[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0031] See also Figure 1-8This embodiment provides the following technical solutions: a mud separation conveyor, comprising a screening box 1 and a chain conveyor 2 fixedly arranged in the screening box 1, the screening box 1 is provided with a driving device for driving the chain conveyor 2 to transport mud, and the driving device can enable the chain conveyor 2 to circulate and transport the mud entering the screening box 1.
[0032] In some embodiments, the screening box 1 is tilted to facilitate screening of the mud.
[0033] Screening holes 3: a plurality of distributed screening holes 3 are arranged at intervals on the chain plate body of the chain plate conveyor 2. Through the screening holes 3, larger mud blocks in the mud can be separated before the mud is processed. In the process of conveying the mud by the chain plate conveyor 2, larger mud blocks can be left on the chain plate, while smaller mud blocks can fall from the chain plate along the screening holes 3, thereby separating the larger mud blocks from the smaller mud blocks in the mud.
[0034] The first row of hoppers 4 is located below the unloading end of the chain conveyor 2. The first row of hoppers 4 can be used to collect larger mud blocks on the chain.
[0035] The second row of hoppers 5 is arranged on the right side of the first row of hoppers 4. The second row of hoppers 5 can be used to collect smaller mud blocks on the chain plate.
[0036] The drainage plate 6 is arranged between the upper chain plate and the lower chain plate of the chain conveyor 2, and the drainage plate 6 is fixedly connected to the screening box 1; through the drainage plate 6, the smaller mud blocks passing through the screening holes 3 can be drained, so that the smaller mud blocks can enter the next-level screening equipment through the second row hopper 5, and the smaller mud blocks flowing out from the upper part of the chain plate are prevented from falling on the lower chain plate, thereby increasing the treatment effect of the mud treatment equipment on the mud and being able to reasonably utilize waste resources.
[0037] A mud pump is fixedly installed on the screening box 1, and the discharge end of the mud pump is connected to a mud pipe 7. The discharge end of the mud pipe 7 extends to the inside of the screening box 1 and is arranged above the feed end of the chain conveyor 2. Through the mud pump and the mud pipe 7, the mud to be processed can be transported to the inside of the screening box 1.
[0038] The guide plate 6 is arranged along the conveying direction of the chain conveyor 2, and both ends of the guide plate 6 are inclined downward and extend to the outside of the chain conveyor 2. Both ends of the guide plate 6 are also fixedly connected with extension plates. The end of the guide plate 6 adjacent to the feeding end of the chain conveyor 2 is fixedly provided with a baffle plate 8. In some embodiments, the baffle plate 8 is arranged at the right end of the guide plate 6. Through the guide plate 6 and the extension plate, smaller mud blocks flowing out of the screening hole 3 can be drained to prevent the smaller mud blocks from flowing onto the chain plate below. Through the baffle plate 8, the smaller mud blocks can be better made to fall on the guide plate 6.
[0039] As shown in the figure, the vertical section of the guide plate 6 is an inverted "V"-shaped structure.
[0040] The second row hopper 5 is a conical structure, and a discharge port is provided at the bottom of the second row hopper 5, which can better drain smaller mud blocks and facilitate the discharge of smaller mud blocks from the discharge port.
[0041] It includes a first cleaning mechanism 9 arranged above both sides of the second row hopper 5, which is used to clean the second row hopper 5. The first cleaning mechanism 9 includes a first water spray pipe 91 fixedly arranged on the second row hopper 5 and a first high-pressure pump fixedly arranged on the screening box 1. The first water spray pipe 91 is connected to the first high-pressure pump.

In some embodiments, the first water spray nozzle 92 on the left is parallel to the inner wall of the left side of the second row hopper 5, and the first water spray nozzle 92 on the right is parallel to the inner wall of the right side of the second row hopper 5. Through the first high-pressure pump, the first water spray pipe 91 and the first water spray nozzle 92, smaller mud blocks falling on the inner wall of the second row hopper 5 can be flushed, so that the smaller mud blocks can better enter the discharge port, thereby preventing the smaller mud blocks from adhering to the inner wall of the second row hopper 5, causing inconvenience for workers to clean.
[0042] It also includes a second cleaning mechanism 10 arranged above the second row hopper 5, which is used to clean the chain plates on the chain conveyor 2. The second cleaning mechanism 10 includes a support frame 101 and a cleaning roller 102 rotatably arranged on the support frame 101. The screening box 1 is provided with a motor for driving the cleaning roller 102 to rotate. The motor is controlled to rotate the cleaning roller 102, so that the chain plates on the chain conveyor 2 can be cleaned during the conveying process of the chain conveyor 2, avoiding long-term screening of mud blocks, which may cause the screening holes 3 on the chain plates to be blocked, and also avoiding a large amount of impurities from adhering to the chain plates.
[0043] A second water spray pipe 103 is fixedly arranged on both sides of the cleaning roller 102 on the support frame 101, and a plurality of second water spray nozzles 104 facing the chain conveyor 2 are connected to the second water spray pipe 103; a second high-pressure pump, the second high-pressure pump is fixedly arranged on the screening box 1, and a water supply pipe is connected to the second high-pressure pump, and the water supply pipe is connected to the second water spray pipe 103. Through the second high-pressure pump, the second water spray pipe 103 and the second water spray nozzle 104, the chain can be further cleaned, and the screening hole 3 can also be flushed.
[0044] The support frame 101 is a hollow structure, and the bottom of the support frame 101 is fixed on the second row hopper 5 through a support rod 105. Through the support frame 101, the cleaned mud blocks can fall onto the second row hopper 5.
[0045] The working principle of the utility model is as follows: through the control device, the driving device is operated to make the chain conveyor 2 work, the mud pump is controlled, and the mud enters the screening box 1 through the mud pipe 7, and when the chain conveyor 2 is working, the mud falling on the chain plate is transported, and at the same time, the larger mud blocks follow the chain plate to move until they fall from the left end of the chain conveyor 2 into the first row hopper 4, and the large mud blocks can be transported with the help of the transportation equipment;
[0046] During the conveying process of the chain conveyor 2, smaller mud blocks will fall onto the drainage plate 6 along the screening holes 3, and then fall into the second row hopper 5 after being drained by the drainage plate 6, so that the smaller mud blocks are collected;
[0047] Control the first high-pressure pump to allow external water to enter the first water nozzle 92 through the first water spray pipe 91, so that the first water spray nozzle 92 can wash the smaller mud blocks on the left and right inner walls of the second row hopper 5, so that the smaller mud blocks on the left and right side walls of the second row hopper 5 can be gathered at the discharge port of the second row hopper 5, so as to facilitate the discharge of the second row hopper 5;
[0048] Control the second high-pressure pump to allow external water to enter the second water spray nozzle 104 through the second water spray pipe 103, so that the second water spray nozzle 104 washes the surface of the chain plate;
[0049] At the same time, the motor is controlled to make the cleaning roller 102 work, so as to clean the surface of the chain plate passing through the cleaning roller 102 .
