Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral processing equipment, in particular to a floating balance type electronic belt scale for a belt filter. Background Art
[0002] As a new type of solid-liquid separation filtration equipment with a high degree of automation, the vacuum belt filter has high filtration efficiency and is therefore preferred by many industries. The solids separated by this equipment are usually transported and weighed by a belt conveyor installed with an electronic belt scale, which increases the investment cost and insufficient weighing accuracy.
[0003] Traditional electronic weighing scales can only meet the needs of equipment with a width of less than 2 meters in a dynamic state and require a large installation space. Furthermore, the weighing structure used in existing vacuum belt filters is relatively fixed. Applying electronic belt scales to filters without weighing structures requires major modifications to the original filter, resulting in changes in the original filter's performance, incurring labor costs and structural changes. Therefore, it is difficult to find a suitable solution. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a floating balanced electronic belt scale for a belt filter, which has a strong anti-eccentric load capability and solves the shortcomings of existing electronic weighing and metering scales that cannot adapt to wide vacuum belt filters and require a large installation space. The scale can be suitable for the installation of filter equipment of various models, widths and speeds.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A floating balanced electronic belt scale for a belt filter has an equipment body of a filter, a circulating filter cloth is arranged on the equipment body, the filter cloth is supported by multiple first rollers on the equipment body, the filter cloth and the belt form a driving cooperation, the belt is wound on two driving wheels, and a weighing bridge module consisting of a second roller, a floating balancing frame and a weighing sensor is arranged on the discharge end of the equipment body. The number of second rollers is more than two, and the second rollers are installed on the bottom of the floating balancing frame. The floating balancing frame is arranged on the left and right sides of the filter cloth. The bottom of the floating balancing frame is correspondingly provided with a weighing sensor, and the weighing sensor is installed on the end of the equipment body.
[0007] As a further improvement of the above technical solution:
[0008] The second rollers are horizontally arranged on the bottom surface of the filter cloth, and each second roller extends to both sides of the filter cloth. The two ends of each second roller are rotatably connected to the corresponding mounting seat, and the mounting seat is upwardly mounted on the bottom surface of the floating balance frame.
[0009] The mounting seat adopts a bearing seat with a bearing assembly.
[0010] The floating balancing frame is arranged on both sides of the filter cloth along the length direction of the filter cloth.
[0011] The load cell is connected to the bottom of the floating gimbal through a universal joint.
[0012] The weighing sensor is fixedly installed on the main body of the equipment at a position on one side of the filter cloth.
[0013] A weighing sensor is correspondingly arranged at each of the two ends of the bottom of the floating balancing frame.
[0014] The load-bearing parts of the two weighing sensors are cylindrical and connected to the floating balance frame through a universal joint.
[0015] It also includes an integrator. A speed sensor is set on the main body of the equipment. The speed sensor measures the rotation speed of the driving wheel. The integrator is connected with the weighing sensor and the speed sensor for electrical signal connection. The integrator measures the weight of the material transmitted on the filter.
[0016] The filter cloth has a horizontal section with a horizontal surface. The lower surface of the filter cloth in the horizontal section forms a driving fit with the adhesive belt, so that the entire filter cloth is circulated and driven.
[0017] The beneficial effects of the utility model are as follows:
[0018] This new system utilizes the existing main structure of the vacuum belt filter for installation, offering strong resistance to off-center loading. This overcomes the drawback of existing electronic weighing and metering scales, which are incompatible with wide vacuum belt filters. This new system can accommodate wide vacuum belt filters (over 3 meters). It also addresses the issue of existing electronic weighing and metering scales requiring large installation space, making it impossible to install the weighing system if the filter installation space is too small. Because this new system utilizes the existing roller structure, existing roller positioning, and existing space, it eliminates the need to modify the main structure of the vacuum belt filter for installation, making it suitable for installation on a variety of different models, widths, and speeds.

[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0024] Reference Figures 1 to 3 As shown, the floating balanced electronic belt scale for a belt filter described in the present invention comprises a filter body 1, on which is disposed a circulating filter cloth 2, which is a closed, wound belt-like structure. The filter cloth 2 is supported on the body 1 by a plurality of first rollers 3. The filter cloth 2 has a horizontal section with a horizontal surface. The lower surface of the filter cloth 2 in this horizontal section forms a driving engagement with the adhesive tape 4, causing the entire filter cloth 2 to circulate. The adhesive tape 4 is wound around two drive wheels 5, which drive the adhesive tape 4, which in turn drives the filter cloth 2 in a circulating manner. The slurry to be processed flows from an external discharge device onto the horizontal section of the filter cloth 2, where it is then carried forward by the filter cloth 2. During this process, the slurry on the filter cloth 2 is dehydrated and dried by a vacuum device.
[0025] The present invention provides a weighing bridge module comprising second rollers 6, a floating balancing frame 7, and a load cell 8 at the discharge end of the main body 1 of the device. The number of second rollers 6 is two or more, and the second rollers 6 are mounted on the bottom of the floating balancing frame 7. The floating balancing frame 7 is arranged on the left and right sides of the filter cloth 2. The bottom of the floating balancing frame 7 is correspondingly provided with load cells 8, and the load cells 8 are mounted on both sides of the end of the main body 1. The present invention utilizes existing second rollers 6 for installation. At least two second rollers 6 are horizontally arranged on the bottom surface of the filter cloth 2, and each second roller 6 extends to both sides of the filter cloth 2. The two ends of each second roller 6 are rotatably connected to corresponding mounting seats 9. The mounting seats 9 are preferably bearing seats with bearing assemblies. The mounting seats 9 are upwardly mounted on the bottom surface of the floating balancing frame 7. The floating balancing frame 7 is arranged on both sides of the filter cloth 2 along the length direction of the filter cloth 2. The bottom of the floating balancing frame 7 is correspondingly provided with load cells 8, and the load cells 8 are connected to the bottom of the floating balancing frame 7 via universal joints. Preferably, a weighing sensor 8 is provided at each of the two ends of the bottom of the floating balancing frame 7 . The weighing sensor 8 is fixedly mounted on the discharge end of the equipment body 1 and is located on one side of the filter cloth 2 .
[0026] The present invention includes a speed sensor 10 on the main body 1 of the device, which measures the rotational speed of the drive wheel 5. The present invention also includes an integrator, which is electrically connected to the load cell 8 and the speed sensor 10. The weight value measured by the load cell 8 and the rotational speed of the drive wheel 5 measured by the speed sensor 10 are both transmitted to the integrator, which then calculates and measures the weight of the material being transported through the filter.
[0027] The utility model adds a set of floating balanced weighing bridge modules to the equipment body 1 of the vacuum belt filter. The weighing bridge modules are installed using the roller structure of the equipment itself. Floating balancing frames 7 are installed at both ends of the second roller 6 at the discharge end of the original equipment. Two weighing sensors 8 are respectively installed at the bottom of the floating balancing frames 7. The floating balancing frames 7 are connected to the weighing sensors 8 to form an integral weighing bridge.
[0028] Because the load-bearing structures of the two load cells 8 are cylindrical, they are each connected to the floating gimbal 7 via a universal joint. The floating gimbal 7 transmits the weight of the material on the filter cloth 2 to the load cells 8. Since the second roller 6 is connected to the load cells 8 solely via the floating gimbal 7, it floats freely, eliminating any interference or internal structural stress. The floating gimbal 7 accurately transmits the full weight of the material on the filter cloth 2 to the load cells 8, achieving highly accurate measurement. Because the four load cells 8 are mounted at both ends of the floating gimbal 7, they offer strong resistance to off-center loads and adapt to the wide range of vacuum belt filters.
[0029] This utility model utilizes the operating principle of an electronic belt scale, with a load cell 8 and a speed sensor 10 working in synergy. As material passes through the weighing bridge module, the metering second roller 6 detects the weight of the material on the filter cloth 2 and accurately transmits this weight to the load cell 8, achieving high-precision measurement. Furthermore, the speed sensor 10 is directly connected to the drive wheel 5 of the device body 1, effectively preventing variations in the hardness and tension of the filter cloth 2 from affecting speed accuracy.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
