Description

Technical Field

[0001] The invention belongs to the field of artificial silkworm feed production equipment, and in particular relates to a material-water ratio stirring system. Background Art

[0002] The traditional breeding method is a small-scale family-based breeding method, which is a fully artificial breeding method. All processes from silkworm eggs to adulthood to cocoon collection are done through manual operation. It is time-consuming and labor-intensive, with very low breeding efficiency. In addition, silkworms can only be raised at specific times due to seasonal conditions. The annual output of silkworm cocoons is extremely low, which cannot meet the needs of today's society and has been gradually eliminated by society.

[0003] In order to make up for the shortcomings of traditional workshop-style silkworm farming, large-scale and factory-based silkworm farming technology was applied. In large-scale breeding technology, if mulberry leaves are used as feed, it is completely unable to meet the requirements of factory-based silkworm farming. Therefore, artificial feed plays an important role in factory-based and large-scale silkworm farming technology. The production process of artificial feed is mainly divided into three steps: raw material processing, cooking and feed cooling. Raw material processing is to evenly mix corn, soybean meal, complex vitamins, etc. and remove impurities to obtain powder. Cooking is to first add water to the powder to obtain raw feed, and then cook the raw feed into cooked feed. The cooked feed becomes finished feed after cooling.

[0004] It can be seen that cooking is an important step in the feed production process. Before cooking, the powder needs to be mixed with water to make raw materials, and then the raw materials are sent to the cooking. In the prior art, the preparation of raw materials requires manpower, including manual weighing and quantitative, manual feeding, and manual transportation of raw materials to the cooking equipment, which is very inconvenient, time-consuming and labor-intensive, and seriously affects the efficiency of cooking and batching.

The dry powder entering the dry powder tank is filtered and impurities are removed by a screening mechanism to reduce the impurity content in the raw material finally formed by mixing. After removing the impurities, the dry powder composition is also made more uniform, so that it is easier to form a homogeneous raw material when mixed with water, which helps to improve the quality of the final feed.

DETAILED DESCRIPTION

[0035] The present invention aims to provide a material-water ratio mixing system, which is equipped with a water tank 3 and a raw material tank 15 for a mixer 1. Water and dry powder can be quantitatively added to the mixer 1 through the water tank 3 and the raw material tank 15, so as to achieve the purpose of automatic and continuous raw material preparation, without the need for manual weighing, feeding, and transportation, etc., and significantly improve the efficiency of steaming and mixing ingredients. The dry powder entering the dry powder tank 13 is filtered and impurity-removed by a screening mechanism 23, so as to reduce the impurity content in the raw material finally formed by stirring. After removing the impurities, the dry powder composition is also made more uniform, so that it is easier to form a homogeneous raw material when mixed with water, which helps to improve the quality of the final feed. In addition, removing impurities can also avoid the wear of the impurities on the equipment in the system and the blockage of the pipeline.

[0036] like Figures 1 to 14As shown, a material-water ratio mixing system of the present invention includes a mixer 1, a water tank 3, a dry powder tank 13 and a metering pump 16. The water tank 3 is used to supply water to the mixer 1, and the dry powder tank 13 is used to supply powder to the mixer 1. The mixer 1 is used to mix water and dry powder to generate raw materials, so as to achieve the purpose of automatic and continuous preparation of raw materials, without the need for manual weighing, feeding, and transportation, etc., and significantly improve the efficiency of steaming and batching. The obtained raw materials are fed to the steaming line through the metering pump 16, and cooked feed is obtained after steaming.

A screening mechanism 23 is provided at the feed inlet section 59 of the dry powder tank 13, and the dry powder conveyed to the dry powder tank 13 is filtered and screened by the screening mechanism 23.

[0037] The water tank 3 is connected with a clean water pipe 7, a recycled water pipe 5 and a downpipe 10. The downpipe 10 is connected to the mixer 1. The clean water pipe 7 is connected to an external water supply device and is used to add clean water to the water tank 3. As the main water pipe, the clean water pipe 7 is provided with a first pneumatic valve 8, which can control the opening or closing of the clean water pipe 7, and can also control the size of the opening. The recycled water pipe 5 recycles the excess water retained in the mixer 1 into the water tank 3, realizes the recycling of water materials, and recycles the dry powder in the recycled water, which conforms to the production concept of energy saving and environmental protection. The recycled water pipe 5 is provided with a second pneumatic valve 6, which can control the opening or closing of the recycled water pipe 5, and can also control the size of the opening.

[0040] The mixing system also includes a raw material bin 15. The mixer 1 fully mixes the dry powder and water through mixing to finally obtain raw material. A mixer discharge port 2 is provided on the side thereof. The prepared raw material is discharged into the raw material bin 15 through the mixer discharge port 2 for storage. The raw material bin 15 plays a transitional role. When the preparation speed is faster than the cooking speed, the excess raw material can be stored for backup. When the cooking speed is faster than the preparation speed, the pre-stored raw material can be supplied to the cooking line to avoid the problems of insufficient raw material process and excessive raw material supply, reduce failures and improve efficiency.

[0041] The feed port of the raw material bin 15 is connected to a feed pipe 17, and the other end of the feed pipe 17 is connected to the cooking line.

The metering pump 16 includes a motor 21 and a pump body 22. The inlet and outlet of the pump body 22 are respectively connected to the feed pipe 17. The metering pump 16 provides power for the raw material to be transported to the cooking line in a directional manner, realizing automatic feeding without manual handling, and further improving the efficiency of cooking and batching. The feed pipe 17 is provided with a valve 19 and a sight glass 20 near the raw material bin 15. The valve 19 can be used to control whether the raw material bin 15 is fed, and the sight glass 20 is convenient for observing the feeding condition in the feed pipe.

[0042] like Figure 6 As shown, the feeding pipe 17 is located at the end of the cooking line and is connected to a forming head 18. According to production needs, the forming hole of the forming head 18 can be of different shapes, such as a flat rectangular forming hole (such as Figure 6 C), circular forming holes set at equal intervals (such as Figure 6 A) or square forming holes arranged at equal intervals (such as Figure 6 B), etc., can deliver flat feed, round strip feed or square strip feed, etc., to meet different cooking requirements.
