[0002] A filtration device for nylon thermal insulation strip masterbatch production is a specialized piece of equipment used to remove impurities or uneven particles from the raw materials of nylon thermal insulation strips. Filtration ensures the purity or particle size uniformity of the masterbatch after melting. Its necessity lies in the fact that if impurities or particles in the raw materials are not removed, it will lead to problems such as porosity and unstable thermal conductivity in the final formed thermal insulation strip, which directly affects the energy-saving effect and service life of the building's sealing structure. Therefore, it is necessary to ensure the quality of materials from the source through precise filtration to meet the production requirements of high-performance building thermal insulation materials.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A filtration device for producing nylon thermal insulation strip masterbatch includes a first filter cylinder 101, a second filter cylinder 102 bolted to the bottom of the first filter cylinder 101, filter screens 103 fixedly installed inside the first filter cylinder 101 and the second filter cylinder 102, respectively, and discharge outlets 104 are respectively provided on the filter screens 103, with discharge connectors 105 extending from the discharge outlets 104 and respectively penetrating through the outside of the first filter cylinder 101 and the second filter cylinder 102.

[0024] The above scheme achieves modular assembly of multi-stage filtration chambers through the bolted connection structure of the first and second filter cylinders. The filter screen classifies and screens the raw materials, and the extended and continuous design of the discharge outlet and discharge connector directionally discharges particles of different sizes, forming a gradient filtration separation.

[0025] In this embodiment, preferably, a suction cylinder 106 is bolted to the side of the second filter cylinder 102 away from the discharge connector 105, and a suction connector 107 is fixedly installed on the side of the suction cylinder 106 away from the second filter cylinder 102.

[0026] The above scheme establishes a negative pressure airflow channel through the bolted connection between the suction cylinder and the second filter cylinder, and generates stable suction by connecting to an external negative pressure device through the suction connector, thereby accelerating the efficiency of material penetration through the filter screen.

[0027] In this embodiment, preferably, a first motor 108 is bolted to the end of the suction cylinder 106 away from the second filter cylinder 102, and the output end of the first motor 108 is connected to the rotating filter element 109 through a shaft passing through the inside of the second filter cylinder 102.

[0028] The above scheme uses a first motor to drive the rotating filter element to rotate at high speed, generating a centrifugal force field. The rotating filter element separates the adsorbed micro powder material by centrifugation, and the ultrafine particles are removed through an independent discharge channel.

[0029] In this embodiment, preferably, a hopper 110 is bolted to the bottom of the second filter cylinder 102, a valve cylinder 111 is bolted to the bottom of the hopper 110, a second motor 112 is bolted to the outside of the valve cylinder 111, and the output end of the second motor 112 is connected to the butterfly plate 113 through a shaft passing through the inside of the valve cylinder 111.

[0030] The above scheme achieves material storage and flow regulation through the bolted connection between the hopper and the valve cylinder, precisely controls the feeding speed by driving the disc plate with a second motor, and maintains flexible adjustment of the discharge direction through the bearing connection between the insertion tube and the rotating tube.

[0031] In this embodiment, preferably, the bottom end of the valve cylinder 111 is bolted with an insertion tube 114, the insertion tube 114 is mounted in the rotating tube 115 by a bearing, so that the insertion tube 114 extends further in the rotating tube 115, and a discharge connector 116 is fixedly installed at the end of the rotating tube 115.

[0032] The above scheme achieves sealing and protection of the feed inlet through the bolted connection between the cylinder cover and the feed cylinder, guides the raw material to be evenly distributed through the feed connector, and uses a third motor to drive the scraper and brush to dynamically clean the surface of the filter screen.

[0033] In this embodiment, preferably, a cylinder cover 117 is bolted to the top of the first filter cylinder 101, a feed cylinder 118 is bolted to the top of the cylinder cover 117, a feed connector 119 is fixedly installed on the side of the feed cylinder 118 away from the cylinder cover 117, and a third motor 120 is bolted to the end of the feed cylinder 118 away from the cylinder cover 117.

[0034] The above scheme uses a third motor to coaxially drive two sets of scrapers to rotate synchronously. The first set of scrapers removes large particles trapped by the first filter screen, and the second set of scrapers removes medium-sized particles trapped by the second filter screen, thus maintaining the efficiency of two-stage filtration.

[0035] In this embodiment, preferably, the conveying end of the third motor 120 passes through the first filter cylinder 101 and the second filter cylinder 102 via a shaft and is connected to two sets of scrapers 121. Brush bristles 122 are fixedly installed on one side of each scraper 121, and the brush bristles 122 are respectively attached to the filter screen plate 103.

[0036] The above solution adapts to multi-directional material discharge requirements by combining the inclined design of the discharge joint with the rotational freedom of the rotating tube, and achieves residue-free conveying of high-viscosity materials through gravity sliding and tube rotation assistance.

[0037] In this embodiment, a filtration device for producing nylon thermal insulation strip masterbatch is used. Under the continuous suction of the negative pressure device connected to the suction connector 107, the nylon thermal insulation strip masterbatch raw material enters the feed cylinder 118 through the feed connector 119. At this time, the raw material is evenly adsorbed and spread evenly on the upper surface of the first set of filter screen plates 103 inside the first filter cylinder 101. Simultaneously, the third motor 120 starts and synchronously drives the two sets of scrapers 121 to rotate through the drive shaft passing through the first filter cylinder 101 and the second filter cylinder 102. The bristles 122 at the bottom of the first set of scrapers 121 closely adhere to the surface of the first filter screen plate 103 in a circular motion trajectory, continuously scraping and brushing particles in the raw material with a particle size larger than the mesh size. Large particles are pushed into the first set of outlets 104 and discharged outwards through the first set of discharge connectors 105, completing the first stage of large particle interception. Smaller particles that are not intercepted by the first stage of filtration penetrate the mesh of the first set of filter screens 103 under the combined action of negative pressure suction and gravity, and enter the interior of the second filter cylinder 102 with the airflow. These particles are accelerated by negative pressure in the second filter cylinder 102 and collide with the surface of the second set of filter screens 103. Medium-sized particles are trapped on the second set of filter screens 103. The second set of scrapers 121 driven by the third motor 120 rotates in the same direction as the first set of scrapers 121 through coaxial transmission, pushing the trapped particles into the second set of outlets 104 for discharge. The connector 105 discharges in a directional manner, completing the second stage of medium particle screening. The remaining material after two stages of filtration (including small particles and powder) falls vertically into the feed hopper 110 under gravity. At this time, some ultrafine powder is carried by the airflow to the surface of the rotating filter element 109 due to negative pressure adsorption. The first motor 108 drives the rotating filter element 109 to rotate at a preset speed. Under centrifugal force, the micro-powder adsorbed on the surface of the rotating filter element 109 is thrown out tangentially, completing the third stage of micro-powder separation. Inside the valve cylinder 111 at the bottom of the feed hopper 110, the second motor 112 controls the opening angle of the butterfly plate 113 to adjust the material falling speed. After the material enters the insertion tube 114 through the valve cylinder 111, it passes through the insertion tube 114 and the rotating tube 110. The bearing connection structure between 15 achieves a frictionless transition. The discharge connector 116 adapts to downstream equipment interfaces in different spatial orientations through the continuous rotation capability of the rotating tube 115, ensuring that the discharge direction can be adjusted as needed. The material is discharged by sliding under its own weight within the discharge connector 116. Throughout the process, the negative pressure system maintains an adjustable suction strength. The three sets of motors achieve dynamic balance between the cleaning of the scraper 121, the centrifugation of the filter element, and the rotation of the discharge through coordinated control. The three-stage filtration achieves gradient separation for large particles, medium particles, and micro powders respectively. The multi-directional connection design of the discharge connector 116 significantly reduces the limitations of pipeline layout. The centrifugal separation function of the rotating filter element 109 effectively removes ultrafine powders, ensuring the cleanliness of continuous production of high-viscosity nylon masterbatch.
