Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment, and in particular to a sludge stirring device for preparing nutrient soil. Background Art

[0002] Nutrient soil is a soil or culture medium rich in nutrients required for plant growth. It is a specially prepared soil or soil substitute to provide the nutrients required by plants during their growth. The main function of nutrient soil is to provide the nutrients required by plants and promote their normal growth and development. At present, nutrient soil can be prepared from sludge, which is a mixture of solid waste and water produced during wastewater treatment. Although sludge contains certain organic matter and nutrients, there may be some problems in directly using untreated sludge, such as the presence of odor, pathogens, heavy metals and other pollutants. Therefore, when preparing nutrient soil, the sludge usually needs to be properly treated and improved. In the sludge treatment process, the filtered sludge needs to be introduced into the stirring equipment from the feed port of the stirring equipment and reaction reagents (such as oxidants, lime, sulfuric acid, flocculants, disinfectants, heavy metal stabilizers, etc.) need to be added for sufficient stirring to eliminate the odor of the sludge, adjust the pH value of the sludge, improve the properties of the sludge, degrade organic matter, remove heavy metals, etc. However, when the sludge is introduced into the stirring equipment, due to the small feed port, when the instantaneous sludge introduction amount is large, sludge accumulation is likely to occur at the feed port, causing the sludge to overflow from the feed port, thereby affecting the sludge introduction speed and reducing the stirring efficiency.

A plurality of stirring rods 9 are evenly and equidistantly fixed on each rotating shaft 8 along its length direction, and the rotation paths of the stirring rods 9 on the two rotating shafts 8 are staggered with each other (such as Figure 4 and Figure 5As shown), this arrangement enables the stirring rods 9 on the two rotating shafts 8 to fully stir the sludge introduced into the mixing drum and the added reaction reagents, thereby enhancing the stirring efficiency. In addition, a triangular guide block 18 is fixedly provided at the bottom of the horizontal mixing drum 1 along its length direction, and the guide slopes on both sides of the triangular guide block 18 correspond to the rotation paths of the two stirring rods 9 on the two rotating shafts 8 respectively. The arrangement of the triangular guide block 18 can guide the sludge located in the dead corner of the rotation paths of the two stirring rods 9 in the middle of the bottom surface of the mixing drum to the two rotation paths, thereby further improving the stirring efficiency; a transmission box 2 is fixedly provided on one side of the horizontal mixing drum 1, and a transmission member is provided in the transmission box 2, which is a sprocket 16 and a chain 17. One end of the two rotating shafts 8 passes through one side of the horizontal mixing drum 1 and is fixedly provided with a sprocket 16. The two sprockets 16 are connected by the chain 17 for transmission. A driving motor 10 is installed on the side, and the output shaft of the driving motor 10 is fixedly connected to the end of one of the rotating shafts 8. In addition, the transmission member can also use two gears to transmit to each other. Specifically, the two gears are respectively installed on one end of the two rotating shafts 8 and the two gears are meshed with each other; a discharge valve pipe 11 is connected to the lower part of the other side of the horizontal mixing drum 1. The discharge valve pipe 11 is provided with two and corresponds to the two sides of the triangular guide block 18 respectively, so as to facilitate the sludge on both sides of the triangular guide block 18 to be discharged. A valve is provided on the discharge valve pipe 11 for switch setting, and the discharge valve pipe 11 can be externally connected to a mud pump to facilitate the sludge in the horizontal mixing drum 1 to be extracted; a feed barrel 3 is fixedly provided on the top plate of the horizontal mixing drum 1, and the interior of the feed barrel 3 is connected to the interior of the horizontal mixing drum 1, and the internal length setting of the feed barrel 3 is consistent with the internal length setting of the horizontal mixing drum 1 (such as Figure 3As shown in the figure, a rotating shaft 12 is provided in the feeding barrel 3 along its length direction, a spiral blade 13 is fixed on the rotating shaft 12, a rotating motor 14 is installed on one side of the feeding barrel 3, and the output shaft of the rotating motor 14 is fixedly connected to one end of the rotating shaft 12, a feeding hopper 4 is fixedly provided on the top of the feeding barrel 3, and the opening of the feeding hopper 4 is a flared structure to facilitate the introduction of sludge, and the feeding hopper 4 is connected to the inside of the feeding barrel 3. In the design, the feeding barrel 3 connected to the top of the horizontal mixing drum 1 and the spiral blade 13 provided inside the feeding barrel 3 are used to introduce the sludge from the feeding hopper 4 into the horizontal mixing drum. 1, the sludge first enters the feed barrel 3 during the internal process. Since the feed barrel 3 is connected to the horizontal mixing barrel 1 and the internal lengths of the two are consistent, when the instantaneous amount of sludge introduced at the feed hopper 4 is too large, the spiral blades 13 in the feed barrel 3 rotate as the rotating motor 14 drives the rotating shaft 12 to rotate, and then the sludge at the feed port is driven by the spiral blades 13 to flow along the length direction of the feed barrel 3 and introduced into the horizontal mixing barrel 1, and the sludge can be evenly introduced into the horizontal mixing barrel 1, avoiding the sludge from accumulating at the feed hopper 4, and improving the sludge introduction rate; in addition, the lower part of the cross section of the feed barrel 3 is a retracted structure (such as Figure 4 As shown), this design enables the sludge in the feed barrel 3 to be smoothly introduced into the horizontal mixing drum 1, and facilitates the spiral blades 13 to push the sludge along the length direction of the feed barrel 3 so that the sludge is evenly introduced into the horizontal mixing drum 1; the top of the horizontal mixing drum 1 is located on one side of the feed barrel 3 and is fixedly provided with a drug delivery tube 5 along its length direction, and the length setting of the drug delivery tube 5 is consistent with the length setting of the horizontal mixing drum 1 (as shown in FIG. Figure 6 As shown in the figure, the bottom of the drug delivery tube 5 is evenly and equidistantly connected with a plurality of drug outlet pipes 15 along its length direction, and the diameter of the drug outlet pipe 15 is smaller than the diameter of the drug delivery tube 5. The plurality of drug outlet pipes 15 all penetrate the top plate of the horizontal mixing drum 1 toward the inside of the horizontal mixing drum 1. The top of the drug delivery tube 5 is connected with a drug inlet hopper 6, and the opening of the drug inlet hopper 6 is a flared structure to facilitate the pouring of the reaction agent. In a specific implementation, the reaction agent is poured into the drug delivery tube 5 from the drug inlet hopper 6. Since the diameter of the drug outlet pipe 15 is smaller than the diameter of the drug delivery tube 5, the reaction agent can flow along the drug delivery tube 5 and then flow out from the plurality of drug outlet pipes 15 into the horizontal mixing drum 1, so that the reaction agent can be evenly added to the horizontal mixing drum 1 for stirring reaction with the sludge.

[0022] Working principle: When in use, start the rotating motor 14 and the driving motor 10, which respectively drive the rotating shaft 12 and the rotating shaft 1 8 to rotate, and then respectively drive the spiral blade 13 and the stirring rod 9 to rotate, and introduce the filtered sludge from the feed hopper 4 into the feed barrel 3, and the spiral blade 13 drives the sludge along the feed barrel 3 and evenly introduces it into the horizontal mixing drum 1, and pours the reaction agent from the drug feed hopper 6 into the drug delivery tube 5. Since the diameter of the drug outlet tube 15 is smaller than the diameter of the drug delivery tube 5, the reaction agent can flow along the drug delivery tube 5 and then flow out from multiple drug outlet tubes 15 into the horizontal mixing drum 1, so that the reaction agent can be evenly added to the horizontal mixing drum 1 to react with the sludge in stirring. When the stirring is completed, open the valve on the discharge valve tube 11 to discharge the sludge in the horizontal mixing drum 1.
