Description

Technical Field

[0001] This utility model relates to the field of water-absorbing resin processing technology, specifically a drying and grinding integrated machine for superabsorbent polymer resin. Background Technology

[0002] Superabsorbent polymer (SAP) is a functional polymer material with a large number of hydrophilic groups. It has a high water absorption capacity, capable of absorbing hundreds to thousands of times its own weight in water, and excellent water retention properties. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even under pressure.

[0003] In the processing of water-absorbing resin, large pieces of wet resin are first crushed into small pieces <10mm by a coarse crusher (double roller or jaw crusher). Then, the small pieces of wet resin are dried. The dried resin is then ground by a grinding equipment. Designing an efficient and stable drying and grinding device is crucial to meet the drying and grinding requirements of water-absorbing resin. Utility Model Content

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.

[0030] Please see Figures 1-4In this embodiment of the present invention, a drying and grinding integrated machine for superabsorbent polymer resin includes a base assembly 1 consisting of a base 101, a support platform 102, support rollers 103, and a first drive motor 104. The support platform 102 is fixed to the top of the base 101. Four support rollers 103 are provided and are arranged in a matrix on the top of the support platform 102. The first drive motor 104 is mounted on one end of the support platform 102 through a bracket, and the output end of the first drive motor 104 is fixedly connected to the rotating shaft of one support roller 103. A drying assembly 2 is installed on the top of the support platform 102 through the support rollers 103. The drying assembly 2 is used to dry the resin.

[0031] A grinding component 3 is provided at the top of the base 101, at the end of the support platform 102 away from the first drive motor 104. The grinding component 3 is used to grind the dried resin.

[0032] The drying assembly 2 includes a drying drum 201, a limiting ring seat 202, a central drying drum 203, a baffled drying drum 204, a fixed outer drum 206, and an electric heating coil 207;

[0033] The limiting ring seats 202 are symmetrically fixed at both ends of the outer wall of the drying drum 201, and the drying drum 201 is rotatably connected to the support roller 103 through the limiting ring seats 202. The fixed outer cylinder 206 is located in the middle of the two limiting ring seats 202 and wraps around the outside of the drying drum 201. The bottom of the fixed outer cylinder 206 is fixedly connected to the support platform 102. The electric heating coil 207 is installed inside the fixed outer cylinder 206 and distributed outside the drying drum 201. The electric heating coil 207 is powered on to heat the inside of the drying drum 201.

[0034] One end of the drying drum 201 is a sealed structure, and the other end is an open structure. The middle drying drum 203 is fixed in the middle of the sealed structure of the drying drum 201. One end of the middle drying drum 203 protrudes to the outside of the drying drum 201, and the other end of the middle drying drum 203 extends into the inside of the drying drum 201.

[0035] The baffled drying cylinder 204 is distributed between the inner side of the drying drum 201 and the outer side of the middle drying cylinder 203. The baffled drying cylinder 204 is fixedly connected to the inner wall of the drying drum 201 through a bracket. The end of the baffled drying cylinder 204 near the sealing structure of the drying drum 201 is open, and the end of the baffled drying cylinder 204 near the opening structure of the drying drum 201 is sealed.

[0036] The "S"-shaped channel, consisting of the central drying cylinder 203, the baffled drying cylinder 204, and the spiral guide plate 205, is used to increase the drying stroke of the resin.

[0037] Spiral guide plates 205 are welded and fixed inside the drying drum 201, the middle drying drum 203, and the baffle drying drum 204. The spiral directions of the spiral guide plates 205 inside the drying drum 201 and the middle drying drum 203 are the same, while the spiral direction of the spiral guide plates 205 inside the baffle drying drum 204 is opposite to that of the spiral guide plates 205 inside the drying drum 201 and the middle drying drum 203.

[0038] Ventilation holes are provided in the middle drying cylinder 203 located inside the drying rotary cylinder 201 and in the entire baffled drying cylinder 204.

[0039] In this embodiment, the operating principle of this device is as follows:

[0040] After coarse crushing, the small wet resin particles are conveyed to the interior of the central drying cylinder 203 by an external conveying device. During this process, the first drive motor 104 is started simultaneously. The drive motor 104 drives a support roller 103 to rotate. This support roller 103 drives the limiting ring seat 202 and the drying drum 201 to rotate through friction (the other three support rollers 103 rotate passively). The drying drum 201 drives the central drying cylinder 203 and the baffled drying cylinder 204 to rotate synchronously.

[0041] At this time, the spiral guide plate 205 inside the middle drying cylinder 203 can transport the resin in the middle drying cylinder 203 to the rear direction. Finally, the resin inside the middle drying cylinder 203 falls into the baffle drying cylinder 204, and the spiral guide plate 205 inside the baffle drying cylinder 204 transports the resin to the sealed end of the drying drum 201. Finally, the resin inside the baffle drying cylinder 204 falls into the drying drum 201, and the spiral guide plate 205 inside the drying drum 201 transports the resin to the open end. In this way, the resin can be transported in an "S" shaped trajectory.

[0042] By coordinating the above-mentioned components, the resin conveying stroke can be effectively extended. At the same time, the power supply of the electric heating coil 207 is simultaneously turned on, so that the electric heating coil 207 runs to heat the inside of the drying cylinder, thereby realizing the resin drying operation (it should be noted that the ventilation holes on the middle drying cylinder 203 and the baffle drying cylinder 204 are used to ensure air flow). By extending the resin conveying stroke, the resin drying effect can be effectively guaranteed. At the same time, the overall length of the drying assembly 2 can be shortened, thereby effectively reducing the space occupied by the equipment.

[0043] Please refer to this carefully. Figures 1-4 The grinding assembly 3 includes a mounting platform 301, a collecting ring seat 302, a fixed grinding table 303, a top plate 304, a discharge plate 305, a second drive motor 306, and a conical grinding roller 307.

[0044] The collecting ring seat 302 is installed on the outer side of the top of the mounting platform 301. The collecting ring seat 302, the fixed grinding table 303, and the top plate 304 are installed and fixed in sequence from bottom to top. The discharge plate 305 is fixed to one side of the outer wall of the collecting ring seat 302 and communicates with the inner cavity of the collecting ring seat 302.

[0045] The second drive motor 306 is installed inside the mounting platform 301. The output end of the second drive motor 306 passes through the mounting platform 301 and extends into the fixed grinding table 303 and is fixedly connected to the conical grinding roller 307. The rotating conical grinding roller 307 cooperates with the fixed grinding table 303 to realize the resin grinding operation.

[0046] The drying assembly 2 also includes a tail cover 208, an exhaust fan 209, and a discharge hopper 210;

[0047] The tail cover 208 is sleeved on the outside of one end of the opening of the drying drum 201, and the tail cover 208 is fixedly connected to the base 101 through the bracket.

[0048] The exhaust fan 209 is installed at the middle of one end of the tail cover 208 to exhaust the moisture inside the drying drum 201.

[0049] The unloading hopper 210 is fixed to the bottom of the tail cover 208 and communicates with the inner cavity of the tail cover 208. The bottom end of the unloading hopper 210 extends to the top of the top plate 304 and is fixedly connected to the top plate 304.

[0050] The top plate 304 has a feed inlet that communicates with the unloading hopper 210.

[0051] In this embodiment: During the resin drying process, the exhaust fan 209 is started simultaneously. The exhaust fan 209 operates to draw air from the inside of the drying drum 201, so that the hot and humid air inside the drying drum 201 can be discharged efficiently.

[0052] Meanwhile, the resin dried by the drying assembly 2 falls into the tail cover 208 through the open end of the drying drum 201, and slides down into the fixed grinding table 303 through the unloading hopper 210. At this time, the second drive motor 306 is started, and the second drive motor 306 drives the conical grinding roller 307 to rotate. The rotating conical grinding roller 307 grinds the resin distributed in the gap between the conical grinding roller 307 and the fixed grinding table 303. The ground resin falls into the collection ring seat 302 and is finally discharged through the discharge plate 305, thus completing the resin grinding operation.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
