[0047] Plate and frame filter press is a device for separating solid and liquid in industrial production, which can be applied to chemical industry, ceramics, petroleum, medicine, food, smelting and other industries, and plays a great role in sewage treatment.

[0048] A large amount of sludge is generated in a municipal sewage treatment plant every day, in order to reduce the volume of sludge for final disposal, sludge dewatering is an important treatment link, the sludge needs to be discharged into a sludge pool, a coagulant drug is put in, an alum flower generation phenomenon is generated, a sedimentation effect is achieved, the sludge weight in the next sludge dewatering process is reduced, and the efficiency of sludge dewatering equipment and personnel is improved.

[0049] However, at present, the pool capacity of the sludge pool in the water treatment plate and frame workshop is small, the amount of sludge discharged into the sludge pool is large, and the sludge pool is always in a full pool state, so that the coagulant drug put in is difficult to fully react with the sludge. The existing technology is to improve the degree of reaction of the two by stirring, such as adding a stirring mechanism, which needs to reform the whole sludge pool, and the energy consumption is large.

[0050] In order to provide a sludge pool drug mixer for water treatment plate and frame workshop, which is used for mixing the drug with the sludge in advance when the sludge enters the sludge pool, ensuring that the drug and the sludge fully react, and reducing the waste of the drug.

[0051] Please refer to Figure 1In a specific embodiment, the sludge tank chemical mixer in the water treatment plate and frame workshop includes a mixing chamber 1, a sludge input pipe 2, and a sludge output pipe 3.

[0052] The mixing chamber 1 is provided with a sludge inlet 10, a sludge outlet 11, and a dosing port 12. The sludge inlet 10 is the opening for inputting sludge into the mixing chamber 1, the sludge outlet 11 is the opening for outputting sludge from the mixing chamber 1, and the dosing port 12 is the opening for adding coagulant into the mixing chamber 1.

[0053] The sludge inlet 10 and the dosing port 12 are both located at the bottom of the mixing chamber 1, and the sludge outlet 11 is located at the top of the mixing chamber 1. That is, the height of the sludge inlet 10 and the height of the dosing port 12 are both lower than the height of the sludge outlet 11. The sludge is transported from the sludge inlet 10 to the sludge outlet 11, that is, the sludge is transported upwards. The sludge is initially mixed with the coagulant drug added to the mixing chamber 1 when it enters the mixing chamber 1.

[0054] Please see Figure 2 , Figure 3 The mixing chamber 1 is equipped with an upwardly curved mixing channel 13 that connects the sludge inlet 10 and the sludge outlet 11. The sludge needs to change direction and speed frequently during its movement within the mixing channel 13. The dosing port 12 is connected to the mixing channel 13, meaning that the coagulant added through the dosing port 12 can enter the mixing channel 13.

[0055] One end of the sludge input pipe 2 is connected to the sludge inlet 10 of the mixing chamber 1; both ends of the sludge output pipe 3 are connected to the sludge outlet 11 of the mixing chamber 1 and the sludge tank, respectively. That is, the sludge input pipe 2 is connected to the mixing chamber 1 and the sludge output pipe 3, and the sludge needs to pass through the mixing chamber 1 before it can be discharged into the sludge tank.

[0056] The aforementioned chemical mixer for the sludge tank in the water treatment plate and frame workshop features a mixing chamber 1 for adding coagulant chemicals, located between the sludge input pipe 2 and the sludge output pipe 3. Before entering the sludge tank, the sludge must first pass through the mixing chamber 1 into the mixing channel 13. The sludge inlet 10 of the mixing chamber 1 is located below the sludge outlet 11, and the mixing channel 13 is a winding path. Therefore, the sludge needs to move from bottom to top within the mixing channel 13, frequently changing its direction of movement to alter its direction and slow its speed. This achieves the purpose of self-stirring of the sludge within the mixing chamber 1. Pre-adding coagulant chemicals inside facilitates rapid mixing, ensuring sufficient reaction between the coagulant chemicals and the moving sludge. This pre-mixing of the coagulant chemicals before the sludge enters the sludge tank solves the problem of insufficient chemical reaction, significantly improves efficacy, and reduces chemical consumption. Furthermore, this structure is simple and practical, can be made using recycled materials, and is inexpensive.

[0057] The structure of the mixing channel 13 can be various, please refer to Figure 2 As example one: the mixing channel 13 is divided by two rows of vertically arranged baffles 14, the two rows of baffles 14 are respectively arranged at the two sides of the mixing chamber 1, and are staggered with each other, so that the internal space of the mixing chamber 1 forms a zigzag winding channel.

[0058] The number of baffles 14 in each row can be set according to the actual height of the mixing chamber 1, for example, one row of baffles 14 is provided with two baffles 14, and the other row of baffles 14 is provided with one baffle 14, and the baffle 14 is arranged between the two baffles 14, and three baffles 14 divide the internal space of the mixing chamber 1 into a bending channel. In addition, the baffle 14 can be arranged horizontally.

[0059] The baffle 14 changes the direction of the sludge movement, in order to better mix the sludge with the drug, please refer to Figure 3 In example two, the baffle 14 is arranged downwardly inclined, which can further reduce the upward movement speed of the sludge, thereby increasing the mixing time of the sludge and the drug, and further improving the reaction degree of the sludge and the drug.

[0060] The inclination angle of the baffle 14 can be 30° to 60°, such as 45°, and the shorter end of the baffle 14 is located above the next baffle 14.

[0061] Please refer to Figure 4 In some embodiments, the baffle 14 is provided with stirring protrusions 140, by arranging the stirring protrusions 140, the movement of the sludge on the baffle 14 has more ups and downs, and the self-stirring effect of the sludge is improved to a greater extent. The stirring protrusions 140 can be a plurality of sharp stirring protrusions, a plurality of sharp protrusions are uniformly and staggered distributed on the baffle 14, or the stirring protrusions are in strip shape, and the length is consistent with the length of the baffle 14, and a plurality of stirring protrusions are equidistantly arranged along the length direction of the baffle 14.

[0062] Please refer to Figure 5 In example three, the mixing channel 13 can also be in a spiral shape, that is, the mixing channel 13 is a spiral channel, the sludge changes direction in real time in the spiral channel, and the movement trend is like the sludge is stirred, thereby realizing sufficient reaction with the coagulant drug.

[0063] The coagulant drug can be manually put into the drug feeding port 12, but in order to facilitate multiple drug feeding, please refer to Figure 1In some embodiments, the water treatment plate frame workshop sludge pool medicine mixer further comprises a medicine storage hopper 4 for temporarily storing coagulant medicine, the medicine storage hopper 4 is connected with the medicine feeding port 12, and the outlet of the medicine storage hopper 4 is provided with a valve, and the coagulant medicine can be automatically moved into the medicine feeding port 12 when the valve is opened, and then into the mixing bin 1.

[0064] The valve can be a mechanical valve, which can be opened manually when coagulant medicine needs to be added. In order to be more convenient and efficient, manual time is saved.

[0065] In some embodiments, the water treatment plate frame workshop sludge pool medicine mixer further comprises a controller and a timer, the valve is an electronic valve 5, and the controller is connected with the timer and the electronic valve 5. The timer is used for timing, and the controller is used for controlling the opening time and opening time of the electronic valve 5 according to the time counted by the timer, so as to realize automatic feeding of coagulant medicine in a timed and quantitative manner, which is convenient, efficient and accurate.

[0066] The selected coagulant medicine needs to be analyzed by analyzing the properties of different properties of sludge, and then several high molecular coagulants are selected for sludge conditioning test. By comparing the measured sludge specific resistance value in the test and observing the alum flower generation phenomenon in the test, as well as comparing the TP and COD concentration changes in the filtrate, the best coagulant and its dosage are determined, so that the controller can feed the coagulant medicine in the mixing bin 1 in a timed and quantitative manner, so as to improve the dewatering performance of the sludge.

[0067] In order to make the coagulant medicine more evenly fed into the mixing bin 1, in some embodiments, the medicine feeding port 12 is provided with a plurality of medicine feeding ports 12, and the plurality of medicine feeding ports 12 are arranged in sequence around the circumference of the mixing bin 1. If equal amounts of coagulant medicine are divided into each medicine feeding port 12, the coagulant medicine can be more evenly fed, and the reaction degree and reaction efficiency of the coagulant medicine and the sludge can be improved.

[0068] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they should not limit the patent protection scope of the present application. Any equivalent structure or equivalent flow replacement or modification based on the essential concept of the present application, using the content described in the specification and drawings of the present application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
