Description

Technical Field

[0001] The invention relates to a device and a method for simultaneously detecting the material level and liquid level of an extractor, belonging to the technical field of plant extraction methods. Background Art

[0002] In the field of plant extraction, the rotary extractor is a highly efficient device in the extraction process and is widely used. However, due to the particularity of the equipment, the rotary rotation speed and solvent immersion effect in the rotating immersion grid have always been based on experience. There are many interference factors in the production process, which will directly affect the production efficiency of the rotary extractor and the yield of the extracted product. Therefore, how to control the material level and the liquid level of the solvent immersion liquid in each material grid is an urgent problem that needs to be solved. The key to solving this problem is to try to measure the material level and the liquid level at the same time.

[0003] Patent Publication No. CN202122280805.4 employs a monitoring marker fixed to the partition of a horizontally rotating extractor, and uses camera images to analyze whether the material and liquid levels are within normal positions. This method is only suitable for situations where the material does not fluctuate significantly, but it cannot accurately measure the material and liquid levels, and the automatic control system cannot accurately adjust the feed rate and solvent replenishment. Patent Publication No. CN201410312655.2 provides a dual-level measurement device for measuring liquid and material levels. This device can only be used in fixed containers and is not suitable for continuously rotating horizontally rotating extractors.

[0004] The existing device that can simultaneously measure the material level and the liquid level cannot be used normally in the rotating flat-rotating extractor. It is necessary to design a device that can simultaneously and reliably measure the material level and the liquid level in an environment where the flat-rotating extractor is constantly rotating. Summary of the Invention

[0005] The purpose of the present invention is to provide a device and method for simultaneously detecting the material level and liquid level of an extractor. Through the application of angle sensors, pause metering contacts and start metering contacts, uninterrupted and accurate measurement of the material level and liquid level can be completed during the horizontal rotation process of the extractor. The structure is simple and reliable, suitable for continuous industrial production, and effectively solves the above-mentioned problems existing in the background technology.

[0006] The technical solution of the present invention is: a device for simultaneously detecting the material level and liquid level of an extractor, comprising angle sensor 1, angle sensor 2, a liquid level measuring ball, a material level measuring ball, a pause metering contact, a start metering contact and a translation partition, wherein the angle sensor 1 and the angle sensor 2 are located on the same horizontal line in the same vertical plane; the angle sensor 1 and the angle sensor 2 are respectively connected to the liquid level measuring ball and the material level measuring ball through a connecting rod; the pause metering contact is arranged below the angle sensor 1 and the angle sensor 2, and its height matches the translation partition; the start metering contact is arranged at the position where the liquid level measuring ball and the material level measuring ball separate from the translation partition during the rotation process.

[0007] The angle sensor 1, the angle sensor 2, the liquid level measuring ball, the material level measuring ball, the pause metering contact and the start metering contact constitute a measuring device. There are two groups of measuring devices. The installation distance of the two groups of measuring devices matches the distance between the pause metering contacts and the start metering contacts of the same group of measuring devices, and the start metering contacts of the latter group of measuring devices are triggered earlier than the pause metering contacts of the former group of measuring devices.

[0008] The density of the liquid level measuring ball is smaller than that of the solvent used, and the density of the material level measuring ball is larger than that of the solvent used.

[0009] The connecting rods connecting the angle sensor 1 and the angle sensor 2 with the liquid level measuring ball and the material level measuring ball are hard rods, and a triangular plate is fixed at the position where the liquid level measuring ball and the material level measuring ball are connected to the connecting rods.

[0010] The height of the metering pause contact is slightly higher than that of the horizontally rotating partition.

[0011] A method for simultaneously detecting the material level and liquid level of an extractor comprises the following steps:

[0012] (1) Angle sensor 1, angle sensor 2, liquid level measuring ball, material level measuring ball, pause metering contact and start metering contact constitute the measuring device. Angle sensor 1 and angle sensor 2 are installed on the same horizontal line in the same vertical plane. Angle sensor 1 and angle sensor 2 are connected to the liquid level measuring ball and material level measuring ball respectively through connecting rods. The horizontal rotating partition will contact with the connecting rod and interfere with the measurement during the rotation process. The pause metering contact is installed at the same height as the horizontal rotating partition below angle sensor 1 and angle sensor 2. The start metering contact is installed at the position where the measuring ball is separated from the horizontal rotating partition. The measurement is completed by relaying two sets of measuring devices with appropriate distances;

[0013] (2) During production, the horizontal rotating extractor starts to rotate, and the horizontal rotating partition first triggers the start metering contact of the first set of measuring devices. The first set of measuring devices starts measuring, and the liquid level measuring ball floats above the liquid surface and drives the angle sensor 1 to rotate a certain angle through the connecting rod. The angle sensor 1 transmits the angle signal to the computer, and the computer calculates the liquid level height according to the preset parameters; the material level measuring ball is at the interface between the material and the solvent and drives the angle sensor 2 to rotate a certain angle through the connecting rod. The angle sensor 2 transmits the angle signal to the computer, and the computer calculates the material height according to the preset parameters;

[0014] (3) The horizontal rotating extractor continues to rotate. When the horizontal rotating partition triggers the start metering contact of the second set of measuring devices, the second set of measuring devices starts measuring. The computer preferentially uses the signals of the second set of measuring devices to calculate the liquid level and material level. Through this relay method, the liquid level and material level are continuously detected.

[0015] (4) The horizontal rotating extractor continues to rotate. When the horizontal rotating partition triggers the pause metering contact of the first group of measuring devices, the first group of measuring devices suspends measurement to prevent the computer from outputting incorrect liquid level and material level.

[0016] In the step (1), the installation distance between the two groups of measuring devices matches the distance between the pause metering contacts and the start metering contacts of the same group of measuring devices, and satisfies the requirement that the start metering contacts of the latter group of measuring devices are triggered earlier than the pause metering contacts of the former group of measuring devices.

[0017] In the step (1), the installation distance between the two groups of measuring devices matches the distance between the pause metering contact and the start metering contact of the same group of measuring devices, and the pause metering contact of the first group of measuring devices is used as the start metering contact of the second group of measuring devices.

[0018] The density of the liquid level measuring ball is smaller than that of the solvent used, and the density of the material level measuring ball is larger than that of the solvent used.

[0019] The connecting rods connecting the angle sensor 1 and the angle sensor 2 with the liquid level measuring ball and the material level measuring ball are hard rods, and a triangular plate is fixed at the position where the liquid level measuring ball and the material level measuring ball are connected to the connecting rods.

[0020] The beneficial effects of the present invention are: through the application of angle sensors, pause metering contacts and start metering contacts, uninterrupted and accurate measurement of material level and liquid level can be completed during the horizontal leaching rotation process; the structure is simple and reliable, and is suitable for continuous industrial production.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the invention implementation cases clearer, the technical solutions in the invention implementation cases will be clearly and completely described below in conjunction with the drawings in the implementation cases. Obviously, the implementation cases described are only a small part of the implementation cases of the present invention, rather than all the implementation cases. Based on the implementation cases in the present invention, all other implementation cases obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] A device for simultaneously detecting the material level and liquid level of an extractor, comprising an angle sensor 1, an angle sensor 2, a liquid level measuring ball 3, a material level measuring ball 4, a pause metering contact 5, a start metering contact 6 and a horizontally rotating partition 7. The angle sensor 1 and the angle sensor 2 are located on the same horizontal line in the same vertical plane; the angle sensor 1 and the angle sensor 2 are respectively connected to the liquid level measuring ball 3 and the material level measuring ball 4 through a connecting rod; the pause metering contact 5 is arranged below the angle sensor 1 and the angle sensor 2, and its height matches the horizontally rotating partition 7; the start metering contact 6 is arranged at a position where the liquid level measuring ball 3 and the material level measuring ball 4 are separated from the horizontally rotating partition 7 during the rotation process.

[0026] The angle sensor 1, angle sensor 2, liquid level measuring ball 3, material level measuring ball 4, pause metering contact 5 and start metering contact 6 constitute a measuring device. There are two groups of measuring devices. The installation distance of the two groups of measuring devices matches the distance between the pause metering contact 5 and the start metering contact 6 of the same group of measuring devices, and it satisfies that the start metering contact 6 of the latter group of measuring devices is triggered earlier than the pause metering contact 5 of the former group of measuring devices.

[0027] The liquid level measuring ball 3 has a lower density than the solvent used, and the material level measuring ball 4 has a higher density than the solvent used.

[0028] The connecting rods connecting the angle sensor 1 1 and the angle sensor 2 2 with the liquid level measuring ball 3 and the material level measuring ball 4 are hard rods, and a triangular plate is fixed at the position where the liquid level measuring ball 3 and the material level measuring ball 4 are connected to the connecting rods.

[0029] The height of the metering pause contact 5 is slightly higher than the horizontal rotating partition 7.

[0030] A method for simultaneously detecting the material level and liquid level of an extractor comprises the following steps:

[0031] (1) Angle sensor 1, angle sensor 2, liquid level measuring ball, material level measuring ball, pause metering contact and start metering contact constitute the measuring device. Angle sensor 1 and angle sensor 2 are installed on the same horizontal line in the same vertical plane. Angle sensor 1 and angle sensor 2 are connected to the liquid level measuring ball and material level measuring ball respectively through connecting rods. The horizontal rotating partition will contact with the connecting rod and interfere with the measurement during the rotation process. The pause metering contact is installed at the same height as the horizontal rotating partition below angle sensor 1 and angle sensor 2. The start metering contact is installed at the position where the measuring ball is separated from the horizontal rotating partition. The measurement is completed by relaying two sets of measuring devices with appropriate distances;

[0032] (2) During production, the horizontal rotating extractor starts to rotate, and the horizontal rotating partition first triggers the start metering contact of the first set of measuring devices. The first set of measuring devices starts measuring, and the liquid level measuring ball floats above the liquid surface and drives the angle sensor 1 to rotate a certain angle through the connecting rod. The angle sensor 1 transmits the angle signal to the computer, and the computer calculates the liquid level height according to the preset parameters; the material level measuring ball is at the interface between the material and the solvent and drives the angle sensor 2 to rotate a certain angle through the connecting rod. The angle sensor 2 transmits the angle signal to the computer, and the computer calculates the material height according to the preset parameters;

[0033] (3) The horizontal rotating extractor continues to rotate. When the horizontal rotating partition triggers the start metering contact of the second set of measuring devices, the second set of measuring devices starts measuring. The computer preferentially uses the signals of the second set of measuring devices to calculate the liquid level and material level. Through this relay method, the liquid level and material level are continuously detected.

[0034] (4) The horizontal rotating extractor continues to rotate. When the horizontal rotating partition triggers the pause metering contact of the first group of measuring devices, the first group of measuring devices suspends measurement to prevent the computer from outputting incorrect liquid level and material level.

[0035] In the step (1), the installation distance between the two groups of measuring devices matches the distance between the pause metering contacts and the start metering contacts of the same group of measuring devices, and satisfies the requirement that the start metering contacts of the latter group of measuring devices are triggered earlier than the pause metering contacts of the former group of measuring devices.

[0036] In the step (1), the installation distance between the two groups of measuring devices matches the distance between the pause metering contact and the start metering contact of the same group of measuring devices, and the pause metering contact of the first group of measuring devices is used as the start metering contact of the second group of measuring devices.

[0037] The density of the liquid level measuring ball is smaller than that of the solvent used, and the density of the material level measuring ball is larger than that of the solvent used.

[0038] The connecting rods connecting the angle sensor 1 and the angle sensor 2 with the liquid level measuring ball and the material level measuring ball are hard rods, and a triangular plate is fixed at the position where the liquid level measuring ball and the material level measuring ball are connected to the connecting rods.

[0039] In actual application, angle sensor 1 and angle sensor 2 2 on the same horizontal line in the same vertical plane are respectively connected to the liquid level measuring ball 3 and the material level measuring ball 4 through a connecting rod. The density of the liquid level measuring ball 3 is smaller than that of the solvent used, and the density of the material level measuring ball 4 is larger than that of the solvent used. During the rotation of the horizontal extractor, the liquid level measuring ball 3 and the material level measuring ball 4 drive the angle sensor 1 and the angle sensor 2 2 to rotate a certain angle. The angle signal is converted into the height of the liquid level measuring ball 3 and the material level measuring ball 4 by the computer according to preset parameters, so as to measure the material level and the liquid level. The horizontal partition 7 will contact with the connecting rod during the rotation process and interfere with the measurement. A pause metering contact 5 is installed at the same height as the horizontal partition 7 below the angle sensor 1 and the angle sensor 2, and a start metering contact 6 is installed at the position where the liquid level measuring ball 3 and the material level measuring ball 4 are separated from the horizontal partition. The measurement is completed by relaying two sets of measuring devices with appropriate distances.

[0040] The liquid level measuring ball 3 and the material level measuring ball 4 are connected to the angle sensor 1 and the angle sensor 2 by hard rods, and a triangular plate is fixed at the connection position between the measuring ball and the rod so that the liquid level measuring ball 3 and the material level measuring ball 4 can slide smoothly when they come into contact with the horizontal rotating partition 7.

[0041] The height of the pause metering contact 5 is slightly higher than the horizontal rotating partition 7, so that when the horizontal rotating partition 7 rotates to the position of the pause metering contact 5, it can pass through and trigger the contact point. The pause contact point 5 sends a signal to the computer to pause this group of measuring devices and enable the next group of measuring devices.

[0042] The start metering contact 6 is in the position where the liquid level measuring ball 3 and the material level measuring ball 4 are separated from the horizontal rotating partition 7 during the rotation process. When the horizontal rotating partition 7 separates from the liquid level measuring ball 3 and the material level measuring ball 4, the start metering contact 6 is triggered to enable this group of measuring devices.

[0043] The distance between each group of measuring devices needs to satisfy the requirement that the start metering contact 6 of the latter group is triggered earlier than the pause metering contact 5 of the former group of measuring devices, and the computer gives priority to using the signal of the newly triggered measuring device.

[0044] Example:

[0045] 1. During production, the horizontally rotating extractor starts to rotate, and the horizontally rotating partition 7 first triggers the start metering contact 6 of the first group of measuring devices. The first group of metering devices starts measuring, and the liquid level measuring ball 3 floats above the liquid surface and drives the angle sensor 1 to rotate a certain angle through the connecting rod. The angle sensor 1 transmits the angle signal to the computer, and the computer calculates the liquid level height according to the preset parameters; the material level measuring ball 4 is at the interface between the material and the solvent and drives the angle sensor 2 to rotate a certain angle through the connecting rod. The angle sensor 2 transmits the angle signal to the computer, and the computer calculates the material height according to the preset parameters.

[0046] 2. The horizontally rotating extractor continues to rotate. When the horizontally rotating partition 7 triggers the start metering contact 6 of the second group of measuring devices, the second group of measuring devices starts measuring. The computer preferentially uses the signals of the second group of measuring devices to calculate the liquid level and material level. The liquid level and material level are continuously detected through this relay method.

[0047] 3. The horizontal rotating extractor continues to rotate. When the horizontal rotating partition 7 triggers the pause metering contact 5 of the first group of measuring devices, the first group of measuring devices suspends measurement to prevent the computer from outputting incorrect liquid level and material level.

[0048] 4. Preferably, when the application environment is ideal, the first group of pause metering contacts 6 can be used as the second group of start metering contacts 5 to reduce parts and calculations.
