Description

Technical Field

[0001] The utility model relates to the technical field of compatibilizer processing, in particular to a negative pressure extraction device for cleaning odor in an inner cavity of a compatibilizer extruder. Background Art

[0002] Compatibilizer, also known as macromolecular coupling agent or volume extender, refers to an auxiliary agent that uses the intermolecular bonding force to promote the combination of two incompatible polymers to obtain a stable blend. Its working principle is mainly based on the intermolecular bonding force to help form a stable blend. There are many types of compatibilizers, such as non-reactive copolymers and reactive copolymers. Therefore, the ingredients of the compatibilizer will vary according to these different types of compatibilizers. Generally speaking, the ingredients of the compatibilizer may include some basic polymer materials, which have undergone specific chemical treatment or modification to provide the required compatibility. In addition, some auxiliary ingredients may need to be added, such as catalysts, stabilizers, antioxidants, etc., to optimize the performance of the compatibilizer or extend its service life. The various materials of the compatibilizer need to be evenly mixed and then flow into the storage box for storage. The mixed raw materials in the storage box then flow evenly into the extruder for processing according to demand.

[0003] With respect to the above-mentioned related technologies, the inventors found that when the raw materials enter the extruder for hot melting, an odor is generated. The odor contains small molecule raw materials, which has a great impact on the purity of the product and reduces the quality of the product. Moreover, when the product is formed and discharged, the odor will drift into the air, causing great harm to the human body. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a negative pressure extraction device based on cleaning the odor in the inner cavity of a compatibilizer extruder, thereby improving the purity of the product, enhancing the quality of the product, reducing the odor from drifting into the air, and reducing the harm to the human body.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a negative pressure extraction device based on cleaning the odor in the inner cavity of a compatibilizer extruder, comprising: a workbench, to which an extruder body is connected, a notch is provided on the top of the extruder body, and an odor extraction mechanism is connected to the notch.

[0006] By adopting the above technical solution, when in use, the raw materials of the compatibilizer enter the extruder body, are heated and spirally extruded to form, and an odor is generated during the heating of the raw materials. The odor contains small molecule raw materials, which affect the purity of the product. When the raw materials in the extruder body pass through the notch, the odor extraction mechanism absorbs the odor, thereby improving the purity of the product.

[0007] In a preferred example, the utility model can be further configured as follows: the extruder body includes an extrusion barrel and a spiral extrusion rod disposed in the inner cavity thereof, and the spiral extrusion rod is provided with a clearance groove;

[0008] The odor extraction mechanism comprises a negative pressure box body connected at the notch, an odor guide rod assembly which can extend into the give way groove is installed on the top of the negative pressure box body, and a negative pressure deodorization assembly is connected to one side of the negative pressure box body.

[0009] By adopting the above technical scheme, during use, the spiral extrusion rod spirally extrudes the raw material to move, and under the action of the odor guide rod assembly, the odor in the heated raw material flows out from the groove, and the negative pressure deodorization assembly works so that the inner cavity of the negative pressure box is in a negative pressure state, and the negative pressure box quickly absorbs the gas containing the odor, and the negative pressure deodorization assembly processes the gas containing the odor, and the processed gas is released into the external environment, thereby reducing the odor from drifting into the air and reducing the harm to the human body.

[0011] By adopting the above technical solution, when in use, the telescopic rod of the electric push rod extends and retracts, driving the guide rod to move up and down in the heated raw materials, making it easier for the odor in the raw materials to flow to the groove, thereby enhancing the effect of removing the odor.

[0012] In a preferred example, the utility model can be further configured as follows: the guide rod member includes a guide sleeve and a guide rod body arranged in its inner cavity, the guide sleeve is embedded in the surface of the negative pressure box body, and the lower end outer circle of the guide rod body is spaced apart with at least one movable ring.

[0013] By adopting the above technical solution, the guiding rod drives the moving ring to move in the raw material. During the movement of the moving ring, a channel for odor dissipation is formed in the raw material, thereby enhancing the efficiency of odor dissipation. The moving ring does not interfere with the spiral extrusion rod when moving.

[0014] In a preferred example, the utility model can be further configured as follows: the negative pressure deodorization component includes an air outlet pipe, a duct exhaust fan and a deodorization box, one end of the air outlet pipe is connected to the negative pressure box body, and the other end is connected to the air inlet of the duct exhaust fan, and the air outlet of the duct exhaust fan is connected to the deodorization box by a pipe.

[0015] By adopting the above technical scheme, the duct exhaust fan extracts the gas in the negative pressure box, so that the inner cavity of the negative pressure box is in a negative pressure state, and the negative pressure box absorbs the gas containing the odor. The duct exhaust fan transports the gas containing the odor to the deodorization box, and the deodorization box absorbs the odor.

[0016] In a preferred example, the utility model can be further configured as follows: the deodorizing box comprises a deodorizing box body and activated carbon contained in its inner cavity, an exhaust pipe is connected to a lower end of one side of the deodorizing box body, and an outer end of the exhaust pipe extends to the external environment.

[0017] By adopting the above technical solution, the gas enters the deodorizing box, and due to the presence of activated carbon, the odor in the gas is absorbed and removed, and the odor-free gas is emitted into the external environment through the outlet pipe and the exhaust pipe.

[0018] In a preferred example, the utility model can be further configured as follows: the spiral extrusion rod comprises a rotating shaft, a spiral blade 1 and a spiral blade 2 which are sleeved and connected to its outer circle, the said give way groove is provided between the spiral blade 1 and the spiral blade 2, the outer circles at both ends of the rotating shaft are rotatably connected with a hollow type fixing seat and an end mounting seat respectively, the hollow type fixing seat is connected to the inner wall of the extrusion cylinder, the end mounting seat is connected to the end of the extrusion cylinder, the workbench is connected with a mounting plate, and the mounting plate is connected with a driving motor for driving the rotating shaft to rotate.

[0019] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade 1 and the spiral blade 2 to rotate, so that the raw material is spirally extruded and moved toward the forming port.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. Since the moving ring 523 on the odor guiding rod assembly moves up and down in the raw material, a channel for odor dispersal is formed in the raw material, thereby enhancing the efficiency of odor dispersal.
