Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine impurity removal equipment, in particular to a pneumatic separation device for rapid impurity removal in traditional Chinese medicine processing. Background Technique

[0002] Traditional Chinese medicine, as a treasure of the long history and culture of the Chinese nation, is unique not only in its profound cultural heritage, but also in its rigorous collection, processing and preparation processes, all of which are closely based on the wisdom of traditional Chinese medicine theory. The processing of traditional Chinese medicine, as a key link connecting the original form of medicinal materials and clinical application, is not only to remove non-medicinal parts in the medicinal materials, such as residues, debris and dust, but also to enhance the curative effect of the medicine, reduce toxicity and change the properties of the medicine through specific technological means, such as frying, roasting, calcining, steaming, boiling, etc., so as to better meet the clinical needs.

[0003] At present, in order to remove non-medicinal parts in the medicinal materials, such as residues, debris and dust, it is usually necessary for workers to manually screen or use a dustpan to remove the residues, debris or dust in the medicinal materials. This method has a high labor intensity, low efficiency, and poor impurity removal effect on the medicinal materials, affecting the performance of traditional Chinese medicine processing products. Content of the Utility Model

[0004] The utility model aims to provide a pneumatic separation device for rapid impurity removal in traditional Chinese medicine processing to solve the problems of high labor intensity, low efficiency and poor impurity removal effect in the prior art when manually screening or using a dustpan to remove impurities in the medicinal materials.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] The basic technical solution provided by the utility model is: a pneumatic separation device for rapid impurity removal in traditional Chinese medicine processing, including a housing, a support rod is connected to the lower side of the housing, a first discharge port is connected to the side end of the housing, a second discharge port is connected to the lower end of the housing, a pneumatic separation cylinder is communicated with the top end of the housing, a third discharge port is connected to the side end of the pneumatic separation cylinder, an air inlet pipe is connected to the side of the pneumatic separation cylinder far from the third discharge port, a fan is arranged on the air inlet pipe, a feed pipe is connected to the upper end of the pneumatic separation cylinder, and a feed hopper is connected to the upper end of the feed pipe;

[0007] The housing is fixedly connected with a second motor. The output shaft of the second motor is fixedly connected with a connecting rod. The connecting rod is rotatably connected with a screening hopper. The screening hopper is located between the air separation cylinder and the second discharge port. The side opening of the screening hopper is located above the first discharge port. The screening hopper is provided with a strip-shaped groove. The housing is fixedly connected with a sliding rod that is slidably connected with the strip-shaped groove. The housing is provided with an annular groove. The screening hopper is slidably connected with the annular groove. The radius of the annular groove is equal to the length of the connecting rod, and the horizontal height of the lowest point of the annular groove is the same as the horizontal height of the sliding rod. The screening hopper is detachably connected with a sieve mesh.

[0008] Principle of the basic technical solution: Chinese medicinal materials enter the air separation cylinder from the feed hopper through the feed pipeline. The air blower generates wind force, which diffuses into the air separation cylinder through the ventilation pipeline, blowing out some impurities of the Chinese medicinal materials from the third discharge port. The remaining Chinese medicinal materials fall down into the screening hopper. Driven by the second motor, the connecting rod rotates, and the connecting rod controls one end of the screening hopper to move along the annular groove. Through the control of the strip-shaped groove and the sliding rod, the screening hopper swings periodically to achieve the screening effect. The impurities pass through the sieve mesh and fall into the second discharge port, and the screened Chinese medicinal materials fall into the first discharge port through the side opening of the screening hopper.

[0009] The beneficial effects of the basic technical solution are as follows: Chinese medicinal materials are first subjected to air separation for the first impurity removal, so as to remove impurities with lighter weight in the Chinese medicinal materials, such as floating flocs. The screening hopper is driven by the motor to swing cyclically, so as to remove impurities with heavier weight, such as stones. Through the combination of air separation and screening, the impurity removal effect is good and the efficiency is high, which is convenient for use. In addition, through the detachable setting of the sieve mesh, the sieve mesh with a suitable mesh size can be replaced according to the volume of different medicinal materials, thereby improving the adaptability of the device and facilitating the cleaning of the sieve mesh.

[0011] Preferably, the side of the screening hopper close to the first discharge port is inclined downward by 15°, and the side of the first discharge port close to the screening hopper is inclined upward by 30°.

[0012] Through the above settings, the side of the screening hopper close to the first discharge port is inclined downward, which is convenient for the discharge of Chinese herbal medicines.

The side of the screening hopper close to the first discharge port is inclined downward by 15°, and the side of the first discharge port close to the screening hopper is inclined upward by 30°, so that there is a relative sliding angle between the two, making the material guiding and taking more convenient and fast.

[0013] Preferably, the screening hopper is provided with a chute, the screen is slidably connected to the screening hopper through the chute, and the screening hopper is provided with a clamping mechanism for fixing the screen.

A tension spring is connected between the clamping block and the mounting seat, and the clamping block is clamped with the screen.

[0016] With the above arrangement, when the screen needs to be replaced, the clamping block is pulled upward to disengage it from the screen, and then the screen can be taken out.

[0017] Preferably, a maintenance opening is provided at the side end of the housing, and a sliding plate for opening and / or closing the maintenance opening is slidably connected to the housing.

[0018] With the above arrangement, the sliding plate is pushed to expose the maintenance opening, which is convenient for cleaning or replacing the screen.

[0019] Preferably, a slide rail is provided on the housing, the sliding plate is slidably connected to the housing through the slide rail, and a knob for fixing the sliding plate is threadedly connected to the housing.

[0020] With the above arrangement, the stability of the sliding plate is improved by the setting of the slide rail, and the sliding plate is convenient to be fixed by the setting of the knob.

[0021] Preferably, a transmission roller is rotatably connected to the inner side of the feed pipe. A first motor is fixedly connected to the upper end of the air separation cylinder, and the output shaft of the first motor is fixedly connected to the rotating shaft of the transmission roller.

[0022] With the above arrangement, the rotation speed of the transmission roller controls the feeding speed of the Chinese medicinal materials, so that the staff can adjust the rotation speed of the transmission roller adaptively according to different medicinal materials.

[0023] Preferably, the blower is a speed-regulating blower, and both the first motor and the second motor are speed-regulating motors.

[0024] With the above arrangement, according to the density and volume of different medicinal materials, the output power of the blower and / or the motor is adjusted, and the screening and impurity removal effects are good.

[0025] Preferably, the housing is provided with a control module, and the control module is electrically connected to the blower, the first motor and the second motor to control their operations.
