Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of extruder device, and particularly relates to an extruder device. BACKGROUND

[0002] The filter screen replacement mode of some extruders usually needs to be carried out during shutdown, and the operation process is complicated, including the steps of disassembling a die head, cleaning, replacing a new filter screen, re-heating, and pulling a blank, etc. The whole process takes dozens of minutes at least or several hours at most. For example, during the operation of a rubber extruder, as the sundries on the filter screen gradually accumulate, the die head pressure increases and the flow decreases, when the pressure exceeds a certain value, the filter screen will be broken and lose the filtering effect, at this time, the filter screen needs to be replaced during shutdown, and the operation process from replacing the filter screen to re-extruding lasts for dozens of minutes or even several hours. Since the filter screen needs to be replaced during shutdown, the production is interrupted, and the production efficiency of the extruder is affected. Frequent replacement of the filter screen will cause the loss of raw materials and the waste of energy. After the filter screen is replaced, sundries will still remain in the extruder, so that the replaced filter screen will be quickly blocked by the sundries.

[0003] There are also some extruders that can replace the filter screen without shutdown, such as the double extruder for replacing the filter screen without shutdown with the application number 201210067135.0. The above-mentioned double extruder for replacing the filter screen without shutdown needs two extruders, and has high cost and complex structure. CONTENT OF THE UTILITY MODEL

[0004] One of the technical problems to be solved by the present application is that the existing extruder device has complex structure and high cost.

[0008] In some embodiments, at an end away from the bottom wall of the mounting groove, the inner wall of the mounting groove has an inwardly extending step, and one side of the limiting plate close to the bottom wall of the mounting groove has a second step extending to both sides.

[0009] In some embodiments, the limiting plate has a placing groove, the filter plate is arranged in the placing groove, and in the thickness direction of the limiting plate, the placing groove has a first through hole, and the bottom wall of the mounting groove of the mounting base plate has a second through hole arranged in correspondence with the first through hole.

[0031] As shown in the drawings: Figures 1 to 5 In some embodiments, an extruder device is provided, comprising: an extruder assembly 10, a pipeline assembly 20 and a filter assembly 30. The pipeline assembly 20 comprises a first main line 21, a first branch line structure 22, a second branch line structure 23 and a second main line 24, the first end of the first main line 21 is in communication with the extruder assembly 10, the first end of the first branch line structure 22 and the first end of the second branch line structure 23 are both connected to the second end of the first main line 21, the second end of the first branch line structure 22 and the second end of the second branch line structure 23 are both connected to the first end of the second main line 24, and the second end of the second main line 24 extends outward to an external structure. The filter assembly 30 comprises a first filter structure 31 and a second filter structure 32, the first filter structure 31 is arranged on the first branch line structure 22, the first filter structure 31 has a plurality of first filter parts, each first filter part is switchable on the first branch line structure 22, and the second filter structure 32 is arranged on the second branch line structure 23, the second filter structure 32 has a plurality of second filter parts, each second filter part is switchable on the second branch line structure 23.

[0032] By setting the first branch line structure 22 and the second branch line structure 23, the switching of the two branch lines can be realized. In addition, a plurality of filter structures are arranged on each branch line structure, and the switching between different filter parts on the same branch line structure can also be realized, for example, the first branch line structure 22 is continuously operated, and different filter parts on the first filter structure 31 are quickly switched. Such a structure further expands the versatility of the extruder device, for example, when different colored materials are used, the switching between the first branch line structure 22 and the second branch line structure 23 is used, and when the filter part of the first filter structure 31 is blocked during operation, another filter part of the first filter structure 31 is quickly switched to work. The above structure can be realized by using one extruder. The technical scheme of the present embodiment effectively solves the problems of complex structure and high cost of the extruder device in the prior art.

[0033] As shown in the drawings: Figures 3 to 5As shown in the drawings, in some embodiments, the first filter structure 31 comprises a mounting base plate 311, a plurality of filter plates 312 and a plurality of limiting plates 313, the mounting base plate 311 has a plurality of mounting grooves, the filter plates 312 are arranged between the mounting grooves and the limiting plates 313, the plurality of filter plates 312 are arranged in one-to-one correspondence with the plurality of mounting grooves, and the plurality of limiting plates 313 are arranged in one-to-one correspondence with the plurality of mounting grooves. The above structure is compact and convenient to operate. In use, the filter plates 312 are placed in the mounting grooves, the limiting plates 313 and the bottom plate of the mounting grooves jointly constrain the filter plates 312, the fluid passes through the first through holes of the limiting plates 313, the filter channels of the filter plates 312, and the second through holes of the mounting base plate 311, and the substances that need to be filtered are filtered by the filter plates 312.

[0034] As shown in the drawings, Figures 3 to 5 In some embodiments, one side of the mounting groove penetrates the side edge of the mounting base plate 311 to form an insertion opening of the limiting plate 313, and the limiting plate 313 and the side wall of the mounting groove have mutually matched clamping steps. When the filter assembly 30 is working, taking the first filter structure 31 as an example: the mounting base plate 311, the filter plates 312 and the limiting plates 313 are matched together, and the limiting plates 313 cannot be detached from the mounting base plate 311 by the clamping steps of the limiting plates 313 and the side wall of the mounting groove. It should be noted that the filter assembly 30 also comprises an operating handle (the operating handle in the drawings is an operating rod), and an operator can realize switching between different filter parts of the same filter structure by pushing and pulling the operating handle. After switching, the branch structure can be sealed by extruding the filter assembly 30, or can be sealed by the connection of the flange plate, which is acceptable. The sealing requirement of the present application is not very high, and a small amount of leakage is acceptable as long as the leaked substances can be collected.

[0035] As shown in the drawings, Figures 3 to 5 In some embodiments, at one end away from the bottom wall of the mounting groove, the inner wall of the mounting groove has a first step extending inward, and the side of the limiting plate 313 close to the bottom wall of the mounting groove has a second step extending to both sides. The above structure is compact and convenient to match. During installation or removal, the filter plates 312 and the limiting plates 313 can be pushed and pulled, which makes the installation and removal more efficient. It should be noted that, taking the same filter structure as an example, after the first filter structure 31 is switched by pushing and pulling, the filter parts that are not working can be operated, such as cleaning, maintenance, replacement of filter plates 312, etc.

[0036] As shown in the drawings, Figures 3 to 5As shown in the drawings, in some embodiments, the limiting plate 313 has a placement groove, the filter plate 312 is arranged in the placement groove, and the placement groove has a first through hole in the thickness direction of the limiting plate 313. The bottom wall of the mounting groove of the mounting seat plate 311 has a second through hole arranged correspondingly to the first through hole. The limiting plate 313 has a placement groove, and the filter plate 312 is arranged in the placement groove, so that the structure is more compact, and the filter plate 312 is located in the placement groove, so that the filter plate 312 does not interfere with the mounting seat plate 311 when the filter part is quickly replaced. It should be noted that in the present embodiment, the thickness of the filter plate 312 is consistent with the height of the placement groove or the thickness of the filter plate 312 is slightly smaller than the height of the placement groove, and the cross section of the placement groove is circular, and correspondingly the filter plate 312 is also circular. As other embodiments, the placement groove can be oval, rectangular, etc., so as to limit the circumferential direction of the filter plate 312, that is, the filter plate 312 cannot rotate.

[0037] As shown in the drawings, Figure 4 In some embodiments, each filter plate 312 is a sieve plate. The above structure has low processing cost and is convenient to disassemble and assemble. The sieve plate has a plurality of sieve holes, and the sieve holes can be adjusted as needed. For example, if larger sieve holes are needed, a sieve plate with larger sieve holes can be replaced, and if smaller diameter sieve holes are needed, a sieve plate with smaller sieve holes can be replaced.

[0038] In the technical solution of some embodiments, the two sides of the mounting seat plate 311 and the circumferential outer side of each mounting groove have a sealing groove, and a sealing ring is arranged in the sealing groove. The sealing ring is exposed by 1 / 4 (diameter) of the mounting groove, so that the sealing ring is not easy to fall out of the sealing groove during pushing and pulling.

[0039] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the pipeline assembly 20 further comprises a first three-way valve 25 and a second three-way valve 26. The first three-way valve 25 is in communication with the second end of the first main line 21, the first end of the first branch line structure 22 and the first end of the second branch line structure 23. The second three-way valve 26 is in communication with the first end of the second main line 24, the second end of the first branch line structure 22 and the second end of the second branch line structure 23. The first three-way valve 25 and the second three-way valve 26 can realize switching between the first branch line structure 22 and the second branch line structure 23. It should be noted that as other embodiments, two valves can be arranged on the first branch line structure 22, that is, one valve is arranged at the front end and the rear end of the first branch line structure 22, and two valves can also be arranged on the second branch line structure 23, that is, one valve is arranged at the front end and the rear end of the second branch line structure 23.

[0040] As shown in the drawings, Figure 2As shown in the drawings, in some embodiments, the first branch structure 22 comprises a first variable-diameter section, which gradually increases in diameter in the direction from the first three-way valve 25 to the first filtering structure 31. The first filtering structure 31 is installed at a position with a larger diameter, which avoids clogging and reduces resistance. It should be noted that the second branch structure 23 comprises a second variable-diameter section, which gradually increases in diameter in the direction from the first three-way valve 25 to the second filtering structure 32.

[0041] As shown in the drawings, Figure 2 In some embodiments, the first variable-diameter section has a small-diameter end with a diameter of d and a large-diameter end with a diameter of D, and D is 1.8 to 4.2 times of d. The above structure can avoid excessive waste of materials and effectively reduce resistance and avoid clogging of the filtering structure. In some embodiments, the diameter D of the large-diameter end of the first variable-diameter section is twice the diameter d of the small-diameter end of the first variable-diameter section.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

Those skilled in the art should understand that the above embodiments can be modified or some technical features can be replaced equivalently without departing from the scope and spirit of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
