Technical Field
[0001] This utility model relates to the field of pressing device technology, and in particular to a pressing device for attapulgite adsorbent. Background Technology
[0002] Adsorbents, also known as absorbents, are substances that allow active ingredients to adhere to their particle surface, transforming liquid trace compound additives into solid compounds. This facilitates uniform mixing. They are solid substances that can effectively adsorb certain components from gases or liquids, possessing a large specific surface area, suitable pore structure, and surface structure. They have a strong adsorption capacity for adsorbates, generally do not chemically react with adsorbates or media, are easy to manufacture and regenerate, and have excellent adsorption and mechanical properties.
[0003] Attapulgite clay adsorbents are widely used in environmental protection, chemical industry, and other fields due to their high specific surface area and adsorption performance. Existing attapulgite adsorbents are usually in powder or loose granular form, which is prone to dust and moisture during transportation and storage, and has low filling efficiency in actual use. Existing compaction equipment has the following problems: the compacted blocks are easily loose and lack strength; the lack of coordinated control of temperature and pressure leads to uneven density.
[0004] Therefore, there is an urgent need to provide a compaction device for attapulgite adsorbent to solve the above problems. Utility Model Content

[0012] The present invention is further configured such that: the vibration unit includes a pushing member disposed on one side of the screen frame, a movable plate disposed on the other side of the screen frame, and a resetting member disposed on the side of the movable plate;
[0013] The number of reset components is multiple sets, and the multiple sets of reset components are equidistantly distributed on the side of the movable plate.
[0014] The present invention is further configured such that: the reset member includes a movable column disposed on the side wall of the opening and an elastic member disposed on the outside of the movable column, one end of the movable column is fixedly connected to the side of the movable plate, and a limit block is installed on the other end of the movable column.
[0015] The present invention is further configured such that: the forming unit includes a first pressing roller and a second pressing roller disposed opposite to each other inside the housing, and a driving part disposed on the side of the first pressing roller and the second pressing roller;

[0020] The present invention is further configured such that: a slot is provided at the bottom of the housing, and a collection box is provided inside the slot.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. This utility model uses a screening component to pour attapulgite adsorbent into the feed pipe. The attapulgite adsorbent falls into the screen frame along the feed pipe. Then, the pusher pushes the screen frame to slide along the opening of the fixed plate. When the screen frame collides with the movable plate, the elastic recovery of the elastic component and the cooperation of the movable column make the force generated by the impact transmitted to the screen frame. As a result, the attapulgite adsorbent inside the screen frame is vibrated by the force and falls down along the mesh of the screen frame, thereby improving the quality of the attapulgite adsorbent.
[0023] 2. In this invention, the clamping assembly allows the attapulgite adsorbent to fall onto the top of the connection between the first and second clamping rollers. A heating wire then heats and softens the adsorbent located inside the hemispherical groove. Simultaneously, a drive mechanism rotates the active gear. Since the active and driven gears mesh, the first and second clamping rollers rotate relative to each other. When the first and second clamping rollers rotate to correspond to the hemispherical grooves on their outer surfaces, pressure compresses the attapulgite adsorbent into a spherical structure. The cooling water inside the cooling channel further cools the spherical structure, making it more stable and less prone to loosening. Attached Figure Description

[0038] There are multiple sets of reset components 233, which are equidistantly distributed on the side of the movable plate 232.
[0039] The reset component 233 includes a movable column 2331 disposed on the side wall of the opening 211 and an elastic element 2332 disposed on the outside of the movable column 2331. One end of the movable column 2331 is fixedly connected to the side of the movable plate 232, and a limit block 2333 is installed on the other end of the movable column 2331. Preferably, the elastic element 2332 is a reset spring.
[0040] The forming unit 32 includes a first pressing roller 321 and a second pressing roller 322 disposed opposite to each other inside the housing 31, and a driving portion 323 disposed on the side of the first pressing roller 321 and the second pressing roller 322.
[0041] Both the outer surfaces of the first pressing roller 321 and the second pressing roller 322 are provided with hemispherical grooves 3211. Preferably, both the outer surfaces of the first pressing roller 321 and the second pressing roller 322 are provided with a plurality of hemispherical grooves 3211 at equal intervals.

As a result, the attapulgite adsorbent inside the screen frame 22 is vibrated by the force and falls down along the mesh of the screen frame 22.
[0047] When the attapulgite adsorbent falls to the top of the connection between the first pressing roller 321 and the second pressing roller 322, the attapulgite adsorbent located inside the hemispherical groove 3211 is heated and softened by the heating wire 3212. The driving component 3231 drives the drive gear 3232 to rotate. Since the drive gear 3232 meshes with the driven gear 3233, the first pressing roller 321 and the second pressing roller 322 rotate relative to each other. When the first pressing roller 321 and the second pressing roller 322 rotate to the position corresponding to the hemispherical groove 3211 on their outer surfaces, the attapulgite adsorbent is compressed into a spherical structure under pressure. Then, the attapulgite adsorbent compressed into a spherical structure is cooled by the cooling water inside the cooling channel 3221, making its structure more stable and less prone to loosening.
