Description

Technical Field

[0001] This utility model relates to the field of recycled plastics, and in particular to a plastic spiral water filtration device. Background Technology

[0002] In the process of recycling plastics, the cleaning process is crucial for removing oil, mud, and residual impurities from the plastic surface, while the water filtration and conveying equipment is the core device for dehydrating the cleaned material. This type of equipment typically uses a screw conveyor structure, filtering and conveying the cleaned plastic material through a filter screen to ensure that the material's moisture content meets the requirements for subsequent drying and processing.

[0003] In existing technologies, water filtration transmission equipment typically includes three components: a spiral feed cylinder, a filter screen, and a water receiving tray. The filter screen and the water receiving tray are used to filter water and guide wastewater discharge, respectively. However, currently, the filter screen and the water receiving tray are mostly installed sequentially on the spiral feed cylinder using fastening bolts. The water receiving tray encloses the filter screen in the cavity formed by it and the spiral feed cylinder. Consequently, when the filter screen becomes clogged due to trapping impurities such as plastic debris, fibers, and silt, maintenance is required. The machine must be stopped first, and the fixing bolts of the water receiving tray must be removed one by one. Finally, the water receiving tray must be removed before the filter screen can be disassembled, cleaned, or replaced. This operation is time-consuming and cannot meet the high-frequency maintenance requirements of filter screens in practical applications.

[0004] Therefore, a plastic spiral water filtration device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic spiral water filtration device that allows the water receiving tray and the filter screen plate to be integrated and quickly disassembled and assembled with the spiral feeding cylinder without bolts, and also allows for separate cleaning of the filter screen plate, thereby shortening the time required for disassembling and assembling the filter screen plate and meeting the high-frequency maintenance needs of the filter screen plate.

[0006] To solve the above-mentioned technical problems, this utility model provides a plastic spiral water filtration device, including a spiral feeding cylinder, a filter screen plate, a water receiving tray, and a connecting structure;

[0007] The bottom of the spiral feed cylinder is provided with an installation port for installing the filter screen plate;

[0008] The filter screen is movably installed inside the water receiving tray and can be separated from the water receiving tray;

[0009] The water receiving tray is detachably connected to the spiral feeding cylinder via the connecting structure, and is used to carry the filter screen plate and engage it with the mounting port;

[0010] The connection structure includes a connecting plate and a limiting post;

[0011] The connecting plate is fixedly installed on the end face of the water receiving tray, and the limiting post is fixedly installed on the outer wall of the spiral feeding cylinder;

[0012] The connecting plate is provided with an L-shaped groove that matches the limiting post;

[0013] When the water receiving tray is vertically aligned with the spiral feeding cylinder and moves horizontally, the limiting post can overlap with the inner top wall of the L-shaped groove.

[0014] Furthermore, the L-shaped groove includes vertical grooves and horizontal grooves that are interconnected;

[0015] When the limiting post is located at the bottom end of the vertical groove, the filter screen plate can just engage with the mounting port;

[0016] When the filter screen plate engages with the mounting port, the water receiving tray can move horizontally relative to the filter screen plate, so that the limiting post is located in the horizontal groove.

[0017] Furthermore, an installation groove is provided on the inner side wall of the water receiving tray, and an installation block matching the installation groove is provided on the outer wall of the filter screen plate;

[0018] The length of the mounting groove in the horizontal direction is greater than the length of the mounting block in the horizontal direction, so that the filter screen plate is clamped by the mounting port, so that when it is kept relatively fixed in the horizontal direction, the water receiving tray can move relative to the filter screen plate in the horizontal direction.

[0019] Furthermore, one end of the mounting groove is open, allowing the filter plate to detach from the water receiving tray in a vertical direction.

[0020] Furthermore, the connecting plate and the water receiving tray are integrally formed.

[0021] Furthermore, the spiral feed cylinder includes a cylinder body, a drive shaft, and auger blades;

[0022] One end of the drive shaft is rotatably mounted inside the cylinder via an output motor, and the other end is rotatably connected to the inner wall of one end of the cylinder.

[0023] The auger blades are mounted on the outer wall of the drive shaft and are used to complete the material conveying and feeding.

[0024] Furthermore, the end of the drive shaft away from the output motor is configured as a hollow structure, and the outer wall of the drive shaft is provided with a one-way nozzle that communicates with the hollow structure;

[0025] One end of the cylinder is provided with an air inlet pipe that communicates with the hollow structure, which is used to provide an air source for the one-way nozzle.

[0026] Furthermore, the cylinder is provided with a feed inlet and a discharge outlet.

[0027] Furthermore, the water receiving tray is made of transparent acrylic sheet.

[0028] Furthermore, the spiral feed cylinder is arranged at an angle.

[0029] Compared with the prior art, the present invention has at least the following beneficial effects:

[0030] By setting a connection structure including a connecting plate and a limiting post, and setting an L-shaped groove on the connecting plate that matches the limiting post, and allowing the filter screen plate to be movably installed in the water receiving tray, when the filter screen plate needs to be installed, the filter screen plate and the water receiving tray can be connected to the spiral feeding cylinder as a whole, and the limiting post and the L-shaped groove complete the limiting. When the filter screen plate needs to be cleaned or replaced, it can also be disassembled as a whole. Since the filter screen plate and the water receiving tray can be separated, after the water receiving tray and the filter screen plate are completely disassembled, the filter screen plate can be cleaned or replaced separately. In other words, through the above settings, the water receiving tray and the filter screen plate can form a whole for boltless quick assembly and disassembly with the spiral feeding cylinder, and the filter screen plate can be cleaned separately, thereby shortening the time required for disassembly and assembly of the filter screen plate and achieving the goal of meeting the high-frequency maintenance needs of the filter screen plate.

Detailed Implementation

[0036] The plastic spiral water filtration device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0037] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0038] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a plastic spiral water filtration device, including a spiral feeding cylinder 1, a filter screen plate 2, a water receiving tray 3, and a connecting structure 4.

[0039] The bottom of the spiral feed cylinder 1 is provided with an installation port 5 for installing the filter screen plate 2. That is, the filter screen plate 2 is detachably installed on the installation port 5 to cooperate with the spiral feed cylinder 1 to complete the work of filtering water and feeding materials.

[0040] The filter screen plate 2 is movably installed inside the water receiving tray 3 and can be separated from the water receiving tray 3 to realize the linkage quick disassembly between the filter screen plate 2 and the water receiving tray 3. That is, the two can be disassembled as a whole, and the filter screen plate 2 can also be detached from the water receiving tray 3 separately, which takes into account both maintenance convenience and structural flexibility, and solves the problem that the filter screen plate 2 and the water receiving tray 3 need to be disassembled layer by layer in the prior art.

[0041] The water receiving tray 3 is detachably connected to the spiral feeding cylinder 1 through the connecting structure 4, and is used to carry the filter screen plate 2 and engage it with the mounting port 5. That is, the water receiving tray 3 drives the filter screen plate 2 to be installed at the mounting port 5, realizing the quick disassembly and installation of the whole.

[0042] In this embodiment, the connection structure 4 includes a connecting plate 41 and a limiting post 42.

[0043] The connecting plate 41 is fixedly installed on the end face of the water receiving tray 3, and the limiting post 42 is fixedly installed on the outer wall of the spiral feeding cylinder 1. Furthermore, the connecting plate 41 is provided with an L-shaped groove 6 that matches the limiting post 42. This allows the water receiving tray 3 to move vertically (i.e.,...) Figure 1 The feed cylinder 1 is connected to the feed cylinder 1 along the Y-axis direction, and along the horizontal direction (i.e., Figure 1 When moving in the X-axis direction, the limiting post 42 can overlap with the top wall of the inner cavity of the L-shaped groove 6.

[0044] It should be noted that when the water receiving tray 3 is vertically aligned with the spiral feeding cylinder 1, the filter screen plate 2 can just engage with the mounting port 5. Since the filter screen plate 2 is movably installed inside the water receiving tray 3, when the water receiving tray 3 moves horizontally, the filter screen plate 2 remains relatively fixed due to the engagement of the mounting port 5, allowing the water receiving tray 3 to move relative to the filter screen plate 2. That is, due to the movable connection between the filter screen plate 2 and the water receiving tray 3, a motion compensation is provided for the horizontal movement of the water receiving tray 3, thereby effectively preventing jamming. Finally, under the action of the L-shaped groove 6 and the limiting post 42, the final installation is completed, and the filter screen plate 2 and the water receiving tray 3 are assembled and disassembled as a whole to complete the spiral feeding cylinder 1.

[0045] This device features a connection structure 4 including a connecting plate 41 and a limiting post 42. An L-shaped groove 6 matching the limiting post 42 is provided on the connecting plate 41, allowing the filter screen plate 2 to be movably installed within the water receiving tray 3. This allows the filter screen plate 2 and the water receiving tray 3 to be considered as a single unit connected to the spiral feeding cylinder 1 when installation is required, with the limiting post 42 and L-shaped groove 6 providing a limiting position. When cleaning or replacement of the filter screen plate 2 is needed, it can be disassembled as a whole. Since the filter screen plate 2 and the water receiving tray 3 can be separated, the filter screen plate 2 can be cleaned or replaced individually after the overall disassembly. In other words, through the above configuration, the water receiving tray 3 and the filter screen plate 2 can form a single unit for boltless, quick assembly and disassembly with the spiral feeding cylinder 1, and the filter screen plate 2 can be cleaned individually. This shortens the time required for disassembling and assembling the filter screen plate 2, thus meeting the high-frequency maintenance requirements of the filter screen plate 2.

[0046] like Figure 3 As shown, in a further embodiment, the L-shaped groove 6 is further defined to improve the connection effect between the water receiving tray 3 and the spiral feeding cylinder 1.

[0047] Specifically, the L-shaped groove 6 includes a vertical groove 61 and a horizontal groove 62 that are interconnected.

[0048] It should be noted that when the limiting post 42 is located at the bottom end of the vertical groove 61, the filter screen 2 can just engage with the mounting port 5. That is, when the water receiving tray 3 moves in the horizontal direction, the filter screen 2 will remain relatively fixed in the horizontal direction.

[0049] It should also be noted that when the filter plate 2 is engaged with the mounting port 5, the water receiving tray 3 can move horizontally relative to the filter plate 2, so that the limiting post 42 is located in the horizontal groove 62. That is, the filter plate 2 and the water receiving tray 3 can be displaced relative to each other in the horizontal direction to meet the requirement that the limiting post 42 is located inside the horizontal groove 62.

[0050] In this embodiment, the installation relationship between the receiving water tray 3 and the filter screen plate 2 is further defined to better ensure that the receiving water tray 3 can move relative to the filter screen plate 2 when it moves horizontally, without jamming or interference, thereby improving the stability of the device operation.

[0051] Specifically, the inner wall of the water receiving tray 3 is provided with an installation groove 31, and the outer wall of the filter screen plate 2 is provided with an installation block 21 that matches the installation groove 31.

[0052] The mounting groove 31 is longer in the horizontal direction than the mounting block 21, so that the filter screen plate 2 is engaged by the mounting port 5. This allows the water receiving tray 3 to move horizontally relative to the filter screen plate 2 while remaining relatively fixed in the horizontal direction. In other words, by setting the mounting groove 31 and the mounting block 21, the water receiving tray 3 provides vertical support for the filter screen plate 2. When the water receiving tray 3 is installed on the spiral feed cylinder 1, the filter screen plate 2 is clamped and fixed between the water receiving tray 3 and the mounting port 5, ensuring its filtration function. Furthermore, since the mounting groove 31 is longer in the horizontal direction than the mounting block 21, when the filter screen plate 2 is fixed in the horizontal direction (i.e., limited by the mounting port 5), the relative movement of the water receiving tray 3 and the filter screen plate 2 in the horizontal direction will not be interfered with, thus achieving the final overlapping and limiting of the horizontal groove 62 and the limiting post 42.

[0053] It should be noted that one end of the mounting groove 31 is open, so that the filter screen plate 2 can be separated from the water receiving tray 3 in the vertical direction. That is, after the filter screen plate 2 and the water receiving tray 3 are disassembled as a whole relative to the spiral feeding cylinder 1, the filter screen plate 2 can be taken out separately for cleaning or replacement, making the operation more convenient.

[0054] To improve the strength of the connection between the connecting plate 41 and the limiting post 42, the connecting plate 41 and the water receiving tray 3 are designed as an integral molding structure.

[0055] In this embodiment, to more clearly illustrate the changes in the connection state between the filter screen plate 2, the water receiving tray 3, and the spiral feeding cylinder 1, a method for installing the filter screen plate 2 is also proposed, which specifically includes the following steps:

[0056] The filter screen plate 2 is installed vertically in the water receiving tray 3, that is, the vertical position of the filter screen plate 2 in the water receiving tray 3 is limited by the mounting block 21 and the mounting groove 31.

[0057] Connect the water receiving tray 3 vertically to the spiral feeding cylinder 1 (i.e., connect the vertical groove 61 to the limiting column 42), and make the filter screen plate 2 face the installation port 5 of the spiral feeding cylinder 1.

[0058] As the limiting post 42 abuts against the bottom wall of the vertical groove 61, the filter screen 2 is just locked into the installation port 5;

[0059] Control the water receiving tray 3 to move horizontally. At this time, the filter screen 2 remains fixed under the limiting action of the installation port 5. That is, the water receiving tray 3 moves horizontally relative to the filter screen 2, so that the limiting post 42 is located in the horizontal groove 62, and the installation is completed.

[0060] Through the above steps, the water receiving tray 3 and the filter screen plate 2 can be connected to the spiral feeding cylinder 1 as a whole. Compared with the existing technology of disassembling the water receiving tray 3 and the filter screen plate 2 in sequence, the time required for disassembling and assembling the filter screen plate 2 can be effectively shortened, so as to meet the high-frequency maintenance needs of the filter screen plate 2.

[0061] like Figure 4 As shown, in other embodiments, the spiral feed cylinder 1 is further defined to further improve the water filtration effect.

[0062] Specifically, the spiral feed cylinder 1 includes a cylinder body 11, a drive shaft 12, and auger blades 13.

[0063] One end of the drive shaft 12 is rotatably mounted inside the cylinder 11 via an output motor, and the other end is rotatably connected to the inner wall of one end of the cylinder 11.

[0064] The auger blades 13 are disposed on the outer wall of the drive shaft 12 and are used to complete the material conveying and feeding.

[0065] It should be noted that the end of the drive shaft 12 away from the output motor is configured as a hollow structure, and the outer wall of the drive shaft 12 is provided with a one-way nozzle 7 that communicates with the hollow structure.

[0066] Furthermore, one end of the cylinder 11 is provided with an air inlet pipe 8 that communicates with the hollow structure, which is used to provide an air source for the one-way nozzle 7, so that when the material is conveyed by the auger blades 13, it will also be subjected to the airflow sprayed by the one-way nozzle 7 to accelerate the discharge of moisture.

[0067] In addition, the one-way nozzle 7 can also be used as an airflow to remove impurities from the filter plate 2. If the operator finds that the filter plate 2 is clogged, gas can be injected directly through the air inlet pipe 8 so that the one-way nozzle 7 sprays air in the direction of the filter plate 2 to complete the function of unclogging the surface of the filter plate 2. This can effectively reduce the number of times the filter plate 2 is disassembled and reduce the frequency of filter plate 2 replacement.

[0068] It should be noted that the airflow output by the one-way nozzle 7 is only applicable when the filter plate 2 is slightly clogged. If the operator finds that the filter plate 2 is severely clogged, it is still necessary to disassemble and clean it.

[0069] The cylinder 11 is provided with a feed inlet and a discharge outlet.

[0070] In a further embodiment, to facilitate checking the blockage of the filter screen 2, the water receiving tray 3 can also be made of transparent acrylic sheet.

[0071] In this embodiment, the spiral feed cylinder 1 is inclined to improve the water filtration effect.

[0072] It should be noted that when the screw feed cylinder 1 is set at an angle, the limiting post 42 can be tightly attached to the inner wall of the horizontal groove 62 under the action of gravity, so as to further improve the stability of the assembly of the water receiving tray 3 and the screw feed cylinder 1.

[0073] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
