 183, and a movable column 186 is fixed at the center of the bottom wall of the housing 184; An installation groove 187 is formed at the center of the bottom wall of the trapezoidal block 183, and a control switch 188 is fixed to the top wall of the installation groove 187.

[0032] The material receiving assembly 22 includes a collection box 221. Rollers 222 are installed at the four corners of the bottom wall of the collection box 221, and a handle 223 is fixed to the side wall of the collection box 221.

[0033] The blocking mechanism includes a sealing plate 19 rotatably installed between the inner walls of the storage groove 21. The sealing plate 19 is in contact with the bottom of the slag dropping groove 6, and an electric push rod 20 is rotatably installed between the bottom wall of the sealing plate 19 and the side wall of the storage groove 21.

[0034] In this embodiment, the provided extrusion assembly 18 can intermittently compress the slag in the slag dropping tank 6, remove the waste liquid in the slag, and the compressed slag is convenient for recycling. During the working process of the extrusion assembly 18, the electric hydraulic cylinder 182 intermittently drives the trapezoidal block 183 to move up and down. When the trapezoidal block 183 moves downward, it drives the outer shell 184 to move downward, thereby compressing the slag in the slag dropping tank 6 and removing the waste liquid. The setting of the trapezoidal block 183 enables the slag falling on its surface during the compression process to fall back into the slag dropping tank 6 when the trapezoidal block 183 moves upward. At the same time, as the waste slag falling into the slag dropping tank 6 accumulates, each time the trapezoidal block 183 moves downward, the height at which the outer shell 184 moves to the lowest position will continuously move upward under the action of the waste slag. When the movable column 186 triggers the control switch 188, it means that enough waste slag has been collected in the slag dropping tank 6. When the movable column 186 triggers the control switch 188, the control switch 188 controls the double-shaft motor 12 and the electric hydraulic cylinder 182 to stop operating. At this time, the addition of waste liquid into the feeding frame 9 is stopped. The control switch 188 simultaneously controls the electric push rod 20 to contract. During the contraction of the electric push rod 20, it drives the sealing plate 19 to flip. At this time, the compressed material falls into the collection box 221 through the bottom end of the slag dropping tank 6 for collection. Then, the electric push rod 20 is reset through an external switch, driving the sealing plate 19 to block the bottom end of the slag dropping tank 6, and controlling the double-shaft motor 12 and the electric hydraulic cylinder 182 to work again for a new round of wastewater treatment.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
