DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a hydraulic pressing device, such as Figure 1-Figure 3 As shown, it includes a box body 1, a front hydraulic cylinder 2 is installed on the outside of one end of the box body 1, a rear hydraulic cylinder 3 is installed on the outside of the other end of the box body 1, a feeding port 13 is arranged on the top of the box body 1, a cover plate 4 is installed above the feeding port 13, a support plate 6 is installed on one side of the lower part of the box body 1, a motor 5 and an oil pump 7 are installed on the support plate 6, a turntable 51 is installed on the output shaft of the motor 5, and a discharge opening and closing component 8 is connected to one side of the turntable 51 deviating from the center of the circle, a juice discharge port 11 and a slag discharge port 12 are arranged at the bottom of the box body 1, and the discharge opening and closing component 8 is driven by the motor 5 to move horizontally, thereby opening and closing the slag discharge port 12, and the arrangement of the front hydraulic cylinder 2 and the rear hydraulic cylinder 3 provides a uniform and powerful squeezing force, ensuring efficient solid-liquid separation. The design of the feeding port 13 makes it simple and convenient to put materials in, and at the same time, the cover plate 4 effectively prevents the material from splashing and external pollution.

[0021] It is particularly worth mentioning that the system realizes the automatic opening and closing function of the slag discharge port 12 through the turntable 51 driven by the motor 5 and the discharge opening and closing assembly 8. This design not only improves the operating efficiency, but also greatly reduces the need for manual intervention, thereby saving labor costs and improving production safety. In addition, the automatic control of the slag discharge port also reduces material leakage and waste, making the entire pressing process more environmentally friendly and economical.

[0022] In this embodiment, two push plates are arranged inside the box body 1, and the two push plates are respectively connected to the output shafts of the front hydraulic cylinder 2 and the rear hydraulic cylinder 3, so as to facilitate bidirectional synchronous squeezing operation.

[0023] Specifically, the cover plate 4 is fixed to the top opening of the box body 1 by means of screws, so as to cover the top during squeezing and ensure that the internal pressure of the box body 1 is sufficient.

[0024] Furthermore, a plurality of legs 14 are installed at the bottom of the box body 1 to facilitate stable support of the box body 1 .

[0025] Furthermore, the output end of the oil pump 7 is connected to the input ports of the front hydraulic cylinder 2 and the rear hydraulic cylinder 3 respectively through two pipelines, the input end of the oil pump 7 is connected to the oil inlet pipeline, and the two output end pipelines of the oil pump 7 are controlled by the solenoid valve 71, which is convenient for adjusting the different left and right pressing actions according to needs.

[0026] Furthermore, the discharge opening and closing assembly 8 includes a connecting rod 81, one end of the connecting rod 81 is rotatably connected to one side of the turntable 51 at a position deviating from the center of the circle, and the other end of the connecting rod 81 is rotatably connected to a horizontal movable plate 82, and a guide sleeve 83 is provided on the horizontal movable plate 82. The horizontal movable plate 82 is slidably connected to the guide sleeve 83, and the guide sleeve 83 is welded and fixed to the bottom of the box body 1. The slag discharge port 12 is opened and closed by the movement of the horizontal movable plate 82, thereby realizing the switching operation of pressing and slag discharge.

[0027] Furthermore, a sealing block 821 is installed on the top of the horizontal movable plate 82 near the slag discharge port 12. The top of the sealing block 821 is an upwardly protruding arc structure, which is used to improve the sealing effect of the slag discharge port 12. The sealing block 821 is made of sponge material and can be deformed to seal the slag discharge port 12.

[0028] When the hydraulic pressing equipment of the utility model is in use, first, the operator puts the material to be pressed into the box body 1 through the feeding port 13, then covers the cover plate 4 and fixes it to the top of the box body 1 through screws to ensure the sealing and pressure stability during the pressing process.

[0029] Next, the operator starts the oil pump 7 and controls the output of the oil pump 7 through the solenoid valve 71 to provide hydraulic oil to the front hydraulic cylinder 2 and the rear hydraulic cylinder 3. Driven by the hydraulic oil, the output shafts of the front hydraulic cylinder 2 and the rear hydraulic cylinder 3 begin to move, driving the push plates connected thereto to perform bidirectional synchronous squeezing of the material.

[0030] During the squeezing process, the material in the box body 1 is subjected to uniform and strong squeezing force, thereby achieving efficient solid-liquid separation. The separated liquid is discharged through the juice outlet 11, while the solid residue remains in the box body 1.

[0031] When the pressing is completed, the operator starts the motor 5, and the output shaft of the motor 5 drives the turntable 51 to rotate. Since the connecting rod 81 of the discharge opening and closing assembly 8 is connected to one side of the turntable 51 at a position deviating from the center of the circle, the rotation of the turntable 51 drives the connecting rod 81 to move horizontally. The other end of the connecting rod 81 is connected to the horizontal movable plate 82, so the horizontal movable plate 82 slides horizontally under the guidance of the guide sleeve 83, thereby opening or closing the slag discharge port 12.

[0032] When the slag discharge port 12 is opened, the solid residue after squeezing will be discharged from the slag discharge port 12. After the slag discharge is completed, the motor 5 is reversed to return the rotary disc 51 to the initial position, and the slag discharge port 12 is closed again to prepare for the next round of squeezing.

[0033] During the whole process, the oil pump 7, the solenoid valve 71 and the motor 5 are precisely controlled by the automatic control system, so that the automatic operation of squeezing, juice discharge and slag discharge is realized, which greatly improves the production efficiency and the convenience of operation.

[0034] Finally, it should be noted that the front hydraulic cylinder 2, the rear hydraulic cylinder 3, etc. in this embodiment, the electronic components in the above parts are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above electrical components are connected by wires respectively.
