Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter press technology, specifically to a filter press vibration unloading mechanism. Background Technology
[0002] After the filter press completes the extrusion and drying process, the fine residue produced by the filter press and the solids produced by the three-phase process are collected and temporarily stored in the fine residue box for resource utilization.

However, the solids conveying screw pump cannot meet the conveying requirements, often gets clogged, and there is no standard data for adjusting the pump speed, making it quite cumbersome to use. Therefore, a vibrating discharge mechanism for the filter press is designed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a filter press vibration unloading mechanism, comprising: a hollow fine slag box 1 with an open top; a shell 2 with an arc-shaped lower end is bolted to the lower outlet of the fine slag box 1; a motor 3 is fixedly connected to the left side of the shell 2; a conduit 4 is provided on the right side of the shell 2; a spiral push rod 5 is fixedly connected to the output end of the motor 3 on the right side; the spiral push rod 5 is close to the inner wall of the shell 2; a controller 6 is provided at the front end of the fine slag box 1; a humidity sensor 7 is bolted to the front surface of the connection between the fine slag box 1 and the shell 2; the detection end of the humidity sensor 7 extends through the fine slag box 1 into the interior; the connection between the fine slag box 1 and the shell 2 is at a 15-degree angle; and the controller 6 is electrically connected to the humidity sensor 7 and the motor 3.
[0024] During use, the material unloaded from the filter press falls into the fine residue box 1. The humidity sensor 7 detects the humidity of the material in the fine residue box 1, and the humidity data is transmitted to the controller 6. The controller 6 adjusts the speed of the motor 3 according to the humidity of the material. When the motor 3 rotates, it drives the screw push rod 5 to rotate. Since the outer side of the screw push rod 5 is spiral and the inner wall of the guide tube 4 and the outer wall of the outer shell 2 are close to the outer side of the screw push rod 5, when the screw push rod 5 rotates, it pushes the material outward. The material falls through the end of the guide tube 4 to proceed to the next process.
[0025] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the left side of the conduit 4 is connected to the right side of the outer shell 2 through a flange. A fixing ring 21 is sleeved on the right side of the outer surface of the conduit 4. The upper and lower ends of the fixing ring 21 are connected by bolts. The upper end of the upper fixing ring 21 is connected to the lower right end of the fine slag box 1 through a fixing rod 22. A rubber pad is fixedly connected to the inner side of the fixing ring 21.
[0026] Analysis of the above structure shows that when it is necessary to inspect, maintain or clean the residue inside the guide tube 4 of the outer blade of the spiral push rod 5, the bolts on the outer side of the flange are removed, and then the bolts on the front and rear sides of the fixing ring 21 are loosened to remove the guide tube 4 for easy cleaning, while also reinforcing the guide tube 4.
[0027] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a vibration motor 23 is bolted to the upper side of the end of the conduit 4, and the vibration motor 23 is electrically connected to the controller 6.
[0028] Analysis of the above structure shows that when in use, the vibration motor 23 is started, which causes the conduit 4 to vibrate, causing some dried residues that are stuck to the inner wall of the conduit 4 to fall off, reducing blockage.
[0029] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, the right side of the front surface of the fine slag box 1 is connected to an audible and visual alarm 24 by bolts, and the audible and visual alarm 24 is electrically connected to the controller 6.
[0030] Analysis of the above structure shows that when a blockage occurs inside the conduit 4, the audible and visual alarm 24 will be activated and the rotation of the motor 3 will be turned off to remind the staff to check and maintain it.
[0031] like Figure 1-4 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a torque sensor 25 is sleeved on the outer side of the output end of the motor 3, and the torque sensor 25 is electrically connected to the controller 6.
[0032] Analysis of the above structure shows that the torque sensor 25 detects the torque of the motor 3. When the torque is too high, the motor 3 will stop rotating and the audible and visual alarm 24 will be activated to remind the staff to clean the inside of the conduit 4.
[0033] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the lower end of the fine slag box 1 is sloping and the inner wall is made of stainless steel.
[0034] Analysis of the above structure shows that the lower end of the fine slag box 1 is sloping, which can guide the material, while the inner wall is made of stainless steel, which can reduce surface friction and corrosion, thereby extending the service life.
[0035] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the outer surfaces of the conduit 4 and the spiral push rod 5 are both coated with Teflon.
[0036] Analysis of the above structure shows that the outer surfaces of both the conduit 4 and the spiral push rod 5 are coated with Teflon, which can reduce the probability of material adhering to the inside of the conduit 4 and the outer surface of the spiral push rod 5.
