Description

Technical Field

[0001] This utility model relates to the field of aluminum phosphide chemical fumigation, and in particular to an aluminum phosphide residue treatment device. Background Technology

[0002] Phosphine fumigation is one of the main methods of pest control during grain storage. The usual method is to use aluminum phosphide to generate phosphine gas through natural deliquescence, and then use the phosphine gas to kill pests.

[0003] The problem with the existing technology is that 3%-5% of aluminum phosphide remains in the reagent residue formed after the natural deliquescence of aluminum phosphide and cannot be completely decomposed. According to regulations, the reagent residue needs to be put into boiling water for stirring treatment. When the reagent residue is stirred with hot water, it can react quickly and release phosphine gas. After the treatment is completed, the reagent residue must be completely discharged.

[0004] The problem with the existing technology is that the degree of human intervention in the entire process of treating the reagent residue is too high. Since phosphine gas is toxic, the high degree of human intervention can easily lead to poisoning accidents. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum phosphide residue treatment device to solve the technical problem that the high degree of human intervention in the treatment of aluminum phosphide residue in the prior art makes it easy for poisoning accidents to occur.

[0006] The technical solution of this utility model is as follows: A treatment device for aluminum phosphide residue includes a treatment chamber, a mixing tank and a water storage tank equipped with a heating device are installed inside the treatment chamber. A water supply pipeline is installed between the bottom of the water storage tank and the top of the mixing tank, and a water pump is installed on the water supply pipeline. The mixing tank includes a tank body and a mixing device. A feeding port is installed at the top of the tank body, and a feeding door that can be opened or closed is installed at the feeding port. A phosphine concentration sensor is installed at the feeding port. An air outlet is installed at the upper end of the tank body, and a slag discharge port is installed at the bottom of the tank body. A slag discharge solenoid valve is installed at the slag discharge port, and a slag discharge pipe extending to the outside of the treatment chamber is connected to the slag discharge port. The air outlet and the slag discharge pipe are connected by an exhaust pipe.

[0007] Furthermore, an exhaust fan is connected in series with the exhaust pipe.

[0008] Furthermore, an exhaust pipe solenoid valve is installed upstream of the slag discharge port on the exhaust pipe.

[0009] Furthermore, the stirring device includes a stirring motor, on which a stirring shaft is provided that extends into the tank body, and stirring blades are provided on the stirring shaft.

[0010] Furthermore, a feeding funnel is provided at the feeding port, which is located on one side of the stirring motor. A feeding gate is provided at the upper end of the feeding funnel, and an installation groove is provided on the inner wall of the feeding funnel. The phosphine concentration sensor is installed in the installation groove.

[0011] The beneficial effects of this technical solution are as follows: During use, the slag discharge solenoid valve is closed, and the operator adds the aluminum phosphide residue to the mixing tank through the feeding port. Then, the feeding door is closed, and the operator leaves the treatment chamber. A water pump delivers hot water from the storage tank to the mixing tank, where the mixing device stirs the residue. The aluminum phosphide residue reacts with the hot water to quickly generate phosphine gas. This phosphine gas is discharged from the treatment chamber through the exhaust pipe and slag discharge pipe, preventing phosphine gas accumulation. A phosphine concentration sensor continuously monitors the phosphine gas concentration in the mixing tank. When the concentration falls below a certain threshold, the slag discharge solenoid valve is opened, and the aluminum phosphide residue is discharged from the treatment chamber with the water through the slag discharge pipe. The operator can then enter the treatment chamber to process new aluminum phosphide residue. Throughout the process, the operator only needs to add the untreated aluminum phosphide residue to the mixing tank and does not participate in the residue processing, reducing the probability of inhaling toxic gases.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0016] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0017] A specific embodiment of an aluminum phosphide residue treatment device of this utility model is as follows: Figures 1-2 As shown, The system includes a processing chamber 14, on which louvers 1 are provided for ventilation. In this embodiment, the processing chamber is a prefabricated structure that is easy to move. The processing chamber has an entrance and a door that can be opened or closed.

[0018] The processing room is equipped with a device base 2, on which a mixing tank and a water storage tank 15 with a heating device are installed. That is to say, the mixing tank and the water storage tank are installed on the device base for easy transportation to the site. In this embodiment, the heating device is a heating coil, which can heat the water in the water storage tank. The water storage tank with the heating device is existing technology and will not be described in detail here.

[0019] A water supply pipe 13 is provided between the bottom of the water storage tank and the top of the mixing tank. A water pump 16 is installed on the water supply pipe. The mixing tank includes a tank body 5 and a mixing device. The mixing device includes a mixing motor 10. A mixing shaft 6 extending into the tank body is provided on the motor shaft of the mixing motor 10. Mixing blades 4 are provided on the mixing shaft 6. The mixing device is prior art, and its structure will not be described in detail here.

[0020] A feeding port is provided at the top of the tank, and a feeding door plate 8 that can be opened or closed is provided at the feeding port. In this embodiment, a feeding funnel 7 is provided at the feeding port, and the feeding funnel 7 is located on one side of the stirring motor 10. The feeding door plate 8 is located at the upper end of the feeding funnel 7, and the right side of the feeding door plate is hinged to the upper end of the feeding funnel. That is to say, in this embodiment, the left end of the feeding door plate is flipped to open or close the feeding port at the upper end of the feeding funnel. An installation groove 1 is provided on the inner wall of the right side of the feeding funnel. The phosphine concentration sensor 9 is installed in the installation groove 1. The aluminum phosphide concentration sensor is not installed in the tank but on the inner wall of the feeding funnel. In this way, the phosphine concentration sensor can successfully detect the phosphine concentration in the tank, and no liquid will splash onto the phosphine concentration sensor when the stirring device is working, thus ensuring the service life of the phosphine concentration sensor. The left side wall of the feeding funnel is a sloping plate structure that gradually extends to the right from top to bottom.

[0021] The tank has an air outlet at the top and a slag discharge port at the bottom. A slag discharge solenoid valve 19 is installed at the slag discharge port, and a slag discharge pipe 3 extending to the outside of the treatment room is connected to the slag discharge port. The air outlet and the slag discharge pipe are connected by an exhaust pipe 17. An exhaust fan 12 is connected in series on the exhaust pipe 17, and an exhaust pipe solenoid valve 18 is installed on the exhaust pipe 17 upstream of the slag discharge port.

[0022] In other words, in this embodiment, the slag discharge pipe can discharge both aluminum phosphide residue and phosphine gas. It is used for the common discharge of slag and gas, thus reducing the complexity of the equipment structure.

[0023] In other embodiments of this utility model, the exhaust fan 12 may be omitted. In this case, the phosphine gas generated by the hydrolysis of aluminum phosphide residue can be naturally discharged through the exhaust pipe 17 and the slag discharge pipe 3 by natural volatilization.

[0024] During operation, the slag discharge solenoid valve is closed. The operator adds the aluminum phosphide residue to the mixing tank through the feeding port, then closes the feeding door and leaves the treatment chamber. The water pump delivers hot water from the storage tank to the mixing tank, where the mixing device stirs the residue. The aluminum phosphide residue reacts with the hot water to quickly generate phosphine gas. This gas is discharged from the treatment chamber through the exhaust pipe and slag discharge pipe, preventing phosphine gas accumulation. A phosphine concentration sensor continuously monitors the phosphine gas concentration in the mixing tank. When the concentration falls below a certain threshold, the slag discharge solenoid valve is opened, and the aluminum phosphide residue is discharged from the treatment chamber with the water through the slag discharge pipe. The operator can then enter the treatment chamber to process new aluminum phosphide residue. Throughout the process, the operator only needs to add the untreated aluminum phosphide residue to the mixing tank and does not participate in the residue processing, reducing the probability of inhaling toxic gases and ensuring operator safety during aluminum phosphide residue treatment.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
