Description

Technical Field

[0001] This utility model relates to a filtration device, and more particularly to a raw material filtration device for the production of thermal insulation materials, belonging to the technical field of thermal insulation material production equipment. Background Technology

[0002] Thermal insulation materials are functional materials used to reduce heat transfer and are widely used in construction, industrial equipment, and cold chain transportation. Their core performance indicator is thermal conductivity. In the production of thermal insulation materials, raw materials typically require filtration, a crucial step to ensure product quality, production stability, and equipment safety.

[0003] Impurities in insulation materials can lead to defects such as voids and cracks, reducing insulation performance and mechanical strength. Therefore, filtration devices are needed to remove foreign matter such as metal scraps, sand, plastic fragments, and packaging residues that may be mixed in the raw materials used in the production of insulation materials, such as mineral wool, broken glass, and polyol / isocyanate for polyurethane. Furthermore, raw material filtration can ensure the stability of the melting process for fibrous materials such as rock wool and glass wool.

[0004] In existing technologies, when filtering thermal insulation material raw materials, sieving is generally performed using a mechanical screening screen. However, during sieving, impurities easily accumulate on the screen, causing blockage and resulting in poor filtration. Furthermore, the uniformity of the feed cannot be controlled, leading to poor filtration performance, inability to guarantee continuous filtration, and the inability to link the reciprocating movement of the filter with the uniformity of the feed. This results in complex operation, low filtration efficiency, and high equipment maintenance costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material filtration device for the production of thermal insulation materials that can effectively improve the raw material screening efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A raw material filtration device for producing thermal insulation materials includes a placement plate and a connecting shaft. A reciprocating uniform feeding assembly is provided on the outer surface of the connecting shaft.

Preferably, the limiting is provided at the bottom of the filter box with a locking structure that matches the rectangular groove, so that the filter box can slide stably through the rectangular groove. A filter assembly is provided inside the filter box.

[0008] Furthermore, the lower surface of the rack is in contact with the upper surface of the placement plate, and the upper surface of the rack meshes with the outer surface of the gear.

[0009] Furthermore, a fixing plate is fixedly installed on the upper surface of the extension side of the placement plate, and a servo motor is fixedly installed on the front side of the fixing plate.

[0017] Next, the technical solutions of the utility model will be clearly and completely described in conjunction with the drawings and specific embodiments.

[0018] Such as Figure 1-4As shown, a raw material filtration device for producing thermal insulation materials includes a placement plate 1 and a connecting shaft 603. A reciprocating uniform feeding assembly 6 is provided on the outer surface of the connecting shaft 603. The reciprocating uniform feeding assembly 6 includes a gear 604, a connecting block 605, a rack 606, a first pulley 607, a connecting belt 608, a second pulley 609, a connecting rod 610, and a feeding blade 611. The gear 604 is fixedly connected to one end of the connecting shaft 603. The bottom of the connecting block 605 is in contact with the top of the placement plate 1. The side of the rack 606 is fixedly connected to the connecting block 605. The first pulley 607 is fixedly connected to the other end of the connecting shaft 603. The first pulley (607) is connected to the second pulley (609) via a connecting belt (608). The end of the connecting rod (610) is fixedly connected to the second pulley (609), and multiple evenly distributed feed blades (611) are fixedly provided on the outside of the connecting rod (610). The lower surface of the rack (606) is in contact with the upper surface of the placement plate (1). The rack (606) meshes with the gear (604). A fixing plate (601) is fixedly installed on the upper surface of the extension side of the placement plate (1). A servo motor (602) is fixedly installed on the front side of the fixing plate (601). One end of the output shaft of the servo motor (602) is fixedly installed with one end of the connecting shaft (603). A limiting block (7) that is slidably connected to the rack (606) is fixedly installed on the upper surface of the placement plate (1).

[0019] Specifically, the output shaft of the servo motor 602 drives the connecting shaft 603 to rotate, which in turn drives the gear 604 and pulley 607 to rotate. The gear 604 meshes with the rack 606, causing the rack 606 to reciprocate linearly under the limiting action of the limiting block 7, thus allowing the filter box 3 to move back and forth, achieving a high-efficiency filtration effect. The connecting shaft 603 drives the pulley 607 to rotate, which in turn drives the pulley 609 to rotate via the connecting belt 608. The pulley 609 then drives the connecting rod 610. The rotating and feeding blades 611 rotate to achieve the effect of stirring the raw materials and promoting uniform feeding; the servo motor 602 drives the connecting shaft 603 to simultaneously drive the gear 604 and the pulley 607 to rotate, realizing that one power source can simultaneously drive two actions: reciprocating movement and uniform feeding, which helps to improve the power utilization efficiency of the equipment, reduce energy consumption, and simplify the equipment structure; the sliding connection and limiting effect of the rack 606 by the limiting block 7 ensures the stability and straightness of the rack 606 during reciprocating movement.

[0020] like Figure 1 and Figure 2As shown, a rectangular groove 2 is provided on the upper surface of the placement plate 1, and a filter box 3 with an internal filter assembly 4 is slidably arranged through the rectangular groove 2. The filter assembly 4 includes a filter screen 401, a raw material collection box 402, an impurity collection box 403, and a handle 404. The filter screen 401 is fixedly installed inside the filter box 3 on all four sides. The side of the raw material collection box 402 is fixedly connected to the filter box 3. The outer surface of the impurity collection box 403 is slidably connected to the inner wall of the filter box 3. The handle 404 is fixedly installed on the surface of the impurity collection box 403. A feed box 5 is fixedly installed on the filter box 3, and the connecting rod 610 is rotatably arranged on the inner wall of the feed box 5.

[0021] Specifically, by setting a filter screen 401 inside the filter box 3, when the raw material enters the filter box 3 from the feed box 5, it will fall onto the filter screen 401. The filter screen 401 can filter the raw material, intercepting qualified raw material above the filter screen 401, while impurities fall through the filter screen 401. By setting a raw material collection box 402 and fixing it to the right side of the filter box 3, the impurities filtered by the filter screen 401 can be easily placed into the impurity collection box 403 for subsequent unified processing, achieving the effect of centralized collection of impurities, keeping the filtration environment clean, and improving filtration efficiency.

[0022] Working principle: During use, the raw material is first fed into the filter box 3 through the feed box 5. Simultaneously, the servo motor 602 drives the connecting shaft 603 to rotate through the electrical connection of the external power source. On one hand, the meshing of the gear 604 and the rack 606 drives the connecting block 605 to move back and forth along the placement plate 1, causing the filter box 3 to vibrate and improve the filtration efficiency. On the other hand, through the transmission of the pulley 607, the connecting belt 608 and the pulley 609, the connecting rod 610 drives the feed blade 611 to rotate at a constant speed in the feed box 5, realizing the uniform feeding of raw materials. At the same time, the limiting block 7 ensures the stability of the movement trajectory of the rack 606. Then, after the raw material is screened by the filter screen 401, the impurity particles fall into the impurity collection box 403. The raw material is then manually or mechanically placed into the raw material collection box 402 after screening for classification and collection.

[0023] The above are merely preferred embodiments of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications will also fall within the protection scope of the present utility model.
