DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, in the embodiment of the present invention, a self-turning sludge constant temperature treatment equipment comprises a support frame, which comprises a support bottom plate 2 and a support vertical plate 1; a heating cylinder 3, one side of which is rotatably connected to the support vertical plate 1 through a connecting plate 301, and the support vertical plate 1 is provided with a driving member for driving the heating cylinder 3 to rotate; a rotary cover 7, which is rotatably connected to the inside of the heating cylinder 3, and a plurality of lifting plates 701 are provided on the arc-shaped inner wall of the rotary cover 7, and a rotary cylinder 13 is coaxially mounted on the end center of the rotary cover 7, and the rotary cylinder 13 is rotatably connected to the connecting hole opened on one end surface of the heating cylinder 3, and is driven to rotate by a rotary assembly 14 on the outside of the heating cylinder 3, and the rotary assembly 14 is installed in a power box 17 on the outside of the heating cylinder 3; a crushing box 8, which is arranged in the heating cylinder 3 and is slidably connected to the inner wall of the end side of the heating cylinder 3 in the horizontal direction, and a mud guide groove 9 is provided on the upper side of the crushing box 8, and a plurality of groups of A vertical material guide channel, on the inner wall of which multiple groups of particle boards 801 are fixedly installed; a reciprocating structure for driving the particle box 8 to move back and forth, comprising a transmission shaft 15, a planetary gear set 20 and a transmission assembly 16, wherein one end of the transmission shaft 15 is rotationally connected to the power box 17, and the other end is transmission-connected to the particle box 8 through the transmission assembly 16, wherein the planetary gear set 20 comprises a transmission gear ring 202, a first transmission gear 201 and a second transmission gear 203, wherein the transmission gear ring 202 is coaxially mounted inside the rotary drum 13, multiple groups of the first transmission gears 201 are uniformly rotationally mounted inside the rotary drum 13 along the circumference of the rotary drum 13, the second transmission gear 203 is coaxially mounted on the transmission shaft 15, and the first transmission gear 201 is meshed with the transmission gear ring 202 and the second transmission gear 203 on both sides, and the particle box 8 is driven to move back and forth by the rotation transmission of the rotary drum 13;

[0027] Specifically, in the present invention, while the heating cylinder 3 is heating the sludge therein at a constant temperature, the rotating assembly 14 outside the heating cylinder 3 drives the rotating cylinder 13 and the rotating cover 7 to rotate, wherein when the rotating cover 7 rotates, the lifting plate 701 on the arc-shaped inner wall thereof transports the sludge to a high place, and at the same time, the sludge at a high place slides down under the action of gravity, and is guided by the sludge guide groove 9 to be collected in the crushing box 8;

[0028] When the rotary drum 13 rotates, the planetary gear set 20 in the reciprocating structure drives the transmission shaft 15 to rotate, and when the transmission shaft 15 rotates, the transmission assembly 16 drives the crusher box 8 to reciprocate in the horizontal direction, so that the sludge in the crusher box 8 is transported downward along the corresponding material guide channel and collides with the crusher board on the inner wall of the material guide channel, thereby breaking the sludge agglomerates.

[0029] like Figure 1 , Figure 2 as well as Figure 5As shown, in the embodiment of the present invention, the transmission assembly 16 includes a rotating disk 161 and a limiting frame 163. The rotating disk 161 is coaxially mounted on the end of the transmission shaft 15. The rotating disk 161 is eccentrically fixedly mounted on the limiting column 162. The limiting frame 163 is fixedly mounted on the side of the crushing box 8 and is provided with a limiting vertical groove for the limiting column 162 to be slidably connected.

[0030] Specifically, when the reciprocating structure of the present invention is reciprocatingly driven, the rotary drum 13 is driven to rotate by the rotary assembly 14, and the gear transmission of the plurality of first transmission gears 201 drives the second transmission gear 203 to rotate, and drives the transmission shaft 15 to transmit, wherein the transmission shaft 15 drives the rotary disk 161 at its end to rotate when rotating, so that the eccentrically mounted limiting column 162 on the rotary disk 161 corresponds to the circular motion and slides along the limiting vertical slot in the limiting frame 163. Since the limiting vertical slot is fixedly connected to the crushing box 8, the limiting vertical slot can only reciprocate in the horizontal direction to realize the crushing operation;

[0031] It should be noted that, in the preferred embodiment of the present invention, the radial specification of the first transmission gear 201 is greater than the radial specification of the second transmission gear 203, so that the rotation speed of the transmission shaft 15 is greater than the rotation speed of the rotary drum 13, thereby meeting the speed requirement of the reciprocating movement of the crushing box 8 and ensuring the crushing capacity of the crushing box 8;

[0032] Of course, in actual design, the transmission assembly 16 may also be made of other components with reciprocating driving capabilities, such as a turntable connecting rod structure, etc. The present invention does not make a rigid requirement for the transmission assembly 16.

[0033] like Figure 1 As shown, in the embodiment of the present invention, the driving member is a driving cylinder 6, and a group of connecting seats 601 are respectively installed at the mounting end and the telescopic end of the driving cylinder 6, and the two groups of connecting seats 601 are respectively hinged to the supporting vertical plate 1 and the side of the heating cylinder 3. In the present invention, the heating cylinder 3 is rotated by the telescopic movement of the driving cylinder 6 to switch the sludge feeding and discharging states;

[0034] Furthermore, the upper and lower ends of the heating cylinder 3, which are different from the side where the rotary cylinder 13 is installed, are respectively provided with a feed port and a discharge port, and a feed pipe 4 and a sealing door 5 are respectively installed at the feed port and the discharge port. Of course, the feed pipe 4 and the sealing door 5 are designed to be fixed with a corresponding fixed structure, and the fixed structure can preferably be a fixed buckle, etc.;

[0035] In the present invention, when the sludge is loaded and heated at a constant temperature, the driving cylinder 6 is extended and retracted to drive the heating cylinder 3 to rotate to a vertical state. When the dried sludge is unloaded, the driving cylinder 6 is extended to drive the heating cylinder 3 to an inclined state. At this time, the sealing door 5 at the bottom of the heating cylinder 3 is opened, so that the sludge in the heating cylinder 3 can slide out by gravity.

[0036] A collecting trough 18 is provided at the bottom of the supporting bottom plate 2 . The collecting trough 18 is placed at the bottom of the sealing door 5 . The sludge that slides out is collected through the collecting trough 18 .

[0037] like Figure 1 As shown, in the embodiment of the present invention, a plurality of groups of positioning transverse tubes 12 are installed on the side of the crushing box 8 away from the reciprocating structure, and the positioning transverse tubes 12 are correspondingly slidably connected with a plurality of groups of positioning columns 10 fixedly installed on the inner wall of the heating cylinder 3, and the end sides of the plurality of groups of positioning columns 10 are fixedly connected with the fixing plates 11 in the heating cylinder 3;

[0038] In the present invention, three groups of positioning transverse tubes 12 are provided on the side of the crushing box 8 in the vertical direction. The three groups of positioning transverse tubes 12 are slidably connected with the corresponding three groups of positioning columns 10 . The present invention does not make specific requirements on the number of positioning transverse tubes 12 and positioning columns 10 .

[0039] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the rotating assembly 14 includes a fixed ring gear 141 and a driving gear 142, and the fixed ring gear 141 is coaxially fixed on the outer side of the rotating drum 13, and the driving gear 142 is driven to rotate by the driving motor 19 on the processing box, and meshes with the fixed ring gear 141 for transmission. In the present invention, the driving motor 19 drives the driving gear 142 to rotate, thereby driving the fixed ring gear 141 and the rotating drum 13 to rotate synchronously. Of course, in actual design, the fixed ring gear 141 and the driving gear 142 can also be replaced by other components with rotation transmission capabilities, such as a belt drive connection method, etc. When a belt connection is selected, the fixed ring gear 141 and the driving gear 142 are correspondingly replaced by a transmission wheel for transmitting the connecting belt.

[0040] In summary, the advantages of the present invention are:

[0041] 1. By designing a support frame, a heating cylinder 3, a rotary cover 7, a crushing box 8 and a reciprocating structure, the heating cylinder 3 is rotatably mounted on the support frame, and the heating cylinder 3 is driven to rotate to realize the rotation of the heating cylinder 3. A plurality of lifting plates 701 are arranged on the arc-shaped inner wall of the rotary cover 7. The rotary cover 7 rotates to transport the sludge in the heating cylinder 3 upward and pour it into the crushing box 8. The reciprocating assembly drives the crushing box 8 to move back and forth horizontally to realize the crushing operation. This solves the current problem that when the sludge is heated and dried, the temperature difference between the outside and inside of the sludge is large, the sludge surface is dried before the inside of the sludge, and the long-term heating operation causes the sludge surface to agglomerate, which affects the constant temperature drying effect;

[0042] 2. The radial specification of the first transmission gear 201 in the planetary gear set 20 is designed to be larger than the radial specification of the second transmission gear 203, so that the rotation speed of the transmission shaft 15 is greater than the rotation speed of the rotary drum 13, thereby meeting the speed requirement of the reciprocating movement of the crushing box 8 and ensuring the crushing capacity of the crushing box 8.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
