Description

Technical Field

[0001] The present invention belongs to the technical field of activated carbon processing, and particularly relates to an extrusion molding device for processing activated carbon water purifying agents. Background Art

[0002] Activated carbon water purifying agent is a highly efficient water purification material, generally in the form of columnar particles. It has a large specific surface area, well-developed micropores, high mechanical strength, fast adsorption speed and high purification degree, and is widely used in various water purification fields. Activated carbon water purifying agents are usually prepared by an extrusion molding method. In the prior art, a conventional press is generally used to directly extrude the kneaded coal paste to produce activated carbon strips. Parameters such as the temperature of the coal paste, residual gas and pressure during the extrusion process will have a significant impact on the forming quality of the activated carbon water purifying agent particles.

[0003] Before the formal extrusion, a pre-pressing operation needs to be carried out on the coal paste. The pre-pressing is used to discharge the excess gas in the coal paste, so that the extruded activated carbon particles are more plump and uniform. In the pre-pressing process, it is difficult for the prior art to achieve the technical problem of both closing the equipment to prevent the coal paste from being extruded in advance and not closing the equipment to ensure that the residual gas can be discharged. Moreover, it is difficult for the prior art to keep the coal paste at a relatively balanced temperature during the extrusion process, the production process is relatively complex, and the product quality is difficult to guarantee.

[0004] The prior art lacks a molding device that can achieve efficient and reliable pre-pressing and exhaust and can perform constant-temperature extrusion on purified activated carbon. Summary of the Invention

[0005] The present invention overcomes the deficiencies of the prior art and provides an extrusion molding device for processing activated carbon water purifying agents. The device realizes the motion effect of rotational vibration by means of the waveform structure characteristics, so as to be able to perform efficient pre-pressing and exhaust on the activated carbon material automatically, and automatically realize closed extrusion through the power provided by the extrusion. It effectively solves the problem that it is difficult for the prior art to effectively pre-press and exhaust the activated carbon before extrusion. Automatic exhaust is achieved through the reaction force generated by the increase in air pressure, and the exhaust facility is reliably sealed by means of the extrusion power, which not only improves the pre-pressing effect, but also can prevent the upward leakage of the activated carbon during the extrusion process, and improves the extrusion quality.

[0006] The technical solution adopted by the present invention is as follows: This solution provides an extrusion molding device for processing activated carbon water purifying agents, including an extrusion table, a dual extrusion power mechanism, and a synchronous unsealing and switching extrusion mechanism. The dual extrusion power mechanism is arranged on the upper inner wall of the extrusion table, and the synchronous unsealing and switching extrusion mechanism is slidably clamped on the inner side wall of the extrusion table. The synchronous unsealing and switching extrusion mechanism includes an extrusion receiving cylinder and an unsealing and transformable extrusion disk. The extrusion receiving cylinder is slidably clamped on the inner side wall of the extrusion table, and the unsealing and transformable extrusion disk is helically clamped at the lower end of the extrusion receiving cylinder. The dual extrusion power mechanism includes a servo hydraulic cylinder, an airtight disk, and a pre-pressurization and exhaust device. The pre-pressurization and exhaust device is arranged on the upper inner wall of the extrusion table. The servo hydraulic cylinders are symmetrically distributed and fixed on the lower surface of the upper inner wall of the extrusion table.

The airtight disk is slidably sleeved on the outer wall of the pre-pressurization and exhaust device, and the airtight disk is arranged below the output end of the servo hydraulic cylinder.

[0007] Preferably, the upper wall of the unsealing and transformable extrusion disk is uniformly and arrayedly provided with extrusion holes through which the inner diameter of the extrusion holes is set to be larger at the top and smaller at the bottom.

When one of the unsealing control plates is close to the outer side wall of the unsealing and transformable extrusion disk, all the through holes and all the extrusion holes correspond one by one.

At this time, all the extrusion holes are in a closed state.

[0009] As a further preference of this solution, the pre-pressurization and exhaust device includes a pre-pressurization hydraulic rod, a vibration pre-pressurization motor, and a rotary vibration pre-pressurization rod.

The vibration engaging wheels are respectively rollingly engaged and arranged inside the corrugated ring groove. An internal gear is fixedly provided along the lower edge of the inner side wall of the preloading power sleeve. The preloading power gear is slidably arranged on the inner wall of the internal gear. The preloading power gear and the internal gear are meshed. A preloading plate is fixedly provided at the lower end of the rotary vibration preloading rod. The contour of the outer circumference of the preloading plate is the same as the contour of the inner circumference of the extrusion receiving cylinder. Inverted cone exhaust holes are arranged through the preloading plate in an array. Guide strips are symmetrically distributed and fixedly provided on the side wall of the rotary vibration preloading rod.

[0012] Preferably, an airtight disc is slidably sleeved on the outer circumference of the rotary vibration preloading rod. The inner side wall of the airtight disc is slidably clamped with the guide strips. Inverted cone plugging heads are fixedly provided along the lower wall of the airtight disc in an array.

The two unsealing switching electric push rods are reversely electrically connected, that is, when one unsealing switching electric push rod extends, the other unsealing switching electric push rod contracts.

[0015] Further, a receiving cylinder is slidably clamped on the inner bottom wall of the extrusion table. The receiving cylinder is arranged below the synchronous unsealing switching extrusion mechanism. A reversing switch is fixedly provided on the side wall of the extrusion table. The reversing switch is electrically connected with the unsealing switching electric push rod.

[0016] The beneficial effects achieved by the present invention with the above structure are as follows:

[0017] (1) The double extrusion power mechanism achieves the motion effect of rotational vibration by means of the waveform structure characteristics, so as to be able to perform automatic and efficient pre-pressurization and exhaust on the activated carbon material, and automatically achieve closed extrusion through the power provided by extrusion, effectively solving the problem that it is difficult to effectively pre-pressurize and exhaust the activated carbon before extrusion in the prior art;

[0018] (2) The synchronous unsealing and switching extrusion mechanism uses the extrusion channels arranged in an array and corresponding one by one to provide an extrusion platform for the activated carbon, and realizes the switching between the closed and open states by switching the staggered and overlapping states of the extrusion channels, avoiding the leakage of the activated carbon during pre-pressurization and improving the pre-pressurization efficiency;

[0019] (3) The double extrusion power mechanism and the synchronous unsealing and switching extrusion mechanism cooperate with each other, realize automatic exhaust through the reaction force generated by the increase in air pressure, and make the exhaust facility reliably sealed by means of the extrusion power, not only improving the pre-pressurization effect, but also preventing the upward leakage of the activated carbon during the extrusion process and improving the extrusion quality;

[0020] (4) The unsealing transformation control part realizes the switching of the unsealing state of the unsealing transformation type extrusion disc by means of the bidirectional driving force provided by the unsealing switching electric push rod;

[0021] (5) The waveform ring groove provided by the vibration pre-pressurization power column guides the movement of the rotary vibration pre-pressurization rod. During the rotation of the rotary vibration pre-pressurization rod, the waveform ring groove causes the rotary vibration pre-pressurization rod to generate up and down vibrations. The rotary vibration pre-pressurization method of the pre-pressurization disc can significantly improve the pre-pressurization efficiency and prevent the activated carbon from sticking to the pre-pressurization disc;

[0022] (6) The pre-pressurization disc and the airtight disc cooperate with each other to realize the switching of the unsealing state of the pre-pressurization disc by the sealing and loosening of the inverted cone plugging head and the inverted cone exhaust hole. During pre-pressurization, the airtight disc automatically loosens under the action of air pressure to exhaust. During the formal extrusion, the airtight disc is pressed against the pre-pressurization disc under the extrusion force, so as to seal the pre-pressurization disc and prevent the activated carbon from extruding upward;

[0023] (7) The unsealing switching electric push rod realizes the rapid switching of the opening and closing states of the synchronous unsealing and switching extrusion mechanism through a special electrical connection method;

[0024] (8) The heating coil provides a constant-temperature extrusion environment for the extrusion accommodating cylinder, ensuring the reliability of extrusion and the reliability of the quality of the activated carbon finished product. BRIEF DESCRIPTION OF THE DRAWINGS

When the other unsealing control plate 3232 is close to the outer side wall of the unsealing and transformable extrusion disk 32, all the through holes 3233 and all the extrusion holes 321 are simultaneously staggered. At this time, all the extrusion holes 321 are in a closed state.

[0045] AsFigures 1 - 8 As shown in the figure, the preloading and exhaust device 23 includes a preloading hydraulic rod 231, a vibration preloading motor 232, and a rotating vibration preloading rod 233. The preloading hydraulic rod 231 is fixedly arranged on the inner upper wall of the extrusion table 1 and is vertically disposed.

[0046] As Figures 6 - 8 shown in the figure, a vibration preloading power column 2311 is fixedly arranged at the lower end of the output end of the preloading hydraulic rod 231. A corrugated ring groove 2312 is wound around the outer circumference of the vibration preloading power column 2311. The corrugated ring groove 2312 includes a wave crest groove 2313 and a wave trough groove 2314. The wave crest grooves 2313 and the wave trough grooves 2314 are alternately distributed in a circular array in sequence and are smoothly connected. The vibration preloading motor 232 is embedded in the lower wall of the vibration preloading power column 2311, and a preloading power gear 2321 is coaxially fixedly connected to the output end of the vibration preloading motor 232.

[0047] As Figures 1 - 10 shown in the figure, a preloading power sleeve 2331 is fixedly arranged at the upper end of the rotating vibration preloading rod 233. The preloading power sleeve 2331 is sleeved on the outer wall of the vibration preloading power column 2311. Vibration engaging wheels 2332 are rotatably arranged in a circular array along the inner circumference of the preloading power sleeve 2331. The array angle of the vibration engaging wheels 2332 is the same as the array angle of the wave crest grooves 2313. The vibration engaging wheels 2332 are respectively rollingly engaged and arranged inside the corrugated ring groove 2312. An internal gear 2333 is fixedly arranged along the lower edge of the inner side wall of the preloading power sleeve 2331. The preloading power gear 2321 is slidably arranged on the inner wall of the internal gear 2333. The preloading power gear 2321 and the internal gear 2333 are meshed. A preloading disc 2334 is fixedly arranged at the lower end of the rotating vibration preloading rod 233. The outer circumference profile of the preloading disc 2334 is the same as the inner circumference profile of the extrusion receiving cylinder 31. Inverted cone exhaust holes 2335 are arranged in a circular array through the preloading disc 2334. Guide bars 2336 are symmetrically distributed and fixedly arranged on the side wall of the rotating vibration preloading rod 233.

[0048] As Figures 1 - 11 shown in the figure, an airtight disc 22 is slidably sleeved on the outer circumference of the rotating vibration preloading rod 233. The inner side wall of the airtight disc 22 is slidably clamped with the guide bars 2336. Inverted cone plugging heads 221 are fixedly arranged in a circular array on the lower wall of the airtight disc 22. The inverted cone plugging heads 221 and the inverted cone exhaust holes 2335 are arranged in one-to-one correspondence.

[0049] As Figures 1 - 12As shown in the figure, an external thread ring 311 is fixedly provided at the lower edge of the circumferential outer wall of the extrusion receiving cylinder 31. The unsealing transformation type extrusion disc 32 is arranged at the lower end of the extrusion receiving cylinder 31 through the spiral engagement of the internal thread ring 322 and the external thread ring 311. A heating coil 312 is fixedly provided inside the circumferential side wall of the extrusion receiving cylinder 31.

[0050] As Figures 1 - 13 shown in the figure, unsealing switching electric push rods 11 are symmetrically and fixedly arranged on the inner side wall of the extrusion table 1. The output ends of the unsealing switching electric push rods 11 are respectively arranged outside the unsealing control board 3232. The two unsealing switching electric push rods 11 are reversely electrically connected, that is, when one unsealing switching electric push rod 11 extends, the other unsealing switching electric push rod 11 contracts.

[0051] As Figures 1 - 13 shown in the figure, a receiving cylinder 12 is slidably clamped on the inner bottom wall of the extrusion table 1. The receiving cylinder 12 is arranged below the synchronous unsealing switching extrusion mechanism 3. A commutation switch 13 is fixedly provided on the side wall of the extrusion table 1. The commutation switch 13 is electrically connected to the unsealing switching electric push rod 11.

[0052] In the specific implementation of this embodiment, first, it is necessary to prepare materials, load materials and adjust the equipment in place. The operator connects and fixes the unsealing transformation type extrusion disc 32 and the extrusion receiving cylinder 31, and places the kneaded activated carbon into the extrusion receiving cylinder 31. Adjust the position of the extrusion receiving cylinder 31 so that the extrusion receiving cylinder 31 is exactly below the pre-pressing disc 2334. Then place the receiving cylinder 12 below the extrusion receiving cylinder 31. In the initial state, the unsealing transformation control member 323 biases towards one side of the unsealing transformation type extrusion disc 32. All the through holes 3233 and all the extrusion holes 321 are staggered at the same time, and all the extrusion holes 321 are in a closed state, that is, the unsealing transformation type extrusion disc 32 is in a closed state. The pre-pressing hydraulic rod 231 and the servo hydraulic cylinder 21 are in a contracted state. The airtight disc 22 is stably placed on the upper wall of the pre-pressing disc 2334 under the action of gravity. At this time, the inverted cone plug 221 is respectively inserted into the inverted cone exhaust hole 2335 and closes the inverted cone exhaust hole 2335.

[0053] When starting the extrusion operation, the operator activates the preloading hydraulic rod 231 and the vibrating preloading motor 232. The preloading hydraulic rod 231 extends and drives the preloading disc 2334 to move downward until it enters the inner wall of the extrusion receiving cylinder 31. The vibrating preloading motor 232 drives the preloading power gear 2321 to rotate. The preloading power gear 2321 drives the preloading power sleeve 2331 to rotate through the internal gear 2333, so that the entire rotating vibrating preloading rod 233 rotates around the axis of the vibrating preloading power column 2311. During this rotation process, the vibrating engagement wheel 2332 is guided by the waveform annular groove 2312, thus generating a movement effect of vibrating up and down while surrounding the vibrating preloading power column 2311. That is, the preloading disc 2334 shows a movement effect of continuously rotating and descending on the inner wall of the extrusion receiving cylinder 31 and vibrating continuously in the vertical direction. During the descent of the preloading disc 2334, the residual gas above the interior of the extrusion receiving cylinder 31 increases in pressure due to the reduced space, causing the airtight disc 22 to loosen. The residual gas is discharged from the equipment through the inverted cone exhaust hole 2335. As the preloading disc 2334 continuously descends and rotates vibrates, the activated carbon material inside the extrusion receiving cylinder 31 is gradually compacted.

[0054] After preloading is completed, the operator presses the reversing switch 13, and the two unsealing switching electric push rods 11 start to operate. One of the unsealing switching electric push rods 11 extends, and the other unsealing switching electric push rod 11 contracts. The extending unsealing switching electric push rod 11 gradually approaches and pushes the unsealing control plate 3232 it contacts, causing the entire unsealing transformation control member 323 to slide until the unsealing control plate 3232 closely adheres to the outer wall of the unsealing transformation type extrusion disc 32. All the through holes 3233 and all the extrusion holes 321 are in one-to-one correspondence. At this time, all the extrusion holes 321 are in a through state, enabling the activated carbon water purifier to be smoothly extruded. After the state of the unsealing transformation type extrusion disc 32 is switched, the servo hydraulic cylinder 21 starts to extend synchronously. The preloading hydraulic rod 231 is powered off and in a free telescopic state, and the vibrating preloading motor 232 is powered off. When the lower wall of the output end of the servo hydraulic cylinder 21 contacts the upper wall of the airtight disc 22, the servo hydraulic cylinder 21 starts the activated carbon extrusion operation. The airtight disc 22 and the preloading disc 2334 are closely attached under the thrust of the servo hydraulic cylinder 21 and the reaction of the activated carbon material inside the extrusion receiving cylinder 31. The inverted cone exhaust hole 2335 is in a closed state. The activated carbon material is gradually extruded through the extrusion holes 321 under the extrusion force provided by the servo hydraulic cylinder 21 and falls into the receiving cylinder 12, thus achieving efficient extrusion. During the extrusion process, the heating coil 312 always remains powered on, providing a constant-temperature extrusion environment for the extrusion receiving cylinder 31, ensuring the reliability of extrusion and the balance of the finished product quality.

[0055] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0056] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
