Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and more specifically, it relates to a waste collection device for testing laboratories. Background Technology

[0002] As the core location for scientific research, product testing, and medical experiments, testing laboratories generate a large amount of waste during their daily operations, including experimental waste liquids and solid wastes. Existing waste collection devices for testing laboratories are often used by attaching an adhesive layer at one end of the mounting base to the wall or workbench.

[0003] Existing laboratory waste collection systems have been found to have the following issues during use: 1. Most existing waste bins are single open chambers, where liquid and solid waste are directly mixed and collected. This requires manual separation of the mixed solid and liquid waste, which increases the workload and results in poor practicality.

[0004] 2. The existing installation methods for waste bins and mounting bases have poor stability. Waste bins are prone to tipping over due to slight collisions or vibrations of laboratory equipment, resulting in waste leakage and thus poor practicality.

[0005] 3. Most of them are deep-cavity straight-cylinder structures, and residual waste is easy to accumulate at the bottom and corners of the chamber. It is difficult for staff to clean them quickly, and multiple cleanings are required, which increases the workload and thus leads to poor practicality. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a waste collection device for testing laboratories to solve the technical problems mentioned in the background art, such as the lack of effective dry and wet separation function, poor connection stability between waste bin and mounting base, and difficulty in cleaning the inside of waste bin.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a waste collection device for a testing laboratory, comprising a mounting base, a mounting frame at the top front end of the mounting base, a waste bin fitted inside the mounting frame, an annular baffle at the top outer side of the waste bin, the bottom of the annular baffle being in close contact with the top of the mounting frame, a fixing mechanism at the bottom front end of the mounting base, the front end of the mounting base being connected to the rear end of the waste bin via the fixing mechanism, the waste bin having a chamber, a filter plate in the central area of ​​the chamber, an arc-shaped hole at the bottom front end of the chamber, a semi-arc plate inside the arc-shaped hole, a collection box at the rear end of the semi-arc plate, the outer side of the collection box being in close contact with the inner side of the chamber, positioning components on both sides of the semi-arc plate, and the semi-arc plate being connected to the waste bin via the positioning components.

[0008] The present invention is further configured such that the fixing mechanism includes two sets of clamping plates, a sliding groove is provided at the bottom front end of the mounting base, a bidirectional screw is rotatably disposed in the sliding groove of the mounting base, and a first slider is threadedly connected to both ends of the outer side of the bidirectional screw, and both sets of the first sliders are slidably connected to the sliding groove of the mounting base, a connecting block is provided at the front end of each set of the first sliders, a clamping plate is provided at the front end of each set of the connecting blocks, and a first locking block is provided at the front end of each set of the clamping plates, and a locking groove is provided on both sides of the bottom rear end of the waste bin, and the front ends of the two sets of the first locking blocks are connected to the waste bin. The waste bin is secured in a slot, and the left end of the bidirectional screw passes through the mounting base groove and is equipped with an auxiliary component. The bidirectional screw drives two sets of clamping plates to clamp synchronously. The first locking block and the slot form a mechanical lock, avoiding the loosening problem of traditional adhesive fixing. Even if it is hit, it is not easy to tip over. The forward and reverse rotation of the bidirectional screw achieves quick locking and unlocking, replacing the individual tightening of bolts. This greatly simplifies the process of replacing or cleaning waste bins, improves operational efficiency, and the adjustment range of the bidirectional screw can adapt to waste bins of different sizes. There is no need to change the fixing mechanism due to changes in waste bin specifications, making it highly versatile.

[0009] The present invention is further configured such that the auxiliary component includes a connecting gear and a knob, the knob is rotatably mounted on the bottom left end of the mounting base, the knob has a groove on its right end face, and toothed blocks are evenly arranged on the inner wall of the knob groove. The left end of the bidirectional screw passes through the mounting base slide groove and enters the knob groove, and the connecting gear is provided on the left outer end of the bidirectional screw, and the outer side of the connecting gear meshes with the toothed blocks. The knob increases the area for hand force application, and the hand force is transmitted to the bidirectional screw through gear meshing transmission, which is more labor-saving than directly rotating the screw. There is no slippage in the meshing transmission between the toothed blocks and the connecting gear, and the rotation amplitude of the knob strictly corresponds to the rotation angle of the bidirectional screw, which facilitates precise control of the clamping degree of the clamping plate.

[0010] The present invention is further configured such that the positioning component includes two sets of L-shaped blocks and two sets of mounting blocks. L-shaped plates are provided on both the left and right sides of the semi-arc plate. Each set of L-shaped blocks has a slot at one end facing away from the other. A second locking block is provided within each slot of the two sets of L-shaped blocks. A mounting block is provided at one end of each set of second locking blocks. Fixing blocks are provided on both the left and right sides of the waste bin. A sliding groove is provided at one end of each set of fixing blocks. A second slider is slidably connected within each sliding groove of the two sets of fixing blocks. Support rods are provided on both the front and rear sides of one end of each set of second sliders via hinges. Telescopic rods are provided at the top of one end of each set of fixing blocks. The other ends of each set of telescopic rods are connected to the top of one end of a mounting block. Furthermore, each set of mounting blocks is connected to a support rod at one end of the other via hinges. The other ends of the two sets of support rods are connected, and the bottom of the sliding grooves of the two sets of fixing blocks are provided with reserved holes. Sliding rods are slidably connected in the reserved holes of the two sets of fixing blocks. The top of the two sets of sliding rods is connected to the bottom of a set of second sliding blocks, and elastic components are provided on the outer side of the two sets of sliding rods. Arc-shaped sliding plates are provided at the bottom of the two sets of sliding rods. The rear end of the arc-shaped sliding plate slides tightly against the bottom of the front end of the waste bin. The elastic components provide continuous elastic force to make the second locking block tightly embedded in the slot. With the support of the telescopic rod and the support rod, it is ensured that the semi-arc plate will not loosen when the device is running, avoiding liquid leakage in the collection box. The semi-arc plate can be quickly unfixed by pressing the arc-shaped sliding plate without the need for tools. Compared with traditional bolt fixing, this greatly simplifies the cleaning process of the collection box and improves the operating efficiency.

[0011] The present invention is further configured such that the elastic component includes a connecting spring, and a connecting spring is provided on the outer side of both sets of slide rods. Both ends of the two sets of connecting springs are connected to the bottom of the second slider and the bottom of the groove of the fixed block. The elastic action of the connecting spring ensures that the second locking block is always tightly fitted with the groove of the L-shaped block, avoiding positioning loosening due to vibration or slight collision, ensuring reliable fixing of the semi-arc plate, and the change of elastic force during compression and reset provides the operator with clear tactile feedback, making it easy to judge whether the positioning component is completely locked or unlocked, and improving the accuracy of operation.

[0012] The present invention is further configured such that an annular guide plate is provided in the chamber, and the annular guide plate is located between the filter plate and the collection box; this guides the liquid to flow in a directional manner, avoids the liquid from splashing randomly or remaining on the chamber wall, ensures that more liquid enters the collection box, and reduces the amount of cleaning work.

[0013] The present invention is further provided with a handle at the front end of the semi-circular plate; the handle provides a stable grip point, which is easier to apply force than pulling the semi-circular plate directly, and can significantly reduce the difficulty of pulling it out, especially when the collection box is full of liquid and the weight increases.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a waste collection device for testing laboratories, which has the following beneficial effects: 1. The combination of filter plates and collection boxes physically separates liquid and solid waste, avoiding mixed contamination, complying with laboratory classification standards, and reducing the difficulty and safety risks of subsequent treatment.

[0015] 2. The dual fixing of the mounting bracket and the fixing mechanism replaces the traditional adhesive or single bolt connection, which not only prevents the waste bin from tipping over, but also enables quick assembly and disassembly through the fixing mechanism, solving the problems of cumbersome connection and poor stability.

[0016] 3. The pull-out design of the semi-circular plate and collection box allows for the disposal of liquid waste without having to overturn the entire waste bin, while solid waste can be directly disposed of through the top opening. The overall structure facilitates thorough cleaning of internal residues. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] Please see Figure 1-5 A waste collection device for a testing laboratory includes a mounting base 1, a mounting frame 2 at the top front end of the mounting base 1, a waste bin 3 fitted inside the mounting frame 2, an annular baffle 4 at the top outer side of the waste bin 3, the bottom of the annular baffle 4 being in close contact with the top of the mounting frame 2, a fixing mechanism at the bottom front end of the mounting base 1, the front end of the mounting base 1 being connected to the rear end of the waste bin 3 through the fixing mechanism, a chamber 5 being provided in the waste bin 3, a filter plate 6 being provided in the central area of ​​the chamber 5, an arc-shaped hole at the bottom front end of the chamber 5, a semi-arc plate 7 being provided inside the arc-shaped hole of the chamber 5, a collection box 27 being provided at the rear end of the semi-arc plate 7, the outer side of the collection box 27 being in close contact with the inner side of the chamber 5, positioning components being provided on both the left and right sides of the semi-arc plate 7, and the semi-arc plate 7 being connected to the waste bin 3 through the positioning components.

[0023] In this embodiment, the waste bin 3 is fitted inside the mounting bracket 2 at the top front end of the mounting base 1. The annular baffle 4 at the top outer side of the waste bin 3 moves down until it is in close contact with the top of the mounting bracket 2. By operating the fixing mechanism at the bottom front end of the mounting base 1, the fixing mechanism is connected to the rear end of the waste bin 3 to complete the fixation, and it can be used. When in use, after the laboratory waste is put into the chamber 5 of the waste bin 3, it first contacts the filter plate 6 in the central area. Liquid waste seeps downward through the pores of the filter plate 6, while solid waste is intercepted above the filter plate 6, achieving preliminary dry and wet separation. The seeping liquid waste flows along the wall of the chamber 5 and finally enters the collection box 27 at the rear end of the semi-arc plate 7 (the outer side of the collection box 27 is in close contact with the inner side of the chamber 5 to avoid liquid leakage). Solid waste remains above the filter plate 6, completing the classification and temporary storage. When cleaning is required, the positioning component is adjusted to disconnect it from the semi-arc plate 7, and then the semi-arc plate 7 is pulled, so that the semi-arc plate 7 drives the collection box 27 out of the chamber 5 of the waste bin 3, and then cleaning can be performed.

[0024] More specifically, when cleaning is required, press down on the arc-shaped sliding plate 24 to drive the sliding rod 23 to slide down along the reserved hole of the fixing block 19. The second slider 20 at the top of the sliding rod 23 compresses the elastic component and moves down along the slide groove. The second slider 20 pulls the mounting block 17 away from the L-shaped block 16 through the support rod 21. At the same time, the telescopic rod 22 retracts, and the second locking block 18 exits from the locking groove of the L-shaped block 16. The constraint between the semi-arc plate 7 and the waste bin 3 is released. Then, pull the semi-arc plate 7 to complete the disassembly of the semi-arc plate 7 and the collection box 27.

[0025] Please see Figure 1 and Figure 4 As one embodiment of the fixing mechanism: the fixing mechanism includes two sets of clamping plates 8, a sliding groove is provided at the bottom front end of the mounting base 1, a bidirectional screw 9 is rotatably disposed in the sliding groove of the mounting base 1, and the two outer ends of the bidirectional screw 9 are threadedly connected to the first slider 10, and both sets of the first slider 10 are slidably connected to the sliding groove of the mounting base 1, a connecting block 11 is provided at the front end of both sets of the first slider 10, a clamping plate 8 is provided at the front end of both sets of the connecting block 11, and a first locking block 13 is provided at the front end of both sets of the clamping plates 8, a locking groove is provided on both sides of the bottom rear end of the waste bin 3, the front ends of both sets of the first locking blocks 13 are engaged with the locking groove of the waste bin 3, and an auxiliary component is provided at the left end of the bidirectional screw 9 passing through the sliding groove of the mounting base 1.

[0026] Specifically, after the waste bin 3 is placed on the mounting bracket 2, the bidirectional screw 9 in the slide groove of the mounting base 1 is driven to rotate by the auxiliary component. Due to the threaded connection, the first sliders 10 at both ends of the outer side of the bidirectional screw 9 slide in opposite directions along the slide groove. The connecting block 11 at the front end of the first slider 10 drives the clamping plate 8 to move synchronously until the first locking block 13 at the front end of the clamping plate 8 is embedded in the locking grooves on both sides of the bottom rear end of the waste bin 3. At this time, the two sets of clamping plates 8 clamp the waste bin 3 from both sides, and the first locking block 13 and the locking groove form a limit, firmly fixing the waste bin 3 on the mounting base 1, thus completing the installation and fixing of the waste bin 3. Please refer to Figures 2-4 As a further embodiment of the auxiliary component: the auxiliary component includes a connecting gear 14 and a knob 15. The knob 15 is rotatably disposed at the bottom left end of the mounting base 1. A groove is provided on the right end face of the knob 15. Tooth blocks are evenly disposed on the inner wall of the groove of the knob 15. The left end of the bidirectional screw 9 passes through the slide groove of the mounting base 1 and enters the groove of the knob 15. The connecting gear 14 is disposed on the left outer end of the bidirectional screw 9, and the outer side of the connecting gear 14 meshes with the tooth blocks.

[0027] Specifically, manually rotate the knob 15 at the bottom left end of the mounting base 1. Because the connecting gear 14 and the gear in the groove of the knob 15 are meshed, the tooth block drives the connecting gear 14 to rotate through meshing transmission, thereby driving the bidirectional screw 9 to rotate synchronously, and the two sets of first sliders 10 begin to slide.

[0028] In summary, the overall equipment is in use (or running): Place the waste bin 3 inside the mounting bracket 2 at the top front end of the mounting base 1. The annular baffle 4 on the top outer side of the waste bin 3 will then move down until it is in close contact with the top of the mounting bracket 2. Manually rotate the knob 15 at the bottom left end of the mounting base 1. Because the connecting gear 14 and the gear in the groove of the knob 15 are meshed, the toothed block drives the connecting gear 14 to rotate through meshing transmission, which in turn drives the bidirectional screw 9 to rotate synchronously. The two sets of first sliders 10 begin to slide. The connecting block 11 at the front end of the first slider 10 drives the clamping plate 8 to move synchronously until the first locking block 13 at the front end of the clamping plate 8 is embedded in the locking grooves on both sides of the bottom rear end of the waste bin 3. At this time, the two sets of clamping plates 8 clamp the waste bin 3 from both sides. The first locking block 13 and the locking groove form a limit, firmly fixing the waste bin 3 on the mounting base 1, thus completing the installation and fixing of the waste bin 3.

[0029] When in use, laboratory waste is put into the chamber 5 of the waste bin 3 and first comes into contact with the filter plate 6 in the central area. Liquid waste seeps downward through the pores of the filter plate 6, while solid waste is intercepted above the filter plate 6, achieving preliminary dry and wet separation. The seeping liquid waste is guided by the annular guide plate 26 and finally enters the collection box 27 at the rear end of the semi-arc plate 7, while solid waste remains above the filter plate 6, completing the classification and temporary storage.

[0030] When cleaning is required, press down on the arc-shaped sliding plate 24 to drive the sliding rod 23 to slide down along the reserved hole of the fixing block 19. The second slider 20 at the top of the sliding rod 23 compresses the connecting spring 25 and moves down along the slide groove. The second slider 20 pulls the mounting block 17 away from the L-shaped block 16 through the support rod 21. At the same time, the telescopic rod 22 retracts, and the second locking block 18 exits from the locking groove of the L-shaped block 16. The constraint between the semi-arc plate 7 and the waste bin 3 is released. Then, pull the semi-arc plate 7 through the handle 12 to complete the disassembly of the semi-arc plate 7 and the collection box 27, and then clean it.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
