Description

Technical Field

[0001] This application relates to the field of sludge ceramsite production technology, specifically a mixing device for sludge ceramsite production. Background Technology

[0002] Sludge ceramsite is a lightweight building material made primarily from sludge through a specific process. During its manufacture, to improve its physicochemical properties, a mixing device is typically used to blend the sludge and additives, thereby enhancing the quality and performance of the ceramsite.

[0003] A search revealed, for example, a patent with publication number CN112808058A, which specifically discloses a sludge mixing device for manufacturing ceramsite. This patent uses a crusher to turn large granular dried sludge into powdered dried sludge, and then mixes the dried sludge and wetted sludge in a mixing chamber.

[0004] Most mixing devices do not strictly control the proportion of raw materials before mixing sludge. However, during the mixing process, due to different proportions of raw materials, the concentration of sludge ceramsite in the finished product may be too high or too low in some areas, which affects sintering and the performance of the finished product, and reduces the quality and stability of the ceramsite. Therefore, it is necessary to provide a mixing device for sludge ceramsite production to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-2As shown, this application provides a mixing device for sludge ceramsite production, including a base 1, a spiral mixer 11 fixedly installed on the upper end of the base 1, and a discharge pipe 111 connected to the lower end of the spiral mixer 11. The discharge pipe 111 is used to discharge the mixed sludge mixture.

[0033] Meanwhile, a discharge pipe 13 is connected to the upper end of one side of the spiral mixer 11. The upper end of the discharge pipe 13 is connected to a second hopper 14. A second weighing mechanism 3 is provided at the upper end of the second hopper 14. The second weighing mechanism 3 is used to weigh the additive to be mixed and to put the weighed additive into the second hopper 14, and then into the spiral mixer 11 along the discharge pipe 13.

[0034] To facilitate the addition of sludge to be mixed, a fixed frame 16 is fixedly installed on the upper end of the spiral mixer 11 on the side away from the feed pipe 13. A spiral conveyor 15 is fixedly installed on the upper end of the fixed frame 16, and the discharge end pipe of the spiral conveyor 15 is connected to the feed pipe 13.

[0035] Furthermore, a material box 17 is connected to the upper end of one side of the screw conveyor 15 via a pipe, and a first hopper 18 is connected to the upper end of the material box 17 via a pipe. Figure 2 As shown, the upper end of the first hopper 18 is provided with a first weighing mechanism 2. The first weighing mechanism 2 is used to weigh the sludge to be mixed. After weighing, the sludge enters the first hopper 18, and then enters the screw conveyor 15 along the material box 17. The screw conveyor 15 transports the sludge to the discharge pipe 13, and finally mixes it with the additives.

[0036] In this application, the first weighing mechanism 2 and the second weighing mechanism 3 have the same structure. For ease of understanding, the following description uses the first weighing mechanism 2 as an example. Specifically:

[0037] like Figures 2-3 As shown, the first weighing mechanism 2 has a storage cylinder 21. In order to fix the storage cylinder 21 and weigh it, multiple sets of columns 26 are fixedly installed on the upper surface of the first hopper 18. A top ring 27 is fixedly installed on the upper end of the column 26, and the storage cylinder 21 is disposed inside the top ring 27.

[0038] Meanwhile, multiple sets of fixed seats 23 are evenly fixedly installed on the outer side of the storage cylinder 21. A weighing sensor 24 is fixedly installed on the fixed seat 23. A connecting rod 25 is fixedly installed on the upper end of the weighing sensor 24. The connecting rod 25 is fixedly installed on the lower end of the top ring 27. In this application, an alarm light (not shown) is provided on one side of the weighing sensor 24. When the value of the weighing sensor 24 reaches the specified value, the alarm light will sound an alarm to remind the operator.

[0039] Furthermore, the weighing sensor 24 is suspended vertically, so the pulling force of the weighing sensor 24 on the storage cylinder 21 is parallel to the direction of the gravity of the storage cylinder 21, thereby weighing the material in the storage cylinder 21. It should be noted that since the storage cylinder 21 is located inside the top ring 27, horizontal swaying of the storage cylinder 21 is avoided, thus preventing it from affecting the measurement of the weighing sensor 24.

[0040] Furthermore, a feeding mechanism 22 is provided on both sides of the lower end of the storage cylinder 21. The feeding mechanism 22 has a fixing plate 221 fixedly installed on the outer wall of the storage cylinder 21. A drive cylinder 222 is hinged to the lower end of the fixing plate 221. The output shaft of the drive cylinder 222 is set downward, and a connecting seat 226 is fixedly installed on the output shaft. At the same time, two sets of protruding plates 223 are fixedly installed on the outer side of the bottom end of the storage cylinder 21. A fixing strip 224 is hinged to the outer end of the protruding plate 223. A baffle 225 is fixedly installed at the lower end of the fixing strip 224. The baffle 225 is set as a semi-circle.

[0041] A connecting plate 227 is also fixedly installed on the baffle 225. The connecting plate 227 is located between the fixing bars 224. The end of the connecting plate 227 away from the baffle 225 is hinged to the connecting seat 226. Therefore, when the drive cylinder 222 is started and extended outward, it can drive the connecting plate 227 and the baffle 225 to rotate along the convex plate 223 until the baffle 225 is located at the bottom of the storage cylinder 21. At this time, the two sets of feeding mechanisms 22 will completely close the bottom of the storage cylinder 21.

[0042] In this application, rubber pads are provided on the opposite surfaces of the baffle 225, thus ensuring the sealing performance of the baffle 225 when they are in contact.

[0043] It should be noted that the weighing sensor 24 and the drive cylinder 222 are controlled by a PLC program. When the weighing sensor 24 reaches the specified value, the alarm light will light up, the operator will stop feeding, and then the drive cylinder 222 will start to open the baffle 225 to discharge the material.

[0044] In summary: When mixing the materials required for the production of sludge ceramsite, the operator adds the sludge to be mixed into the first weighing mechanism 2. After reaching a certain weight, the addition is stopped. Then, the cylinder 222 is driven to open the baffle 225 so that the sludge enters the hopper 17 and is conveyed into the feed pipe 13 by the screw conveyor 15.

[0045] Simultaneously, the operator adds the required additives to the second weighing mechanism 3. Similarly, once a certain weight is reached, the addition is stopped, and then the second weighing mechanism 3 is opened to allow the additives to enter the feed pipe 13. Subsequently, the sludge and additives enter the spiral mixer 11 for mixing. After mixing, the mixture is discharged out through the discharge pipe 111. Therefore, when mixing sludge, the proportion of raw materials is ensured, preventing the finished sludge ceramsite from having local concentrations that are too high or too low, ensuring the performance of sintering and the finished product, and improving the quality and stability of the ceramsite.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
