Description

Technical Field

[0001] The utility model relates to the technical field of organic slurry processing, in particular to an organic slurry pneumatic conveying system. Background Art

[0002] Organic slurry refers to the slurry formed by processing recycled kitchen waste and agricultural and forestry organic waste; during the anaerobic fermentation of organic slurry, all materials need to be pre-treated by screening, crushing, pulping, sand removal, and impurity removal in accordance with anaerobic requirements, and each process cannot be completed by one device. Therefore, in the process of processing organic slurry, the organic slurry needs to be transferred between various devices.

[0003] Chinese Patent Publication No. CN 215138798 U discloses a slurry conveying system, comprising a bracket, a stirring box provided on the bracket, an upper cover provided at the upper end of the stirring box, a stirring shaft connected to the stirring box, and a motor connected to the side wall of the stirring box, a discharge port provided on the bottom surface of the stirring box, a discharge valve provided below the discharge port, a filter connected below the discharge valve, a rotating cover provided at the upper end of the filter, a feed port provided on the rotating cover, and a discharge port provided at an end of the filter away from the rotating cover, a filter element provided inside the filter, and a pneumatic diaphragm pump provided below the stirring box, a reinforcing rod connected to the lower end of the bracket, a mounting plate provided on the reinforcing rod, a spiral rod provided on the mounting plate, and a spring provided at the end of the spiral rod close to the filter;

[0004] The above-mentioned slurry conveying system utilizes a stirring shaft to drive the slurry to move, allowing the slurry to be discharged from the mixing box through the discharge port; however, the organic slurry is in a paste-like state, has poor fluidity and has viscosity for movement, so using a stirring shaft to drive the slurry and allowing the slurry to move in the discharge port using its own fluidity will make the slurry movement speed very slow, thereby making the slurry transportation speed low. In addition, the discharge port of the above-mentioned slurry conveying system is also provided with a discharge valve, a filter and other components, and the filter is provided with a filter element, which further reduces the movement speed of the slurry. When moving, the slurry will also adhere to the inner wall of the filter and the discharge valve, which can easily cause the filter and the discharge valve to be blocked, affecting the normal progress of the slurry transportation work.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-12 In the embodiment of the present invention, the pneumatic conveying system for organic slurry includes a storage hopper 1, the bottom of which is fixedly connected to the top of a feeding mechanism 2; the bottom of the feeding mechanism 2 is fixedly connected to the top of one end of a transport component 4, and the transport component 4 is fixedly connected to an air compressor 3 at one end close to the feeding mechanism 2, and the other end is fixedly connected to a storage tank 5;

[0033] The feeding mechanism 2 includes a connecting pipe 21, the bottom of which is welded to the top of a housing 22, and the connecting pipe 21 is in communication with the interior of the housing 22; a transmission shaft 25 is provided inside the housing 22, and the transmission shaft 25 is coaxially arranged with the housing 22; a plurality of partitions 26 are evenly welded on the transmission shaft 25, and a space is formed between the plurality of partitions 26 for temporarily storing the organic slurry;

[0034] The ends of the transmission shaft 25 are rotatably connected to the ends of the housing 22 through bearing seats 24, and one end of the transmission shaft 25 extends to the outside of the housing 22 and is fixedly connected to the output shaft of the motor 23. The motor 23 is fixedly connected to the outside of one end of the housing 22. A connection port is provided at the bottom of the housing 22, and a plurality of partitions 26 are in contact with the inner wall of the housing 22 on the side away from the transmission shaft 25.

[0035] The storage hopper 1 includes a storage hopper body 11, the bottom of which is fixedly connected to the top of the connecting pipe 21 by bolts; a filter screen 12 is fixedly connected to the inner side of the upper end of the storage hopper body 11, and a plurality of filter holes are evenly arranged on the filter screen 12; and a plurality of brackets 13 are fixedly connected to the outer sides of both ends of the storage hopper body 11 by bolts.

[0036] By adopting the above technical solution, the slurry is first put into the storage hopper body 11, and the filter screen 12 will filter the slurry in the storage hopper body 11, and filter out large-volume impurities mixed in the slurry, to prevent the impurities from following the slurry into the feeding mechanism 2 and clogging the feeding mechanism 2; after passing through the filter screen 12, the slurry moves to the bottom of the storage hopper body 11; the motor 23 drives the transmission shaft 25 to rotate, and the transmission shaft 25 simultaneously drives the multiple partitions 26 to rotate. When the space for temporarily storing the slurry between the two adjacent partitions 26 moves to just below the connecting pipe 21, the slurry in the storage hopper body 11 will flow into the space between the two adjacent partitions 26 through the connecting pipe 21; the side of the multiple partitions 26 away from the transmission shaft 25 is all in contact with the inner wall of the connecting pipe 21, so that the space between the two adjacent partitions 26 forms a closed space, and the slurry in this space will move synchronously with the space and will not leak to the outside of the space, thereby preventing the slurry from leaking out and clogging the outer shell 22.

[0037] In this embodiment, the material transport assembly 4 includes a material transport pipe 41. A feed port 45 is provided at the top of one end of the material transport pipe 41 close to the housing 22. The top of the feed port 45 is fixedly connected to the connection port at the bottom of the housing 22 by bolts. The end of the material transport pipe 41 close to the feed port 45 is fixedly connected to the output end of the air compressor 3.

[0038] The material transport pipe 41 is horizontally arranged at one end close to the storage hopper body 11, and is inclined at one end close to the storage tank 5, and extends above the storage tank 5. A plurality of support sleeves 42 are sleeved on the outside of the material transport pipe 41, and vertical frames 43 are welded to the bottom of each of the support sleeves 42. The bottoms of the vertical frames 43 are welded to the middle of the top of the bottom plate 44.

[0039] The storage tank 5 includes a tank body 51, a sealing interface 53 is provided on one side of the top of the tank body 51, and the end of the material delivery pipe 41 away from the air compressor 3 is fixedly connected to the sealing interface 53; an air outlet window 54 is provided on the side of the top of the tank body 51 away from the sealing interface 53; and a plurality of support frames 52 are evenly fixedly connected to the outer side of the lower end of the tank body 51 by bolts.

[0040] By adopting the above technical solution, when the space between two adjacent partitions 26 is full of slurry and moves to the bottom position of the outer shell 22, the slurry in this space will flow into the material transport pipe 41 through the connecting port at the bottom of the outer shell 22. The multiple partitions 26 rotate at a uniform speed, and the volume of the multiple spaces is the same, so that the slurry entering the material transport pipe 41 each time is the same, which can prevent the material transport pipe 41 from being blocked by too much slurry entering the material transport pipe 41 at one time; the air compressor 3 compresses the external space and allows compressed air to enter the material transport pipe 41. The slurry in the material transport pipe 41 moves rapidly toward the tank body 51 and into the inside of the tank body 51 under the strong pressure generated by the compressed air; an air outlet window 54 is provided on the top of the tank body 51. After the compressed air pushes the slurry into the inside of the tank body 51, it can be discharged from the tank body 51 through the air outlet window 54, thereby preventing the compressed air from accumulating in the tank body 51, so that the pressure inside the tank body 51 will not be greater than the pressure in the material transport pipe 41, ensuring that the slurry in the material transport pipe 41 can move normally into the tank body 51.

[0041] The working principle of the present invention is as follows: first, the slurry is put into the storage hopper body 11, and the filter screen 12 will filter the slurry in the storage hopper body 11, and filter out the large-volume impurities mixed in the slurry, so as to prevent the impurities from following the slurry into the feeding mechanism 2 and clogging the feeding mechanism 2; after the slurry passes through the filter screen 12, it moves to the bottom of the storage hopper body 11; the motor 23 drives the transmission shaft 25 to rotate, and the transmission shaft 25 synchronously drives the multiple partitions 26 to rotate, and when the space for temporarily storing the slurry between the two adjacent partitions 26 moves to just below the connecting pipe 21, the slurry in the storage hopper body 11 will flow into the space between the two adjacent partitions 26 through the connecting pipe 21; the side of the multiple partitions 26 away from the transmission shaft 25 is all in contact with the inner wall of the connecting pipe 21, so that the space between the two adjacent partitions 26 forms a closed space, and the slurry in this space will move synchronously with the space and will not leak to the outside of the space, thereby preventing the slurry from leaking out and clogging the outer shell 22;

[0042] When the space between two adjacent partitions 26 is full of slurry and moves to the bottom position of the outer shell 22, the slurry in this space will flow into the material transport pipe 41 through the connecting port at the bottom of the outer shell 22. The multiple partitions 26 rotate at a uniform speed, and the volume of the multiple spaces is the same, so that the slurry entering the material transport pipe 41 each time is the same, which can prevent the material transport pipe 41 from being blocked by too much slurry entering the material transport pipe 41 at one time; the air compressor 3 compresses the external space and allows compressed air to enter the material transport pipe 41. The slurry in the material transport pipe 41 moves rapidly toward the tank body 51 and into the inside of the tank body 51 under the strong pressure generated by the compressed air; an air outlet window 54 is provided at the top of the tank body 51. After the compressed air pushes the slurry into the inside of the tank body 51, it can be discharged from the tank body 51 through the air outlet window 54, thereby preventing the compressed air from accumulating in the tank body 51, so that the pressure inside the tank body 51 will not be greater than the pressure in the material transport pipe 41, ensuring that the slurry in the material transport pipe 41 can move normally into the tank body 51.

[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
