Description

Technical Field

[0001] This utility model relates to the technical field of water drilling equipment, specifically a screening device for water drilling equipment. Background Technology

[0002] In the rhinestone processing industry, the products produced after precision grinding by rhinestone processing equipment typically include hot melt adhesive, rhinestones, and the adhesive between the hot melt adhesive and the rhinestones. To achieve effective separation of the rhinestones, existing technologies mainly rely on chemical treatment methods. Specifically, chemical agents are used to dissolve the hot melt adhesive in the material and the hot melt adhesive on the adhesive, thereby cleaning the rhinestones out of the material. Since the amount of chemical agent used is proportional to the amount of material, directly treating the material coming out of the rhinestone processing equipment with chemical agents will have the following problems: (1) High cost. As the scale of production expands, the amount of chemical agents used also increases, directly pushing up production costs. (2) Environmental impact. The use of large amounts of chemical agents not only increases the difficulty of wastewater treatment but may also lead to environmental pollution, especially long-term pollution of soil and water sources. (3) Complex operation. The chemical treatment process requires precise control of the proportion of the agent and the reaction time, which places high demands on the professional skills of the operators and increases the complexity of training and operation. (4) Waste of resources. Since hot melt adhesive is a recyclable and reusable material, failure to effectively recycle hot melt adhesive results in material waste and increases the cost of waste disposal.

[0012] Optionally, the receiving cavity is constructed as a frustum, and in the first direction, the cross-sectional area of ​​the receiving cavity gradually decreases in the direction away from the filter cavity.

[0013] Optionally, the screening device further includes an adsorption element, and the support includes a support body, a first support frame, and a second support frame;

[0014] The main body of the support includes a top frame, and a first side frame and a second side frame disposed opposite to each other on the top frame. The first support frame and the second support frame are disposed opposite to each other and connected to the top of the top frame. The storage cavity is located between the first support frame and the second support frame.

[0015] The first support frame has a groove with a first opening facing upwards, and the second support frame is provided with a retaining ring opposite to the groove;

[0016] A first rotating shaft is provided at one end of the storage cavity, and a second rotating shaft is provided at the other end of the storage cavity. The first rotating shaft is inserted into the retaining ring, and the second rotating shaft is rotatably accommodated in the groove.

[0017] The adsorption element is installed on the second end of the telescopic rod, the elastic element is connected between the bottom of the adsorption element and the top of the top frame, and the bottom of the filter chamber is detachably connected to the second end of the telescopic rod through the adsorption element.

[0018] Optionally, the number of adsorption elements is multiple, and the multiple adsorption elements are spaced apart along the second direction;

[0037] like Figures 1 to 3As shown, this disclosure provides a screening device for water drilling equipment, including a filter element 10, a box body 20, and a support 30. The box body 20 is mounted on the support 30 and is arranged at an angle. A cavity 21 is provided inside the box body 20. The cavity 21 includes a filter cavity 211 and a receiving cavity 212 that are connected to each other. The inlet of the filter cavity 211 is located below the outlet of the hopper 40. The filter cavity 211 has a first outlet 2111 and a second outlet 2112. The receiving cavity 212 has a third outlet 2121. The second discharge port 2112 is connected to the inlet of the receiving cavity 212. The top of the receiving cavity 212 is set as an open end, and the bottom of the receiving cavity 212 is set as a closed end. The open end is the third discharge port 2121. The filter element 10 is set at the first discharge port 2111 so that a portion of the material falling onto the filter element 10 can enter the receiving cavity 212 in sequence through the second discharge port 2112 and the inlet of the receiving cavity 212. Among them, a portion of the material is material that cannot pass through the filter element 10.

[0038] The filter element 10 is located at the first discharge port 2111 and is used to screen materials. The filter element 10 can block a portion of the material (smaller materials such as fine hot melt adhesive) from passing through the first discharge port 2111, while allowing another portion of the material (larger objects such as complete rhinestones or adhesives) to pass through the first discharge port 2111.

[0039] The box 20 is mounted on the support 30 and arranged at an inclined angle, which can promote the flow of materials by gravity and reduce the possibility of blockage.

[0040] The filter chamber 211 has an inlet (receiving material from the hopper 40), a first outlet 2111 (with a filter element 10), and a second outlet 2112. After the material enters the filter chamber 211, fine hot melt adhesive fragments can be discharged from the first outlet 2111 through the filter element 10, while the water drill or adhesive will be guided to the second outlet 2112.

[0041] The top of the receiving cavity 212 is open (serving as the third discharge port 2121), and the bottom is closed. The second discharge port 2112 is connected to the inlet of the receiving cavity 212, allowing water drills or adhesives that cannot pass through the filter element 10 to enter the receiving cavity 212 for collection.

[0042] Through the above technical solution, the box 20 and filter element 10 are configured. The box 20 has a cavity 21, which is divided into a filter cavity 211 and a collection cavity 212. The material first falls from the outlet of the hopper 40, enters the filter cavity 211, and is divided into two parts. One part is the larger material that cannot pass through the filter element 10 (such as whole rhinestones or adhesives). This part of the material can enter the collection cavity 212 through the second discharge port 2112. The other part is the smaller material that can pass through the filter element 10 (such as fine hot melt adhesive). This part of the material can be discharged from the first discharge port 2111 and collected by a collection container for subsequent recycling. In addition, the larger material in the collection cavity 212 can be poured out through the open end (third discharge port 2121) for subsequent chemical treatment to dissolve and separate the rhinestones and adhesives. The screening device disclosed herein can achieve multi-stage separation, that is, before using chemical agents to treat materials, hot melt adhesive can be preferentially screened out from water drills and adhesives for recycling through physical separation methods. This not only reduces the amount of chemical agents used, but also reduces the risk of environmental pollution, and improves resource utilization.

[0043] It should be noted that the inlet of the filter chamber 211 is connected to the third outlet 2121 of the receiving chamber 212.

[0044] As one implementation method, such as Figures 1 to 3 As shown, the screening device also includes a vibration assembly 50. One end of the receiving cavity 212 away from the filter cavity 211 is rotatably connected to the support 30. One end of the vibration assembly 50 is detachably connected to the filter cavity 211, and the other end of the vibration assembly 50 is connected to the support 30. The vibration assembly 50 includes a telescopic rod 51 and an elastic element 52. The elastic element 52 is sleeved on the telescopic rod 51. The first end of the telescopic rod 51 is connected to the top of the support 30, and the second end of the telescopic rod 51 is connected to the bottom of the filter cavity 211.

[0045] The telescopic rod 51 can serve as a support structure that provides an adjustable length, allowing the filter chamber 211 to move up and down relative to the bracket 30.

[0046] The elastic element 52 can be a spring structure, sleeved on the outside of the telescopic rod 51. The elastic element 52 can generate a certain elastic force when subjected to pressure or tension.

[0047] By combining the elastic element 52 (such as a spring) and the telescopic rod 51, the elastic element 52 can provide an upward thrust, which allows the filter chamber 211 to float to a certain extent in the vertical direction. This not only provides good shock absorption, but also significantly improves the screening effect and promotes the rapid entry of larger materials into the receiving chamber 212.

[0048] Specifically, the vibration assembly 50 can effectively absorb and mitigate vibrations generated during material flow or equipment operation, thereby protecting the entire screening device and its internal components. That is, when a large amount of material falls into the filter chamber 211, the downward pressure generated by gravity compresses the elastic element 52. At this time, the elastic element 52 can provide a reverse thrust, effectively absorbing vibrations and maintaining the stability of the equipment.

[0049] Furthermore, the presence of the vibration component 50 allows the filter chamber 211 to float to a certain extent in the vertical direction. Through vertical floating, the filter chamber 211 can vibrate up and down within a small range, which helps the material to be distributed more evenly on the filter element 10, thereby increasing the contact area and improving screening efficiency. At the same time, slight vibration can prevent material accumulation or clogging of the filter element 10, ensuring a smoother screening process.

[0050] Furthermore, due to the vertical floating of the filter chamber 211, larger materials (such as rhinestones or adhesives) are more likely to slide along the inclined angle towards the second discharge port 2112 and enter the receiving chamber 212 when subjected to slight vibration. This design can accelerate the separation and movement of materials and help loosen the bonds between materials, especially for larger particles that are prone to getting stuck due to their irregular shape, allowing them to pass more smoothly through the second discharge port 2112 into the receiving chamber 212.

[0051] As one implementation method, such as Figure 1 As shown, the height of the end of the filter cavity 211 away from the storage cavity 212 is higher than the height of the end of the storage cavity 212 away from the filter cavity 211.

[0052] With the bracket 30 as a reference, the height of the end of the filter chamber 211 away from the storage chamber 212 is always higher than the height of the end of the storage chamber 212 away from the filter chamber 211, regardless of the state of the elastic element 52.

[0053] When the material does not fall into the filter chamber 211, the elastic element 52 is in a natural state or a slightly pre-compressed state. At this time, the height of the end of the filter chamber 211 away from the receiving chamber 212 is A1, the height of the end of the receiving chamber 212 away from the filter chamber 211 is B1, and the height of the end of the filter chamber 211 away from the receiving chamber 212 is higher than the height of the end of the receiving chamber 212 away from the filter chamber 211, with a height difference of C1.

[0054] When the material enters the filtering cavity 211 and a downward pressure is applied, the elastic member 52 is in a compressed state. At this time, the height of the end of the filtering cavity 211 far from the storage cavity 212 is A2 (A2 < A1), the height of the end of the filtering cavity 211 far from the storage cavity 212 decreases, the height of the end of the storage cavity 212 far from the filtering cavity 211 is B2 (B2 > B1), the height of the end of the storage cavity 212 far from the filtering cavity 211 increases, and the height of the end of the filtering cavity 211 far from the storage cavity 212 is still higher than the height of the end of the storage cavity 212 far from the filtering cavity 211, and the height difference is C2.

[0055] When the elastic member 52 provides a reverse thrust (upward thrust), the height of the end of the filtering cavity 211 far from the storage cavity 212 is A3 (A3 > A1), the height of the end of the filtering cavity 211 far from the storage cavity 212 increases, the height of the end of the storage cavity 212 far from the filtering cavity 211 is B3 (B3 < B1), the height of the end of the storage cavity 212 far from the filtering cavity 211 decreases, and the height of the end of the filtering cavity 211 far from the storage cavity 212 is still higher than the height of the end of the storage cavity 212 far from the filtering cavity 211, and the height difference is C3.

[0056] That is to say, C2 < C1 < C3.

[0057] The state change of the elastic member 52 enables the screening device to automatically adjust its working posture according to the actual load, which can enhance the adaptability of the device to different working conditions. Moreover, by dynamically adjusting the inclination angle, the fluidity of the material can be improved, the speed of larger-sized materials entering the storage cavity 212 can be accelerated, and the screening accuracy can be ensured at the same time. In addition, since the possibility of material accumulation is reduced, the cleaning frequency and difficulty can be lowered, and the service life of the device can be indirectly extended.

[0058] As an implementation manner, as Figure 1 shown, the storage cavity 212 is configured as a frustum structure, and in the first direction (as Figure 1 shown), the cross-sectional area of the storage cavity 212 gradually decreases in the direction away from the filtering cavity 211.

[0059] The first direction can be understood as the direction away from the filtering cavity 211.

[0060] Because the cross-sectional area of ​​the receiving cavity 212 gradually decreases towards the direction away from the filtering cavity 211, a natural guiding slope can be formed. This helps the material slide more smoothly towards the bottom or outlet of the receiving cavity 212 under gravity. Furthermore, the conical design can accelerate the movement of larger materials (such as rhinestones or unseparated adhesives) towards the bottom of the receiving cavity 212 (specifically, the end of the receiving cavity 212 away from the filtering cavity 211), thereby improving the efficiency of the entire screening process. Additionally, when materials enter the receiving cavity 212, the conical structure helps them distribute more evenly within the cavity, avoiding blockages caused by localized overcrowding.

[0061] As one implementation method, such as Figures 1 to 3 As shown, the screening device also includes an adsorption element 60. The support 30 includes a support body 31, a first support frame 32, and a second support frame 33. The support body 31 includes a top frame 311 and a first side frame 312 and a second side frame 313 disposed opposite to each other on the top frame 311. The first support frame 32 and the second support frame 33 are disposed opposite to each other and connected to the top of the top frame 311. The receiving cavity 212 is located between the first support frame 32 and the second support frame 33. A first opening upward-facing groove 34 is formed on the first support frame 32. The second support... The frame 33 is provided with a retaining ring 35 opposite to the groove 34. One end of the storage cavity 212 is provided with a first rotating shaft 71, and the other end of the storage cavity 212 is provided with a second rotating shaft 72. The first rotating shaft 71 is inserted into the retaining ring 35, and the second rotating shaft 72 is rotatably accommodated in the groove 34. The adsorption member 60 is installed on the second end of the telescopic rod 51. The elastic member 52 is connected between the bottom of the adsorption member 60 and the top of the top frame 311. The bottom of the filter cavity 211 can be detachably connected to the second end of the telescopic rod 51 through the adsorption member 60.

[0062] Because the receiving cavity 212 has a first rotating shaft 71 at one end and a second rotating shaft 72 at the other end, with the first rotating shaft 71 inserted into a retaining ring 35 and the second rotating shaft 72 rotatably accommodated in a groove 34, one end of the receiving cavity 212 is inserted into the retaining ring 35 on the second support frame 33 via the first rotating shaft 71, ensuring that this end can rotate around the retaining ring 35. The other end of the receiving cavity 212 is rotatably accommodated in the groove 34 on the first support frame 32 via the second rotating shaft 72. This not only enables rotation but also gives the receiving cavity 212 a certain degree of spatial freedom, enhancing the adaptability of the screening device to different working conditions. Furthermore, due to the design of the first rotating shaft 71 and the second rotating shaft 72, the receiving cavity 212 can be quickly detached from the bracket 30. In other words, through the mutual cooperation between the first rotating shaft 71 and the retaining ring 35, and the second rotating shaft 72 and the groove 34, not only can the storage cavity 212 and the bracket 30 be rotatably connected, but also detachably connected. Furthermore, since the bottom of the filter cavity 211 can be detachably connected to the second end of the telescopic rod 51 via the suction member 60, the entire box 20 can be quickly installed on or removed from the bracket 30 for easy routine maintenance.

[0063] It should be understood that when the material (rhinestones, hot melt adhesive and the adhesive for rhinestones) in the storage cavity 212 reaches a certain amount, the operator can remove the box 20 from the support 30 and pour out the material in the storage cavity 212 through the third discharge port 2121.

[0064] As one implementation method, such as Figures 1 to 2 As shown, there are multiple adsorption elements 60, which are spaced apart along the second direction. The number of vibration components 50 corresponds one-to-one with the number of adsorption elements 60.

[0065] Multiple adsorption elements 60 along the second direction (e.g.) Figure 1 The spacing shown ensures that the bottom of the filter chamber 211 receives uniform adsorption and support at all positions, which helps maintain the stability of the entire box 20 (filter chamber 211).

[0066] The first direction and the second direction are set at an angle.

[0067] In one embodiment, the adsorption member 60 is constructed as a magnetic adsorption member 60, and the bottom of the filter cavity 211 is made of a magnetic material so that the bottom of the filter cavity 211 can attract the magnetic adsorption member 60.

[0068] Since the bottom of the filter chamber 211 is made of magnetic material, the bottom of the filter chamber 211 can directly attract the magnetic adsorption member 60, which helps to improve the flexibility of the connection between the adsorption member 60 and the filter chamber 211.

[0069] In another embodiment, a magnetic part is provided at the bottom of the filter chamber 211, which can attract the magnetic adsorption member 60.

[0070] Since the bottom of the filter chamber 211 is equipped with a magnetic part, it can be ensured that the magnetic part and the magnetic adsorption component 60 are automatically aligned when in contact, which can avoid manual adjustment of the installation position, thereby achieving precise positioning and improving installation efficiency.

[0071] As one implementation method, such as Figures 1 to 2 As shown, the screening device also includes a recycling box 80 and multiple wheels 90. The top frame 311, the first side frame 312, and the second side frame 313 together define a receiving space 314, which is used to receive the recycling box 80. The recycling box 80 is located below the filter chamber 211. The recycling box 80 has a second opening upward recycling chamber 81. The projection of the filter chamber 211 in the vertical direction is located inside the recycling chamber 81. Multiple wheels 90 are arranged at the bottom of the recycling box 80.

[0072] Since the recycling box 80 is located below the filter chamber 211, and the recycling chamber 81 of the recycling box 80 is aligned with the vertical projection of the filter chamber 211, the hot melt adhesive falling from the filter chamber 211 falls directly into the recycling chamber 81, which can reduce the risk of hot melt adhesive scattering.

[0073] Multiple wheels 90 are located at the bottom of the recycling box 80, allowing the recycling box 80 to be easily pulled out or pushed in from the receiving space 314. This not only facilitates daily maintenance and cleaning but also makes it easier to transport the recycled materials to a designated location for water-drilling separation.

[0074] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0075] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0076] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
