Description

Technical Field

[0001] The present application relates to the technical field of powder processing, and in particular to a gas-material separator for conveying powder under negative pressure. Background Art

[0002] The raw materials used for industrial plastic molding mainly include powders, granules, solutions and dispersions. Some molding uses monomers and prepolymers. Powders and granules are more widely used. Powders are made by mixing and dispersing powdered raw resins and various additives. In the process of processing powders, it is necessary to separate the powders from the gas. When separating the powders from the gas, an air-material separator is required.

[0003] At present, the relevant gas-material separators do not have a pre-processing humidity detection and alarm structure, and are unable to detect the humidity inside the device before processing. When the device is not used for a long time, more moisture may enter the interior. If the powder is directly introduced into the processing, it may affect the processing effect of the powder. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a gas-material separator for conveying powder materials under negative pressure.

[0005] The present application provides a gas-material separator for conveying powder materials under negative pressure, which adopts the following technical solution:

[0007] The powder is introduced into the separation tank through the feed pipe, and the gas contained in the device and the powder is extracted by using external exhaust equipment, so that the inside of the device is in a vacuum negative pressure state, and then the discharge valve is opened to allow the powder to pass through the device to other powder processing equipment. The humidity inside the separation tank is detected by the humidity detector. When it is detected that the humidity value inside the separation tank reaches an abnormal value, the controller does not control the butterfly valve to open, and the control prompter sends a prompt voice to remind the staff.

[0008] Preferably, a positioning ring is fixedly connected to the periphery of the separation tank at the bottom of the shell, and a positioning bolt is movably installed inside the positioning ring.

[0009] The separation tank can be disassembled by unscrewing the positioning bolt and lifting the upper part of the shell to separate the two positioning rings, and the two positioning rings are fixed by the positioning bolt.

[0010] Preferably, a protective door is movably mounted on the surface of the shell, and a handle is fixedly connected to the surface of the protective door.

[0011] By holding the handle and pulling open the protective door, you can make relevant settings on the controller.

[0012] Preferably, bolts are movably installed between the indicator and the housing, and four bolts are provided.

[0013] The indicator is fixed to the housing by bolts, and the indicator can be disassembled for maintenance by unscrewing the bolts.

[0017] When the humidity detector detects that the humidity value inside the separation tank reaches an abnormal value, the controller does not control the butterfly valve to open, and controls the prompter to issue a prompt voice to remind the staff that the humidity inside the device is abnormal. After the staff learns that the humidity inside the device is abnormal, they will perform corresponding dehumidification treatment to avoid direct introduction of powder when the inside of the device is relatively humid, which will affect the powder processing effect.

[0025] The staff connects the external material guiding structure with the feed pipe 1, connects the external air extraction device with the air guide pipe 10, and introduces the powder into the interior of the separation tank 6 through the feed pipe 1. The gas contained in the device and the powder is extracted by using the external air extraction device, so that the interior of the device is in a vacuum negative pressure state, and then the discharge valve 7 is opened to allow the powder to be sent to other powder processing equipment through the device. The staff can set the humidity abnormality value through the controller 5. When the staff starts the device, the humidity inside the separation tank 6 is detected by the probe of the humidity detector 3 provided inside the separation tank 6. When it is detected that the humidity value inside the separation tank 6 reaches the abnormal value, the controller 5 does not control the butterfly valve 2 to open, and controls the prompter 9 to issue a prompt voice to remind the staff that the humidity inside the device is abnormal. The staff learns that the humidity inside the device is abnormal Then, it is subjected to corresponding dehumidification treatment to avoid direct introduction of powder when the inside of the device is relatively humid, which would affect the processing effect of the powder. When the humidity data is detected to be a normal value, the butterfly valve 2 is controlled to open by the controller 5 to allow the powder to enter the inside of the device for processing. The moisture-proof shell 11 is made of PVC waterproof and moisture-proof material, which can reduce the possibility of moisture entering the inside of the device. The model of this temperature and humidity detector 3 is RS485, the model of this prompter 9 is WT-E00, the model of this discharge valve 7 is VT2BDF33A, and the model of this butterfly valve 2 is D671X-16. The butterfly valve 2 is a valve that rotates around the valve shaft to achieve opening and closing. The butterfly valve 2, humidity detector 3, prompter 9, controller 5 and discharge valve 7 are all existing technologies and are widely used in society, so they will not be described in detail.

[0026] Reference Figure 1The separation tank 6 at the bottom of the shell 4 is fixedly connected to a positioning ring 8 on its periphery, and a positioning bolt 12 is movably installed inside the positioning ring 8. The positioning bolt 12 is a common bolt body used to fix the positioning ring 8.

[0030] The implementation principle of a gas-material separator for negative pressure conveying of powder in an embodiment of the present application is as follows: the powder is introduced into the interior of a separation tank 6 through a feed pipe 1, and the gas contained in the device and the powder is extracted by utilizing an external vacuum device to achieve gas-material separation, and the humidity inside the separation tank 6 is detected by a humidity detector 3. When it is detected that the humidity value inside the separation tank 6 reaches an abnormal value, the controller 5 does not control the butterfly valve 2 to open, and controls the prompter 9 to issue a prompt voice to remind the staff. When it is detected that the humidity data is a normal value, the controller 5 controls the butterfly valve 2 to open, so that the powder enters the interior of the device for processing.
