Description

Technical Field

[0001] This utility model relates to the field of modified plastics processing technology, and in particular to a mixing device for the production of modified plastics. Background Technology

[0002] Modified plastics refer to plastic products that have been processed through methods such as filling, blending, and reinforcement on the basis of general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness.

[0003] Patent application number CN202322414689.X discloses a modified plastic mixing device, including: a base, a top plate, a mixing bucket, a fixing frame, and a stirrer; the base has a placement groove in the middle, the top plate is slidably disposed in the placement groove, the mixing bucket is disposed on the side of the top plate away from the placement groove, the mixing bucket has a mixing trough in the middle, the fixing frame is connected to the base, and the stirrer is rotatably disposed on the fixing frame, with at least a portion of the stirrer disposed in the mixing trough. Thus, when the user uses the modified plastic mixing device for mixing, the top plate can be driven to lift the mixing bucket and move it up and down, causing the mixing bucket to move closer to or away from the fixing frame. This allows control over the depth to which the stirrer extends into the mixing trough, enabling uniform mixing of materials at different depths within the mixing trough. This results in better and more uniform mixing of the materials in the mixing trough, significantly reducing mixing time and improving the mixing efficiency of the modified plastic mixing device.

[0004] In actual implementation, after mixing is completed, the mixing drum needs to be cleaned to prevent the material adhering to the drum from affecting the next mixing operation. However, after the agitator mixes the material, material also adheres to its surface. Since the agitator is directly rotated and mounted on the fixed frame, it is difficult to remove and there is no suitable cleaning device. Therefore, it is difficult to effectively clean the agitator. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for the production of modified plastics, which, by setting up a cleaning device, can simultaneously clean the agitator and the mixing tank, thereby improving cleaning efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A mixing device for producing modified plastics includes a base, a placement groove disposed on the top of the base, a movable block disposed in the placement groove and a telescopic device for driving the movable block to move vertically, a mixing tank movably disposed on the top of the movable block, a fixed frame disposed on the top of the base, and a stirrer and a cleaning device disposed on the fixed frame.

[0008] The fixing frame includes a vertical plate and a top plate disposed on the vertical plate;

[0009] The cleaning device includes multiple nozzles mounted on the top plate, a first water pipe connected to the water inlet of each nozzle, a second water pipe connected to the common water inlet of the multiple first water pipes, and a water tank connected to the water inlet of the second water pipe.

[0010] The top wall of the mixing tank can contact the top plate; the side wall of the mixing tank is provided with a liquid outlet pipe.

[0011] Preferably, the stirrer includes a motor disposed at the top of the top plate, a rotating shaft disposed below the top plate, and a plurality of stirring rods disposed on the rotating shaft; the bottom end of the stirring rod is fixedly connected to the output end of the motor.

[0012] Preferably, the nozzles are evenly distributed circumferentially outside the rotating shaft.

[0013] Preferably, the telescopic device includes a hydraulic rod disposed on the bottom wall of the placement groove, and the telescopic end of the hydraulic rod is connected to the bottom end of the moving block.

[0014] Preferably, the outer wall of the movable block is provided with a plurality of sliders, and the inner wall of the placement groove is provided with a vertical sliding groove that slides in cooperation with the sliders.

[0015] Preferably, a first arc-shaped plate is fixedly provided on the top wall of the movable block, an arc-shaped groove is provided at the top of the movable block, and a second arc-shaped plate is movably provided in the arc-shaped groove.

[0016] Preferably, the mixing tank has at least two handles on its side wall.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By installing a cleaning device consisting of multiple nozzles, a first water pipe, a second water pipe, and a water tank on a fixed frame, the mixing tank and the agitator can be cleaned after mixing is completed and the material in the mixing tank is removed. Specifically, the mixing tank is placed on a moving plate, and then the moving plate is raised so that the mixing end of the agitator is located inside the mixing tank. Then, water from the water tank enters the nozzles sequentially through the second water pipe and the first water pipe, and is sprayed out along the nozzles to wash down the material adhering to the mixing end of the agitator and the inner wall of the mixing tank, thereby achieving the purpose of cleaning the agitator and the mixing tank simultaneously.

[0019] By limiting the top of the mixing tank to contact the top plate, the mixing tank can be moved upwards to contact the top plate during the cleaning process, so that a relatively closed area is formed between the mixing tank and the top plate. This avoids the technical problem of some water splashing out along the large gap between the mixing tank and the top plate due to water spraying and collision with the agitator or mixing tank during the cleaning process.

Detailed Implementation

[0025] Example 1

[0026] A mixing device for the production of modified plastics, such as Figure 1 As shown, it includes a base 1, a placement groove 2 disposed on the top of the base 1, a movable block 3 disposed in the placement groove 2 and a telescopic device for driving the vertical displacement of the movable block 3, a mixing tank 4 movably disposed on the top of the movable block 3, a fixed frame disposed on the top of the base 1, and a stirrer and a cleaning device disposed on the fixed frame; Figure 1 As shown, the fixing frame includes a vertical plate 10 and a top plate 9 disposed on the vertical plate 10; as Figure 1 and Figure 3 As shown, the cleaning device includes multiple nozzles 5 mounted on the top plate 9, a first water pipe 6 connected to the water inlet of each nozzle 5, a second water pipe 7 connected to the common water inlet of the multiple first water pipes 6, and a water tank connected to the water inlet of the second water pipe 7. A water pump is mounted on the second water pipe 7. Both the water pump and the water tank are existing technologies and are not shown in the figure. The second water pipe 7 is a flexible hose. Further, as... Figure 2As shown, the top wall of the mixing tank 4 can contact the top plate 9; the side wall of the mixing tank 4 is provided with a liquid outlet pipe with a valve (existing technology, not shown in the figure). Further, as... Figure 1 and Figure 3 As shown, the stirrer includes a motor 12 mounted at the top of the top plate 9, a rotating shaft 13 mounted below the top plate 9, and multiple stirring rods 14 mounted on the rotating shaft 13; the bottom ends of the stirring rods 14 are fixedly connected to the output ends of the motor 12. Further, as... Figure 1 As shown, the telescopic device includes a hydraulic rod 15 disposed on the bottom wall of the placement groove 2, and the telescopic end of the hydraulic rod 15 is connected to the bottom end of the moving block 3.

[0027] Working principle: The modified plastic raw material is added into the mixing tank 4, and then the mixing tank 4 is placed on the moving block 3. Alternatively, in practice, the mixing tank 4 can be placed on the moving block 3 first, and then the modified plastic raw material is added into the mixing tank 4. Next, the hydraulic rod 15 is activated, causing the moving block 3 to move upwards within the placement slot 2 until the stirring rod 14 is in the optimal position within the mixing tank 4. Then, the motor 12 is activated, causing the rotating shaft 13 to rotate, which in turn causes the stirring rod 14 to rotate, thus achieving material mixing. After mixing is complete, remove the material. Then, place the mixing tank 4 back on the moving block 3 and activate the hydraulic rod 15 to move the moving block 3 and the mixing tank 4 upwards until it contacts the top plate 9. Then, activate the water pump. Under the action of the water pump, water from the tank flows sequentially through the second water pipe 7 and the first water pipe 6 into the nozzle 5 and is sprayed out along the nozzle 5 to flush down the material adhering to the rotating shaft 13, the stirring rod 14, and the inner wall of the mixing tank 4, thus simultaneously cleaning the agitator and the mixing tank 4. The turbid water in the mixing tank 4 is discharged through the liquid outlet pipe.

[0028] Through the synergistic effect of the above-mentioned devices, the agitator and mixing tank 4 can be cleaned simultaneously, thereby improving cleaning efficiency.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1 As shown, the nozzles 5 are evenly distributed circumferentially outside the rotating shaft 13, that is, the nozzles 5 are uniformly arranged around the outside of the rotating shaft 13 to rinse the agitator in all directions. Further, as... Figure 1 and Figure 2As shown, the outer wall of the movable block 3 is provided with multiple sliders 16, and the inner wall of the placement groove 2 is provided with a vertical groove 17 that slides and engages with the sliders 16. In this design, by setting the sliders 16 and the vertical groove 17, the movable block 3 can be limited to ensure that it always moves vertically, while avoiding direct contact between the movable block 3 and the inner wall of the placement groove 2, thus preventing wear and tear and improving service life.

[0031] Furthermore, such as Figure 1 , 2 and Figure 4 As shown, a first arc-shaped plate 18 is fixedly installed on the top wall of the movable block 3, and an arc-shaped groove (existing technology, not shown in the figure) is provided at the top of the movable block 3. A second arc-shaped plate 19 is movably installed in the arc-shaped groove, and the size of the arc-shaped groove is adapted to the second arc-shaped plate 19. Specifically, when the mixing bucket 4 is placed on the movable block 3, the side wall of the mixing bucket 4 is first made to fully fit with the first arc-shaped block. Then, the second arc-shaped block is inserted into the arc-shaped groove. After insertion, the second arc-shaped block can also fit with the side wall of the mixing bucket 4. The first arc-shaped plate 18 and the second arc-shaped plate 19 can securely limit the mixing bucket 4 on the movable block 3, ensuring that the mixing bucket 4 can always be limited on the movable block 3 during stirring and vertical displacement, and preventing horizontal displacement. Furthermore, the side wall of the mixing bucket 4 is provided with at least two handles (existing technology, not shown in the figure) to facilitate moving the mixing bucket 4.
