Description

Technical Field

[0001] The utility model relates to the field of cooling high-temperature powder materials in polymerization reactions during the production of sodium tripolyphosphate, in particular to an external spraying rotary cooler for sodium tripolyphosphate. Background Art

[0002] Currently, sodium tripolyphosphate is produced through a high-temperature polymerization process. The powder materials produced generally have the characteristics of high temperature. The high-temperature powder materials cause great damage to the equipment during post-processing and transportation. Due to the high temperature of the material, there is a great risk of scalding the bags during the packaging process. In actual production, the initial high-temperature powder materials of sodium tripolyphosphate need to be cooled and pre-treated.

[0003] At present, high-temperature powder materials of sodium tripolyphosphate are mainly cooled by built-in shell-and-tube rotary coolers. First, the device has high requirements on the quality of cooling water. During actual operation, the quality of cooling water will gradually deteriorate and become polluted, leading to scaling inside the tubes, reduced cooling water flow, and poor cooling effect. Second, the built-in tubes of the device are prone to perforation, desoldering and leakage, which cause a series of quality risks such as moisture absorption, caking, hydrolysis and deterioration, and pollution of sodium tripolyphosphate materials. Third, the maintenance of the device is difficult, time-consuming, and frequent, which reduces the start-up rate of the production line. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a sodium tripolyphosphate external spray type rotary cooler structure, which has a simple structure, convenient inspection and maintenance, low failure rate, low requirements for cooling water quality, good material cooling zone effect, avoids direct contact between cooling water and material, and effectively avoids a series of quality risks such as material and water agglomeration, hydrolysis and deterioration, and pollution.

[0005] A novel sodium tripolyphosphate rotary cooler comprises a rotary cooler body, a spray jacket is arranged on the periphery of the rotary cooler body, the upper part of the spray jacket is connected to a cooling water inlet, and the lower part is connected to a cooling water outlet; a spray pipe is arranged inside the spray jacket, and the spray pipe is connected to the lower end of the cooling water inlet.

[0006] The left and right sides of the spray jacket are both provided with an inner water retaining ring and an outer water retaining ring; the inner water retaining ring and the outer water retaining ring are both arranged outside the rotary cooler body and connected to the rotary cooler body; the inner water retaining ring is located between the two outer water retaining rings.

[0007] The rotary cooler body is installed on the front rotary tug and the rear rotary tug via the first and second roller rings.

[0008] A rotating gear is installed at the middle position outside the main body of the rotary cooler. The rotating gear is connected to the reducer, and the reducer is connected to the motor. The rotating gear is located between the front rotating tug and the rear rotating tug.

[0009] The inner wall of the rotary cooler body is equipped with a copy plate.

[0010] The spray system consisting of the spray jacket, cooling water inlet, cooling water outlet, spray pipe, inner water retaining ring and outer water retaining ring is placed statically and does not rotate with the rotating cooler body.

[0011] The spray system is provided with multiple groups.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Cooling water is evenly distributed on the outer wall of the rotary cooler through the spray pipe, indirectly cooling the material. The internal cooling medium of the external spray rotary cooler does not directly contact the high-temperature material. Indirect heat exchange is achieved through the stainless steel outer wall of the rotary cooler, which can effectively avoid a series of quality risks such as moisture absorption, caking, hydrolysis, deterioration, and contamination caused by contact between the material and the cooling water.

[0014] 2. The rotary cooler rotates through the motor, reducer, rotary gear, front and rear tugs. The inner wall of the rotary cooler is equipped with a lifting plate to make the material roll inside the rotary cooler, which is convenient for the material to fully exchange heat and cool.

[0015] 3. The cooling water is collected through the inner water retaining ring, outer water retaining ring, spray jacket and water outlet and then returned to the cooling water circulation pool for recycling, with a return rate of 100%.

[0016] 4. The spray system is fixed on the periphery of the rotary cooler body to form an independent unit. It does not rotate with the rotary cooler body and is in a static spraying state. It has a simple structure, low failure rate and low quality risk. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The embodiments of the present invention will be described in detail below with reference to the examples. The following examples are only used to illustrate the present invention and should not be considered as limiting the scope of the present invention.

[0021] Example 1

[0022] A novel sodium tripolyphosphate rotary cooler includes a rotary cooler body 1. A spray jacket 2 is provided on the periphery of the rotary cooler body 1. The upper part of the spray jacket 2 is connected to a cooling water inlet 3 and the lower part is connected to a cooling water outlet 4. A spray pipe 5 is provided inside the spray jacket 2 and is connected to the lower end of the cooling water inlet 3.

[0023] The left and right sides of the spray jacket 2 are provided with an inner water retaining ring 7 and an outer water retaining ring 6; the inner water retaining ring 7 and the outer water retaining ring 6 are both arranged outside the rotary cooler body 1 and connected to the rotary cooler body 1; Figure 2 As shown, the inner water retaining ring 7 is located between the two outer water retaining rings 6 and on the left and right sides of the spray pipe 5 in the vertical direction.

[0024] The rotary cooler body 1 is installed on the front rotary tug 8 and the rear rotary tug 9 through the roller ring 13 and the roller ring 2 14 .

[0025] A rotating gear 10 is installed in the middle position outside the rotating cooler body 1. The rotating gear 10 is connected to a reducer 11, and the reducer 11 is connected to a motor 12. The rotating gear 10 is located between the front rotating tug 8 and the rear rotating tug 9.

[0026] The inner wall of the rotary cooler body 1 is provided with a lifting plate.

[0027] The spray system consisting of the spray jacket 2 , the cooling water inlet 3 , the cooling water outlet 4 , the spray pipe 5 , the inner water retaining ring 7 and the outer water retaining ring 6 is placed statically and does not rotate with the rotating cooler body 1 .

[0028] The spray system is provided with multiple groups.

[0029] Example 2

[0030] The working principle of this device is as follows:

[0031] The material enters the rotary cooler body 1 through the material inlet, is cooled by the spray system outside the rotary cooler body 1, and is discharged through the material outlet. The inner wall of the rotary cooler body 1 is equipped with a lifting plate, which causes the material to tumble inside the rotary cooler body 1, facilitating sufficient heat exchange and cooling of the material.

[0032] The rotary cooler body 1 is driven by the motor 12, the reducer 11 and the rotary gear 10 to rotate, and the spraying system is in a stationary state and does not rotate with the rotary cooler body, and performs static spraying.

[0033] The cooling principle of the spray system: Cooling water enters the spray pipe 5 inside the spray jacket 2 through the cooling water inlet 3, and is sprayed onto the outer wall of the rotary cooler body 1 through the spray pipe 5, thereby cooling the material inside the rotary cooler body 1. The outer water retaining ring 6 and the inner water retaining ring 7 block and intercept the spray water to improve cooling efficiency; the cooling water then flows out through the cooling water outlet 4 at the bottom of the spray jacket 2 and is collected for reuse. Among them, the outer water retaining ring 6 can effectively prevent the spray water from splashing during the spraying process, and the inner water retaining ring 7 can effectively prevent the cooling water from flowing out along the outer wall of the rotary cooler body 1.

[0034] like Figure 1 As shown, the size and number of the spray systems can be adjusted according to the outer dimensions of the rotary cooler body 1 .
