Description

Technical Field

[0001] This utility model relates to the field of masterbatch production technology, and in particular to an acrylate masterbatch production device with filtration. Background Technology

[0002] Acrylic ester masterbatch is a plastic processing aid composed of excessive amounts of chemical additives, carrier resins, and dispersants. It forms aggregates by uniformly loading various additives and fillers into the resin. In the plastic processing process, masterbatch is produced through processes such as mixing, melting, and extrusion. It is easy to operate and uniformly dispersed. Its production process is generally carried out by an extruder in conjunction with cooling equipment and pelletizing equipment.

[0003] The existing acrylic masterbatch production process has the following drawbacks: In the extrusion production of acrylic masterbatch using an extruder, in order to improve molding quality, a filter assembly is usually installed at the extrusion end. In actual use, the filter assembly often gets clogged and needs to be cleaned and replaced regularly. When replacing it, the temperature of the newly inserted filter assembly is low, which causes the temperature of the molten material near the filter to drop as well. As a result, the quality of the extruded product will be defective for a period of time after the filter plate is replaced, affecting the overall quality. To address this, we propose an acrylic masterbatch production device with a filter. Utility Model Content

[0004] The main objective of this invention is to provide an acrylic masterbatch production device with a filter. By using a discharge filter mechanism installed at the extrusion end of the extruder, the filter components can be preheated when they are replaced, reducing the impact on production quality and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An acrylate masterbatch production apparatus with filtration includes an extruder and a discharge filtration mechanism. The discharge end of the extruder is provided with a discharge filtration mechanism, which includes a die base, a mounting base, a through cavity, a heating wire, an operating hole, a hydraulic cylinder, a piston rod, a positioning seat, and a filter plate. The extruder discharge end is detachably connected to the die base, and mounting bases are integrally formed at both the upper and lower ends of the die base. Each mounting base has a through cavity on the side facing the die base. A heating wire is embedded in one end of each mounting base, and an operating hole is provided on the surface of the mounting base away from the heating wire. A hydraulic cylinder is installed at the top of the mounting base on the top of the die base, and a piston rod inserted into the die base is provided at the power output end of the hydraulic cylinder. A symmetrically arranged positioning seat is installed at the bottom end of the piston rod, and a filter plate is fixed to the inner wall of each positioning seat by bolts.

[0007] Furthermore, it also includes a water-cooling mechanism. The extruder discharge end is equipped with a water-cooling mechanism, which includes a water-cooling box, a water tank, a partition, a drain pipe, a return water pipe, a water pump, a supply water pipe, a branch pipe, and a spray pipe. The bottom of the water-cooling box is welded to a water tank, and a partition is obliquely welded inside the water tank. A drain pipe connected to an external chiller unit is installed on the side of the water tank near the bottom of the partition. A return water pipe extending to the bottom of the partition is welded to the side of the water tank away from the drain pipe. A water pump is installed inside the water tank, and a supply water pipe extending to the side of the water-cooling box is installed at the pump discharge end. A diversion pipe is installed at the end of the water supply pipe, and the diversion pipe is inserted into the upper and lower ends of the water-cooled box. The water tank is filled with cooling water. The extruded material enters the water-cooled box for transportation. The water pump draws out the cooling water and sprays it into the water-cooled box through the water supply pipe and diversion pipe, and sprinkles it on the surface of the material to perform rapid water cooling treatment and accelerate the material setting. The used cooling water falls into the top of the partition and is discharged into the chiller unit through the drain pipe near the bottom of the partition for cooling. Then it flows back into the water tank through the return water pipe for recycling. Through the water cooling mechanism, the cooling and setting of the material is accelerated.

[0008] Furthermore, the extruder is equipped with a main hopper at the feed end and a secondary hopper at the top of the extrusion end; the main hopper is loaded with and supplied with the main raw materials, while the secondary hopper can be loaded with petrochemical resins, metal oxides and other functional additives, which are supplied into the extruder during the extrusion production process.

[0009] Furthermore, a connecting rod is vertically welded between adjacent sides of the positioning seat surface; the positioning seats are fixed together by the connecting rod, so that the two sets of positioning seats can be linked together.

[0010] Furthermore, a control panel is installed on one side of the extruder surface. The control panel is connected to the control terminals of the heating wire, hydraulic cylinder, and water pump. The control panel adjusts the current of the heating wire by changing the power supply voltage, thereby controlling its temperature. The control panel monitors the status of the hydraulic system and dynamically adjusts the proportional valve by combining a closed-loop control algorithm to drive the hydraulic cylinder to achieve precise displacement control.

[0011] Furthermore, the water-cooled box has inlet and outlet holes on both sides corresponding to the position of the extruder discharge end. Conveying rollers are installed at both ends inside the water-cooled box. A pelletizer is installed on the outer wall of the water-cooled box away from the extruder. The material enters and exits the water-cooled box through the inlet and outlet holes. The conveying rollers play an auxiliary role in conveying the material under the action of the external power component. The pelletizer granulates the cooled material.

[0012] Compared with the prior art, this utility model has the following advantages: Various raw materials for producing acrylate masterbatch are fed into the extruder through the main hopper and auxiliary hopper. The extruder mixes, melts, and extrudes these raw materials. A die holder is provided at the discharge end of the extruder to control the material forming specifications. The hydraulic cylinder drives the movement of the positioning seat and its internal filter plates through the movement of the piston rod. When one set of filter plates is located inside the die holder for filtration, another set of filter plates is located inside the mounting seat at the top or bottom of the die holder. The filter plates can be disassembled, cleaned, and replaced without affecting production. When a new filter plate is placed inside the positioning seat for use, the heating wire inside the corresponding mounting seat is energized to generate… High-temperature radiation heats the filter plates to raise their temperature. After heating, the plates are positioned under hydraulic control, which reduces the temperature drop of the molten material on the filter plate side and ensures the quality of masterbatch forming. The water tank stores cooling water. The extruded material enters the water-cooling box and is transported. The water pump draws out the cooling water and sprays it into the water-cooling box through the water supply pipe and the distribution pipe. The water is poured onto the surface of the material for rapid water cooling and accelerates the material setting. The used cooling water falls onto the top of the partition and is discharged into the chiller unit through the drain pipe near the bottom of the partition for further cooling. Then, it flows back into the water tank through the return pipe for recycling. The water cooling mechanism accelerates the cooling and setting of the material. Attached Figure Description

A drain pipe 306 connected to an external chiller unit is installed on the side of the water tank 302 near the bottom of the partition 305. A return water pipe 307 extending to the bottom of the partition 305 is welded to the side of the water tank 302 away from the drain pipe 306. A water pump 308 is installed inside the water tank 302, and an extension pipe extending to the water-cooling box 302 is installed at the discharge end of the water pump 308.

The water tank 302 is filled with cooling water. The extruded material enters the water cooling box 301 for transportation. The water pump 308 draws out the cooling water and sprays it into the water cooling box 301 through the water supply pipe 309 and the diversion pipe 310 via the spray pipe 311. The water is poured onto the surface of the material to perform rapid water cooling treatment and accelerate the shaping of the material. The used cooling water falls into the top of the partition 305 and is discharged into the chiller unit for cooling through the drain pipe 306 near the bottom of the partition 305. Then it flows back into the water tank 302 through the return water pipe 307 for recycling. Through the water cooling mechanism 3, the cooling and shaping of the material is accelerated.

[0021] The extruder 1 is equipped with a main hopper 201 at its feed end and a secondary hopper 202 at the top of its extrusion end.
