Description

TECHNICAL FIELD

[0001] The present application relates to the field of material collection, in particular to a high-efficiency full-automatic material collection device. BACKGROUND

[0002] In the production of traditional Chinese medicine or other powders, a cyclone separator is needed. The existing cyclone separator usually uses cyclone to produce centrifugal force in the separator, which drives the powder to the inner wall under the action of centrifugal force. After the powder collides with the inner wall, the powder settles downward under the action of gravity, and the gas is discharged through the upper gas pipe. This separator mainly separates the mixed powder of powder and gas, and collects the powder alone. However, the existing separator uses a single valve, so that when collecting material, the bottom discharge port is opened, and the powder is continuously input into the separator under the action of wind. After the single valve is opened, the pipeline between the separator and the material collection cage cannot be closed, so that the powder is easily directly input into the material collection cage through the pipeline under the action of wind, and the powder in the cage is blown up, so that the stored powder in the material collection cage is blown into the separator again, causing the powder to run off and waste. Therefore, the existing mechanism needs to temporarily stop the powder conveying during collection to avoid the situation that the single valve cannot block the powder directly input into the material collection cage under the action of wind, thereby reducing the work efficiency. Therefore, measures need to be provided to solve the problem that after the existing separator uses a single valve, the powder is easily directly input into the material collection cage through the pipeline under the action of wind, so that the powder in the cage is blown into the separator again, causing the powder to run off and waste. SUMMARY

[0003] The purpose of the present application is to overcome the defects of the prior art, provide a high-efficiency full-automatic material collection device, and solve the problem that after the existing separator uses a single valve, the powder is easily directly input into the material collection cage through the pipeline under the action of wind, so that the powder in the cage is blown into the separator again, causing the powder to run off and waste.

[0004] The technical scheme for achieving the above-mentioned purpose is: a high-efficiency full-automatic material collection device, comprising:

[0005] a separator for separating the powder and gas in the input mixture;

[0006] a material conveying pipe connected below the separator, the material conveying pipe being vertically arranged;

[0007] a first valve connected to the material conveying pipe;

[0008] a second valve connected to the material conveying pipe below the first valve;

[0009] A PLC controller is connected to the first valve and the second valve, and the first valve and the second valve are controlled by the PLC controller to be opened and closed alternately, when the first valve is opened, the second valve is closed, so that the powder in the conveying pipe falls down to the first valve and the second valve, when the second valve is opened, the first valve is closed, so that the powder falls down to the bottom of the conveying pipe, and a collecting cage is connected to the bottom of the conveying pipe to collect the powder falling in the conveying pipe.

[0010] The technical scheme of the present application is further improved in that the separating mechanism comprises a barrel body, a feeding port connected to the barrel body, an air outlet connected to the top of the barrel body, and a hopper connected to the bottom of the barrel body, and the hopper is connected to the conveying pipe.

[0011] The technical scheme of the present application is further improved in that a hammering device is connected to the hopper, and the hopper is hit by the hammering device to hit and fall the powder adhered to the inner wall of the hopper.

[0012] The technical scheme of the present application is further improved in that the hammering device is inclined downward.

[0013] The technical scheme of the present application is further improved in that the first valve and the second valve are both pneumatic butterfly valves.

[0014] The technical scheme of the present application is further improved in that the first valve is connected to the conveying pipe and close to one end of the separating mechanism.

[0015] The second valve is connected to the conveying pipe and close to one end of the collecting cage.

[0016] The technical scheme of the present application is further improved in that the first valve and the second valve are perpendicular to the conveying pipe.

[0017] The technical scheme of the present application is further improved in that the pipe opening of the conveying pipe is matched with the separating mechanism and the collecting cage.

[0018] The technical scheme of the present application is further improved in that the separating mechanism is gradually reduced from top to bottom.

[0019] The technical scheme of the present application is further improved in that the collecting cage is gradually expanded from top to bottom.

[0020] By using the above technical scheme, the present application has the following technical effects compared with the prior art:

[0021] This invention provides a high-efficiency fully automatic material collection device. By installing two valves, a first and a second, on the conveying pipe, which alternately open and close, the bottom collection cage is isolated from the upper separation mechanism when one valve is closed and the other open. This prevents the collection cage from connecting with the separation mechanism, avoiding the situation where the separator uses only a single valve, resulting in powder flying out from the bottom when that valve is opened. Simultaneously, by using the two valves to maintain a constant separation between the collection cage and the separation mechanism, powder can be continuously output to the separation mechanism without needing to shut down the conveying system during collection. Therefore, material collection can be performed simultaneously with powder separation, achieving efficient work and significantly improving work efficiency. Furthermore, it prevents outside air from entering the mechanism from the bottom, creating an internal seal. The alternating opening and closing of the two valves also prevents airflow differences at the bottom of the conveying pipe, avoiding accidental powder discharge and reducing powder loss. This achieves efficient and thorough powder collection, reducing costs.

[0022] By installing a hammer on the separation mechanism and setting the hammer to strike the separation mechanism at regular intervals, the powder adhering to the inner wall of the separation mechanism is shaken off and falls back down, thus avoiding waste of powder. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] This invention provides a high-efficiency fully automatic material receiving device. This device utilizes two valves, one open and one closed, to consistently separate the receiving cage from the separation mechanism, preventing cyclones from blowing into the receiving cage from the separation mechanism and affecting the powder inside, thus achieving an internal sealing effect. The high-efficiency fully automatic material receiving device is described below.

[0028] See Figure 1 This image shows a plan view of a high-efficiency fully automatic material receiving device according to the present invention. The following is in conjunction with... Figures 1-2 The structure of the high-efficiency fully automatic material receiving device of the present invention will be described.

[0029] See Figure 1This invention provides a high-efficiency fully automatic material receiving device, comprising: a separation mechanism 1, a conveying pipe 3, a first valve 4, a second valve 5, and a receiving cage 6. The separation mechanism 1 is used to separate powder and gas in the input mixed material. The separation mechanism 1 can be connected to a crushing mechanism via a pipeline, and the crushing mechanism can output the mixed powder to the separation mechanism 1 through the pipeline. The powder crushed by the crushing mechanism is continuously blown into the separation mechanism 1 through the pipeline. The separation mechanism 1 separates the powder and gas in the input mixed material. By using a cyclone to blow, the cyclone rotates in the separation mechanism 1, generating centrifugal force, causing the powder to hit the inner wall and slide down to the bottom of the separation mechanism 1. The conveying pipe 3 is connected below the separation mechanism 1 and is vertically arranged. The feed pipe 3 collects the powder collected by the separation mechanism 1. The first valve 4 is connected to the feed pipe 3, and the second valve 5 is connected to the feed pipe 3 and located below the first valve 4. The PLC controller is connected to the first valve 3 and the second valve 4, and controls the first valve 4 and the second valve 5 to open and close alternately. When the first valve 4 is open, the second valve 5 is closed, so that the powder in the feed pipe 3 falls down between the first valve 4 and the second valve 5. When the second valve 5 is open, the first valve 4 is closed, thus achieving alternating opening and closing. When the second valve 5 is open, the powder falls down to the bottom of the feed pipe 3. The collection cage 6 connected to the bottom of the feed pipe 3 collects the powder that falls from the feed pipe 3.

[0030] Better, such as Figure 1 As shown, the crushed powder in the crushing mechanism is fed into the separation mechanism 1 through the pipeline. The centrifugal force generated by the cyclone blows the powder to hit the inner wall and slide down to the bottom of the separation mechanism 1, thereby moving downward along the conveying pipe 3, while the cyclone is discharged from the top of the separation mechanism 1.

[0031] Furthermore, when the first valve 4 is opened, the second valve 5 will be closed. At this time, the powder will fall from the first valve 4 onto the second valve 5, and the seal used in the valve is made of food-grade material to avoid contaminating the powder.

[0032] Furthermore, such as Figure 2As shown, the interval of the opening and closing of the first valve 4 is usually ten seconds, and the powder can fall to the second valve 5 in the interval. The opening and closing interval of the second valve 5 is the same as that of the first valve 4, but the opening and closing time of the valve needs to be adjusted according to the actual production, so that the pipeline of the conveying pipe 3 between the two valves is not full of powder, and the bottom of the separation mechanism 1 is not full of powder. When the valve action model is sent out, if the PLC controller does not receive the switch signal feedback within five seconds, the control system will issue an alarm to prompt the operator to check the valve action, so as to avoid the situation that the valve is not opened and causes internal blocking of the separation mechanism 1. By alternately opening the two valves, the powder is isolated from the outside after entering the separation mechanism 1, so as to achieve the effect of internal sealing. By setting one valve to be opened and the other valve to be closed, the receiving cage 6 can be separated from the space of the separation mechanism 1 at all times, so that the outside air cannot enter the inside of the mechanism from the bottom during the collection of the powder by the receiving cage 6, thereby solving the problem of pollution of the powder by the outside air.

[0033] Referring to Figure 1 In one specific embodiment of the present application, the separation mechanism 1 includes a barrel body, a feed inlet connected to the barrel body, an exhaust port connected to the top of the barrel body, and a hopper connected to the bottom of the barrel body.

[0034] Further, as shown, Figure 1 The powder is put into the feed inlet and falls into the hopper, and the hopper concentrates and outputs the powder downward due to its wide top and narrow bottom.

[0035] Referring to Figure 1 In one specific embodiment of the present application, the hopper is connected with a hammer 2, and the hammer 2 is started to hit the hopper to shake off the powder adhered to the inner wall of the hopper.

[0036] Further, as shown, Figure 1 The PLC controller is arranged on the hammer 2 to control the hammer 2 to hit the hopper at a regular time, so that the powder adhered to the inner wall of the hopper is shaken off, and the powder falls downward again, thereby avoiding waste of the powder.

[0037] Referring to Figure 1 In one specific embodiment of the present application, the hammer 2 is inclined downward.

[0038] Referring to Figure 1 In one specific embodiment of the present application, the first valve 4 and the second valve 5 are both pneumatic butterfly valves.

[0039] Referring to Figure 1In one specific embodiment of the present invention, the first valve 4 is connected to the conveying pipe 3 and is close to one end of the separation mechanism, and the second valve is connected to the conveying pipe 3 and is close to one end of the receiving cage 6.

[0040] Furthermore, such as Figure 1 As shown, by setting the first valve 4 and the second valve at opposite ends of the conveying pipe 3, the two valves isolate a space in the middle of the conveying pipe 3 where powder can be temporarily stored.

[0041] See Figure 1 In one specific embodiment of the present invention, the first valve 4 and the second valve are perpendicular to the conveying pipe.

[0042] See Figure 1 In one specific embodiment of the present invention, the inlet of the conveying pipe 3 is adapted to the separation mechanism 1 and the receiving cage 6.

[0043] Furthermore, such as Figure 1 As shown, by setting the opening of the conveying pipe 3 to a diameter that is compatible with the separation mechanism 1 and the receiving cage 6, the conveying pipe 3 can be fully connected to the separation mechanism 1 and the receiving cage 6.

[0044] See Figure 1 In one specific embodiment of the present invention, the separation mechanism 1 gradually decreases in size from top to bottom.

[0045] Furthermore, such as Figure 1 As shown, the wide-at-the-top and narrow-at-the-bottom design allows the powder to automatically gather together and be centrally fed into the conveying pipe 3.

[0046] See Figure 1 In one specific embodiment of the present invention, the receiving cage 6 gradually expands from top to bottom.

[0047] Furthermore, such as Figures 1-2 As shown, the narrow top and wide bottom design allows the powder to disperse actively after being discharged from the conveying pipe 3, preventing it from piling up and causing blockages.

[0048] like ​ As shown, the installation process of a high-efficiency fully automatic material receiving device of the present invention will be described below.

[0049] First, the broken powder in the crushing mechanism is blown into the separating mechanism 1 through a pipeline, and the powder falls spirally in the separating mechanism 1 by the cyclone generated when being input, and in the falling process, the powder hits the inner wall of the separating mechanism 1 under the action of centrifugal force, and then falls onto the first valve 4 in the material conveying pipe 3, the hammer 2 is used to hammer the separating mechanism 1, so that the powder adhered to the inner wall of the separating mechanism 1 falls downward again, when the first valve 4 is opened, the powder thereon falls onto the second valve 5, when the first valve 4 is closed, the second valve 5 is opened, and at this time, the powder falls into the material collecting cage 6.

[0050] The application is described in detail above in combination with the embodiments of the drawings, and those skilled in the art can make various changes to the application according to the above description. Therefore, some details in the embodiments should not constitute a limitation on the application, and the scope of protection of the application will be defined by the appended claims.
