Description

Description
The present invention relates to device for monitoring the load of material in a container. The present invention further relates to a method for monitoring the load of material present in a container using a device of present invention.
The monitoring of the content levels of a silo or bioreactor in for example the livestock feed of food sector (storage of animal feed, foods and raw materials), chemical industry (storage of powder, plastic granules) remains a challenge. For example an agricultural company orders bulk material from a supplier and stores the material in silos for use in the production of new products or in feeding of animals. However, the company will notice only at a late stage that it is running low on or even out of material and subsequently a swift delivery of new bulk material is necessary. The urgent delivery is done via third party suppliers, which need to be able to deliver quickly and should have enough of the requested material in stock. This all complicates the logistics for the supplier and may lead to extra costs.
To monitor or measure the content level or load in containers, such as silos or bioreactors sensor can be used, so that the farmer or producer is better informed about the level of bulk material in the silo, reducing the problem. However, sensor application of the prior art measuring the load inside a reactor are often positioned inside the reactor or silo and have the problem that they do not work properly and are unreliable. The problem is that during loading and unloading of the silo, a lot of dust (in case of small particulate solids) or condensation (liquids) is created in the silo which will influence the sensor detection, because the sensor will get dirty which negatively affects the sensor. Another problem is that there is a high risk of explosion when using electronics in a dusty environment.
Furthermore, the material that is being determined inside the silo or container influences the difficulty to measure/determine the load of the reactor. For instance, whether the surface of the material is uniform or irregular, heavy or light, solid or liquid, etc. Especially the monitoring of the level or load of solids inside a reactor remains a challenge, such as granular materials, powders or pellets, because such materials tend to shift, settle irregularly and/or compress in the reactor. For example, a solid material that is stored in the container does not necessarily have an even top level (surface) due to bridge formation, unlike liquids. This often leads to measurement inaccuracy.
In order to monitor the content inside the silo sophisticated sensor applications and expensive tools, such as radar based sensor technology or ultrasonic systems are needed that are integrated with mathematical models to compensate for the material behaviour. Determining the content level in a container a 3D device or radar-based sensor can be used. However, such non contact devices give unreliably measurements in dusty conditions and their installation is often expensive due to the sophisticated sensors and very complex.
Considering the above, there is a need in the art for a simple and inexpensive device for improved monitoring of the level of a bulk material in a container. In addition there is a need in the art for a method for monitoring the load of a container, for example in food production companies, in order to optimise (stock) load predictions, logistics and factory planning in relation to storage and purchase of raw materials.
It is an object of the present invention, amongst other objects, to address the above need in the art. The object of present invention, amongst other objects, is met by the present invention as outlined in the appended clauses.
Specifically, the above object, amongst other objects, is met, according to a first aspect, by the present invention by a device (4) for monitoring the load of material (2) in a container (1), wherein the device (4) is comprised of a housing (5) holding a weight sensor (7), at least one body (3) attached to the w'eight sensor (7) for measuring a pulling force exerted on said at least one body (3) by the material (2) in the container (1), wherein the at least one body (3) is located inside the container (1), said at least one body (3) extending from the top of the container (I) downward in the container in a vertical direction, substantially parallel to a vertical side wall (II) of the container, wherein the at least one body (3) extends over at least 50% of the length of the vertical side wall (11) of the container (1).
A container filled with (bulk) material will exert a pulling force on the at least one body which is measured by a weight sensor. The body, for example a steel cable, is located in the container and when the material level increases, it generates a traction/friction on this body because the material “rubs” against the body, generating a pulling force. The higher the feed level, the higher the pulling force on the body. This pulling force is measured by the weight sensor on the top of the container.
The housing and sensor can be connected to a pow'er source and communication means to be able to generate and transfer the sensor data to a receiving means, such as a back-end system and/or receiver device to analyze or visualize the sensor data. Sensor data of the weight sensor can be transmitted to a receiver device in order to collect the data on the load of the container.
The pulling force exerted on the body depends on the type of material inside the container, e.g. solids versus liquids or solids of large particle size versus powdered solids. Depending on the material and the pulling force, a load inside the container is calculated and can be real time monitored. The device is primary intended for use in a animal feed silo to measure bulk solids, but can also be used for other industry storing solids in silo’s, such as plastic pellets, flour, salt, etc., and as well liquids with a low' to high viscosity.
A solid material that is stored in the container not having an even top level due to bridge formation can be monitored using the device of present invention, because the load level of the container is measured and determined indirectly via the pull force exerted on the body. The device according to the present invention can be used for both liquids and solids and is not affected by irregular levels of solids or liquids in the container. The solid bulk material is for example a powder.
As a weight sensor, such as a loadcell can be placed in a housing, which can be placed on the outside on top of the container. Because the sensor is located in an enclosed environment, possible dusty and moisture problems that may negatively influence the sensor measurements are avoided, because the sensor is separated from the inside of the container holding the (bulk) material, such as granules or liquids. Furthermore, there is not risk of explosions due to the electrical parts of the sensor when coming in to contact with specific dust concentrations in case of granulated material inside the container. Finally, the device of present invention is very simple and inexpensive to produce and to operate, since the device of present invention comprising a simple weight sensor, such as a load cell, attached to a body that is located inside the reactor.
According to a preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) is extending downward from a substantially central location from the top of the container (I). Materials have a tendency to adhere/stick to the side wall (11) of the container. Because the side wall (11) of a container affect (slightly reducing) the pull force of the material exerted on the body, it is preferred that the body is located in a central position in the reactor. This way the affects of the side wall of the container are minimized.
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) is attached to the weight sensor (7) via force absorption means (8, 8’), wherein said force adsorption means is an elastic element, such as a spring element (8) or a rubber element (8’). The force adsorption means function as a shock absorber that serves as a dampener of the pulling force, thereby protecting the weight sensor against peak pull force, for example exerted on the body and weight sensor during loading of the container with material.
According to yet another preferred embodiment, the present invention relates to the device (4), wherein the weight sensor (7) is further connected to the at least one body (3) via a lever (9). The lever (9) functions as a force decrease tool. The lever will decrease the force which is generated onto the weight sensor (7) (e.g. a load cell sensor). This means that a smaller and more cost effective weight sensor can be used, when the device of present invention includes the lever (9).
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) comprises one or more steps (12), wherein said steps are horizontally positioned on said at least one body (3). These steps increase the contact surface of the body with the materials inside the container, thereby leading to an increase in pulling force on the body. The steps improves the sensitivity of the measurement because the body becomes, depending on the number of steps present on the body, more sensitive to changes in pulling force on said body.
According to a preferred embodiment, the present invention relates to the device (4), wherein said one or more steps (12) is at least two steps and wherein the distance between each step is at most 50 cm, more preferably at most 25 cm, most preferably at most 10 cm.
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body further (3) comprises an object (14) located at its lower end, wherein said object (14) is a ball shaped object, a cone shaped object, a cube-shaped object. For instance a metal ball on the end of the cable results in an increase in the pulling force exerted on the body (3). For materials, such as powdered solids, it may be preferred to have such an object present at the far end of the body to further increase the sensitivity of monitoring materials that have low density or weight, such as powdered materials or liquids having low viscosity.
According to yet another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) comprises a smooth finish at its lower end, preferably wherein said smooth finish is a tubing, preferably a heat shrink tubing. Due to constant movement of material going in and moving out of the container, resulting in friction and resistance on the at least one body (3) present in the container, which in time may affect the integrity and durability of this body. Especially the low end of the at least one body of present invention is prone to such durability problems. In order to protect this low end of the at least one body a smooth finish is preferred, such as to provide the low end of the body with a tubing.
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) is made of non-elastic material having a stiffness of at least 50 N/m2, preferably at least 100 N/m2, more preferably at least 120 N/m2.
According to a preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) is made of material comprised of metal, preferably steel or aluminium, or non-elastic polymer such as Dyneema.
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) has a thickness of at least 1 mm to 10 cm, preferably 2 mm to 5 cm, most preferably 5 mm to 10 mm. The thickness of the body influences pulling force by increasing the contact surface of the body with the material in the container.
According to yet another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) extends over at least 75% of the internal height of the container (1), preferably at least 85%, more preferably at least 90%. Most containers, such as food silos have a funnel shaped bottom to provide an optimal output of the material from the silo. In order to reduce the influence of the side wall/funnel shape on the pull force on the body, it is preferred that the body runs in length from the top to 90% in the silo, so that it does not enter the funnel.
According to a preferred embodiment, the present invention relates to the device (4), wherein said at least one body (3) are multiple bodies, wherein said multiple bodies differ independently from each other in their degree of extending downward in the container (1). The various degree of extension of multiple bodies inside the container provides that each body can measure various loads inside a container. The “shortest” body, for example extending only 10% in length from the top in to the container, may only be able to measure a fully loaded container.
According to another preferred embodiment, the present invention relates to the device (4), wherein the at least one body (3) is a string, a cable, a rod, or a cord.
