Description

Technical Field

[0001] This utility model belongs to the field of supporting facilities for activation feeders, and in particular relates to a new type of feed hopper for activation feeders. Background Technology

[0002] An activated feeder is a device used for conveying bulk materials and is widely used in industrial sites such as thermal power plants and logistics parks. The activated feeder is positioned below the concrete or steel hoppers storing bulk materials, straddling the lower conveyor belt that receives the materials. Its compact design reduces installation space, thereby lowering the height of plant corridors and reducing overall costs.

[0003] The activated feeder is a vibratory device, and the main body of the device must be separated from the fixed foundation. Therefore, the conventional installation method requires first installing the feed hopper under the fixed concrete hopper or steel hopper, then hoisting the activated feeder body so that the inner wall and the circumference of the feed hopper are kept 30-40mm apart, and then vertically lifting the main body so that the feed hopper is inserted into the main body of the device 70-80mm. The construction involves multiple sequential steps and is not a straightforward one-piece installation sequence.

[0004] If the installation process ignores the above installation sequence and instead simply installs the equipment as a single unit from top to bottom without properly maintaining the internal dimensions, the bulk materials inside the equipment will squeeze into the flexible connection after installation, eventually completely filling the flexible connection and causing the equipment to malfunction and fail to vibrate properly. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this utility model provides a novel activated feeder hopper with a novel design. It can achieve the original installation effect by welding the whole hopper to the pre-embedded iron under the concrete hopper or steel hopper, and the installation is convenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel activated feeder hopper, comprising an inner feed hopper, an outer feed hopper, a top flange, a bottom flange, a limiting bolt, a fixing bolt, and a flexible connection sealing cover. Both the inner and outer feed hoppers are hollow tubular structures with a square cross-section. The top of the inner feed hopper is connected to a top flange, and the bottom of the inner feed hopper is connected to a bottom flange. The outer feed hopper is sleeved outside the inner feed hopper, and the tops of the inner and outer feed hoppers are connected by a flexible connection sealing cover. Each side of the inner feed hopper is provided with several welded nuts, and the outer feed hopper is provided with through holes at the corresponding positions of the welded nuts. The limiting bolt passes through the through holes and is connected to the welded nuts. The aforementioned bottom flange is provided with several fixing bolts and bolt mounting holes.

[0007] In the above technical solution, the number of welded nuts on each side of the inner feed hopper is at least 4.

[0008] In the above technical solution, several of the welding nuts are arranged in a rectangular shape.

[0009] In the above technical solution, the rod length of the limiting bolt is 40mm, and the opening size of the outer feed hopper is 40mm larger than the opening size of the inner feed hopper.

[0010] The beneficial effects of this utility model are: its design is novel. After the structure is fixed to the equipment body by bolts on the flange hole, its top is welded to the embedded part under the concrete hopper or steel hopper, and the limiting bolt can be removed; construction and installation do not require setting and adjusting the installation gap between the feed hopper and the body on site, nor do they require performing the construction of the body sleeve feed hopper and adjusting the insertion distance; using the feed hopper of this structure can completely avoid the situation where material is squeezed into the flexible connection due to construction quality, causing the equipment to malfunction.

[0014] Figure 4 This invention is installed between the activated feeder and the concrete hopper.

[0015] The components include: 1. Top flange, 2. Inner feed hopper, 3. Outer feed hopper, 4. Limit bolt, 5. Bottom flange, 6. Fixing bolt, 7. Flexible connection sealing cover, and 8. Welded nut. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 4The novel activation feeder hopper shown includes an inner feed hopper 2, an outer feed hopper 3, a top flange 1, a bottom flange 5, limiting bolts 4, fixing bolts 6, and a flexible connection sealing cover 7. Both the inner feed hopper 2 and the outer feed hopper 3 are hollow tubular structures with a square cross-section. The top of the inner feed hopper 2 is connected to the top flange 1, and the bottom of the inner feed hopper 2 is connected to the bottom flange 5. The outer feed hopper 3 is fitted over the inner feed hopper 2, and the tops of the inner feed hopper 2 and the outer feed hopper 3 are connected by the flexible connection sealing cover 7. Each side of the inner feed hopper 2 is provided with several welding nuts 8, and the outer feed hopper 3 is provided with through holes at the corresponding positions of the welding nuts 8. The limiting bolts 4 pass through the through holes and are connected to the welding nuts 8. The bottom flange 5 is provided with several fixing bolts 6 and bolt mounting holes, so that the feed hopper can be fixed to the upper opening of the activation feeder body.

[0018] In the above technical solution, the number of welded nuts 8 on each side of the inner feed hopper 2 is at least 4. The large number of welded nuts 8 and limiting screws 4 can stably separate the inner feed hopper and the outer feed hopper.

[0019] In the above technical solution, the welded nuts 8 are arranged in a rectangular shape. The rectangular arrangement of the welded nuts 8 makes the force separating the inner feed hopper and the outer feed hopper more uniform, and facilitates installation and removal.

[0020] In the above technical solution, the rod length of the limiting bolt is 40mm, and the opening size of the outer feed hopper is 40mm larger than the opening size of the inner feed hopper.

[0021] When installing the feed hopper on site, first install it onto the activated feeder body using the fixing bolts 6 of the bottom flange 5. Then, weld the top of the entire feed hopper onto the embedded part under the concrete hopper or steel hopper. Remove the limiting bolts 4 on the outer feed hopper 3 to complete the installation. A removal sign can be hung on the limiting bolts 4 to prevent construction personnel from missing it.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
