The shaft sleeve 3h is fixedly connected with the main shaft 3g, is sealed with the main shaft 3g and floats along with the main shaft 3 g; the bellows 5 can compensate the elongation of the main shaft 3g in the heating and drying process, and the sealing seat 6 is sleeved on the shaft sleeve 3h and can slide left and right to adapt to the expansion amount caused by temperature change; the packing 7 is pressed in the packing box of the seal seat 6 by the seal gland 8, so that the sealing effect between the seal seat 6 and the shaft sleeve 3h can be ensured when the main shaft 3g floats.

The stuffing 7 is provided with a plurality of pairs along the axial direction of the stuffing box, each pair of stuffing comprises an inner ring stuffing 7a and an outer ring stuffing 7b, the inner peripheral wall of each inner ring stuffing 7a is respectively pressed on the outer wall of the shaft sleeve 3h, the outer wall of each outer ring stuffing 7b is respectively pressed on the inner wall of the stuffing box, each inner ring stuffing 7a and each outer ring stuffing 7b are mutually attached through a conical surface, and the included angle between each conical surface and the axial line is 45 degrees. The inner circumference and the outer circumference of the traditional packing are respectively used as sealing surfaces, the packing is flattened by the pressure of a sealing gland 8, and the inner circumference and the outer circumference expand and are simultaneously compressed with the sealing surfaces at two sides; because the elastic deformation capacity of the filler is limited and the extrusion is insufficient, the compression of both sides is difficult to ensure, and the excessive extrusion can cause the filler to lose the elastic deformation capacity and lose effectiveness easily. According to the invention, the inner ring packing 7a and the outer ring packing 7b which are matched with each other in the conical surface are adopted, when the axial extrusion force of the sealing gland 8 is received, the inner ring packing 7a and the outer ring packing 7b respectively slide along the conical surface, the inner wall of the inner ring packing 7a is sealed with the outer wall of the shaft sleeve 3h, and the outer wall of the outer ring packing 7b is sealed with the sealing seat 6, so that reliable sealing can be ensured without excessive extrusion force, the packing is kept in an elastic deformation state, the service life is long, and the reliability is good.

A cylinder base 11 is arranged below the cylinder 1, and the left, middle and right ends of the cylinder base 11 are respectively provided with a base support lug 12 standing upwards; the bottom at barrel both ends is equipped with left branch foot 1d and right branch foot 1e respectively, and the middle section of barrel bottom is equipped with well stabilizer blade 1f, and the lower extreme of left branch foot 1d articulates on the base journal stirrup 12 of left end through barrel free bearing 1g, and well stabilizer blade 1f and right branch foot 1e are connected with downwardly extending's barrel adjusting screw 1h respectively, and the lower extreme of barrel adjusting screw 1h articulates on corresponding base journal stirrup 12 respectively. Through rotating barrel adjusting screw 1h, can make barrel 1 take place the swing around the round pin axle of barrel free bearing 1g to change the slope between barrel axis and the horizontal plane, in order to change ejection of compact speed, ensure that organic impurity can not be the caking in barrel 1, in order to adapt to the stoving sterilization of multiple organic impurity.

The heating jacket 1c covers the periphery of the middle lower part of the cylinder 1, and high-temperature saturated steam is introduced into the heating jacket 1c to heat the organic impurities in the inner cavity of the cylinder and raise the temperature of the organic impurities so as to quickly reach the temperature for sterilizing bacteria.

The top of barrel 1 is connected with fire control steam interface 1j, sight glass 1m and barrel access hole 1k, and fire control steam interface 1j department installs the fire control steam valve that communicates with each other with the steam conduit, and the barrel end plate 2 upper portion of discharge end is equipped with end plate access hole 2c. When a fire occurs in the barrel body 1, the fire-fighting steam valve is opened, a large amount of steam enters the inner cavity of the barrel body 1 from the fire-fighting steam port 1j, oxygen is discharged, open fire can be rapidly extinguished, and the safety production of equipment is guaranteed.

As shown in fig. 7 and 8, the double rotary valve 9 includes an upper housing 9a and a lower housing 9b which are through, an inner cavity of the upper housing 9a is provided with an upper rotary valve 9h, an upper valve rotating shaft 9h1 is provided along an axis of the upper rotary valve 9h, an inner cavity of the lower housing 9b is provided with a lower rotary valve 9p, and a lower valve rotating shaft 9p1 is provided along an axis of the lower rotary valve 9 p; the front end of the upper valve rotating shaft 9h1 is provided with an upper valve chain wheel I9 g, the upper valve chain wheel I9 g is connected with a main chain wheel 9e through a chain I9 f, the main chain wheel 9e is arranged on an output shaft of a valve motor 9d, the valve motor 9d is arranged on an adjustable supporting frame 9c, and the adjustable supporting frame 9c is fixed on the upper shell 9 a; an upper valve chain wheel II 9j is installed at the rear end of the upper valve rotating shaft 9h1, the upper valve chain wheel II 9j is connected with a lower valve chain wheel 9n through a chain II 9k, the lower valve chain wheel 9n is installed at the rear end of the lower valve rotating shaft 9p1, the number of teeth of the lower valve chain wheel 9n is less than that of the upper valve chain wheel II 9j, and a speed measuring signal disc 9q is installed at the front end of the lower valve rotating shaft 9p1.

The tension degree of the first chain 9f can be adjusted through the adjustable supporting frame 9c, and a tension chain wheel 9m is arranged on the loose edge of the second chain 9 k; the valve motor 9d drives the upper valve chain wheel I9 g to rotate through the main chain wheel 9e and the chain I9 f, the upper valve chain wheel I9 g drives the upper rotary valve 9h to rotate through the upper valve rotating shaft 9h1, the upper valve chain wheel II 9j drives the lower valve chain wheel 9n to rotate through the chain II 9k, the lower valve chain wheel 9n drives the lower rotary valve 9p to rotate through the lower valve rotating shaft 9p1, the rotating speed of the lower rotary valve 9p is always greater than that of the upper rotary valve 9j, the two rotary valves are driven by the same valve motor 9d, but the discharging amount of the lower rotary valve 9p is always greater than that of the upper rotary valve 9h, and the inner cavities of the double rotary valves 9 are prevented from being blocked; the double rotary valve 9 can ensure the sealing performance of the horizontal sterilizer, and meanwhile, when downstream equipment is connected with gas for conveying, compatibility can be well realized. The signal panel 9q that tests the speed is convenient for provide the signal to speed sensor, prevents down rotary valve 9p and stops the action after, and the control room can not in time know, leads to last rotary valve 9h still unloading, causes the valve internal volume to press stifled die.

Taking 5000 tons/day soybean production line as an example, the content of organic impurities is about 0.25 percent, namely 12.5 tons/day, if the soybean meal is sterilized and added into the soybean meal for sale, the price of the soybean meal is 2800 yuan/ton, namely 35,000 yuan/day can be increased, if the soybean meal is produced for 300 days in a year, the annual income is increased by 10,500,000 yuan/year, and under the market environment with intense competition, the income brought by the organic impurities is still very considerable.
