DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a sludge dehydration and dosing stirring device, including a stirrer 1, a stirring shaft 2 is rotatably installed in the stirrer 1, a stirring rod 203 is fixedly connected to the stirring shaft 2, a support seat 3 is fixedly connected to one side of the stirrer 1, a medicine storage box 301 is fixedly connected to the front of the support seat 3, a delivery pipe 4 is fixedly connected to the upper end of the support seat 3, an auger 403 is rotatably installed in the delivery pipe 4, a pumping ring pipe 5 is sleeved on the delivery pipe 4, a nozzle 501 is fixedly connected to the inner wall of the pumping ring pipe 5, a through hole 404 is opened on the outer wall of the delivery pipe 4, and the nozzle 501 is fixedly installed in the through hole 404.

[0023] In the present embodiment, the delivery pipe 4 cooperates with the auger 403 to form an auger delivery pipe, and the sludge is added into the auger delivery pipe, and the sludge is delivered to the agitator 1 through the auger delivery pipe. The nozzle 501 is connected to the inside of the delivery pipe 4 through the through hole 404, so that the agent can be pumped into the delivery pipe 4 through the nozzle 501, and the agent is evenly added to the sludge when the sludge is transported. The sludge is stirred by the stirring rod 203 to further fully mix the sludge and the agent together. Since the agent is evenly added to the sludge in advance, it is convenient to fully mix the agent and the sludge in the later stirring, thereby effectively increasing the stirring and mixing efficiency.

[0024] Among them, in order to achieve the purpose of discharging, the present device is implemented by the following technical scheme: a support leg 101 is fixedly connected to the bottom of the agitator 1, a discharge port 102 is opened at the bottom of the agitator 1, a baffle 103 is rotatably installed below the agitator 1 and below the discharge port 102, a handle 104 is fixedly connected to the bottom of the baffle 103, and a limiting protrusion 105 is fixedly connected to the bottom of the agitator 1 and behind the discharge port 102.

[0025] The agitator 1 is supported at a suitable height by the support legs 101, so that the transfer equipment can be placed under the agitator 1. The baffle 103 can block the discharge port 102. The handle 104 can drive the baffle 103 to rotate, thereby moving the baffle 103 away from under the discharge port 102. At this time, the sludge can be discharged through the discharge port 102. The limiting protrusion 105 can interfere with the baffle 103. After the baffle 103 rotates to below the discharge port 102, it can prevent the baffle 103 from continuing to rotate, thereby quickly resetting the baffle 103.

[0026] Among them, in order to achieve the purpose of uniformly spraying the mixed medicine, the present device is implemented by the following technical scheme: a stirring motor 201 is fixedly connected to the bottom of the agitator 1, the output end of the stirring motor 201 is fixedly connected to the stirring shaft 2, an arc-shaped scraper 202 is fixedly connected to the stirring shaft 2, the bottom of the arc-shaped scraper 202 fits the bottom of the agitator 1, a power motor 402 is fixedly connected to one side of the conveying pipe 4, the output end of the power motor 402 is fixedly connected to the auger 403, a feed hopper 401 is fixedly connected to the top of the conveying pipe 4, a connecting hose 502 is fixedly connected to the pumping ring pipe 5, a pump is arranged in the medicine storage box 301, and the output end of the pump is fixedly connected to the other end of the connecting hose 502.

[0027] By starting the stirring motor 201, the stirring shaft 2 can be driven to rotate. The rotation of the stirring shaft 2 will synchronously drive the stirring rod 203 and the arc scraper 202 to rotate. The rotation of the stirring rod 203 will stir the sludge inside the stirrer 1. The rotation of the arc scraper 202 will scrape the sludge at the lower end to the edge, so as to facilitate the sludge to be scraped into the discharge port 102 for discharge. The sludge can be fed into the conveying pipe 4 through the feed hopper 401. Starting the power motor 402 can drive the auger 403 to rotate, thereby continuously conveying the sludge into the stirrer 1. Starting the pump in the agent storage box 301 can pump the agent to the pumping ring pipe 5 through the connecting hose 502, and then spray it into the sludge through the nozzle 501.

[0028] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the sludge is fed into the feed hopper 401, the power motor 402 is started to drive the auger 403 to rotate, and the rotation of the auger 403 will drive the sludge to be transported to the inside of the agitator 1, and the pump in the agent storage box 301 is started, and the agent can be pumped to the pumping ring pipe 5 through the connecting hose 502, and the agent is sprayed into the delivery pipe 4 through the nozzle 501, so that the agent is evenly mixed into the sludge when the sludge is transported, and then the stirring motor 201 is started to drive the stirring rod 203 to rotate, stir the sludge transported to the agitator 1, and further fully mix the sludge and the agent together, and then the baffle 103 is driven by the handle 104 to rotate to open the discharge port 102, and the sludge will be discharged from the inside of the agitator 1.
