Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum filtration equipment, and in particular relates to a vacuum filtration bottle filtrate auxiliary pouring device. Background Technology

[0002] A vacuum filtration apparatus typically consists of a Buchner funnel, a filtration flask, tubing, a vacuum pump, and filter paper. In use, the outlet of the filtration flask is connected to the suction end of the vacuum pump via the tubing. The Buchner funnel is then placed inside the opening at the top of the filtration flask, and filter paper is placed inside. The material to be filtered is poured into the Buchner funnel, water is added, and the mixture is stirred. The vacuum pump is then turned on to begin filtration. After multiple filtrations, a significant amount of filtrate accumulates in the filtration flask, which needs to be poured out promptly before continuing filtration. Currently, the filtrate is poured out manually by lifting the filtration flask and tilting the top opening downwards. This method is labor-intensive, and because the filtration flask with filtrate is heavy, it is prone to slipping and breaking if it is lifted. Therefore, an improvement is necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides an auxiliary pouring device for filtrate from a vacuum filtration flask. Rotating the support plate upwards causes the vacuum filtration flask to rotate, improving the ease of pouring the filtrate and preventing the flask from slipping and breaking.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A device for assisting in the pouring of filtrate from a vacuum filtration flask includes:

[0006] A pair of vertical plates, each with symmetrical arc-shaped grooves on its inner side;

[0007] The support plate has a retaining ring on its top. The inner diameter of the retaining ring matches the outer diameter of the bottom of the filtration flask and is used to accommodate the bottom of the filtration flask. There are connecting posts on both sides of the retaining ring, and the two connecting posts are slidably connected to two arc-shaped grooves respectively.

[0008] The retaining ring is used to fix the neck of the filtration flask. There are connecting rods on both sides of the retaining ring. The two connecting rods are rotatably connected to a pair of vertical plates. The inner diameter of the retaining ring matches the outer diameter of the neck of the filtration flask. When the connecting column slides to the bottom of the arc-shaped groove, the connecting column is directly below the connecting rod. The center of the arc-shaped groove is on the axial direction of the connecting rod, and the height of the top of the arc-shaped groove is higher than the height of the connecting rod.

[0009] Furthermore, the fixing ring includes a first half-ring and a second half-ring. The first half-ring is connected to a connecting rod on its periphery, and the second half-ring is connected to another connecting rod on its periphery. One end of both the first half-ring and the second half-ring is provided with a connecting block. The two connecting blocks are connected by screws. Each of the pair of vertical plates is provided with a connecting hole, and the two connecting rods slide through the two connecting holes respectively.

[0010] Furthermore, each of the connecting rods has a baffle plate at the outward end. The diameter of the baffle plate is larger than the diameter of the connecting hole. When the first half-ring and the second half-ring abut, the two baffle plates abut against a pair of vertical plates respectively.

[0011] Furthermore, a connecting buckle is provided on the periphery of the retaining ring. The connecting buckle is connected to one end of a traction rope, and the other end of the traction rope is connected to a take-up and release mechanism. The take-up and release mechanism is located between a pair of vertical plates and is used to take up and release the traction rope, so that the connecting column moves along the arc-shaped slide groove.

[0012] Furthermore, the traction mechanism includes a drive motor, support rods, and a fixed base. The fixed base is fixed between a pair of vertical plates, and a rotating shaft is rotatably connected inside the fixed base. One end of the rotating shaft is connected to the output shaft of the drive motor. The support rods are spaced above the rotating shaft, and the height of the support rods is higher than the height of the connecting rods. The other end of the traction rope passes over the top of the support rods and is connected to the rotating shaft.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Rotating the support plate upwards will cause the filter flask to rotate, which improves the convenience of pouring the filtrate and prevents the filter flask from slipping and breaking.

[0015] 2. When it is necessary to pour out the filtrate, control the traction mechanism to retract the traction rope, which will drive the fixing ring and the filtration bottle to rotate upward along the arc-shaped slide through the connecting buckle, thereby realizing the automatic pouring of the filtrate.

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0023] This application provides an auxiliary pouring device for filtrate from a vacuum filtration flask, such as... Figures 1-4 As shown, it includes a vertical plate 1, a support plate 2, a fixing ring 4, etc.

[0024] Specifically, there is a pair of vertical plates 1, and the inner sides of each pair of vertical plates 1 are symmetrically provided with arc-shaped grooves 101; the top of the support plate 2 is provided with a retaining ring 201, the inner diameter of which matches the outer diameter of the bottom of the filtration flask 3, for accommodating the bottom of the filtration flask 3; both sides of the retaining ring 201 are provided with connecting posts 202, and the two connecting posts 202 are slidably connected in the two arc-shaped grooves 101 respectively; the fixing ring 4 is used to fix the neck 301 of the filtration flask 3. Specifically, the height of the fixing ring 4 is set to match the height of the vertically positioned... The neck 301 of the filtration bottle 3 inside the retaining ring 201 is height-matched. There are connecting rods 5 on both sides of the fixing ring 4. The two connecting rods 5 are rotatably connected to a pair of vertical plates 1 respectively. The inner diameter of the fixing ring 4 matches the outer diameter of the neck 301 of the filtration bottle 3. When the connecting column 202 slides to the bottom of the arc-shaped slide groove 101, the connecting column 202 is directly below the connecting rod 5. The center of the arc-shaped slide groove 101 is on the axial direction of the connecting rod 5. The height of the top of the arc-shaped slide groove 101 is higher than the height of the connecting rod 5.

[0025] In actual use, Figure 5The bottom of the filtration flask 3 shown is placed on the support plate 2. The retaining ring 201 will block the filtration flask 3 to prevent it from sliding out of the support plate 2. Specifically, a rubber sheet can be set inside the retaining ring 201 to prevent the filtration flask 3 from being crushed and to increase the friction between the inside of the retaining ring 201 and the bottom of the filtration flask 3, preventing the filtration flask 3 from detaching from the retaining ring 201 when it is pushed up. Then, the neck 301 of the filtration flask 3 is fixed in the fixing ring 4 to prevent the support plate 2 from rotating. When the filtration equipment has been used for a period of time and the filtrate in the filtration flask 3 reaches its maximum, the vacuum pump is turned off and the rubber tube and Buchner funnel are removed. The support plate 2 and the filtration flask 3 are pushed so that the connecting column 202 slides to the top of the arc-shaped chute 101 to pour out the filtrate. When pouring, a receiving cylinder can be placed below the fixing ring 4 to receive the filtrate. After the filtrate is completely poured out, the connecting column 202 is slid to the bottom of the arc-shaped chute 101 to reset the filtration flask 3.

[0026] For details, please refer to Figure 2 , Figure 3 The fixing ring 4 includes a first half-ring 401 and a second half-ring 402. The first half-ring 401 is connected to a connecting rod 5 around its periphery, and the second half-ring 402 is connected to another connecting rod 5 around its periphery. Each end of the first half-ring 401 and the second half-ring 402 is provided with a connecting block 403, and the two connecting blocks 403 are connected by screws 404. Each pair of vertical plates 1 has a connecting hole, and the two connecting rods 5 slide through the two connecting holes respectively. When fixing the filtration flask 3, the two connecting rods 5 can be pulled outwards first. After the filtration flask 3 is placed on the support plate 2, the two connecting rods 5 are pushed inwards, and then the first half-ring 401 and the second half-ring 402 are connected by screws 404 to complete the fixing. For more details, please refer to [link to relevant documentation]. Figure 2 Each connecting rod 5 has a baffle 501 at its outward-facing end. The diameter of the baffle 501 is larger than the diameter of the connecting hole. When the first half-ring 401 and the second half-ring 402 abut, the two baffles 501 abut against a pair of vertical plates 1 respectively. After the first half-ring 401 and the second half-ring 402 are connected, the two baffles 501 abut against a pair of vertical plates 1 respectively, which can prevent the connecting rod 5 from moving in the horizontal direction and improve the stability of the equipment.

[0027] Preferred options, please refer to Figure 3 , Figure 4The retaining ring 201 is provided with a connecting buckle 6 around its periphery. The connecting buckle 6 is connected to one end of a traction rope 7, and the other end of the traction rope 7 is connected to a winding mechanism. The winding mechanism is located between a pair of vertical plates 1 and is used to wind up and wind up the traction rope 7, so that the connecting column 202 moves along the arc-shaped slide 101. When it is necessary to pour the filtrate, the traction mechanism is controlled to wind up the traction rope 7, which will drive the fixing ring 4 and the suction bottle 3 to rotate upward along the arc-shaped slide 101 through the connecting buckle 6, thereby realizing automatic pouring. Specifically, the traction mechanism includes a drive motor 8, a support rod 801, and a fixed seat 802. The fixed seat 802 is fixed between a pair of vertical plates 1. A rotating shaft 803 is rotatably connected inside the fixed seat 802. One end of the rotating shaft 803 is connected to the output shaft of the drive motor 8. The support rod 801 is spaced above the rotating shaft 803. The height of the support rod 801 is higher than the height of the connecting rod 5. The other end of the traction rope 7 passes over the top of the support rod 801 and is connected to the rotating shaft 803. Controlling the drive motor 8 to rotate will drive the rotating shaft 803 to rotate, thereby realizing the raising and lowering of the traction rope 7. Since the height of the support rod 801 is higher than the height of the connecting rod 5, specifically, the height of the support rod 801 can be set to be higher than the connecting rod 5 by a preset distance. This allows the fixing ring 4 and the filtration bottle 3 to be pulled up to a certain tilt angle by the traction rope 7, so that the filtrate in the filtration bottle 3 can be completely poured out.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
