Description

Technical Field

[0001] The utility model relates to the technical field of garbage transportation, and is a pneumatic transportation device for dead branches and fallen leaves. Background Art

[0002] The food waste is collected by tank trucks and transported to the treatment plant, where it is dumped into a collection bin (collection hopper) for dry-wet separation. After the solid matter is broken, squeezed and dehydrated, the moisture content is about 70%. It is then transported to a mixer using a screw shaft, where dead branches and leaves are added. After mixing, it is transported to an aerobic composting device for composting treatment to produce organic fertilizer.

[0003] The humidity of materials for aerobic fermentation should not exceed 60%, otherwise anaerobic fermentation will occur locally due to water sealing and lack of oxygen supply; a temperature of 55-65℃ will lead to excessive consumption of N elements and the fertilizer may be nitrogen-deficient; the temperature is too low to kill E. coli and plant seeds; the C:N ratio of aerobic fermentation is 25-30:1; while dead branches and leaves have a high C content and too low N content, making them difficult to compost; food waste has high humidity and high salt content; the two can be treated together to complement each other, which can adjust the humidity, increase porosity, and the overall carbon-nitrogen ratio, and reduce salt concentration.

[0004] If the crushed dead branches and leaves are transported by carts, loaded, transported and dumped into the mixer hopper, the efficiency is low and there are problems such as scattering. If conveyor belts, screw shafts, etc. are used for transportation, it is difficult and energy-intensive because of the large distance, horizontal movement, small amount of height lifting, and the need to pass through roads. Summary of the Invention

[0005] The utility model provides a pneumatic conveying device for dead branches and fallen leaves, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problems of low efficiency, easy scattering and high energy consumption of the existing devices for transporting crushed dead branches and fallen leaves.

[0006] The technical solution of the present utility model is achieved through the following measures: a pneumatic conveying device for dead branches and fallen leaves, comprising a fan, a feed pipe, a connecting pipe, a hose and a barrel body with a barrel cover sealed on the upper end, a discharge port connected inside and outside and a discharge gate capable of opening and closing the discharge port are provided at the lower end of the barrel body, air outlet holes and air inlet holes connected inside and outside are provided at intervals on the upper outer side of the barrel body, a filter is installed on the inner side of the upper part of the barrel body at a position corresponding to the air inlet and the air outlet, the air outlet hole is fixedly connected to the air inlet of the fan, the air inlet hole is fixedly connected to the first end of the feed pipe, a plurality of connecting pipes are fixedly connected at intervals along the length direction of the feed pipe, and a hose is detachably installed on the second end of the feed pipe or / and the end of at least one connecting pipe.

[0007] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:

[0008] The above may also include a cart, which includes a bucket and wheels. There is a feed port on the right side of the bucket, an axle is installed on the left side of the lower part of the bucket, and wheels are rotatably installed at both ends of the axle. The right part of the hose is fixedly installed on the inner side of the left part of the bucket, and a handle is fixedly installed on the upper side of the left part of the bucket.

[0009] The end portion of the hose may have an inclined guide surface, and the distance between the guide surface and the inner side of the lower portion of the bucket gradually increases from left to right.

[0010] An air extraction pipe may be fixedly connected between the air outlet and the air inlet of the fan.

[0011] The lower portion of the barrel body corresponding to the position below the air inlet hole may gradually become thinner from top to bottom.

[0012] The utility model has a reasonable and compact structure. The feed pipe can be installed according to the on-site conditions and can be installed on the ground or buried under the ground. For example, when passing through a road, the feed pipe can be buried under the ground. The number of connecting pipes is arranged into multi-point interfaces according to the number of warehouses for storing dead branches and fallen leaves and the planned warehouses. If there are two warehouses for storing dead branches and fallen leaves, the first end of the feed pipe is set in one of the warehouses, and then a connecting pipe is set in the other warehouse. When material transportation is not in progress, the first end of the feed pipe and the end of the connecting pipe are both installed with flange covers that are flush with or close to the ground to seal the feed pipe.

The crushed dead branches and leaves are loose, low in density, and relatively dry. The fan can suck the crushed dead branches and leaves into the barrel. After the air is filtered through the filter, it is drawn out by the fan. The dead branches and leaves accumulate in the barrel. After the barrel is full, open the discharge gate and the dead branches and leaves fall into the mixer hopper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0017] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 The positional relationships of front, back, top, bottom, left, and right are described in the layout of the manual. Figure 1 The layout direction is determined by the

[0018] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0019] Example 1: As shown in the attached Figure 1 As shown, the pneumatic conveying device for dead branches and leaves includes a fan 1, a feed pipe 2, a connecting pipe 3, a hose 4 and a barrel body 6 with a barrel cover 5 sealed on the upper end. The lower end of the barrel body 6 is provided with an internally and externally connected discharge port and a discharge gate 7 capable of opening and closing the discharge port. The upper outer side of the barrel body 6 is provided with internally and externally connected air outlet holes and air inlet holes at intervals above and below. A filter screen 8 is installed on the inner side of the upper part of the barrel body 6 at a position corresponding to the air inlet hole and the air outlet hole. The air outlet hole is fixedly connected to the air inlet of the fan 1, and the air inlet hole is fixedly connected to the first end of the feed pipe 2. Several connecting pipes 3 are fixedly connected at intervals along the length direction on the feed pipe 2, and the second end of the feed pipe 2 or / and the end of at least one connecting pipe 3 are detachably installed with a hose 4.

[0020] According to the needs, the fan 1 is an existing well-known exhaust fan, and the filter 8 is an existing well-known technology, such as a dust removal filter cloth. In order to ensure the utilization space of the barrel body 6, the upper side of the filter 8 is flush with the lower side of the air outlet. The feed pipe 2 can be installed according to the on-site conditions. It can be installed on the ground or buried under the ground. For example, when passing through a road, the feed pipe 2 is buried under the ground. The number of connecting pipes 3 is arranged into multi-point interfaces according to the number of warehouses 15 for storing dead branches and fallen leaves and the number of planned warehouses 15. If there are two warehouses 15 for storing dead branches and fallen leaves, the first end of the feed pipe 2 is set in one of the warehouses 15, and then a connecting pipe 3 is set in the other warehouse 15. When material transportation is not in progress, the first end of the feed pipe 2 and the end of the connecting pipe 3 are both equipped with a flange cover 16 that is flush with or close to the ground to seal the feed pipe 2.

[0021] When taking dead branches and leaves from one of the warehouses 15, the nearest flange cover 16 in the warehouse 15 is removed and the hose 4 is installed. The hose 4 can be of existing well-known technology, such as a ribbed hose or a steel wire hose. After starting the fan 1, the other end of the hose 4 is close to the crushed dead branches and leaves. The crushed dead branches and leaves are loose, low in density, and relatively dry. The fan 1 can suck the crushed dead branches and leaves into the barrel body 6. After the air is filtered by the filter 8, it is extracted by the fan 1. The dead branches and leaves accumulate in the barrel body 6. After the barrel body 6 is full, the discharge gate 7 is opened and the dead branches and leaves fall into the mixer hopper 18.

[0022] The above-mentioned pneumatic conveying device for fallen branches and leaves can be further optimized and / or improved according to actual needs:

[0023] Example 2: As an optimization of the above example, as shown in the attached Figure 1 As shown, the cart is also included, which includes a bucket 9 and wheels 10. There is a feed port on the right side of the bucket 9, an axle 11 is installed on the left side of the lower part of the bucket 9, and wheels 10 are rotatably installed at both ends of the axle 11. The right part of the hose 4 is fixedly installed on the inner side of the left part of the bucket 9, and a handle 12 is fixedly installed on the upper side of the left part of the bucket 9.

[0024] During use, the bucket 9 is pushed forward, and the piled crushed dead branches and leaves are shoveled into the bucket 9. The fan 1 is started, and the dead branches and leaves in the bucket 9 are sucked into the barrel 6 through the feed port, the hose 4 and the feed pipe 2. The air is filtered by the filter 8 and then drawn out by the fan 1. The dead branches and leaves accumulate in the barrel 6. After the barrel 6 is full, the discharge gate 7 is opened, and the dead branches and leaves fall into the mixer hopper 18. The fan 1 is started, and the fan 1 has a suction effect on the feed pipe 2 and the hose 4, so that the dead branches and leaves in the bucket 9 are sucked into the barrel 6 through the feed port, the hose 4 and the feed pipe 2. The dead branches and leaves will be blocked by the filter 8, and the air is filtered by the filter 8 and then drawn out by the fan 1. The fan 1 continues to work to accumulate the dead branches and leaves in the barrel 6. After the barrel 6 is full, the discharge gate 7 is opened, and the dead branches and leaves fall into the mixer hopper 18.

[0025] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, the end of the hose 4 has an inclined guide surface 13, and the distance between the guide surface 13 and the inner side of the lower part of the bucket 9 gradually increases from left to right.

[0026] During use, push the handle 12 to move the bucket 9 and shovel in the material. After the bucket 9 shovels in the material, press down the handle 12 to lift the right end of the bucket 9, which is more conducive to material suction. The guide surface 13 can increase the feeding area of the end of the hose 4 and increase the feeding rate.

[0027] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, an air extraction pipe 14 is fixedly connected between the air outlet and the air inlet of the fan 1.

[0028] During use, by setting up the exhaust pipe 14, the exhaust pipe 14 can be installed according to the installation position and installation height of the barrel body 6, reducing the difficulty of installation between the fan 1. For example, the mixer hopper 18 is installed in the pit 17, and the barrel body 6 is installed above the mixer hopper 18. In this way, the exhaust pipe 14 can make the installation and maintenance between the fan 1 and the barrel body 6 more convenient.

[0029] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1As shown, the lower portion of the barrel body 6 corresponding to the position below the air inlet gradually becomes thinner from top to bottom.

[0030] The lower part of the barrel body 6 below the air inlet gradually tapers from top to bottom, that is, the inner wall of the lower part of the barrel body 6 is a cone or a prism or a funnel shape with a larger top and a smaller bottom. During use, this is more conducive to the material falling into the mixer hopper 18.

[0031] The above technical features respectively constitute the various embodiments of the present invention, which have strong adaptability and optimal implementation effects. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
