Telescopic rods are arranged on one side of the limit plate and the support plate, and the telescopic rods are rotatably connected to the limit plate, the support plate, the tank body and the partition frame.

[0014] Furthermore, the compression assembly also includes a support plate, a sliding hole, a return spring and a linkage plate.

[0016] The present invention provides a compression-type solid-liquid separation sewage suction truck, which has the following beneficial effects: when in use, solid waste can be initially compressed during solid-liquid separation, and can be automatically cleaned during the separation process to avoid blockage; after solid-liquid separation, solid waste can continue to be compressed for a second time, and after compression is completed, it can be transferred and stored, which is convenient for continued compression and unified discharge, and also convenient for cleaning the inside of the tank.

[0017] 1. When the present invention is in use, the vacuum pump extracts sewage and sends it into the inner cylinder. At this time, smaller solid garbage can leave the inner cylinder and the outer cylinder from the sieve holes together with the sewage, while larger solid garbage will remain in the inner cylinder. The motor drives the spiral rod to rotate inside the inner cylinder, so that the blades on the surface of the spiral rod squeeze the garbage, and while the garbage is initially compressed, the residual sewage is squeezed out of it for separation. When the spiral rod squeezes the garbage, the transmission component can apply force to the static tooth plate, so that the static tooth plate drives the outer cylinder to move outside the inner cylinder through the connecting rod, and squeezes the vibration spring, so that the outer cylinder is ordered to reciprocate on the inner cylinder under the elastic action of the vibration spring. When the outer cylinder moves, the sieve holes on the outer cylinder and the inner cylinder will be staggered with each other, and the relatively slender garbage remaining in the sieve holes will be sheared and reduced due to the misalignment of the sieve holes, so as to avoid the garbage blocking the sieve holes, resulting in the sewage being unable to be separated smoothly and overflowing. In summary, when in use, the sewage can be separated into solid and liquid and the solid garbage can be initially compressed, and the sieve holes can be avoided from being blocked by slender garbage.

[0018] 2. Before use, the present invention is installed on the tank body first. At this time, the end of the spiral rod away from the motor can be inserted into the slot, and the spiral rod can be engaged with the main shaft through the plug block and the slot, so that when the spiral rod rotates, the main shaft can follow the spiral rod to rotate synchronously through the plug block and the slot, and the sealing plate can seal the open end of the inner cylinder to prevent leakage of solid waste. When the spiral rod rotates, the movable tooth plate can be driven by the main shaft to rotate synchronously, so that the movable tooth plate exerts force on the static tooth plate through the tooth blocks staggered with the static tooth plate to move it. At the same time, the cam plate can also rotate synchronously with the main shaft to provide power for the compression component to perform secondary compression on the solid waste. After the sewage suction truck completes its work, it only needs to remove the cover plate from the tank body to separate the sealing plate from the inner cylinder. At this time, the inner cylinder can be cleaned by directly flushing it with water, and the cleaned waste water can also be directly mixed with sewage and wait for centralized discharge. In summary, when in use, the rotation of the spiral rod can drive other components to operate, without the need to set up an extra power source, and it is also convenient to clean the inner cylinder after completing the work.

[0019] 3. After the solid-liquid separation is completed, the solid waste is pushed to the discharge port by the spiral rod, and leaves the inner cylinder through the discharge port, slides along the guide plate to the support plate, and the cam plate can apply force to the linkage plate when following the rotation of the main shaft, so that the linkage plate compresses the reset spring and drives the pressure plate to descend through the slide bar, so as to perform secondary compression on the solid waste. Then the reset spring can drive the pressure plate to rise through the linkage plate, so as to continue to compress the subsequent falling waste. The support plate can limit the slide bar through the slider to avoid the deflection of the pressure plate during the movement. When the pressure on the pressure sensor reaches the predetermined value, it indicates that the garbage above the support plate has reached the compression limit. At this time, the lifting rod drives the pressure block to descend, fixes the position of the pressure plate, and avoids the subsequent The garbage continues to slide down, and at the same time, the telescopic rod drives the limit plate and the support plate to rotate, so that the compressed garbage slides into the partition frame, and then the telescopic rod drives the limit plate and the support plate to reset, and the lifting rod drives the pressure block to reset, and the pressure plate can rise under the action of the reset spring, and the garbage on the guide plate slides down to the support plate for compression again. After the sewage suction truck completes the work, open the unloading door, and the garbage in the partition frame and on the support plate can be unloaded for the next use. When removing the cover plate, the lifting rod can apply force to the pressure plate through the pressure block, so that it drives the linkage plate to descend through the sliding rod, so as to avoid the linkage plate from hindering the movement of the moving tooth plate. In summary, during use, the solid garbage can be compressed for a second time and transferred and stored after the compression is completed, which is convenient for continued compression and unified discharge.

[0030] The specific operation is as follows. When in use, the vacuum pump 4 extracts sewage and sends it into the inner cylinder 301. At this time, smaller solid garbage can leave the inner cylinder 301 and the outer cylinder 304 together with the sewage through the sieve hole 305, while the larger solid garbage will remain in the inner cylinder 301. The motor 6 drives the screw rod 5 to rotate inside the inner cylinder 301, so that the blades on the surface of the screw rod 5 squeeze the garbage. While the garbage is initially compressed, the residual sewage is squeezed out of it for separation. When the screw rod 5 squeezes the garbage, the transmission component 8 can apply force to the static tooth plate 307, so that the static tooth plate 307 drives the outer cylinder through the connecting rod 306.

At the same time, the cam plate 806 can also rotate synchronously with the main shaft 802 to provide power for the compression component 9 to perform secondary compression on the solid waste. After the sewage suction truck completes its work, it only needs to remove the cover plate 801 from the tank body 2 to separate the sealing plate 803 from the inner cylinder 301. At this time, the inner cylinder 301 can be cleaned by directly flushing it with water, and the cleaned waste water can also be directly mixed with sewage and wait for centralized discharge.

In summary, during use, the solid garbage can be compressed for a second time, and transferred and stored after the compression is completed, which is convenient for continued compression and unified discharge.

[0033] In summary, when the compression type solid-liquid separation sewage suction truck is used, the cover plate 801 is first installed on the tank body 2, and then the end of the screw rod 5 away from the motor 6 can be inserted into the slot 804, and the screw rod 5 can be engaged with the main shaft 802 through the plug block 7 and the slot 804, so that when the screw rod 5 rotates, the main shaft 802 can rotate synchronously with the screw rod 5 through the plug block 7 and the slot 804, and at the same time, the sealing plate 803 can seal the open end of the inner cylinder 301 to prevent solid waste from leaking. The vacuum pump 4 extracts sewage and sends it into the inner cylinder 301. At this time, smaller solid waste can leave the inner cylinder 301 and the outer cylinder 304 together with the sewage from the sieve hole 305, while the larger solid waste will remain in the inner cylinder 301, and the motor 6 drives the screw rod 5 to rotate inside the inner cylinder 301 The spiral rod 5 is moved, so that the blades on the surface of the spiral rod 5 squeeze the garbage, and while the garbage is compressed for the first time, the residual sewage is squeezed out of it for separation. When the spiral rod 5 squeezes the garbage, the main shaft 802 can drive the movable tooth plate 805 and the cam plate 806 to rotate synchronously, so that the movable tooth plate 805 exerts force on the static tooth plate 307 through the tooth blocks staggered with the static tooth plate 307 to move it, so that the static tooth plate 307 drives the outer cylinder 304 to move outside the inner cylinder 301 through the connecting rod 306, and squeezes the vibration spring 303, so that the outer cylinder 304 is reciprocated on the inner cylinder 301 under the elastic action of the vibration spring 303.

In summary, after the solid-liquid separation is completed, the solid garbage is pushed to the discharge port 308 by the spiral rod 5, and leaves the inner cylinder 301 through the discharge port 308, slides along the guide plate 902 to the support plate 905, and the cam plate 806 can apply force to the linkage plate 909 when rotating with the main shaft 802, so that the linkage plate 909 compresses the return spring 908 and drives the pressure plate 911 to descend through the slide rod 910, so as to perform secondary compression on the solid garbage, and then the return spring 908 can drive the pressure plate 911 to descend through the linkage plate 909 1 is rebounded, so as to continue to compress the subsequent garbage that falls, and the support plate 906 can limit the sliding rod 910 through the slider to prevent the pressure plate 911 from being deflected during the movement. When the pressure on the pressure sensor reaches a predetermined value, it means that the garbage above the support plate 905 has reached the compression limit. At this time, the lifting rod 912 drives the pressure block 913 to descend, fixes the position of the pressure plate 911, and prevents the subsequent garbage from continuing to slide. At the same time, the telescopic rod drives the limit plate 904 and the support plate 905 to rotate, so that the compressed garbage slides into the partition frame 901, and then the telescopic rod drives the limit plate 904 and the support plate 905 to reset, and the lifting rod 912 drives the pressure block 913 to reset, and the pressure plate 911 can rise again under the action of the reset spring 908.The garbage on the guide plate 902 slides down to the support plate 905 again for compression. After the suction truck finishes its work, it opens the unloading door 903 to unload the garbage in the partition frame 901 and on the support plate 905 for next use. When cleaning the inner cylinder, it is only necessary to remove the cover plate 801 from the tank body 2 to separate the sealing plate 803 from the inner cylinder 301. At this time, the inner cylinder 301 can be cleaned by directly flushing it, and the cleaned waste water can also be directly mixed with sewage and wait for centralized discharge.
