Description

Technical Field

[0001] This utility model relates to the field of powder filtration technology, and in particular to a filtration device for bulk powder materials entering a warehouse. Background Technology

[0002] Powder materials are essential raw materials for the production of various materials. Waste gypsum, waste concrete particles, slag, and steel slag are important raw materials for preparing cement, concrete, and other building materials. Waste gypsum can improve and regulate the setting time of cement and concrete, increasing early strength. Waste concrete particles can be used as coarse aggregate in concrete, realizing the resource utilization of waste. Slag and steel slag can be used as auxiliary cementitious materials to reduce the amount of cement clinker used in concrete, and can also be used as raw materials for firing cement clinker. However, these powder materials are often easily mixed with impurities during the generation, collection, and packaging stages, such as plastic bags, cloth strips, stones, and even iron parts. This not only easily causes mechanical damage to these powder materials in subsequent processing but also adversely affects the quality of the produced products. Therefore, filtering the powder materials upon entry into the warehouse to remove impurities is an important measure to reduce the above problems. Utility Model Content

[0020] refer to Figure 1 , Figure 2 and Figure 3 Example: A bulk powder material warehousing and filtration device includes: a feed hopper 1, a discharge pipe 2, a connecting plate 3, a filter screen 4, and a support member 5. Specifically: The upper end of the feed hopper 1 is a conical opening to facilitate the entry of powder. The lower end of the feed hopper 1 is a square cylinder with an upward-sloping lower end. The inclination angle can be arbitrarily selected between 20° and 45°, such as 20°, 30°, 40°, 45°, etc. The discharge pipe 2 is a square cylinder that matches the lower end of the feed hopper 1, and the upper end of the discharge pipe 2 is also an upward-sloping opening. Its inclination angle is the same as that of the lower end of the feed hopper 1, allowing the two to be matched and connected.

[0021] The upper inclined opening of the feed pipe 2 has an integrated connecting plate 3 on its left, front, and rear side walls. The lower inclined opening of the feed hopper 1 also has an integrated connecting plate 3 on its left, front, and rear side walls, and the connecting plates 3 on the front and rear side walls have connecting holes 301. After the lower inclined opening of the feed hopper 1 is aligned with the upper inclined opening of the feed pipe 2, the bolt fastener 302 passes through the connecting hole 301 and is connected to the nut, thereby detachably fastening the lower and upper inclined openings together. The lower inclined opening of the feed hopper 1 and the right side wall of the upper inclined opening of the feed pipe 2 are connected by a hinge, pin, or other rotating connecting parts 6, so that the feed hopper 1 can be rotated clockwise relative to the feed pipe 2 to open and form a discharge port, or rotated counterclockwise to re-align and close the two together. The connecting plate 3 on the left side wall of the upper inclined opening of the feed pipe 2 can also assist the debris to slide down, making it easier for the debris to fall into the collection box / bag below.

[0022] The filter screen 4 is inclinedly disposed in the upper inclined opening of the feed pipe 2, and several support members 5 are fixed on the inner wall of the upper inclined opening, distributed circumferentially. The filter screen 4 is supported on the support members 5, and the two are detachably connected to facilitate replacement of the filter screen 4. The inclination angle of the filter screen 4 is the same as that of the upper inclined opening of the feed pipe 2, and the filter screen 4 is flush with the inclined opening to facilitate cleaning of the impurities filtered and trapped by the filter screen 4. The filtration device of this embodiment can not only filter and trap impurities in powder through the filter screen, but also can be easily opened by flipping the feed hopper, so as to easily clean the filtered impurities without disassembling the whole device. After cleaning, the feed hopper is flipped again to connect with the feed hopper, and then detachably connected by the fastener 302, so that it can be reused for filtering powder materials entering the warehouse.

[0023] In another embodiment, a flexible sealing ring is provided between the lower port of the feed hopper 1 and the upper port of the discharge pipe 2 of the bulk powder material warehousing and filtering device of the above embodiment. The ring is fixed to the lower surface of the connecting plate 3 of the feed hopper 1, or it can also be fixed to the upper surface of the connecting plate 3 of the discharge pipe 2, to increase the sealing performance between the two. The flexible sealing ring can be made of rubber, plastic, etc. Furthermore, the flexible sealing ring can also act as a buffer when the discharge port is closed.

[0024] In another embodiment, a handle is fixed on the right side wall of the upper port of the bulk powder material warehousing and filtering device of the above embodiment, so as to pull the feed hopper 1 to flip it over and open it to form a discharge port, which is convenient for cleaning the debris that is filtered and trapped by the filter screen plate 4. Some debris can also slide down automatically along the filter screen plate 4 to achieve automatic cleaning.

[0025] In another implementation, refer to Figure 4 The filter plate 4 of the bulk powder material warehousing filtration device in the above embodiment includes a filter screen 401 and a guide plate 402. Specifically, there are two guide plates 402, vertically arranged, with their lower ends fixedly connected to the front and rear sidewalls of the filter screen 401, respectively, and perpendicular to each other, thus forming a groove-shaped structure. After the filter plate 4 is installed in the upper inclined opening of the feed pipe 2, the filter plate 4 maintains the same inclination as the inclined opening. The guide plates 402 are located on the inner sides of the front and rear sidewalls of the upper inclined opening, and the sidewalls of the guide plates 402 are attached to the sidewalls of the upper inclined opening. The upper surface of the filter screen 401 is flush with the upper inclined opening. After the feed hopper 1 is connected to the feed pipe 2, the upper end of the guide plate 402 extends into the lower port of the feed hopper 1, and their sidewalls are attached together. In this embodiment, the filter plate 4 can not only filter and retain impurities in powder materials, but also guide the impurities that automatically slide down after the tilting feed hopper 1 is opened, so that they are discharged from the lower end of the filter plate 401. At the same time, the guide plate 402 also helps to strengthen the stability of the connection between the feed hopper 1 and the discharge pipe 2, and facilitates the removal of the filter plate 4.

[0026] In another implementation, refer to Figure 4 The lower end face of the guide plate 402 of the bulk powder material warehousing and filtering device in the above embodiment has a positioning post 403. (See reference) Figure 3 The support member 5 has a positioning hole 501 corresponding to the positioning post 403. When the filter screen plate 4 is supported on the support member 5, the positioning post 403 is inserted into the positioning hole 501, thereby detachably connecting the filter screen plate 4 and the support member 5. In a preferred embodiment, a spring is fitted on the positioning post 403, the lower end of which is supported on the support member 5, and the upper end of which is connected to the lower end face of the guide plate 402. The spring is compressed under the action of the filter screen plate 4, so that during filtration, the impact of the powder material can drive the filter screen plate 4 to perform small-amplitude reciprocating lifting and lowering, promoting the passage of powder material trapped on the filter screen plate 4.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
