Description

Technical Field

[0001] This application relates to the technical field of filter cartridges, and in particular to a discharge filter cartridge for a concrete low-temperature accelerator mixing tank. Background Technology

[0002] In the field of modern construction engineering, low-temperature concrete accelerators are key materials for ensuring the quality of concrete construction in low-temperature environments, making meticulous control of their production process particularly important. The filtration process after the material is discharged from the mixing tank directly affects product quality.

[0003] In related technologies, the discharge filter cylinder of a low-temperature concrete accelerator mixing tank generally adopts a filter screen structure with a fixed mesh diameter. Due to the complexity of the raw materials used in the production of low-temperature concrete accelerators, and the varying particle sizes of impurities mixed in the accelerator, the fixed-mesh filter screen is prone to clogging when faced with large-particle impurities or accelerator agglomeration. Once clogged, operators typically need to stop the entire filtration process and spend time disassembling and cleaning the filter screen, which not only consumes a significant amount of time and manpower but also leads to production interruption. Furthermore, the cleaning process reduces production efficiency. Utility Model Content

[0004] In order to reduce the decrease in the production efficiency of accelerator due to the cleaning process of the filter barrel mesh, this application provides a discharge filter barrel for a concrete low-temperature accelerator mixing tank.

[0005] The technical solution provided in this application for a discharge filter cylinder of a low-temperature concrete accelerator mixing tank is as follows:

[0006] A discharge filter cylinder for a low-temperature concrete accelerator mixing tank includes a filter cylinder body, an inlet pipe and an outlet pipe connected to the filter cylinder body, a pump body installed on the inlet pipe, a partition plate fixedly connected inside the filter cylinder body, a guide pipe fixedly connected to the partition plate, a first filter screen cylinder provided below the guide pipe, the first filter screen cylinder being coaxially arranged and connected to the guide pipe, a second filter screen cylinder provided on one side of the first filter screen cylinder, a moving mechanism for moving the first filter screen cylinder and the second filter screen cylinder between them, and an inspection port opened on the filter cylinder body above the second filter screen cylinder, with a cover installed at the inspection port.

[0007] By adopting the above technical solution, the coagulant entering the filter cylinder can enter the first filter screen cylinder through the feed pipe for filtration. After filtration, it is discharged from the filter cylinder through the discharge pipe. When the filter cylinder is clogged, the pump is turned off. Then, the first and second filter screen cylinders can be interchanged by controlling the moving mechanism. After that, the pump can be turned on again to quickly restore the filtration capacity of the filter cylinder. This saves the time of cleaning the filter cylinder during production and reduces the occurrence of reduced coagulant production efficiency due to the cleaning process of the filter screen. When the filter cylinder is idle, the impurities in the first filter screen cylinder can be cleaned through the inspection port. When the second filter screen cylinder is clogged, it can replace the first filter screen cylinder by the above method.

[0008] Optionally, the moving mechanism includes a rotating rod rotatably connected to the filter cylinder body, two support rods fixedly connected to the rotating rod, and a mounting ring fixedly connected to each support rod. The upper edges of the first filter cylinder and the second filter cylinder respectively abut against the mounting rings. The moving mechanism also includes a driving component for driving the rotating rod to rotate.

[0009] By adopting the above technical solution, the rotating rod can be driven by the driving component to rotate, thereby causing the mounting ring to rotate with the rotating rod, and thus quickly making the second filter cylinder and the first filter cylinder interlocked.

[0010] The moving mechanism further includes a fixing component for securing the first filter cylinder or the second filter cylinder to the mounting ring.

[0011] By adopting the above technical solution, the stability of the first or second filter cylinder on the mounting ring can be improved by fixing components.

[0012] Optionally, the driving component is configured as a drive motor, which is mounted on the filter cylinder, and the output shaft of the drive motor is coaxially arranged and fixedly connected to the rotating rod.

[0013] By adopting the above technical solution, the drive motor can be controlled to rotate, thereby causing the drive motor to drive the rotating rod to rotate, and thus quickly driving the rotating rod to rotate.

[0014] Optionally, the fixing component includes a plurality of fixing bolts, which are inserted into the first filter cylinder or the second filter cylinder, and the shank of the fixing bolt is threaded onto the mounting ring.

[0015] By adopting the above technical solution, the shank of the fixing bolt can be disengaged from the mounting ring by rotating the fixing bolt, thereby quickly removing the fixing of the first or second filter cylinder on the mounting ring.

[0016] Optionally, a rubber protective ring is fixedly connected to the lower end of the feed tube, and the rubber protective ring is arranged along the end face of the feed tube.

[0017] By adopting the above technical solution, the sealing between the upper part of the first filter cylinder and the upper part of the second filter cylinder and the feed pipe can be improved by protecting the rubber ring.

[0018] Optionally, two fixing bolts are provided on each of the mounting rings and located on both sides of the mounting ring respectively.

[0019] By adopting the above technical solution, two fixing bolts can stably fix the first or second filter screen on the mounting ring and facilitate disassembly.

[0020] Optionally, the fixing bolt is configured as a slotted bolt.

[0021] By adopting the above technical solution, the slotted bolts can facilitate the disassembly of the fixing bolts inside the filter cartridge.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. It can save the time of cleaning the filter cylinder during the production process, and reduce the occurrence of reduced coagulant production efficiency due to the cleaning process of the filter cylinder mesh. Then, when the filter cylinder is idle, the impurities in the first filter cylinder can be cleaned through the inspection port. Then, when the second filter cylinder is blocked, it can replace the first filter cylinder by the above method.

[0024] 2. The rotation can be achieved by controlling the drive motor, which in turn drives the rotating rod to rotate, thereby rapidly rotating the rotating rod.

[0025] 3. The fixing bolt can be rotated to disengage the bolt from the mounting ring, thereby quickly removing the first or second filter cylinder from the mounting ring. Attached Figure Description

[0030] An embodiment of this application is: a discharge filter cylinder for a concrete low-temperature accelerator mixing tank, as described above. Figure 1 and Figure 2 The system includes a filter cylinder 1, with a feed pipe 2 fixedly connected and connected to the upper part of the filter cylinder 1. A pump 21 for conveying coagulant into the filter cylinder 1 is installed on the feed pipe 2. A discharge pipe 3 is fixedly connected and connected to the lower part of the filter cylinder 1.

[0031] A partition plate 4 is fixedly connected inside the filter cylinder 1, and a guide pipe 5 is fixedly connected to the partition plate 4. The guide pipe 5 is coaxially arranged with the filter cylinder 1. A rubber protective ring 9 is fixedly connected to the lower end of the guide pipe 5, and the rubber protective ring 9 is arranged along the end face of the guide pipe 5.

[0032] A first filter cylinder 6 is located below the feed pipe 5, coaxially connected to and communicating with the feed pipe 5. A second filter cylinder 7 is located on one side of the first filter cylinder 6, coaxially connected to it. An inspection port 11 is provided on the filter cylinder body 1 above the second filter cylinder 7, and a cover 12 is installed at the inspection port 11. A moving mechanism 8 is provided between the first filter cylinder 6 and the second filter cylinder 7 to drive their movement.

[0033] The moving mechanism 8 includes a rotating rod 81 rotatably connected inside the filter cylinder 1. Two support rods 82 are fixedly connected to the rotating rod 81, and the two support rods 82 are located on the same straight line. Each support rod 82 is fixedly connected to a mounting ring 83. The upper edges of the first filter cylinder 6 and the second filter cylinder 7 respectively abut against the mounting rings 83.

[0034] The mounting ring 83 is provided with a fixing assembly 86 for fixing the first filter cylinder 6 or the second filter cylinder 7 onto the mounting ring 83. The fixing assembly 86 includes a plurality of fixing bolts 861. In this embodiment, to facilitate rotation of the fixing bolts 861, the fixing bolts 861 are configured as slotted bolts. In this embodiment, two fixing bolts 861 are provided on each mounting ring 83, and the two fixing bolts 861 are respectively located on both sides of the mounting ring 83. The fixing bolts 861 pass through the first filter cylinder 6 or the second filter cylinder 7, and the shank of the fixing bolt 861 is threadedly connected to the mounting ring 83.

[0035] Furthermore, by rotating the fixing bolt 861, the shank of the fixing bolt 861 can be disengaged from the mounting ring 83, thereby quickly removing the fixing of the first filter cylinder 6 or the second filter cylinder 7 on the mounting ring 83.

[0036] The moving mechanism 8 also includes a drive component 85 for rotating the rotating rod 81.

Therefore, by controlling the rotation of the drive motor, the drive motor can drive the rotating rod 81 to rotate, thereby rapidly rotating the rotating rod 81.

[0037] The implementation principle of this application is as follows: the coagulant from the previous process can be guided into the filter cylinder 1 through the pump body 21. The subsequent coagulant can enter the first filter cylinder 6 through the feed pipe 5 for filtration. After filtration, it is discharged from the filter cylinder 1 through the discharge pipe 3. When the filter cylinder 1 becomes clogged, the pump body 21 is turned off. Then, the first filter cylinder 6 and the second filter cylinder 7 can be interchanged by controlling the moving mechanism 8. Turning the pump body 21 back on quickly restores the filtration capacity of the filter cylinder, saving the time spent cleaning the filter cylinder 1 during production. When the filter cylinder 1 is idle or after a stage of coagulant filtration is completed, the impurities in the first filter cylinder 6 can be cleaned by opening the inspection port 11. Then, when the second filter cylinder 7 becomes clogged, it can replace the first filter cylinder 6 using the above method.
