Technical Field

[0001] The present invention relates to the field of conveyors, and particularly to a molecular sieve raw material conveyor. Background Art

[0002] The flower arranging mud made of phenolic plastic foam as a molecular sieve raw material needs to be crushed and dried. Since the crusher has the problem of incomplete crushing and there is waste heat resource in the drying process, the conveyor used between the current crushing and drying processes has sufficient contact time with the crushed material during the transfer of the crushed material. Therefore, it is necessary to develop a conveying device with both waste heat utilization and crushed material screening functions to optimize the production process. Summary of the Invention

[0003] The purpose of the present invention is to provide a molecular sieve raw material conveyor to solve the above technical problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions to achieve:

[0005] A molecular sieve raw material conveyor includes a screw conveyor mechanism. There is a feed cylinder in the feeding area of the screw conveyor mechanism. Inside the feed cylinder is a drum, and the drum is a hollow structure;

[0006] There are also several equally spaced annular grooves on the surface of the drum;

[0007] On both sides of the drum are side plates. The side plates are the rotating support parts of the drum. The side plates also have extension parts, and the extension parts are connected to the barrel wall of the feed cylinder. On the other two sides of the drum are baffles connected to the two side plates;

[0008] The combination of the baffle and the side plate divides the feed cylinder into two parts. One part serves as the storage space of the feed cylinder, and the other part is connected to the screw conveyor mechanism;

[0009] The baffle is equipped with a baffle extension part that enters the annular groove. The baffle extension part forms a sieve hole in the annular groove, and the sieve hole is the channel for the above two parts;

[0010] The internal space of the drum is exposed outward from the extension part at the side plate. One of the exposed parts inserts a waste heat pipe, and the waste heat pipe introduces hot air into the drum. The source of the hot air is the waste heat during the operation of the dryer;

[0011] Another exposed part inserts a second shaft. The second shaft enters the drum. It also includes a plurality of perforated partitions fixedly connected to the second shaft in the drum. The perforated partitions are first connected to the inner wall of the drum in the drum, and secondly, can contact the hot air, so that the surface of the drum has a certain amount of heat to heat the crushed material in contact with the drum;

[0012] The second shaft also has a driving part, which drives the second shaft to rotate axially. When the drum rotates relative to the combination of the baffle and the side plate, the crushed material poured into the feeding cylinder is fully contacted with the drum and then discharged through the sieve holes.

[0013] Preferably, the combination of the baffle and the side plate can rotate in the feeding cylinder and can be fixed in the feeding cylinder after rotation.

[0014] Preferably, the extension part at the side plate is rotationally matched with the feeding cylinder. The extension part of one side plate penetrates through the feeding cylinder and extends outwards. The outward extension part has threads, and a screw sleeve is also included. The screw sleeve is sleeved on the threads and closely adheres to the feeding cylinder, so that the combination is fixed in the feeding cylinder.

[0015] Preferably, the side plate extension parts all have channels. The channel of one extension part is communicated with the waste heat pipe, and the second shaft is inserted into another extension part to form an annular cavity, and the annular cavity is used to discharge the hot air in the drum.

[0016] Preferably, the feeding cylinder has a notch, and a flap is hinged at the notch. The flap has a bend. When the flap covers the notch, one of the baffles is stuck at the bend of the flap.

[0017] Preferably, the sieve hole size is adjustable.

[0018] Preferably, an elastic plate is above the baffle. The elastic plate extends into the annular groove. The elastic plate can move relative to the baffle, and the sieve hole size can be adjusted during the movement.

[0019] Preferably, the baffle has a strip-shaped groove, and the elastic plate is also provided with bolts that extend into the strip-shaped groove and extend outwards. The part of the bolt extending outwards relative to the strip-shaped groove is provided with nuts, and the nuts cooperate with the bolts to fix the elastic plate at the baffle.

[0020] Preferably, a stop block is arranged in the annular groove. The stop block contacts the extension part of the elastic plate extending into the annular groove when the drum rotates clockwise and counterclockwise alternately, and ejects the broken material stuck in the sieve holes.

[0021] Preferably, the stop block is below the drum, and after the stop block contacts the extension part of the elastic plate, the drum will rotate in the reverse direction.

[0022] The beneficial effects of the present invention are as follows:

[0023] By introducing the residual heat of the drying process into the conveyor in the form of air flow, the present invention realizes the preheating treatment of the crushed material to improve the thermal energy utilization efficiency. At the same time, a screening system is integrated in the conveyor to perform secondary screening on the crushed material during the conveying process, intercept the raw material particles that are not fully broken, and avoid them entering the drying process and affecting the product quality.

[0050] Consistent with Embodiment 1, the screening and waste heat recycling system is mainly arranged in the area where the feed cylinder 4 is located. The feed cylinder 4 is a cylinder with a corner, and its internal space can be divided into an upper cavity and a lower cavity based on the above-mentioned corner. In addition, the feed cylinder 4 has a notch, and a flap 9 is connected to the notch by a hinge. The flap 9 can cover the notch, and a bolt 10 can also be used to fix the flap 9 at the notch. There is a drum 15 inside the feed cylinder 4. The drum 15 is a hollow structure, and there are several equidistant annular grooves on the surface of the drum 15. Both sides of the drum 15 are open barrel openings, and of course the barrel openings need to be closed. The structure used for closing is the side plate 14. The side plate 14 coincides with the axis of the drum 15, and the side plate 14 is also the rotation support part of the drum 15.

[0051] Consistent with Embodiment 1, both side plates 14 have extension parts. The extension parts of the two side plates 14 are the first side plate extension part 16 and the second side plate extension part 19 respectively. There are channels at the axes of the first side plate extension part 16 and the second side plate extension part 19. In addition, the surface of the second side plate extension part 19 also has threads. Further, the first side plate extension part 16 is inserted into the bearing provided at the side wall of the feeding cylinder 4, and the second side plate extension part 19 is inserted into the bearing provided at the other side wall of the feeding cylinder 4, and the threaded part also extends outwards relative to the bearing, and a screw sleeve is provided at the extended part.

[0052] Consistent with Embodiment 1, the other two sides of the roller 15 are baffles 13. The baffles 13 are connected to the above-mentioned side plates 14. After connection, the combination of the baffles 13 and the side plates 14 divides the feeding cylinder 4 into two parts, and the two parts respectively correspond to the above-mentioned upper cavity and lower cavity. Further, the above combination can rotate in the feeding cylinder 4. Of course, it can also be fixed after rotation, and the fixing method is based on the screw sleeve being sleeved on the threaded part and being in close contact with the barrel wall of the feeding cylinder 4. It should be noted that the flap 9 also has a bend angle. When the flap 9 covers the notch, the bend angle will be stuck at the baffle 13, thereby further fixing the combination.

[0053] Consistent with Embodiment 1, the baffle 13 has a baffle extension part 18 that enters the annular groove. The baffle extension part 18 forms a sieve hole in the annular groove, and the sieve hole can communicate the above-mentioned upper cavity and lower cavity. The internal space of the roller 15 can be exposed outward based on the first side plate extension part 16 and the second side plate extension part 19. Among them, the second shaft 11 is sleeved in the first side plate extension part 16, and the second shaft 11 extends into the roller 15, and the extended part is connected to a plurality of perforated partitions 17 connected to the inner wall of the roller 15. The second side plate extension part 19 is connected to the waste heat pipe. After connection, the waste heat in the drying unit can be introduced into the roller 15 by means of air flow. A gear 12 is installed on the part of the second shaft 11 outside the feeding cylinder 4. In addition, a second driving part 7 engaged with the gear 12 is also installed on the outer wall of the feeding cylinder 4. The second driving part 7 can transmit power to the roller 15, so that the roller 15 can rotate relative to the combination of the above-mentioned baffle 13 and side plate 14. During rotation, the crushed material is poured into the upper cavity, so as to uniformly heat the crushed material by means of the heat on the surface of the roller 15, and screen the crushed material based on the sieve hole during the heating process, and intercept the unqualified crushed material in the upper cavity.

[0054] Different from Embodiment 1, in this embodiment, the size of the sieve hole can be adjusted. Please refer to Figures 12 - 14 , an elastic plate 20 is provided above the baffle 13. The elastic plate 20 extends into the annular tooth groove. Among them, the maximum extension amount of the elastic plate 20 is to contact the bottom of the annular groove. In addition, the elastic plate 20 can also move relative to the baffle 13. During the movement, the size of the sieve hole changes. Thus, the size of the sieve hole can be adaptively adjusted according to the requirements of the customer for the crushed material. Please refer toFigure 13 and Figure 14 , the baffle 13 has a strip groove (not shown in the figure). The elastic plate 20 is provided with a bolt 21 extending into the strip groove and protruding outwards from the other side of the strip groove. The part of the bolt 21 protruding outwards relative to the strip groove is provided with a nut 23. The nut 23 cooperates with the bolt 21 to fix the elastic plate 20 at the baffle 13 after the sieve hole size is determined. In this embodiment, in order to clean the crushed material stuck in the sieve hole, a stop block 22 is further provided. The stop block 22 is in the annular groove and in the area where the lower cavity is located. The function of the stop block 22 is to eject the broken material stuck in the sieve hole by contacting the extension part of the elastic plate 20 in the annular groove when the roller 15 rotates clockwise and counterclockwise alternately. It should be noted that after adding the structure of the stop block 22, the rotation action of the roller 15 is limited to rotating clockwise and counterclockwise alternately, and the stop block 22 should also be prevented from crossing the elastic plate 20.

[0055] The molecular sieve raw material conveyor proposed in Embodiment 1 and Embodiment 2 has another function. As introduced in each embodiment, the combination of the baffle 13 and the side plate 14 can rotate relative to the feed cylinder 4. This setting can, after a certain amount of unqualified crushed material accumulates in the upper cavity, by screwing out the flap 9 from the notch, after the rotation function of the combination is unlocked, quickly rotate the combination to throw out the unqualified crushed material in the upper cavity.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
