Description

Technical Field

[0001] The utility model relates to the technical field of waste paper processing equipment, in particular to a full-electric dust compression device and a dust cake press. Background Art

[0002] A large amount of dust and waste paper scraps will be generated in the process of waste paper recycling. In order to prevent these dust and waste paper scraps from floating in the air and polluting the air, dust removal equipment is usually used to collect the dust and waste paper scraps. The current collection method is bag storage. The cost of using tailing bags is too high, and the collection of tailings and the replacement of collection bags are too dusty. There is too much dust in the transportation and on-site operation environment, and the environmental cleanliness is low.

[0003] A Chinese patent with publication number CN117484941A discloses an automatic briquetting machine for paper medium tailings, and records that the extrusion device includes a mounting seat, a pushing hydraulic cylinder, a briquetting cavity, a discharge pipe and a clamping hydraulic cylinder, the mounting seat is provided with the pushing hydraulic cylinder, the briquetting cavity, the discharge pipe and the clamping hydraulic cylinder, the top of the briquetting cavity is provided with a feed inlet, the clamping hydraulic cylinder is arranged above the discharge pipe, and the side of the discharge pipe is provided with an extrusion seam so as to squeeze the paper medium tailings in the discharge pipe downwardly through the clamping hydraulic cylinder, the pushing hydraulic cylinder, the briquetting cavity and the discharge pipe are connected in sequence so as to push the paper medium tailings in the briquetting cavity and the discharge pipe out of the discharge pipe in sequence through the pushing hydraulic cylinder, and the pushing hydraulic cylinder and the clamping hydraulic cylinder are both connected to the control system.

[0004] In the above scheme, a pusher hydraulic cylinder is used to compress dust and waste paper. As a result, the pressure and compression stroke of each compression are fixed by the cylinder itself. It cannot be adjusted according to the actual situation. At the same time, the hydraulic cylinder must use hydraulic oil, so there is a risk of oil leakage and contamination during use. Utility Model Content

Detailed Description of the Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figure 1-2As shown in the figure, the all-electric dust compression device of the present utility model includes a connecting seat 01 fixedly installed on an external frame. The bottom of the connecting seat 01 is fixedly connected by welding with a horizontally arranged compression pipe 02. An inlet channel 19 communicating with the compression pipe 02 is provided in the connecting seat 01. A telescopic joint 03 is provided at one end of the compression pipe 02. Two compression plates 04 are symmetrically arranged on the compression pipe 02. A connecting rod 05 is provided between the two compression plates 04. The connecting rod 05 is preferably a screw rod. By screwing a nut on the connecting rod 05, the two compression plates 04 are made to approach each other to apply a compression force to the end of the compression pipe 02, causing the telescopic joint 03 to contract, so that the end of the compression pipe 02 becomes conical. Similarly, other existing technologies such as a hydraulic pump can be used to act on the compression pipe 02 to cause the telescopic joint 03 to contract, so that the end of the compression pipe 02 becomes conical.

[0025] On one side of the compression pipe 02, an extrusion component is coaxially arranged. Dust enters the compression pipe 02 through the inlet channel 19. The end of the compression pipe 02 is conical under the action of the two compression plates 04. Then, the extrusion component extrudes the dust located in the compression pipe 02 into a dust cake of a certain shape. This facilitates subsequent transportation and treatment. Since the dust is compressed into a dust cake, the pollution of the air by the dust is avoided.

[0026] Please refer to Figure 2 As shown in the figure, the extrusion component includes an extrusion seat 06 fixedly installed on the compression pipe 02 by fasteners. The extrusion seat 06 is coaxially arranged with the compression pipe 02. A driving shaft 07 is rotatably installed in the extrusion seat 06 through a bearing, and an extrusion shaft 08 is slidably installed. The extrusion shaft 08 is threadedly connected with the driving shaft 07, and one end of the extrusion shaft 08 extends into the compression pipe 02. When the driving shaft 07 rotates, it drives the extrusion shaft 08 to reciprocate along the axis of the compression pipe 02 in the extrusion seat 06. For example, when the driving shaft 07 rotates clockwise, it drives the extrusion shaft 08 to move towards the end (telescopic joint 03) of the compression pipe 02 to compress the dust in the compression pipe 02. On the contrary, when the driving shaft 07 rotates counterclockwise, it drives the extrusion shaft 08 to move away from the compression pipe 02, so that the dust enters the compression pipe 02 from the inlet channel 19 for the next compression.

[0027] The extrusion seat 06 includes an installation pipe 09 fixedly installed on the frame by fasteners. A connecting pipe 10 is provided between the installation pipe 09 and the compression pipe 02. The extrusion shaft 08 is slidably arranged in the connecting pipe 10. The driving shaft 07 is rotatably installed in the installation pipe 09 through a bearing. One end of the driving shaft 07 extends into the connecting pipe 10 and is threadedly connected with the extrusion shaft 08. The other end of the driving shaft 07 extends outside the installation pipe 09 and is fixedly connected with a driving source. When the driving source works, it drives the driving shaft 07 to rotate in the installation pipe 09, and the rotation of the driving shaft 07 drives the extrusion shaft 08 to reciprocate along the axis of the compression pipe 02 in the connecting pipe 10.

[0028] The drive source described in this application includes a driven wheel 13 fixedly installed on the drive shaft 07 and a second reduction motor 11 installed on the mounting frame. The output end of the second reduction motor 11 is fixedly installed with a driving wheel 12, and the transmission ratio of the driving wheel 12 to the driven wheel 13 is greater than 1. The driving wheel 12 and the driven wheel 13 are in transmission connection, so that the output torque of the second reduction motor 11 is further amplified through the cooperation of the driving wheel 12 and the driven wheel 13, making the dust more compact during the compression process. Similarly, other existing technologies can be used to act on the drive shaft 07 to make it rotate in the installation pipe 09.

[0029] In order to enable the extrusion shaft 08 to reciprocate along the axis of the compression pipe 02 in the connecting pipe 10, a guide block 14 is fixedly installed on the outer surface of the extrusion shaft 08, and a guide groove 15 adapted to the guide block 14 is provided on the connecting pipe 10. The guide block 14 is inserted into the guide groove 15. When the drive shaft 07 rotates, the extrusion shaft 08 reciprocates linearly in the connecting pipe 10 through the cooperation of the guide groove 15 and the guide block 14.

[0030] One end of the extrusion shaft 08 is provided with a top head 16 adapted to the compression pipe 02, and the top head 16 is located inside the compression pipe 02. An internal thread 17 is provided inside the extrusion shaft 08. An external thread 18 adapted to the internal thread 17 is provided on the drive shaft 07, and the internal thread 17 is a trapezoidal thread. Through the cooperation of the external thread 18 and the internal thread 17, the rotation of the drive shaft 07 drives the extrusion shaft 08 to move in the connecting pipe 10. When the extrusion shaft 08 is moving, the extrusion shaft 08 reciprocates linearly in the connecting pipe 10 through the cooperation of the guide groove 15 and the guide block 14.

[0031] A powdering rack 20 is inclined in the feeding channel 19. The powdering rack 20 of this application is U-shaped. A first motor 21 is fixedly installed outside the connecting seat 01, and the output end of the first motor 21 is fixedly connected to the powdering rack 20, so that the powdering rack 20 rotates in the feeding channel 19. When the dust accumulates on the upper edge of the connecting seat 01, due to the small size and mutual adhesion of the dust particles, a tight accumulation is formed. The gaps between these particles are small and interlock with each other, forming a cavity gap similar to an arch bridge. This structure increases the internal friction and support force, so that the dust cannot fall into the feeding channel 19. Therefore, the powdering rack 20 is rotatably arranged in the feeding channel 19 and is inclined in the feeding channel 19, so that when the powdering rack 20 rotates, the outer edge of the powdering rack 20 is higher than the upper edge of the connecting seat 01, destroying the cavity gap of the arch bridge formed by several dust combinations, so that the dust can smoothly fall into the feeding channel 19 and enter the compression pipe 02 for extrusion.

[0032] Please refer to Figure 3-4As shown in the figure, the present application also provides a dust briquetting machine for compressing the dust collected by an external dust removal device. It includes a frame, on which a storage bucket 22 is fixedly installed by means of fasteners or welding, and the above-mentioned all-electric dust compression device is arranged directly below the storage bucket 22. A transition port 23 communicating with the above-mentioned all-electric dust compression device is arranged at the bottom of the storage bucket 22, and the transition port 23 is connected to the feed channel 19 of the all-electric dust compression device in a through manner. When the dust collected by the external dust removal device falls into the storage bucket 22, it enters the all-electric dust compression device through the transition port 23, and the all-electric dust compression device compresses the dust into a powder cake, which is convenient for subsequent movement and processing.

[0033] A cover 24 is fixedly installed at the top of the storage bucket 22 by means of fasteners. A connection port 25 is arranged in the middle of the cover 24. The external dust removal device is directly connected or connected through a pipeline to the connection port 25. When the external dust removal device is working, the dust it collects enters the storage bucket 22 through the connection port 25.

[0034] After the dust falls into the storage bucket 22, the dust will accumulate at the bottom of the storage bucket 22. In order to enable the dust accumulated at the bottom of the storage bucket 22 to smoothly enter the transition port 23 and then enter the compression device. A scraping component is arranged in the storage bucket 22, and a reduction motor 1 is fixedly installed in the frame by fastening. The output end of the reduction motor 1 passes through the bottom of the storage bucket 22 and is fixedly connected to the scraping component. After the reduction motor 1 is started, the scraping component rotates in the storage bucket 22. Similarly, any existing driving source such as a motor can be used to act on the scraping component to make it rotate in the storage bucket 22.

[0035] The scraping component includes a fixed shaft 26, and the fixed shaft 26 is fixedly connected to the output end of the reduction motor 1 by an interference fit. At least one scraping plate 27 is fixedly connected to the outer circumferential surface of the fixed shaft 26 by welding. In the present application, three scraping plates 27 are fixedly connected to the outer circumferential surface of the fixed shaft 26. The scraping plate 27 is arranged at an angle with the discharge bucket, and the bottom of the scraping plate 27 abuts against the bottom of the storage bucket 22. When the scraping component rotates in the storage bucket 22 under the action of the reduction motor 1, the scraping plate 27 pushes the dust located at the bottom of the storage bucket 22 into the transition port 23, so that the dust enters the compression device.

[0036] A sensor 28 is provided on the side wall of the storage bin 22, and the probe of the sensor 28 is located inside the storage bin 22. A control device is provided inside the frame. The sensor 28 is electrically connected to the control device. When the probe senses that there is dust in the storage bin 22, the control device controls the first reduction motor to start, so that the scraping assembly rotates inside the storage bin 22. It should be noted that the control device described here is a PLC (Programmable Logic Controller). Receiving the signal of the sensor 28 by the PLC and controlling the start and stop of the first reduction motor according to its signal belong to the prior art and will not be elaborated here.

[0037] When the dust press of the present application is in use, the dust collected by the external dust removal equipment enters the storage bin 22. The scraping assembly of the storage bin 22 rotates inside the storage bin 22 under the action of the first reduction motor. When the scraping assembly rotates, it pushes the dust in the storage bin 22 towards the transition port 23, and the dust falls into the all-electric dust compression device through the transition port 23, and the dust is compressed into a dust cake.

[0038] If there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0039] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
