Description

Technical Field

[0001] This utility model relates to the field of sludge solidification equipment, and in particular to a test device for co-solidifying waste sludge from industrial waste residue. Background Technology

[0002] Chemical solidification is one of the effective methods for large-scale disposal of dredged sludge. It involves adding a solidifying agent to the sludge, causing a series of physicochemical reactions between the water, clay minerals, and the solidifying agent to improve the engineering properties of the sludge, increase soil strength, and achieve resource utilization. However, this requires a large amount of solidifying agent to meet the solidification requirements of the sludge. Therefore, dredged sludge often incorporates industrial waste residue in addition to the solidifying agent. The chemical components in the industrial waste residue can effectively dehydrate and solidify the sludge. A sludge solidification device, such as the Chinese invention patent with publication number CN115583772A, discloses a device including a tank. Four legs are fixedly connected to the bottom of the outer wall of the tank, four feeding hoppers are fixedly connected to the top of the tank, two discharge pipes are fixedly connected to the bottom of the tank, a guide ring is fixedly connected to the bottom of the inner wall of the tank, and a drive mechanism is installed in the middle of the tank. The drive mechanism provides power for the operation of the device and extracts external gas into the tank. When using this type of equipment, the proportions of curing agent and industrial waste residue need to be manually mixed, then put into the tank and stirred evenly. Finally, it is put into the sludge and the curing degree is tested after a period of time. However, for the test, multiple different control groups are needed for comparison. This type of device only achieves the mixing of materials and cannot set up multiple materials with different proportions for control tests. Utility Model Content

[0003] The purpose of this invention is to provide an experimental device for co-solidifying industrial waste residue and regulating waste sludge. This invention can set up multiple groups of solidified materials with different proportions to obtain multiple groups of sludge samples containing different chemical components, facilitating experimental comparison.

[0006] In the aforementioned experimental device for co-solidification of industrial waste residue and waste sludge, the material control component includes a set of opening and closing fasteners hinged to the discharge end of the hopper. A control cylinder is provided on the side of one side of the opening and closing fastener, and the extended end of the control cylinder is hinged to the side of the opening and closing fastener on the other side.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. In this utility model, the single feed pipe corresponds to a type of powdered industrial waste residue. Multiple types of industrial waste residue powder are fed into the waste residue mixing component through the feed pipe. The waste residue mixing component mixes the various powdered industrial waste residues with a solidifying agent to generate a solidified material with a specific ratio. This material then flows into the hopper. Through precise control of the material body control components, the material is fed into the material compartment of the distribution box. Following this process, different material compartments can obtain solidified materials with different ratios. The material in the material compartment enters the mixing vessel through the cylinder outlet, where it is thoroughly mixed with sludge and finally flows into the receiving box, forming a set of sludge samples. Sludge is then added back into the mixing vessel, and the distribution box is rotated to add another ratio of solidified material, resulting in a new set of sludge samples. Multiple sets of sludge samples in the receiving box can be directly used for testing and comparison. By setting multiple sets of solidified materials with different ratios, multiple sets of sludge samples containing different chemical components are obtained, facilitating experimental comparison.

[0013] 3. The receiving box is equipped with multiple chambers, each chamber is used to store a set of sludge samples, which greatly facilitates the comparison and testing of different samples and further optimizes the test process. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example: Experimental device for co-solidification of industrial waste residue and waste sludge, including main support 1, as shown in the attached figure. Figure 1As shown, a mixing vessel 2 is installed on the main support 1, and a mixing component is installed inside the mixing vessel to uniformly mix solidified materials with sludge in different proportions. A batching support 3 is set on the side of the main support 1, and a hopper 4 is installed on the batching support 3. A waste residue mixing component 5 is installed on the hopper 4. Multiple feed pipes 6 for feeding industrial waste residue powder are installed on one side of the waste residue mixing component 5. The feed pipes are equipped with solenoid valves to control the dosage of industrial waste residue powder. There are many types of industrial waste residue, such as blast furnace slag, fly ash, carbide slag, and desulfurization gypsum. In order to facilitate the mixing of these industrial waste residues into the sludge, the industrial waste residues need to be ground into powder. A material control component 7 is installed at the discharge end of the hopper 4. The material control component 7 includes a set of opening and closing fasteners 19 hinged to the discharge end of the hopper 4, as shown in the attached figure. Figure 3 As shown, a control cylinder 20 is installed on the side of the opening and closing fastener 19 on one side. The extended end of the control cylinder 20 is hinged to the side of the opening and closing fastener 19 on the other side. By controlling the extension or retraction of the extended end of the control cylinder, the distance between the opening and closing fasteners on both sides can be controlled, thereby controlling the discharge amount of the solidified material. This effectively controls the discharge amount of the solidified material and ensures that the material falls stably into the material hopper by controlling the distance between the opening and closing fasteners on both sides. The dispensing bracket 3 is provided with a limiting stop bar 21. The end of the limiting stop bar is provided with a baffle 22 for abutting against the opening and closing fastener 19. The distance between the opening and closing fasteners on both sides is limited by the baffle, preventing the distance between the opening and closing fasteners on both sides from being too large. A positioning bracket 8 is installed on the front side of the dispensing bracket 3. A cylinder 9 is installed on the positioning bracket 8. A dispensing box 10 connected to the motor is installed inside the cylinder 9. Figure 4 As shown, the material distribution box 10 has multiple material compartments 11, as attached. Figure 5 As shown, the number of material hoppers can be set according to experimental requirements. The distribution box is a cylindrical structure, with material hoppers evenly distributed on the circumference of the distribution box. The distribution box is connected to a motor to realize the rotation of the distribution box. When the material hopper rotates to the inlet of the cylinder, material is fed in; when the material hopper rotates to the outlet of the cylinder, material is discharged. The outlet end of the cylinder 9 is provided with a slide 23 corresponding to the inlet of the mixing vessel 2. The slide allows the material to flow smoothly and stably into the mixing vessel. The material hopper contains pre-mixed solidified material, the difference being the different dosage of industrial waste residue components. The opening end of the material hopper 11 corresponds to the material control component 7 through the inlet of the cylinder 9, and the outlet end of the cylinder 9 corresponds to the inlet of the mixing vessel 2. A receiving box 12 is installed below the outlet end of the mixing vessel 2. The receiving box 12 includes a box body 24 located below the outlet end of the mixing vessel 2, as shown in the attached figure. Figure 6As shown, the box body 24 has multiple chambers 25 for holding the proportioned sludge material. The bottom of the box body 24 is equipped with a sliding rail 26 and a translation cylinder 27 for moving the box body 24. Each chamber is used to store a set of sludge samples, greatly facilitating the comparative testing of different samples and further optimizing the experimental process. The translation cylinder can move the box body, aligning different chamber positions with the discharge port of the mixing vessel, facilitating material discharge.

[0023] The waste mixing assembly 5 includes a box 13 disposed on the upper part of the hopper 4, as shown in the attached figure. Figure 2 As shown, a motor 14 is installed on one side of the box 13, and the extended end of the motor 14 is connected to an auger shaft 15 that extends into the box 13; a cylinder bracket 16 is installed on the side of the batching support 3, and a transverse cylinder 17 is provided on the cylinder bracket 16. The extended end of the transverse cylinder 17 is connected to a sealing plate 18 for opening the bottom of the box 13. The waste residue mixing component mainly mixes different types of industrial waste residue and curing agent. In this embodiment, the curing agent can be cement or lime. The sealing plate controls the opening of the bottom of the box to realize the discharge of the mixed and cured material.

[0024] The working principle of this utility model is as follows: The waste residue powder enters the housing 13 of the waste residue mixing component 5 through the feed pipe 6. The motor 14 inside the housing 13 drives the auger shaft 15 to rotate, fully mixing the industrial waste residue powder with the curing agent (cement or lime). After mixing, the horizontal cylinder 17 on the cylinder support 16 next to the batching support 3 extends, causing the sealing plate 18 to open the bottom of the housing 13. The mixed cured material falls into the hopper 4, and the material control component 7 at the discharge end of the hopper 4 begins to work. Subsequently, the extension or retraction of the control cylinder 20 drives the opening and closing fasteners 19 on both sides to change the spacing, thereby precisely controlling the discharge amount of the cured material. After precise control, the cured material falls into the material compartment 11 of the distribution box 10. Since the distribution box 10 is connected to the motor 14, the motor 14 drives the distribution box 10 to rotate, allowing different materials to flow smoothly. The chambers 11 are aligned with the inlet of the cylinder 9 to feed the material. Each chamber 11 can be filled with solidified material in different proportions. The distribution box 10 rotates so that the chambers 11 containing solidified material are aligned with the outlet of the cylinder 9. The material smoothly enters the mixing vessel 2 through the slide 23. The mixing components in the mixing vessel 2 fully mix the solidified material with the sludge. The sludge flows out from the outlet of the mixing vessel 2 and falls into the chamber 25 of the receiving box 12. The translation cylinder 27 at the bottom of the receiving box 12 pushes the box 24 to move, so that different chambers 25 are aligned with the outlet of the mixing vessel 2 in sequence to collect sludge samples under the action of solidified material in different proportions. Each chamber 25 stores a set of sludge samples, which is convenient for subsequent comparative testing of different samples. This helps to study the effect of different proportions of solidified material on sludge solidification and obtain the optimal proportion of solidified material.
