Description

Technical Field

[0001] This utility model relates to the field of sampling technology, specifically to an extractor used in the production of biodegradable membranes. Background Technology

[0002] The preparation process of biodegradable membranes typically includes steps such as raw material selection, modification and mixing, particle forming, membrane processing and post-treatment.

[0003] In the preparation of biodegradable membranes, quality testing is a crucial step. To ensure the quality of biodegradable membranes, it is necessary to extract and test the raw materials in each batch. However, the storage tanks currently in use can only extract granular raw material samples from the bottom discharge valve. The samples extracted from the bottom discharge valve often cannot represent the true situation of the entire batch of raw materials, and their representativeness is poor. This can lead to misjudgment of the raw material quality, which in turn affects the final quality of the biodegradable membrane.

[0004] Therefore, in order to solve the above problems, an extractor for the production of biodegradable membranes is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an extractor for the production of biodegradable membranes, which can extract raw material samples from storage tanks from multiple points, ensuring the accuracy of test results, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extractor for the production of biodegradable membranes, comprising a storage tank and a support frame fixedly installed together, a conveying pipe fixedly installed on the same side of the storage tank and the support frame, an extraction tube fixedly installed in the storage tank, one end of the extraction tube extending into the storage tank and the other end connected to the conveying pipe, a sampler installed inside the extraction tube, a power mechanism for driving the sampler installed in the conveying pipe, a bend rotatably installed at the lower end of the conveying pipe, and a swing mechanism for rotating the bend installed in the conveying pipe.

[0007] Specifically, the extraction tubes are 2 to 3 tubes evenly distributed along the axial direction of the delivery pipe.

[0008] Specifically, the sampler includes a rotating rod and a spiral blade. An integral spiral blade is fixedly installed on the circumferential side of the rotating rod. One end of the rotating rod passes through a conveying pipe, and the other end of the rotating rod passes through an extraction pipe and extends into a storage tank.

[0009] Furthermore, the diameter of the portion of the spiral blade extending into the storage tank gradually decreases as it moves away from the extraction tube.

[0010] Furthermore, a wear-resistant layer is fixedly installed on the inner circumference of the extraction tube, and the edge of the spiral blade abuts against the wear-resistant layer.

[0011] Specifically, the power mechanism includes a first geared motor and a linear bearing. The linear bearing is fixedly installed on the side of the conveying pipe away from the extraction pipe. The rotating rod is slidably installed inside the linear bearing. The first geared motor is fixedly installed on the side wall of the storage tank through a support platform. The output end of the first geared motor is connected and assembled to the rotating rod through a coupling.

[0012] Furthermore, a support ring is fixedly installed on the circumferential side of the right half-coupling in the coupling, and a wave track is opened on the end face of the support ring near the linear bearing. A guide wheel is rotatably installed on the upper side of the support platform, and the guide wheel abuts against the wave track.

[0013] Specifically, the swing mechanism includes a second geared motor and a driven gear ring. The second geared motor is fixedly installed on the conveying pipe, and a drive gear is fixedly installed on the output end of the second geared motor. A driven gear ring is fixedly installed on the circumferential side of the bend, and the drive gear meshes with the driven gear ring.

[0014] Furthermore, the conveying pipeline is fixedly installed with a protective box, the second reduction motor, the drive gear and the driven gear ring are located inside the protective box, and the bottom of the protective box is provided with a through hole for the bend to pass through.

[0015] Compared with the prior art, the beneficial effects of this utility model are: Comprehensive and accurate sampling: Through the setting of multiple power mechanisms, extraction tubes, and samplers, raw material samples can be extracted from the storage tank at multiple points. By swinging the bend tube through the swing mechanism, the samples can be discharged into the sampling bucket for storage. This avoids the problem of poor representativeness caused by extracting samples only from the bottom discharge valve, and ensures that the extracted samples can accurately reflect the quality status of the entire batch of raw materials, providing a strong guarantee for the production of high-quality biodegradable membranes.

[0016] The extraction process is smooth and efficient: the power mechanism enables the sampler to rotate and vibrate slightly axially, further preventing raw material jamming and passively adapting to jamming conditions, thus improving the smoothness and adaptability of the extraction.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 This utility model provides a technical solution: an extractor for the production of biodegradable membranes, including a storage tank 1 and a support frame 2 fixedly installed together. The storage tank 1 is located on the lower side of the support frame 2 and plays a supporting role. The storage tank 1 is an existing device with a discharge valve, a tank hopper and a feed inlet, used to store biodegradable membrane raw materials.

[0021] A conveying pipe 5 is fixedly installed on the same side of the storage tank 1 and the support frame 2 by means of a clamp connection. The conveying pipe 5 is set vertically. An extraction pipe 7 is fixedly installed on the storage tank 1. The extraction pipe 7 is set horizontally. One end of the extraction pipe 7 extends into the storage tank 1, and the other end is connected to the conveying pipe 5. A sampler 8 is installed inside the extraction pipe 7. The extraction pipe 7 provides an installation base for the sampler 8 and can connect the storage tank 1 and the conveying pipe 5.

[0022] The conveying pipe 5 is equipped with a power mechanism 6 for driving the sampler 8. The power mechanism 6 is capable of rotating and axially vibrating the sampler 8. A bend 3 is rotatably installed at the lower end of the conveying pipe 5. The conveying pipe 5 is equipped with a swing mechanism 4 for rotating the bend 3. The swing mechanism 4 is capable of swinging the bend 3 and changing the output direction of the conveying pipe 5.

[0023] The extraction tubes 7 consist of 2 to 3 tubes evenly distributed along the axial direction of the conveying pipe 5, depending on the number of sampling points required.

[0024] Please see Figure 2 The structure of sampler 8 is as follows: The sampler 8 includes a rotating rod 81 and a spiral blade 82. The spiral blade 82 is fixedly installed on the circumferential side of the rotating rod 81. One end of the rotating rod 81 passes through the conveying pipe 5 and is used to connect and assemble with the power mechanism 6. The other end of the rotating rod 81 passes through the extraction pipe 7 and extends into the storage tank 1. This end is used to extend the setting length of the spiral blade 82. After the rotating rod 81 rotates in the forward direction, it can extract the raw material in the storage tank 1 into the conveying pipe 5 through the extraction pipe 7.

[0025] The diameter of the portion of the spiral blade 82 that extends into the storage tank 1 gradually decreases as it moves away from the extraction tube 7. This conical portion of the spiral blade 82 reduces the likelihood of the raw material getting stuck between the port of the extraction tube 7 and the spiral blade 82 when it enters the extraction tube 7, making the process of the raw material entering the extraction tube 7 smoother.

[0026] A wear-resistant layer 83 is fixedly installed on the inner circumference of the extraction tube 7. The edge of the spiral blade 82 abuts against the wear-resistant layer 83. The material of the wear-resistant layer 83 can be polyethylene, which has good lubricity and avoids the decline in conveying performance caused by the wear of the edge of the spiral blade 82.

[0027] The structure of the power mechanism 6 is as follows: The power mechanism 6 includes a first geared motor 61 and a linear bearing 64. The linear bearing 64 is fixedly installed on the side of the conveying pipe 5 away from the extraction pipe 7. The linear bearing 64 is horizontally set, and the rotating rod 81 is slidably installed in the linear bearing 64. The setting of the linear bearing 64 allows the rotating rod 81 to rotate or move axially. The first geared motor 61 is fixedly installed on the side wall of the storage tank 1 through a support platform. The output end of the first geared motor 61 is connected and assembled with the rotating rod 81 through a coupling 62. The first geared motor 61 can rotate the rotating rod 81 in the forward and reverse directions through the coupling 62.

[0028] The coupling 62 can be a diaphragm coupling or a bellows coupling, and has the ability to axially displace. The axial displacement distance between the two half-cylinders in the coupling 62 is H, and the value of H is 1 mm to 3 mm.

[0029] A support ring 63 is fixedly installed on the circumferential side of the right half-coupling in the coupling 62. The end face of the support ring 63 near the linear bearing 64 has a wave track. A guide wheel 65 is rotatably installed on the upper side of the support platform. The guide wheel 65 abuts against the wave track. The support ring 63 will rotate with the coupling 62, so that the guide wheel 65 travels along the wave track, and the undulation distance generated by the wave track is 0.6 times H.

[0030] On the one hand, the guide wheel 65 actively creates a slight axial vibration that can be transmitted to the sampler 8, further preventing the raw material from getting stuck between the extraction tube 7 port and the spiral blade 82.

[0031] On the other hand, if raw material gets stuck between the extraction tube 7 port and the spiral plate 82, the sampler 8 can also be passively adjusted axially, making it highly adaptable.

[0032] Please see Figure 3 The structure of the swing mechanism 4 is as follows: The swing mechanism 4 includes a second reduction motor 41 and a driven gear ring 44. The second reduction motor 41 is fixedly installed on the conveying pipe 5. The second reduction motor 41 is vertically arranged. A drive gear 43 is fixedly installed on the output end of the second reduction motor 41. A driven gear ring 44 is fixedly installed on the circumferential side of the bend 3. The drive gear 43 meshes with the driven gear ring 44. The diameter of the drive gear 43 is smaller than that of the driven gear ring 44, which serves to reduce speed and increase torque.

[0033] The second geared motor 41 is a servo motor with an encoder. When working, it can accurately control the number of rotations of the drive gear 43. After being driven by the meshing driven gear ring 44, it can also accurately control the swing angle of the bent tube 3. The number of swing positions is the same as the number of extraction tubes 7, so that one extraction operation corresponds to one swing position.

[0034] In addition, a protective box 42 is fixedly installed on the conveying pipe 5. The second reduction motor 41, the drive gear 43 and the driven gear ring 44 are located inside the protective box 42, and a through hole for the bend 3 to pass through is opened at the bottom of the protective box 42. The protective box 42 plays the role of isolating and protecting the internal components.

[0035] The working principle of this embodiment: The first geared motor 61 and the second geared motor 41, and other electrical components are electrically connected to an external control box. The control box is an existing electrical component with a controller, relays, and buttons, used for unified control and coordinated operation.

[0036] When extracting samples, first place the corresponding number of sampling buckets below the bend 3. The uppermost power mechanism 6 works first, driving the sampler 8 to rotate in the forward direction. At the same time, the sampler 8 will also vibrate, extracting the upper raw material sample from the storage tank 1 into the conveying pipe 5, and then into one of the sampling buckets through the bend 3 for storage. The bent tube 3 is swung towards the next sampling bucket by the swing mechanism 4. At this time, the next power mechanism 6 works to extract the second raw material sample into the corresponding sampling bucket for storage. This process is repeated to complete the extraction operation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
