Description

Technical Field

[0001] This utility model relates to the field of centrifuge equipment technology, specifically to a centrifuge mesh frame breaking and separating device. Background Technology

[0002] In the production processes of industries such as chemical, food, and pharmaceutical, it is often necessary to handle liquid materials (such as bagged solvents and emulsions) contained in sealed bags. In traditional processes, the separation of liquid materials from packaging bags is generally done manually. First, the bag must be manually broken open, and then the liquid materials must be separated by manual squeezing. This traditional process has the following drawbacks:

[0003] 1. Low work efficiency: The steps of breaking and separating the package are complicated and time-consuming.

[0004] 2. Incomplete separation of liquid and material: Manual breaking of packages can leave residual liquid, leading to waste of resources;

[0005] Third, poor operational safety: manual unpacking carries risks such as mechanical injury and chemical exposure. Utility Model Content

[0006] In view of this, the present invention provides a centrifuge mesh frame breaking and separating device, which can realize automatic breaking of material bags and efficient ejection of liquid material, improve the separation efficiency and operational safety of liquid material and packaging bag, and reduce the residue of liquid material in packaging bag.

[0007] A centrifuge mesh frame breaking and separating device includes a mesh frame body and spikes; the mesh frame body has uniformly distributed mesh holes on its circumferential surface, and the spikes are fixedly or detachably installed on the inner wall of the mesh frame body. The spikes are uniformly distributed along the circumferential and axial directions of the inner wall of the mesh frame body, and the spikes of the spikes point horizontally toward the central axis of the mesh frame body.

[0008] Furthermore, the circumferential and axial spacing of the spikes is 10–30 mm.

[0009] Furthermore, the frame body is equipped with symmetrical metal handles on both sides.

[0010] Furthermore, the overall shape of the spike is conical or prismatic, and the length of the spike is 5 to 20 mm.

[0011] Furthermore, the spike has a cutting edge on its side, which extends from the tip of the spike to its root.

[0012] Furthermore, the spikes are welded and fixed to the mesh frame body by argon arc welding.

[0013] Furthermore, a threaded section is machined at the root of the spike, and the threaded section passes through the through hole of the mesh frame body and is fixed by a nut to achieve a detachable connection between the spike and the mesh frame body.

[0014] Beneficial effects:

[0015] 1. This utility model has a high degree of functional integration: When the packaging bag containing liquid is placed into the mesh frame body and the centrifuge is started, the mesh frame body rotates at high speed, and the spikes move synchronously with the mesh frame body, using centrifugal force and inertia to puncture the packaging bag; the liquid is thrown out through the mesh under the action of centrifugal force, and the packaging bag, due to its large volume and light weight, is blocked by the spikes and the mesh frame body and remains inside the mesh frame body; it can be seen that the two steps of breaking the bag and centrifugal separation are completed simultaneously, which can shorten the process and improve work efficiency.

[0016] 2. This utility model can achieve efficient separation of liquid and packaging bag: because the spikes puncture the bag more thoroughly under the action of centrifugal force, and the liquid is thrown out under the synchronous action of centrifugal force, the liquid residue rate is lower than that of manual bag breaking, thus achieving efficient separation of liquid and packaging bag.

[0017] 3. The packaging breaking function of this utility model is highly adaptable: For packaging bags of different sizes, materials and thicknesses, the spike parameters (height, density) can be adjusted to adapt to packaging bags of different sizes and thicknesses, thereby improving the adaptability of the packaging breaking and separation function; In addition, the sides of the spikes have cutting edges, and the cutting edges are smoothly transitioned to the spikes and the root. The spikes are used to pierce the top of the bag, and the side wall spikes assist in breaking the bag, making the packaging breaking process smooth and with a high success rate.

[0018] 4. The structure of this utility model is reliable: the spikes are fixed to the frame body by welding (such as argon arc welding), and the spikes can withstand high-speed rotational impact and have a long service life.

[0019] 5. The modification cost of this utility model is low: the structure can be modified on the existing centrifuge mesh frame without replacing the whole machine, which makes the modification cost of the device low. Attached Figure Description

[0022] Among them, 1-mesh frame body, 2-spiky part, 3-mesh hole, 4-handle, 5-centrifuge interface. Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This utility model provides a centrifuge mesh frame breaking and separating device, including a mesh frame body 1, spikes 2 and handles 4.

[0025] Among them, as attached Figure 1 and 2 As shown, mesh holes 3 are evenly distributed on the circumferential surface of the frame body 1. Spikes 2 are fixedly or detachably mounted on the inner wall of the frame body 1. The spikes 2 are evenly distributed along the circumferential and axial directions of the inner wall of the frame body, with a circumferential and axial spacing of 10–30 mm and an overall length of 5–20 mm. The spikes point horizontally towards the central axis of the frame body 1. The size and thickness of the packaging bag can be adapted by changing the spike design parameters (height, distribution density, and arrangement) (e.g., increasing the spike density for larger packaging bags and using longer spikes for thicker packaging bags).

[0026] To facilitate the disassembly and installation of the device on the centrifuge, symmetrical metal handles 4 are installed on the outer side wall of the upper end of the wire mesh frame body 1.

[0027] In addition, in order to make the pack-breaking process smooth and successful, the side of the spike 2 has a cutting edge that extends from the tip of the spike to the root.

[0028] If the spike 2 is a fixed connection, the spike 1 is welded to the mesh frame body by argon arc welding. If the spike 2 is a detachable connection, a threaded section is machined at the root of the spike 1, and the threaded section passes through the through hole of the mesh frame body 1 and is fixed by a nut.

[0029] Working principle: First, the mesh frame body 1 of this utility model is installed in conjunction with the centrifuge. Then, the packaging bag containing liquid is placed into the mesh frame body 1 and the centrifuge is started. The mesh frame body 1 rotates at high speed, and the spikes 2 move synchronously with the mesh frame body 1. Under the inertial action of centrifugal force, the packaging bag is punctured by the front end of the spikes 1. Then, the liquid is thrown out through the mesh 3 under the action of centrifugal force. Because the packaging bag is large in volume and light in weight, it is blocked by the spikes 1 and the mesh frame body 1 and remains inside the mesh frame body 1.

[0030] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
