[0001] The utility model relates to the technical field of solid-liquid mixing and separation equipment, in particular to a belt-type fruit and vegetable pressing device. Background Art

[0002] Discarded fruits and vegetables are usually disposed of as garbage, but if fruits and vegetables are treated as garbage and randomly piled up, they are prone to corruption and produce various pathogens, which not only affect the city appearance but also endanger people's health. Moreover, the permeate water produced by the stacking process of fruit and vegetable waste with high water content can dissolve heavy metals, organic matter and other harmful substances in other garbage, so that the concentration of harmful pollutants increases, causing pollution to the surrounding soil and groundwater. In addition, the random stacking of fruit and vegetable waste is prone to cause a local anaerobic environment inside. The acidification rate of fruit and vegetable waste is relatively fast, and its metabolism produces organic acids, sulfide oxygen, etc., which emit a foul odor and also affect the health and living comfort of residents. For the fruit and vegetable waste generated in the fruit and vegetable market, slightly rotten fruits and vegetables are not suitable for consumption, but these fruits and vegetables are indispensable green fodder for livestock breeding. However, since fresh fruits and vegetables are not conducive to transportation and long-term storage, and they have already shown slight decay, they are even more unfavorable for long-term transportation or storage. The best way is to dehydrate them, remove the water and retain the pulp as feed. This not only reduces the generation of waste and avoids waste, but also forms a unified treatment for this type of fruits and vegetables, which is also very beneficial to environmental protection.

[0022] like Figure 1 and Figure 2A belt-type fruit and vegetable squeezing device shown includes a frame 1, a lower conveyor belt 4, an upper squeezing belt 6 and a flat sweeping device 20. In this device, the frame 1 is welded with columns and corresponding cross bars and vertical bars to form a frame-like bracket. A lower conveyor belt 4 is arranged on the frame 1, and the lower conveyor belt 4 is a belt conveying device in which a motor drives the roller to rotate, thereby driving the chain belt to rotate. In order to squeeze and dehydrate the mixture, the upper squeezing belt 6 is arranged above one end of the lower conveyor belt 4. The upper squeezing belt 6 is essentially the same conveying device as the lower conveyor belt 4, and is a belt conveying device in which a motor drives the roller to rotate, thereby driving the chain belt to rotate. The upper squeezing belt 6 and the lower conveyor belt 4 are driven by a motor 22, and the motor 22 is arranged at the frame 1 and a shield 21 is arranged at the transmission connection for protection. When the device is set to press, an upper pressing roller 14 is set above the joint between the lower conveyor belt 4 and the upper pressing belt 6, and a lower pressing roller 13 is set below. The upper pressing roller 14 and the lower pressing roller 13 form a pair of relative pressing rollers to convey and press the slag between them. In actual use, the upper pressing roller 14 and the lower pressing roller 13 provide auxiliary extrusion force here. According to needs, they can be set as symmetrical pressing rollers that can adjust the pressing gap with each other, and a motor can be added to drive the two to rotate relative to each other. At this time, the equipment can already press the slag, but the slag water transported down is not flat on the lower conveyor belt 4. If it is not processed, although it can still be squeezed and dehydrated, the squeezing force at the higher accumulation and the lower accumulation is different, which makes the squeezing dehydration still have the common problem of extrusion dehydration-all materials are accumulated in the middle of the dehydration chamber, the accumulation thickness is large, and dehydration is inconvenient. Therefore, a leveling device 20 is provided at the other end of the lower conveyor belt 4 to level the accumulated slag, so that the slag can be leveled to the lower conveyor belt 4, thereby making the pressing uniform. Specifically, the leveling device 20 includes a slide rail 9, a screw slider mechanism 10, a connecting rod 11, and a leveling plowshare 12. The slide rail 9 is provided on the frame 1 and suspended above the lower conveyor belt 4. The slide rail 9 is slidably connected to the slider of the screw slider mechanism 10. A connecting rod 11 is provided below the slider. A leveling plowshare 12 is provided on the connecting rod 11. In this way, the motor drives the screw to rotate, thereby driving the slider to slide back and forth on the slide rail 9, and then driving the leveling plowshare 12 to level the slag pile that is higher than the set gap.

[0023] In another embodiment, since the lower conveyor belt 4 moves forward, at least two sweeping devices 20 are provided to avoid untimely sweeping.

[0024] In another embodiment, in order to avoid poor pressing effect, the upper pressing roller 14 and the lower pressing roller 13 are arranged in pairs, and at least two groups are arranged.

[0025] In another embodiment, in order to facilitate the adjustment of the tightness of the upper pressing belt 6, a tension adjustment mechanism 8 is provided. The tension adjustment mechanism 8 in this scheme includes a remote lever and a telescopic device for driving the remote lever to rock. The rocking arm is connected to the frame 1, one end of the telescopic device is connected to the frame 1, and the other end is connected to the rocking arm. A guide roller is provided on the rod, and the upper pressing belt 6 passes through the guide roller. The telescopic drive of the telescopic device drives the rocking arm to rock, thereby tightening or loosening the upper pressing belt 6.

[0026] In another embodiment, in order to facilitate the uniform collection of squeezed juice, the device is provided with a water collecting trough 3 below the lower conveyor belt 4, and a water pipe 19 is provided on one side of the water collecting trough 3, so that the squeezed juice is uniformly collected and not easily splashed.

[0027] In another embodiment, the material actually contains the most water when it is being transported. At this time, the material is already flowing with juice without being pressed. In order to facilitate the discharge of the juice, the device sets the conveyor belt of the lower conveyor belt 4 to be a metal mesh belt 5 to facilitate the juice to flow out of the mesh holes, and sets the conveyor belt of the upper pressing belt 6 to be a block-shaped metal belt 7, that is, a chain conveyor belt.

[0028] The working process of the utility model is as follows:

[0029] The material falls from one side to one end of the lower conveyor belt 4, and then is transported forward with the movement of the lower conveyor belt 4. When it is transported to the leveling device 20, it is flattened on the lower conveyor belt 4 by the leveling device 20, and then it is continuously squeezed and dehydrated when it is transported to the upper pressing roller 14 and the lower pressing roller 13, and finally falls from the other end to the filter residue conveyor belt 18 and is transported to the next process for processing. In the process of filter residue falling, in order to prevent the filter residue from sticking to the conveyor belt, the device is provided with an upper scraper 15 for scraping the upper pressing belt 6 and a lower scraper 16 for scraping the lower conveyor belt 4 at the roller on the discharging side, and guide plates 17 are provided on both sides of the filter residue conveyor belt at the dropping position so that the dropped filter residue can be located in the middle of the filter residue conveyor belt.
