Technical Field

[0001] The invention relates to the technical field of non-woven fabric squeezing, in particular to a non-woven fabric squeezing machine. Background Art

[0002] The emulsion flat bed filter of the acid rolling unit uses non-woven fabric to filter the emulsion. After use, the surface of the non-woven fabric contains a large amount of miscellaneous oil and sludge. These used filter cloths are directly collected in ton bags and sent to the incinerator for incineration. During the whole process, the filter cloth contains a large amount of sludge, which will cause environmental pollution and the sludge is also easily ignited by fire.

[0003] The degreasing and sludge removal of non-woven fabrics after use is very important for improving the on-site environment, preventing fire, reducing the weight of hazardous waste and reducing the labor intensity of operators. Therefore, a non-woven fabric squeezer is designed to realize the extrusion, oil removal and packaging of non-woven fabric briquetting.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a non-woven fabric squeezing machine, which can not only quickly squeeze out a large amount of oil sludge contained in the non-woven fabric, but also extrude and briquette the non-woven fabric for easy packaging.

[0006] In order to solve the above problems, the technical solution of the present invention is: a non-woven fabric squeezing machine, including a machine base, an extrusion chamber assembly is provided at the upper end of the machine base, an extrusion device is provided at one end of the extrusion chamber assembly, a drop hopper is provided at the upper end of the extrusion chamber assembly, a compression chamber assembly is provided at one end of the extrusion chamber assembly, an ejection device is provided at one end of the compression chamber assembly, and a door opening device is provided at the other end.

[0010] Furthermore, a hydraulic station and an electric control box are provided at the upper end of the machine base. The hydraulic station provides hydraulic power for the extrusion device, the door opening device and the ejection device, and the electric control box is used to control the operation of the squeezer system.

[0013] Furthermore, the discharge port of the compression chamber assembly away from the ejection device is provided with a plastic bag.

[0014] The present application also includes a method for using a nonwoven fabric squeezing machine, comprising the following steps:

[0015] Step 1: The non-woven fabric after use on the flat bed filter is collected into a roll by the reel driven by the pneumatic motor. The non-woven fabric is cut open by a blade manually and then taken off the reel and thrown into the waste non-woven fabric collection drum. The non-woven fabric goes into the hopper along the collection drum. When the sensor detects that the material has entered and accumulated to a certain height, the squeezer starts;

[0016] Step 2: Once the hydraulic telescopic rod is started, the extrusion plate moves to push the non-woven fabric into the extrusion chamber assembly. The cutting shears cut off the non-woven fabric that is not squeezed. The extrusion plate pushes the non-woven fabric into the compression chamber assembly for compression. The extrusion plate moves forward to extrude the non-woven fabric. Repeat this process several times to push the non-woven fabric into the compression chamber and hold it there for a certain period of time to allow the oil sludge on the surface of the non-woven fabric to be squeezed out as much as possible.

[0017] Step 3: When the non-woven fabric is squeezed for the set time, the telescopic end of the hydraulic telescopic rod 3 drives the push plate to move, pushing the squeezed non-woven fabric to the discharge port, starting the door opening device, and the hydraulic telescopic rod 2 drives the baffle to move upward to open the discharge port. The hydraulic telescopic rod 3 and the push plate push the extruded non-woven fabric block out of the discharge port;

[0018] Step 4: Install a plastic bag on the discharge port of the compression chamber assembly away from the ejection device, and pack and bundle the compressed blocks to prevent the material from dispersing and the residual oil sludge from dripping. Finally, use a roller conveyor to transport the blocks to the ton bag for storage, completing the entire extrusion, oil drainage and packaging process.

[0019] The advantages of the present invention compared with the existing technology are:

[0020] (1) The nonwoven fabric of the present invention enters the hopper along the collecting cylinder. After the sensor detects that the material has entered and accumulated to a certain height, the squeezer starts. When the hydraulic telescopic rod is started, the extrusion plate is driven to move, and the non-woven fabric entering the extrusion chamber assembly is pushed. The cutting shears cut the non-woven fabric that is not included in the extrusion, and the extrusion plate pushes the non-woven fabric into the compression chamber assembly for extrusion and compression. The extrusion plate moves forward to extrude the non-woven fabric, and repeats several times to push the non-woven fabric into the compression chamber and maintain it for a certain time so that the oil sludge on the surface of the non-woven fabric can be squeezed out as much as possible. When the non-woven fabric is squeezed to the set time, the telescopic end of the hydraulic telescopic rod three drives the push plate to move, and pushes the extruded non-woven fabric to the discharge port, and starts the door opening device. The hydraulic telescopic rod two drives the baffle to move upward to open the discharge port. The hydraulic telescopic rod three and the push plate push the extruded non-woven fabric block out of the discharge port. The discharge port sleeve at one end of the compression chamber assembly away from the pushing device is installed with a plastic bag. The pressed blocks are packed and bundled to avoid material dispersion and prevent residual oil sludge from dripping. Finally, they are transported to ton bags for storage by rollers, completing the entire extrusion, oil discharge and packaging process. The packaged extruded blocks are easy to transport and do not pollute the on-site environment. BRIEF DESCRIPTION OF THE DRAWINGS
