[0002] The basic detonator of industrial detonator is mainly composed of detonator shell, reinforcing cap and detonator charge. The charge is mainly divided into detonator and high explosive. Due to the advantages of DDNP (dinitrodiazophenol) such as low mechanical sensitivity, good flame sensitivity, excellent detonation performance, wide source of raw materials, low production cost and production safety, some domestic enterprises use DDNP as the detonator of industrial detonator.

[0003] The process flow of DDNP preparation is relatively complicated. The raw materials for the reaction include sodium nitrite solution, sodium picramate, pyrogallol solution, and hydrochloric acid solution. In addition, during the raw material configuration process, there are strict requirements on the concentration and quantity of each raw material. In addition, during the batching process, a filter tank needs to be added between the batching tank and the discharge tank to allow the solution to flow through the filter tank to filter out impurities in the solution.

[0004] The traditional method is to filter the solution produced after batching only through a single filtering device. If the filtering device is blocked or damaged, the entire production line needs to be suspended to clean the filtering device, resulting in a decrease in the batching efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes an automatic DDNP pharmaceutical dispensing device to solve the technical problem that in the process of filtering the prepared solution during the traditional detonator initiator preparation proposed in the above background technology, the entire preparation line needs to be shut down before the filtering equipment can be cleaned, resulting in a decrease in preparation efficiency.

[0006] To achieve the above object, the utility model provides the following technical solution: a DDNP pharmaceutical automatic batching device, comprising a batching tank and a discharge tank, wherein the batching tank and the discharge tank are connected through multiple groups of filtering units, and the filtering units include:

[0012] A first arc plate, fixedly mounted on the first mounting tube; and

[0013] The second arc plate has one end hinged to the first arc plate and the other end connected to the first arc plate through a threaded knob. The ring formed by the second arc plate and the first arc plate is arranged on the second mounting tube.

[0014] In a preferred embodiment, an annular groove is formed on the second mounting tube, and the inner side surfaces of the first arc plate and the second arc plate are both provided with arc-shaped ridges, and the arc-shaped ridges are clamped in the annular groove.

[0015] In a preferred embodiment, a first sealing ring is disposed in the annular groove, and the first sealing ring is disposed between the arc-shaped ridge and the annular groove.

[0016] In a preferred embodiment, a clamping ring is provided on the first mounting tube, a detachable second sealing ring is provided on the clamping ring, and the second sealing ring abuts against one end of the second mounting tube.

[0017] In a preferred embodiment, support rings are fixedly provided on the batching tank and the discharge tank, and two groups of the support rings are connected by a connecting frame, and a support frame is provided at the bottom of one group of the support rings.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

When the filter element 402 has been used for a long time, the corresponding set of discharge valves 102 can be closed, and the two sets of filter housings 401 can be separated after the filter unit is disassembled, so as to clean or replace the filter element 402. During the replacement process, the filtering work can be continued through other filter units without stopping the entire production line, thereby improving the work efficiency of detonator production.

[0036] like Figure 3 , 4 As shown, in this embodiment, the filter housing 401 is provided with a first mounting pipe 403 in communication therewith, the discharge valve 102 and the discharge tank 201 are both provided with a second mounting pipe 103 in communication therewith, and the second mounting pipe 103 is connected to the first mounting pipe 403 through a mounting assembly.
