Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a novel vacuum filtration device. Background Technology

[0002] Vacuum filtration devices, also known as vacuum filters, generally consist of a funnel and a collection bottle. The liquid to be filtered is stored in the funnel, and the receiving bottle is connected to the vacuum equipment with a discharge valve at the bottom. The funnel contains filter media and is connected directly above the receiving bottle. It works in conjunction with the vacuum equipment to perform filtration. It can be used for reactions at room temperature and uses vacuum negative pressure as the driving force to separate liquids. It achieves high-efficiency filtration under negative pressure conditions and is widely used in laboratories and industrial production.

[0003] Currently used vacuum filters are mostly fixed-height devices, which greatly limits the operator's control over feeding materials into the funnel and selecting the discharge space, making them inconvenient for operators of different heights.

[0004] Based on this, this utility model designs a novel vacuum filtration device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a novel vacuum filtration device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel vacuum filtration device, comprising: a base, a lifting mechanism, and a filtration mechanism;

[0007] The lifting mechanism includes a bracket, a connecting frame slidably connected to one side of the bracket, a motor fixed to the top of the base, a reel driven by the motor, a pull rope fixed between one end of the connecting frame and the reel, and a suction filter mechanism installed through the connecting frame to assist its up and down movement.

[0008] The filtration mechanism includes a mounting frame, a funnel fixed to the outer wall of the mounting frame, a receiving bottle detachably connected to the bottom of the funnel, and two symmetrical stabilizing parts disposed at one end of the connecting frame to assist in stabilizing the receiving bottle during operation.

[0009] Preferably, the stabilizing part at one end of the connecting frame includes a support fixed to the outer wall of the connecting frame, a threaded rod threaded to one end of the support, a support plate rotatably connected to one end of the threaded rod, and a handle fixed to the end of the threaded rod away from the support plate.

[0010] Preferably, the trays of the two stabilizing parts are respectively clamped to the bottom of the receiving bottle.

[0011] Preferably, the bracket is fixed to the top of the base, one end of the bracket is rotatably connected to a guide wheel, and the pull rope between the reel and the connecting frame contacts and is connected and pulled through the guide wheel.

[0012] Preferably, a transparent plate is rotatably connected to the outer wall of the mounting frame, and bolts are used to lock the transparent plate to the mounting frame.

[0013] Preferably, the base is provided with multiple casters at its bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the height of the entire filtration mechanism can be adjusted by a lifting mechanism, so that when personnel need to feed materials, the funnel is positioned at a low position for easy feeding. When a container needs to be placed under the receiving bottle, the entire filtration mechanism is moved upward to leave more space for placement, reducing the limitations of funnel feeding and selecting the discharge space, and also making it easier for people of different heights to operate and use.

[0016] Secondly, since the receiving bottles need to be replaced frequently, the stabilizing part of this device for stabilizing the receiving bottles can be adjusted. By rotating the threaded rod, the trays can be moved closer or further apart, thus making it suitable for receiving bottles of more sizes.

[0017] Thirdly, when performing vacuum filtration, personnel can stand in front of a transparent plate to separate the receiving bottle, allowing them to observe the contents of the receiving bottle more safely and determine whether the filtrate has achieved the expected results.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a novel vacuum filtration device, comprising: a base 1, a lifting mechanism, and a filtration mechanism;

[0027] The lifting mechanism includes a bracket 2, a connecting frame 3 slidably connected to one side of the bracket 2, a motor 7 fixed to the top of the base 1, a roller 8 driven by the motor 7, and a pull rope 9 fixed between one end of the connecting frame 3 and the roller 8. The suction filter mechanism is installed through the connecting frame 3 to assist its up and down movement.

[0028] The filtration mechanism includes a mounting frame 4, a funnel 5 fixed to the outer wall of the mounting frame 4, a receiving bottle 6 detachably connected to the bottom of the funnel 5, and two symmetrical stabilizing parts set at one end of the connecting frame 3, which assist the receiving bottle 6 in stabilizing the operation.

[0029] The filtration mechanism is installed on the connecting frame 3 of the lifting mechanism. The motor 7 can control the rotation of the winding wheel 8 to wind and unwind the pull rope 9, so that the bracket 2 can slide up and down under control, thereby driving the filtration mechanism to move, making it easier for personnel at different heights to operate and use. The funnel 5 and the receiving bottle 6 in the filtration mechanism are locked together with bolts. The funnel 5 is made of stainless steel for greater stability, and the receiving bottle 6 is made of transparent glass for easy observation and can be disassembled and replaced. After installation, the receiving bottle 6 is supported by the stabilizing part, making it more stable during operation.

[0030] More preferably, the stabilizing part at one end of the connecting frame 3 includes a support 11 fixed to the outer wall of the connecting frame 3, a threaded rod 12 threaded to one end of the support 11, a support plate 13 rotatably connected to one end of the threaded rod 12, and a handle 14 fixed at the end of the threaded rod 12 away from the support plate 13.

[0031] In the two stabilizing units, personnel can use the handle 14 to control the rotation of the threaded rod 12, and then use the threaded rod 12 to control the two trays 13 to move closer and further apart, in order to stabilize receiving bottles 6 of different sizes and capacities.

[0032] More preferably, the two stabilizing plates 13 are respectively clamped to the bottom of the receiving bottle 6;

[0033] The stabilizing plate 13 is attached to the bottom of the receiving bottle 6 in a grasping shape, and the two work together to clamp and stabilize the receiving bottle 6.

[0034] More preferably, the bracket 2 is fixed to the top of the base 1, and one end of the bracket 2 is rotatably connected to the guide wheel 10. The pull rope 9 between the reel 8 and the connecting frame 3 contacts and is connected and pulled through the guide wheel 10.

[0035] The guide wheel 10 at one end of the bracket 2 suspends the pull rope 9 and assists the pull rope 9 in being pulled and released more stably.

[0036] A further preferred embodiment has a transparent plate 15 rotatably connected to the outer wall of the mounting frame 4, and bolts are used to lock the transparent plate 15 to the mounting frame 4.

[0037] The transparent plate 15 of the mounting frame 4 can be rotated and opened, making it convenient for personnel to inspect, maintain and replace the receiving bottle 6 or the funnel 5.

[0038] Furthermore, the base 1 has multiple casters at its bottom;

[0039] The base 1 is equipped with casters to assist in moving and transferring the entire device.

[0040] One specific application of this embodiment is that personnel can control the rotation of the reel 8 through the motor 7 in the lifting mechanism to perform the winding or unwinding operation of the pull rope 9. When winding, one end of the pull rope 9 will pull the connecting frame 3 of the bracket 2 to move upward. When unwinding, the pull rope 9 will also release and cause the connecting frame 3 to move downward, thereby adjusting the height of the entire suction filter mechanism. When personnel need to feed materials, the position of the funnel 5 is at a low position to facilitate feeding. When it is necessary to place a container under the receiving bottle 6, the entire suction filter mechanism is moved upward to leave more space for placement, reducing the limitations of the feeding and discharge space of the funnel 5.

[0041] Laboratories or enterprises need to process a large number of liquid samples, requiring the use of receiving bottles 6 of different capacities. The stabilizing part is designed to accommodate receiving bottles 6 of various capacities. The two support plates 13 can be moved closer or further apart by rotating the threaded rod 12. Personnel can operate the rotation of the threaded rod 12 using the handle 14. During the filtration operation, personnel can stand in front of the transparent plate 15, which separates the receiving bottles 6, allowing for safer observation of the contents of the receiving bottles 6 and judgment of whether the filtrate has achieved the expected results.
