Description

Technical Field

[0001] The invention relates to the technical field of dehydrating agent production, in particular to a composite sludge dehydrating agent prepared by using organic waste acid and a production system thereof. Background Art

[0002] Composite sludge dewatering agent is an innovative chemical agent. It is usually made by combining organic waste acid with a variety of raw materials through a complex process. Its ingredients contain specially treated wood powder, which undergoes a series of reactions such as alkalization under the action of sodium hydroxide. It also incorporates substances such as cationic polyacrylamide that help flocculation and natural bamboo charcoal particles with adsorption function. This dewatering agent plays a key role in sludge treatment. It can effectively separate the water in the sludge through various mechanisms such as flocculation and adsorption, significantly improve the solid-liquid separation efficiency of the sludge, reduce the water content of the sludge, and absorb the odor emitted by the sludge during the dehydration process, reducing the adverse effects on the environment. It has good dehydration performance and can meet environmental protection needs to a certain extent. It provides an efficient and relatively environmentally friendly solution for the sludge treatment field and has broad application prospects in sewage treatment plants, industrial wastewater treatment and other related fields.

[0003] In the process of producing the dehydrating agent, since a variety of raw materials need to be mixed and epichlorohydrin needs to be slowly added dropwise, the epichlorohydrin will be placed on the upper layer of the sheet by the dropwise addition.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention sets an etherification unit, and the baffle will not cover the gap one at a certain time. When the baffle does not cover the gap one, epichlorohydrin will flow out from the dripping port through the gap one, and slowly drip into the heating pot in the form of water droplets, and react with diethylenetriamine and concentrated hydrochloric acid. In this way, the speed and amount of dripping epichlorohydrin can be strictly controlled according to the progress of the reaction, avoiding the situation that the dripping acceleration is too fast, which may cause a violent reaction or even a dangerous situation, and if the dripping acceleration is too slow, it may affect the reaction efficiency.

During the rotation of the rotating shaft 1, dripping epichlorohydrin may enter the inlet, and then enter the interior of the stirring rod. As the epichlorohydrin accumulates in the stirring rod, the weight reaches a certain amount, which causes the sliding block to compress the telescopic spring, thereby driving the hook plate 1 to pull the hook plate 2, thereby causing the sealing plate to rotate, and ensuring that the epichlorohydrin can also come into contact with the bottom of the liquid and react.

[0017] 3. The present invention is provided with a flipping mechanism. When the telescopic rod moves downward, the containing plate will drive the wood powder on the water surface to move toward the bottom of the liquid. At the same time, the servo motor 2 will drive the beaker to rotate, thereby causing a certain amount of rotation and mixing of the liquid and the wood powder.

[0018] 4. The present invention is provided with a flipping mechanism. After a certain degree of mixing, the wood powder will gradually merge with the liquid and flow through the circular hole at the bottom of the holding plate to the top of the holding plate. After that, the two electromagnetic blocks will generate magnetic force in turn and cause the holding plate to rotate 180 degrees. After that, the telescopic rod will move downward again until the mixture of wood powder and liquid can all pass through the circular hole. During the downward movement, the scratch ring will also scratch the wood powder attached to the beaker and cause it to detach from the beaker wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0033] Example 1, using Figure 1-Figure 12 A composite sludge dehydrating agent prepared by using organic waste acid and a production system thereof according to one embodiment of the present invention are described as follows.

[0034] The invention discloses a composite sludge dehydrating agent prepared by using organic waste acid, and the raw materials thereof include: 30-60 parts of diethylenetriamine, 60-180 parts of concentrated hydrochloric acid, 75-125 parts of epichlorohydrin, 100-200 parts of wood flour, 50-100 parts of sodium hydroxide, 30-50 parts of cationic polyacrylamide, 50-100 parts of natural bamboo charcoal particles and appropriate amount of purified water.

[0035] like Figure 1-Figure 2 As shown, a production system for preparing a composite sludge dehydrating agent from organic waste acid comprises: a bottom plate 1, a support column 2 is fixedly connected to the top of the bottom plate 1, an operating table 3 is fixedly connected to the top of the support column 2, an etherification unit 4 is fixedly connected to the top of the bottom plate 1, an air pipe 5 is fixedly connected to the top of the etherification unit 4, a purification device 6 is fixedly connected to the end of the air pipe 5 away from the etherification unit 4, the bottom of the purification device 6 is fixedly connected to the top of the bottom plate 1, a liquid pump 7 is fixedly connected to the outer surface of the etherification unit 4, an end of the liquid pump 7 away from the etherification unit 4 is fixedly connected to the alkalization unit 8, and the bottom of the alkalization unit 8 is fixedly connected to the top of the bottom plate 1.

[0036] When the present invention is working, the staff controls the whole equipment through the operating table 3. After adding a proper amount of raw materials to the etherification unit 4, the water pump will extract the etherification agent in the upper layer and flow it into the alkalization unit 8. The purification device 6 will also adsorb the waste gas generated by the etherification. After that, the alkalization unit 8 will mix and stir some raw materials such as wood powder with the etherification agent to finally form a dehydrating agent.

[0037] like Figure 4-Figure 5As shown, the etherification unit 4 includes a support base 41, a heating device 42 is fixedly connected to the top of the support base 41, a heating pot 43 is fixedly connected to the top of the heating device 42, a support frame 44 is symmetrically arranged on the outer surface of the heating pot 43, a pouring inlet 45 is fixedly connected to the outer surface of the heating pot 43, a liquid outlet pipe 46 is fixedly connected to the side of the heating pot 43 close to the liquid pump 7, a top cover 47 is fixedly connected to the top of the heating pot 43, a stirring mechanism 48 is fixedly connected to the inner wall of the top cover 47, and a liquid containing plate 49 is fixedly connected to the inner wall of the heating pot 43.

[0038] First, 30 to 60 parts of diethylenetriamine and 60 to 180 parts of concentrated hydrochloric acid are added into the heating pot 43 through the pouring inlet, and then 75 to 125 parts of epichlorohydrin are added through the pouring inlet 487. At the same time, the heating device 42 will increase the temperature of the heating pot 43.

[0039] The bottom of the support seat 41 is fixedly connected to the top of the base plate 1 , and the bottom of the support frame 44 is fixedly connected to the top of the base plate 1 .

[0040] like Figure 5-Figure 6 As shown, the stirring mechanism 48 includes a servo motor 481, the output end of the servo motor 481 is fixedly connected to a rotating shaft 482, the top of the rotating shaft 482 is fixedly connected to a support ring 483, the bottom of the support ring 483 is fixedly connected to a support rod 484, the bottom of the support rod 484 is fixedly connected to a baffle 485, the bottom of the baffle 485 is slidably connected to the top of a liquid holding plate 49, the outer surface of the liquid holding plate 49 is provided with a notch 486, the bottom of the notch 486 is fixedly connected to a drip port 488, the outer surface of the liquid holding plate 49 is fixedly connected to a pouring port 487, and the bottom of the rotating shaft 482 is evenly provided with liquid stirring units 489.

[0041] The servo motor 481 will first drive the rotating shaft 482 to rotate at a certain efficiency, and then drive the baffle 485 to rotate, so that the baffle 485 does not cover the gap 486 at a certain time. When the baffle 485 does not cover the gap 486, epichlorohydrin will flow out from the dripping port 488 through the gap 486, and slowly drip into the heating pot 43 in the form of water droplets, and react with diethylenetriamine and concentrated hydrochloric acid. In this way, the speed and amount of dripping epichlorohydrin can be strictly controlled according to the progress of the reaction, avoiding the situation where the dripping acceleration is too fast, which may cause a violent reaction or even a danger, and if the dripping acceleration is too slow, it may affect the reaction efficiency.

[0042] like Figure 7-Figure 9As shown, the liquid stirring unit 489 includes a stirring rod 4891, the top of which is evenly provided with an inlet 4892, the bottom of which is provided with a notch 4893, the inner wall of the stirring rod 4891 is fixedly connected with a telescopic spring 4894, the top of the telescopic spring 4894 is fixedly connected with a sliding block 4895, the top of the sliding block 4895 is fixedly connected with a hook plate 1 4896, the outer surface of the notch 2 4893 is rotatably connected with a sealing plate 4897, the outer surface of the sealing plate 4897 is fixedly connected with a hook plate 2 4898, and the outer surface of the hook plate 2 4898 is abutted against the top of the hook plate 1 4896.

[0043] As the shaft 482 rotates, the stirring rod 4891 will also be driven to rotate, thereby properly stirring the mixed diethylenetriamine, concentrated hydrochloric acid and epichlorohydrin. However, due to the different densities of the three, the dripping epichlorohydrin may be in the upper layer of the page and cannot be mixed with the other two. During the rotation of the shaft 482, the dripping epichlorohydrin may enter the inlet 4892 and then enter the interior of the stirring rod 4891. As the epichlorohydrin accumulates in the stirring rod 4891, when the weight reaches a certain amount, the sliding block 4895 will compress the telescopic spring 4894, thereby driving the hook plate 1 4896 to pull the hook plate 2 4898, thereby causing the sealing plate 4897 to rotate, and ensuring that the epichlorohydrin can also come into contact with the bottom of the liquid and react, thereby ensuring sufficient contact between the three. After continuing to drip for 2 hours and standing for a period of time, an etherifying agent will form on the upper layer.

[0044] The top of the servo motor 481 is fixedly connected to the inner wall of the top cover 47, and the top of the stirring rod 4891 is fixedly connected to the outer surface of the rotating shaft 482.

[0045] The specific workflow is as follows:

[0046] During operation, 30 to 60 parts of diethylenetriamine and 60 to 180 parts of concentrated hydrochloric acid are first added into the heating pot 43 through the pouring inlet, and then 75 to 125 parts of epichlorohydrin are added through the pouring inlet 487. The servo motor 481 first drives the rotating shaft 482 to rotate at a certain efficiency, and then drives the baffle 485 to rotate, so that the baffle 485 does not block the gap 486 at a certain time. When the baffle 485 does not block the gap 486, epichlorohydrin will flow out from the dripping port 488 through the gap 486, and slowly drip into the heating pot 43 in the form of water droplets, and react with the diethylenetriamine and concentrated hydrochloric acid. At the same time, as the rotating shaft 482 rotates, the stirring rod 4891 will also be driven to rotate. However, due to the different densities of the three, the dripping epichlorohydrin may be on the upper layer of the page and cannot be mixed with the other two. During the rotation of the rotating shaft 482, the dripping epichlorohydrin may enter the inlet 4892 and then enter the interior of the stirring rod 4891. As the epichlorohydrin accumulates in the stirring rod 4891, when the weight reaches a certain amount, the sliding block 4895 will compress the telescopic spring 4894, thereby driving the hook plate 1 4896 to pull the hook plate 2 4898, thereby causing the sealing plate 4897 to rotate and ensuring that the epichlorohydrin can also come into contact with the bottom of the liquid and react.

[0047] Example 2, using Figure 1-Figure 12 A composite sludge dehydrating agent prepared by using organic waste acid and a production system thereof according to one embodiment of the present invention are described as follows.

[0048] like Figure 10-11 As shown, on the basis of Example 1, the alkalization unit 8 includes a support seat 81, the inner wall of the support seat 81 is fixedly connected to a servo motor 82, the top of the support seat 81 is fixedly connected to a water bath 83, the top of the water bath 83 is symmetrically provided with a support rod 84, the top of the support rod 84 is fixedly connected to a support plate 85, the bottom of the support plate 85 is fixedly connected to a telescopic rod 87, the bottom of the support plate 85 is symmetrically provided with an electromagnetic block 86, the bottom of the telescopic rod 87 is fixedly connected to a flipping mechanism 88, the end of the water bath 83 close to the liquid pump 7 is fixedly connected to a liquid inlet 89, the outer surface of the water bath 83 is fixedly connected to a water outlet 812, the output end of the servo motor 82 is fixedly connected to a rotating shaft 810, and the top of the rotating shaft 810 is fixedly connected to a beaker 811.

[0049] The etherifying agent is pumped into the beaker 811 through the liquid pump 7, and then 100 to 200 parts of wood powder are taken into the beaker 811, and an appropriate amount of anhydrous ethanol is added. The mixture is stirred evenly at room temperature to make the wood powder completely dispersed without agglomeration. 50 to 100 parts of sodium hydroxide are weighed and completely dissolved and poured into the beaker 811. Water is added to the water bath 83 and the temperature is increased. The turning mechanism 88 then turns the wood powder for 2 hours to achieve a fully mixed effect.

[0050] like Fig.12 The flipping mechanism 88 includes a support block 881, and a support rod 3 882 is symmetrically arranged on the outer surface of the support block 881. The bottom of the support rod 3 882 is rotatably connected to a holding plate 883, and the outer surface of the holding plate 883 is evenly provided with circular holes 884. The top of the holding plate 883 is symmetrically provided with magnetic blocks 886, and the outer surface of the holding plate 883 is fixedly connected with a scratch ring 885.

[0051] During the two hours of water bath heating and stirring, since the wood powder always floats on the water surface at the beginning and has strong adhesion after contacting water, the wood powder will adhere to the beaker 811, and the telescopic rod 87 will move up and down. When moving downward, the holding plate 883 will drive the wood powder on the water surface to move toward the bottom of the liquid. At the same time, the servo motor 82 will drive the beaker 811 to rotate, thereby causing a certain amount of rotation and mixing of the liquid and the wood powder. After mixing to a certain extent, the wood powder will gradually merge with the liquid and flow into the top of the holding plate 883 through the circular hole 884 at the bottom of the holding plate 883. As the telescopic rod 87 moves downward, the distance between the holding plate 883 and the electromagnetic block 86 becomes closer, and then the two electromagnetic blocks 86 will generate magnetic force in turn and generate attraction and repulsion forces on the two magnetic blocks 886 respectively, thereby causing the holding plate 883 to rotate 180 degrees. Then the telescopic rod 87 will move downward again and push the wood powder to move downward again to mix with the liquid until the mixture of wood powder and liquid can all pass through the circular hole 884. During the downward movement, the scratch ring 885 will also scratch the wood powder attached to the beaker 811 and make it detach from the wall of the beaker 811.

[0052] Afterwards, the heated water flows out through the water outlet 812 to make the beaker 811 reach room temperature, 30 to 50 parts of cationic polyacrylamide and appropriate amount of water are added for thickening, and stirred at room temperature to make it uniform. The obtained product is allowed to stand and cool to obtain a brown viscous cationic dehydrating agent.

[0053] Finally, add 50 to 100 parts of natural bamboo charcoal particles, stir and mix thoroughly, so that the bamboo charcoal particles are evenly mixed in the dehydrating agent to obtain the final finished dehydrating agent. Adding natural bamboo charcoal particles can absorb the odor inside the sludge during dehydration, avoid the spread of odor, and improve the working environment.

[0054] The bottom of the support seat 81 is fixedly connected to the top of the bottom plate 1 , the top of the support block 881 is fixedly connected to the bottom of the telescopic rod 87 , and the outer surface of the scratch ring 885 is in contact with the inner wall of the beaker 811 .

[0055] The specific workflow is as follows:

[0056] During operation, the etherifying agent is pumped into the beaker 811 through the liquid pump 7, and then 100 to 200 parts of wood powder are taken into the beaker 811, and an appropriate amount of anhydrous ethanol is added. The mixture is stirred evenly at room temperature to make the wood powder completely dispersed without lumps. 50 to 100 parts of sodium hydroxide are weighed and completely dissolved and poured into the beaker 811. Water is added to the water bath 83 and the temperature is increased. When the telescopic rod 87 moves downward, the holding plate 883 will drive the wood powder on the water surface to move toward the bottom of the liquid. At the same time, the servo motor 82 will drive the beaker 811 to rotate, thereby causing a certain amount of rotation and mixing of the liquid and the wood powder. After mixing to a certain extent, the wood powder will gradually merge with the liquid and flow from the bottom of the holding plate 883 through the circular hole 884 to the top of the holding plate 883. As the telescopic rod 87 moves downward, The distance between the holding plate 883 and the electromagnetic block 86 becomes closer, and then the two electromagnetic blocks 86 will generate magnetic force in turn and generate adsorption and repulsion forces on the two magnetic blocks 886 respectively, thereby causing the holding plate 883 to rotate 180 degrees. Then the telescopic rod 87 will move downward again and push the wood powder to move downward again to mix with the liquid until the mixture of the wood powder and the liquid can all pass through the circular hole 884. During the downward movement, the scratching ring 885 will also scratch the wood powder attached to the beaker 811 and make it detach from the wall of the beaker 811. 30 to 50 parts of cationic polyacrylamide and an appropriate amount of water are added to thicken the mixture, and stirred at room temperature to make it uniform. Finally, 50 to 100 parts of natural bamboo charcoal particles are added, and the mixture is fully stirred and mixed so that the bamboo charcoal particles are evenly mixed in the dehydrating agent to obtain the final finished dehydrating agent.

[0057] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
