Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a single-shaft screw press. Background Technology

[0002] A press is a mechanical device that separates liquids from solids in materials by applying physical pressure. Its core function is to separate liquids (such as juice, oil, and water) from solid substances through squeezing and compression. It is widely used in food processing, industrial production, agriculture, and environmental protection.

[0003] During use, the press can effectively separate the liquid from the material. However, when dealing with materials with a large amount of plant fiber, such as coconut shells, the pressure generated by the extrusion is different, and the separation effect varies depending on the moisture content of the material. As a result, the press has a poor pressing effect when dealing with high-fiber materials. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when dealing with materials with a large amount of plant fiber such as coconut shells, the pressure generated by extrusion varies, and the separation effect of materials with different moisture content is also different, resulting in poor pressing effect of the press when dealing with high fiber materials.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a single-shaft screw press, including a mounting frame, an input chamber and a filter chamber fixedly connected to the top of the mounting frame, a drive mechanism provided on the side of the top of the mounting frame, a conveying screw fixedly connected to the output end of the drive mechanism, the conveying screw being located inside the filter chamber, an output hopper fixedly connected to the output end of the filter chamber, a mounting plate rotatably connected to the top of the output hopper, an electric push rod installed in the middle of the mounting plate, a blocking disc rotatably connected to the output end of the electric push rod, a connecting frame installed on the side of the filter chamber, and the blocking disc rotatably connected to the connecting frame. After pressing the material, the material is output through the output hopper. By setting the electric push rod to adjust the angle of the blocking disc, the space between the material output port and the blocking disc is controlled. By limiting the flow area of ​​the material outlet through the blocking disc 13, the reverse resistance in the pressing zone is increased. This resistance forces the material to stay in the pressing section for a longer time, thereby increasing the squeezing pressure, promoting the full separation of liquid, and increasing the liquid yield.

[0006] In a preferred embodiment, the drive mechanism includes a drive motor and a gearbox and gear set fixedly connected to the mounting bracket. The output end of the drive motor is mounted on the gearbox, the output end of the gearbox is connected to the gear set for transmission, and the output end of the gear set is fixedly connected to the conveying screw. The gearbox, gear set, and drive motor are configured as the power output mechanism of the device.

[0007] In a preferred embodiment, a filter screen is fixedly connected around the conveying screw inside the filter chamber, and a collection chamber is fixedly connected at the bottom of the input chamber and the filter chamber. The filter screen prevents solid materials from falling out during the pressing process, and the collection chamber collects the pressed liquid.

[0008] In a preferred embodiment, the collection bin is hopper-shaped and has an output interface installed at the bottom. The liquid that has been pressed out can be collected through the collection bin and then output through the output interface.

[0009] In a preferred embodiment, an installation box is fixedly connected to the side wall of the input compartment, and a buffer frame is rotatably connected inside the installation box. By setting the buffer frame, the falling material can be buffered to prevent the large gravity of the falling material from damaging the conveying screw.

[0010] In a preferred embodiment, fixing pads are fixedly connected to the four corners of the bottom of the mounting bracket. The fixing pads have pre-drilled fixing holes at the four corners, which can be used to firmly fix the device. The installation convenience of the device is improved by setting fixing pads.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model, by setting an adjustable blocking plate, restricts the flow area of ​​the material outlet and increases the reverse resistance in the pressing zone. This resistance forces the material to stay in the pressing section for a longer time, thereby increasing the squeezing pressure, promoting the full separation of liquid, and improving the liquid yield.

[0013] 2. This utility model, by setting a buffer frame, can buffer the falling materials and prevent the large gravity of the falling materials from damaging the conveying screw. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a single-shaft screw press, including a mounting frame 1. An input chamber 5 and a filter chamber 3 are fixedly connected to the top of the mounting frame 1. A drive mechanism is provided on the side of the top of the mounting frame 1. A conveying screw 10 is fixedly connected to the output end of the drive mechanism. The conveying screw 10 is located inside the filter chamber 3. An output hopper 4 is fixedly connected to the output end of the filter chamber 3. A mounting plate 11 is rotatably connected to the top of the output hopper 4. An electric push rod 12 is installed in the middle of the mounting plate 11. A blocking disc 13 is rotatably connected to the output end of the electric push rod 12. A connecting plate is installed on the side of the filter chamber 3. The connecting frame 14 and the blocking plate 13 are rotatably connected to the connecting frame 14. After the device presses the material, it will output it through the output hopper 4. The angle of the blocking plate 13 is adjusted by setting the electric push rod 12, thereby controlling the space between the material output port and the blocking plate 13. By adjusting the space between the output port and the blocking plate 13, the flow area of ​​the material outlet is limited. The blocking plate 13 increases the reverse resistance in the pressing zone. This resistance forces the material to stay in the pressing section for a longer time, thereby increasing the squeezing pressure, promoting the full separation of liquid, and increasing the liquid output rate.

[0022] like Figure 1-4 As shown, the drive mechanism includes a drive motor 8 and a gearbox 7 and a gearbox 6 fixedly connected to the mounting bracket 1. The output end of the drive motor 8 is mounted on the gearbox 7, the output end of the gearbox 7 is connected to the gearbox 6, and the output end of the gearbox 6 is fixedly connected to the conveying screw 10. The gearbox 6, gearbox 7, and drive motor 8 are set as the power output mechanism of the device.

[0023] like Figure 1-4 As shown, a filter screen 9 is fixedly connected around the conveying screw 10 inside the filter chamber 3. A collection chamber 2 is fixedly connected at the bottom of the input chamber 5 and the filter chamber 3. The filter screen 9 prevents solid materials from falling out during the pressing process, and the collection chamber 2 is set up to collect the pressed liquid.

[0024] like Figure 1-4 As shown, the collection chamber 2 is bucket-shaped and has an output interface installed at the bottom. The liquid that has been pressed out can be collected through the collection chamber 2 and output through the output interface.

[0025] like Figure 1-4 As shown, a mounting box 17 is fixedly connected to the side wall of the input chamber 5. A buffer frame 15 is rotatably connected inside the mounting box 17. A buffer damping is provided at the connection between the buffer frame 15 and the mounting box 17. When the material enters, the buffer frame 15 is squeezed and the angle changes. During this process, the material's weight is offset. After the material leaves, the buffer frame will automatically reset because the weight of the rear end of the buffer frame is greater than the contact end. By setting the buffer frame, the service life of the buffer frame can be improved. The buffer frame 15 can buffer the falling material and prevent the material from causing damage to the conveying screw 10 due to the large gravity when it falls.

[0026] like Figure 1-4 As shown, fixing pads 16 are fixedly connected to the four corners of the bottom of the mounting bracket 1. Fixing pads 16 have pre-drilled fixing holes at the four corners, which can be used to firmly fix the device. The installation convenience of the device is improved by setting fixing pads 16.

[0027] Working principle: When adjusting the angle of the blocking plate 13, by controlling the output length of the electric push rod 12 and cooperating with the limit of the mounting frame 14, the angle of the blocking plate 13 around the mounting frame 14 can be changed, thereby changing the size of the space between the material outlet and the blocking plate 13. By adjusting the size of the space between the outlet and the blocking plate 13, the device can freely adjust and limit the flow area of ​​the material outlet, making the device more flexible in use.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
