Description

Technical Field

[0001] The utility model relates to the field of drum drying equipment, in particular to a spray-type chemical drum drying equipment. Background Art

[0002] During the chemical production process, the drum is usually set in the product drying link of the process link, and the purpose of drying the product is mainly achieved by heating the oil on its surface through steam or heat conduction.

[0003] During the production process, the drying drum equipment operates in a semi-immersed tank. The liquid is affected by the friction of the drum surface and spreads on the drum surface as the drum rotates. It absorbs the heat of the drum and evaporates and crystallizes. This drying process technology has defects. The liquid at the end of the chemical production process is highly concentrated, chemically active, and highly corrosive. In addition, the drum body material must be made of carbon steel due to surface friction. The drum wear rate is extremely high under this working condition for a long time, and even a set of drums needs to be replaced every six months for production. At the same time, half of the drum is immersed in the liquid, and nearly half of the drying area is not utilized, wasting heat exchange efficiency. On the other hand, the liquid is only slightly lifted by the friction of the drum surface, and only a thin layer of product can be formed after the drum is heated and dried, reducing the production capacity of the drum-dried finished products.

[0004] In addition, the semi-submerged drum is also heating the slurry. The high-concentration slurry is chemically active and easily reacts when heated to produce viscous precipitation. Manpower is required to regularly remove the sediment at the bottom of the slurry pool, which seriously reduces the drying capacity. Utility Model Content

The spray-type chemical drum drying equipment sprays liquid through the spray pipe. The liquid is subjected to the friction of the surface of the heating drum and is uniformly distributed through the mesh cloth along with the rotation of the heating drum for the first time. Then, it is evenly distributed through the brush and the liquid is evenly distributed for the second time. As the heating drum rotates, the material is evenly coated on the surface of the heating drum. The heating drum is then heated and evaporated for drying.

[0007] As a preferred technical means: the upper end of the main support is provided with a brush reciprocating mechanism, and the brush is connected to the reciprocating mechanism. This allows the brush to reciprocate along the surface of the heating drum during operation, thereby enhancing the uniformity of the liquid distribution and improving the drying efficiency.

[0008] As a preferred technical approach, an auxiliary fixing plate is connected to the top left side of the main support, to which the front and rear ends of the spray pipe are connected.

The scraper is located on the right side of the spring bracket, elastically contacting the left side of the heating drum. The spring bracket is connected to the left end of the horizontal support rod. The scraper elastically contacts the heating drum surface through the spring bracket. This structure can adapt to slight deformations and unevenness of the heating drum, maintaining close contact between the scraper and the drum surface, effectively removing residual material from the drum surface and preventing material accumulation that affects the drying effect.

[0011] As a preferred technical approach, the spring support comprises a left support rod, a spring support rod, and a spring. The spring is sleeved onto the right side of the spring support rod, the left end of the spring support rod being fixedly connected to the left support rod, the right end of the spring support rod being slidably connected to the scraper, and the spring elastically engages the scraper at the right end. The spring and spring support rod form an elastic assembly, multiple of which are arranged in a front-to-back array.

Gear train transmission structures are relatively easy to maintain, allowing for easy replacement or repair of worn gears. Gear train transmission systems are typically compact, effectively utilizing limited space. An interference fit or keyed connection between the shaft and the mounting plate ensures more secure shaft fixation, preventing loosening or slipping during operation and ensuring long-term stable operation of the transmission system.

[0025] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figure 1 、 2As shown, a spray-type chemical drum drying equipment includes a machine base 1, a main bracket 2, a heating drum 3, a mesh 4, a spray pipe 5, a row brush 6 and a scraper 10. The heating drum 3 is rotatably connected to the machine base 1. The axial direction of the heating drum 3 is front-to-back. The main bracket 2 is arranged in the left area above the machine base 1. The main bracket 2 includes a front bracket and a rear bracket. The front bracket and the rear bracket both include a vertical bracket rod 202 and a horizontal bracket rod 201. The horizontal bracket rod 201 is connected and fixed to the left side of the lower middle part of the vertical bracket rod 202. The row brush 6 is arranged at the upper end of the main bracket 2. The bristles of the row brush 6 are in contact with the upper left cylinder surface of the heating drum 3, and the bristles are facing to the right. The upper end of the main bracket 2 is provided with a row brush reciprocating movement mechanism 11. The row brush reciprocating movement mechanism 11 is connected to the two front and rear vertical bracket rods 202, and the row brush 6 is connected to the reciprocating movement device. One end of the mesh 4 is connected to the left end of the brush handle of the row brush 6 through the first mesh roller 7. The other end of the mesh 4 passes through the sponge roller 8 and is then rolled upward on the second mesh roller 9. A roller seat plate 13 is provided on each of the front and rear horizontal support rods 201. The front and rear ends of the sponge roller 8 are rotatably connected to the roller seat plate 13. The mesh 4 is in contact with the surface of the heating drum 3. An auxiliary fixing plate 12 is connected to the top left side of the main support 2. There are two auxiliary fixing plates 12, which are respectively connected and fixed to the front and rear vertical support rods 202. The axial direction of the spray pipe 5 is forward and backward. The front and rear ends of the spray pipe 5 are connected to the auxiliary fixing plate 12. The bottom of the spray pipe 5 has downward-facing nozzles arranged in a forward and backward array. The spray pipe 5 is connected to the feeding device. The left ends of the front and rear horizontal support rods 201 are connected to the front and rear spring supports 14, and the scraper 10 is connected to the right side of the spring support 14. The blade head of the scraper 10 faces downward and elastically presses against the left side surface of the heating roller 3. The scraper 10 is located below the sponge roller shaft 8, and the heating roller 3 is connected to the drive device.

[0028] To achieve elastic support for the scraper 10 by the spring support 14, the spring support 14 includes a left support rod 1401, a spring support rod 1402, and a spring 1403. The spring 1403 is sleeved on the right side of the spring support rod 1402. The left end of the spring support rod 1402 is connected and fixed to the left support rod 1401. The right end of the spring support rod 1402 is slidably connected to the scraper 10. The spring 1403 elastically connects to the scraper 10 at the right end. The spring 1403 and the spring support rod 1402 form an elastic assembly. Six elastic assemblies are arranged in a front-to-back array. The front and rear ends of the left support rod 1401 are respectively connected to the left ends of the two front and rear horizontal support rods 201. This structure effectively achieves elastic support for the scraper 10 by the spring support 14. By arranging six elastic assemblies, the stability of the structure is effectively improved.

[0029] To achieve both rotation and internal heating, the heating drum 3 is a hollow cylinder. One end of the drum's front-to-back direction is a drive shaft connected to the drive unit, while the other end is a hollow shaft connected to the interior of the drum and connected to the steam heating unit. This ensures both rotation and internal heating, ensuring the proper operation and efficient performance of the drying equipment.

[0030] After the equipment is installed, wind the second mesh roller 9 to tighten the mesh 4 and bring it into contact with the surface of the heating drum 3. The spray pipe 5 and auxiliary fixing plate 12 are removable for easy cleaning and maintenance. A storage hopper is located below the heating drum 3. The left side of the storage hopper is located to the left of the scraper 10, providing a temporary storage area for the dried material scraped by the scraper 10. The storage hopper is equipped with a discharge mechanism to facilitate uninterrupted discharge. A frequency converter cabinet is installed to enable the pump to operate at a specific frequency.

[0031] After the equipment is started, the spray pipe 5 sprays the material liquid downward from each nozzle, and the heating drum 3 rotates. The material liquid is subjected to the friction force on the surface of the heating drum 3 and is uniformly distributed for the first time along with the rotation of the heating drum 3 through the grid-shaped uniformly distributed mesh cloth 4, and then passes through the reciprocating brush 6 to distribute the material evenly, so that the material is evenly coated on the surface of the heating drum 3, and then the heating drum 3 is heated and evaporated for drying. On the other hand, the excess material liquid on the upper side of the heating drum 3 will be collected and evenly distributed by the sponge roller 8, and then heated and dried as the heating drum 3 rotates clockwise, and finally the scraper 10 is used to clean the material on the drum surface, thereby achieving uniform drying and efficient cleaning of the material. Compared with traditional drying equipment, since the material pool is eliminated, the drying working area of ​​the heating drum 3 is increased, which can effectively increase the production capacity by more than 3 times, reduce the use of a large amount of steam, extend the working life of the equipment, and no longer need to manually clean the material pool sedimentation work, reducing labor costs.

[0032] In this example, the base 1 and main support 2 are made of angle steel or other shaped steel materials. The left support rod 1401 is made of round steel pipe, square steel pipe, angle steel or other shaped steel materials, and can be connected by welding or fasteners. The spring support rod 1402 is made of threaded round steel, and a nut 1404 is screwed into the middle portion to adjust the pre-tightening of the spring 1403.

[0033] Example 2:

[0034] The same points as in Example 1 are not described in detail here, except that:

[0035] like Figure 3As shown, the reciprocating movement device of the brush row 6 includes a fixed plate 1104, a guide rail 1102 provided on the fixed plate 1104, an output rod 1101 slidingly connected to the guide rail 1102, a connecting rod 1103 hinged at one end to the output rod 1101, an input rod 1105 connected to the other end of the connecting rod 1103, and a motor driving the input rod 1105 to rotate, the input rod 1105 has a guide groove, the other end of the connecting rod 1103 is slidingly connected to the guide groove, the brush row 6 is connected to the output rod 1101; the fixed plate 1104 is fixedly connected to the main bracket 2.

[0036] Through the mutual cooperation of the fixing plate 1104, the guide rail 1102, the connecting rod 1103 and other components, the brush 6 can be moved back and forth smoothly, effectively improving the structural stability of the equipment and reducing the failure rate during operation.

[0037] The motor drives the input rod 1105 to rotate, and the connecting rod 1103 system drives the output rod 1101 and the row brush 6 to move, so that the row brush 6 can make precise reciprocating motion on the guide rail 1102, and the operation is more reliable.

[0038] To simplify the structure, the input rod 1105 is rotatably connected to the fixed plate 1104 via a rotating shaft 1106. The motor drives the rotating shaft 1106 to rotate via a connecting member, thereby rotating the input rod 1105. The connecting member can be a coupling, gear, belt, chain, etc.

[0039] In this embodiment, the connecting member is a gear set, and the motor drives the rotating shaft 1106 to rotate through the gear set; the rotating shaft 1106 and the fixed plate 1104 are connected by a key; a bearing is provided between the rotating shaft 1106 and the fixed plate 1104.

[0040] Through the transmission of the gear set, the motor can efficiently transmit power to the rotating shaft 1106. The gear set has high transmission efficiency and reliability. The gear transmission can accurately control the rotation angle and speed of the rotating shaft 1106, ensuring the precise movement of the input rod 1105; the gear set transmission structure is relatively easy to maintain, and the gears can be replaced or repaired more conveniently after wear; the gear set transmission system is usually compact in design, which can effectively utilize limited space. The interference fit or key connection between the rotating shaft 1106 and the fixed plate 1104 makes the fixation of the rotating shaft 1106 more reliable, prevents loosening or slipping during operation, and ensures long-term stable operation of the transmission system. The key and the rotating shaft 1106 can be integrated or split. For example, the rotating shaft 1106 can be a spline shaft, and the rotating shaft 1106 hole of the fixed plate 1104 matches the spline shaft.

[0041] To improve the compactness of the structure, the motor and gear set are located on the back of the fixed plate 1104. The driven gear can be directly fixed on the extended rotating shaft 1106.

[0042] During operation, the motor rotates, driving the driving gear in the gear set to rotate, and the driven gear meshing with it rotates, and drives the rotating shaft 1106 to rotate. The rotating shaft 1106 drives the input rod 1105 to rotate, causing the connecting rod 1103 with one end located in the guide groove to swing, and the connecting rod 1103 pulls the output rod 1101 to move back and forth.

[0043] The spray-type chemical drum drying equipment shown above is a specific embodiment of the present invention, which has embodied the outstanding substantial features and significant progress of the present invention. According to actual use needs, under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the scope of protection of this scheme.
