Abstract
Description
Technical Field
[0001] The present invention relates to the field of dryers, and in particular to a multi-stage dryer and a method for producing chlorinated paraffin. Background Art
[0002] In the existing process of drying chlorinated paraffin powder, when it is dried by a traditional disc dryer, the disc dryer is composed of multiple staggered drying discs from top to bottom, and the staggered drying discs are divided into large and small discs, that is, a large disc and a small disc are staggered and arranged up and down, and a through hole is opened in the middle of the large disc. Then, a continuously rotating push plate is used to push the chlorinated paraffin powder through the through hole in the middle of the small disc, causing it to fall onto the small disc. Then, the continuously rotating push plate pushes the chlorinated paraffin powder toward the side of the small disc away from the center of the circle, pushing the transmission wheel, causing it to fall onto the large disc. This reciprocating process is repeated in multiple layers, thereby gradually drying the chlorinated paraffin powder. However, in the process of pushing the chlorinated paraffin powder, since the push plate gradually pushes the chlorinated paraffin powder to accumulate, there is an obvious accumulation problem of the chlorinated paraffin powder during the pushing process, which leads to incomplete drying and agglomeration.
[0003] Therefore, in order to solve the above problems, the present application designs a multi-stage drying machine for the production of chlorinated paraffin. Summary of the Invention

[0006] As a further preferred solution, the transmission assembly includes a drive motor, a transmission column, a first fixed rod and a second fixed rod; the drive motor is installed on the mounting base; the transmission column is fixedly connected to the output end of the drive motor; multiple layers of first fixed rods are installed on the cylinder from top to bottom, and each layer is provided with four first fixed rods; multiple layers of second fixed rods are installed on the cylinder from top to bottom, and each layer is provided with four second fixed rods; the four first fixed rods on each layer are commonly fixed to the corresponding small drying plate; the four second fixed rods on each layer are commonly fixed to the corresponding large drying plate.
[0007] As a further preferred solution, each small drying plate and large drying plate is provided with a plurality of oblique material dropout chutes arranged in a circular array, and the oblique material dropout chutes on the upper and lower adjacent small drying plates and large drying plates are staggered.
[0008] As a further preferred solution, the oblique-mouthed blanking chutes on the same small drying plate and large drying plate are staggered.
[0009] As a further preferred solution, the scrapers and the oblique-mouth troughs are arranged in multiple groups in a circular array from the inside to the outside, and each scraper corresponds to the position of the corresponding oblique-mouth trough.
[0010] As a further preferred solution, the side of the scraper is arranged as a slope, and the slope of the scraper on the small drying plate is arranged so that the height of the side close to the oblique material trough is lower than the height of the side away from the oblique material trough, while the slope of the scraper on the large drying plate is arranged in the opposite manner.
[0011] As a further preferred solution, a dredging assembly is also included. Several dredging assemblies are installed on each small drying plate and the large drying plate. The following description takes one dredging assembly as an example. The dredging assembly includes a linkage block, a separator, a crank connecting bar and a fixed shaft; two fixed shafts are provided on both sides of the oblique material chute of the small drying plate; two separators for dredging the oblique material chute are fixedly connected between the four fixed shafts; the two fixed shafts located above are each equipped with a crank connecting bar through a torsion spring; and a linkage block is fixedly connected to each of the two crank connecting bars.
[0012] As a further preferred solution, the separator is configured to be corrugated.
[0013] As a further preferred solution, two adjacent linkage blocks are respectively located on both sides of the oblique blanking trough, and the upper surfaces are arc-shaped surfaces.
[0014] A method for operating a multi-stage dryer for producing chlorinated paraffin includes the following working processes:

At the same time, the feeding of the chlorinated paraffin powder is dispersed in sections, effectively accelerating its drying rate.
[0019] The side of the scraper is set as an inclined surface, and the chlorinated paraffin powder flows from the position of the scraper close to the drying cylinder to the position away from the drying cylinder, so that the material continuously moves toward the inclined feeding chute, thereby preventing the chlorinated paraffin powder from accumulating on the inclined feeding chute, resulting in the chlorinated paraffin powder not being able to be transported downward in time and being over-dried;
[0020] The scraper squeezes the linkage block, causing the two separators located in the oblique-mouth chute to rotate, and the two separators rotate in a staggered manner close to each other, thereby clearing the oblique-mouth chute and squeezing and crushing the chlorinated paraffin powder that may have lumps and blocked the oblique-mouth chute, thereby preventing it from agglomerating and being unable to dry, and affecting its normal feeding.

[0032] The drying machine further comprises a transmission assembly, a small drying plate 104, a large drying plate 105, a connecting rod 106 and a scraper 107; the transmission assembly is mounted on the cylinder 2; a plurality of small drying plates 104 and large drying plates 105 are staggeredly mounted on the transmission assembly from top to bottom, and the plurality of small drying plates 104 and large drying plates 105 are all located inside the cylinder 2; a plurality of connecting rods 106 are fixedly connected to the transmission assembly from top to bottom by springs; a plurality of scrapers 107 are mounted on each connecting rod 106.
[0033] The transmission assembly includes a drive motor 101, a transmission column 102, a first fixed rod 103 and a second fixed rod 108; the drive motor 101 is installed on the mounting base 1; the transmission column 102 is fixedly connected to the output end of the drive motor 101; multiple layers of first fixed rods 103 are installed on the cylinder 2 from top to bottom, and each layer is provided with four first fixed rods 103; multiple layers of second fixed rods 108 are installed on the cylinder 2 from top to bottom, and each layer is provided with four second fixed rods 108; the four first fixed rods 103 on each layer are fixedly connected to the corresponding small drying plate 104; and the four second fixed rods 108 on each layer are fixedly connected to the corresponding large drying plate 105.
[0034] Each small drying plate 104 and large drying plate 105 is provided with a plurality of oblique material dropping grooves 1041 arranged in a circular array, and the oblique material dropping grooves 1041 on the upper and lower adjacent small drying plates 104 and large drying plates 105 are staggered.
[0035] The oblique-mouthed blanking chutes 1041 located on the same small drying plate 104 and large drying plate 105 are all staggered.
[0036] The scrapers 107 and the oblique-mouthed material troughs 1041 are arranged in a plurality of groups in a circular array from the inside to the outside, and each scraper 107 corresponds to the position of the corresponding oblique-mouthed material trough 1041 .
[0037] The side of the scraper 107 is set to be an inclined surface, and the inclined surface of the scraper 107 on the small drying plate 104 is set to be lower than the side away from the inclined material trough 1041, while the inclined surface of the scraper 107 on the large drying plate 105 is set in the opposite way.
[0038] The cover body 3 is provided with a feed port for adding materials.
[0039] Specific working process: Before starting the drying work, manually add chlorinated paraffin powder to the small drying plate 104 on the top layer through the feed port, start the external heater, and then start the drive motor 101. The drive motor 101 drives the transmission column 102 to rotate. As viewed from top to bottom, the transmission column 102 rotates clockwise, and then drives all the connecting rods 106 to start rotating through the transmission column 102, that is, all the scrapers 107 start rotating. When the scrapers 107 rotate, the scrapers 107 on the small drying plate 104 gradually push the accumulated chlorinated paraffin powder to the side of the small drying plate 104 away from the center of the circle, so that The chlorinated paraffin powder gradually falls from the small drying plate 104 on the top layer to the large drying plate 105 on the adjacent lower layer, and then the corresponding scraper 107 pushes the chlorinated paraffin powder on the large drying plate 105 toward the center of the circle of the large drying plate 105, and then makes it fall from the through hole at the center of the circle to the small drying plate 104 on the next layer. This cycle is repeated many times until the chlorinated paraffin powder is dried and discharged. In the above working process, since the chlorinated paraffin powder can only be discharged through the outer edge of the small drying plate 104 and the central through hole of the large drying plate 105, it needs to be pushed many times to achieve discharge during the discharge process. There is a process in which the material gradually accumulates, resulting in a high height of the material accumulation, which makes it difficult to dry quickly. Therefore, in order to solve this drawback, an oblique material drop trough 1041 is provided on the small drying plate 104 and the large drying plate 105, so that when the material does not need to be pushed to the edge of the small drying plate 104 and the center of the large drying plate 105, the chlorinated paraffin powder can also be gradually discharged, avoiding a large amount of material accumulation during the pushing process, affecting its drying. At the same time, the staged dispersion of the chlorinated paraffin powder can also effectively speed up its drying rate. At the same time, when the scraper 107 gradually pushes the material to move toward the oblique material drop trough 1041, and through the oblique During the process of dropping from the oblique opening chute 1041, the chlorinated paraffin powder is accumulated, and it may cause the chlorinated paraffin powder to block the oblique opening chute 1041, or the chlorinated paraffin powder may accumulate on both sides of the oblique opening chute 1041. Therefore, the side of the scraper 107 is set to be an inclined surface, and the height of the inclined surface is set to be lower than the height of the side away from the oblique opening chute 1041. The inclined surface of the scraper 107 on the large drying plate 105 is set in the opposite direction. Then, when the material is gradually pushed, the chlorinated paraffin powder automatically moves on the inclined surface of the scraper 107 toward the side close to the corresponding inclined direction, as shown in FIG. Figure 6As shown, the chlorinated paraffin powder flows from the position of the scraper 107 close to the drying cylinder 22 to the position away from the drying cylinder 22, realizing the process of continuous movement of the material toward the oblique feeding chute 1041, thereby avoiding the accumulation of chlorinated paraffin powder on the oblique feeding chute 1041, resulting in the chlorinated paraffin powder being unable to be transmitted downward in time and being over-dried. At the same time, when the chlorinated paraffin powder is pushed toward the oblique feeding chute 1041, the flowable chlorinated paraffin powder is also conducive to its smooth transportation to the next layer, thereby effectively accelerating the drying rate and improving the drying effect.
[0040] Furthermore, each small drying plate 104 and large drying plate 105 is provided with a plurality of oblique material dropping chutes 1041 arranged in a circular array, and the oblique material dropping chutes 1041 on the upper and lower adjacent small drying plates 104 and large drying plates 105 are staggered to prevent the material from directly falling through the interconnected oblique material dropping chutes 1041 directly onto the small drying plates 104 and large drying plates 105 below, resulting in insufficient drying time and affecting normal drying.
[0041] Example 2
[0042] On the basis of Example 1, Figure 5-Figure 7 As shown, a dredging assembly is also included. Several dredging assemblies are installed on each small drying plate 104 and the large drying plate 105. The following description takes one dredging assembly as an example. The dredging assembly includes a linkage block 201, a separator 202, a crank connecting bar 203 and a fixed shaft 204; two fixed shafts 204 are provided on both sides of the oblique blanking chute 1041 of the small drying plate 104; two separators 202 are fixedly connected between the four fixed shafts 204; the two fixed shafts 204 located above are each installed with a crank connecting bar 203 through a torsion spring; a linkage block 201 is fixed to each of the two crank connecting bars 203, and the upper surface of the linkage block 201 is an arc-shaped surface.
[0043] The separator 202 is configured to be corrugated, which is beneficial for secondary crushing of the agglomerated material to avoid agglomeration and affect drying.
[0044] Two adjacent linkage blocks 201 are respectively located on both sides of the oblique blanking trough 1041, and the upper surfaces thereof are arc-shaped surfaces.
[0045] In the process of chlorinated paraffin powder falling from the oblique material chute 1041, in order to prevent it from clogging the oblique material chute 1041 due to problems such as agglomeration, and in order to speed up its discharge rate, when the scraper 107 passes through the oblique material chute 1041, it contacts the corresponding linkage block 201, and then squeezes the linkage block 201 through the scraper 107, so that the two partitions 202 located in the oblique material chute 1041 rotate, and the two partitions 202 rotate in a staggered manner close to each other, thereby clearing the oblique material chute 1041 and squeezing and crushing the chlorinated paraffin powder that may have lumps and clog the oblique material chute 1041, so as to prevent it from agglomerating and being unable to dry, and affecting its normal discharge.
[0046] A method for operating a multi-stage dryer for producing chlorinated paraffin includes the following working processes:
[0047] S1: feeding, manually adding chlorinated paraffin powder to the topmost small drying plate (104) of the cylinder (2);
[0048] S2: feeding and drying, the chlorinated paraffin powder is pushed layer by layer to the oblique feeding chute (1041) by the scraper (107) to avoid accumulation and achieve the effect of accelerating drying;
