[0002] The Pilates bed is a health training device. Its iron accessories often need to be surface treated during use. Grinding is an important step to ensure the performance of the accessories. A large amount of metal dust will be generated during the grinding process of iron accessories. If it is not handled properly, it will easily cause environmental pollution and waste of resources. The iron accessory grinding equipment commonly used in the prior art mainly adopts the following dust treatment methods: one is to set a simple dust collection device in the grinding area to directly collect dust through negative pressure suction; the other is to use a single filter or magnetic adsorption device for dust treatment.

[0003] These traditional dust treatment methods have the following problems: First, a single dust collection device is difficult to cope with dust of different properties and particle sizes generated during the grinding process, resulting in low collection efficiency; second, simple filter screens are prone to clogging and need to be replaced frequently, increasing maintenance costs; third, traditional magnetic adsorption devices often adopt a fixed layout, which cannot fully contact the dust and easily form dust agglomerations, affecting the adsorption effect; fourth, the dust collection area has poor sealing, which can easily cause secondary pollution; fifth, there is a lack of a grading treatment mechanism for the collected dust, which is not conducive to subsequent recycling.

[0004] Therefore, a separation and collection method is needed that can efficiently process the grinding dust of iron accessories and has good environmental protection and economy. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined Figure 1-Figure 10 The preferred embodiments of the present invention are described in detail. It should be noted that the following description is only a preferred embodiment of the present invention, rather than a limitation of the present invention. Those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.

[0021] Example 1 See first Figure 1-Figure 4 The method of the present invention provides a method for separating and collecting iron dust from a special grinding device for iron accessories of a Pilates bed. The method utilizes a combination of penetration diversion, variable cross-section adsorption and multi-stage filtration to achieve efficient separation and collection of metal dust. By extending the dust movement path and setting multiple collection points, dusts of different particle sizes and properties are introduced into corresponding processing channels to form a graded collection circulation system. The specific steps are as follows: 1. Constructing a separate collection space A grinding area 02 and a dust collection area 03 are constructed inside the frame 10 of the special grinding equipment for the iron accessories of the Pilates bed. The grinding area 02 is provided with a workbench 20 and a grinding fixture 30 that can be moved along the XY horizontal plane, and a horizontally arranged cylindrical grinding wheel 40 is provided above the grinding fixture 30. The dust collection area 03 is completely isolated from the external environment by a sealing structure.

[0022] 2. Establish a three-level separation and processing area The first treatment area 04, the second treatment area 05 and the third treatment area 06 are arranged in sequence along the dust treatment direction. The first treatment area 04 adopts gravity sedimentation combined with directional flow guidance; the second treatment area 05 adopts magnetic adsorption combined with variable cross-section adsorption; the third treatment area 06 adopts a filter vibration device.

[0023] 3. Installation and configuration of multi-stage separation components First, a dust multi-stage separation device 50 is installed in the dust collection area 03, and the device includes a first isolation component 51, a second isolation component 52, a dust suction pipe 53 and a dust scraping structure 54. The first isolation component 51 is arranged between the first processing area 04 and the second processing area 05, the second isolation component 52 is arranged between the second processing area 05 and the third processing area 06, the dust suction pipe 53 covers the first processing area 04 and the second processing area 05, and the dust scraping structure 54 is arranged at the far end of the third processing area 06.

[0024] The penetration plate 511 of the first isolation component 51 is formed by arranging fine lines of high-strength nylon material at equal intervals. The arrangement direction of the fine lines is adapted to the movement trajectory of the dust.

[0025] In addition, in some embodiments, the penetration plate 511 adopts a double-layer honeycomb composite structure, which is arched as a whole and has an inclination angle of 15-20° with the horizontal plane. The outer mesh uses a large-sized honeycomb unit with a side length of 15-18mm, and 5-6 layers of shallow corrugations (peak height 1.5-2mm) are formed on the inner circumference, and the mesh diameter is 1.2-1.5mm, which are evenly distributed along the radial direction to form an initial receiving cavity; the inner mesh uses a small-sized honeycomb unit with a side length of 6-8mm, and 2-3 layers of deep corrugations (peak height 3-4mm) are arranged on the inner circumference, and the mesh diameter is 0.8-1.0mm. The central axis of the outer unit points to the focus of the arch, and is staggered with the inner layer and coincides with the upper boundary. A variable cross-section cavity is formed between the two layers of mesh, and the inner spacing is 3mm and gradually transitions to 5mm outward. When dust enters, it is first received and buffered by the upper space of the outer large-sized honeycomb unit, and then multi-level buffering is performed through the corrugated structure of the inner and outer layers. The variable cross-section cavity gradually expands from the inside to the outside, causing the dust to form a spiral motion trajectory. The independent vibration and resonance effect of the two layers of mesh cloth produce a stable eddy current field, significantly extending the retention time of the dust in the system. In addition, based on the flexible characteristics of the mesh cloth material, the outer surface of the arched structure produces high-frequency and violent structural oscillations under the continuous impact of dust. This oscillation forms a strong dynamic collision with the naturally falling dust in the second processing area 05, which not only significantly changes the motion trajectory of the dust, but also makes the dust form a discrete state in space, greatly increasing the contact opportunity between the dust and the magnetic adsorption cylinder 521, thereby improving the dust capture efficiency.

[0026] The first guide plate 512, the second guide plate 513 and the penetration plate 511 form a complete flow diversion system, which extend to the junction of the grinding area 02 and the air inlet area of ​​the dust collection pipe 53 respectively. The second isolation component 52 is composed of a magnetic adsorption cylinder 521 made of permanent magnetic material, a drive motor 522, a third guide plate 523 and an arc guide plate 524, wherein the arc guide plate 524 is coaxially designed with the magnetic adsorption cylinder 521 and a gap is reserved, which not only provides a directional flow channel for dust but also ensures the degree of rotation freedom. The dust collection pipe 53 is provided with a plurality of layers of filter cotton arranged obliquely, which are a coarse filter layer, a medium and fine filter layer and an ultrafine filter layer, respectively, which are responsible for intercepting fine particles such as abrasive particles, resin particles and PM2.5. The dust scraping structure 54 includes a fixed scraping plate 541 connected by a hinge shaft and a receiving groove 542 for collection. A filter screen 56 with a special mesh structure is provided in the third processing area 06 to collect residual metal dust.

[0027] 4. Specific steps of separation, collection and treatment method Step 1: Initial processing stage After starting the equipment, the cylindrical grinding wheel 40 rotates at high speed to grind the iron accessory 01, and the generated metal dust enters the first isolation component 51. Since the first isolation component 51 adopts a double-layer honeycomb composite structure, the dust is first received by the upper space of the outer large-sized honeycomb unit (side length 15-18mm), and is initially buffered by the shallow corrugated structure. Subsequently, the dust forms a spiral motion trajectory in the 3-5mm variable-section cavity between the inner and outer layers of mesh, and is further decelerated by the deep corrugations of the inner small-sized honeycomb unit (side length 6-8mm). This combination of multi-level buffering and directional diversion allows mixed dust of different densities to be gradually stratified during movement, laying the foundation for subsequent graded collection.

[0028] Step 2: Grading and collection stage The dust that has been diverted and spirally guided by the double-layer honeycomb structure of the first isolation component 51 enters the second processing area 05, where a large part of the iron dust is preferentially captured by the magnetic adsorption tube 521 due to its magnetic characteristics. The variable cross-section structure between the first processing area 04 and the second processing area 05 generates a pressure gradient, which forms a classification effect on the remaining dust: a part of the abrasive particles and resin particles are intercepted and graded by the multi-layer filter cotton in the dust collection pipe 53; the other part of the dust that is not magnetically adsorbed and filtered is directed along the preset gap channel between the arc-shaped guide plate 524 and the magnetic adsorption tube 521 under the action of the airflow into the third processing area 06 for subsequent treatment.

[0029] Step 3: Cleanup and Recycling When grinding is paused and switched, the magnetic adsorption cylinder 521 moves to the dust scraping structure 54 for cleaning. During this movement, the magnetic adsorption cylinder 521 produces a secondary adsorption effect on the iron dust on the surface of the filter screen 56 when passing above the filter screen 56, further improving the recovery rate of the iron dust. When the magnetic adsorption cylinder 521 reaches the specified position, the dust is effectively collected through the reciprocating spring of the fixed scraping plate 541 and the continuous vibration of the filter screen 56. The mechanical interference between the magnetic adsorption cylinder 521 and the fixed scraping plate 541 continuously promotes the vibration of the filter screen 56, so that the dust can be fully removed and recovered. This combination of secondary adsorption during the movement process and the final mechanical removal significantly improves the system's recovery efficiency of iron dust.

[0030] Example 2 On the basis of Example 1, this method adds a directional airflow system to the double-layer honeycomb structure of the first isolation component 51: Several airflow nozzles are set on both sides of the arch structure, divided into two circles. The inner circle nozzles are aimed at the deep corrugations of the inner mesh, and the outer circle nozzles are aimed at the shallow corrugations of the outer mesh. The angle between the nozzles and the corrugated surface is 10-15°. The airflow pulse frequency is synchronized with the dust generation rate to form a reverse disturbance force.

[0031] Working process: When the dust enters the double-layer honeycomb structure, the outer airflow first destroys the dust agglomeration, and the inner airflow further disperses the dust. Under the disturbance of the airflow, the spiral motion is more complete, which enhances the natural separation effect of the dust according to the material characteristics. The separated iron dust is easier to be captured by the subsequent magnetic adsorption cylinder 521.

[0032] This improvement makes full use of the spatial characteristics of the double-layer honeycomb structure and improves the separation efficiency.

[0033] Example 3: Coordinated optimization scheme of multi-pole magnetic field and arc-shaped flow guide system This embodiment forms a synergistic separation system by optimizing the magnetic field structure of the magnetic adsorption cylinder 521 and matching the improved arc guide plate 524. Eight permanent magnet arrays are evenly arranged along the circumference of the outer periphery of the magnetic adsorption cylinder 521. Each array adopts an NSN three-pole structure (pole length 30mm, width 15mm). The driving motor 522 drives the whole to rotate at a speed of 15-20r / min to generate a dynamic alternating magnetic field. The arc guide plate 524 is located directly below the adsorption cylinder. The arc part is coaxially arranged with the adsorption cylinder, with a top gap of 10mm; the whole is a 90° arc with a radius of 200mm, and the starting end is at an angle of 15° with the horizontal plane. The inner layer is made of 6061 aluminum alloy with a wall thickness of 2.5mm. It is equipped with two 45° spiral grooves (groove depth 1.8mm, width 3.5mm) to guide the dust movement clockwise downward; the outer layer is made of Q235 low-carbon steel with a wall thickness of 3.5mm. Eight elliptical grooves (length 15mm, width 8mm, depth 2.5mm) are set corresponding to the position of the permanent magnet to strengthen the local magnetic field. The double-layer spacing gradually changes from 3mm at the inlet end to 5mm at the outlet end to form a guided eddy current, and the coaxiality is controlled within 0.5mm. The system realizes the graded capture of magnetic dust through the dynamic magnetic field of the permanent magnet array and the double-layer structure of the guide plate, which significantly improves the separation efficiency.
