[0021] Beneficial effects of the utility model:

[0022] 1. The utility model is capable of drying sludge with different moisture contents simultaneously by designing a drying mechanism, namely a hot air blower, several conveying components and several sealing covers. Since the time required for drying and solidifying sludge with different moisture contents is different, the sealing cover is made of high-temperature resistant glass material, which allows for quick observation after the sludge is dried, thereby facilitating the synchronous drying of sludge with different moisture contents. By designing a solenoid valve on the outer wall of each dispersion pipe, when the sealing cover finds that the sludge in a covered placement tank is dried and solidified, the solenoid valve on the dispersion pipe connected to the sealing cover is immediately closed to prevent continued delivery of hot air from affecting the drying effect, thereby facilitating control of the drying and solidification degree of sludge with different moisture contents and facilitating subsequent cutting.

[0024] 3. The utility model designs placement troughs, and a number of drain holes are arranged at equal intervals inside each placement trough. An ultrafiltration membrane is laid on the inner bottom of each placement trough. When hot air is blown on the sludge, the hot air dries the moisture in the sludge, and the moisture passes through the ultrafiltration membrane and flows out from the several drain holes to the outside of the placement trough. The ultrafiltration membrane facilitates the outflow of moisture and can prevent the sludge from falling into the drain holes and affecting the solidification and molding effect, thereby facilitating subsequent cutting.

[0025] 4. The utility model is designed with a first electric push rod, a first push rod, an insert rod, a strip baffle, a connecting rod, a second push rod, a second electric push rod, an angled plate and a feeding slide. After drying and solidifying sludge with various moisture contents, the sludge can be automatically pushed out and cut off at a quarter of its own length, thereby achieving synchronous cutting. The sludge is then transported to the inside of several material chambers through several feeding slides. The crushing assembly is activated by the controller to achieve synchronous crushing of multiple excised block solidified sludges, without the need to cut and crush them one by one, thereby improving the drying and crushing effect of the sludge, facilitating and quickly carrying out detection work, and improving detection efficiency.

[0036] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0037] Reference Figures 1 to 7 As shown, the sludge drying and crushing processing device includes a base, which is horizontally arranged;

[0038] It also includes a controller, a drying mechanism, a cutting mechanism and a crushing mechanism;

[0039] The drying mechanism is located at the top of the base. The drying mechanism includes a hot air blower 1, several conveying components 2 and several sealing covers 3. The top of the base is provided with several placement slots 4 at equal intervals through several supporting legs. The hot air blower 1 is located at the top of the base. Each sealing cover 3 is sleeved on the top of a placement slot 4. The sealing cover 3 is made of high-temperature resistant glass material. After the sludge is dried, it is convenient to quickly observe it. Several conveying components 2 are fixed between the hot air blower 1 and the several sealing covers 3.

[0040] The cutting mechanism is arranged beside the plurality of placement slots 4. The cutting mechanism includes a cutter 5 and a drive assembly 6. The drive assembly 6 is arranged on the top of the base. The cutter 5 is slidably arranged beside the plurality of placement slots 4 through two guide rails.

[0041] The crushing mechanism is arranged at the top of the base. The crushing mechanism includes a crushing assembly 7 and several material chambers 8. The several material chambers 8 are fixed on the top of the base through two support plates and several connecting plates. The crushing assembly 7 is inserted into the several material chambers 8. The hot air blower 1, the driving assembly 6 and the crushing assembly 7 are all electrically connected to the controller.

[0042] Reference Figures 1 to 7 As shown, the conveying assembly 2 includes a circulation pipe 9, several conveying hoses 10, several dispersion pipes 11 and several air guide covers 12. The circulation pipe 9 is fixedly arranged on the output end of the hot air blower 1. The top of each sealing cover 3 is provided with an air inlet, each air guide cover 12 is fixedly arranged on the top of an air inlet, each dispersion pipe 11 is fixedly arranged on the top of an air guide cover 12, and each conveying hose 10 is fixedly arranged between the top of the circulation pipe 9 and a dispersion pipe 11. When several sealing covers 3 cover several discharge troughs, the hot air blower 1 is started by the controller, so that the hot air passes through the circulation pipe 9, several conveying hoses 10, several dispersion pipes 11 and several air guide covers 12 in turn into the interior of several sealing covers 3, blowing hot air to the sludge.

[0043] Reference Figures 1 to 7 As shown, a number of drain holes 13 are evenly spaced inside each placement trough 4, and an ultrafiltration membrane 14 is laid on the inner bottom of each placement trough 4. When hot air is blown on the sludge, the hot air dries the moisture in the sludge, and the moisture passes through the ultrafiltration membrane 14 and flows out from the several drain holes 13 to the outside of the placement trough 4. The ultrafiltration membrane 14 facilitates the outflow of moisture and prevents the sludge from falling into the drain holes 13. It should be noted that a solenoid valve is fixed on the outer wall of the upper half of each dispersion pipe 11. When the sealing cover 3 finds that the sludge in a placement trough 4 covered by the sealing cover 3 is dried and solidified, the solenoid valve on the dispersion pipe 11 connected to the sealing cover 3 is immediately closed to prevent the continued delivery of hot air from affecting the drying effect and causing inaccurate subsequent sludge monitoring.

[0044] Reference Figures 1 to 7As shown, two first cylinders 15 are fixedly provided on the top of the base, two lifting plates 16 are fixedly provided on the top of several sealing covers 3, and two push plates 17 are fixedly provided between the two lifting plates 16. The output end of each first cylinder 15 is fixedly connected to the bottom of a push plate 17, and each first cylinder 15 is electrically connected to the controller. When the sludge drying and crushing work is carried out, first, sludge with different moisture contents is taken and placed into several placement tanks 4 respectively, and the placement tanks 4 are filled, and the sampling weight is 1 kg. Then the two first cylinders 15 are started by the controller, so that their output ends drive the two push plates 17 to descend. Since the two lifting plates 16 are fixedly connected to several sealing covers 3, the two lifting plates 16 are fixedly connected to the two push plates 17, the output end of each first cylinder 15 is fixedly connected to the bottom of a push plate 17, and then the three sealing covers 3 are driven to descend until each sealing cover 3 covers a discharge trough, which can effectively prevent dust from entering the sludge during drying and affecting the sludge monitoring work after drying.

[0045] Reference Figures 1 to 7 As shown, the crushing assembly 7 includes a motor 18, a rotating shaft 19 and several crushing rollers 20. The rotating shaft 19 is rotatably arranged between two support plates. Each crushing roller 20 is fixed on the rotating shaft 19. The motor 18 is fixed on the outer wall of one of the support plates, and its output end is fixedly connected to one end of the rotating shaft 19. The motor 18 is electrically connected to the controller. When the block parts cut from a variety of dried and solidified sludges fall from the feeding chute 31 into the interior of several material cavities 8, the motor 18 is started by the controller, thereby driving the several crushing rollers 20 to rotate inside the several material cavities 8 through the rotating shaft 19, crushing the fallen block sludge to achieve crushing.

[0046] Reference Figures 1 to 7 As shown, the driving assembly 6 includes two second cylinders 21 and two pulling blocks 22. The two second cylinders 21 are fixed on the top of the base, and each pulling block 22 is fixed between one end of the top of the cutter 5 and the output end of a second cylinder 21. Each second cylinder 21 is electrically connected to the controller. When a quarter of the length of several dried and solidified sludges is pushed out from the push-out port to the bottom of the cutter 5, the two second cylinders 21 are started by the controller to shrink their output ends, thereby driving the cutter 5 to slide down between the two guide rails through the two pulling blocks 22 to cut a quarter of the several dried and solidified sludges.

[0047] Reference Figures 1 to 7As shown, a first electric push rod 23 is fixed on the outer wall of one end of one of the supporting legs, and a plurality of plug rods 25 are fixed on its output end through a first push rod 24, and an end of each plug rod 25 away from the first push rod 24 is plugged into one end of a placement slot 4, and an end of each placement slot 4 away from the plug rod 25 is provided with a push-out port, and a strip baffle 26 is fitted on each push-out port, and the top of each placement slot 4 is provided with a through slot for the strip baffle 26 to pass through, and two slide rails are fixed to the bottom of each through slot, and each strip baffle 26 is slidably connected to the two slide rails, and a connecting rod 27 is fixed to the bottom of each strip baffle 26, and a second push rod 28 is fixed to the bottom of a plurality of connecting rods 27, and a second electric push rod 29 is fixed to the outer wall of the other end of one of the supporting legs, and its output end is fixedly connected to the bottom of the second push rod 28, and the first electric push rod 23 and the second electric push rod 29 are both electrically connected to the controller. When a plurality of placement slots 4 are placed, After the sludge inside is dried and solidified, the output ends of the two first cylinders 15 are extended through the controller, thereby driving the several sealing covers 3 to rise through the two push plates 17 and the two lifting plates 16, so that the strip baffles 26 are not blocked by the sealing covers 3, and then the second electric push rod 29 is started by the controller to retract its output end, thereby driving the several strip baffles 26 through the several through slots and sliding down to the inside of the six slide rails through the second push rod 28 and the several connecting rods 27, and then the first electric push rod 23 is started by the controller to make its output end extend toward one end close to the placement groove 4, thereby driving the first push rod 24 and the several insertion rods 25 through its output end to push the dried and solidified sludge in the several placement grooves 4 toward the push-out port, and the pushing stroke is a quarter of the length of the placement groove 4. Since the sludge initially fills the placement groove 4, a quarter of the length of the several dried and solidified sludge is pushed out from the push-out port to the bottom of the cutter 5.

[0048] Reference Figures 1 to 7 As shown, each placement slot 4 is provided with an angled angle 30 at one end away from the first electric push rod 23, and a feeding chute 31 is fixedly provided between each angled angle 30 and the top of a material chamber 8. The bottom of each material chamber 8 is provided with an arc-shaped discharge port, and an arc-shaped baffle 32 is inserted between several arc-shaped discharge ports. One end of the arc-shaped baffle 32 is inserted into one of the support plates, and the other end of the arc-shaped baffle 32 passes through the other support plate. After a quarter of several dried and solidified sludges are cut off, under the action of the angled angle 30, the cut block parts fall from the feeding chute 31 into the interior of several material chambers 8. After crushing, the arc-shaped baffle 32 is pulled out from between the two support plates, so that several arc-shaped discharge ports are opened. The monitoring personnel can use a container to receive the crushed sludge falling from the three arc-shaped discharge ports, which is convenient for subsequent detection.
